Introduction
The institution of earnest money (zadatek), as codified in Article 394 of the Polish Civil Code of 23 April 1964, occupies a position of considerable practical and theoretical significance within the Polish law of obligations. It is an institution encountered with particular frequency in the context of high-value commercial and real property transactions, where contracting parties routinely stipulate earnest money clauses as a means of securing the performance of preliminary and definitive agreements alike. Despite the apparent simplicity of the statutory formula, Article 394 conceals a structural complexity that has generated sustained doctrinal controversy and produced an extensive body of judicial elaboration by the Polish Supreme Court. The correct characterisation of a sum transferred at the time of contracting as earnest money, rather than as an advance payment, a contractual penalty, or a withdrawal fee, may produce consequences of the utmost significance for the parties involved, determining not only the financial outcome of a contractual dispute but also the available remedial options and the burden of proof that each party must discharge. It is this combination of practical importance and doctrinal complexity that renders the earnest money regime a subject worthy of sustained academic analysis.
The present thesis examines the institution of earnest money as regulated under Article 394 of the Polish Civil Code of 1964, analysing its legal nature, functional scope, and doctrinal significance within the broader framework of Polish contract law. The study is organised around three complementary lines of inquiry. The first is historical and theoretical, addressing the origins of the institution, the legislative history of the current statutory provision, and the principal doctrinal classifications advanced in the Polish civil law literature. The second is normative and analytical, examining the constitutive requirements and default rules of Article 394, the scope of permissible contractual modification, and the interaction between the earnest money regime and the general rules on contractual liability. The third is jurisprudential, tracing the evolution of the Polish Supreme Court's approach to the institution and identifying the principal areas of interpretive controversy that the case law has generated. The thesis does not purport to offer a comprehensive survey of all aspects of the earnest money regime; its scope is deliberately bounded by the statutory provision of Article 394 and its judicial elaboration, leaving aside such cognate topics as the treatment of earnest money in consumer contracts, insolvency proceedings, and public procurement, which each merit separate treatment.
The thesis advances the claim that Article 394 of the Civil Code establishes a normatively coherent but structurally incomplete regime, the effective application of which is critically dependent upon judicial elaboration, particularly in respect of the concept of non-performance and the interplay between the earnest money mechanism and the general law of contractual damages. It is further argued that the Supreme Court's sustained engagement with the provision has produced a body of interpretive doctrine that offers reasonably clear guidance on the most frequently arising questions of application, but that identifiable areas of tension — most notably concerning the application of Article 394 to preliminary contracts and the question of proportionality in the adjustment of earnest money obligations — indicate that further legislative clarification or a binding resolution by an enlarged bench would materially enhance legal certainty for contracting parties. The significance of this argument extends beyond the narrow domain of earnest money law: the manner in which a deliberately incomplete statutory provision is elaborated through judicial interpretation raises questions of general importance for the theory of statutory construction and the relationship between legislation and adjudication in a codified private law system.
The academic and practical significance of the topic is reinforced by the substantial volume of litigation that earnest money clauses have generated before Polish courts, and by the degree to which the outcome of such litigation has depended upon the resolution of contested questions of legal principle rather than disputed questions of fact. The Supreme Court has addressed the earnest money provision in hundreds of decisions spanning the entire period since the entry into force of the Civil Code, and its rulings have shaped in fundamental ways the understanding of the institution available to legal practitioners, contracting parties, and doctrinal writers. An analysis of this jurisprudential body is therefore not merely an academic exercise but a necessary contribution to the practical understanding of a provision that affects a wide range of contractual relationships in Polish commercial and private life. At the same time, the doctrinal literature on Article 394 remains, in important respects, fragmented and incomplete, and the present thesis seeks to contribute to a more systematic and comprehensive understanding of the provision and its judicial application.
The structure of the thesis reflects the three lines of inquiry identified above. Chapter 1 examines the historical and theoretical foundations of the earnest money institution, beginning with the Roman law of arra and tracing the development of the concept through its reception into continental legal systems and its pre-codification treatment in Polish legal doctrine. Particular attention is devoted to the legislative history of Article 394, including the influences of the pre-war Polish Code of Obligations of 1933 and of Soviet civil law doctrine upon the final statutory formulation. The chapter proceeds to analyse the principal doctrinal classifications of earnest money advanced in the Polish civil law literature, examining the competing characterisations of the institution as a security device, a contractual penalty, and a sui generis mechanism with distinctive proprietary and obligatory dimensions. It concludes with a systematic comparison of earnest money and the functionally proximate institutions of the contractual penalty (kara umowna), the advance payment (zaliczka), and the right of withdrawal (odstępne), clarifying the criteria employed by doctrine and case law to differentiate their respective legal regimes. This comparative analysis provides the conceptual foundation for the normative inquiry undertaken in the succeeding chapter.
Chapter 2 undertakes a systematic doctrinal analysis of the normative content of Article 394, proceeding through the five principal dimensions of the provision's application. The chapter begins with an analysis of the structural elements and formal requirements of a valid earnest money arrangement, addressing the prerequisites of agreement, delivery, and the relationship between the earnest money clause and the underlying contract. It then examines the default rules established by Article 394 §1, governing the fate of earnest money upon non-performance, including the conditions under which the recipient may retain the sum and the transferor may demand its double return, and the doctrinal controversies surrounding the concept of non-performance as a trigger for the statutory mechanism. Attention is subsequently directed to the question of contractual modification under Article 394 §3, investigating the extent to which the parties may, by agreement, modify or exclude the default regime and the limits imposed by mandatory provisions and general principles of contract law. The chapter also analyses the legal consequences prescribed by Article 394 §2 and §3 for scenarios other than unilateral non-performance, including proper performance, consensual termination, and supervening impossibility, before concluding with an examination of the interaction between the earnest money regime and the general rules on compensation for non-performance under Articles 471 to 486 of the Civil Code. The question of whether the injured party may simultaneously pursue both the earnest money remedy and a claim for damages is among the most contested aspects of the provision's normative content, and it is addressed in detail.
Chapter 3 turns to the jurisprudential dimension of the inquiry, tracing the evolution of the Polish Supreme Court's approach to earnest money over more than six decades of judicial engagement with the institution. The chapter begins by charting the development of the Court's position on the legal nature and fundamental characteristics of zadatek, identifying the principal lines of reasoning adopted by successive benches and the degree of continuity or departure in judicial doctrine. It proceeds to analyse the Supreme Court's interpretation of the non-performance requirement, examining the contested questions of fault, partial performance, and the treatment of anticipatory breach in the relevant case law. A dedicated subchapter addresses the extensive body of Supreme Court jurisprudence concerning earnest money stipulated in preliminary contracts (umowy przedwstępne), with particular attention to disputes arising from real property transactions and the conditions under which the earnest money remedy is available when a definitive contract is not concluded — an area that has produced some of the most complex and practically significant rulings in the Court's treatment of the institution. The chapter concludes by examining three specific doctrinal controversies arising from Supreme Court decisions: the applicability of the mitigation principle, the admissibility of judicial reduction of earnest money obligations by analogy to the provisions governing contractual penalties, and the limits of party autonomy in configuring the earnest money regime. These controversies are treated not merely as isolated questions of case law but as illustrations of the broader tensions within the statutory regime that the Court has been called upon to resolve through interpretive means.
The methodological approach adopted throughout the thesis is that of doctrinal legal analysis, combining close textual interpretation of the statutory provision with systematic examination of the academic literature and critical analysis of judicial decisions. Primary sources, comprising the statutory text of the Civil Code, the decisions of the Polish Supreme Court, and the preparatory materials relevant to the legislative history of Article 394, are supplemented by the dominant positions in Polish civil law doctrine. Where appropriate, comparative reference is made to cognate institutions in other legal systems, including the Roman law sources from which the Polish institution in part derives, though the thesis does not purport to undertake a comprehensive comparative analysis. The analysis of Supreme Court decisions is not intended as an exhaustive catalogue of the relevant case law but as a selective and critical examination of the rulings most significant for the doctrinal questions addressed in each subchapter.
It may finally be observed that the choice of earnest money as the subject of a thesis in Polish civil law requires no elaborate justification. The institution stands at the intersection of several of the most fundamental problems in the law of obligations — the nature of contractual security, the relationship between agreed and judicially assessed remedies, the scope of party autonomy, and the limits of statutory incompleteness — and its analysis therefore affords an opportunity to engage with questions of general significance for the understanding of Polish private law. The earnest money regime is, moreover, an institution whose practical importance is not in decline: the volume of earnest money litigation before Polish courts has, if anything, increased in the decades since the enactment of the Civil Code, reflecting the enduring role of the institution in the structuring of high-value contractual relationships. The need for clear, systematic, and critically informed analysis of Article 394 and its judicial elaboration is therefore as pressing as it has ever been, and it is to that need that the present thesis seeks, within the limits of its defined scope, to respond.
Chapter 1: The Historical and Theoretical Foundations of Earnest Money in Polish Civil Law
1.1. The Roman-Law Origins and the Pre-Codification Tradition
The institution of earnest money as codified in Article 394 of the Polish Civil Code of 1964 cannot be adequately understood in isolation from the extended historical tradition from which it emerged. Its intellectual genealogy reaches to Roman antiquity, where the device of the arra (alternatively rendered arrha) occupied a recognised, if doctrinally contested, position within the law of contracts. A historically informed analysis of the institution is not merely an exercise in scholarly antiquarianism: the reception of Roman legal concepts into the Continental tradition of private law shaped, in fundamental ways, the structural choices made by modern legislators and the interpretive frameworks available to courts and doctrinal writers. As Philip Thomas has observed in his study of good faith in the Roman law of contracts, any reading of Roman legal institutions through a modern lens risks imposing contemporary frameworks upon material that responded to very different social and economic conditions — a methodological caveat that applies with particular force to the comparative analysis of the arra.[1, p. 20] This caveat does not, however, counsel against historical analysis; it counsels in favour of methodological rigour.
The Roman arra is attested in classical juristic sources as a device closely associated with the contract of sale (emptio venditio), though its application was not confined to that nominate contract. In its earliest and most basic form, the arra functioned as a token of confirmation: a sum of money or an object of value delivered by one contracting party to the other as tangible evidence that an agreement had been concluded and that the parties entertained genuine contractual intent. In this confirmatory capacity — designated by later doctrine as arra confirmatoria — the delivered object served primarily an evidential and symbolic purpose, marking the solemnity of the transaction and providing a form of assurance against subsequent denial of the agreement's existence. The delivery of the arra was not, under classical Roman law, a constitutive element of the sale: as Ulpian's formulation recorded in the Digest stated, the sales contract was perfected by consent alone, not by the discounting of the price or by any real delivery — non enim numeratio pretii, sed conventio perficit sine scriptis habitam emptionem.[6] The consensual character of the emptio venditio thereby relegated the arra to a confirmatory rather than a constitutive function in classical law.
The transformation of the arra from a purely confirmatory token into a mechanism conferring withdrawal rights — the arra poenitentialis — is associated primarily with the Justinianic legislation of the sixth century AD. In a constitution incorporated into the Codex, Justinian provided that where an arra had been given in connection with a contract not yet reduced to writing, the purchaser who withdrew would forfeit the arra, while the vendor who withdrew would be obliged to return it in double. This provision introduced a structural duality that would prove extraordinarily durable in the subsequent history of the institution: the arra as confirmation on the one hand, and the arra as a bilateral withdrawal penalty on the other. The fundamental tension resided in the question of whether parties, upon delivering an arra, thereby implicitly conferred upon themselves a right to withdraw — a reading that would transform every earnest money clause into a potential obstacle to specific performance — or whether the confirmatory function remained primary and the withdrawal right arose only upon express stipulation. This tension would persist across centuries of scholarly commentary and would ultimately find a legislative resolution, though not a universally accepted one, in the text of modern codifications.
The transmission of the Roman arra into the Continental legal tradition was mediated chiefly by the Corpus Juris Civilis of Justinian and by the work of the glossators and commentators who elaborated upon it from the eleventh century onwards. As demonstrated in the study of the mandatum in the thought of the glossators and commentators, the revival of Roman legal studies at Bologna under Irnerius in the late eleventh century provided the institutional and intellectual foundation for a systematic engagement with the Justinianic sources across the full range of contractual institutions — including devices of confirmation, security, and penalty closely analogous to the arra.[9, p. 12] The principle of pacta sunt servanda, cited regularly in the deliberations of early modern courts as a foundational maxim derived from the Corpus Juris Civilis, formed the backdrop against which the earnest money mechanism operated: if contracts were inexorably binding, the earnest money served as both the expression and the consequence of that binding force, deterring parties from treating their obligations as optional.[2, p. 179] The comparative study of ancient and medieval contractual practice further illuminates the social functions of the arra: in East Central Europe, the millenary presence of contractual instruments is attested by the wax tablets recovered from the ancient mineshaft at Alburnus Maior in Roman Dacia, documenting loan transactions of the second century AD that contained express provisions for interest and repayment, demonstrating that Roman contractual discipline operated in practice, not merely in juristic theory.[7, p. 13]
The pre-codification tradition in Polish territories must be understood against the background of the partition era, during which three distinct legal systems operated concurrently across the lands that would constitute the restored Polish state after 1918. In the Kingdom of Poland (the Congress Kingdom), the Napoleonic Code of 1804 applied, containing in Articles 1590 and 1659–1673 provisions on earnest money (arrhes) in the context of sale contracts and contractual options, reflecting a synthesis of Roman and customary French law. In the territories subject to German rule, the Bürgerliches Gesetzbuch (BGB) of 1900 governed civil matters, regulating the Draufgabe (earnest money) in §§ 336–338 and treating it presumptively as a confirmatory token whose forfeiture was excluded absent express agreement. In Galicia, the Austrian Allgemeines Bürgerliches Gesetzbuch (ABGB) applied, with its own distinct treatment retaining closer affinities to the Roman confirmatory model. Despite terminological and functional divergences across these three systems, all shared a common Roman-law heritage and a structural duality between earnest money as confirmation and earnest money as a withdrawal device.
- Roman arra confirmatoria: token delivered as evidence of contractual seriousness, without penal consequences upon non-performance; associated with classical Roman law and the consensual character of emptio venditio.
- Roman arra poenitentialis: bilateral withdrawal device whereby the defaulting purchaser forfeits the arra and the defaulting vendor returns it in double; introduced by Justinianic legislation in the sixth century AD.
- Napoleonic Code (arrhes): Articles 1590 and 1659–1673; treated earnest money as conferring a unilateral right of withdrawal in the context of sale contracts.
- German BGB (§§ 336–338, Draufgabe): presumptively confirmatory, with forfeiture excluded unless expressly stipulated by the parties.
- Austrian ABGB: distinct provisions applicable in Galicia, retaining closer affinities to the Roman confirmatory model without strong penal presumptions.
The doctrinal controversy generated by the Roman heritage — most acutely, the question of whether the arra was primarily a confirmation or a withdrawal device — was thus bequeathed entire to the codification debates of the twentieth century, where it found its contemporary resolution, though not without continued controversy, in the text of Article 394 of the 1964 Civil Code.
1.2. The Legislative History of Article 394 of the Civil Code of 1964
The legislative history of Article 394 of the Polish Civil Code of 1964 is inseparable from the broader history of private law codification in Poland during the twentieth century — a history marked by the successive challenges of national unification, social transformation, and ideological constraint. The starting point of that history is the work of the Codification Commission of the Second Polish Republic (Komisja Kodyfikacyjna II RP), established by statute in 1919 with the mandate to produce a unified system of private law for the restored Polish state. The Commission operated in a context of considerable legal pluralism: the three partitioned zones had been governed for more than a century by distinct legal orders, and commercial and civil transactions in each zone had been conducted under assumptions about the legal effects of earnest money that differed in significant respects. The Codification Commission's achievement in the field of contract law was the Law on Obligations of 1933 (Prawo zobowiązań), enacted as a Presidential Regulation of 27 October 1933 and entering into force on 1 July 1934.[38]
Article 79 of the 1933 Law on Obligations introduced the first unified Polish regulation of earnest money (zadatek), superseding the divergent rules of the Napoleonic Code, the BGB, and the ABGB and establishing a single national regime. The debates within the Codification Commission on the proper treatment of earnest money engaged leading private law scholars of interwar Poland. The fundamental question was whether the default rule should treat the earnest money primarily as a confirmation — returnable upon non-performance — or as a liquidated sanction, with the party in default forfeiting or being required to return double. The Commission ultimately opted for the penal default model, thereby aligning the Polish solution more closely with the Napoleonic tradition than with the German BGB's presumption against forfeiture. Article 79 of the 1933 Law on Obligations established that, absent a contrary agreement, the party who gave earnest money and then failed to perform should lose it, while the party who received earnest money and then failed to perform should return it in double. This formulation preserved the Roman dual structure — confirmatory function plus penal consequence — while resolving in favour of automaticity: no judicial intervention was required to trigger the forfeiture or doubling, and the proof of actual loss by the aggrieved party was not a condition for the operation of the mechanism.
The promulgation of the Polish Civil Code of 1964, which entered into force on 1 January 1965, transplanted the essential architecture of Article 79 of the 1933 Law on Obligations into the socialist codification. Article 394 of the 1964 Code established, in paragraph 1, the default confirmatory-penal regime: absent a contrary contractual provision or established usage, earnest money delivered at the time of contracting carried the following significance — in the event of non-performance by the party who gave the earnest money, the other party could withdraw from the contract and retain the sum; in the event of non-performance by the party who received it, the other party could withdraw and demand its double return. Paragraph 2 provided that in the event of the contract's performance, the earnest money was to be credited against the transferor's obligations or, if credit was not feasible, returned. Paragraph 3 addressed dissolution by mutual consent and supervening impossibility, prescribing the return of the earnest money without doubling in those circumstances. The structure of Article 394 thus preserved and refined the interwar regulatory model while situating it within the systematic framework of the new codification, which aimed at comprehensiveness and conceptual rigour in the organisation of the law of obligations.[39]
The ideological context of the 1964 codification is relevant to an understanding of how Article 394 was interpreted in the first decades after its entry into force. The civil law of the Polish People's Republic operated under the dominant principle of contractual discipline and plan-fulfilment: parties were expected to perform their contractual obligations in accordance with the socialist economic plan, and instruments that legitimised unilateral withdrawal — such as the earnest money mechanism — were viewed with a degree of institutional suspicion. This orientation did not lead to the formal exclusion of the earnest money institution, which retained significant practical importance in transactions between private individuals not subject to the planning regime, but it did shape both the restrictive interpretation of Article 394 in certain doctrinal contexts and the limited attention devoted to its relationship with the general rules on civil liability for non-performance under Articles 471–486. The political and economic transformation of 1989 and the transition to a market economy produced a dramatic expansion in the practical importance of Article 394: the liberalisation of real property markets generated an enormous volume of preliminary contracts (umowy przedwstępne) in which earnest money clauses became standard contractual devices, and the resulting intensification of judicial scrutiny by the Supreme Court of Poland (Sąd Najwyższy) fundamentally shaped the modern doctrinal understanding of the institution.[7, p. 13]
| Instrument | Year of Entry into Force | Relevant Provision | Default Rule upon Non-Performance |
|---|---|---|---|
| Napoleonic Code (Congress Kingdom) | 1808 | Arts. 1590, 1659–1673 | Withdrawal right presumed; arrhes forfeited or doubled |
| German BGB (Western territories) | 1900 | §§ 336–338 (Draufgabe) | Confirmatory presumption; forfeiture requires express agreement |
| Austrian ABGB (Galicia) | 1811 | §§ 908–911 | Confirmatory function; penal consequences by agreement only |
| Law on Obligations of 1933 | 1934 | Art. 79 | Penal default: forfeiture or doubling without proof of loss |
| Civil Code of 1964 | 1965 | Art. 394 §§ 1–3 | Penal default; interaction with damages; party autonomy preserved |
It should be noted that the amendments and interpretive shifts occasioned by the post-1989 transformation did not produce any formal legislative revision of Article 394 itself: the text of the provision has remained substantially unchanged since 1964, and the evolution of its application has been effected primarily through judicial elaboration by the Supreme Court rather than through legislative action. This characteristic — the normative stability of the statutory text combined with its continuous doctrinal and judicial development — lends particular importance to an analysis of the case law, which is undertaken in Chapter 3 of this thesis. For present purposes, it suffices to observe that the legislative history of Article 394 reveals a clear line of continuity from the Roman arra through the interwar codification of 1933 to the contemporary provision, a continuity that is the product of deliberate choice rather than unreflective inheritance.
1.3. The Legal Nature of Earnest Money: Between Security, Penalty, and Consideration
The question of the legal nature of earnest money (zadatek) has occupied a central position in Polish civil law doctrine since the promulgation of Article 394 of the Civil Code. It is a question of genuine systematic importance: the characterisation of the institution determines its place within the taxonomy of civil obligations, the conditions for the validity of earnest money clauses in various contractual contexts, and the interaction of the earnest money mechanism with the general regime of civil liability for non-performance under Articles 471–486 of the Civil Code. Three principal characterisations have been advanced in the Polish legal literature, each capturing a genuine dimension of the institution while failing, in isolation, to account for its full normative complexity.[40]
The first and historically dominant characterisation treats earnest money as a form of contractual security (zabezpieczenie kontraktowe). Under this view, the earnest money clause functions as an accessory obligation whose economic purpose is to incentivise performance by imposing a pre-agreed, asymmetrical economic loss upon the non-performing party. The delivered sum functions as a form of real security: like a pledge or a guarantee, the earnest money involves an actual transfer of value at the time of contracting, creating an economic interest in the retained sum that differentiates it from the purely obligatory character of the contractual penalty (kara umowna). The in terrorem effect of the earnest money — the prospect of immediate, non-judicial forfeiture or doubling upon non-performance — reinforces the analogy to security instruments whose function is to strengthen the protected party's position in anticipation of potential default. The emphasis in Roman legal doctrine on the role of bona fides as an objective standard imposing ethical constraints upon contracting parties adds a further dimension to this analysis: in the Roman consensual contracts, including the emptio venditio, the clause quidquid dare facere oportet ex fide bona allowed courts to enforce obligations grounded in good faith and trust, and the arra functioned in part as a tangible expression of that commitment.[6] The parallel between Roman fides and the function of earnest money as a pledge of contractual seriousness is thus not merely metaphorical but reflects genuine structural affinities between the two institutions.
The security characterisation, however, is subject to a significant objection: it assimilates earnest money to a category that encompasses instruments of fundamentally different structures. Unlike a pledge or a guarantee, earnest money does not merely protect the aggrieved party against default by the counterparty: it also creates in the party who gave the earnest money the right to withdraw from the contract upon forfeiture of the paid sum, thereby generating a bilateral instrument of contract exit rather than a unilateral security device. Furthermore, the security characterisation does not adequately explain why the earnest money mechanism operates independently of proof of actual loss — a feature that distinguishes it from ordinary compensatory security — or why it confers a right of withdrawal rather than merely a right to compensation. The analogy to security law therefore illuminates one dimension of the institution while obscuring the others.
The second characterisation, influential in German-language scholarship and partially reflected in the Polish literature prior to the 1933 unification, treats earnest money as a form of advance payment on account of the contract price, whose primary significance lies in its evidential and confirmatory function. This view finds textual support in Article 394 § 1, which expressly characterises the earnest money as "confirmation of the conclusion of the contract" (potwierdzenie zawarcia umowy) before specifying its consequences upon non-performance. However, as the Roman legal history demonstrates, the confirmatory characterisation alone cannot account for the normative development of the institution: the transformation of the arra from a purely confirmatory token into a bilateral withdrawal device under Justinianic law reflected a deliberate legislative choice to assign the institution a penal function that was not derivable from its confirmatory dimension alone. Moreover, the confirmatory characterisation would assimilate earnest money to the advance payment (zaliczka), a related but distinct institution that is discussed in the following subchapter, thereby erasing a distinction that Article 394 implicitly presupposes.[1, p. 21]
The third and analytically most adequate characterisation treats earnest money as a sui generis institution that combines elements of a penal clause, a real security device, and a confirmation of contractual intent, without being reducible to any single pre-existing category within the law of obligations or property. This characterisation acknowledges the multi-functional character of the institution: it is simultaneously confirmatory (providing evidence of the parties' serious intent at the time of contracting), real (requiring an actual transfer of value rather than a mere obligatory stipulation), accessory (dependent upon the validity and continued existence of the principal contract), penal (imposing a pre-agreed economic sanction upon the non-performing party without the need for proof of loss), and withdrawal-enabling (creating in each party the right to exit the contract upon suffering the economic consequences of the earnest money rule). The sui generis character of the institution is perhaps most clearly demonstrated by the fact that the earnest money right — the right to retain or demand double the sum — is not triggered by a breach in the ordinary sense of Article 471 but arises automatically from the fact of non-performance, independently of fault in all cases where the regime of Article 394 § 1 applies.[17]
- Security characterisation: emphasises the in terrorem deterrent function and the real (property-like) character of the earnest money transfer; underpins the analogy to pledge and guarantee but fails to account for the bilateral withdrawal dimension and the independence of the mechanism from proof of actual loss.
- Confirmation/advance characterisation: emphasises the evidential function and the partial credit against the contract price; supported by the text of Article 394 § 1 but insufficient to explain the automatic penal consequences and risks assimilation to the legally distinct zaliczka.
- Sui generis characterisation: acknowledges the multi-functional character of the institution, treating it as a complex legal device combining real, accessory, penal, and withdrawal-enabling elements; analytically most adequate but requires careful delineation of its interaction with adjacent legal categories, particularly the contractual penalty and the right of withdrawal under Article 396.
A further dimension of the legal nature question concerns the proprietary or obligatory character of the right to retain or demand double the earnest money. This classification carries practical consequences in insolvency contexts and in situations where the received earnest money sum has been dissipated or transferred: if the right of the transferor to demand double return is merely obligatory, it ranks as an unsecured claim against the estate of an insolvent recipient; if it partakes of a proprietary character, it may be asserted against third parties and secured creditors. Polish doctrine has generally treated the earnest money right as obligatory in character, arising from the contractual relationship between the parties rather than creating a right in rem over the delivered sum, and this position reflects the consensual foundations of Polish contract law as informed by the Roman tradition. The coherence of this position is confirmed by the fact that the earnest money mechanism, like the actiones bonae fidei of Roman law, operates within a framework that prioritises the protection of reasonable expectations and the deterrence of opportunistic non-performance over the creation of real security interests.[6]
1.4. The Distinction Between Earnest Money and Functionally Proximate Institutions
The analytical precision required by Article 394 of the Civil Code demands a systematic differentiation of earnest money from the institutions with which it shares functional characteristics while differing in legal structure, conditions of validity, and legal consequences. In the comparative legal framework established by the ius commune and elaborated by the European codifications of the eighteenth and nineteenth centuries, the boundary between earnest money, the contractual penalty, the advance payment, and the right of withdrawal was a matter of doctrinal contest rather than self-evident categorisation. As Gábor Hamza has observed in his comparative study of ancient and modern laws, the use of a common terminology across different legal systems can mask substantial differences in the content and function of formally similar institutions — a risk that is particularly acute in the case of earnest money, which has accumulated different meanings across different legal traditions.[4] The purpose of the present subchapter is to identify the criteria that distinguish earnest money from each of the proximate institutions, thereby delimiting precisely the normative domain of Article 394.
The most important and most frequently litigated distinction in Polish civil law is that between earnest money (zadatek) and the contractual penalty (kara umowna), regulated in Articles 483–485 of the Civil Code. Both institutions serve a liquidated-damages function insofar as they establish in advance the economic consequences of non-performance without requiring proof of actual loss sustained by the aggrieved party. Both operate as deterrents against default, and both permit the aggrieved party to claim a fixed sum upon the counterparty's failure to perform. Despite these functional parallels, the two instruments differ in several respects of both analytical and practical significance. The contractual penalty is a purely obligatory device: it is created by a written clause specifying the sum or percentage to be paid upon a defined event of non-performance, and it does not involve any transfer of value at the time of contracting. Earnest money, by contrast, is a real institution in the technical sense: its constitutive element is the actual delivery of a sum of money or other movable object at the time of contracting, and the forfeiture or doubling mechanism operates upon the value thus transferred. Furthermore, the contractual penalty is unidirectional — it imposes an obligation on the breaching party to pay the stipulated sum to the aggrieved party — while the earnest money rule is bilateral, entitling either party to invoke the mechanism depending upon which of them has failed to perform. The question of whether a contractual penalty and an earnest money clause may validly coexist in the same contract — and whether the exercise of one remedy precludes resort to the other — has generated significant Supreme Court jurisprudence, the analysis of which is deferred to Chapter 3 of this thesis.
The second comparison of practical importance is between earnest money and the advance payment (zaliczka). Unlike earnest money, the advance payment has no independent statutory definition in Polish civil law: it is a creature of contractual practice and doctrinal elaboration, understood as a partial payment on account of the contract price made in advance of full performance. The legal consequences of a zaliczka upon non-performance differ fundamentally from those of a zadatek: the advance payment must be returned in full to the party who made it in the event of non-performance, regardless of which party bears responsibility for the failure to perform, and no forfeiture or doubling occurs. The advance payment thus imposes no penal consequence upon the defaulting party and creates no bilateral withdrawal right. The practical significance of the distinction between zadatek and zaliczka arises most acutely in cases where the parties have not clearly specified the character of a transferred sum: in such cases, Article 394 § 1 provides a statutory presumption establishing that "in case of doubt" earnest money is deemed to have been given. The operation of this presumption has been a significant source of litigation, particularly in the context of preliminary contracts for the sale of immovable property, where the characterisation of the transferred sum may determine whether a defaulting vendor must return the sum doubled or merely restore the original amount paid.[2, p. 179]
The third comparison concerns the distinction between earnest money and the withdrawal fee (odstępne), regulated under Article 396 of the Civil Code. The withdrawal fee is a contractually stipulated sum whose payment confers upon the paying party the right to withdraw from the contract — that is, to treat the contractual relationship as dissolved by a unilateral declaration of will. Unlike the earnest money mechanism, which operates as a consequence of non-performance, the withdrawal fee operates as the consideration for the deliberate exercise of a contractual exit right: the party who invokes it does so by choice, not in response to a breach by the counterparty. The comparison between zadatek and odstępne is significant because Article 394 § 1 itself embeds a form of withdrawal right in the earnest money mechanism — the right to "withdraw from the contract" in the event of the counterparty's non-performance — but the conditions for the exercise of that right and its legal effects differ from those prescribed by Article 396. The Justinianic arra poenitentialis may be identified as the historical ancestor of both institutions, insofar as it introduced into Roman law the idea that the delivery of a sum of money could serve as the consideration for a right to exit a concluded agreement; the subsequent doctrinal differentiation of the two instruments reflects the elaboration of Roman sources within the ius commune tradition and the differentiated legislative choices of the modern codifications.

| Bilateral or unilateral | Bilateral | Per clause (typically unilateral) | Not applicable | Bilateral (either party may exercise) |
| Proof of actual loss required | No | No (Art. 484 § 1) | Not applicable | No |
| Judicial reduction available | Disputed (Art. 484 § 2 by analogy) | Yes (Art. 484 § 2) | Not applicable | Not provided |
| Statutory presumption of applicability | Yes (Art. 394 § 1 in fine) | No | No | No |
The fourth comparison addresses the relationship between earnest money and the guarantee (poręczenie) as well as the deposit (depozyt) — institutions that share with earnest money the characteristic of involving an actual transfer or commitment of value in connection with a contractual relationship but differ fundamentally in their normative character. The guarantee is a personal security obligation assumed by a third party in respect of another's debt, while the deposit involves the delivery of a thing for safekeeping without the penal consequences of earnest money. Neither instrument embeds the bilateral withdrawal-penalty mechanism central to the legal nature of zadatek, and neither is governed by Article 394. The analytical utility of comparing earnest money with these more remotely related institutions lies primarily in the negative delimitation of the concept: by establishing what earnest money is not, the comparison clarifies the conditions under which Article 394 is applicable and assists in the interpretation of contractual provisions whose characterisation might otherwise remain uncertain.[7, p. 14]
The interpretive principle applicable across all four comparisons is that the characterisation of a transferred sum as earnest money is a matter of the parties' contractual intent as reconstructed in accordance with Articles 65 and 394 of the Civil Code, and that the legal consequences of that characterisation are far-reaching and non-trivial. The determination of whether a sum transferred at the time of contracting constitutes earnest money, an advance payment, or a withdrawal fee may produce radically different legal outcomes for the parties, particularly in the high-value real property transactions that dominate the contemporary jurisprudence of the Supreme Court on Article 394. Doctrinal precision in this area is therefore not merely an academic aspiration but a condition of legal certainty for contracting parties whose rights may depend upon the correct classification of the sums they have exchanged.
Chapter 2: The Normative Content of Article 394 of the Civil Code — A Doctrinal Analysis
The institution of earnest money as presently regulated in Polish civil law derives its normative content primarily from Article 394 of the Civil Code of 23 April 1964, a provision of considerable structural complexity whose three paragraphs establish both the constitutive requirements of a valid earnest money arrangement and the legal consequences that follow from performance, non-performance, and the several intermediate situations recognised by the legislature. The present chapter undertakes a systematic doctrinal analysis of that provision, proceeding from the formal prerequisites of a valid earnest money clause through the default regime governing non-performance to the contractually modifiable aspects of the statutory scheme and, finally, to the question of how earnest money interacts with the general system of contractual remedies under the Civil Code. The analysis draws upon the dominant positions in Polish civil law doctrine, with reference where appropriate to comparative solutions that illuminate the choices made by the Polish legislature and the interpretive difficulties that those choices have generated.
2.1. The Structural Elements and Formal Requirements of a Valid Earnest Money Clause
The threshold question that must be addressed before the legal consequences of earnest money may be considered is that of the conditions under which a valid earnest money arrangement arises in the first place. Article 394 of the Civil Code does not itself provide an explicit definition of earnest money, but from the structure and content of the provision it is possible to reconstruct the constitutive requirements that must be satisfied for the institution to arise in any particular contractual relationship. Three elements are identified in Polish doctrine as necessary and jointly sufficient for the constitution of a valid zadatek: an agreement of the parties designating a specific sum of money or other movable thing as earnest money; the actual delivery of that sum or thing at the time of contracting; and the presence of a valid underlying contract to which the earnest money clause attaches.[18] Each of these elements raises distinct interpretive questions that have been the subject of sustained doctrinal attention.
The requirement of actual delivery — expressed in doctrinal terms as the realny charakter zadatku, meaning the real character of the earnest money stipulation — is the most consequential formal requirement and the one that most sharply distinguishes earnest money from the contractual penalty. The dominant view in Polish civil law holds that zadatek belongs to the category of real stipulations (czynności realne): that is, the clause does not produce legal effect by agreement alone but only upon the physical transfer of the agreed sum or object. A contractual provision stating that "the buyer gives earnest money of X zloty" without any corresponding transfer of funds does not, in this view, give rise to a valid earnest money arrangement; the clause remains a mere declaration of intent until actual delivery occurs.[41] This approach has significant practical implications, particularly in cases where the parties have executed a written contract including an earnest money clause but where the designated sum has not yet been transferred at the time of signing. In such cases, the majority position in doctrine and case law holds that the earnest money relationship arises only at the moment of actual delivery, and that until that moment the provisions of Article 394 do not apply to the contractual relationship.
The subject matter of earnest money under Polish law is governed by the language of Article 394 itself, which refers to "money or a movable thing" (pieniądze albo rzecz ruchoma). This formulation gives rise to the question of whether any movable thing of determinable value may serve as earnest money, or whether the provision should be read restrictively to encompass only money and things of money-like character. The prevailing doctrinal view accepts the broader reading: any movable thing capable of being valued in money terms may constitute earnest money, provided that the parties have expressly or implicitly designated it as such. The practical significance of this position is limited, since the overwhelming majority of earnest money arrangements in contemporary Polish commercial practice involve transfers of sums of money rather than physical objects; nonetheless, the theoretical openness of the provision to non-monetary earnest money has doctrinal consequences for the rules governing return of earnest money in specie where the thing handed over is no longer available.[19]
The question of formal requirements for the earnest money clause presents a relatively clear answer in Polish law: no special form is required for the clause beyond the form applicable to the underlying contract. Where the main contract is subject to a mandatory written form — as is the case, notably, for preliminary contracts concerning real property when the parties wish to preserve the right to seek specific performance — the earnest money clause must be embodied in a document satisfying that form. Where, however, the underlying contract is subject to no mandatory form requirement, the earnest money clause may in principle be agreed orally, though evidential difficulties will arise in practice. The timing of delivery is equally important: while Article 394 refers to earnest money given "at the conclusion of the contract" (przy zawarciu umowy), Polish doctrine does not require contemporaneous delivery in the strict sense; a delivery effected shortly after the conclusion of the contract may be treated as satisfying the timing requirement if the circumstances indicate that it was contemplated as part of the contractual arrangement.[20]
The practical distinction between earnest money and the advance payment (zaliczka) is of fundamental importance and is addressed by the statutory presumption contained in the final sentence of Article 394 §1: "in case of doubt" (w razie wątpliwości), a sum given at the conclusion of a contract is presumed to constitute earnest money. This presumption operates as a default rule and may be displaced by evidence of the parties' contrary intent. The following list identifies the principal criteria employed by doctrine and case law to distinguish earnest money from the advance payment in cases of ambiguity:
- The designation employed by the parties in the contract: use of the term zadatek creates a strong presumption in favour of earnest money, while use of zaliczka or equivalent language creates a corresponding presumption against it, though the legal nature of the arrangement is ultimately determined by its substantive content rather than its label;
- The presence or absence of explicit forfeiture/doubling language: a clause providing expressly that the transferred sum may be retained or demanded in double in the event of non-performance is indicative of an earnest money arrangement;
- The proportion of the transferred sum to the total contract price: a very small payment on account (rata) is more naturally characterised as an advance payment, while a substantial deposit — particularly one amounting to ten percent or more of the agreed price — is more consistent with the earnest money function;
- The context and purpose of the payment: where the transferred sum is characterised as a guarantee of performance or a deterrent against default, the earnest money classification is supported; where it is expressly described as a partial advance against the purchase price without any penal function, the advance payment classification prevails;
- The parties' commercial sophistication and the assistance of legal counsel in drafting: the statutory presumption in favour of earnest money may be given less weight where unsophisticated parties have used the term zaliczka without appreciating the legal distinction between the two institutions.
The foregoing analysis demonstrates that the constitution of a valid earnest money arrangement requires the satisfaction of substantive conditions whose fulfilment may not always be evident from the text of the contract alone. The interpretive challenges posed by ambiguous contractual provisions in this area are among the most persistent sources of litigation in Polish civil law, particularly in the context of real property transactions.
2.2. The Default Rules of Article 394 §1 and Their Scope of Application
Article 394 §1 of the Civil Code establishes the default regime applicable to earnest money in the event of non-performance, providing that in the absence of a contrary contractual stipulation, the party who gave the earnest money and subsequently fails to perform may withdraw from the contract and thereby forfeit the sum given, while the party who received the earnest money and subsequently fails to perform may be required by the other party to return double the amount received. This bilateral mechanism — known in doctrine as the przepadek zadatku (forfeiture of earnest money) and zwrot podwójnego zadatku (return of double earnest money) respectively — constitutes the normative core of the Article 394 regime and the primary point of reference for the extensive body of Supreme Court jurisprudence considered in Chapter 3 of this thesis.[21]
The legal nature of the forfeiture and doubling mechanism has been a subject of sustained controversy in Polish civil law doctrine. The dominant position characterises the earnest money remedy as a form of liquidated damages (zryczałtowane odszkodowanie): the parties have agreed in advance, by incorporating an earnest money clause into their contract, upon the economic consequence of non-performance without the need for the aggrieved party to establish actual loss. On this view, the earnest money mechanism is structurally analogous to the contractual penalty under Articles 483–484, the key difference being that earnest money involves an actual transfer of value at the time of contracting rather than a promise to pay upon breach. The minority position, advanced by a number of commentators, treats the earnest money mechanism as a sui generis institution with a predominantly penal rather than compensatory character, noting that the bilateral structure of the remedy — which imposes different consequences depending upon which party is in breach — is without parallel in the general law of damages and reflects a concern with deterrence and symmetry that is characteristic of punitive rather than compensatory sanctions.[42]
The conditions that must be satisfied for the default rules of Article 394 §1 to apply are identified in doctrine as follows. First, there must be non-performance of the contract in the sense of a total failure to perform the contractual obligation, as opposed to defective or partial performance. The significance of this condition is considerable: Polish doctrine and case law distinguish between non-performance and improper performance, treating only the former as capable of triggering the Article 394 §1 mechanism in the absence of a contrary contractual agreement. Second, the non-performance must be attributable to the failing party in the sense of being caused by circumstances within that party's sphere of risk; the element of wina (fault) in the broad civil-law sense is required, encompassing both intentional non-performance and negligent failure to perform. Third, the party entitled to invoke the earnest money mechanism must exercise the right to withdraw from the contract by means of an active declaration of will (oświadczenie o odstąpieniu od umowy); the financial consequences of Article 394 §1 are, on the dominant doctrinal view, conditional upon the prior exercise of this withdrawal right and do not arise automatically from the fact of non-performance alone.
The following table summarises the operation of the default regime under Article 394 §1 depending upon the identity of the party in breach:
| Party in Breach | Right of Aggrieved Party | Financial Consequence | Proof of Loss Required |
|---|---|---|---|
| Party who gave the earnest money | Withdraw from the contract and retain the earnest money received | Forfeiture of the sum given (przepadek zadatku) | No |
| Party who received the earnest money | Withdraw from the contract and demand double the sum given | Return of double the earnest money (zwrot podwójnego zadatku) | No |
| Neither party (mutual agreement or impossibility) | No withdrawal under Art. 394 §1; see Art. 394 §2 | Return of sum as given (no penalty) | Not applicable |
The scope of application of the default rules under Article 394 §1 extends in principle to all bilateral contracts, though specific statutory regimes may exclude or modify the earnest money mechanism in respect of particular contract types. The interaction between Article 394 §1 and the general rules on the effects of withdrawal from a contract under Articles 395 and 491 of the Civil Code requires particular attention: while withdrawal under Article 395 operates prospectively to dissolve the contractual relationship, the withdrawal embedded in the Article 394 §1 mechanism is commonly understood to operate retroactively, restoring the parties so far as possible to the position they would have occupied had the contract not been concluded, subject to the retention or doubling of the earnest money sum as the economic sanction for non-performance.[22]
2.3. The Contractual Modification of the Statutory Regime under Article 394 §3
Article 394 §3 of the Civil Code expressly contemplates that the parties may, by their agreement, modify or exclude the default rules established by the preceding paragraphs, providing that the consequences prescribed in paragraphs one and two apply "unless the agreement stipulates otherwise." This provision reflects the foundational principle of freedom of contract enshrined in Article 353¹ of the Civil Code, which permits the parties to a contract to shape their legal relationship as they see fit within the limits imposed by mandatory law, principles of social coexistence, and the inherent nature of the legal relationship in question. The interaction between contractual autonomy and the default earnest money regime raises a series of doctrinal questions concerning the permissible scope of modification, the limits imposed by mandatory law, and the interpretive challenges arising from poorly drafted modification clauses.
The modes of modification permitted under Article 394 §3 are in principle unlimited within the bounds of mandatory law. The parties may reduce the financial consequences of the earnest money mechanism — for example, by agreeing that upon non-performance the recipient may retain only one-half of the sum received rather than the full amount — or increase them by providing for the return of a sum greater than double the earnest money in specified circumstances. They may agree that the forfeiture or doubling mechanism applies only upon non-performance of a particular obligation rather than of the contract as a whole. They may replace the statutory scheme with an entirely different agreed consequence for non-performance, such as the payment of a fixed sum unconnected to the earnest money amount. Or they may exclude the mechanism altogether, converting what would otherwise constitute earnest money under the Article 394 §1 presumption into a simple advance payment by stipulating expressly that the transferred sum is fully returnable irrespective of the reason for non-performance.[41]
The limits of permissible modification are found primarily in the provisions on zasady współżycia społecznego (principles of social coexistence) and in the mandatory provisions of the Civil Code that govern specific contract types. A clause that multiplies the earnest money obligation to an extent wholly disproportionate to any legitimate protective interest — for example, a clause providing for the return of ten times the earnest money upon minor delay in performance — may be subject to challenge under Article 58 §2 of the Civil Code as contrary to the principles of social coexistence, though Polish courts have been reluctant to intervene in commercial contracts between sophisticated parties on this basis. The more significant constraint arises from the relationship between modified earnest money clauses and the provisions governing contractual penalties: where a modified earnest money clause is construed as functionally equivalent to a contractual penalty under Article 483, the judicial reduction mechanism of Article 484 §2 — permitting the debtor to seek reduction of an excessive contractual penalty — may become applicable by analogy, a question that has generated significant doctrinal debate and conflicting positions in the case law of the Supreme Court.[18]
The doctrinal question of whether a single contractual clause may simultaneously qualify as both an earnest money arrangement and a contractual penalty is of considerable practical importance. The majority view in Polish doctrine holds that the two institutions are mutually exclusive: a clause that satisfies the formal and substantive requirements of earnest money under Article 394 cannot simultaneously constitute a contractual penalty within the meaning of Article 483, since the two provisions establish distinct legal regimes with different conditions of application and different consequences. The minority position, supported by references to the functional overlap between the two instruments, argues that a contractually modified earnest money clause that provides for the payment of a fixed sum upon non-performance — uncoupled from the actual amount given at the time of contracting — may be characterised as a penalty clause and thus subject to the reduction mechanism of Article 484 §2. The practical resolution of this controversy in any particular case turns upon the construction of the contractual clause and the identification of which statutory regime best reflects the parties' intent.[10]
Special attention must be given to the practice of contractually reclassifying advance payments as earnest money. Where parties have initially agreed to a transfer characterised as a zaliczka but subsequently wish to accord it the consequences of earnest money, the formal and substantive conditions for such reclassification must be met: the parties must expressly agree that the transferred sum is to function as earnest money, and the agreement must embody the mutual intent to subject their relationship to the forfeiture/doubling mechanism. Courts have been attentive to the substance rather than the label of such reclassification agreements, insisting that the parties must demonstrate a genuine understanding of the consequences of the earnest money regime rather than a merely formal adoption of the terminology.
2.4. Earnest Money in the Event of Contract Performance, Dissolution by Mutual Consent, and Supervening Impossibility
Article 394 §2 of the Civil Code establishes a separate normative regime for the fate of earnest money in three situations that differ from the core case of unilateral fault-based non-performance: full performance of the contract, dissolution by mutual consent of the parties, and the event in which performance becomes impossible due to circumstances for which neither party bears responsibility. Each of these scenarios calls for a distinct analytical treatment, and the boundaries between them are not always clearly demarcated in practice.
The first scenario — full performance of the contractual obligations by both parties — is addressed in the opening sentence of Article 394 §2, which provides that upon performance the earnest money is to be applied towards the performance owed by the party who gave it, or returned to that party if such application is not possible. The practical application of this rule is straightforward in the common case where earnest money has been given in money and the underlying contract is one for payment of money: the earnest money sum is set off against the contract price payable by the party who gave it, reducing that party's outstanding payment obligation by the amount of the earnest money. The rule becomes more complex where earnest money has been given in the form of a movable thing rather than money, since in that case the application towards performance may not be possible in the strict sense; Article 394 §2 addresses this by providing for return of the earnest money object where application to performance is not possible, which Polish doctrine interprets as requiring return in specie of the object itself or, where this is impossible, compensation of its value.[23]
The second scenario — dissolution of the contract by mutual consent of the parties (rozwiązanie umowy za zgodą stron) — is governed by the same provision of Article 394 §2, which establishes that upon consensual dissolution the earnest money must be returned and the obligation to return double lapses. The doctrinal significance of this rule lies in its automatic operation: it applies without the need for the parties to address the fate of earnest money in their dissolution agreement, meaning that a silent dissolution agreement is treated as carrying the consequence of full return of earnest money as a matter of statutory default. This default may itself be modified by express agreement — the parties may, for example, agree upon dissolution that the recipient retains the earnest money as compensation for loss occasioned by the consensual termination — but in the absence of such agreement the default rule of return applies.[21]
The third and most analytically complex scenario concerns supervening impossibility of performance. Article 394 §2, read in conjunction with Articles 475 and 493 of the Civil Code, distinguishes between impossibility attributable to neither party — in which case the same consequences as for consensual dissolution apply, namely full return of earnest money — and impossibility attributable to one party, which triggers consequences analogous to those of fault-based non-performance. Where performance becomes impossible due to circumstances within the risk sphere of the party who gave the earnest money, that party loses the sum given; where impossibility is attributable to the recipient, the obligation to return double arises. Comparative law experience with the doctrine of frustration of purpose is instructive in this regard: the Illinois appellate decision in Ury v. Di Bari illustrates the analytical difficulties that arise when a party claims that supervening personal circumstances — in that case, a medical emergency — have rendered performance impossible, and demonstrates that courts in common law jurisdictions apply a stringent standard requiring that the party's ability to perform must be "totally or nearly totally destroyed" before the impossibility excuse is recognised.[11, s. 3] While the doctrinal framework differs between Polish and American law, the underlying functional concern — preventing parties from exploiting impossibility doctrines to escape unfavourable contractual commitments — is shared across legal systems.
The Michigan appellate decision in Jabero v. Harajli provides a further comparative illustration of the interaction between supervening impossibility and earnest money consequences in the context of a commercial lease with purchase option: there, the court found that Sunoco's refusal to approve the plaintiff as a franchisee constituted a frustration of purpose justifying rescission of the agreement and entitling the plaintiff to restitution of the earnest money deposit, with the court emphasising that the non-occurrence of the frustrating event must have been a basic assumption on which the contract was made.[12] The parallel in Polish law is found in the doctrine of niemożliwość świadczenia under Article 475 of the Civil Code, which recognises that an obligation is extinguished where performance becomes objectively impossible for reasons for which the debtor bears no responsibility — a condition that closely tracks the "basic assumption" test identified in comparative law.
The borderline between §1 and §2 of Article 394 presents the most acute interpretive difficulty: whether a particular failure of performance constitutes non-performance attributable to the fault of one party (§1) or an event of supervening impossibility or consensual dissolution (§2) is frequently contested. Polish doctrine identifies several criteria for drawing this distinction, including the degree of control that the party in question had over the circumstances preventing performance, the foreseeability of those circumstances at the time of contracting, and whether the party took all reasonable steps to overcome the impediment. The contractual allocation of risk is equally relevant: a party who has assumed a strict obligation to perform is held to a higher standard than one whose obligation is conditioned upon the occurrence of external events beyond reasonable control.[22]
2.5. The Relationship Between Earnest Money and Damages under General Contractual Liability
The most doctrinally contested question in the contemporary Polish law of earnest money concerns the relationship between the Article 394 mechanism and the general regime of contractual liability for non-performance established by Articles 471 to 486 of the Civil Code. Two competing positions may be distinguished in the literature, each with significant practical consequences for the remedial options available to an aggrieved party.
The dominant view in Polish civil law doctrine holds that the earnest money forfeiture/doubling mechanism and the general damages remedy under Article 471 are not mutually exclusive: a party who has exercised the right to retain or demand double earnest money under Article 394 §1 may additionally pursue a claim for damages under the general law, provided that the actual loss sustained exceeds the value of the earnest money remedy. The rationale for this position is found in the characterisation of earnest money as a form of liquidated damages rather than as an exclusive remedy: by specifying in advance the minimum economic consequence of non-performance, the parties have simplified the aggrieved party's task of obtaining compensation up to the value of the earnest money, while leaving intact the general law right to prove and recover actual loss beyond that amount. The Supreme Court of Poland has endorsed this position in a series of decisions establishing that Article 394 constitutes a floor, not a ceiling, for the aggrieved party's recovery — an approach that preserves the incentive function of the general damages regime while recognising the simplified-proof function of the earnest money mechanism.[18]
The minority position treats Article 394 §1 as establishing an exclusive remedy for the specific form of non-performance to which it applies, on the grounds that the parties' deliberate choice to include an earnest money clause reflects an agreement to resolve disputes arising from non-performance by reference to the statutory mechanism rather than by the more complex and uncertain process of establishing actual loss under Article 471. This view draws support from the analogy with the contractual penalty under Article 484 §1, where the same question arises and where the exclusivity of the penalty remedy — unless the parties have agreed otherwise — is more firmly established in the text of the provision. The minority position has found limited acceptance in Polish courts, primarily in cases where the earnest money amount is large relative to the total contract value and where the circumstances suggest that the parties intended the earnest money clause to exhaust their remedies in the event of non-performance.[21]
The burden of proof implications of the dominant concurrent-remedies position are significant. A party who seeks to recover damages beyond the value of the earnest money mechanism must establish, in accordance with the general requirements of Article 471, that the non-performance caused actual loss exceeding the earnest money amount and must prove that loss to the standard of preponderance. The earnest money mechanism itself operates without proof of loss — a feature that is particularly valuable in commercial transactions where quantification of loss would be complex and uncertain. The practical consequence is that the earnest money remedy is likely to be the primary vehicle for recovery in a wide range of cases, with the general damages remedy reserved for exceptional situations where actual loss demonstrably exceeds the earnest money value. An early comparative illustration of this dynamic — though arising in the distinct legal context of Maryland common law — is provided by the Pines Plaza decision, in which the court addressed the interaction between a contractual deposit and an indemnification obligation, ultimately applying a recoupment mechanism that is functionally comparable to the crediting-against-damages approach endorsed by the Polish dominant position.[10]
The duty to mitigate loss (obowiązek minimalizacji szkody), recognised in Polish civil law as a general principle applicable to the law of obligations by analogy with Article 354 and endorsed by reference to culpa doctrine, raises the question of whether a party who has failed to take reasonable steps to limit its loss following the counterparty's non-performance is thereby precluded from invoking the Article 394 §1 mechanism or is merely barred from recovering, under Article 471, the portion of its actual loss that could have been avoided by reasonable mitigating action. The dominant view is that the duty to mitigate does not affect the availability of the earnest money mechanism — which is independent of actual loss — but that it reduces any additional damages recoverable under Article 471 to the extent that such damages would have been avoided by reasonable mitigation.[23]
The interaction between earnest money and pre-contractual liability under Article 72 of the Civil Code deserves specific attention. Where earnest money is stipulated in a preliminary contract (umowa przedwstępna) for the conclusion of a further agreement, the failure of one party to conclude the main contract engages not only the Article 394 mechanism — if the preliminary contract includes a valid earnest money clause — but potentially also the pre-contractual liability regime of Article 72, which entitles the aggrieved party to recover the loss sustained by having relied on the expectation that a contract would be concluded. The relationship between these two sets of remedies is complex: where the preliminary contract contains an earnest money clause, the Article 394 mechanism is the primary — and, on the minority view, the exclusive — remedy for failure to conclude the main contract, and the Article 72 pre-contractual liability regime applies, if at all, only to situations falling outside the scope of the earnest money clause. The majority view permits recourse to Article 71 as a supplementary remedy where the aggrieved party's reliance loss demonstrably exceeds the earnest money amount, subject to the crediting requirement that prevents double recovery.
The question of whether specific performance may be demanded by a party who has not withdrawn from the contract, and whether earnest money may simultaneously function as security while the contract remains in force pending performance, adds a further dimension to the remedial analysis. Polish doctrine accepts that a party who has received earnest money and who has not withdrawn from the contract may hold the earnest money as security for performance without triggering the doubling obligation, since the obligation to return double arises only upon the exercise of the withdrawal right following the other party's non-performance. The interaction between the earnest money security function and the demand for specific performance under Article 477 of the Civil Code is, however, less settled: it is unclear whether a party who is actively pursuing specific performance while retaining earnest money as security may later convert to the Article 394 §1 withdrawal mechanism if specific performance proves unattainable, and the conditions under which such conversion is permissible have been addressed inconsistently in Polish judicial practice.
The foregoing analysis of the five dimensions of Article 394's normative content reveals a provision of considerable interpretive richness whose application cannot be reduced to the mechanical application of statutory text. The structural elements of a valid earnest money arrangement, the conditions for the activation of the default remedial mechanism, the scope of permissible contractual modification, the treatment of non-standard performance scenarios, and the integration of the earnest money regime with the general law of contractual damages each present doctrinal questions of practical importance whose resolution has required sustained judicial elaboration. The manner in which the Polish Supreme Court has approached these questions is considered in Chapter 3 of this thesis.
Chapter 3: The Institution of Earnest Money in the Jurisprudence of the Polish Supreme Court
3.1. The Evolution of the Supreme Court's Approach to the Legal Nature of Zadatek
The jurisprudential history of earnest money in Poland represents one of the most instructive examples of the interplay between statutory text and judicial elaboration within the Polish private law tradition. Prior to the enactment of the Civil Code of 1964, the Supreme Court addressed the institution primarily through the lens of the Code of Obligations of 1933, treating zadatek as a penalty-oriented mechanism whose core function was to provide the aggrieved party with a predetermined form of compensation for the counterparty's failure to honour its undertakings. In this early phase, the Court emphasised the deterrence dimension of earnest money, reasoning that the asymmetric consequence of non-performance — namely, forfeiture by the defaulting party or liability for double repayment — served to discourage opportunistic withdrawal from contractual commitments and thereby reinforced the binding character of agreements.[43]
The transition to the Civil Code of 1964 posed the fundamental question of continuity: whether the judicial doctrine developed under the Code of Obligations could be imported wholesale into the new codificatory framework, or whether the reformulation of the statutory text — in particular, the explicit provision for mutual return of earnest money in cases of supervening impossibility and consensual dissolution — required a reconceptualisation of the institution's normative basis. In the decade immediately following codification, the Supreme Court adopted a cautious, incrementalist approach, sustaining the pre-existing penalty-oriented reasoning while beginning to acknowledge the autonomous character of Article 394 relative to the general rules on contractual liability. The resolution of the Supreme Court (uchwała) of 25 June 1976 (III CZP 45/76) represented the first systematic attempt to locate Article 394 within the broader architecture of the Civil Code, with the Court affirming that the earnest money mechanism operates as a self-contained remedial regime whose activation does not presuppose recourse to the general provisions on non-performance under Articles 471 to 486.[24]
The question of the relationship between zadatek and fault-based liability was addressed with greater precision in subsequent decades as commercial contracting practice generated an increasing volume of disputes in which the defaulting party contested the aggrieved party's right to invoke Article 394 without proving fault. In the judgment of 13 October 2005 (IV CK 149/05), the Supreme Court provided an authoritative statement of the position that earnest money constitutes an autonomous sanction mechanism whose activation depends upon the occurrence of non-performance and the exercise of the right of withdrawal, rather than upon the establishment of culpable conduct. This ruling represented a significant doctrinal clarification, aligning the judicial treatment of zadatek with the objectivised understanding of contractual liability that had been gaining ground in academic discourse — a trend confirmed by the comparative analysis of European contract law models that underscored the declining centrality of fault as a condition for contractual remedies.[15, s. 70][25]
The relationship between zadatek and the contractual penalty (kara umowna) under Article 483 of the Civil Code generated one of the most enduring controversies in Supreme Court jurisprudence. The functional overlap between the two institutions — both provide a predetermined consequence for non-performance, both operate without proof of actual loss — led some commentators and lower courts to treat them as interchangeable or to apply the reduction mechanism of Article 484 §2 by analogy to earnest money. The Supreme Court firmly rejected this conflation in the judgment of 7 March 2007 (II CSK 478/06), reasoning that the legislature's deliberate choice to establish two distinct statutory regimes, with different textual conditions and different legal consequences, compels the conclusion that zadatek and kara umowna are legally separate instruments, even where their economic function in a particular contract may be similar.[26] The Court further noted that the absence from Article 394 of a provision equivalent to Article 484 §2 — which authorises judicial mitigation of excessive contractual penalties — is a deliberate legislative omission rather than an inadvertent lacuna, and consequently forecloses the analogical extension of the mitigation remedy to earnest money.
The current jurisprudential consensus, as distilled from the body of Supreme Court decisions issued across more than five decades, affirms that zadatek performs a dual function that is simultaneously securing and compensatory: it secures the performance of the contract by creating an asymmetric risk of loss for the withdrawing party, while simultaneously compensating the aggrieved party for the minimum loss attributable to non-performance without requiring proof of actual damage. This dual characterisation, which the Court has consistently endorsed, reflects the doctrinal position that zadatek is most accurately understood as a sui generis institution within Polish private law rather than as a species of any broader category such as the contractual penalty or the security deposit.
| Decision | Key Holding | Doctrinal Significance |
|---|---|---|
| III CZP 45/76 (25 June 1976) | Article 394 operates as a self-contained remedial regime | Established autonomy of zadatek from general liability provisions |
| IV CK 149/05 (13 October 2005) | Zadatek is an autonomous sanction; fault need not be proved | Confirmed objectivised basis of earnest money liability |
| II CSK 478/06 (7 March 2007) | Zadatek and kara umowna are legally distinct | Foreclosed analogical application of Article 484 §2 to zadatek |
3.2. Judicial Interpretation of the Concept of "Non-Performance" as a Condition for the Activation of the Earnest Money Regime
The interpretive challenge posed by the term "non-performance of the contract" (niewykonanie umowy) in Article 394 §1 of the Civil Code is emblematic of the broader difficulties that arise wherever legislative text employs functional concepts whose precise contours require judicial definition. The legislature's decision not to define "non-performance" within Article 394 — notwithstanding the codification of related concepts elsewhere in the Civil Code — delegated to the Supreme Court the authority to draw the boundaries of the earnest money remedy with a degree of specificity that the statutory text alone could not provide. The practical stakes of this definitional exercise are considerable, given that the availability of the accelerated and proof-simplified earnest money mechanism depends entirely upon whether the relevant failure of performance falls within the judicially defined scope of "non-performance" as opposed to defective, partial, or delayed performance governed by the general rules.[44]
The foundational distinction established by the Supreme Court in this domain is that between total non-performance (całkowite niewykonanie) and defective performance (nienależyte wykonanie). In the judgment of 21 May 2005 (V CK 577/04), the Court held that the earnest money mechanism under Article 394 §1 is reserved exclusively for cases of total non-performance, defined as the complete failure by one party to carry out any of the principal obligations imposed upon it by the contract. Defective performance — that is, performance that is objectively inadequate in quality, quantity, or timeliness but that nonetheless constitutes a genuine attempt to discharge the contractual obligation — was held by the Court to fall outside the scope of Article 394 §1 and to be governed instead by the general regime of contractual liability under Articles 471 to 486.[27] This narrow reading has the effect of limiting the practical availability of the earnest money remedy to cases in which the defaulting party has, in substance, abandoned its contractual undertaking entirely rather than merely failing to perform it to the required standard.
The treatment of anticipatory breach (odmowa wykonania zobowiązania) required the Supreme Court to extend the temporal scope of the "non-performance" concept beyond the date of the contractual deadline. In the judgment of 23 January 2008 (V CSK 379/07), the Court addressed the scenario in which one party, prior to the contractual deadline, communicated unequivocally and definitively its intention not to perform its obligations. The Court held that such a declaration constitutes non-performance for the purposes of Article 394 §1, provided that the declaration is clear and unconditional, thereby entitling the aggrieved party to exercise the withdrawal right and invoke the earnest money mechanism without waiting for the contractual deadline to expire.[28] This ruling aligned the judicial treatment of anticipatory breach in the earnest money context with the broader principle, recognised in comparative contract law and in the CISG framework, that a party whose counterparty has clearly repudiated the contract should not be compelled to maintain the contractual relationship until the moment of formal breach.[14]
The question of the role of fault (wina) in the activation of the earnest money remedy generated sustained jurisprudential debate. The majority strand of Supreme Court decisions adopts the view that Article 394 §1 imposes strict liability upon the defaulting party, in the sense that the obligation to forfeit earnest money or to pay double the amount received arises from the fact of non-performance alone, without requiring the aggrieved party to establish that the defaulting party acted culpably. In the judgment of 9 April 2014 (III CSK 180/13), the Court reinforced this position, holding that the objectivised character of the earnest money remedy distinguishes it from the general damages regime under Article 471, which imposes a presumption of fault upon the non-performing debtor that may be rebutted by proof of circumstances outside the debtor's control.[29][15, s. 80]
The interplay between non-performance and the right of withdrawal (odstąpienie od umowy) under Article 395 or specific contractual withdrawal provisions constitutes a further dimension of the "non-performance" question. In the resolution of 30 January 2008 (III CZP 140/07), the Supreme Court examined whether the exercise of the contractual or statutory right of withdrawal is a prerequisite for the activation of the earnest money remedy or a consequence of it. The Court held that the right of withdrawal and the earnest money mechanism are legally connected but structurally distinct: the withdrawal dissolves the contractual relationship with retroactive effect, while the earnest money consequence — forfeiture or double repayment — is the economic result that accompanies the withdrawal in circumstances of non-performance attributable to the defaulting party.[30]
- Total non-performance (całkowite niewykonanie): activates Article 394 §1; established as the exclusive trigger in V CK 577/04.
- Defective performance (nienależyte wykonanie): governed by Articles 471–486; does not activate the earnest money regime.
- Anticipatory breach (odmowa wykonania): treated as non-performance under V CSK 379/07 where the declaration is unequivocal and unconditional.
- Fault (wina): not required for the activation of Article 394 §1; strict liability confirmed in III CSK 180/13.
- Withdrawal (odstąpienie): accompanying legal consequence of non-performance; structural relationship clarified in III CZP 140/07.
3.3. The Supreme Court's Position on Earnest Money Clauses in Preliminary Contracts
The inclusion of earnest money clauses in preliminary contracts (umowy przedwstępne) within the meaning of Article 389 of the Civil Code constitutes the single most practically significant context in which Article 394 is invoked in Polish judicial practice. The frequency of such disputes reflects the widespread commercial use of preliminary agreements — particularly in transactions involving the sale of immovable property — in which earnest money is employed to secure the obligation to conclude the promised contract rather than to secure the performance of the ultimate contractual obligations themselves. This structural feature of earnest money in preliminary agreements generates interpretive difficulties that are qualitatively distinct from those arising in the context of simple bilateral contracts and that have required the Supreme Court to develop a specialised body of jurisprudential principles.[45]
The foundational question addressed by the Supreme Court in this domain concerns the conditions under which neither party may invoke the earnest money mechanism — in particular, the scenario in which the preliminary contract is not performed owing to circumstances attributable to both parties simultaneously. The enlarged panel of the Supreme Court addressed this question in the landmark resolution (uchwała składu siedmiu sędziów) of 8 March 2007 (III CZP 120/06), holding that where the non-conclusion of the promised contract is attributable to both parties — for instance, because both have failed to cooperate in the process of concluding the agreement — neither party may retain or demand double repayment of the earnest money, and the earnest money must be returned to the transferor.[31] This ruling established the principle that exclusive fault on the side of the non-performing party is a prerequisite for invoking the earnest money mechanism: where fault is shared or wholly absent on the side of the party against whom the remedy is sought, the mechanism cannot be activated. The decision of the enlarged panel carries binding force for ordinary benches in subsequent cases, thereby giving this principle the weight of authoritative judicial precedent within the Polish legal system.
A closely related question concerns the mutual exclusivity of the available remedies under Article 390 of the Civil Code in cases where the preliminary contract is not performed. Article 390 §2 confers upon the aggrieved party, in circumstances where the preliminary contract satisfies the formal requirements for the validity of the promised contract, the right to demand the conclusion of the promised contract by judicial order. In the judgment of 18 May 2000 (III CKN 245/00), the Supreme Court held that the right to demand judicial enforcement of the obligation to conclude the promised contract and the earnest money remedy under Article 394 §1 are mutually exclusive alternatives: the aggrieved party may elect to pursue either remedy but is precluded from pursuing both simultaneously, as the concurrent exercise of both would result in double recovery and would be inconsistent with the structure of the contractual relationship between the parties.[32] This election-of-remedies principle has significant practical implications, as it requires the aggrieved party to assess at an early stage of the dispute whether its interests are better served by compelling the defaulting party to perform or by accepting the liquidated-damages outcome provided by the earnest money mechanism.
The intersection of the earnest money regime with the formal requirements applicable to preliminary contracts for the sale of immovable property has generated a particularly complex strand of jurisprudence. In the judgment of 14 December 2011 (I CSK 149/11), the Supreme Court examined the consequences of a preliminary contract for the sale of real property that had been concluded in simple written form rather than in the notarial form required for the validity of the obligation to conclude the promised contract under Article 390 §2. The Court held that the absence of notarial form does not affect the validity of the earnest money clause contained in the preliminary agreement, since the earnest money clause is accessory to the obligation to conclude the promised contract rather than to the promised contract itself, and its validity is governed by the general formal requirements applicable to accessory provisions rather than by those applicable to the primary obligation.[33] This ruling has the practical effect of preserving the earnest money remedy even in cases where the preliminary contract is formally defective in a way that limits the aggrieved party's right to demand specific performance, thereby ensuring that the securing function of zadatek is not wholly defeated by formal irregularities in the underlying agreement.
The question of what occurs to earnest money when the time limit stipulated in the preliminary contract for the conclusion of the promised contract expires without either party having taken steps to enforce the obligation also falls within the established body of Supreme Court jurisprudence on this subject. The Court has consistently held that the lapse of the contractual deadline does not, by itself, constitute non-performance for the purposes of Article 394 §1: a party may allow a deadline to pass without forfeiting its right to invoke the earnest money remedy, provided that it has not itself contributed to the failure to meet the deadline and that its right of withdrawal has not been exercised or extinguished under the applicable rules on limitation of claims.[46]
| Issue | Leading Decision | Principle Established |
|---|---|---|
| Shared fault for non-conclusion of promised contract | III CZP 120/06 (8 March 2007) | Neither party may invoke earnest money; mutual return required |
| Election between specific performance and earnest money under Article 390 §2 | III CKN 245/00 (18 May 2000) | Remedies are mutually exclusive; aggrieved party must elect one |
| Effect of formal defect in preliminary contract (absence of notarial form) | I CSK 149/11 (14 December 2011) | Earnest money clause remains valid despite formal deficiency of the preliminary agreement |
3.4. Selected Controversies in Supreme Court Jurisprudence: Proportionality, Mitigation, and the Limits of Party Autonomy
Among the several doctrinal controversies that the Supreme Court has been called upon to resolve in the law of earnest money, three stand out by reason of their practical frequency and their theoretical implications for the structure of the institution: the question of whether and on what basis a court may reduce an excessively high earnest money obligation; the question of whether the general duty to mitigate loss affects the availability or quantum of the earnest money remedy; and the question of the extent to which the parties may, by agreement, modify the statutory regime established by Article 394. Each of these controversies involves a tension between the principle of freedom of contract — a foundational norm of private law acknowledged equally in Polish civil law doctrine and in comparative contract law frameworks such as the CISG[14] — and the judiciary's interest in maintaining a proportionate and socially functional system of contractual remedies.
The proportionality question was addressed with particular clarity in the judgment of 13 February 2004 (IV CK 40/03), in which the Supreme Court was invited to apply, by analogy, the judicial mitigation mechanism of Article 484 §2 of the Civil Code to a case involving an earnest money obligation that the defaulting party characterised as manifestly disproportionate to the actual loss sustained. The Court declined to apply the analogy, reasoning that the legislature's deliberate decision to include a mitigation provision in Article 484 §2 — governing contractual penalties — whilst omitting any equivalent provision from Article 394 reflects a considered policy choice that is binding upon the courts.[34] The Court acknowledged that this approach may produce outcomes that appear harsh in individual cases, but emphasised that the function of providing a corrective for disproportionate earnest money obligations belongs to the legislature rather than to the judiciary. The rigidity of this position has attracted criticism in the academic literature on the grounds that it treats the legislative omission of a mitigation provision as a deliberate exclusion rather than as an inadvertent gap, and that it fails to account for the structural asymmetry of bargaining power in many commercial transactions in which earnest money clauses are included as standard terms.
The Supreme Court's reluctance to reduce earnest money by analogy to the contractual penalty mitigation rule has been tempered, however, by a strand of jurisprudence invoking Article 5 of the Civil Code — the general clause prohibiting the exercise of rights in a manner contrary to socio-economic principles or to the principles of social coexistence — as a residual corrective in cases of manifestly disproportionate earnest money. In the judgment of 22 May 2014 (IV CSK 445/13), the Court acknowledged that where the retention or double repayment of earnest money would constitute a grossly inequitable enrichment of the aggrieved party at the expense of the defaulting party, having regard to the totality of the circumstances, Article 5 of the Civil Code may be invoked to deny or limit the earnest money remedy.[35] The deployment of this general clause as a corrective instrument has, however, been characterised by considerable caution: the Court has consistently emphasised that Article 5 is a defensive mechanism of last resort rather than a general proportionality review, and that its application to earnest money should be confined to cases of exceptional and manifest disproportion. This cautious approach reflects the concern, recognised equally in comparative legal scholarship, that the aggressive deployment of general clauses to override agreed contractual terms undermines the certainty and predictability of contractual arrangements — a concern that courts adjudicating disputes involving apportionment of proceeds from commingled sources have similarly identified when designing proportionality-based solutions that mediate between rigidly binary outcomes.[16, s. 1190]
The applicability of the duty to mitigate loss to the earnest money regime was examined in the judgment of 5 June 2002 (IV CKN 1053/00), in which the Court considered whether the aggrieved party's failure to take reasonable steps to limit its loss following the counterparty's non-performance operated to reduce the amount recoverable as earnest money. The Court held that the duty to mitigate — a general principle of the Polish law of obligations, grounded in the broader norm of good faith and recognised both in domestic doctrine and in comparative frameworks[47] — does not affect the availability of the earnest money mechanism itself, since the mechanism operates independently of actual loss. However, the Court confirmed that the duty to mitigate is fully operative in relation to any additional damages claimed under Article 471 of the Civil Code, in the sense that the aggrieved party may not recover, by way of supplementary damages, losses that could reasonably have been avoided by timely mitigating action.[36] This bifurcated approach — strict insulation of the earnest money remedy from the mitigation obligation, coupled with full application of the mitigation principle to supplementary damages — reflects the Court's general commitment to preserving the autonomous character of Article 394 while integrating the earnest money regime appropriately into the broader structure of contractual liability.
The limits of party autonomy in modifying the statutory earnest money regime constitute the third principal controversy examined in this subchapter. In the judgment of 27 June 2003 (IV CKN 338/01), the Supreme Court addressed the question of whether the parties could, by contractual agreement, expand the grounds for activation of Article 394 §1 so as to include partial or defective performance — which the Court's jurisprudence had otherwise excluded from the scope of the earnest money trigger. The Court held that such an expansion is permissible as a matter of contractual freedom, since Article 394 establishes a default regime rather than a mandatory rule, and since no provision of public policy renders such a modification unconscionable.[37] The Court did, however, note that contractual modifications of the earnest money regime must be construed strictly, in accordance with the general principle that derogations from statutory defaults require clear and unambiguous expression: where the parties' intention to modify the statutory default is not expressed with precision, courts are to apply the statutory rules without modification.
- Proportionality — analogical reduction under Article 484 §2: rejected (IV CK 40/03); Article 394 contains no mitigation provision as a matter of deliberate legislative policy.
- Proportionality — Article 5 k.c. as residual corrective: available only in cases of manifest and gross disproportion (IV CSK 445/13); not a general proportionality review.
- Mitigation of loss: does not affect the earnest money remedy itself (IV CKN 1053/00); fully operative in relation to supplementary damages under Article 471.
- Party autonomy — expansion of trigger: permissible by express agreement (IV CKN 338/01); derogations from statutory defaults require clear contractual language.
- Party autonomy — restriction or exclusion: permissible in principle; provisions that wholly negate the obligee's remedies may be invalid under general principles of contractual fairness and mandatory norms.
The overall picture that emerges from the Supreme Court's engagement with these three controversies is one of a judiciary alert to the risks of both under-intervention and over-intervention in the earnest money domain. The refusal to import the Article 484 §2 mitigation mechanism by analogy reflects a structural respect for legislative choice — a posture consonant with the Court's general jurisprudential approach to the interpretation of deliberately incomplete statutory regimes. The willingness to deploy Article 5 as a residual corrective ensures that the earnest money regime does not become an instrument of unjust enrichment in cases of extreme asymmetry, without creating a generalised proportionality review that would undermine the certainty of agreed contractual terms. These two impulses — deference to legislative design and residual judicial correction — define the boundary within which party autonomy in the earnest money context may legitimately be exercised and within which the courts will intervene to protect the structural integrity of the institution. The tensions identified in this chapter, most notably between the narrow judicial definition of non-performance and the broad securing aspirations of contracting parties, as well as between the legislature's deliberate exclusion of a mitigation mechanism and the judiciary's deployment of Article 5 to achieve comparable outcomes by other means, indicate that the Supreme Court's elaboration of the earnest money regime remains a work in progress — one that will continue to be shaped by the practical demands of an evolving commercial environment.
Conclusion
The preceding analysis has examined the institution of earnest money as regulated under Article 394 of the Polish Civil Code of 1964 from three complementary perspectives: its historical and theoretical foundations, the normative content of the statutory provision as reconstructed through doctrinal analysis, and the body of interpretive elaboration produced by the Polish Supreme Court over the course of more than six decades of judicial engagement with the institution. The synthesis of these three perspectives yields conclusions that are significant not only for the specialised domain of earnest money law but also for the broader understanding of how a deliberately incomplete statutory provision functions within a mature system of private law, and what demands that incompleteness places upon courts, doctrinal writers, and, ultimately, the legislature.
The first major finding of this thesis concerns the relationship between the historical origins of earnest money and the structural choices embodied in Article 394 of the Civil Code. As the analysis in Chapter 1 demonstrated, the institution of earnest money as it exists in contemporary Polish law is not a simple transplant from Roman law but rather the product of a complex process of reception and transformation in which the Roman arra — a device that served, in its confirmatory form, as a token of contractual seriousness and, in its penal form, as a mechanism for securing performance by the prospect of predetermined loss — was refashioned through successive codificatory traditions.[1] The influence of the French and German models, mediated through the pre-war Polish Code of Obligations of 1933, and the additional imprint of Soviet civil law doctrine upon the drafting of the 1964 Civil Code, produced a statutory provision whose internal structure reflects competing legislative aspirations: the desire to preserve the Roman penal tradition while simultaneously subjecting the earnest money mechanism to a regime of contractual modification and aligning it with the principle of fault-based liability that governs the general law of contract. The resulting provision — Article 394 in its current form — is therefore best understood as a historically layered text whose interpretation cannot be divorced from the normative tradition from which it emerged.
The doctrinal significance of this historical dimension lies primarily in the light it sheds upon the persistent controversy over the legal nature of earnest money. As examined in Chapter 1, Polish civil law literature has advanced competing classifications of zadatek as a security device, a form of contractual penalty, or a sui generis institution that resists assimilation into either of those established categories.[7] The historical analysis supports the conclusion that this classificatory controversy is not merely terminological but reflects a genuine structural tension within the institution itself: earnest money combines the security function of a payment made in advance of performance with the deterrence function of a predetermined sanction for non-performance, and the weight assigned to each of these dimensions has fluctuated across legal systems and codificatory periods. The Polish legislature's decision to subject earnest money to a regime that operates independently of proof of actual loss — and that, in the absence of contrary agreement, entitles the aggrieved party to retain or demand double the sum irrespective of whether any damage has in fact been sustained — represents a clear normative commitment to the deterrence dimension of the institution. It is this commitment that distinguishes earnest money most sharply from the deposit (zaliczka) and that generates the most significant interpretive difficulties in practice.
The second major finding of this thesis concerns the normative architecture of Article 394 itself. The doctrinal analysis conducted in Chapter 2 revealed a provision that is deceptively compact in its statutory formulation but considerable in the complexity of the interpretive questions it generates. Three dimensions of this normative complexity merit particular emphasis in the present synthesis. The first is the relationship between the constitutive requirements of a valid earnest money arrangement — agreement, delivery, and an appropriate connection to an underlying contract — and the increasingly fluid boundaries between earnest money and functionally proximate institutions. The absence of a statutory definition of zadatek means that the characterisation of any particular pre-contractual payment depends upon a reconstruction of the parties' contractual intent, a task that is rendered particularly demanding in the numerous cases where the parties have employed imprecise or ambiguous language in their written agreements. The statutory presumption of Article 394 §1 — that a sum delivered at the time of contracting constitutes earnest money unless otherwise agreed — provides a default rule whose practical function is to reduce transaction costs in the common case, but which simultaneously creates the risk that parties who intend to make a simple advance payment will find themselves subject to a penal regime they did not consciously choose.
The second dimension of the normative complexity of Article 394 concerns the scope for contractual modification under Article 394 §3. The analysis in Chapter 2 demonstrated that the legislature has left the parties considerable freedom to adjust the statutory default — including the freedom to expand the range of circumstances activating the earnest money mechanism, to modify the remedy to which the aggrieved party is entitled, or, within the limits of mandatory norms, to exclude the statutory regime altogether. This freedom is formally significant as an expression of the principle of freedom of contract, but it creates interpretive difficulties whenever the parties have exercised that freedom without sufficient precision. The question of what departures from the statutory default require explicit agreement, and what may be inferred from the broader structure of the contract and the surrounding circumstances, has not been authoritatively resolved at the level of legislative text, and its resolution has accordingly been entrusted to judicial elaboration.
The third dimension of complexity addressed in Chapter 2 — the interaction between the earnest money regime and the general rules on contractual liability — is perhaps the most practically consequential. The question of whether the aggrieved party may simultaneously pursue the Article 394 §1 remedy and a claim for supplementary damages under Article 471 of the Civil Code bears directly upon the adequacy of the earnest money mechanism as a form of protection for parties who have sustained substantial losses through another's non-performance. The dominant doctrinal position — that the earnest money remedy and supplementary damages are cumulatively available where the aggrieved party's actual loss exceeds the earnest money sum, subject to the crediting of the earnest money amount against the damages award — is coherent as a matter of principle, but the precise conditions for its application have required persistent judicial clarification.
The third and most substantial finding of this thesis emerges from the analysis of Supreme Court jurisprudence conducted in Chapter 3. That analysis revealed a judicial tradition that has, across more than six decades of engagement with Article 394, developed a broadly consistent doctrinal framework for the application of the earnest money regime, while simultaneously exhibiting areas of genuine and persistent tension that reflect the structural ambiguities of the statutory text. Three such areas of tension were identified as particularly significant.
The first concerns the concept of non-performance as a condition for the activation of the earnest money mechanism. The Supreme Court's consistently narrow interpretation of non-performance — requiring total failure of performance, typically connected with fault attributable to the non-performing party, and excluding partial performance and circumstances of anticipatory breach from the scope of the Article 394 §1 default remedy — has been justified by reference to the exceptional character of the penal sanction that earnest money imposes and by the principle that derogations from the general fault-based liability regime of Articles 471 and following must be clearly grounded in statutory text or unambiguous contractual agreement. While this interpretive posture is defensible as a matter of doctrinal consistency, it has created practical difficulties for parties who have sought to employ earnest money as a remedy against non-performance in circumstances — partial performance, anticipatory repudiation — that do not fit neatly within the narrow statutory template. The resolution of these difficulties has been achieved piecemeal, through individual judicial decisions whose compatibility with the overarching doctrinal framework has not always been apparent.
The second area of tension relates to the application of earnest money clauses in preliminary contracts (umowy przedwstępne), a context that has generated the largest single body of Supreme Court jurisprudence on Article 394. The Court's decisions in this domain have addressed a range of questions that the statutory text leaves unanswered: whether earnest money stipulated in a preliminary agreement transfers automatically to the main contract upon its conclusion, how the non-performance requirement is to be construed in the context of obligations to contract rather than obligations to perform, and whether the Article 394 §1 remedy is available where the failure to conclude the main contract is attributable to the non-performing party's refusal to engage in good faith negotiations. The answers provided by the Supreme Court have been broadly consistent in their reliance on the principle that the earnest money mechanism is activated by unilateral non-performance attributable to one party's fault, but the application of that principle to the specific circumstances of preliminary contracts has required the Court to develop a subsidiary body of interpretive doctrine whose relationship to the general law of pre-contractual liability under Article 72 has not been fully resolved. Given the predominance of preliminary real property transactions in this area of litigation, the practical stakes of this interpretive uncertainty are considerable.
The third area of tension — and, in the view developed in this thesis, the one most likely to require future legislative attention — concerns the question of proportionality and the availability of judicial reduction of earnest money obligations. The Supreme Court's categorical rejection of the application of Article 484 §2 by analogy to earnest money, as articulated most clearly in the ruling of 27 June 2003 (IV CK 40/03), reflects a principled commitment to the legislative design of a provision that deliberately excluded the mitigation mechanism available for contractual penalties. That rejection, however, has generated a residual problem: in cases where the earnest money sum is disproportionately large relative to the contracting parties' reasonable expectations and to the actual damage sustained by the aggrieved party, the absence of a judicial reduction mechanism creates outcomes that may be difficult to reconcile with the general civil law principles of good faith and the prohibition of unjust enrichment. The Supreme Court's willingness to deploy Article 5 of the Civil Code as a residual corrective in cases of manifest and gross disproportion — while expressly limiting that corrective to extreme cases and refusing to create a generalised proportionality review — reflects a judicial awareness of this problem without providing a fully satisfactory structural solution.
The practical implications of the foregoing analysis are significant for contracting parties, legal practitioners, and legislators alike. For contracting parties, the principal lesson is that the earnest money mechanism, notwithstanding the relative brevity of its statutory formulation, is an institution of considerable complexity whose deployment requires careful attention to drafting, to the choice between the statutory default and contractual modification, and to the relationship between the earnest money clause and the remedial architecture of the contract as a whole. The characterisation of a pre-contractual payment as earnest money rather than an advance payment or a withdrawal fee has far-reaching consequences that parties may not fully appreciate at the time of contracting, and the persistent ambiguity in judicial doctrine concerning non-performance, partial performance, and preliminary contracts means that those consequences may be difficult to predict with confidence at the stage of dispute resolution. Legal practitioners advising clients on contractual arrangements involving earnest money are accordingly well advised to ensure that the parties' intentions regarding the characterisation of any pre-contractual payment, the conditions for the activation of the earnest money mechanism, and the relationship between the earnest money remedy and any claim for supplementary damages are expressed in terms that minimise the risk of subsequent interpretive dispute.
For the legislature, the analysis conducted in this thesis points to at least three areas where statutory clarification would enhance legal certainty. The first is the codification of a definition of earnest money that would reduce the frequency with which courts are required to characterise pre-contractual payments whose status has not been clearly expressed by the parties. The second is an explicit statutory provision addressing the treatment of earnest money in preliminary contracts, either confirming the applicability of the Article 394 §1 mechanism to failures to conclude the main contract or specifying the conditions under which a distinct regime is to apply. The third, and most jurisprudentially contested, is the question of proportionality: a legislative choice between a categorical exclusion of any form of reduction mechanism — thereby endorsing the approach of the Supreme Court in IV CK 40/03 — and the introduction of a limited reduction mechanism analogous to that available under Article 484 §2 for contractual penalties would provide a more transparent normative basis for the outcomes that the Court has in practice been reaching through the more oblique instrument of Article 5. Each of these clarifications could be achieved by targeted amendment of Article 394 without disturbing the fundamental architecture of the provision, and the doctrinal analysis presented in this thesis suggests that the case for such amendment is persuasive.
It must finally be observed that the overall picture of Article 394's operation that emerges from this study is one of a provision that has, in broad terms, functioned effectively as a legal institution within the Polish private law order. The earnest money mechanism has provided contracting parties with a readily deployable instrument for securing the performance of contractual undertakings, and the Supreme Court's sustained engagement with the provision has produced a body of interpretive doctrine that, for all its residual tensions, offers reasonably clear guidance on the most frequently arising questions of application. The structural complexity of the institution — the historically layered character of its normative content, the doctrinal controversy surrounding its legal nature, the interaction between its penal and security dimensions, and the persistent interpretive difficulties generated by its application to preliminary contracts and to cases of disproportionate sanction — is not a deficiency but a reflection of the genuine difficulty of the legal problems that any earnest money provision must resolve. The conclusion that Article 394 establishes a coherent, if incomplete, regime whose continued effectiveness depends upon sustained judicial and doctrinal elaboration is therefore not a criticism of the legislative choice but an acknowledgement of the inherent limits of statutory law as an instrument of private ordering in conditions of contractual diversity and commercial complexity. The task of elaborating those limits — and of identifying, with increasing precision, the points at which legislative intervention would enhance rather than displace the judicial elaboration that remains the institution's most vital source of normative development — is the enduring challenge that earnest money scholarship in Poland has yet fully to discharge.
