A Western European creditor holds a final arbitral award against a Polish subsidiary. The award was rendered by an arbitral tribunal seated in Vienna under ICC Rules. The creditor's counsel now faces a system that is simultaneously familiar – Poland is an EU Member State and a signatory to the New York Convention – and deceptively complex in its procedural detail. What appears to be a straightforward enforcement exercise can stall at the regional court level for reasons that have nothing to do with the merits of the underlying dispute.
Cross-border enforcement in Poland operates through two parallel channels: recognition and enforcement of foreign court judgments under EU instruments and bilateral treaty mechanisms. Additionally. Enforcement of foreign arbitral awards under the New York Convention framework, implemented through Polish civil procedure legislation. The competent first-instance court for both channels is the regional court (sąd okręgowy). With appeals directed to the court of appeal (sąd apelacyjny) and, on points of law, to the Sąd Najwyższy (Supreme Court of Poland). Timelines at first instance range from six months to over eighteen months, depending on the complexity of the challenge mounted by the respondent.
This analysis examines the doctrinal foundations of the Polish enforcement system, the gap between the statutory text and actual court practice, the role of the seat of arbitration and institutional rules. The strategic choices available to international claimants. Additionally, the regulatory trajectory practitioners should monitor in the years ahead.
Doctrinal foundations: where civil law tradition meets international obligations
Poland's approach to cross-border enforcement is rooted in its civil law tradition. The country inherited a codified procedural system that draws heavily on continental European models. At the same time, Poland's accession to the EU and its longstanding participation in multilateral treaty regimes have layered international obligations over that domestic foundation.
For judgments originating within the EU, the applicable regime is the Brussels I recast regulation. This instrument largely abolishes the need for a separate exequatur procedure among EU Member States for civil and commercial matters. A judgment creditor can, in most cases, present an EU-issued certificate alongside the judgment itself and proceed directly to enforcement through the Polish enforcement officer (komornik sądowy). In practice, however, the komornik's role begins only after the judgment has been rendered enforceable in procedural terms. Where a respondent challenges enforcement on the limited grounds available under the regulation – public policy, irreconcilable judgments, or breach of procedural rights – the matter returns to the sąd okręgowy for a substantive ruling.
For judgments originating outside the EU. from the United Kingdom post-Brexit, from the United States, or from jurisdictions without a bilateral enforcement treaty. the creditor must pursue full recognition proceedings under Polish civil procedure rules. This is a more demanding process. The court examines jurisdiction, finality, procedural fairness, and public policy compliance. It does not re-examine the merits, but the scope of review is broader than under the Brussels I regime. Practitioners working on UK-origin judgments since Brexit have encountered this additional layer with increasing frequency.
For arbitral awards, the doctrinal foundation is the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, to which Poland has been a party for decades. Polish civil procedure legislation incorporates the Convention's framework directly. The grounds for refusal mirror those in the Convention: invalidity of the arbitration agreement, breach of due process. Excess of jurisdiction by the arbitral tribunal, procedural irregularities at the seat of arbitration, non-finality of the award, and public policy. The Sąd Najwyższy has consistently held that these grounds must be interpreted narrowly. The court is not an appellate body over the arbitral process.
This dual-channel system creates a strategic choice for international claimants from the outset. Where a claim could be pursued through either litigation in an EU court or arbitration with a seat inside or outside the EU. The enforcement destination. Poland, in this case. should inform the choice of dispute resolution mechanism at the contract drafting stage. Many international parties overlook this consideration entirely until a dispute has already crystallised.
Court practice and the gap between statute and enforcement reality
Polish civil procedure legislation governing arbitration and foreign judgment enforcement is, on its face, well-aligned with international standards. The award enforcement provisions closely track the UNCITRAL Model Law in structure and intent. The public policy exception is explicitly confined to fundamental principles. Yet the gap between the statutory text and the lived experience of enforcement proceedings is real and consequential.
The first gap concerns procedural formality. Polish courts apply strict documentary requirements. An application to enforce a foreign arbitral award must be accompanied by the original award or a certified copy, a certified copy of the arbitration agreement, and certified translations of both documents into Polish. A failure to meet any of these requirements does not typically result in immediate dismissal, but it triggers a formal deficiency notice and a short cure period. Missing that cure period – often as short as one week – can result in the application being returned without substantive review. International creditors who manage the process from abroad without local counsel regularly encounter this obstacle.
The second gap concerns the treatment of procedural challenges mounted by respondents. Polish civil procedure rules permit a respondent to challenge enforcement on all Convention grounds. In practice, the public policy defence is raised in the overwhelming majority of contested enforcement proceedings. Polish courts have, over time, developed a reasonably consistent line of authority holding that this defence does not permit a re-examination of the merits. The Sąd Najwyższy has repeatedly affirmed this position. However, first-instance courts do not always apply the standard with the same rigour. A small but significant share of first-instance decisions have accepted public policy arguments that appellate courts subsequently rejected. This creates the risk of a successful first-instance challenge that delays enforcement by twelve to eighteen additional months during the appeal process.
The third gap relates to the treatment of interim measures. Polish civil procedure rules allow a creditor to apply for a zabezpieczenie (interim security order) in parallel with or in advance of enforcement proceedings. This is a powerful tool. If granted, it freezes the respondent's assets pending the outcome of the enforcement application. However, the threshold for obtaining a zabezpieczenie is not trivial. The applicant must demonstrate both a credible legal basis for the claim and a genuine risk that the respondent will dissipate assets before enforcement is complete. Courts assess the second criterion cautiously. Evidence of asset dissipation – such as recent transfers to related parties, unusual dividend distributions, or unexplained reductions in balance-sheet assets – materially strengthens the application.
The fourth gap concerns the enforcement of awards rendered by an arbitral tribunal seated outside common law jurisdictions. Polish courts are generally comfortable with awards from ICC, LCIA, and UNCITRAL proceedings. Awards from less familiar institutional contexts – particularly those from Central Asian or CIS-based arbitration centres – attract more scrutiny at the document verification stage. Courts have occasionally questioned the authenticity of awards and required additional apostille certification even where the Convention does not strictly require it. Practitioners should anticipate this and build the evidentiary record accordingly.
For businesses engaged in litigation and arbitration in Poland, understanding these procedural gaps before commencing enforcement proceedings is as important as understanding the substantive legal grounds for refusal. The procedural risks are addressable; they simply require advance planning.
Treaty architecture: New York Convention, bilateral instruments and EU regulation
Poland's treaty architecture for cross-border enforcement is layered and occasionally overlapping. Each layer carries its own procedural logic and its own exceptions.
The New York Convention remains the primary instrument for award enforcement. Poland acceded with a reciprocity reservation, meaning that Polish courts will apply the Convention to awards made in other contracting states. The reservation has practical consequences. Where a creditor seeks to enforce an award made in a non-contracting state, the domestic civil procedure rules apply instead. Those rules are somewhat less predictable in their application, and the grounds for refusal are slightly broader.
Within the EU, the Brussels I recast regulation governs the mutual recognition of court judgments in civil and commercial matters. For enforcement of EU court judgments in Poland, the process is streamlined to the point where the principal risk is no longer substantive but procedural. ensuring the required certificate is in order. The translation is complete. Additionally, the enforcement officer has the correct documentation. Disputes about jurisdiction and public policy under the regulation are uncommon but do arise in cases involving consumer contracts, insurance, or exclusive jurisdiction clauses.
Poland is also party to a network of bilateral enforcement treaties with a range of states, including several former Soviet bloc countries and some Middle Eastern jurisdictions. These bilateral instruments predate EU accession and, where they overlap with the Brussels I regulation, EU law takes precedence within the EU context. For enforcement involving non-EU states, however, the bilateral treaties remain directly relevant. Their procedural requirements vary considerably. Some require full exequatur proceedings; others establish lighter-touch administrative mechanisms. Identifying the applicable treaty – and whether it has been supplemented or superseded by subsequent multilateral arrangements – is a preliminary step that should not be skipped.
The Energy Charter Treaty deserves separate mention in the Polish context. Poland is a contracting party to the ECT, which provides investor-state arbitration rights for investments in the energy sector. ECT arbitrations involving Polish state entities or regulatory measures have generated a series of significant awards in recent years. The enforcement of those awards against Polish state assets raises questions that go beyond ordinary commercial enforcement. involving issues of state immunity. Sovereign assets. Additionally, the ongoing EU internal market compatibility debate surrounding intra-EU ECT claims. This is a distinct and technically complex subset of the enforcement landscape.
For parties with enforcement scenarios spanning multiple EU jurisdictions, the comparison with other civil law systems is instructive. Our analysis of cross-border enforcement in Portugal illustrates how a similarly structured civil law system applies the New York Convention and Brussels I regulation in ways that differ at the procedural detail level. Even where the substantive doctrine is aligned.
Seat of arbitration, institutional rules and strategic structuring
The choice of seat of arbitration matters enormously for enforcement in Poland. This is a point that experienced practitioners emphasise but that many contracting parties discover only after a dispute has arisen.
The seat of arbitration determines the lex arbitri. the national arbitration legislation that governs the conduct of the proceedings. The validity of the arbitration agreement. Additionally, the grounds on which an award may be set aside at the seat. An award set aside at the seat is, under the New York Convention, a ground for refusal of enforcement in Poland. Courts in Poland are not required to refuse enforcement of a set-aside award. the Convention uses permissive language. but in practice. Polish courts treat a final annulment at the seat as a strong indicator against enforcement. A partial annulment creates more room for argument.
Where the seat of arbitration is within the EU, parties benefit from the additional assurance that the supervisory court operates within a rule-of-law system subject to EU judicial standards. Where the seat is in a jurisdiction with a less developed arbitration legislative regime, the risk of procedural complications at the set-aside stage increases. Choosing a well-established seat – London, Paris, Vienna, Geneva, Stockholm, or Warsaw itself – reduces that risk materially.
Warsaw has emerged as a credible seat for Central and Eastern European disputes. The Sąd Arbitrażowy przy Krajowej Izbie Gospodarczej (Court of Arbitration at the Polish Chamber of Commerce) is the principal institutional venue. Its procedural rules have been updated to reflect modern international practice, and its awards benefit from the full New York Convention enforcement network. For disputes with a predominantly Polish or CEE dimension, a Warsaw seat combines procedural efficiency with straightforward enforcement locally.
The choice of institutional rules – ICC Rules, UNCITRAL rules, LCIA rules, or the rules of a local institution – interacts with the seat question but is legally distinct. Polish courts are familiar with ICC and UNCITRAL proceedings and apply no additional scrutiny to awards rendered under those rules. Practitioners have noted that awards issued under less familiar institutional rules occasionally require additional explanation at the recognition stage. This is not a formal legal obstacle, but it adds procedural friction.
One underappreciated strategic option is the use of a multi-tiered dispute resolution clause that combines escalation through negotiation and mediation with a final binding arbitration step. Polish courts have upheld the enforcement of awards rendered under such clauses, provided the escalation steps were either followed or demonstrably waived. The risk arises where a party argues that the pre-arbitration conditions were not met. A well-drafted clause with clear timelines and deemed-waiver provisions substantially reduces that risk.
For corporate disputes that may involve Polish entities in a broader restructuring or insolvency context, the interaction between arbitration and insolvency legislation deserves attention. Polish insolvency legislation suspends ongoing arbitration proceedings upon declaration of insolvency and routes claims through the insolvency estate mechanism. An arbitral award obtained after the insolvency opening date may not be directly enforceable in the ordinary way. Creditors facing this scenario should seek specialist advice on the intersection of these two legislative regimes. An overview of the related issues is available in our analysis of corporate disputes in Poland.
Strategic recommendations for international claimants
International parties pursuing or defending enforcement proceedings in Poland benefit from a structured approach that anticipates the procedural gaps described above and deploys the available legal instruments in the right sequence.
At the contract drafting stage, the most valuable intervention is a carefully designed dispute resolution clause. The clause should specify: the seat of arbitration, the institutional rules, the language of proceedings, the number of arbitrators, and – critically – the governing law of the arbitration agreement itself. The last point is frequently omitted. Where the governing law of the main contract differs from the law of the seat, ambiguity about the validity of the arbitration agreement can generate a jurisdictional challenge that delays enforcement by months or years.
Where enforcement proceedings are already imminent, the first priority is documentation. The creditor must assemble a complete enforcement file: the original or certified copy of the award, the arbitration agreement, certified Polish translations of both, and any procedural records that demonstrate due process was observed. If the award was rendered by an arbitral tribunal seated in a jurisdiction that issues apostilles under the Hague Convention, obtaining an apostilled copy eliminates one potential challenge point.
The second priority is asset identification. Polish enforcement proceedings are self-executing in the sense that the komornik requires specific information about the debtor's assets to proceed with seizure. An enforcement order against unknown assets is largely nominal. Pre-enforcement due diligence – examining Polish land registry records, commercial register filings for Polish companies, and public financial disclosures – provides the asset map needed to make enforcement practically effective.
The third priority is the interim security application. A well-supported zabezpieczenie application, filed simultaneously with or immediately before the enforcement petition, prevents asset dissipation during the proceedings. The creditor should be prepared to provide security for any loss caused to the respondent if the enforcement application ultimately fails. The level of security required is set by the court and is typically proportionate to the contested amount.
Where a respondent mounts a public policy defence, the creditor's response should focus squarely on the Sąd Najwyższy's established doctrine: the public policy exception is reserved for fundamental breaches, not for disagreement with the outcome. A detailed factual account of the arbitral process. demonstrating that each party had a full and equal opportunity to present its case. That the arbitral tribunal acted within its mandate. Additionally, that the award addresses all claims within the scope of the submission. is the most effective counter to a public policy challenge.
Where enforcement is sought simultaneously in multiple jurisdictions, coordination matters. An enforcement creditor that obtains a zabezpieczenie in Poland while simultaneously enforcing in Germany, Austria, or another EU jurisdiction benefits from the mutual recognition of provisional measures under EU procedural legislation. Sequencing enforcement actions to maximise asset coverage while avoiding inconsistent rulings requires strategic legal coordination across jurisdictions.

Outlook: regulatory trajectory and what to monitor
The Polish enforcement environment is not static. Several developments deserve attention from international practitioners and business clients over the coming years.
First, the digitalisation of Polish civil proceedings is advancing. Polish civil procedure rules have been amended to permit electronic filing, electronic service of process, and remote hearings in commercial matters. These changes reduce procedural friction for international creditors who would otherwise need a physical presence in Poland at multiple stages of enforcement proceedings. The practical implementation varies by court and by region, but the direction of travel is clear.
Second, the relationship between EU law and Polish constitutional law continues to generate uncertainty. The Trybunał Konstytucyjny (Constitutional Tribunal of Poland) has issued rulings questioning the primacy of EU law in specific contexts. The European Court of Justice and the Court of Justice of the EU have responded with strong reassertions of EU law supremacy. For enforcement practitioners, the practical consequence is that EU-law-based arguments. particularly those relying on the Brussels I regulation or EU fundamental rights provisions. may encounter greater scrutiny in Polish courts than they would have a decade ago. This does not mean those arguments are unavailable; it means they must be developed with greater care.
Third, the trajectory of investor-state arbitration involving Polish state entities is worth monitoring. Poland has faced a series of energy-sector ECT claims. The Polish government has taken active steps to limit its exposure to future ECT claims, including supporting the EU-level effort to establish a multilateral investment court as an alternative to ad hoc investor-state arbitration. If those efforts produce a new institutional structure, the enforcement of investment awards against Polish assets may shift from the New York Convention framework to a treaty-specific mechanism with different procedural rules.
Fourth, the interaction between Polish insolvency legislation and arbitration is an area of active development. Amendments to insolvency and restructuring rules in recent years have introduced new restructuring procedures that affect the treatment of arbitration agreements and pending arbitral proceedings. Creditors with claims against Polish companies undergoing restructuring must monitor the procedural status of those proceedings closely to avoid having their arbitral awards subordinated to restructuring plan terms.
Fifth, the post-Brexit enforcement of English court judgments in Poland remains a live issue. The UK and Poland have not concluded a bilateral enforcement treaty to replace the Brussels I regulation. English court judgments must now be recognised under Polish civil procedure rules applicable to non-EU judgments. This is a materially more demanding process. Parties with English governing law clauses and English jurisdiction clauses in contracts with Polish counterparties should consider whether arbitration. with its New York Convention enforcement route. now offers a more reliable path to recovery than English court litigation.
The cumulative effect of these developments is that cross-border enforcement in Poland rewards specialised, forward-looking legal planning. The legal instruments are available. The treaty regime is solid. The courts, taken as a whole, are genuinely committed to the pro-enforcement principle. But the procedural gaps, the constitutional complexities, and the evolving insolvency interface mean that the journey from award or judgment to actual recovery requires expert navigation at every stage.
Frequently asked questions
Q: How long does it take to enforce a foreign arbitral award in Poland?
A: Enforcement of a foreign arbitral award in Poland typically takes between six months and two years, depending on the complexity of the matter and whether the respondent mounts a substantive challenge. First-instance proceedings at the regional court level are generally faster. Appeals to the court of appeal and, in limited cases, to the Supreme Court of Poland can extend the timeline considerably. Instructing experienced local counsel early in the process helps to anticipate and manage procedural delays.
Q: Can a Polish court refuse to enforce an award made under ICC Rules or UNCITRAL rules on public policy grounds?
A: Yes, but Polish courts apply the public policy exception narrowly. Mere procedural differences or outcomes unfavourable to a Polish party do not satisfy the threshold. Courts look for a serious breach of fundamental legal principles, such as a violation of constitutional rights or a clear conflict with overriding mandatory rules. The Sąd Najwyższy has consistently held that the public policy defence must not become a tool to re-examine the merits of a properly conducted arbitration.
Q: Is Poland a good seat of arbitration for European cross-border disputes?
A: Poland is an increasingly credible seat of arbitration for European disputes. Polish civil procedure rules governing arbitration are closely modelled on UNCITRAL legislative standards. The country is a signatory to the New York Convention, and Polish courts have demonstrated a generally pro-enforcement stance. Warsaw hosts established arbitral institutions with modern procedural rules. For disputes involving Central and Eastern European counterparties, choosing Poland as the seat of arbitration can offer a practical balance of neutrality, accessibility, and enforcement reliability. Engaging a lawyer in Poland with cross-border experience is advisable when structuring arbitration clauses for CEE-facing transactions.
