How to Enforce a Foreign Court Judgment in Poland (2026): Procedure, Documents, Defences and Timelines

Enforce foreign judgment Poland searches are rising as creditors, in-house counsel and overseas law firms confront the practical realities of cross-border recovery in 2026. The route you take depends almost entirely on where the judgment originated: judgments from EU Member States benefit from the streamlined regime under the Brussels I Recast Regulation, while UK judgments post-Brexit and US or other third-country judgments must travel through Poland’s domestic recognition procedure. This guide sets out, step by step, how to enforce a foreign judgment in Poland, the correct procedural route, the documents and translations required, realistic timelines and costs, the most common grounds for refusal, and the mechanics of bailiff enforcement once recognition is secured.

It is written for practitioners and decision-makers who need to assess not just whether enforcement is legally possible, but whether it is commercially worthwhile.

Executive summary: Can you enforce a foreign judgment in Poland?

In most cases, yes. A judgment given in another EU Member State is recognised in Poland without any special procedure under Regulation (EU) No 1215/2012 (Brussels I Recast), and is enforceable once the creditor produces the required certificate, no separate declaration of enforceability (exequatur) is needed. Judgments from outside the EU, including UK judgments after Brexit and US judgments, require a domestic recognition or enforceability procedure before the Polish courts under the Polish Civil Procedure Code (Kodeks postępowania cywilnego).

High-level expectations: EU recognition and enforcement is typically a matter of weeks to a few months; third-country recognition usually takes several months and can exceed a year where the debtor raises defences. The principal grounds for refusal are public policy (ordre public), defective service, and irreconcilable judgments. The practical next steps are to instruct Polish counsel, secure provisional or preservation measures where there is a risk of asset dissipation, and prepare authenticated and sworn-translated documents early. This article is general guidance and not legal advice; enforcement outcomes turn on the specific facts and the origin of the judgment.

Routes to recognition and enforcement in Poland (EU vs non-EU)

Before you spend money on translations and court fees, identify the correct route. Poland operates two fundamentally different systems for recognising foreign judgments, and choosing the wrong one wastes time and cost. The first is the EU regime governed by the Brussels I Recast Regulation; the second is the domestic procedure under the Polish Civil Procedure Code, which applies to judgments from countries outside the Brussels regime. To enforce a foreign judgment in Poland effectively, you must first classify the judgment by its country of origin and the legal instruments that bind that country and Poland.

EU judgments (Brussels I Recast): the practical process

For civil and commercial judgments given by courts of EU Member States, Regulation (EU) No 1215/2012 (Brussels I Recast) provides the governing framework for proceedings instituted on or after 10 January 2015. The core principle is automatic recognition: a judgment given in one Member State is recognised in the other Member States without any special procedure. Enforcement is equally streamlined, the old exequatur requirement has been abolished for judgments falling within the Regulation’s scope.

In practice, the creditor who wishes to enforce an EU judgment in Poland needs two things: a copy of the judgment satisfying the conditions necessary to establish its authenticity, and a certificate issued by the court of origin under Article 53 of the Regulation using the standard form in Annex I. That certificate confirms the judgment is enforceable in the Member State of origin and summarises its key terms. Armed with these documents, the creditor may proceed directly to enforcement in Poland, subject to the debtor’s limited right to apply for refusal of enforcement on the grounds set out in the Regulation. A sworn Polish translation of the certificate, and potentially the judgment, may be required by the enforcement authority.

UK judgments (post-Brexit): practical options

Since the United Kingdom left the EU, UK judgments no longer benefit from the Brussels I Recast regime for proceedings commenced after the end of the transition period. There is no automatic recognition and no Article 53 certificate route for UK judgments in Poland. This is the single most consequential change for creditors holding English judgments, and it is why UK judgment enforcement in Poland post-Brexit requires careful analysis of the available pathways.

For UK judgments, the creditor must generally rely on Poland’s domestic recognition procedure under the Polish Civil Procedure Code, in the same way as for other third-country judgments. Where an applicable international instrument exists, for example the Hague Convention of 30 June 2005 on Choice of Court Agreements, to which both the UK and the EU (and therefore Poland) are parties, where the dispute arises under an exclusive choice-of-court agreement within its scope, that instrument may provide a more structured route. The Hague Convention of 2 July 2019 on the Recognition and Enforcement of Foreign Judgments may also become relevant as its ratification develops.

Because the position is more complex than it was before Brexit, early advice from Polish counsel is essential to confirm which route applies to a given UK judgment and what the debtor is likely to argue.

US and other third-country judgments: the domestic recognition route

Poland has no general bilateral enforcement treaty with the United States, and US judgments therefore fall within the domestic recognition procedure. US judgment recognition in Poland proceeds through the Polish courts, which examine whether statutory conditions are met and whether any ground for refusal applies. Poland will, as a matter of general practice, recognise and enforce a third-country judgment once the court is satisfied the judgment is final, that service and due process were respected, and that recognition would not offend Polish public policy.

The same domestic framework applies to judgments from most non-EU, non-treaty jurisdictions. Authentication of the judgment, a sworn translation, and clear proof of proper service on the defendant are the practical cornerstones of a successful application. Answering the common question, does Poland recognise UK or US court judgments?, the short answer is yes, but only through this domestic court procedure rather than any automatic mechanism.

Step-by-step procedure to enforce a foreign judgment in Poland

The procedural mechanics differ between the EU route and the domestic route, but the underlying sequence, classify, assemble, file, obtain a decision, enforce, is consistent. The following is a practitioner-level walkthrough of what to file in the Polish courts and in what order, as governed by the Polish Civil Procedure Code and, for EU judgments, by Regulation (EU) No 1215/2012.

Filing and court fees

Under the domestic procedure, applications for recognition or for a declaration of enforceability are generally made to the competent regional court (sąd okręgowy) with territorial jurisdiction, typically determined by the debtor’s domicile or seat, or otherwise by the place where enforcement is to be carried out. For EU judgments relying on the Article 53 certificate, the creditor may move more directly toward enforcement without a prior exequatur application; the debtor’s challenge, if any, is dealt with by the competent court.

Court fees are payable on filing in accordance with the Act on Court Costs in Civil Matters. The creditor should budget for the court fee, the cost of sworn translations, and authentication or apostille costs. The application must identify the parties, the foreign judgment, the sum or obligation to be enforced, and the legal basis for recognition. It is prudent to set out, proactively, why none of the statutory grounds for refusal apply, anticipating the debtor’s defences at the outset reduces the risk of adjournment.

Service and evidence requirements

Proof that the originating proceedings were properly served on the defendant is central to any application to enforce a foreign judgment in Poland. Where the defendant did not appear in the original proceedings, the creditor must demonstrate that the document instituting the proceedings was served in sufficient time and in a manner enabling the defendant to arrange a defence. Instruments on the service of documents abroad, such as the Hague Service Convention of 15 November 1965, are frequently relevant here, because they establish the recognised channels for cross-border service and provide the evidentiary records that satisfy a Polish court.

Evidence of the judgment’s finality is equally important. For third-country judgments, the court will expect confirmation that the judgment is final and enforceable in the country of origin, usually in the form of a finality or enforceability certificate from the originating court. Gaps in service evidence or finality are among the most common reasons applications stall.

Hearing and possible interlocutory steps

The court examines the application and, for domestic recognition, may hold a hearing at which the debtor can raise objections. For EU judgments, the process is more administrative, with the debtor’s challenge arising only if it applies for refusal of recognition or enforcement. Where there is a real risk that the debtor will move or conceal assets, the creditor should consider applying for provisional or preservation measures (zabezpieczenie) in parallel, so that assets are secured before the debtor has an opportunity to react. Securing interim relief early can be the difference between a paper victory and actual recovery.

Required documents and checklist for recognition in Poland

Document preparation is where most applications succeed or fail. Polish courts are exacting about authentication and translation, and incomplete bundles are routinely sent back. The following checklist answers the recurring question, what documents are required to recognise a foreign judgment in Poland?, and should be assembled before the application is filed.

• Certified copy of the judgment. A copy of the foreign judgment satisfying the conditions necessary to establish its authenticity, issued by the originating court.
• Finality or enforceability certificate. For third-country judgments, documentary confirmation that the judgment is final and enforceable in the country of origin. For EU judgments, the Article 53 certificate issued on the Annex I form under Regulation (EU) No 1215/2012.
• Apostille or legalisation. Where the originating country is party to the Hague Apostille Convention of 1961, an apostille suffices; otherwise, consular legalisation may be required to authenticate the judgment and accompanying documents.
• Sworn translation. A Polish translation prepared by a sworn translator (tłumacz przysięgły) of the judgment, certificates and supporting documents. Informal or uncertified translations are generally not accepted.
• Proof of service. Evidence that the defendant was duly served with the originating process, especially where the defendant did not appear, frequently documented through Hague service channels.
• Power of attorney. A power of attorney authorising Polish counsel to act, properly executed and, where necessary, translated and authenticated.
• Enforcement title details. Precise identification of the sum, interest, costs and obligations to be enforced, so the enforcement clause and subsequent bailiff instructions can be drawn without ambiguity.

A practical tip: prepare a bilingual cover letter that cross-references each document to the relevant statutory requirement. This helps the court confirm completeness quickly and reduces procedural friction. Creditors preparing to enforce a foreign judgment in Poland should treat document assembly as the critical path item in the project timeline, because sworn translation and authentication of overseas documents can take weeks.

Timelines, costs and practical expectations

Realistic planning depends on understanding how long recognition and enforcement takes in Poland and what it costs. The headline distinction is between the EU route, which is faster and more predictable, and the domestic route for third-country judgments, which is slower and more exposed to the debtor’s defences.

Typical timeline: EU vs UK vs US

Costs fall into predictable categories: court fees payable on filing, sworn translation fees that scale with the length and complexity of the documents, apostille or legalisation costs, legal fees for Polish counsel, and bailiff (komornik) fees levied on enforcement. For contested third-country cases, counsel time is the largest variable, because responding to the debtor’s defences can require additional pleadings and evidence. The Ministry of Justice maintains guidance on court procedures, and continued digitisation of court filing is gradually improving predictability for straightforward applications. Creditors deciding whether to enforce a foreign judgment in Poland should weigh these costs against the recoverable sum and the debtor’s known assets before committing.

Grounds for refusal and common defences: how to mitigate

Understanding the grounds on which a Polish court may refuse recognition or enforcement is essential, both to assess risk and to pre-empt the debtor’s defences. The grounds differ in detail between the Brussels I Recast regime and the domestic procedure, but the themes overlap. The question practitioners are most often asked, what are the main defences?, resolves into a familiar list.

• Public policy (ordre public). Recognition may be refused if it would be manifestly contrary to Polish public policy. This is a narrow exception, not a route to re-litigate the merits. The case law of the Supreme Court of Poland (Sąd Najwyższy) confines it to fundamental principles of the Polish legal order. Mitigation: anticipate the argument and demonstrate that the foreign proceeding respected fair-trial standards and that the outcome does not offend any fundamental principle.
• Defective service. Where the defendant did not appear and was not served with the originating document in sufficient time to arrange a defence, recognition may be refused. Mitigation: assemble complete Hague service records and prove timely, proper service from the outset.
• Irreconcilable judgments. A foreign judgment that is irreconcilable with a judgment between the same parties in Poland, or with an earlier judgment from another state entitled to recognition, may be refused. Mitigation: conduct conflict checks and address any prior Polish proceedings in the application.
• Lack of jurisdiction. In limited circumstances, the jurisdiction of the originating court may be examined, particularly where protective jurisdictional rules (for example in insurance, consumer or employment matters) or exclusive jurisdiction were engaged. Mitigation: prepare jurisdictional pleadings demonstrating the originating court’s proper basis.
• Fraud. Allegations that the judgment was obtained by fraud can be raised. Mitigation: be ready to rebut with evidence of the procedural integrity of the original proceedings.
• Finality and limitation. A judgment that is not yet final, or where the right to enforce has become time-barred, will not support enforcement. Mitigation: file promptly, confirm finality, and monitor the applicable limitation period for enforcement in Poland.

CJEU case law interpreting the Brussels I Recast Regulation is an authoritative reference point for the EU grounds for refusal, particularly on public policy and the service exception, and should be consulted when framing or resisting a defence. For domestic recognition, Supreme Court practice guides how the Polish courts apply the equivalent statutory grounds under the Civil Procedure Code. Across both regimes, the consistent lesson is that the debtor’s defences are most effective where the creditor’s documentation is weakest, which is why disciplined document preparation is itself the best defence strategy when you set out to enforce a foreign judgment in Poland.

Post-recognition enforcement: Polish bailiffs (komornik) and asset recovery

Recognition or a declaration of enforceability is not the end of the process, it is the licence to begin actual recovery. In Poland, enforcement is carried out by a court bailiff (komornik sądowy), a public official who executes enforcement titles against the debtor’s assets. Court bailiff enforcement in Poland is where a recognised judgment becomes money in the creditor’s account, so the handover from the court stage to the komornik stage must be managed carefully.

Instructing the komornik

Once the foreign judgment is enforceable in Poland and an enforcement clause (klauzula wykonalności) has been obtained where required, the creditor instructs a komornik to open enforcement proceedings. The instruction identifies the enforcement title, the sums claimed, and the enforcement measures sought. The komornik can conduct searches to identify the debtor’s assets, bank accounts, employment income, movable property and real estate, and a well-prepared instruction with any available intelligence on the debtor’s assets accelerates recovery. Provide the komornik with a clear, itemised schedule of the debt, including principal, interest and recoverable costs.

Enforcement against bank accounts and movables

Among the most effective measures are attachments against the debtor’s bank accounts, which can freeze and then transfer funds to satisfy the debt, and seizure of movable property (such as vehicles, equipment and stock) for sale. Where there is a risk of dissipation, securing preservation or freezing measures before or alongside recognition protects the creditor’s position, so that the komornik has assets to act against once enforcement opens.

Land registry (księgi wieczyste) enforcement

For larger debts, enforcement against real estate is often decisive. The komornik can effect the attachment of the debtor’s property, with the relevant entry made in the land and mortgage register (księgi wieczyste) and, ultimately, pursue a judicial sale of the property. Enforcement against immovables is slower than bank-account attachment but can unlock substantial value where the debtor holds real estate. Where the debtor’s assets are located in other EU Member States, cross-border enforcement cooperation under the EU framework allows the creditor to pursue those assets abroad, coordinated from the Polish base of the recognised judgment.

Practical tips: common practitioner pitfalls and templates

Experienced practitioners see the same avoidable mistakes derail enforcement. Keep this list to hand when you prepare to enforce a foreign judgment in Poland:

• Improper authentication. Failing to apostille or legalise the judgment and supporting documents correctly is a frequent cause of rejection. Confirm whether an apostille or consular legalisation is required for the country of origin before filing.
• No sworn translation. Translations must be by a sworn translator (tłumacz przysięgły); informal or in-house translations will not be accepted.
• Weak evidence of service. Incomplete service records are the classic opening for a public policy or defective-service defence. Assemble full Hague service documentation early.
• Late commencement. Acting too late can mean the enforcement right is time-barred. File promptly and track the limitation period.
• Ignoring local formalities. Missing jurisdictional details, an improperly executed power of attorney, or an imprecise statement of the sum claimed all cause delay. A bilingual cover letter cross-referencing documents to requirements helps the court process the bundle smoothly.

When instructing the komornik, hand over a clean, itemised enforcement schedule and any intelligence on the debtor’s assets. The more precise the instruction, the faster the bailiff can act.

Next steps and how specialist lawyers can help

The decision to enforce a foreign judgment in Poland should be grounded in a clear-eyed assessment of the route available, the strength of your documentation, the debtor’s likely defences, and, above all, whether the debtor holds reachable assets. The practical sequence is to instruct experienced Polish counsel for a case assessment, confirm the correct recognition route, assemble authenticated and sworn-translated documents, secure provisional measures where dissipation is a risk, and line up a komornik to move the moment the judgment becomes enforceable.
