Litigation & Arbitration in Poland

Poland offers international businesses a structured, EU-compliant dispute resolution framework built on the Code of Civil Procedure (Kodeks postępowania cywilnego, KPC) and a growing arbitration culture anchored in Warsaw. When a commercial relationship breaks down, the choice between state courts, institutional arbitration and alternative dispute resolution (ADR) determines not only the timeline but the total cost and enforceability of any outcome. This article maps the full landscape - from filing a claim in a Polish district court to enforcing a foreign arbitral award - and identifies the practical traps that catch international clients most often.

Poland operates a four-tier judicial structure for civil and commercial matters. District courts (sądy rejonowe) handle claims up to PLN 75,000. Regional courts (sądy okręgowe) have first-instance jurisdiction over larger commercial claims and most corporate disputes. Appeals go to appellate courts (sądy apelacyjne), and the Supreme Court (Sąd Najwyższy) reviews points of law. Since the 2019-2023 judicial reforms, commercial divisions of regional courts have gained dedicated dockets for business disputes, reducing average first-instance duration in Warsaw to roughly 18-24 months for straightforward contract claims, though complex multi-party litigation can run considerably longer.

A critical structural feature is the Commercial Court (Sąd Gospodarczy), a specialised division within regional courts. Under Article 458(1) KPC, commercial cases - defined broadly to include disputes between entrepreneurs arising from business activity - must be filed in this division. International clients sometimes file in the wrong division, causing procedural delays of several weeks while the case is transferred.

Venue rules follow Articles 27-46 KPC. The general rule places jurisdiction at the defendant's registered seat. Contract disputes may alternatively be brought where performance was due. Parties may also agree on exclusive jurisdiction by written clause, which Polish courts respect provided the clause is unambiguous and covers the specific type of dispute.

Electronic filing is available through the e-Sąd system for payment order proceedings (elektroniczne postępowanie upominawcze, EPU). For standard commercial litigation, submissions are filed in paper or, increasingly, through the Portal Informacyjny system for document exchange with courts. The Ministry of Justice has been expanding digital infrastructure, but full e-filing for contested commercial cases remains partial as of the current reform cycle.

Polish civil procedure does not impose a mandatory pre-litigation mediation step for commercial disputes, but Article 187(1)(3) KPC requires the claimant to state in the statement of claim whether the parties attempted mediation or another ADR method, and if not, why not. Courts may adjourn proceedings and refer parties to mediation under Article 183(8) KPC. Failure to engage with ADR does not bar the claim, but judges in Warsaw and Kraków commercial divisions increasingly use this power, particularly in disputes with an ongoing business relationship.

Interim relief (zabezpieczenie roszczenia) is governed by Articles 730-757 KPC. A claimant may apply for interim measures before or during proceedings. The court must be satisfied that the claim is credible (uprawdopodobnienie) and that without the measure, enforcement would be impossible or seriously impeded. Polish courts grant interim measures relatively quickly - typically within 7-14 days for urgent applications, and in ex parte cases (without notifying the defendant) within 3-5 working days. Common measures include freezing bank accounts, prohibiting disposal of assets, and appointing a custodian over disputed shares.

A non-obvious risk: interim measures in Poland lapse automatically if the claimant does not file the main claim within two weeks of the measure being granted (Article 733 KPC). International clients who obtain a freeze order and then pause to negotiate sometimes lose the measure entirely because they miss this deadline.

Security for costs is not a standard feature of Polish procedure, but courts may require a claimant domiciled outside the EU to provide a cautio iudicatum solvi (security for the defendant's potential costs) under Article 1119 KPC, unless an international treaty exempts them. EU-domiciled claimants are exempt under EU procedural law.

Once a statement of claim (pozew) is filed, the court issues a writ and serves it on the defendant, who has 14 days to file a response in payment order proceedings or a period set by the court (typically 4-6 weeks) in standard proceedings. Under the 2019 amendments to KPC, commercial cases follow a stricter preclusion regime: both parties must present all their evidence and arguments in the initial pleadings, with late submissions admissible only if the party demonstrates it could not have presented them earlier. This rule catches international clients who are accustomed to more flexible common-law disclosure processes.

The evidentiary phase in Polish courts relies primarily on documentary evidence and witness testimony. Expert witnesses (biegli sądowi) appointed by the court play a central role in technical, financial and valuation disputes. Court-appointed experts are drawn from official lists maintained by regional courts. Their opinions carry significant weight, and challenging them requires a formal motion supported by substantive objections. The process of obtaining an expert opinion adds 3-6 months to proceedings in complex cases.

Court fees (opłata sądowa) are calculated as a percentage of the claim value under the Act on Court Costs in Civil Cases (Ustawa o kosztach sądowych w sprawach cywilnych). The fee is capped at PLN 200,000 for most commercial claims. Lawyers' fees are subject to separate agreement; for mid-size commercial disputes, professional fees typically start from the low tens of thousands of PLN and scale with complexity. The losing party bears the winner's costs, but courts apply a tariff (rozporządzenie Ministra Sprawiedliwości) that often falls below actual market rates, meaning full cost recovery is rarely achieved.

Three practical scenarios illustrate the range of situations:

• A foreign supplier with a PLN 500,000 unpaid invoice against a Polish distributor files in the regional commercial court in Warsaw. With clear documentary evidence, a payment order (nakaz zapłaty) may be obtained within 4-6 weeks. If the defendant objects, the case moves to full proceedings, adding 12-18 months.
• A minority shareholder in a Polish limited liability company (spółka z ograniczoną odpowiedzialnością, sp. z o.o.) challenges a resolution of the shareholders' meeting. Under Article 252 of the Commercial Companies Code (Kodeks spółek handlowych, KSH), the action must be filed within one month of the resolution. Missing this deadline extinguishes the right entirely.
• A construction contractor disputes a penalty clause deduction by a state-owned developer. The dispute involves technical expert evidence and may run 3-4 years through two instances, with total legal costs reaching the mid-hundreds of thousands of PLN.

A common mistake among international clients is underestimating the preclusion rules. Presenting new evidence after the initial exchange of pleadings is extremely difficult, so thorough preparation before filing is essential.

Arbitration in Poland is governed by Part V of KPC (Articles 1154-1217), which is modelled on the UNCITRAL Model Law. Poland is a signatory to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, making Polish awards enforceable in over 170 jurisdictions and foreign awards enforceable in Poland.

The principal institutional arbitration body is the Court of Arbitration at the Polish Chamber of Commerce (Sąd Arbitrażowy przy Krajowej Izbie Gospodarczej, SA KIG) in Warsaw. It administers both domestic and international cases under its own rules, which were updated to align with international best practice. The Lewiatan Court of Arbitration (Sąd Arbitrażowy przy Konfederacji Lewiatan) is another established institution, particularly active in employment-related commercial disputes and mid-market transactions. For purely international disputes, parties frequently choose the ICC, VIAC or SCC, with Warsaw as the seat.

Choosing the seat of arbitration in Poland has procedural consequences. Polish courts at the seat have supervisory jurisdiction: they hear challenges to arbitral awards (Article 1205 KPC), applications to set aside awards (Article 1206 KPC), and requests for interim measures in support of arbitration (Article 1166 KPC). The grounds for setting aside a Polish award are narrow and align with international standards - lack of valid arbitration agreement, violation of due process, award outside the scope of submission, or conflict with public policy (klauzula porządku publicznego).

Ad hoc arbitration under UNCITRAL Rules is also used, particularly in joint venture and M&A disputes where the parties prefer not to involve an institution. The risk with ad hoc proceedings in Poland is the absence of administrative support: the parties must manage all logistics, and if the tribunal becomes deadlocked on procedural matters, recourse to the supervising court adds delay.

Arbitration costs in Poland are generally lower than in Western European seats for mid-market disputes. SA KIG registration fees and arbitrator fees are calculated on a sliding scale; for a dispute of EUR 1-5 million, total institutional costs typically fall in the range of tens of thousands of EUR, with legal fees additional. This compares favourably with ICC or LCIA proceedings of similar size.

A non-obvious risk in drafting Polish arbitration clauses: under Article 1161(2) KPC, an arbitration clause in a contract with a consumer is void. For B2B contracts, the clause must be in writing (broadly interpreted to include electronic form). Clauses that are ambiguous about the scope of disputes covered - for example, clauses that say 'disputes arising from this contract' but are silent on tort claims - may be interpreted narrowly by Polish courts when a party challenges jurisdiction.

Poland has invested significantly in ADR infrastructure since the EU Mediation Directive (2008/52/EC) was transposed into national law. Mediation in commercial disputes is regulated by Articles 183(1)-183(15) KPC. Mediation may be court-referred or contractual. A mediation settlement (ugoda mediacyjna) approved by a court has the force of a court judgment and is directly enforceable.

The practical uptake of mediation in Polish commercial disputes remains lower than in some Western European jurisdictions, but it is growing. Warsaw's commercial court actively refers cases to mediation at the first hearing, and parties who refuse without good reason may face adverse cost consequences. For disputes involving ongoing business relationships - distribution agreements, long-term supply contracts, joint ventures - mediation offers a faster and cheaper path than litigation, typically resolving within 1-3 months at a fraction of litigation costs.

Conciliation (postępowanie pojednawcze) under Articles 184-186 KPC allows a party to invite the opponent to a conciliation hearing before a court, without filing a full claim. This procedure is rarely used in commercial practice but can be tactically useful to interrupt the limitation period (przerwanie biegu przedawnienia) under Article 123(1)(1) of the Civil Code (Kodeks cywilny, KC).

Expert determination (ekspertyza umowna) is not separately regulated in Polish law but is recognised as a contractual mechanism. Parties to complex technical or valuation disputes sometimes agree in their contracts that a named expert or an expert appointed by a professional body will determine a disputed value, with the determination binding as a matter of contract. Polish courts enforce such clauses, treating the expert's determination as a contractual fact rather than a judicial finding.

Many underappreciate the limitation period rules when choosing between ADR and litigation. Under Article 118 KC, the general limitation period for commercial claims is three years. For claims arising from a business activity, the period runs from the date the claim became due. Filing a court claim, initiating arbitration, or commencing court-referred mediation each interrupt the period. A contractual mediation clause that requires the parties to attempt mediation before arbitration or litigation does not by itself interrupt limitation - only the formal procedural steps do.

Obtaining a judgment or award is only half the task. Enforcement in Poland is conducted by court bailiffs (komornicy sądowi) under the Code of Civil Enforcement Procedure (Kodeks postępowania egzekucyjnego). A domestic court judgment becomes enforceable once the court issues an enforcement clause (klauzula wykonalności). For arbitral awards, the court must first recognise the award and issue the enforcement clause under Article 1214 KPC, a process that typically takes 1-3 months in uncontested cases.

Foreign court judgments from EU member states are enforced under EU Regulation 1215/2012 (Brussels I Recast), which abolished the exequatur requirement for most civil and commercial judgments. A creditor with an EU judgment can proceed directly to enforcement in Poland by presenting the judgment and the standard certificate. For judgments from non-EU states, enforcement requires a separate recognition proceeding under Articles 1145-1153 KPC, which examines reciprocity, jurisdiction of the foreign court, and compliance with Polish public policy.

Foreign arbitral awards are enforced under the New York Convention. Polish courts apply the Convention's grounds for refusal narrowly. The most frequently invoked ground in practice is violation of Polish public policy, but courts interpret this restrictively - it covers fundamental procedural fairness and core legal principles, not mere disagreement with the outcome.

Asset tracing before enforcement is a practical necessity in contested cases. Polish law allows a judgment creditor to request information about the debtor's assets from the bailiff, who can query the tax authority, social insurance registry (ZUS), land registry (księgi wieczyste) and vehicle registry. This process takes 2-4 weeks and provides a reasonable picture of attachable assets. A common mistake is waiting until after judgment to investigate assets; by then, a sophisticated debtor may have restructured its holdings.

The cost of enforcement depends on the amount recovered. Bailiff fees are regulated by statute and are generally modest relative to the amount in dispute, but legal fees for managing enforcement proceedings add to the total. For cross-border enforcement involving multiple jurisdictions, costs can be substantial, and the decision to pursue enforcement should be weighed against the realistic prospect of recovery.

What is the biggest practical risk when litigating in Poland as a foreign company?

The most significant risk is the strict preclusion regime introduced by the 2019 KPC amendments. Polish commercial courts require parties to present all evidence and legal arguments in their initial pleadings. Evidence submitted late is generally inadmissible unless the party proves it was impossible to present earlier. Foreign companies accustomed to common-law disclosure or more flexible civil procedure systems often arrive at the first hearing without a complete evidentiary package, which can be fatal to the claim. Thorough pre-litigation preparation - gathering all documents, identifying witnesses and commissioning any necessary expert reports before filing - is not optional; it is structurally required by Polish procedure.

How long and how costly is arbitration in Poland compared to court litigation?

Institutional arbitration at SA KIG or Lewiatan typically concludes within 12-18 months for a straightforward two-party commercial dispute, compared to 18-36 months for two-instance court litigation on a similar matter. For disputes in the EUR 500,000 - EUR 5 million range, total costs (institutional fees plus legal fees) in Polish arbitration are generally lower than equivalent ICC or LCIA proceedings, though higher than first-instance court litigation alone. The economic case for arbitration strengthens when confidentiality, enforceability across multiple jurisdictions under the New York Convention, or the need for a specialist arbitrator outweigh the cost differential. For smaller disputes below PLN 200,000, court litigation or mediation is usually more cost-effective.

When should a party choose mediation over arbitration or litigation in Poland?

Mediation is the rational choice when three conditions align: the parties have an ongoing commercial relationship worth preserving, the dispute has a negotiable middle ground rather than a binary win-lose structure, and both sides are willing to engage in good faith. In practice, this covers distribution and supply disputes, joint venture disagreements over operational matters, and construction disputes where the parties must continue working together. Mediation in Poland typically resolves within 1-3 months and costs a fraction of arbitration or litigation. Where one party is clearly in default and the other needs a binding, enforceable outcome quickly - for example, an unpaid invoice with no genuine defence - a payment order proceeding or expedited arbitration is more appropriate than mediation.

Poland's dispute resolution framework is sophisticated, EU-aligned and increasingly accessible to international businesses. The key strategic decisions - court versus arbitration, litigation versus mediation, domestic versus international seat - each carry distinct cost, time and enforceability implications that must be assessed against the specific dispute. Preclusion rules, limitation periods and interim measure deadlines create hard procedural traps that reward early legal engagement and punish delay.
