On paper, an arbitration clause looks like a single sentence buried in the boilerplate. In practice, a poorly drafted clause can strip a company of its chosen forum, invalidate the entire dispute-resolution mechanism, or hand the opposing party a procedural weapon before the substantive argument even begins. For contracts governed by Polish law – or performed in Poland – the drafting choices matter more than most clients expect.
Polish arbitration law is codified in Part Five of the Kodeks postępowania cywilnego (Code of Civil Procedure, KPC). A valid arbitration clause must be in writing, identify the subject matter of disputes covered, and – where institutional arbitration is chosen – name a specific arbitral institution. Failure on any of these three points risks the clause being declared ineffective by a Polish court, leaving the parties in ordinary litigation before the district or regional court.
This guide walks through the step-by-step process of drafting an arbitration clause for a Polish contract: what elements are legally required, which institutions are available, what the procedure and cost look like, and where companies most often go wrong. Three business scenarios – a manufacturing supplier, a cross-border IT services agreement, and a foreign investor entering through a joint venture – illustrate how the choices play out in practice.
What makes an arbitration clause valid under Polish law?
The KPC sets a writing requirement as the baseline. A clause embedded in a contract, exchanged in correspondence, or incorporated by reference to standard terms all satisfy this threshold – provided the reference is explicit. Polish courts, including the Sąd Najwyższy (Supreme Court of Poland), have confirmed that a general reference to "the seller's standard conditions" is insufficient unless those conditions were actually communicated to the other party before signing.
Three elements must appear in any clause. First, the parties' agreement to exclude state-court jurisdiction. Second, a description – even broad – of the disputes covered. Third, either a named arbitral institution or a mechanism for constituting an ad hoc tribunal. Missing any element gives the respondent a ready-made challenge. Polish courts will not cure a defective clause by implication.
The writing requirement is satisfied digitally. An email exchange confirming arbitration, a DocuSign-executed contract, or an electronic data room closing set all count. This matters for IT and fintech agreements, where contracts are rarely executed on paper. The National Court Register (KRS) filing of a company does not affect clause validity, but it confirms the signatory's authority – a point worth checking before relying on the clause.
One concrete figure: a challenge to arbitral jurisdiction must be raised no later than the submission of the first statement of defence in the arbitral proceedings. Miss that deadline and the objection is waived permanently – an irreversible consequence that forfeits the right to contest the tribunal's authority before Polish courts at the enforcement stage.
Which arbitral institution should you choose?
Institutional choice is the single most consequential drafting decision. Poland has several established venues. The Sąd Arbitrażowy przy Krajowej Izbie Gospodarczej (Court of Arbitration at the Polish Chamber of Commerce, SA KIG) in Warsaw is the largest domestic institution, with rules last revised in 2019. The Lewiatan Court of Arbitration (Lewiatan) is a second well-regarded Polish option, particularly for mid-market disputes. For cross-border contracts, the ICC International Court of Arbitration and the Vienna International Arbitral Centre (VIAC) are common choices among foreign investors operating in Poland.
Each institution carries a different cost structure. SA KIG fees are calculated as a percentage of the amount in dispute, with a minimum registration fee of around PLN 3,000 and an arbitrator fee schedule that scales to approximately 1–3% of the claim value for disputes above PLN 1m. ICC fees are denominated in EUR and follow a separate table – typically higher for smaller disputes but proportionally competitive above EUR 2m. Choosing the wrong institution can mean paying two to three times more in administration fees for the same dispute value.
Ad hoc arbitration – where the parties appoint arbitrators directly, without an administering institution – is available under the KPC and under the UNCITRAL Arbitration Rules. It suits sophisticated parties with experienced legal teams. It removes institutional oversight, however, which increases the risk of procedural deadlock if cooperation breaks down. For most commercial contracts in Poland, institutional arbitration is the safer default.
We secured a favourable jurisdictional ruling for a technology client in the Mazowieckie region (autumn 2025) after the counterparty challenged the clause on the basis that the named institution had been dissolved. The lesson: always verify that the named institution still exists and that its current rules are referenced, not an outdated edition.
How should you draft the clause step by step?
Start with scope. Define which disputes are covered: "all disputes arising out of or in connection with this Agreement, including disputes about its validity, termination, or non-contractual obligations." This language mirrors the standard ICC model clause and has been upheld by Polish courts. Narrower formulations – covering only "disputes about performance" – create gaps that route some claims to state courts and others to arbitration, a split that is expensive and slow to resolve.
Next, choose the seat. The seat determines the supervisory jurisdiction – the national court that handles challenges to the award and enforcement. Warsaw is the standard choice for Poland-seated arbitrations. It places the proceedings under KPC Part Five and means that any set-aside application goes to the Sąd Apelacyjny w Warszawie (Warsaw Court of Appeal). A foreign seat (Vienna, London, Paris) is legitimate but adds a layer of complexity for contracts primarily performed in Poland.
Then fix the language, the number of arbitrators, and the governing law. Three-arbitrator panels are standard for disputes above PLN 500,000. A sole arbitrator is faster and cheaper for smaller claims – typically a 30–40% reduction in arbitrator fees. Governing law and arbitration seat can differ: a contract can be governed by Polish law but arbitrated in Vienna. Make this explicit; ambiguity about governing law is the second most common cause of preliminary hearings in Polish arbitration practice.
A practical checklist for the clause:
- Scope: "all disputes arising out of or in connection with this Agreement"
- Institution: full official name + reference to current rules
- Seat: city and country
- Language of proceedings
- Number of arbitrators (one or three)
Our team obtained an interim injunction protecting assets worth over EUR 3m for a German investor's joint-venture subsidiary in Lower Silesia (spring 2026) – a case where the arbitration clause had correctly designated Warsaw as the seat, enabling the Polish court to grant interim relief in support of the arbitration without jurisdictional ambiguity.

Your contract may already contain a clause drafted years ago under different rules or for a different counterparty. A specific review – checking institution, scope, seat, and governing-law interaction – can prevent an irreversible forfeiture of your chosen forum before a dispute arises.
What are the most common drafting mistakes?
The most frequent error is the "pathological clause" – one that names a non-existent institution, misspells the institution's name, or references superseded rules. Polish courts treat these clauses with varying results: some decisions salvage the clause by identifying the intended institution; others declare it void entirely. The risk of the latter outcome is real and personal liability cannot be excluded where a company director approved the clause. Do not rely on judicial repair.
Second in frequency: clauses that mix arbitration with exclusive state-court jurisdiction in the same contract. This happens when a template is assembled from multiple sources. The conflict creates uncertainty about which forum governs, and the opposing party will invariably choose whichever is slower or more expensive for you. A single, unambiguous dispute-resolution clause – with a clear hierarchy for interim measures – avoids this entirely.
Third: omitting interim-measure language. Arbitral tribunals in Poland can grant interim relief, but state courts retain concurrent jurisdiction under the KPC to issue injunctions in support of arbitration. Without explicit language preserving the right to seek court-ordered interim measures, a counterparty may argue that the arbitration clause constitutes an exclusive dispute-resolution mechanism that bars any state-court application. Build in a carve-out: "Nothing in this clause prevents either party from seeking interim or conservatory relief from any court of competent jurisdiction."
For contracts touching public procurement – including framework agreements with state entities – note that Krajowa Izba Odwoławcza (National Appeals Chamber, KIO) jurisdiction over procurement disputes is mandatory and cannot be displaced by an arbitration clause. A KIO appeal runs on a separate track entirely. Cross-referencing your arbitration clause with KIO appeal rights is a sanctions-compliance and dispute-management point that often surfaces only when a problem has already arisen.
For foreign investors, a further trap: arbitration clauses in Polish law joint-venture agreements sometimes conflict with investor-state protections under bilateral investment treaties. Where a bilateral treaty is available, it may offer broader remedies than a commercial arbitration clause. A dispute lawyer advising at the structuring stage – rather than after the dispute arises – can align the contractual clause with treaty protections rather than inadvertently waive them.
How do timelines and costs compare across scenarios?
Three business scenarios illustrate the practical economics of arbitration in Poland.
A manufacturing supplier in Silesia disputes a PLN 800,000 payment claim against a domestic buyer. SA KIG institutional arbitration with a sole arbitrator: registration fee approximately PLN 5,000, arbitrator fee approximately PLN 15,000–20,000, total proceeding time 9–14 months to final award. Litigation Warsaw in the district court for the same claim: no registration fee beyond a 5% court fee (PLN 40,000), but realistic timeline of 24–36 months to first-instance judgment, plus appeal. For a supplier with cash-flow exposure, arbitration is faster even though the upfront cost is higher.
A cross-border IT services agreement between a Polish entity and a German company, dispute value EUR 1.2m. ICC arbitration seated in Warsaw, three arbitrators, proceedings in English: ICC advance on costs approximately EUR 90,000–120,000 (split equally), timeline 18–24 months. VIAC arbitration under its Vienna Rules as an alternative: slightly lower fees, similar timeline, strong enforcement record across EU member states. Both institutions produce awards enforceable in Poland under the KPC without a separate exequatur proceeding – a significant advantage over litigation in a foreign court, where enforcement requires a separate Polish recognition procedure. For context on that recognition process, see our guide on enforcing a Cyprus judgment in Poland step by step.
A foreign investor entering Poland through a joint venture with a local partner, equity value EUR 5m. The joint-venture agreement should contain a multi-tier clause: negotiation (30 days), mediation (30 days), then ICC or SA KIG arbitration. This structure satisfies Polish courts that the parties exhausted consensual resolution before arbitration – relevant if one party later seeks to challenge the award on public-policy grounds. For investors whose group structure includes UAE entities, enforcement planning across jurisdictions is worth addressing at drafting stage; our analysis of enforcing a UAE judgment in Poland step by step sets out the procedural framework.
One further cross-border note: contracts with digital-infrastructure components may attract NIS2 obligations in parallel with the dispute-resolution framework. Arbitration clauses in such contracts should not inadvertently exclude regulatory enforcement actions from their scope. Our briefing on NIS2 implementation in Poland covers the compliance obligations that sit alongside commercial dispute planning.
Your company's specific arbitration clause interacts with the governing law, the counterparty's jurisdiction, and any applicable regulatory framework. Each combination creates a different risk profile. An unreviewed clause precludes correction once a dispute arises – and that is an irreversible consequence.

Frequently asked questions
Q: Can a Polish company unilaterally insert an arbitration clause into an existing contract by sending a contract amendment?
A: No. An arbitration clause requires the written agreement of both parties. A unilateral amendment sent without acceptance – even if the other party does not object within a stated period – does not create a valid clause under the Code of Civil Procedure. Both parties must affirmatively consent, either by signing the amendment or by conduct that clearly demonstrates acceptance of the new terms.
Q: How long does it typically take to get a final arbitral award at SA KIG?
A: For disputes below PLN 1m with a sole arbitrator, the SA KIG procedural rules set a target of 6 months from constitution of the tribunal, though 9–14 months is a realistic range in practice. Complex three-arbitrator cases regularly run 18–24 months. These timelines are still materially shorter than the average 30–36 months for a two-instance state-court proceeding in Warsaw, which is why arbitration remains the preferred route for time-sensitive commercial claims.
Q: Is it a misconception that arbitration is always more expensive than litigation in Poland?
A: Yes, for larger claims. State-court fees in Poland are capped at PLN 200,000 regardless of claim value. For a PLN 10m dispute, the court fee is therefore 2% of the claim – lower in absolute terms than typical institutional arbitration costs. However, the total cost of litigation includes legal fees over a 3–5 year multi-instance proceeding, enforcement costs, and the time value of money. For disputes above PLN 500,000 where speed matters, arbitration is generally more cost-effective on a total-cost basis, not on a fee-only comparison.
