A European supplier discovers midway through a long-term delivery contract that its production costs have doubled due to a global shortage of raw materials. The buyer refuses to renegotiate. The supplier turns to Czech contract law for relief – and finds a body of doctrine that is more nuanced, and more demanding, than anything found in comparable civil law systems.
Force majeure and hardship in Czech Republic contract law are governed by the civil code provisions on vyšší moc (force majeure) and změna okolností (change of circumstances). This together form the primary legal responses to business disruption. Force majeure suspends or extinguishes liability for non-performance, while hardship opens a pathway to judicial or negotiated contract modification. Czech courts apply both doctrines strictly, placing the burden of proof firmly on the party claiming relief.
This analysis examines the doctrinal foundations of each doctrine, the gap between the statute and actual court practice. Cross-border implications for international commercial parties. Additionally, the strategic choices available to businesses operating in the Czech market.
Doctrinal foundations: force majeure and hardship under Czech civil law
Czech contract law underwent a fundamental transformation when the current civil code came into force in 2014. The new legislation replaced a fragmented, socialist-era regime with a comprehensive civil law system inspired by comparative European models. The treatment of force majeure and hardship reflects this ambition – but also carries its own interpretive challenges.
Under Czech civil legislation, force majeure operates as a liability exclusion rather than a ground for contract termination. A party that fails to perform an obligation due to a force majeure event is released from the duty to pay damages. The obligation itself, however, remains in force unless the event makes performance permanently impossible – in which case the obligation is extinguished and restitution may become available.
For an event to qualify as force majeure under Czech law, it must satisfy three cumulative conditions. First, the obstacle must arise outside the obligor's sphere of control. Second, it must be unforeseeable at the time the contract was concluded. Third, it must be irresistible – meaning that the obligor could not reasonably have avoided or overcome its consequences. All three elements must be present. Practitioners in Czech Republic consistently observe that courts scrutinise each element separately and with considerable rigour.
The hardship doctrine – referred to in Czech legal literature as the regime of fundamental change of circumstances – operates on a distinct legal basis. It applies where circumstances change so fundamentally that it would be grossly inequitable to require the disadvantaged party to continue performing on the original terms. Unlike force majeure, hardship does not concern an obstacle to performance. The party can still perform; the issue is whether performance remains economically or commercially tolerable.
Czech civil legislation sets out a two-stage response to hardship. In the first stage, the disadvantaged party is entitled to request renegotiation of the contract. This request does not suspend the duty to perform while negotiations are ongoing. a point that trips up many international clients who assume, based on their home jurisdiction's rules, that invoking hardship provides immediate relief. In the second stage, if renegotiation fails or the counterparty refuses to engage, the disadvantaged party may apply to a court. The court has discretion to modify the contractual terms or, in extreme cases, to terminate the contract.
The threshold for triggering the hardship regime is high. A change in market price, fluctuation in currency exchange rates, or a shift in the cost of inputs does not automatically qualify. Czech civil legislation requires that the change be fundamental in character and that it could not reasonably have been anticipated. Where a contract expressly allocates the risk of the relevant type of change to one party. for example. Through a fixed-price clause or a risk allocation schedule. that party cannot subsequently invoke hardship to escape the bargain it made.
Competing court interpretations and the gap between statute and practice
Czech courts – principally the Nejvyšší soud (Supreme Court of the Czech Republic) and the regional appellate courts – have developed a body of case law that, while still relatively young, reveals significant interpretive tensions.
On force majeure, the dominant judicial position is that the doctrine is narrow. Courts in Czech Republic have consistently held that economic hardship, supply chain disruption, and price volatility are foreseeable commercial risks. A business that enters a long-term contract without protective clauses accepts those risks. The mere fact that performance becomes significantly more expensive does not convert an economic disruption into a force majeure event.
There is, however, a divergence in how courts treat events of a genuinely extraordinary nature – such as pandemic-related government restrictions, armed conflict affecting supply routes, or natural disasters of unusual severity. Some courts have accepted that such events, where they directly prevent performance, can satisfy the irresistibility requirement. Others have examined whether the party claiming force majeure took all reasonable steps to mitigate the impact before invoking the doctrine. The Nejvyšší soud has moved toward a position that mere invocation of an extraordinary event is insufficient. The claimant must demonstrate that no reasonable alternative means of performance was available.
On hardship, the case law reveals a further tension. Czech civil legislation uses the concept of gross inequity as the operative standard. Courts have not settled on a uniform definition of what constitutes gross inequity in a commercial context. Some chambers apply an objective economic test: if the value imbalance between the parties' performances exceeds a certain threshold, gross inequity is presumed. Others take a more holistic view, asking whether the overall contractual relationship has been distorted beyond what the parties could have intended.
In practice, a party seeking court intervention under the hardship regime faces several procedural hurdles. The statement of claim – the primary document initiating civil proceedings in Czech courts – must plead the specific change of circumstances and quantify its economic impact with supporting evidence. Courts will reject broadly framed claims that fail to identify the precise moment when circumstances changed and the precise manner in which the change affects performance. Legal experts in Czech Republic recommend that parties document the progression of the hardship event in real time, rather than constructing the evidentiary record retrospectively.
A further practical gap concerns the timing of interim relief. Where a party seeks an interim injunction to suspend its own performance obligations while hardship negotiations or court proceedings are ongoing, Czech civil procedure requires it to demonstrate urgency and the risk of irreparable harm. Courts are reluctant to issue such orders in pure contractual disputes, particularly where the harm alleged is economic rather than physical. The result is that the disadvantaged party typically must continue performing – and incurring losses – throughout the duration of the proceedings.
The tension between the duty to continue performing and the right to seek court modification creates a strategic dilemma. A party that stops performing while waiting for judicial relief exposes itself to a damages claim and potentially to a court filing for breach of contract by the counterparty. A party that continues performing undermines its own argument that the situation is grossly inequitable. Managing this dilemma requires careful legal strategy from the outset. For businesses navigating these challenges, a clear understanding of the corporate dispute resolution options in Czech Republic is essential before any formal step is taken.
Cross-border implications for European and international commercial parties
Czech contract law does not operate in isolation. For European and international businesses, several layers of complexity arise when force majeure or hardship is invoked in a cross-border transaction.
The first question is choice of law. Where a commercial contract between parties in different jurisdictions contains a governing law clause selecting Czech law, Czech civil legislation on force majeure and hardship will apply in full. Where the contract selects a different law – English law, German law, French law – Czech doctrine is displaced. In practice, many supply chain contracts, distribution agreements. Additionally. Joint venture arrangements entered into with Czech counterparties either omit a governing law clause or select the law of the jurisdiction where the Czech party is established. In these cases, Czech law frequently governs by default under applicable EU private international law rules.
The second question is enforcement. Where a foreign party obtains a judgment in its home jurisdiction. arising from a contract dispute that also involves force majeure or hardship issues. and seeks to enforce that judgment in Czech Republic. It must engage the judgment enforcement process under Czech civil procedure rules. The recognition and enforcement of EU Member State judgments in Czech Republic proceeds under applicable EU procedural instruments. Non-EU judgments require separate exequatur proceedings before Czech courts. In both cases, the enforcing party should be aware that Czech courts may examine whether the original judgment was obtained in a proceeding that respected fundamental principles of Czech procedural law.
The third question concerns arbitration. Many commercial contracts involving Czech parties include arbitration clauses referring disputes to the Rozhodčí soud při Hospodářské komoře České republiky (Arbitration Court attached to the Czech Chamber of Commerce). Alternatively. To international institutions such as the ICC or VIAC. Arbitral tribunals seated in Czech Republic apply Czech civil legislation on force majeure and hardship unless the parties have agreed otherwise. International arbitral tribunals seated outside Czech Republic may apply different standards, depending on their mandate and the governing law of the contract.
For European clients specifically, the interaction between Czech hardship doctrine and the UNIDROIT Principles on International Commercial Contracts deserves attention. The UNIDROIT Principles contain a hardship regime that is, in several respects, broader than the Czech statutory model. Where a contract incorporates the UNIDROIT Principles. Alternatively. There, an arbitral tribunal treats them as a source of general commercial principles. A party may have access to hardship relief that would not be available under Czech domestic law alone. Legal experts advise that this gap should be evaluated at the contract drafting stage, not after disruption has occurred.
From a cross-border perspective, the litigation and arbitration practice in Czech Republic requires careful coordination where proceedings run concurrently in multiple jurisdictions. A party that invokes hardship in Czech domestic proceedings while simultaneously defending against a claim in a foreign court must ensure that its positions are consistent. Contradictions between the pleadings in different forums can be used against it – both in terms of credibility and in terms of substantive legal argument.
A further cross-border dimension concerns the impact of EU regulatory measures on force majeure claims. Where an EU-level sanction regime, export control, or emergency regulation directly prevents a party from performing, the force majeure analysis must account for both the Czech statutory requirements and the EU regulatory measure's own terms. Some EU instruments expressly preserve contractual rights. Others do not. Practitioners advise that parties affected by EU regulatory disruption obtain specific legal advice on the interaction between the regulatory measure and their contractual obligations before making any force majeure notification.
For comparison, the hardship regimes in other civil law jurisdictions – notably France, Germany, and Portugal – offer a useful reference point. French civil law underwent a significant reform that introduced an express hardship (imprévision) regime. The German civil code contains analogous provisions on the disruption of the basis of the transaction (Störung der Geschäftsgrundlage). The Czech model sits between these two approaches: more structured than the French regime as originally applied, but less developed in its case law than the German model. Businesses with experience in multiple European markets should not assume that their understanding of hardship in one civil law system maps directly onto Czech doctrine. A comparative analysis of how these doctrines apply across European jurisdictions, including force majeure and hardship in Portugal, illustrates how significant the divergences can be even within a shared European legal tradition.

Strategic recommendations for international businesses
The most effective approach to force majeure and hardship in Czech Republic is preventive. The drafting stage is where international parties have the most control over their legal position. Several strategic measures reduce the risk of being trapped by Czech statutory defaults.
First, contracts governed by Czech law should contain an express force majeure clause that defines the triggering events with specificity. Czech civil legislation does not prohibit parties from expanding or restricting the statutory definition of force majeure. A well-drafted clause can include categories of events – pandemics, regulatory actions, war and political instability, cyberattacks – that might otherwise be disputed under the statutory definition. It can also specify the notification procedure, the required timeline, and the consequences for the contract.
Second, contracts should address hardship directly. Parties can agree on renegotiation mechanisms, price adjustment formulas, or MAC (material adverse change) clauses that activate before the statutory hardship threshold is reached. Czech civil legislation permits such arrangements and enforces them according to their terms. A contractual hardship mechanism avoids the uncertainty and cost of court proceedings.
Third, parties entering long-term contracts in the Czech market should consider including dispute resolution clauses that provide for rapid expert determination or emergency arbitration in the event of a disputed force majeure or hardship claim. Czech civil procedure, while efficient by regional standards, can take months or years to resolve contested contractual disputes at first instance. Where time is critical, an arbitral mechanism with expedited rules preserves commercial relationships and reduces loss.
For parties already in a dispute, the strategic priorities are different. Where a force majeure event has occurred, the party seeking relief should act immediately. Czech civil legislation requires that the affected party notify its counterparty of the force majeure event without undue delay. Failure to notify promptly can result in the loss of the liability exclusion for the period of delay. The notification should be in writing, should specify the nature and extent of the obstacle, and should indicate whether the obstacle is temporary or permanent.
Where hardship is the relevant doctrine, the party seeking relief must initiate renegotiation before applying to a court. A premature application to court – without a prior genuine attempt to renegotiate – will likely be dismissed. The renegotiation request should be made in writing and should set out the changed circumstances, their impact, and the relief sought. If the counterparty ignores the request or refuses without engaging on substance, the requesting party is in a stronger position when it brings the matter before a court.
Throughout any force majeure or hardship process in Czech Republic, contemporaneous documentation is critical. Courts and arbitral tribunals will examine the evidentiary record with care. Emails, board minutes, financial projections, expert reports, and communications with suppliers or regulators all form part of the record. Assembling this evidence after the fact – or, worse, reconstructing it for the purposes of litigation – undermines credibility and can result in adverse findings.
The economics of the decision to litigate also deserve careful analysis. Czech court fees for commercial claims are determined by the value of the claim. Costs follow the event to a significant degree, meaning that the losing party bears a portion of the winner's legal costs. Where the claim relates to contract modification rather than a monetary judgment, the cost-benefit analysis is more complex. Legal fees in Czech Republic for complex commercial litigation start in the range of tens of thousands of euros and can increase substantially for multi-stage proceedings involving expert evidence. Parties should evaluate the total cost of litigation against the value of the relief they are seeking before initiating formal proceedings.
The regulatory outlook and what to monitor
Czech contract law is not static. Several developments at the domestic and European level warrant close attention from businesses with ongoing exposure to Czech-governed contracts.
At the domestic level, Czech legal scholarship and judicial practice continue to develop the doctrinal contours of hardship. The Nejvyšší soud issues periodic judgments that refine the conditions for relief and the standards of proof. Businesses should monitor developments in Czech civil case law, particularly as courts address the aftermath of the pandemic period and ongoing supply chain disruptions. The interpretive questions that arose from these events are still working their way through the Czech judicial system.
At the European level, the EU's evolving regulatory agenda has indirect but significant implications for force majeure analysis. New instruments in the areas of sustainability, supply chain due diligence, AI regulation, and strategic supply security impose obligations that may conflict with contractual commitments. Where compliance with an EU regulatory requirement makes contractual performance more burdensome. or, in extreme cases. Impossible. the force majeure and hardship analysis must be conducted against the backdrop of both the contractual terms and the regulatory obligation.
The interaction between Czech insolvency law and contract law is also a monitoring priority. Where a counterparty in a hardship dispute becomes insolvent, the contractual dispute transforms into an insolvency proceeding. Czech insolvency legislation contains specific rules on the treatment of executory contracts, which may override the civil law hardship analysis entirely. Identifying the early indicators of counterparty financial distress – and adjusting contractual strategy accordingly – is a critical risk management function for any business with significant Czech contractual exposure.
Finally, the growing use of technology and AI-generated contract terms raises new questions for force majeure and hardship analysis. Where a force majeure or MAC clause is drafted by an automated system without careful adaptation to Czech law requirements, gaps in coverage may not be apparent until disruption occurs. Legal experts in Czech Republic advise that algorithmically generated contract language be reviewed by qualified Czech law practitioners before execution.
Frequently asked questions
Q: Can a business in Czech Republic invoke force majeure simply because its costs have increased significantly?
A: No. Under Czech civil legislation, an increase in cost – even a severe one – does not by itself constitute force majeure. The doctrine requires an external obstacle that makes performance objectively impossible, not merely more expensive. A party whose costs have increased substantially should instead consider whether the hardship regime applies, and should review its contract for any express price adjustment or MAC clause before taking any formal step.
Q: How long do Czech court proceedings for a hardship claim typically take, and what are the costs involved?
A: First-instance proceedings before Czech district or regional courts in a contested commercial hardship matter typically take between one and two years, depending on the complexity of the evidence and the court's caseload. Appeals to the appellate chamber can add a further year or more. Legal fees for complex commercial litigation in Czech Republic start in the range of tens of thousands of euros. Parties are generally advised to pursue genuine renegotiation and alternative dispute resolution before resorting to court proceedings, both to satisfy the statutory precondition for court intervention and to manage costs.
Q: Does invoking hardship in Czech Republic suspend the duty to continue performing the contract?
A: This is a common misconception. Under Czech civil legislation, the request for renegotiation and, subsequently, the application to court do not automatically suspend the affected party's obligation to perform. Unilaterally ceasing performance while a hardship dispute is pending exposes the party to a claim for breach of contract. In exceptional cases an interim injunction may be available, but Czech courts apply a strict test for such relief. Engaging a lawyer in Czech Republic with experience in commercial contract disputes is advisable before deciding whether to continue or suspend performance.
