A European supplier halts delivery. A construction project stalls for months. A hotel chain cancels long-term booking contracts mid-season. In each scenario, the counterparty reaches for the same two doctrines: force majeure and hardship. In Greece, both doctrines exist – but their application is more contested, more nuanced, and more consequential than a plain reading of the civil code suggests.
Force majeure and hardship in Greece are governed by Greek civil legislation, which recognises both the impossibility of performance and the right to seek judicial adjustment of contracts rendered excessively onerous by supervening events. The doctrines are available in principle to any contracting party but require strict factual and legal conditions to activate. Successful invocation typically depends on the nature of the event, the foreseeability analysis performed by Greek courts, and whether the affected party acted promptly to document and assert its position.
This analysis examines the doctrinal foundations of both doctrines under Greek law, maps the gap between the written rules and actual court behaviour. Identifies the strategic choices available to international businesses operating in Greece. Additionally, draws out the cross-border implications for European clients caught between Greek contract law and foreign governing-law clauses.
Doctrinal foundations: how Greek civil legislation frames impossibility and hardship
Greek contract law rests on the Greek Civil Code, a codified civil law instrument drawing heavily on the German pandectist tradition. Two distinct but related mechanisms address disrupted contractual performance.
The first mechanism is vis maior (force majeure) – rendered in Greek legal discourse as ανωτέρα βία (superior force). Under Greek civil legislation, a debtor is released from an obligation when performance becomes objectively impossible due to a cause not attributable to the debtor. Three cumulative elements must be satisfied. The event must be genuinely unforeseeable at the time of contracting. It must be unavoidable even with the exercise of reasonable care. And it must render performance impossible – not merely more difficult or more expensive.
The second mechanism is hardship, addressed in Greek civil legislation through the doctrine of αλλαγή βάσης της δικαιοπραξίας (change in the basis of the legal act). This doctrine, rooted in the principle of good faith that permeates Greek civil legislation. Allows a court to adjust or terminate a contract when supervening circumstances fundamentally alter the underlying assumptions on which the parties contracted. Unlike force majeure, hardship does not require impossibility. It requires a severe and disproportionate disruption of the contractual equilibrium.
These two instruments operate along a spectrum. Force majeure triggers automatic release from performance. Hardship triggers a right to renegotiate or judicially revise the contract. In practice, the boundary between them blurs – and Greek courts have not always maintained a clean doctrinal separation.
Under Greek civil litigation procedure, a party wishing to invoke either doctrine must raise it by way of a defence or counterclaim in the relevant proceedings. A statement of claim asserting hardship adjustment must plead the supervening facts with specificity. Identify the contractual basis assumed by the parties at the time of formation. Additionally, demonstrate a causal link between the supervening event and the disrupted equilibrium. Greek civil procedure rules require this material to appear in initial pleadings. Late introduction is routinely rejected by courts, with serious consequences for parties that delay in assembling their position.
Competing court interpretations: where Greek doctrine meets commercial reality
The tension in Greek case law runs along a familiar fault line: courts inclined toward contractual stability versus courts willing to intervene in the name of equity and good faith. Both approaches are present in the decisions of the Άρειος Πάγος (Areios Pagos), the Supreme Court of Greece, and in the appellate decisions of the Εφετεία (Courts of Appeal).
On force majeure, the Areios Pagos has consistently applied a stringent foreseeability standard. If the event causing disruption could have been anticipated by a reasonably prudent contracting party – even if only in general terms – the doctrine does not apply. Courts have declined to treat economic crises, regulatory changes. Alternatively. Supply chain disruptions as force majeure events unless the affected party can demonstrate that the specific disruption was genuinely unforeseeable and that performance became impossible, not merely more costly.
This is where practice diverges most sharply from theory. International clients frequently misread the Greek force majeure doctrine by analogising to common law frustration or to more permissive civil law systems. Greek courts have shown a strong preference for contractual enforcement. Even extended periods of government-mandated closure – as seen during pandemic-related restrictions – did not automatically qualify as force majeure in commercial contracts. Courts examined whether performance was truly impossible or whether the obstacle was temporary, with performance merely deferred rather than extinguished.
For hardship, the divergence is different in character. Greek civil legislation grants courts explicit authority to adjust contracts. But the case law reveals that courts exercise this authority conservatively. The threshold for demonstrating that the change in circumstances was extraordinary – rather than a normal commercial risk allocated by the parties themselves – is high. Courts have rejected hardship claims where the risk in question was one that a sophisticated commercial party could have foreseen or contractually allocated.
A recurring tension concerns contracts with price adjustment clauses or indexation mechanisms. Where such clauses exist, courts consistently hold that the parties have already addressed the risk of price fluctuation. Hardship claims premised on inflation, currency movement, or commodity price increases are substantially weakened by the presence of these clauses. even where the actual price movement far exceeds what the clause was designed to absorb.
In commercial litigation strategy, this distinction matters enormously. A party mounting a court filing asserting hardship must demonstrate not only that circumstances changed dramatically but also that the changed circumstances were external to any risk the contract itself allocated. This two-stage analysis – contractual risk allocation followed by supervening event severity – defines the practical threshold for a viable hardship claim before Greek courts.
For clients considering an corporate dispute in Greece, the starting point must always be a careful analysis of the contract's risk allocation architecture before any doctrinal argument is advanced.
The gap between statute and practice: what international clients underestimate
Three gaps between the written law and actual Greek court behaviour deserve particular attention from international businesses.
The timing gap. Greek civil procedure is unforgiving on the timing of defences. A party invoking force majeure or hardship must do so at the first available procedural opportunity. Failure to raise the defence in initial pleadings – whether in a statement of claim or in the response to one – may result in the argument being treated as waived. Many international clients, accustomed to jurisdictions that permit late amendment of pleadings, lose this argument not on the merits but on procedural grounds. The lesson is that factual investigation and legal strategy must begin immediately upon disruption – not when proceedings are already underway.
The evidence gap. Greek courts require concrete evidence of the impossibility or the disrupted contractual equilibrium. Abstract assertions that performance was rendered difficult are insufficient. Practitioners in Greece emphasise the importance of contemporaneous documentation: communications acknowledging the disruption, expert evidence on market conditions, and records of mitigation efforts. A party that fails to document its position at the time of disruption will struggle to reconstruct it months later in court.
The interim protection gap. In certain disputes. A party may seek an interim injunction. referred to in Greek procedural law as ασφαλιστικά μέτρα (precautionary measures). to preserve the status quo while the main hardship claim is resolved. This mechanism is available under Greek civil procedure rules but requires the applicant to demonstrate urgency and a prima facie case. Courts do not automatically grant interim relief simply because a party has asserted hardship. The burden of demonstrating both elements rests on the applicant, and the time available to assemble the application is short. Failing to obtain interim protection in a time-sensitive commercial dispute can cause irreversible harm while the primary proceedings work their way through the Greek court system.
Greek courts can be slow in commercial matters. First-instance decisions in complex commercial disputes frequently take twelve to twenty-four months. Appeals extend the timeline further. A party relying on hardship adjustment as a live commercial remedy – rather than as a defence against a claim – must factor this timeline into its strategy. In many cases, negotiated adjustment during the pendency of proceedings is more commercially rational than waiting for a judicial outcome.
There is also a structural issue with judgment enforcement after a successful hardship or force majeure determination. A Greek court decision adjusting or terminating a contract does not automatically resolve the parties' financial positions. Secondary disputes about restitution, unjust enrichment, and damages frequently follow the primary determination, adding further litigation layers. International clients should plan for this multi-stage process from the outset.

Cross-border implications for European clients
Force majeure and hardship disputes in Greece rarely involve purely domestic parties. European businesses operating supply chains through Greece, investing in Greek real estate. Alternatively. Contracting with Greek counterparties face an additional layer of complexity: the interaction between Greek civil law doctrine and the governing law of their contracts.
Where a contract is governed by Greek law – whether by express choice or by default application of EU private international law rules – Greek civil legislation applies in full. The doctrines described above govern. A German buyer contracting with a Greek supplier under Greek law cannot import the more permissive German Wegfall der Geschäftsgrundlage (frustration of purpose) doctrine simply because it might produce a more favourable result.
Where the contract is governed by foreign law – English law is common in international commercial contracts with Greek parties – the force majeure and hardship analysis applies the foreign law. But the procedural reality of Greek courts applies regardless. If the dispute is litigated in Greece, the statement of claim, court filing procedures, interim injunction mechanism, and judgment enforcement rules are all governed by Greek civil procedure. The substantive law may be English; the procedural environment remains Greek. This duality is a frequent source of strategic error by international counsel who focus on substantive law without adequately accounting for the Greek procedural context.
A related issue arises in arbitration. Many commercial contracts with Greek parties – particularly in construction, energy, and infrastructure – contain arbitration clauses referring disputes to ICC, LCIA, or other international arbitral bodies. In those cases, the arbitral tribunal applies the governing law of the contract to the force majeure and hardship analysis. But interim relief – particularly urgent preservation orders – may need to be sought from Greek courts in parallel with or prior to arbitral proceedings. Understanding the interaction between the arbitral process and the Greek ασφαλιστικά μέτρα mechanism is therefore essential for internationally active parties.
EU law adds a further dimension. In cross-border supply contracts within the EU, sector-specific European legislation – particularly in agriculture, energy, and digital services – may impose statutory obligations that interact with force majeure clauses. A force majeure clause that would ordinarily excuse performance under Greek civil law may be overridden by a mandatory EU legislative provision placing the risk of supply disruption on the supplier. European clients should map their contractual force majeure provisions against applicable EU sector legislation before assuming the clause operates as written.
The comparison with other civil law systems in Europe is instructive. Portuguese contract law, for example, addresses hardship through a mechanism that shares doctrinal roots with the Greek approach but has developed along different judicial lines. Understanding these comparative dimensions matters for groups operating across multiple EU jurisdictions. For a parallel analysis of how these doctrines operate in another European civil law system, our deep analysis of force majeure and hardship in Portugal offers a useful comparator.

Strategic recommendations for businesses facing disruption in Greece
The practical implications of the analysis above translate into a set of strategic recommendations for businesses operating under Greek-law contracts or litigating force majeure and hardship claims in Greece.
Act immediately on disruption. The most damaging mistake in Greek contract disputes is delay. When a supervening event occurs. whether a regulatory shutdown, a supply chain failure, or an extreme price movement – the affected party should immediately document the event, its consequences, and the steps taken to mitigate. This contemporaneous record is the foundation of any subsequent court filing. A party that begins documenting six months after disruption is already at a disadvantage.
Analyse contractual risk allocation before invoking the doctrine. Before raising force majeure or hardship, map the contract's own risk allocation. Which party bears the risk of price movements? Is there a specific force majeure clause, and if so, does the supervening event fall within its defined triggers? Greek courts treat detailed contractual force majeure clauses as comprehensive allocations of risk. If the clause does not cover the event, the court will look to whether the parties' omission was deliberate. Arguing around a well-drafted clause requires careful preparation.
Assess the realistic prospects of interim protection. Where the commercial stakes justify it, an application for precautionary measures under Greek civil procedure can preserve the status quo while the main dispute is resolved. This is particularly relevant where a counterparty is seeking to enforce payment, terminate a contract, or call on a performance bond. A well-constructed interim injunction application, supported by evidence of urgency and a prima facie case, can prevent irreversible harm during the litigation period.
Consider negotiated adjustment as a parallel track. Given the timelines of Greek commercial litigation. Negotiated contract adjustment. whether through formal renegotiation or through a structured settlement. frequently delivers a better commercial outcome than a judicial determination. Greek courts generally look favourably on evidence that the asserting party sought renegotiation before resorting to litigation. Such evidence also strengthens the good-faith dimension of a hardship claim.
Address arbitration clauses early. If the contract contains an arbitration clause, determine whether the forum is appropriate for the dispute at hand. International arbitration offers procedural advantages – including speed, neutrality, and enforceability under the New York Convention – that may outweigh the costs of pursuing the dispute in that forum. If Greek courts retain jurisdiction, ensure that any parallel arbitral strategy is coordinated with the Greek procedural timeline from the outset.
Distinguish force majeure from hardship in pleadings. Greek courts are sensitive to the distinction between impossibility and excessive onerousness. A pleading that conflates the two doctrines risks being rejected on doctrinal grounds. The statement of claim or defence should clearly articulate which doctrine is being invoked. Set out the specific legal test applicable to that doctrine under Greek civil legislation. Additionally, map the facts onto the legal elements with precision. Vague assertions of "changed circumstances" do not survive Greek judicial scrutiny.

Outlook: regulatory trajectory and what to monitor
The Greek legal system has faced significant stress-testing of its force majeure and hardship doctrines over the past decade. The financial crisis, austerity measures, pandemic-related restrictions, and energy market volatility have each generated waves of contract disputes that have tested the doctrinal boundaries established by earlier case law.
The direction of travel in Greek courts has been cautious. The Areios Pagos has not dramatically expanded the scope of either doctrine in response to recent crises. The prevailing judicial approach continues to emphasise contractual enforcement and a high threshold for intervention. This reflects a broader judicial philosophy that treats contractual certainty as a prerequisite for commercial confidence – a position that aligns with the Greek economy's need to attract foreign investment and cross-border commercial relationships.
Legislative reform is a background risk. Greek civil legislation has not been comprehensively revised in several decades. Proposals for modernisation have circulated within academic and practitioner communities, and European legislative initiatives – particularly in digital services and platform regulation – are creating pressure on Greek legislators to update specific contractual regimes. Businesses with long-term Greek-law contracts should monitor legislative developments that could affect the statutory basis of their force majeure or hardship provisions.
The energy sector deserves particular attention. Greece's position as a transit and storage hub for natural gas. Additionally, its growing role in renewable energy infrastructure. Is producing a new generation of long-term contracts exposed to significant commodity price volatility and regulatory uncertainty. Force majeure and hardship claims in energy contracts present their own distinct issues. including the interaction between contractual clauses and EU energy market legislation – that require sector-specific analysis beyond the general civil law framework.
Finally, the increasing prevalence of AI-generated contract templates and automated compliance tools raises a new practical concern. Contracts formed using standardised clauses that have not been reviewed for compliance with Greek civil law specifics may contain force majeure provisions that operate very differently from what the parties intended. A force majeure clause drafted for an English-law contract and transposed unreviewed into a Greek-law agreement may be interpreted by a Greek court in ways that diverge sharply from the parties' expectations. Legal review at the contract formation stage – not only at the dispute stage – is essential.
Frequently asked questions
Q: How long does a force majeure or hardship dispute typically take to resolve before Greek courts?
A: First-instance proceedings in commercial disputes in Greece frequently take between twelve and twenty-four months to produce a judgment. Appeals to the Court of Appeal and further review by the Areios Pagos can extend the overall timeline to several years. Parties seeking faster resolution should consider whether their contract provides for arbitration or whether a negotiated settlement is feasible alongside litigation.
Q: Is it a common misconception that any government-imposed restriction automatically triggers force majeure under Greek law?
A: Yes – this is one of the most widespread misconceptions among international clients. Greek courts examine not only whether a government restriction occurred but also whether performance became genuinely impossible as a result, and whether the restriction was unforeseeable at the time of contracting. Temporary restrictions that delayed rather than permanently prevented performance have frequently been held insufficient to activate force majeure. The doctrine requires objective impossibility, not merely increased difficulty or reduced commercial viability.
Q: Can a lawyer in Greece obtain interim injunctive relief to prevent a counterparty from enforcing a contract while a hardship claim is pending?
A: Greek civil procedure provides a mechanism for precautionary measures, which can include orders preserving the status quo or preventing enforcement of contractual rights during the pendency of main proceedings. However, the applicant must demonstrate both urgency and a prima facie legal basis for the claim. Engaging a lawyer in Greece with experience in both the substantive doctrine and the procedural requirements for interim relief is essential to mount a credible application within the available time.
