Learn how force majeure works in Turkish contracts, including impossibility, hardship, delay, termination, notice duties, consumer-law limits, and practical force majeure clause drafting under Turkish law.
Introduction
Force majeure in Turkish contracts is one of the most misunderstood issues in cross-border and domestic transactions. Parties often use the phrase as if it were a single, universal legal defense that automatically suspends or excuses performance whenever an extraordinary event occurs. Turkish law is more structured than that. As a matter of statutory design, the Turkish Code of Obligations does not solve the entire issue through one standalone “force majeure” article. Instead, it addresses the consequences usually associated with force majeure through several different mechanisms, especially freedom of contract, invalidity limits, non-performance, default, impossibility of performance, partial impossibility, and excessive difficulty of performance.
That structure is commercially important. Under Turkish law, the right answer depends on the type of event and the type of impact. Some events may make performance objectively impossible and extinguish the obligation. Others may not make performance impossible, but may transform the economic balance so radically that the debtor can ask the court to adapt the contract or, if adaptation is not possible, to allow rescission or termination. In other cases, the event may simply delay performance, in which case default, notice, cure periods, and election of remedies become decisive.
For that reason, force majeure in Turkish law is best understood as a contractual and remedial problem, not as a single magic label. A party that simply says “this was force majeure” has not yet answered the real legal questions. Was performance impossible, partially impossible, excessively burdensome, or merely delayed? Did the contract itself allocate the risk? Was notice given promptly? Is the agreement a one-off reciprocal contract or a continuous-performance relationship? Those questions determine whether the party may be excused, whether the contract may be adapted, and whether the other side may terminate or claim damages.
This guide explains force majeure in Turkish contracts in practical English. It covers the statutory framework, the role of contractual force majeure clauses, the difference between impossibility and hardship, the effect on delay and termination rights, the notice-and-mitigation burden, and the main drafting risks for businesses using Turkish-law contracts.
There Is No Single General Force Majeure Article, but There Is a Clear Legal Framework
Turkish law does not present force majeure through one general code article that defines the concept exhaustively for all contracts. Instead, the Turkish Code of Obligations lays down a broader framework. Article 26 allows the parties to determine contractual content freely within the limits prescribed by law, while Article 27 invalidates contracts that violate mandatory rules, morality, public order, personal rights, or involve an impossible subject matter. Article 112 governs liability where the obligation is not performed at all or not properly performed. Articles 117 to 126 regulate debtor default and its consequences. Articles 136 and 137 deal with impossibility and partial impossibility. Article 138 regulates excessive difficulty of performance. Taken together, these provisions form the legal backbone of force majeure analysis in Turkey.
This matters because Turkish-law force majeure disputes are usually resolved by fitting the event into one of those statutory categories, while also reading the contract itself closely. In other words, Turkish law usually asks not “Was there force majeure in the abstract?” but rather “What legal consequence follows from this event under the contract and the Code?” That approach makes force majeure analysis more precise, but it also means that vague clause drafting can create serious litigation risk.
Freedom of Contract Allows Force Majeure Clauses, but Only Within Legal Limits
The starting point for contractual drafting is Article 26 of the Turkish Code of Obligations. It states that the parties may freely determine the content of their contract within the legal limits. That means Turkish-law contracts may contain detailed force majeure clauses allocating risk, setting notice periods, defining covered events, regulating suspension, distributing extra costs, or identifying termination rights. But Article 27 immediately reminds the parties that contractual freedom is not unlimited. Clauses contrary to mandatory law, public order, morality, personal rights, or involving impossible subject matter are definitively invalid.
In practice, this means Turkish law usually respects a carefully drafted force majeure clause, but the clause cannot override mandatory legal consequences in every possible way. Nor can it be drafted so broadly that it destroys the basic structure of the bargain or attempts to immunize conduct that the law does not permit the parties to excuse. For commercial parties, the safer approach is to use force majeure clauses to clarify risk allocation rather than to assume that a broad sentence like “all extraordinary events excuse performance” will solve every future dispute.
General Liability for Non-Performance Remains the Background Rule
Before a party can rely on force majeure in Turkish law, the background rule on contractual liability must be understood. Article 112 states that if an obligation is not performed at all or is not performed properly, the debtor must compensate the creditor’s loss unless the debtor proves that no fault can be attributed to it. Article 114 adds that the debtor is generally responsible for every degree of fault, subject to the nature of the transaction. This means the basic legal position is still one of liability for breach unless the debtor can bring the case within a recognized excuse, such as non-attributable impossibility or another applicable statutory or contractual defense.
That is why force majeure arguments matter so much in Turkish practice. They are often raised to break the normal chain that starts with non-performance and leads to damages. But the event must be analyzed legally, not rhetorically. Simply proving that market conditions worsened or that performance became inconvenient is not enough by itself to displace Article 112. The party usually needs to show either that performance became impossible for reasons outside its responsibility, that the contract should be adapted or exited under Article 138, or that the contract itself validly reallocated the risk through a force majeure clause.
Impossibility of Performance: The Strongest Force Majeure Path
The clearest statutory route for a successful force majeure defense is Article 136 of the Turkish Code of Obligations. It states that if performance becomes impossible due to reasons for which the debtor cannot be held responsible, the obligation is extinguished. In reciprocal contracts, the party released from performance must return what it has already received under unjust-enrichment rules and loses the right to demand the counter-performance that has not yet been rendered. The article also imposes a separate duty: if the debtor does not inform the creditor without delay that performance became impossible and does not take the necessary measures to prevent the loss from increasing, the debtor must compensate the resulting damage.
This is one of the most important rules for force majeure in Turkish contracts. If an event truly makes performance impossible and the debtor is not legally responsible for that event, the obligation ends. But Article 136 does not excuse silence or passivity. Even where the principal obligation is extinguished, the debtor may still face liability if it failed to notify the creditor promptly or failed to limit avoidable damage. In Turkish practice, a force majeure defense is therefore strongest when it is paired with immediate written notice, clear evidence of impossibility, and documented mitigation efforts.
Partial Impossibility Does Not Always End the Entire Contract
Article 137 regulates partial impossibility. It provides that where performance becomes partially impossible for reasons for which the debtor cannot be held responsible, the debtor is released only from the impossible part of the obligation. However, if it is clear that the parties would not have entered into the contract had they foreseen this partial impossibility, the entire obligation ends. In reciprocal contracts, if one party’s obligation becomes partially impossible and the creditor accepts partial performance, the counter-performance is reduced proportionally. If the creditor does not accept such partial performance, or the counter-performance is indivisible, the rules on total impossibility apply.
This matters greatly for modern supply chains and service contracts. Not every disruptive event destroys the entire bargain. Sometimes only part of the promised performance becomes impossible. Turkish law therefore forces the analysis to stay granular. A party cannot automatically treat every supply interruption or operational breakdown as a basis for ending the whole contract. The legal question is whether the impossible part can be separated, whether the creditor must accept partial performance, and whether the contract still makes commercial sense after proportional adjustment.
Excessive Difficulty of Performance: The Hardship Route
Many events described commercially as force majeure do not make performance impossible in the strict sense. They make performance radically harder, more expensive, or commercially distorted. Article 138 of the Turkish Code of Obligations is designed for that situation. It applies where an extraordinary event, not foreseen and not expected to be foreseen at the time of contracting, arises from a cause not attributable to the debtor, changes the facts existing at the time of contract formation to such an extent that demanding performance would be contrary to the rules of honesty, and the debtor has either not yet performed or has performed while reserving its rights arising from the excessive difficulty. In that case, the debtor may ask the judge to adapt the contract to the new conditions and, if adaptation is not possible, may rescind the contract; in continuous-performance contracts, the debtor generally uses termination instead of rescission. The article also expressly states that it applies to foreign-currency debts.
This is a crucial distinction in Turkish law. Impossibility under Article 136 extinguishes the obligation where performance cannot be carried out at all for non-attributable reasons. Excessive difficulty under Article 138 does not automatically extinguish the contract. It first opens the door to judicial adaptation. Only if adaptation is not possible does the law move toward rescission or termination. That makes Article 138 highly relevant for long-term commercial contracts affected by extraordinary shocks, but it also means that not every serious economic disruption will excuse performance immediately.
Delay Is Not the Same as Force Majeure
Some disruptive events do not make performance impossible and do not satisfy the hardship threshold. They simply delay performance. In that situation, the Turkish default regime becomes central. Article 117 states that the debtor of a due obligation falls into default upon creditor notice. If the day of performance was jointly fixed, or was properly determined by a contractually reserved right, the debtor falls into default automatically when that day passes. Article 118 then provides that a debtor in default must compensate the loss caused by late performance unless it proves absence of fault.
This means that a party cannot safely rely on the vocabulary of force majeure if the real legal problem is just delay. Under Turkish law, delay can still trigger default, delay damages, and later termination rights unless the contract validly suspends those consequences or the debtor can bring the case within a recognized statutory excuse. The distinction matters because many force majeure clauses are drafted broadly, while the underlying event in reality only affects timing. If the clause is unclear, the dispute may shift quickly from “force majeure” to ordinary default law.
Cure Periods, Election of Remedies, and Contract Ending Rights
Where a disruptive event causes continued non-performance in a reciprocal contract, Turkish law may require the creditor to choose a remedial path. Article 123 states that where one party to a reciprocal contract falls into default, the other party may grant an appropriate additional period for performance or ask the court to grant one. Article 124 lists cases where no additional period is necessary, including where granting time would clearly be ineffective, where performance has become useless for the creditor due to the delay, or where the contract shows that late performance would no longer be accepted. Article 125 then gives the creditor election rights: it may demand performance and delay damages, or immediately declare that it waives performance and delay damages and instead seek damages for non-performance or rescind the contract. In continuous-performance contracts, Article 126 allows the creditor to terminate and claim the damage caused by the relationship ending before its intended duration.
These articles matter for force majeure disputes because the same disruptive event may affect the debtor’s excuse argument and the creditor’s exit rights at the same time. Even if the debtor insists that the event was extraordinary, the creditor may argue that performance became useless, that no extra cure period is necessary, and that rescission or termination is now justified. In Turkish practice, force majeure is therefore often litigated together with default, cure, and termination. The stronger contract is the one that coordinates those concepts clearly instead of mentioning force majeure in isolation.
Notice and Mitigation Are Not Optional
One of the most overlooked risks in Turkish force majeure practice is the notice duty. Article 136 expressly requires the debtor to inform the creditor without delay if performance has become impossible and to take the measures necessary to prevent the loss from increasing. If the debtor fails to do so, it must compensate the resulting damage. Even outside strict impossibility, Turkish-law force majeure clauses are usually safer when they require prompt written notice, supporting evidence, and continuing updates. That contractual drafting approach fits the statutory logic of Article 136.
This is why silence is dangerous. A party may ultimately have a strong substantive argument that the event was beyond its control, but still lose ground because it waited too long, gave vague notice, or failed to document mitigation efforts. In Turkish contract disputes, good force majeure practice is operational as much as legal: notify early, describe the event precisely, explain the causal impact on performance, reserve rights explicitly, and preserve evidence of mitigation.
Consumer Contracts Require Extra Caution
When force majeure language appears in consumer contracts, Turkish law adds a further layer of control. Article 5 of the Consumer Protection Law defines unfair terms as non-negotiated contractual terms that create an imbalance against the consumer contrary to good faith, provides that such terms are definitively invalid, and states that if a standard term was prepared in advance and the consumer could not influence its content, it is deemed not to have been negotiated. The burden of proving individual negotiation lies with the drafter. Written consumer terms must also be clear and understandable, and ambiguous terms are interpreted in the consumer’s favor.
This is highly relevant for force majeure clauses in platform terms, subscription agreements, service terms, and mass-market online sales. A clause that gives the trader a broad, one-sided excuse for non-performance while leaving the consumer with no corresponding rights may face consumer-law scrutiny as an unfair term. In other words, Turkish law does not prevent consumer contracts from addressing extraordinary events, but such clauses must be drafted transparently and balanced enough to survive unfair-term review.
Distance contracts create an additional compliance layer. Article 48 of the Consumer Protection Law defines distance contracts, while the Distance Contracts Regulation sets out a dedicated framework for pre-contract information, performance, withdrawal, and exclusions from the regime. That means a force majeure clause in a consumer e-commerce contract is never assessed in isolation; it sits inside a broader mandatory statutory environment.
Drafting Force Majeure Clauses Under Turkish Law
A strong Turkish-law force majeure clause should do more than list natural disasters and wars. It should specify what the event must do legally: make performance impossible, prevent performance temporarily, or trigger hardship-type renegotiation. It should distinguish suspension from termination, define the notice period, require reasonable mitigation, regulate evidentiary support, and clarify what happens to accrued obligations, partial performance, and ongoing payment duties during the disruption. That drafting approach aligns much better with the structure of Articles 136, 137, and 138 than a vague clause saying only that “all extraordinary events excuse the parties.”
It is also wise to coordinate the force majeure clause with the contract’s default and termination provisions. If the agreement has hard deadlines, cure periods, or termination triggers, the clause should explain how a force majeure event affects those mechanisms. Otherwise, the parties may end up litigating whether the event merely suspended time, eliminated fault, justified adaptation, or left ordinary default remedies intact. Turkish law already provides a detailed structure for those questions, so careful drafting should build on that structure rather than work against it.
Main Risks for Businesses
The first major risk is overbreadth. A force majeure clause that is drafted too broadly may create uncertainty rather than protection, especially if it does not distinguish impossibility from economic hardship or temporary delay. The second risk is under-definition. If the contract lists events but says nothing about notice, mitigation, suspension length, adaptation, or termination, the dispute will quickly fall back onto the statutory framework, often in a way the parties did not fully anticipate. The third risk is one-sided consumer drafting, which may expose the clause to unfair-term control.
A fourth risk is poor timing behavior after the event occurs. Turkish law’s notice-and-mitigation logic makes operational response legally significant. A party that reacts late, performs inconsistently, or communicates ambiguously may weaken its own defense. In force majeure disputes under Turkish law, the legal position is often shaped not only by the event itself, but by what the party did in the days and weeks that followed.
Conclusion
Force majeure in Turkish contracts is best understood through consequences, not slogans. Turkish law allows parties to allocate extraordinary-event risk by contract under the freedom-of-contract principle, but it also supplies a detailed statutory framework that distinguishes non-performance, delay, impossibility, partial impossibility, and excessive difficulty of performance. Article 136 governs non-attributable impossibility. Article 137 addresses partial impossibility. Article 138 governs hardship and judicial adaptation. Articles 117 to 126 control default, cure, election of remedies, rescission, and termination.
The practical takeaway is that a party invoking force majeure under Turkish law should first classify the event correctly, then read the contract alongside the statute, then act quickly on notice and mitigation. A party drafting a Turkish-law force majeure clause should match the clause to the Code’s remedial architecture instead of relying on generic boilerplate. That is the difference between a clause that looks impressive and a clause that actually works when the disruption arrives.
FAQ
Does Turkish law have one general force majeure definition?
Not in one single general code article. As a structural matter, Turkish contract law addresses force-majeure-type consequences through several provisions, especially Articles 112, 117 to 126, and 136 to 138 of the Turkish Code of Obligations, together with the parties’ contractual risk allocation under Articles 26 and 27.
What happens if performance becomes impossible for reasons outside the debtor’s responsibility?
Article 136 states that the obligation is extinguished. In reciprocal contracts, the released party must return what it received under unjust-enrichment rules and loses the right to claim the unperformed counter-performance. The debtor must also notify the creditor without delay and take steps to prevent the loss from increasing.
What if only part of the contract becomes impossible?
Article 137 provides that the debtor is released only from the impossible part, unless it is clear that the parties would not have entered into the contract had they foreseen the partial impossibility. In reciprocal contracts, if the creditor accepts partial performance, the counter-performance is reduced proportionally.
What if performance is still possible but has become extremely difficult?
Article 138 addresses excessive difficulty of performance. If the statutory conditions are met, the debtor may ask the judge to adapt the contract to the new conditions and, if adaptation is not possible, may rescind the contract or, in continuous-performance contracts, terminate it. The article also applies to foreign-currency debts.
Does a force majeure event automatically prevent default?
Not necessarily. If the event does not legally extinguish or adapt the obligation, ordinary default rules may still apply. Article 117 governs when default begins, while Articles 123 to 126 regulate cure periods, election of remedies, rescission, and termination in reciprocal and continuous-performance contracts.
Can force majeure clauses be challenged in consumer contracts?
Yes. Under Article 5 of the Consumer Protection Law, non-negotiated terms that create an imbalance against the consumer contrary to good faith are definitively invalid, and ambiguous written terms are interpreted in the consumer’s favor.
Why is notice so important under Turkish law?
Because Article 136 expressly states that if the debtor does not notify the creditor without delay that performance has become impossible and does not take the necessary measures to prevent the increase of loss, the debtor must compensate the resulting damage.
