Learn how termination of contracts works under Turkish law, including rescission, termination with notice, immediate termination for just cause, hardship, lease termination, service contracts, consumer withdrawal rights, and the legal consequences of ending a contract in Turkey.
Introduction
Termination of contracts under Turkish law is not governed by a single, simple rule. Turkish law uses different mechanisms depending on the type of contract, the nature of the breach, the duration of the contractual relationship, and whether the contract is a one-off exchange or a continuing performance arrangement. In practice, this means that “termination” in English may correspond to different Turkish-law concepts such as dönme for rescission from a reciprocal contract, fesih for termination of a continuing relationship, expiry of a fixed term, or statutory withdrawal rights in consumer contracts. The main legal framework is the Turkish Code of Obligations No. 6098, with additional rules in consumer law and commercial procedure.
That distinction matters because Turkish law does not treat every end-of-contract scenario the same way. A contract may end automatically because its agreed term expires. It may be rescinded because one party fell into default in a reciprocal contract. It may be terminated prospectively because the agreement is based on continuing performance. It may be ended immediately for just cause. In some cases, a contract may also be adapted or unwound because extraordinary circumstances made performance excessively burdensome. Each route produces different consequences in relation to future obligations, restitution, damages, notice periods, and procedural steps.
For businesses, landlords, tenants, employers, service providers, investors, and consumers, the real issue is therefore not only whether a contract can be ended, but how it must be ended under Turkish law and what legal consequences follow. A party that uses the wrong termination mechanism may lose leverage, damages, or even the right to end the contract at all.
This guide explains the legal framework for termination of contracts under Turkish law in practical English. It covers the distinction between rescission and termination, termination for breach, notice termination, immediate termination for just cause, hardship, lease contracts, service agreements, consumer withdrawal rights, and the main legal consequences that follow when a contract comes to an end.
The Basic Distinction: Rescission Versus Termination
One of the most important concepts in Turkish contract law is that the end of a contract can take different legal forms. In reciprocal contracts, when one party falls into default and the statutory conditions are met, the other party may in some cases rescind the contract. Under Article 125 of the Turkish Code of Obligations, if the debtor does not perform within the additional period granted by the creditor, or where no additional period is required, the creditor may waive performance and delay damages and instead claim damages for non-performance or withdraw from the contract. The article also states that, upon rescission, the parties are released from their obligations to perform and may reclaim what they have already rendered.
By contrast, Turkish law uses termination more naturally for contracts involving continuing performance. Article 126 provides that in continuous-performance contracts where performance has already begun, the creditor may demand performance and delay damages, or may terminate the contract and seek compensation for the damage caused by the contract ending before its intended term. This is conceptually different from rescission. Rescission tends to unwind the exchange more strongly, while termination in continuing contracts usually ends the relationship for the future.
This distinction is not merely academic. In practical Turkish-law analysis, the lawyer must first ask whether the contract is a one-time exchange, such as a sale of specific goods, or a continuing relationship, such as a lease, service agreement, supply arrangement, subscription, or framework contract. The answer often determines whether the proper route is rescission, termination with notice, immediate termination, or a contract-specific statutory ending mechanism.
Termination by Expiry of the Agreed Term
Some contracts under Turkish law end automatically when the agreed term expires. The clearest example appears in the service-contract provisions of the Turkish Code of Obligations. Article 430 states that a fixed-term service contract ends automatically at the end of its term unless otherwise agreed. It also says that if the fixed-term contract continues tacitly after the end of the term, it becomes an indefinite-term contract. The same provision allows either party to terminate a service contract lasting more than ten years after the tenth year by complying with a six-month notice period.
A similar idea also appears in lease law. Article 327 states that if a lease is concluded for a fixed term, it ends automatically at the end of that term. However, if the parties continue the lease relationship without an express new agreement, the lease turns into an indefinite-term lease. This rule is highly important in practice because parties often assume that the end date alone resolves everything. Under Turkish law, actual continuation of the relationship can transform the legal nature of the contract.
The practical lesson is that expiry is not always the end of the story. In Turkish law, conduct after the end of the original term may produce a statutory continuation or conversion into an indefinite relationship, especially in lease and service settings. Businesses should therefore manage end-of-term conduct carefully if they wish to avoid unintended continuation.
Termination for Default in Reciprocal Contracts
One of the core routes for ending a contract under Turkish law is termination or rescission based on the other party’s default. Article 123 of the Turkish Code of Obligations provides that in reciprocal contracts, if one party falls into default, the other party may grant an appropriate additional period for performance or ask the court to grant one. Article 124 then lists cases where giving an additional period is unnecessary, such as where granting time would clearly be ineffective, where performance has become useless for the creditor because of the delay, or where the contract shows that late performance would no longer be accepted.
After that point, Article 125 gives the creditor its election of remedies. The creditor may still demand performance together with delay damages. Alternatively, the creditor may immediately declare that it waives performance and delay damages and instead claim damages arising from non-performance or rescind the contract. The same article states that, upon rescission, the parties are freed from reciprocal performance duties and may reclaim what they already performed; if the debtor cannot prove absence of fault in falling into default, the creditor may also seek damages caused by the contract becoming ineffective.
This is one of the most important termination frameworks in Turkish law because it shows that ending the contract is only one of several possible responses to breach. The creditor must make a strategic choice. Keeping the contract alive and forcing performance may be commercially better in some disputes, while rescission and damages may be preferable in others. Under Turkish law, the end of the contract is often a choice-based remedy rather than an automatic consequence.
Termination in Continuous-Performance Contracts
Article 126 of the Turkish Code of Obligations addresses continuous-performance contracts where performance has already started. It provides that where the debtor falls into default, the creditor may claim performance and delay damages, or may terminate the contract and demand compensation for the damage caused by the contract ending before its intended duration. This provision is especially relevant for long-term supply, maintenance, agency-like service structures, subscription agreements, framework arrangements, and other contracts whose commercial value lies in their continued existence over time.
This rule matters because the logic of a continuing contract is different from that of a one-off exchange. In a continuing relationship, the key issue is often not whether already rendered performance must be unwound, but whether the relationship can continue and, if not, what financial consequences follow from premature ending. Turkish law recognizes that distinction and gives the creditor a termination remedy that is tailored to ongoing contractual cooperation.
In practice, this means that termination clauses in Turkish-law long-term contracts should be drafted carefully, but they will also operate alongside the statutory regime. A contractual clause cannot safely be assessed in isolation from Article 126 and the broader rules on default, damages, and good faith.
Ordinary Termination by Notice in Indefinite-Term Contracts
Indefinite-term contracts under Turkish law are often terminable by notice, but the exact rules depend on the contract type. In the service-contract regime, Article 431 states that either party has the right to terminate an indefinite-term service contract by observing the notice periods. Article 432 then specifies the notice periods: two weeks where the service lasted up to one year, four weeks where it lasted from one to five years, and six weeks where it lasted more than five years. The article also states that these notice periods cannot be shortened, though they may be extended by contract, and that the employer may terminate by paying the wage corresponding to the notice period in advance.
Turkish lease law also contains general notice-based termination rules for indefinite leases. Article 328 provides that, unless a longer notice period or another termination period has been agreed, either party may terminate an indefinite-term lease according to the statutory termination periods. The same source shows that lease law further differentiates according to the nature of the leased asset and the specific category of lease.
Notice-based termination in Turkish law therefore depends on two questions. First, is the contract indefinite in duration, either originally or because it converted by continuation after expiry? Second, does the specific contract type carry its own statutory notice framework? A valid end-of-contract strategy must answer both questions before any notice is sent.
Immediate Termination for Just Cause
Not every contract must be carried through the ordinary notice process. Turkish law also recognizes immediate termination for just cause. In the service-contract regime, Article 435 states that either party may terminate the contract immediately for justified reasons and must notify the reason in writing. The article adds that all circumstances and conditions making it unreasonable, under the rules of honesty, to expect the terminating party to continue the service relationship qualify as just cause.
Article 437 regulates the consequences of such immediate termination. If the justified reason arose from one party’s non-compliance with the contract, that party must fully compensate the damage caused, taking into account all rights arising from the service relationship. In other situations, the court evaluates the material consequences of justified termination in light of all circumstances. Article 438 then addresses unjustified immediate termination by the employer and allows the worker to claim compensation equivalent to what would have been earned during the relevant notice period or, for fixed-term contracts, during the unexpired term, subject to deductions and possible judicial additional compensation.
The deeper principle here is not limited to service contracts. Turkish law generally allows extraordinary ending mechanisms where the continuation of the relationship has become intolerable or where one side’s conduct destroyed the basis of trust that made the contract viable. In practice, however, the exact form and consequences of immediate termination depend heavily on the statutory regime governing the specific contract.
Hardship and the Right to Seek Adaptation or Exit
Another important route toward ending or reshaping a contract under Turkish law appears in Article 138 of the Turkish Code of Obligations, which regulates excessive difficulty of performance. The article 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 and changes the factual basis of the contract to such an extent that demanding performance from the debtor would be contrary to the rules of good faith. The debtor must also not yet have performed, or must have performed while reserving rights arising from the excessive difficulty. In such a case, the debtor may request adaptation of the contract from the court and, if adaptation is not possible, may rescind the contract; in continuous-performance contracts, the debtor may use termination instead of rescission.
This provision is extremely important in modern Turkish contract practice because it creates a statutory link between hardship and contract ending. Turkish law does not automatically free a party from the contract merely because performance became more difficult or more expensive. But where the statutory threshold is met, the debtor may first seek judicial adaptation and then, if adaptation is not possible, move toward an end-of-contract remedy.
In practical terms, Article 138 often matters in long-term commercial contracts exposed to extraordinary market disruption, currency instability, regulatory shocks, or supply-chain breakdowns. But the threshold remains high. Ordinary commercial risk is not enough. The statute is built around exceptional change and good-faith imbalance, not routine inconvenience.
Lease Termination Under Turkish Law
Lease contracts are one of the most termination-sensitive contract types under Turkish law. The Turkish Code of Obligations contains a detailed lease-specific termination regime. For indefinite-term leases, Article 328 provides a general notice-based mechanism. Article 330 allows either party to terminate a movable lease at any time by complying with a three-day notice period, while also containing a specific rule for movables leased professionally to the tenant for private use. Article 331 then recognizes extraordinary termination for important reasons, allowing either party to terminate the lease at any time by observing the statutory notice period if important reasons make continuation unbearable. The judge decides the financial consequences by considering all circumstances.
Lease law also contains event-based ending mechanisms. Article 332 states that if the tenant becomes bankrupt after delivery of the leased property, the lessor may demand security for accruing rent; if security is not given within the written period granted, the lessor may terminate immediately without complying with any notice period. Article 333 allows the tenant’s heirs to terminate if the tenant dies, provided they observe the statutory notice framework.
These provisions show that Turkish law treats leases as highly structured continuing contracts. Termination is not governed solely by the general default and damages provisions. Lease-specific notice rules, extraordinary grounds, bankruptcy, death, and contract category all matter. Any legal assessment of lease termination in Turkey must therefore start with the lease chapter, not with abstract contract-law principles alone.
Residential and Roofed Workplace Leases: Stronger Tenant Protection
Residential and roofed workplace leases have an even more specific termination regime. Article 347 states that in fixed-term residential and roofed workplace leases, the lease is deemed extended for one year on the same conditions unless the tenant gives notice at least fifteen days before expiry. The same article states that the landlord cannot terminate merely by relying on the end of the term. However, after ten years of extension, the landlord may terminate without showing cause by giving notice at least three months before the end of each extension year. For indefinite-term residential and roofed workplace leases, the tenant may terminate at any time, while the landlord may do so only after ten years from the start of the lease, using the general notice mechanism.
Article 348 adds that termination notices in residential and roofed workplace leases are valid only if made in writing. Article 349 further protects the family home by stating that the tenant cannot terminate a lease over a family residence without the spouse’s explicit consent, unless that consent cannot be obtained or is unjustifiably withheld and a judge intervenes.
This is one of the clearest examples of Turkish law limiting ordinary contractual freedom in favor of social protection and housing stability. In these lease types, the landlord’s ability to end the contract is deliberately narrower than in ordinary indefinite contracts, while form and family-protection requirements become more stringent.
Service Contracts Under Turkish Law
Service contracts receive a structured termination framework in the Turkish Code of Obligations. As noted, Article 430 governs expiry of fixed-term service contracts, while Articles 431 and 432 regulate termination of indefinite-term service contracts by notice. Article 433 then permits termination without compensation during a probation period, provided the probation does not exceed two months. Article 434 provides protection against abusive termination and requires the employer to pay compensation equal to three times the notice-period wage where the termination right was abused.
The Code then adds immediate termination for just cause in Article 435 and special protection where the employer falls into insolvency in Article 436. Article 437 regulates the financial consequences of justified immediate termination, while Article 438 deals with unjustified immediate termination by the employer and Article 439 addresses the employee’s unjustified failure to start work or sudden departure.
This framework shows that service-contract termination in Turkey is not a single event but a complete legal regime. Fixed-term expiry, indefinite-term notice, probation, abuse of termination rights, just cause, insolvency, and compensation all interact. Any business using Turkish-law service agreements outside the Labour Law context should assess termination risk article by article rather than by relying on broad assumptions imported from foreign jurisdictions.
Consumer Contracts and Statutory Withdrawal Rights
Consumer law introduces another important way in which contracts may end under Turkish law: the right of withdrawal. Article 48 of the Law on the Protection of Consumers defines distance contracts and requires the seller or supplier to inform the consumer clearly before the contract is concluded. It also provides that the consumer may withdraw from the distance contract within fourteen days without giving reasons and without penalty, and states that if the consumer was not properly informed of the withdrawal right, the consumer is not bound by the ordinary fourteen-day limit and the period can extend up to one year after expiry of the normal withdrawal period.
For distance contracts concerning financial services, Article 49 creates a similar fourteen-day withdrawal right and adds an important termination principle: the consumer may communicate the request to terminate the contract through a distance communication method, and the consumer cannot be forced to use a termination method that is more burdensome than the method used to conclude the contract. The Regulation on Distance Contracts for Financial Services reinforces this approach and states that it is sufficient for the consumer to provide the demand for termination by any remote communication means; it also requires record retention for three years.
These rules matter because they show that under Turkish consumer law, ending the contract may take place through statutory withdrawal rather than breach-based rescission or ordinary notice termination. Consumer-facing businesses should therefore treat withdrawal compliance, communication channels, and recordkeeping as part of their termination-risk framework, not merely as post-sale customer-service issues.
Consequences of Termination Under Turkish Law
The legal consequences of ending a contract depend on the path used. Under Article 125, where a reciprocal contract is rescinded because of default, the parties are released from future performance obligations and may reclaim what they already rendered. The creditor may also recover damages caused by the contract becoming ineffective if the debtor cannot prove absence of fault in falling into default. In continuing contracts terminated under Article 126, the consequence is more prospective: the relationship ends, and the creditor may seek compensation for the loss caused by premature ending.
In hardship cases under Article 138, the court-centered structure means adaptation comes first in principle, and only where adaptation is not possible does rescission or termination enter the picture. In lease and service contracts, the Code often adds notice rules, form requirements, or contract-specific financial consequences. In consumer law, ancillary obligations may also be affected by withdrawal, and businesses may face duties of refund, disclosure, and record production.
This is why “termination” should never be treated as a uniform label in Turkish law. The correct legal consequence depends on the statutory route used to end the contract. The party ending the contract must therefore identify the correct mechanism before assuming anything about restitution, survival clauses, accrued rights, or damages.
Procedural Issues: Mediation and Dispute Resolution
Termination disputes often evolve into monetary claims, damages claims, restitution claims, or declaratory actions. In commercial matters, Article 5/A of the Turkish Commercial Code provides that in commercial disputes concerning monetary receivables, compensation, annulment of objection, negative declaratory actions, and restitution, applying to a mediator before filing suit is a condition of action. The same article states that the mediator normally completes the process within six weeks, extendable by up to two weeks in compulsory cases.
The general Mediation Law also states that it applies to private-law disputes over matters on which the parties may freely dispose, including disputes with a foreign element, while excluding disputes involving allegations of domestic violence. That means many contract-termination disputes are, in principle, mediable, and some commercial ones are mandatorily so before litigation.
This procedural layer matters because a party may correctly terminate the contract under substantive Turkish law and still make a procedural mistake when enforcing the consequences. In cross-border and business disputes, the termination analysis should therefore include not only the statutory basis for ending the contract but also the correct pre-litigation route.
Practical Drafting Lessons
A well-drafted Turkish-law contract should distinguish clearly between expiry, termination with notice, immediate termination for just cause, default-based rescission, and termination of continuing performance. These are not interchangeable concepts under Turkish law. A contract that uses one general English word such as “termination” for all situations may create confusion when the dispute reaches a Turkish court or arbitral tribunal.
It is also wise to regulate notice mechanics carefully. Where the statute requires written notice, such as residential and roofed workplace lease termination under Article 348, failure to comply can undermine the attempted ending of the contract. In other contexts, clear due dates and cure periods can determine whether additional notice is needed before the termination route opens.
Finally, parties should remember that Turkish law often overlays contract-specific rules onto general termination principles. Lease, service, consumer, and commercial disputes each carry additional statutory considerations. A contract-ending strategy that is sound in one area may be defective in another.
Conclusion
Termination of contracts under Turkish law is a structured subject rather than a single doctrine. The Turkish Code of Obligations distinguishes between rescission in reciprocal contracts, termination of continuous-performance relationships, notice-based ending of indefinite contracts, immediate termination for just cause, expiry of fixed terms, and adaptation-or-exit in hardship situations. Lease law and service-contract law each contain detailed special regimes, while consumer law adds withdrawal rights and termination-friendly communication protections in distance contracts.
The practical lesson is simple: before ending a contract in Turkey, the party should identify the contract type, determine whether the relationship is fixed-term or indefinite, decide whether the issue is default, hardship, just cause, or ordinary notice, and verify the statutory consequences of the chosen route. In Turkish law, the difference between rescission, termination, and withdrawal is not semantic. It shapes restitution, damages, notice, form, and procedure.
A party that classifies the ending mechanism correctly usually stands in a much stronger legal position. A party that treats all exits as the same “termination” risks using the wrong statutory path and weakening its own case from the start.
FAQ
What is the difference between rescission and termination under Turkish law?
In Turkish law, rescission is typically associated with reciprocal contracts after default under Article 125, while termination is more natural for continuing-performance contracts under Article 126 and for contract-specific notice or just-cause ending mechanisms.
Can a fixed-term contract simply end by itself?
Yes, in some contract types. For example, Article 430 states that a fixed-term service contract ends automatically at the end of its term unless otherwise agreed, and Article 327 similarly provides that a fixed-term lease ends automatically at term end.
Is notice always required before terminating a contract in Turkey?
No. In some cases notice is required, such as indefinite-term service contracts under Articles 431 and 432 or certain lease terminations. In default-based rescission, an additional period may be required under Article 123 unless Article 124 makes it unnecessary. In just-cause termination, immediate ending may be possible.
Can a contract be ended because performance became excessively difficult?
Yes. Article 138 allows the disadvantaged party to seek judicial adaptation where extraordinary and unforeseeable circumstances made performance excessively burdensome; if adaptation is not possible, the party may rescind, or terminate in continuing-performance contracts.
Are residential leases easy for landlords to terminate in Turkey?
No. Article 347 gives strong protection to tenants in residential and roofed workplace leases, including automatic extension in many fixed-term cases and restricted landlord termination rights. Article 348 also requires written termination notice.
Can consumers end distance contracts easily in Turkey?
Consumers generally have a fourteen-day withdrawal right in distance contracts under Article 48, and in distance financial-services contracts Article 49 says they cannot be forced to use a termination method more burdensome than the one used to establish the contract.
