How Can You Enforce a Contract in Turkey? Formal Notice, Injunctions, Damages & Enforcing Judgments (2026)

When a commercial counterparty in Turkey fails to perform, the first question every creditor asks is straightforward: how can you enforce a contract and what are the fastest routes to a practical remedy? Turkish law provides a well-defined enforcement framework anchored in the Turkish Code of Obligations (Law No. 6098), the Civil Procedure Code (HMK, Law No. 6100), and the Execution and Bankruptcy Law (İcra ve İflas Kanunu), supplemented by the Act on Private International Law (MÖHUK, Law No. 5718) for cross-border matters.

This guide walks in-house counsel, international creditors and business managers through every actionable step, from preserving evidence and issuing a formal notice of default, through obtaining interim injunctions and court judgments, to executing those judgments against the defaulting party’s assets in Turkey. For commercial law disputes with a Turkish element, understanding these procedural steps is the difference between a paper right and an enforceable outcome.

TL;DR, How Can You Enforce a Contract in Turkey? Quick Roadmap

Turkish contract enforcement follows a logical sequence. Whether the breach involves non-payment, late delivery or defective performance, the core roadmap is the same. The key variable is speed: urgent cases may justify interim injunctive relief before the main suit is even filed, while straightforward debt claims can proceed directly through execution proceedings.

For cross-border creditors holding a foreign court judgment or arbitral award, an additional recognition step under MÖHUK (Law No. 5718) is required before Turkish enforcement mechanisms become available. Industry observers expect this recognition process to take between 6 and 18 months in practice, depending on court workload and whether the debtor raises defences.

Five-step enforcement roadmap:

1. Preserve evidence and secure your contract. Gather the signed agreement, invoices, delivery records, correspondence and any proof of the breach.
2. Issue a formal notice of default. Serve a written notice via notary public setting out the breach and a reasonable cure period.
3. Seek interim injunctions if harm is urgent. Apply to the competent court for precautionary measures or preliminary attachment of assets under the HMK.
4. File a substantive claim or commence enforcement. Initiate a lawsuit, arbitration or, for undisputed monetary debts, direct execution proceedings.
5. Execute the judgment. Use the İcra (Execution) system for seizure, garnishment and auction of assets, or seek recognition of a foreign judgment first if the award originates abroad.

Step 1, Immediate Practical Steps When a Counterparty Defaults

Gather and preserve evidence

Before taking any formal legal step, the priority is to build an evidence file that will withstand scrutiny in Turkish courts. Turkish civil litigation follows the principle that each party bears the burden of proving the facts it relies upon. Incomplete documentation is the single most common reason commercial claims under-perform.

Evidence preservation checklist:

• Contract and annexes. Secure the original signed copy, all amendments and side letters.
• Communications. Export and archive emails, messaging threads and meeting minutes that demonstrate the counterparty’s obligations and admissions.
• Performance records. Collect invoices, delivery receipts, inspection reports, payment confirmations and bank transfer records.
• Breach documentation. Photograph defective goods, record missed delivery dates, note unfulfilled milestones with timestamps.
• Prior notices. Retain copies of any verbal or written complaints already sent, these may count as informal notice of default under certain conditions.

Commercial vs consumer cases, different rules apply

Turkish law distinguishes sharply between commercial and consumer contracts. Commercial disputes between merchants are heard by specialised Commercial Courts of First Instance, while consumer disputes follow a separate procedural track under the Consumer Protection Law (Law No. 6502). The distinction affects jurisdiction, limitation periods, applicable interest rates and mandatory mediation requirements. The guidance in this article addresses commercial (B2B) contract enforcement. Consumer-facing businesses should seek specific advice on the consumer regime.

Formal Notice of Default in Turkey, What It Is, Why It Matters and a Practical Template

A formal notice of default (ihtar or ihtarname) is the cornerstone of almost every breach-of-contract claim in Turkey. Under the Turkish Code of Obligations (Law No. 6098), a debtor whose obligation has no fixed due date is not considered in default until the creditor serves a proper notice demanding performance. Even where a specific due date exists, issuing a formal notice strengthens the creditor’s position, triggers the obligation to pay default interest, and satisfies pre-litigation requirements.

The notice should be prepared and served through a Turkish notary public (noter) to create an official, timestamped record with evidentiary weight. Notary-served notices are presumed to have been delivered on the date of service, which eliminates disputes about whether the debtor was properly informed.

Key elements of an effective notice of default

When to skip the cure period and litigate immediately

Certain circumstances justify bypassing the cure period entirely. Where the contract sets a fixed performance date that has passed, a shipment due on a specific calendar date, for example, default arises automatically without notice under the time-fixed obligation rules. Similarly, if the debtor has expressly declared that it will not perform, or if performance has become impossible, the creditor may proceed directly to litigation or termination. In practice, even in these cases, a formal notice recording the breach is advisable because it strengthens the documentary record and forecloses procedural objections.

Interim Relief and Injunctions in Turkey, How to Stop Harm Fast

When the breach threatens irreparable harm, asset dissipation, ongoing IP infringement, or destruction of goods, waiting for a full trial is not practical. Turkish law offers several forms of interim relief under the HMK (Law No. 6100) that allow courts to intervene quickly.

Types of interim measures available

• Precautionary injunctions (ihtiyati tedbir). Courts may order a party to do or refrain from doing something to preserve the status quo pending final judgment. Common examples include freezing bank accounts, prohibiting the disposal of disputed property, or ordering continued supply of essential goods.
• Preliminary attachment (ihtiyati haciz). This is the Turkish equivalent of a pre-judgment freezing order over the debtor’s assets. It is available under the Execution and Bankruptcy Law where the creditor demonstrates a risk that the debtor will hide or dissipate assets. Preliminary attachment creates a lien that converts into a definitive seizure once judgment is obtained.
• Interim measures pending arbitration. Where the contract contains an arbitration clause, Turkish courts retain jurisdiction to grant interim relief in support of the arbitral process. The arbitral tribunal may also order interim measures once constituted.

Procedure and evidence standard

Applications for interim injunctions in Turkey are typically heard on an expedited basis. The applicant must demonstrate: (1) a prima facie claim on the merits; (2) urgency, a risk of irreparable harm or that enforcement of the eventual judgment will be frustrated; and (3) proportionality, that the injunction does not impose disproportionate harm on the respondent. The court will ordinarily require the applicant to post a security bond (typically 15% of the claim value, though this varies by court) to cover potential damages if the injunction is later found to have been unjustified.

Urgent injunction checklist:

1. Petition setting out the factual basis, the legal right at risk and the specific measure sought.
2. Supporting evidence (contracts, correspondence, expert reports, photographs).
3. Explanation of urgency and irreparable harm.
4. Security bond (bank guarantee or cash deposit).
5. Power of attorney for Turkish counsel (notarised and, if issued abroad, apostilled).

Early indications suggest that Turkish courts typically hear urgent injunction applications within days of filing, with written decisions following shortly thereafter. If the application is granted ex parte, the respondent has the right to object, and a hearing with both parties will be scheduled promptly.

Main Remedies for Breach of Contract in Turkey, Damages, Specific Performance and Termination

Once default is established, Turkish law under the Code of Obligations (Law No. 6098) provides three primary categories of remedy. Understanding each is essential for choosing the right enforcement strategy.

Damages for breach, compensatory, interest and mitigation

The default remedy in Turkish commercial disputes is compensatory damages designed to put the injured party in the position it would have occupied had the contract been performed. Damages for breach in Turkey encompass direct loss (actual damage) and lost profit, provided the loss is proven with reasonable certainty and a causal link to the breach is established.

Default interest runs automatically from the date of default. For commercial transactions between merchants, the applicable rate is the commercial default interest rate published by the Central Bank of Turkey, which is typically significantly higher than the statutory civil rate. This distinction makes timely notice of default financially important.

Worked example, calculating damages:

• Contract price for undelivered goods: TRY 5,000,000
• Cost of substitute purchase from alternative supplier: TRY 6,200,000
• Compensatory damages claim: TRY 1,200,000 (difference) + commercial default interest from the date of default + any consequential losses (e.g., lost customer contracts) supported by evidence.

The injured party has a duty to mitigate. Turkish courts will reduce the damages award if the creditor failed to take reasonable steps to limit its loss, for instance, by unreasonably delaying a substitute purchase.

Specific performance, when courts compel performance

Turkish law recognises specific performance as a remedy, and courts may order a defaulting party to fulfil its contractual obligations rather than simply pay damages. However, specific performance is subject to practical limitations. Courts will not order performance where it has become objectively impossible, where it would amount to compelling personal services in a manner inconsistent with personal freedom, or where damages would adequately compensate the injured party. In practice, specific performance is most commonly ordered for obligations involving the transfer of unique property (such as real estate) or the delivery of specific, non-fungible goods.

Contract termination and rescission

Where the breach is material, the injured party may terminate the contract by giving notice (after the cure period expires, if applicable) and claim damages for the loss caused by the termination. Termination releases both parties from future performance obligations but preserves the right to claim damages for the breach that triggered termination. Turkish courts examine whether the breach is sufficiently serious to justify termination, a minor or peripheral failure will not support rescission if the overall contractual purpose can still be achieved.

How to Obtain and Enforce a Domestic Judgment, Enforcing Judgments in Turkey

Starting the lawsuit, competent courts and jurisdiction

Commercial contract claims are filed before the Commercial Courts of First Instance (Asliye Ticaret Mahkemesi). Jurisdiction is determined by a combination of the defendant’s domicile, the place of performance of the contract, and any jurisdiction clause in the agreement. Mandatory mediation now applies to most commercial disputes, the parties must attend a mediation session before filing suit, and the mediation certificate must be submitted with the statement of claim.

Obtaining judgment

First-instance proceedings in commercial courts typically involve written submissions, documentary evidence, witness examination and, where necessary, expert reports (particularly for quantum of damages). The likely practical effect is that straightforward debt claims may resolve in 6 to 12 months, while complex commercial disputes can take 12 to 18 months at first instance, with appeal adding further time.

Enforcement via İcra (Execution)

Once a final and enforceable judgment is in hand, the creditor applies to the İcra (Execution) Office to commence enforcement proceedings under the Execution and Bankruptcy Law (İcra ve İflas Kanunu). The execution system provides powerful tools for enforcing judgments in Turkey:

• Seizure of assets (haciz). The execution office can seize the debtor’s movable and immovable property, bank accounts, vehicles and receivables.
• Garnishment. Third parties owing money to the debtor (customers, banks) can be ordered to pay directly to the creditor.
• Auction (satış). Seized assets are sold at public auction, with proceeds distributed to the creditor.
• Bankruptcy petition. If the debtor is a merchant and cannot satisfy its debts, the creditor may petition for bankruptcy proceedings, which create a collective enforcement regime.

Execution fees are calculated as a percentage of the claim amount and are ultimately borne by the debtor if enforcement is successful.

Enforcing Foreign Judgments and Arbitral Awards in Turkey (2026 Practice Notes)

International creditors holding a judgment from a foreign court or an arbitral award face an additional procedural layer: recognition and enforcement under Turkish law. The applicable framework depends on whether the source is a court judgment or an arbitral award, and whether a bilateral or multilateral treaty applies.

Recognition versus enforcement under MÖHUK (Law No. 5718)

For foreign court judgments, the primary statute is the Act on Private International Law and International Civil Procedure (MÖHUK, Law No. 5718). To enforce a foreign judgment in Turkey, the creditor must bring a separate recognition and enforcement action before the competent Turkish court. The court will examine whether the following conditions are met:

1. Reciprocity. There must be a reciprocal arrangement (by treaty or de facto practice) between Turkey and the country of origin regarding the mutual enforcement of judgments.
2. Finality. The judgment must be final and enforceable under the law of the country of origin.
3. Jurisdiction. The foreign court must have had jurisdiction over the dispute under Turkish private international law principles.
4. Due process. The defendant must have been properly served and had the opportunity to present a defence.
5. Public policy. The judgment must not be manifestly contrary to Turkish public order.

The Turkish court does not review the merits of the underlying dispute. It conducts a limited procedural review based on the conditions above.

Common defences and practical timeline

Debtors resisting enforcement typically raise public policy objections, challenge reciprocity (particularly for judgments from jurisdictions without a bilateral enforcement treaty with Turkey), or argue improper service. The reciprocity requirement remains the most contested issue in practice, though Turkish courts have adopted a relatively liberal interpretation, accepting de facto reciprocity based on demonstrated practice in the originating jurisdiction.

Documentary requirements for the enforcement petition:

• Certified copy of the foreign judgment with a finality certificate.
• Certified Turkish translation of all documents (by a sworn translator).
• Apostille or consular legalisation (depending on whether the originating country is party to the Hague Apostille Convention).
• Power of attorney for Turkish counsel.

For foreign arbitral awards, Turkey is a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958). Enforcement follows a simplified procedure, and the grounds for refusal are narrower than those for court judgments. Once recognised, a foreign arbitral award is enforceable through the İcra system in the same manner as a domestic judgment.

Costs, Timelines and Tactical Decision Tree, Settle, Arbitrate or Litigate?

Choosing the right enforcement route is a strategic decision that depends on the claim value, the debtor’s asset base in Turkey, and the origin of the underlying judgment or contract. The comparison below provides a practical framework.

Tactical considerations: Where the contract includes an ICC or LCIA arbitration clause, the resulting award benefits from the streamlined New York Convention enforcement route, which is generally faster and more predictable than foreign-judgment recognition. For purely domestic disputes, direct litigation in Turkish Commercial Courts provides the fastest path to the İcra system. Settlement should always be evaluated early, mandatory mediation creates a structured opportunity, and early settlement avoids the full cost of litigation while preserving business relationships.

Practical Templates and Checklists for Enforcing a Contract in Turkey

Template: Formal notice of default

The following template should be adapted to the specific facts and served via notary public:

[Notary header]
To: [Debtor name, address]
From: [Creditor name, address]
Date: [Date]
Re: Notice of Default, [Contract title and date]

We refer to the [Contract title] entered into between [Creditor] and [Debtor] on [date] (the “Agreement”). Under the Agreement, you are obligated to [describe the obligation, e.g., deliver goods / make payment / complete services] by [due date or upon demand].

As of the date of this notice, you have failed to [describe the breach]. This constitutes a breach of your obligations under the Agreement.

We hereby demand that you cure the above breach within [30/60] days of receipt of this notice by [describe required cure action]. If you fail to do so, we reserve all rights under the Agreement and applicable law, including the right to terminate the Agreement, claim compensatory damages, default interest and costs, and commence enforcement proceedings.

Conclusion, Enforce a Contract in Turkey With Confidence

Understanding how can you enforce a contract under Turkish law means mastering a clear procedural sequence: preserve evidence, issue a formal notice of default, seek interim protection where urgency demands it, pursue substantive remedies through litigation or arbitration, and execute the resulting judgment through Turkey’s İcra system. For cross-border disputes, the recognition framework under MÖHUK and the New York Convention provides defined pathways for foreign judgments and arbitral awards. The key to effective enforcement is early action, thorough documentation and experienced local counsel who can navigate both the procedural requirements and the practical realities of Turkish commercial courts. For expert guidance on commercial contract disputes in Turkey, connecting with a qualified practitioner is the essential first step.
