Litigation & Arbitration in Turkey: Frequently Asked Questions

Turkey sits at the intersection of European and Asian commercial networks, making it one of the most active jurisdictions for cross-border disputes. When a contract breaks down, a joint venture collapses, or a debt goes unpaid, foreign businesses face an immediate strategic question: pursue litigation in Turkish state courts, opt for arbitration, or seek enforcement of a foreign award? Each path carries distinct procedural requirements, timelines, and cost structures that differ substantially from Western European or common-law systems.

This article answers the most frequently asked questions about litigation and arbitration in Turkey. It covers the structure of Turkish courts, the arbitration framework, procedural timelines, enforcement of foreign judgments and awards, pre-trial steps, and the practical risks that international clients consistently underestimate. The goal is to give decision-makers a clear map before committing resources to a dispute strategy.

Turkey operates a unified civil judiciary under the Code of Civil Procedure (Hukuk Muhakemeleri Kanunu, Law No. 6100, hereinafter HMK). Commercial disputes are handled by specialised Commercial Courts of First Instance (Asliye Ticaret Mahkemesi), which sit in every major city. Istanbul alone has multiple chambers, each assigned by subject matter. Appeals go to the Regional Courts of Appeal (Bölge Adliye Mahkemesi), introduced as an intermediate appellate tier, and final review lies with the Court of Cassation (Yargıtay).

The Commercial Courts have exclusive jurisdiction over disputes between merchants, corporate matters, and claims arising from commercial transactions as defined by the Turkish Commercial Code (Türk Ticaret Kanunu, Law No. 6102, hereinafter TTK). A foreign company that has signed a contract with a Turkish counterpart and designated Turkish courts as the forum will litigate before these chambers. Subject-matter jurisdiction is determined by the nature of the claim; monetary thresholds affect whether a case goes to a Civil Court of Peace (Sulh Hukuk Mahkemesi) or a full Commercial Court.

Enforcement courts (İcra Mahkemesi) handle objections to enforcement proceedings and are procedurally separate from the merits courts. This distinction matters practically: a creditor can initiate enforcement of a monetary claim through the bailiff system (icra takibi) without first obtaining a court judgment, but the debtor can object, triggering a separate enforcement court proceeding. Understanding which court handles which step prevents costly procedural errors at the outset.

In practice, it is important to consider that Istanbul courts, while the most commercially sophisticated, carry heavy caseloads. First-instance proceedings in complex commercial disputes routinely take 18 to 36 months. Appeals add another 12 to 24 months at the regional level, and Yargıtay review can extend the timeline further. A common mistake made by international clients is to assume that Turkish litigation timelines resemble those of arbitration or of courts in smaller jurisdictions.

Arbitration in Turkey is governed by two parallel frameworks. Domestic arbitration follows Part 4 of the HMK (Articles 407-444). International arbitration - defined by the International Arbitration Law (Milletlerarası Tahkim Kanunu, Law No. 4686, hereinafter MTK) - applies when at least one party is domiciled or habitually resident abroad, or when the subject matter of the dispute has a foreign element. The MTK is modelled on the UNCITRAL Model Law, which makes it broadly familiar to international practitioners.

The Istanbul Arbitration Centre (Istanbul Tahkim Merkezi, ISTAC) is Turkey';s primary institutional arbitration body. Established under Law No. 6570, ISTAC administers both domestic and international cases under its own rules. Parties may also choose the ICC, LCIA, VIAC, or any other institution; Turkish law does not restrict the choice of arbitral institution for international disputes. Ad hoc arbitration under UNCITRAL Rules is equally valid.

Arbitration agreements in Turkey must be in writing, as required by Article 4 of the MTK. An arbitration clause embedded in a main contract satisfies this requirement. Turkish courts treat arbitration clauses as separable from the underlying contract, meaning a dispute about contract validity does not automatically void the arbitration clause. This separability principle, codified in Article 7 of the MTK, is frequently litigated when a party attempts to escape arbitration by challenging the main contract.

A non-obvious risk is the interaction between Turkish mandatory law and arbitral jurisdiction. Certain disputes - including some employment matters, consumer claims, and disputes over immovable property located in Turkey - cannot be referred to arbitration under Turkish law. Submitting such a dispute to arbitration produces an award that Turkish courts will refuse to enforce. Identifying these exclusions before drafting the dispute resolution clause is essential.

Seat of arbitration matters significantly. If the seat is in Turkey, the MTK governs procedural challenges and annulment. If the seat is abroad, the resulting award is a foreign award subject to recognition and enforcement under the New York Convention, to which Turkey is a signatory. Many international parties choose a neutral seat - Vienna, Geneva, or Singapore - while designating Turkish law as the governing substantive law. This combination is enforceable and widely used in Turkish practice.

Turkish civil procedure requires no formal pre-litigation demand as a universal rule, but several specific regimes impose mandatory pre-trial steps. Consumer disputes must go through a mandatory mediation process before any court filing. Commercial disputes between merchants have been subject to mandatory mediation (zorunlu arabuluculuk) since the amendment to the Commercial Code under Law No. 7155, which added Article 5/A to the TTK. This step is a procedural prerequisite: a court will dismiss a commercial monetary claim filed without first attempting mediation.

Mediation under the Turkish Mediation in Civil Disputes Law (Hukuki Uyuşmazlıklarda Arabuluculuk Kanunu, Law No. 6325) is conducted by a registered mediator. The parties must attend at least one session. If mediation fails, the mediator issues a non-agreement record (anlaşamama tutanağı), which the claimant attaches to the court filing. The mediation phase typically takes three to eight weeks, depending on party cooperation and mediator availability.

Interim measures are available both in litigation and in arbitration. Turkish courts can grant precautionary attachment (ihtiyati haciz) over assets and precautionary injunctions (ihtiyati tedbir) under Articles 389-406 of the HMK. A claimant seeking precautionary attachment of a monetary claim must demonstrate a credible claim and a risk that enforcement will be frustrated. Courts typically require security from the applicant, usually set at a fraction of the claimed amount, to compensate the respondent if the measure proves unjustified.

In arbitration, the arbitral tribunal seated in Turkey has authority to order interim measures under Article 6 of the MTK. However, parties frequently apply to state courts for interim measures before the tribunal is constituted, which is expressly permitted. A common mistake is waiting for the tribunal to be formed before seeking asset freezes - by that point, assets may have been dissipated. Acting within the first days of a dispute, before the counterparty is aware of the claim, is often decisive.

Electronic filing (UYAP - National Judiciary Informatics System) is mandatory for lawyers in Turkish courts. All submissions, evidence, and procedural documents are filed through the UYAP portal. Foreign parties represented by Turkish counsel will interact with this system through their lawyer. Direct access for foreign parties without Turkish bar-registered representation is not available, making the choice of local counsel a threshold operational decision.

Turkey enforces foreign court judgments through a recognition and enforcement (tanıma ve tenfiz) procedure governed by the Private International Law and Procedural Law (Milletlerarası Özel Hukuk ve Usul Hukuku Hakkında Kanun, Law No. 5718, hereinafter MÖHUK). A foreign judgment does not automatically become enforceable in Turkey. The creditor must file a separate action before a Turkish court of first instance, which reviews the judgment against the conditions set out in Articles 50-59 of MÖHUK.

The key conditions for enforcement of a foreign judgment are:

• The foreign court must have had jurisdiction under Turkish conflict-of-laws rules.
• The judgment must be final and binding in the country of origin.
• The judgment must not violate Turkish public policy (kamu düzeni).
• The defendant must have been duly served and given the opportunity to defend.
• There must be reciprocity between Turkey and the country of origin, either by treaty or de facto practice.

The reciprocity requirement is the most frequently contested condition. Turkey has bilateral enforcement treaties with a limited number of states. For countries without a treaty, Turkish courts assess whether the foreign state enforces Turkish judgments in practice. Courts in Istanbul have developed a relatively pragmatic approach to reciprocity for major trading partners, but the outcome is not guaranteed. This uncertainty is one reason why arbitration - which bypasses the reciprocity issue - is often preferred for international contracts.

Foreign arbitral awards are enforced under the New York Convention (1958), to which Turkey acceded with the commercial reservation. This means Turkey applies the Convention only to disputes considered commercial under Turkish law. The enforcement procedure follows Articles 60-62 of MÖHUK and mirrors the Convention';s grounds for refusal. Turkish courts have generally been receptive to enforcing New York Convention awards, though public policy objections are raised with some frequency and occasionally succeed where the award conflicts with mandatory Turkish law provisions.

The enforcement timeline for a foreign award or judgment, from filing to obtaining an enforcement order, typically ranges from six to eighteen months at first instance, depending on whether the respondent contests the proceedings. Uncontested enforcement can be faster. Legal costs for enforcement proceedings start from the low thousands of EUR, with higher fees for complex or high-value matters.

Scenario one: a mid-size distribution dispute. A European supplier has a contract with a Turkish distributor for EUR 800,000 in unpaid invoices. The contract contains no dispute resolution clause. The supplier';s options are Turkish state courts or, if the parties agree post-dispute, arbitration. Without an arbitration agreement, the supplier must litigate. Filing in Istanbul Commercial Court, completing mandatory mediation, and proceeding to judgment will take approximately two to three years at first instance. The supplier should simultaneously consider initiating enforcement proceedings (icra takibi) against the distributor';s known Turkish assets, which can proceed in parallel with the merits case and may produce faster practical results if the debt is undisputed.

Scenario two: a joint venture breakdown. Two shareholders - one Turkish, one foreign - disagree over the management and profit distribution of a Turkish limited liability company (limited şirket). The shareholders'; agreement contains an ISTAC arbitration clause with Istanbul as the seat. The foreign shareholder can file for arbitration, seek interim measures from Istanbul courts to prevent asset stripping, and pursue the merits before the tribunal. ISTAC proceedings for a dispute of this complexity typically take 12 to 24 months to award. The corporate law aspects - such as dissolution or compulsory share transfer - may require parallel proceedings before Turkish courts, since certain corporate remedies fall outside arbitral jurisdiction.

Scenario three: a construction contract claim. A foreign contractor has performed work in Turkey and is owed USD 3 million by a Turkish state-owned enterprise. The contract designates ICC arbitration with a seat in Paris and Turkish law as the governing law. The contractor can proceed to ICC arbitration, obtain an award, and then enforce it in Turkey under the New York Convention. The public policy defence is a realistic risk here because the respondent is a state entity and the claim involves public procurement. Structuring the claim to avoid reliance on grounds that Turkish courts might characterise as contrary to public policy is a strategic priority from the outset.

A loss caused by an incorrect strategy in scenario three - for example, filing in Turkish courts instead of pursuing ICC arbitration as contractually agreed - could result in the Turkish court declining jurisdiction and the claimant losing months of procedural time and incurring costs that do not advance the merits. Identifying the correct forum before the first filing is not a formality; it is a substantive strategic decision.

The economics of Turkish dispute resolution vary significantly by forum and claim size. State court litigation involves court filing fees (harç) calculated as a percentage of the claim value under the Fees Law (Harçlar Kanunu, Law No. 492). These fees are payable at filing and are recoverable from the losing party if the claimant succeeds. Lawyers'; fees for commercial litigation in Turkish courts start from the low thousands of EUR for straightforward claims and scale upward with complexity and claim value. The Turkish Bar Association publishes minimum fee tariffs, but market rates for international commercial work are typically higher.

Arbitration costs have a different structure. Institutional arbitration under ISTAC or ICC involves administrative fees and arbitrator fees, both of which scale with the amount in dispute. For a claim in the range of USD 1-5 million, total arbitration costs - administrative fees plus three arbitrators'; fees - can reach the mid-five-figure range in EUR or USD. Ad hoc arbitration reduces administrative costs but increases coordination burden. The cost of non-specialist mistakes - for example, selecting an arbitrator without Turkish law expertise for a Turkish-law-governed dispute - can manifest as a poorly reasoned award that is more vulnerable to annulment challenges.

Procedural burden in Turkish litigation is substantial. The HMK requires parties to submit all evidence with the initial pleadings (dilekçeler aşaması). Evidence submitted late is generally inadmissible unless the party demonstrates it could not have been obtained earlier. This front-loading requirement means that international clients must invest heavily in document collection and legal analysis before filing, not after. Many underappreciate this requirement and arrive at the filing stage with incomplete evidence, weakening their position from the start.

Expert witnesses (bilirkişi) play a central role in Turkish commercial litigation. Courts routinely appoint court-designated experts to assess technical, accounting, or valuation questions. The expert';s report carries significant weight, and challenging it requires a formal objection and, often, a counter-expert opinion. Budgeting for expert costs - which vary widely by subject matter - is a necessary part of dispute economics planning.

When comparing litigation and arbitration purely on cost, arbitration is not always cheaper. For smaller claims below EUR 200,000, Turkish court litigation may be more cost-effective, particularly if the debtor has identifiable assets in Turkey that can be attached quickly. For larger, complex, or cross-border disputes where confidentiality, enforceability across multiple jurisdictions, or neutrality of decision-makers matters, arbitration typically offers better value despite higher upfront costs.

A common mistake is treating Turkey as a single homogeneous legal environment. Istanbul, Ankara, and Izmir courts develop their own interpretive tendencies on contested legal questions, and the choice of venue within Turkey can affect outcomes on procedural and substantive issues. Venue rules under the HMK are not always straightforward for foreign parties, and filing in the wrong court results in a jurisdiction objection that delays proceedings by months.

Many underappreciate the role of Turkish procedural formalism. Documents submitted to Turkish courts must be in Turkish or accompanied by a certified translation. Apostilled foreign documents require translation by a sworn translator (yeminli tercüman). Failure to provide properly certified translations results in the document being disregarded. This requirement applies to corporate documents, contracts, correspondence, and foreign judgments alike. The cost and time of translation and certification should be built into the pre-litigation timeline.

A non-obvious risk is the statute of limitations (zamanaşımı). The general limitation period under the Turkish Code of Obligations (Türk Borçlar Kanunu, Law No. 6098, Article 146) is ten years for contractual claims, but specific commercial claims carry shorter periods - two years for certain commercial paper claims, five years for some agency and distribution claims. International clients sometimes apply the limitation period of their home jurisdiction and discover too late that the Turkish period has expired. Checking the applicable Turkish limitation period before deciding whether to act is a threshold step that cannot be deferred.

The risk of inaction is concrete: once a limitation period expires, the claim is permanently barred regardless of its merits. For a creditor with a EUR 500,000 claim approaching the limitation deadline, the cost of inaction - losing the claim entirely - dwarfs the cost of filing a protective action or initiating mediation to interrupt the period.

De jure, Turkish law provides robust procedural rights to foreign parties. De facto, navigating the UYAP electronic filing system, meeting translation requirements, complying with mandatory mediation, and managing the front-loading of evidence all require experienced local counsel from day one. Engaging Turkish lawyers only after a procedural problem has arisen is a pattern that consistently produces avoidable losses.

What is the biggest practical risk when litigating against a Turkish company in Turkish courts?

The most significant practical risk is asset dissipation before a judgment is obtained. Turkish litigation timelines at first instance are measured in years, and a counterparty aware of an impending claim can transfer or encumber assets during that period. The correct response is to apply for precautionary attachment (ihtiyati haciz) at the outset, before or simultaneously with filing the main claim. This requires demonstrating a credible claim and providing security to the court. Acting within the first days of a dispute - before the counterparty is notified - is often the difference between a collectible judgment and a worthless one.

How long does it take and what does it cost to enforce a foreign arbitral award in Turkey?

Enforcement of a New York Convention award in Turkey, where uncontested, can be completed in six to twelve months at first instance. Contested enforcement - where the respondent raises public policy or other objections - can take 18 months or longer, with potential appeals extending the timeline further. Legal costs for enforcement proceedings start from the low thousands of EUR and increase with complexity. The key variable is whether the respondent mounts a substantive challenge. Structuring the underlying arbitration to minimise public policy exposure - by avoiding reliance on grounds that conflict with Turkish mandatory law - reduces enforcement risk and cost.

When should a party choose arbitration over Turkish court litigation for a cross-border commercial dispute?

Arbitration is generally preferable when the dispute involves parties from multiple jurisdictions, when confidentiality matters, when the award needs to be enforceable in more than one country, or when the parties want decision-makers with specific commercial expertise. Turkish court litigation is more practical when the debtor has identifiable assets in Turkey, the claim is straightforward, and speed of enforcement through the icra system is the priority. For contracts not yet signed, building in an ISTAC or ICC arbitration clause with a neutral seat is the standard approach for international commercial agreements with Turkish parties. For existing contracts without an arbitration clause, the parties can agree to arbitrate post-dispute, though this requires the cooperation of the counterparty.

Turkey';s dispute resolution landscape offers genuine options for international businesses - from specialised commercial courts and a modern arbitration framework to a New York Convention enforcement regime. The procedural requirements are specific and unforgiving: mandatory mediation, front-loaded evidence, translation obligations, and limitation periods that differ from most European systems. Choosing the right forum, acting on interim measures promptly, and engaging experienced local counsel from the outset are the three decisions that most consistently determine whether a dispute produces a practical result.
