Enforcing Foreign Arbitral Awards in Turkey: New York Convention and Court Procedure

1. Start with the award, not the collection demand

A foreign award holder often begins with a practical question: can this award be used against a bank account, receivable, shareholding or other asset in Türkiye? The reliable answer starts one step earlier. The award must first be classified, the governing recognition route must be identified, and any Turkish court judgment required for enforcement must be obtained before coercive execution begins.

That classification cannot be made from the award’s language, the parties’ nationality or the arbitral institution’s name. Counsel should identify the legal seat, the law governing the arbitral procedure, the award’s status under that law, the nature of the underlying relationship and any treaty regime that displaces the ordinary commercial-award framework.

An international award seated in Türkiye may fall under the International Arbitration Law No. 4686, including its own annulment and enforceability rules. A Türkiye-seated arbitration without the foreign element required by that law instead falls within Part Eleven of the Code of Civil Procedure. Neither category should be treated as a foreign award merely because a party is foreign, the proceedings were conducted in English or the institution has an international name.

An ICSID Convention award also requires separate treatment. Its recognition and enforcement mechanism is not the ordinary New York Convention route used for commercial awards. The first file review should therefore record the seat, the procedural law, the source of jurisdiction, the type of award and the relief granted before discussing a Turkish filing strategy.

2. Does the New York Convention apply in Türkiye?

The New York Convention applies in principle to awards made outside the State where recognition or enforcement is sought and to awards treated as non-domestic in that State. Türkiye acceded to the Convention on 2 July 1992, subject to the two reservations permitted by Article I(3). Both reservations must be tested rather than assumed away.

Under the reciprocity reservation, Türkiye applies the Convention to awards made in the territory of another Contracting State. The relevant place is the legal place of the award, usually derived from the seat, rather than the city where a hearing occurred or the institution maintains its office. The origin State’s current Convention status should be checked in the United Nations Treaty Collection for the actual filing date.

Under the commercial reservation, the dispute must arise from a legal relationship considered commercial under Turkish law. A contract’s label and its characterization under another legal system may be useful background, but they do not complete the Turkish-law analysis. The pleaded route should state why the underlying relationship falls within the reservation.

If the Convention does not apply, Articles 60 to 63 of the Private International Law and International Civil Procedure Act No. 5718, commonly referred to as MÖHUK, provide the domestic statutory framework for foreign arbitral awards. Article 1(2) of that Act preserves applicable treaties. Convention Article VII also preserves other applicable arrangements and a party’s right to rely on a more favourable route available in the enforcement State.

Those provisions do not automatically select the best route or permit elements of different regimes to be combined without analysis. The application should identify its legal basis and compare any alternative route on the facts. The reciprocity condition for foreign court judgments under MÖHUK Article 54 should not be imported into the foreign-award provisions as their general threshold.

3. Recognition, enforcement and execution are different stages

Recognition, enforcement and execution answer different questions. Recognition concerns the award’s legal effect in Türkiye. Enforcement, sometimes called a declaration of enforceability, is the court process that permits coercive use of the award. Execution is the later asset process conducted under Turkish enforcement law once an enforceable title exists.

MÖHUK Article 63 subjects recognition of a foreign arbitral award to the provisions governing enforcement. Where the operative part contains both declaratory and payment relief, each part should be classified by the effect sought in Türkiye. A request for recognition alone should not be described as immediate collection, and a payment award should not be sent directly to an enforcement office as though the Turkish court stage had already occurred.

Under MÖHUK Article 60, the domestic statutory threshold refers to an award that is final and enforceable or binding on the parties. The proof required depends on the law and rules governing the award. A court-style certificate of finality should not be demanded if that system has no such document, and the award’s status should not be inferred from the date printed on it.

Once a Turkish enforcement judgment covers the award, MÖHUK Articles 57 and 61 provide that it is executed like a Turkish judgment. That still does not identify assets, establish ownership, defeat third-party rights or resolve immunity. The award, the Turkish judgment and the asset-specific execution file remain separate parts of one recovery project.

4. Which Turkish court and which procedure?

For the MÖHUK route, Article 60(2) first gives effect to the parties’ written agreement on the place where enforcement proceedings may be brought. Without such a choice, venue follows the respondent’s domicile in Türkiye, then its residence, and then the place where property capable of execution is located. The factual basis for venue should be documented rather than copied from an old contract address.

Subject-matter jurisdiction is a separate question. Article 5 of Law No. 5235 places foreign-award recognition and enforcement proceedings before a commercial-court panel where a commercial court of first instance exists. Current court organization, local distribution decisions and the relief actually requested should nevertheless be checked before filing; the statute alone does not safely identify a particular courthouse or chamber.

MÖHUK Article 61(2) applies Articles 55 to 57 by analogy. On that basis, the petition and hearing date are served on the opposing party and the matter is examined under the simple procedure. Real response dates and hearing timing depend on effective service and the court’s orders, so a general guide cannot calculate a party’s deadline.

The opposing party may rely on absence of the enforcement conditions and, through the incorporated provisions, on partial or complete performance or another obstacle to performance. A Turkish court may grant full or partial enforcement or reject the request, subject to the legal conditions for each result.

The decision granting or refusing enforcement is subject to the general appellate framework. MÖHUK Article 57(2), applied through Article 61(2), states that appellate review stays performance. The available remedy, service date, finality position and effect on a particular execution step must be determined from the current law and the actual docket instead of a guessed universal timetable.

5. The application file: award, agreement, certification and translation

Convention Article IV requires the applicant, when applying, to supply the duly authenticated original award or a duly certified copy and the original arbitration agreement or a duly certified copy. If those documents are not in an official language of the enforcement State, the Convention calls for a translation certified by an official or sworn translator or by a diplomatic or consular agent. For a Turkish filing, the accepted Turkish translation and the authority of the certifier should be confirmed before submission.

MÖHUK Article 61 is more explicit about the domestic application file. It calls for the original or duly certified arbitration agreement, the original or duly certified award showing that it meets the statutory finality, enforceability or binding threshold, duly certified translations and copies for each opposing party. The status evidence may take different forms under different arbitral laws and rules, so there is no safe universal “finality certificate” template.

The complete arbitration agreement matters. That may include a clause in the main contract, amendments, incorporated general conditions and any separate submission agreement. The file should also include the complete award, not only the dispositive page, because scope, party identity, procedural history and the tribunal’s treatment of the agreement may be relevant to a limited refusal issue.

An apostille has a narrower function than is sometimes assumed. For a document within the Apostille Convention, it authenticates the signature, the capacity in which the signer acted and, where applicable, the seal or stamp. It does not establish that an arbitral award is correct, binding, final or enforceable.

An arbitral award can also be a private document, which makes the relevant public or notarial certification chain important. Apostille is neither universally required nor universally sufficient. The document type, issuing authority, origin State, treaty relationship, current objections and any consular legalization route must be checked together with Convention Article IV and MÖHUK Article 61.

A working document schedule should identify each original, copy, certification, translation, status record and service copy. Electronic awards and certified electronic copies require their own form analysis.

6. Service and the right to present the case

The Turkish enforcement petition and hearing date must be served on the opposing party. If a Turkish judicial document must be transmitted abroad, the 1965 Hague Service Convention may govern where its territorial and subject-matter requirements are met. The destination State’s current status, declarations, objections, Central Authority details and available transmission method must be checked for the particular service request.

Service in the Turkish proceeding is distinct from notice in the arbitration. Under New York Convention Article V(1)(b), enforcement may be refused if the party against whom the award is invoked was not given proper notice of the arbitrator’s appointment or the arbitral proceedings, or was otherwise unable to present its case. MÖHUK contains a corresponding ground focused on representation, notice and the opportunity to defend.

Non-participation in the arbitration does not establish the answer by itself. The inquiry should reconstruct how the tribunal was appointed, which address and method were used, what was transmitted, when it was received, which language was used, whether representation existed and what real opportunity remained to answer. The material link is between the alleged notice defect and the inability to present the case, not simply the existence of a default award.

The Hague Service Convention does not decide the validity of arbitral notice or the merits of enforcement; its role concerns transmission of judicial documents within its scope.

7. The court applies limited refusal grounds

Enforcement is not a new trial of the contract dispute. New York Convention Article V contains the refusal grounds, and the UNCITRAL Secretariat Guide explains that an enforcement court may not revisit the tribunal’s factual or legal merits merely because it would have decided them differently. The Turkish court still conducts the limited inquiries assigned to it by the applicable route.

At the request of the resisting party, Article V(1) addresses capacity and validity of the arbitration agreement, proper notice and the opportunity to present the case, excess of mandate, tribunal composition or procedure, and whether the award has become binding or has been set aside or suspended. Agreement validity is tested under the law chosen by the parties or, absent such choice, the law of the country where the award was made. Capacity may engage a different applicable law and should not be collapsed into the agreement-validity question.

The MÖHUK list overlaps but must be pleaded in its own terms. It includes absence of an arbitration agreement or clause, specified validity defects, representation or notice failures, procedural non-compliance, decisions beyond the submission and defects in the award’s status.

A procedural difference does not automatically require refusal. The relevant comparison is between the procedure actually followed and the parties’ agreement or, where there was no agreement on that point, the law of the seat. The objection should identify the material mismatch and connect it to a Convention or statutory ground.

Where the award decides matters beyond the submission, Convention Article V(1)(c) permits recognition and enforcement of the separable decisions that remain within scope. MÖHUK directs refusal for the excess portion. Partial enforcement requires a genuinely severable operative result; it cannot be used to rewrite the tribunal’s decision or create a new allocation of relief.

Under Article V(1), the party resisting enforcement supplies proof of the listed party-invoked grounds. Arbitrability and public policy may be considered under Article V(2). MÖHUK Article 62(2) also assigns the burden for its listed representation, notice, validity, procedure, scope and status grounds to the respondent, but no single burden statement should be generalized to every preliminary document or procedural issue.

The word “may” in the Convention’s refusal clause should not be turned into a promise that the court will enforce an award despite an established ground. It confirms that the Convention is an enforcement framework, not an outcome warranty. The Turkish court retains the assessment that the Convention and domestic law allocate to it.

8. Set-aside proceedings, adjournment and security

Proceedings at the seat and enforcement proceedings in Türkiye have different functions. A set-aside court addresses the award under the supervisory law of the seat, while the Turkish court addresses recognition or enforcement under the applicable Turkish route.

Convention Article V(1)(e) permits refusal if the award has not yet become binding or has been set aside or suspended by the competent authority in the country in which, or under the law of which, it was made. Binding status is not automatically the same as a domestic concept of formal finality or a second declaration of enforceability at the seat. The award rules, seat law and operative orders should be read rather than summarized from a docket label.

A pending set-aside application, an order suspending the award and a judgment setting it aside are different procedural facts. The Turkish file should contain the complete application or order, its effective date, any appellate position and a reliable explanation of its present effect. A party should not report an award as “annulled” merely because a challenge has been filed.

If a set-aside or suspension application is pending before the authority described in Article V(1)(e), Article VI permits the enforcement court to adjourn its decision. On the enforcement applicant’s request, the court may also order the other party to provide suitable security. Both decisions are discretionary under the Convention text, so neither an adjournment nor security in a particular form or amount can be guaranteed.

9. Arbitrability, public policy and no merits review

The Turkish court may refuse recognition or enforcement if the subject matter is not capable of settlement by arbitration under Turkish law. That is an enforcement-State inquiry. The precise relief and legal relationship should be classified rather than labelled non-arbitrable by association with a regulated sector.

Turkish arbitration statutes exclude disputes concerning rights in rem in immovable property situated in Türkiye and matters that are not subject to the parties’ disposition. Contractual payment claims connected with a property transaction may require an analysis different from a request that directly determines a right in rem. The statutory wording should therefore be applied to the claims and operative relief in the actual award.

Public policy is also a refusal ground under both the Convention and MÖHUK. It is not a general permission to retry the evidence, substitute Turkish contract interpretation or treat every error of law and every mandatory rule as decisive. This article makes no proposition about the outcome of an unverified Turkish court precedent; a case-based argument should rely on the full text, current authority and a close factual comparison.

The rule against merits review has boundaries. A court may examine the arbitration agreement, notice and the right to present the case, the tribunal’s mandate, arbitrability, public policy and the award’s binding or set-aside status to the extent the governing instrument permits. It should not decide whether the tribunal chose the better factual inference or commercial interpretation under the guise of those grounds.

Each objection should identify the applicable provision, the relevant record, the fact to be proved and the requested consequence. A broad submission that the tribunal was simply wrong invites a merits debate that the framework does not authorize.

10. Fees, applicant security, limitation and preservation measures

Convention Article III prevents Contracting States from imposing substantially more onerous conditions or higher fees on Convention awards than on domestic awards. Turkish Fees Law Article 3 addresses court fees for foreign arbitral awards according to the award’s nature. The current tariff, the relief sought, the dispute value and current binding authority must be reviewed at filing; this guide does not classify the fee as fixed or proportional for every case.

Court fees are only one cost component. Certified translation, certification or legalization, foreign service, expert or technical handling, potential applicant security, appellate steps and later execution each have a different legal and factual basis. A responsible estimate needs the complete award, party locations, document chain, claimed relief and known asset steps.

MÖHUK Article 48 requires security from foreign natural or legal persons who litigate, intervene or pursue execution in Türkiye and requires exemption where reciprocity is established. The Code of Civil Procedure separately regulates security in its own field. Nationality, domicile, treaty or reciprocity position, legal aid and procedural posture must be reviewed before anyone states that security is required, exempt or likely to be a particular amount.

The New York Convention does not create one worldwide limitation period for filing an enforcement request. The UNCITRAL Guide records that national procedural law may supply time limits. Applicable-law characterization should be undertaken as soon as enforcement is contemplated, without presenting a single borrowed period as universally controlling.

Turkish Enforcement and Bankruptcy Law Article 39 separately provides that judgment-based execution becomes time-barred ten years after the last execution act. That post-judgment rule should not be advertised as a universal ten-year period for starting the recognition or enforcement action. Award limitation, the Turkish enforcement judgment and subsequent execution must be analyzed as distinct stages.

An enforcement filing also does not freeze assets. A provisional injunction under the Code of Civil Procedure or provisional attachment under the Enforcement and Bankruptcy Law requires its own statutory basis and proof. Urgency, the claim type, security and proportionality are fact-specific, and availability should not be assumed from the existence of an award alone.

11. From the Turkish judgment to asset execution

After a Turkish enforcement judgment becomes available for use, a money award proceeds under the rules for judgment-based execution. The enforcement office serves the relevant execution order and the file then turns to the respondent named in the enforceable title and assets legally attributable to that respondent. An objection does not automatically stay every step; a stay requires the conditions of the applicable rule.

Asset planning should begin before the court application but remain evidence-led. Company names, trade names and group relationships do not prove ownership, and asset types carry different attachment and priority questions.

The payment history must also be reconciled. MÖHUK permits the opposing party to rely on partial or complete performance or another obstacle to performance. Currency, interest, costs, value dates, set-offs recognized by the relevant instrument and amounts already received should be presented in a transparent schedule that does not change the award’s operative terms.

Where a State or State-linked entity is involved, recognition, enforcement and immunity from execution must be kept separate. A favorable recognition or enforcement decision does not by itself remove immunity that may protect particular assets. Ownership, use, purpose and the applicable immunity law require an asset-specific review.

Timing depends on matters a general article cannot predict: completeness of the documents, domestic and foreign service, the objections made, parallel proceedings at the seat, appellate review, court workload and the location and condition of assets. No result, collection percentage or completion date can be promised. A useful strategy records the next legal gate and evidence owner at each stage.

12. Special regimes, file checklist, frequently asked questions and sources

ICSID Convention awards illustrate why classification must come first. Contracting States must recognize an ICSID Convention award as binding and enforce its pecuniary obligations as if it were a final domestic judgment, upon presentation of a copy certified by the ICSID Secretary-General to the designated authority. Execution then follows the law governing execution of judgments in the requested State.

That special mechanism applies to an ICSID Convention award, not automatically to Additional Facility awards or every investor-State award. Article 55 also preserves the enforcement State’s law concerning immunity of that State or a foreign State from execution. The instrument, jurisdictional basis and relief must be confirmed before the ICSID route is invoked.

For an ordinary foreign commercial award, the intake file should contain the complete award and dispositive part; the arbitration agreement and incorporated rules; the seat and governing procedural law; proof of binding, final or enforceable status as relevant; any set-aside or suspension record; appointment, notice and service evidence; representation records; the certification, legalization and Turkish translation chain; payment history; and reliable Turkish asset information. Possessing these materials is not proof that enforcement conditions are satisfied, but it permits each condition and risk to be examined without invention.
