Recognition and enforcement of foreign arbitral awards in Turkey is one of the most important topics in cross-border dispute resolution. A favorable award is valuable only if it can be turned into a practical result, and that usually means recognition, enforcement, or both in the country where the losing party or its assets are located. In Turkey, that process is shaped mainly by two pillars: the 1958 New York Convention and Law No. 5718 on International Private and Procedural Law. Turkey acceded to the New York Convention on 2 July 1992, and it entered into force for Turkey on 30 September 1992. Turkey also made the reciprocity and commercial reservations permitted by Article I(3) of the Convention.
That treaty framework matters because the New York Convention is still the leading international instrument for cross-border award enforcement. Under Article I, the Convention applies to awards made in the territory of a state other than the state where recognition and enforcement are sought, and it also applies to awards not considered domestic in the enforcing state. Article III requires contracting states to recognize awards as binding and enforce them under local procedural rules, while also prohibiting substantially more onerous conditions or higher fees than those imposed for domestic awards. Article IV sets the documentary package for enforcement, and Article V limits the grounds on which recognition or enforcement may be refused.
Turkey’s domestic legislation complements that treaty structure. Law No. 5718 states at the outset that international treaty provisions to which the Republic of Turkey is a party are reserved. The same law then separately regulates foreign arbitral awards in Articles 60 to 63. Taken together, those provisions mean that, in practice, the New York Convention is the first reference point where its scope is satisfied, while Law No. 5718 provides the domestic procedural and fallback framework for foreign arbitral award recognition and enforcement in Turkey. That is an inference drawn from Article 1(2) and Articles 60 to 63 of Law No. 5718 read together.
This distinction is not academic. Businesses, investors, contractors, energy companies, logistics firms, technology suppliers, and international traders often discover that the arbitration clause was the easy part. The hard part comes later: identifying the right Turkish court, filing the correct documents, overcoming procedural objections, and resisting arguments based on public policy, arbitrability, due process, or the status of the award at the seat. In Turkish practice, a foreign arbitral award is not enforced automatically. But the system is structured, relatively clear, and internationally recognizable if the application is prepared properly.
The Legal Sources Governing Foreign Arbitral Awards in Turkey
The first major source is the New York Convention itself. Its importance in Turkey is reinforced by the fact that Turkey is a contracting state and that Turkish law reserves treaty provisions in matters of foreign decisions. Turkey’s reservation regime is also highly important in practice. According to the United Nations Treaty Collection and UNCITRAL status materials, Turkey applies the Convention on the basis of reciprocity and only to disputes arising out of legal relationships regarded as commercial under Turkish national law. That means not every foreign arbitral award in the abstract falls within the Convention exactly as it would in a state with no reservations.
The second major source is Law No. 5718. Article 60 provides that foreign arbitral awards may be enforced in Turkey if they have become final and enforceable, or if they are binding on the parties. Article 63 then states that recognition of foreign arbitral awards is also subject to the same rules that govern enforcement. These provisions are the core domestic gateway for foreign awards in Turkey.
A third source becomes relevant by contrast rather than direct application: the International Arbitration Law No. 4686. That law applies to disputes with a foreign element where the seat of arbitration is Turkey, or where the parties or tribunal choose that law. It also states that it does not apply to disputes concerning rights in rem over immovables in Turkey or disputes not subject to party disposition. Most importantly for present purposes, Article 15 of that law provides that awards under that regime are challenged only by a set-aside action before the competent Turkish court. That helps explain the practical divide in Turkish law between Turkey-seated international awards, which are primarily subject to annulment control, and truly foreign awards, which are subject to recognition and enforcement proceedings under Law No. 5718 and the Convention.
What Counts as a Foreign Arbitral Award in Turkish Practice?
The New York Convention applies to awards made outside the state where enforcement is sought, and also to awards that are not treated as domestic in that enforcing state. Turkish domestic law, meanwhile, separately regulates “foreign arbitral awards” in Articles 60 to 63 of Law No. 5718. In practical Turkish analysis, the key distinction is whether the award is being treated as a foreign award for enforcement purposes, rather than as a Turkey-seated award subject to the Turkish annulment regime. This is why counsel should always examine the seat, the procedural law of the arbitration, and the legal route already taken at the seat before deciding whether the award belongs in a Turkish set-aside discussion or in a Turkish recognition-and-enforcement proceeding.
This distinction has real consequences. A Turkey-seated international award under Law No. 4686 is attacked through annulment, and Article 15 states that filing the set-aside action automatically suspends enforcement of that award. A foreign arbitral award, by contrast, is not “annulled” by Turkish courts as a primary remedy. Instead, the Turkish court decides whether to recognize or enforce it under the limited grounds stated in Law No. 5718 and, where applicable, the Convention. That is one of the most important structural points in Turkish arbitration law.
Why Recognition and Enforcement Matter Separately
Turkish law states that recognition of foreign arbitral awards is subject to the same provisions as enforcement. That means the legal route is closely aligned, even though the practical objective may differ. Article 63 does not create a looser or separate recognition test. It channels recognition back into the enforcement framework. For users of the Turkish system, the practical message is straightforward: even when the immediate goal is not direct execution against assets, the award creditor should treat recognition work with the same seriousness and documentation discipline as enforcement work.
That also means parties should not assume that recognition is merely symbolic or effortless. Under Turkish law, recognition of foreign arbitral awards is not detached from the refusal grounds, procedural rules, and court scrutiny that govern enforcement. The statute deliberately aligns them.
Which Turkish Court Is Competent?
Jurisdiction in Turkey is a central procedural issue. Article 60(2) of Law No. 5718 states that enforcement of a foreign arbitral award is requested by petition before the civil court of first instance in the place chosen by the parties in writing. If the parties have made no such written agreement, the competent court is the court where the losing party has its domicile in Turkey; if there is no domicile, then the place where that party resides; if neither exists, then the place where assets subject to execution are located.
This rule is highly practical. It means Turkish jurisdiction for foreign arbitral award enforcement can be anchored by party agreement, by the award debtor’s personal connecting factors in Turkey, or by the location of executable assets. For award creditors, asset mapping is therefore not merely an enforcement-stage exercise; it can determine forum competence from the very start of the recognition and enforcement case.
The law uses the term asliye mahkemesi, which in practice means the court of first instance with civil jurisdiction. So when international parties ask where a foreign award is enforced in Turkey, the short legal answer is: the competent civil court of first instance identified under Article 60(2).
What Documents Must Be Filed?
Documentation is one of the most decisive parts of the Turkish process. Article IV of the New York Convention requires the applicant to supply the duly authenticated original award or a duly certified copy, together with the original arbitration agreement or a duly certified copy. If those documents are not in an official language of the enforcing state, the applicant must also provide a translation certified by an official or sworn translator or by a diplomatic or consular agent.
Turkish law closely reflects that approach. Article 61 of Law No. 5718 requires the applicant to attach, with copies matching the number of opposing parties, the original arbitration agreement or clause or its duly certified copy; the original award that has become final and enforceable or binding, or its duly certified copy; and translated, duly certified versions of those documents. Turkish practice is therefore document-heavy at the filing stage, and a casual or incomplete package can slow the case before the court ever reaches the refusal grounds.
This is one reason why award creditors should prepare the Turkish filing package before starting execution planning. Authentication, certification, translation quality, and consistency between the award text and the arbitration agreement can all become outcome-relevant. In cross-border matters, this preparation often determines whether the Turkish enforcement process feels efficient or unexpectedly difficult.
The Procedural Route in Turkish Courts
Article 61(2) of Law No. 5718 provides that, in enforcement of foreign arbitral awards, Articles 55, 56, and 57 of the same law apply by analogy. Those provisions, originally drafted for foreign court judgments, are therefore procedurally significant here as well. Article 55 states that the enforcement petition is served on the opposing party together with the hearing date, and that the matter is examined under the simple procedure. Article 56 states that the court may order full or partial enforcement or reject the request. Article 57 adds that a foreign decision whose enforcement is granted is executed like a Turkish judgment, and that appeal against the acceptance or rejection decision is governed by general rules, with the appeal staying enforcement.
This structure matters because it shows that the Turkish court is not conducting a fresh trial on the merits of the underlying dispute. It is conducting a specialized enforcement review under a simplified procedural framework. Once enforcement is granted, the foreign arbitral award is executed in Turkey like a Turkish judgment. But until that point, the award creditor still has to pass through the statutory filters.
The appeal rule is also practically important. Because Article 57 says appeal suspends enforcement, a favorable first-instance enforcement ruling does not instantly eliminate all procedural risk. Award creditors need to account for the possibility of appellate delay when advising on collections strategy in Turkey.
The Main Refusal Grounds Under Turkish Law
Article 62 of Law No. 5718 is the core refusal provision. It states that the Turkish court shall refuse enforcement if there was no arbitration agreement or no arbitration clause in the main contract; if the award is contrary to general morality or public policy; if the dispute was not arbitrable under Turkish law; if one of the parties was not properly represented before the tribunal and did not later expressly accept the proceedings; if the respondent was not duly informed of the arbitrator selection or was deprived of the opportunity to present its claims and defenses; if the arbitration agreement is invalid under the law chosen by the parties, or in the absence of such choice, under the law of the country where the award was rendered; if the appointment of arbitrators or the procedure used was contrary to the parties’ agreement, or in the absence of agreement, contrary to the law of the place of arbitration; if the award decided matters outside the arbitration agreement or exceeded its scope, in which case only that part may be refused; or if the award has not become final, enforceable, or binding under the applicable law or procedure, or if it has been annulled by the competent authority at the place where it was made.
These grounds closely resemble the refusal grounds in Article V of the New York Convention. Article V(1) addresses incapacity or invalid arbitration agreement, lack of proper notice or inability to present the case, excess of scope, improper composition of the tribunal or procedure, and the non-binding, annulled, or suspended status of the award. Article V(2) adds two court-facing grounds: non-arbitrability of the subject matter under the law of the enforcing state and incompatibility with that state’s public policy. The Turkish statutory list is therefore broadly aligned with the Convention, while using Turkish legislative language such as general morality and Turkish public policy.
That alignment is a major reason the Turkish framework is considered internationally legible. A foreign award creditor coming from a New York Convention practice environment will recognize most of the core defenses immediately. But recognition is not automatic merely because the categories are familiar. Turkish courts still analyze those defenses through Turkish law and Turkish public policy standards.
Public Policy and Arbitrability in Turkey
Public policy is one of the most frequently invoked defenses in enforcement cases worldwide, and Turkey is no exception. Both the New York Convention and Law No. 5718 preserve public policy review. Under the Convention, enforcement may be refused if recognition or enforcement would be contrary to the public policy of the enforcing state. Under Article 62 of Law No. 5718, the court must refuse enforcement if the award is contrary to general morality or public policy.
The importance of this ground lies in its dual nature. It is both necessary and potentially elastic. Turkey does not allow public policy to disappear from the enforcement analysis, but neither the Convention nor Law No. 5718 turns enforcement into a full merits appeal. So, in principle, Turkish public policy review is meant to police serious incompatibilities with core Turkish legal order values, not to let the losing party relitigate ordinary contractual or evidentiary disputes. That is a reasoned inference from the limited structure of Article V of the Convention and Article 62 of Law No. 5718.
Arbitrability is similar. Under Article V(2)(a) of the Convention and Article 62(c) of Law No. 5718, enforcement may fail if the subject matter is not capable of settlement by arbitration under Turkish law. This is why enforcement strategy must begin long before the award arrives in Turkey. If the underlying dispute sits near a non-arbitrable area, that risk has to be assessed at contract drafting and at case-filing stage, not only during enforcement.
Burden of Proof and Defense Strategy
Article 62(2) of Law No. 5718 expressly allocates the burden of proof for several refusal grounds to the party against whom enforcement is sought. Those include improper representation, lack of proper notice or deprivation of defense rights, invalidity of the arbitration agreement under the applicable law, defects in tribunal composition or arbitral procedure, excess of scope, and the award’s lack of finality, enforceability, or binding effect, or its annulment at the seat.
This burden rule is strategically important. It means the award debtor cannot rely on broad assertions alone for those defense-type grounds. The statute expects proof. At the same time, the law does not place every issue on the debtor. Public policy, morality, and arbitrability remain court-centered grounds within the statutory scheme. As a practical matter, this creates a familiar enforcement structure: debtor-driven proof for classic Article V(1)-type defenses, and court-facing scrutiny for core system-protection issues.
For award creditors, this burden structure has a clear implication: the initial petition should anticipate the defenses most likely to be raised and neutralize them early with a clean record on notice, representation, tribunal constitution, applicable arbitration law, and the award’s current status at the seat.
Turkey’s Reservations Under the New York Convention
Turkey’s Convention reservations are not symbolic. According to the UN Treaty Collection and UNCITRAL status materials, Turkey applies the Convention only on the basis of reciprocity and only to disputes arising out of legal relationships regarded as commercial under Turkish law.
The reciprocity reservation means the Convention route is limited to awards made in another contracting state. The commercial reservation means the Convention route is also limited to disputes that Turkish law regards as commercial. These reservations do not mean foreign arbitral awards outside those boundaries are automatically impossible to enforce in Turkey; rather, they mean the Convention itself does not necessarily do the work in those cases. Law No. 5718 remains important because it separately regulates foreign arbitral awards and reserves treaty provisions without collapsing the domestic regime into the treaty. That is an inference from the reservation texts, Convention Article I(3), and Law No. 5718 Articles 1 and 60 to 63.
In practical terms, lawyers should always run a two-step analysis in Turkey: first, whether the New York Convention applies as a treaty matter, and second, how Law No. 5718 structures the local court process and any residual or supplementary analysis.
Foreign Awards and Turkish-Seated Awards Are Not Enforced the Same Way
One of the most common mistakes in practice is treating every arbitral award as if the Turkish route were identical. It is not. Law No. 4686 applies to international arbitrations with a foreign element where the seat is Turkey, or where that law is chosen. Article 15 of that law provides that only a set-aside action may be brought against such an award, and that filing the set-aside action automatically stays enforcement.
A foreign arbitral award under Law No. 5718 follows a different path. The Turkish court is not asked to annul it as the primary supervisory court. Instead, it is asked to recognize or enforce it, subject to the refusal grounds in Article 62 and the Convention. This distinction matters for timing, defensive strategy, and client expectations. Losing parties often assume they can “attack the award” in Turkey the same way they would attack a Turkey-seated award. But for foreign awards, the Turkish proceeding is generally an enforcement proceeding, not a full supervisory review of the award as such.
Security for Costs and Other Practical Issues
A practical point sometimes overlooked in cross-border enforcement is security for costs. Article 48 of Law No. 5718 states that foreign natural and legal persons who file suit, intervene in proceedings, or commence execution in Turkish courts must provide security in an amount determined by the court for litigation and execution costs and potential losses of the other side. The court exempts the foreign party from security on the basis of reciprocity.
That rule can matter in foreign award enforcement cases, especially where the award creditor is a foreign company with no Turkish presence. Counsel should therefore assess not only the substantive enforceability of the award, but also whether a security issue may arise procedurally and whether reciprocity-based exemption arguments are available.
Another practical point is translation quality. Both the Convention and Law No. 5718 require translated and duly certified documents when the originals are not in the relevant language. In practice, inaccurate or incomplete translation can create avoidable disputes around scope, dispositive language, costs, or binding effect. So translation should be treated as part of the legal strategy, not as a clerical afterthought.
A Practical Roadmap for Enforcing a Foreign Arbitral Award in Turkey
A practical Turkish enforcement roadmap usually looks like this. First, identify whether the award falls within the New York Convention as applied by Turkey, taking into account Turkey’s reciprocity and commercial reservations. Second, identify the competent Turkish civil court of first instance under Article 60(2), whether by party agreement, debtor domicile or residence, or asset location. Third, prepare the documentary package required by Article IV of the Convention and Article 61 of Law No. 5718, including certified translations. Fourth, analyze in advance whether the debtor is likely to raise Article 62 defenses, especially notice, representation, scope, validity of the arbitration agreement, procedure, or set-aside activity at the seat. Fifth, build the filing strategy around assets and expected timing, remembering that appeal against the enforcement decision stays execution under Article 57 by analogy.
The most successful applications in Turkey are usually the ones that look boring in the best sense: clean arbitration clause, clean award, clean certification, clean translation, clear seat history, and no surprises about the award’s status. Enforcement in Turkey is most difficult when the creditor tries to repair at the filing stage what should have been fixed during the arbitration or at the seat.
Conclusion
Recognition and enforcement of foreign arbitral awards in Turkey rests on a clear but technical framework. The New York Convention supplies the international backbone, and Turkey applies it with reciprocity and commercial reservations. Law No. 5718 then provides the domestic court route, the competent forum rules, the filing package, the procedural path, and the refusal grounds for foreign arbitral awards. Turkish-seated international awards under Law No. 4686 follow a different route through set-aside rather than foreign-award enforcement.
For businesses and counsel, the main lesson is simple. A foreign arbitral award is not self-executing in Turkey, but it is enforceable through a structured legal route that is recognizable to international arbitration users. The decisive issues are usually not abstract. They are practical: Convention coverage, court competence, document preparation, translation, the award’s status at the seat, and advance handling of refusal grounds. In Turkish enforcement practice, careful preparation often matters as much as the award itself.
