International Divorce in Turkey: Determining the Applicable Law

An international divorce in Turkey arises when a marriage includes a foreign element, such as the nationality or habitual residence of one or both spouses. The existence of these international connections does not automatically mean that Turkish law will govern the divorce. Before considering the merits of the case, the court must determine both its jurisdiction and the law applicable to the divorce. Retaining a qualified English-speaking lawyer in Fethiye helps expatriates and international couples identify their procedural standing and preliminary cross-border obligations at this initial stage.

The applicable legal framework is set out in the Act on Private International and Procedural Law, Law No. 5718. This legislation regulates the applicable law, the international jurisdiction of Turkish courts, and the recognition and enforcement of foreign judgments in private law matters with a foreign element.

Under Article 14 of Law No. 5718, divorce and separation are primarily governed by the spouses’ common national law. Where both spouses share the same nationality, the divorce is generally governed by the substantive law of that country, even if the proceedings take place before a Turkish court.

If the spouses do not have a common nationality, the court considers their common habitual residence. Where neither a common nationality nor a common habitual residence exists, Turkish law applies. This hierarchy is prescribed by Law No. 5718 and should be assessed before the substantive issues are examined.

Identifying the applicable law is often one of the most important stages of international divorce proceedings. The governing law may affect the grounds for divorce, the legal consequences of divorce, post-divorce maintenance and issues relating to custody. Temporary measures, however, are governed by Turkish law. Consulting an experienced divorce lawyer in Turkey ensures that these substantive rights and conflicts of law are analysed before formal pleadings are filed.

Where Law No. 5718 requires the application of foreign law, Turkish courts apply that law ex officio. The court may request assistance from the parties when determining the content of the foreign law. If the relevant foreign law cannot be established despite all inquiries, Turkish law applies.

How Turkish Courts Determine the Applicable Law

In an international divorce in Turkey, one of the first issues a Turkish court must determine is the law governing the divorce. The court does not select the governing law based on the parties’ preference or the place where the marriage broke down. It applies the conflict-of-law rules under Law No. 5718 to identify the legal system governing the divorce.

The first connecting factor under Article 14 is the spouses’ common national law. Where both spouses are nationals of the same country, the substantive divorce law of that country generally applies. This means a Turkish court may hear the case while applying foreign substantive law to the divorce itself.

If the spouses do not share the same nationality, the court considers whether they have a common habitual residence. Habitual residence is assessed by examining where the spouses have established the centre of their lives on a stable and continuous basis. The assessment depends on the facts of each case, not solely on nationality, registration records or immigration status.

Where there is no common nationality and no common habitual residence, the divorce is governed by Turkish law. This approach ensures that every international divorce before a Turkish court can be determined under a clearly identifiable legal system, even where the spouses have different nationalities and no shared habitual residence.

Turkish courts are required to ascertain and apply foreign law where Law No. 5718 points to a foreign legal system. The court may request assistance from the parties, obtain expert input or use official channels to determine the content of the applicable foreign law. If the relevant foreign law cannot be established despite all inquiries, Turkish law applies under Article 2 of Law No. 5718.

The fact that foreign substantive law applies does not transfer the proceedings to another jurisdiction. The divorce continues before the Turkish court, which conducts the case under Turkish procedural law. Issues concerning procedure, evidence, hearings and the management of the proceedings are therefore governed by Turkish law.

Article 5 of Law No. 5718 establishes a limited public policy exception. A Turkish court may refuse to apply a provision of foreign law where its application would be clearly incompatible with the fundamental principles of Turkish public policy. Accordingly, the public policy exception is applied only in exceptional circumstances and does not permit Turkish courts to disregard foreign law simply because Turkish legislation provides a different solution.

Jurisdiction, Recognition of Foreign Decisions and Practical Considerations

Determining the applicable law does not, by itself, establish whether a Turkish court has jurisdiction to hear an international divorce case. Jurisdiction and applicable law are separate legal questions under Turkish private international law. A Turkish court must first satisfy the jurisdictional requirements before considering which substantive law governs the divorce.

The international jurisdiction of Turkish courts in private law matters with a foreign element is governed by Law No. 5718. In divorce proceedings, the court also considers the relevant domestic jurisdiction rules applied to family law disputes. The appropriate forum should therefore be assessed by reference to both the international element and the factual connection of the spouses with Turkey.

It is possible for a Turkish court to have jurisdiction even where the divorce is governed by foreign substantive law. Equally, the fact that Turkish law applies under Article 14 does not automatically resolve the question of forum. Jurisdiction and applicable law must be examined independently before the court proceeds with the merits of the case.

Foreign couples should also consider whether a divorce judgment issued in Turkey will need to be recognised in another country. Recognition requirements vary between jurisdictions and are governed by the domestic law of the country where the judgment will be relied upon. A valid Turkish divorce judgment may therefore require separate procedural steps abroad.

Where a divorce has already been granted by a foreign court or administrative authority, it does not automatically produce all legal effects in Turkey. Depending on the circumstances, the decision may need to be recognised by a Turkish court or registered through the competent civil registration authority. The correct route depends on the nature of the decision, the parties’ status and the legal effect sought in Turkey.

Judicial recognition and enforcement of foreign court decisions are governed by Law No. 5718. Recognition is generally relevant where the foreign judgment is relied upon for status or legal consequences in Turkey. Enforcement may be required where the decision contains executable obligations, such as certain maintenance or property-related orders.

For foreign couples, practical considerations often extend beyond the divorce itself. Asset division, child-related issues, maintenance and the recognition of related court orders may each require separate legal assessment. Where more than one jurisdiction is connected to the marriage, careful consideration should be given to jurisdiction, applicable law and recognition before proceedings are commenced. Working with a dedicated divorce lawyer in Fethiye provides clear regional and procedural guidance when addressing these multijurisdictional family disputes.

Legal Issues Affecting Foreign Couples During Divorce Proceedings

The applicable law may affect several issues connected with the dissolution of the marriage. Under Article 14 of Law No. 5718, the grounds and consequences of divorce and separation are governed by the same conflict-of-law framework. This means that the court must first identify the governing law before assessing the substantive claims arising from the divorce.

Maintenance claims between divorced spouses are also considered within this framework. Where Article 14 points to a foreign legal system, the Turkish court may need to assess post-divorce maintenance under that foreign substantive law. Temporary measures requested during the proceedings, however, are governed by Turkish law.

Custody issues arising from divorce are addressed separately under Article 14. Where children are involved, the court must consider the applicable law while ensuring that the outcome is compatible with Turkish public policy. In practice, the child’s welfare remains a central consideration in custody-related decisions before Turkish courts.

Asset-related matters may require a separate legal assessment. The law governing divorce does not automatically resolve every question concerning matrimonial property, jointly owned assets or assets located in different countries. Where immovable property is situated in Turkey, Turkish property rules and land registry practice may become relevant to the legal effect sought.

Foreign couples should also consider the evidential requirements of proceedings before a Turkish court. Marriage certificates, civil registry records, identity documents and foreign judgments may need to be apostilled, translated and submitted in a form accepted by the court. These requirements concern the conduct of the proceedings and are therefore handled under Turkish procedural law.

In cross-border marriage matters involving Turkey, the applicable law divorce assessment should be completed before claims are framed in the petition. A claim that appears straightforward under one legal system may require different grounds, evidence or supporting documents under another. For foreign couples law questions, the correct starting point is to identify the governing law, the competent forum and the legal effect sought in Turkey.

FAQ

Which law applies if one spouse is Turkish and the other is foreign?

Where one spouse is Turkish and the other is foreign, there is no common national law. The court therefore considers whether the spouses have a common habitual residence. If no common habitual residence exists, Turkish law applies under Article 14 of Law No. 5718.

Does living in Turkey mean Turkish law will automatically apply to the divorce?

No. Living in Turkey does not automatically mean that Turkish law governs the divorce. The court first examines common nationality, then common habitual residence, and Turkish law may apply where the hierarchy under Article 14 leads to that result.

Does a foreign divorce judgment automatically take effect in Turkey?

Not in every case. Depending on the nature of the decision and the legal effect sought, it may need court recognition or administrative registration before it can be relied upon in Turkey.

Summary

International divorce in Turkey requires a separate assessment of jurisdiction and applicable law. Under Law No. 5718, Turkish courts determine the governing law by examining common nationality, common habitual residence and, where neither exists, Turkish law. A Turkish court may therefore hear the case while applying foreign substantive law. Recognition, administrative registration and cross-border consequences should also be considered where the marriage or divorce has legal effects in more than one country.
