Joint Custody from Germany: Does It Apply in Turkey? A Complete 2026 Guide

*This article addresses Turkish law exclusively. Doğru Kanzlei advises on Turkish law under § 207 BRAO and does not advise on German domestic law.*

The divorce was finalised in Germany. The German family court issued a joint custody order — both parents share parental responsibility for their child. Everything is documented, official, legally binding. And then one parent moves to Turkey, or wants to take the child there. Suddenly the other parent discovers a deeply uncomfortable truth: that German court order means nothing in Turkey. Not yet, anyway.

This is the situation that brings many Turkish-German families to us. They have done everything right in Germany — attended court, signed the documents, obtained the order. But they had no idea that a foreign court judgment, however official, has zero automatic legal effect in Turkey. Until a Turkish court formally recognises and declares that order enforceable, the parent in Turkey faces no legal obligation to comply with it. Turkish schools, hospitals, passport offices and authorities are under no duty to act on a German custody ruling.

This guide explains exactly what needs to happen to change that — what the enforcement process involves, what conditions must be met, what documents you need to prepare, and how to run the entire procedure from Germany, the UK, the Netherlands or wherever you live, without a single trip to Turkey.

What Is Tenfiz — and Why Is It Not the Same as Tanıma?

Turkish private international law provides two distinct routes for dealing with foreign court judgments: Tanıma (recognition) and Tenfiz (enforcement). Understanding the difference is essential, because choosing the wrong route — or confusing one for the other — can derail the process entirely.

Tanıma means that a Turkish court accepts a foreign judgment as valid and gives it the force of a final Turkish judgment. It has a declaratory effect — the judgment's existence is confirmed. The most common example is a foreign divorce decree: once recognised in Turkey (Tanıma), the parties are considered legally divorced in Turkey too, and this is registered in the civil records. In some cases, particularly straightforward divorces without custody or financial provisions, Tanıma can even be processed administratively under Article 27/A of the Turkish Civil Registration Law — without going to court at all.

Tenfiz goes a critical step further. It makes the foreign judgment executable — meaning that specific obligations contained in the judgment can actually be enforced by Turkish courts and authorities. Visitation schedules, the right to determine the child's place of residence (known in German law as Aufenthaltsbestimmungsrecht), child maintenance payments — all of these become enforceable in Turkey only after a Tenfiz order is granted.

For any custody order that goes beyond the bare dissolution of a marriage — and joint custody orders almost always do — Tenfiz is required, not just Tanıma. The legal framework governing both procedures is found in Articles 50 to 58 of Turkey's Law on Private International Law and International Civil Procedure, known by its Turkish acronym MÖHUK (Law No. 5718).

⚠️ Important: Without a Tenfiz ruling from a Turkish Family Court, your German custody order carries no legal weight in Turkey. The other parent can ignore it without consequence. Turkish authorities, schools and public bodies are not obligated to act on it in any way.

How Turkey Changed Its Position: The 2016–2017 Turning Point

For decades before 2016, the situation for Turkish-German families was significantly harder. The 2nd Civil Chamber of the Yargıtay — Turkey's Supreme Court — consistently refused to enforce foreign joint custody orders on a straightforward basis: Turkish civil law (TMK, Article 336) only allowed custody to be awarded to one parent following a divorce. Joint custody simply did not exist as a concept in Turkish domestic law, and foreign orders granting it were treated as contrary to Turkish public policy (kamu düzeni), making enforcement impossible.

That changed dramatically in March 2016. With Law No. 6684, published in Turkey's Official Gazette on 25 March 2016, Turkey ratified the Additional Protocol to the European Convention on Contact Concerning Children. This protocol introduced the concept of joint custody into the Turkish legal framework — not directly through a change in the Turkish Civil Code, but through the back door of international treaty law. Under Article 90 of the Turkish Constitution, ratified international agreements carry the force of domestic law; those concerning fundamental rights and freedoms take precedence over conflicting domestic statutes.

The Yargıtay moved quickly. In its landmark ruling of 20 February 2017 (Case No. 2016/15771 E., 2017/1737 K.), the 2nd Civil Chamber reversed its long-standing position: foreign joint custody orders could no longer be automatically rejected as contrary to public policy. Each case would now be assessed individually, with the child's best interests (çocuğun üstün yararı) as the guiding criterion.

That 2017 ruling was a turning point, but not the end of the story. More recent Yargıtay decisions — including 2023/4605 K. and 2024/1916 K. — have reinforced this approach. Turkish courts now regularly enforce joint custody orders issued in Germany and other European countries, provided the legal conditions are properly satisfied and the application is correctly prepared. The direction of travel is clear — but the journey still requires careful navigation.

The Five Conditions a Turkish Court Will Check

Before a Turkish Family Court can grant a Tenfiz order for your German custody judgment, five cumulative conditions must be met under Article 54 of MÖHUK. If any one of these is missing, the court can — and often will — refuse enforcement.

⚠️ Important: Condition 3 — proper notice and participation — is the one most often underestimated and most frequently exploited by the opposing party. If the other parent claims they were never properly served in the German proceedings, or that they did not understand the process, this argument alone can defeat the Tenfiz application. Keep all service documents, hearing notices and correspondence from the German proceedings.

What Documents Do You Need?

Before your Turkish lawyer can file the Tenfiz application, all required documents must be in place — in the right format, with the right certifications. Missing or incorrectly formatted documents are by far the most common cause of delay, and sometimes of outright refusal.

Here is what the Turkish Family Court will require:

1. The German custody judgment — the original court order or a certified copy issued by the German family court. The order must contain all relevant provisions: joint custody, the right to determine the child's place of residence (Aufenthaltsbestimmungsrecht), visitation arrangements (Umgangsrecht) and, if applicable, child maintenance.

2. Certificate of finality (Rechtskraftbescheinigung) — an official document from the German family court confirming that the judgment is final and no longer subject to appeal. Without this, the Turkish court cannot establish that Condition 2 is met.

3. Apostille certification — all German documents must be apostilled under the 1961 Hague Apostille Convention. The apostille is an internationally recognised authentication stamp that certifies the document's validity for use in another country.

4. Certified Turkish translation — every document must be translated into Turkish by a sworn translator registered in Turkey (yeminli tercüman) and notarised by a Turkish notary. Translations made in Germany — even by a certified German court interpreter — are generally not accepted by Turkish courts. This is a step that cannot be cut corners on.

5. Notarised power of attorney (Vekâletname) — since you will be running the entire procedure from outside Turkey, your Turkish lawyer needs a notarised power of attorney authorising them to act on your behalf. This document is issued at a Turkish consulate in your country (for example, in London, Berlin, Amsterdam or Stockholm) and must meet specific formal requirements.

6. Service evidence from the German proceedings — documentation showing that the other parent was properly notified and involved in the German court process: service receipts, hearing summons, proof of delivery. These directly address Condition 3 and should be gathered before filing.

How Long Does It Take — and What Does It Cost?

These are the questions every parent asks first — and rightly so.

To put this in perspective: running a brand-new custody case from scratch before Turkish courts — starting with no German order — would take significantly longer and cost far more. The Tenfiz route uses your existing German judgment as the foundation, making it by far the most efficient path to having your custody rights recognised in Turkey.

Three Problems That Can Derail the Process

1. The Derdestlik Objection — When Turkey Has a Case Already Running

One of the most important — and least discussed — risks in cross-border custody enforcement is what happens when the other parent has already filed their own custody case in Turkey. This is known in Turkish law as the Derdestlik objection (the pending proceedings objection).

If the other parent, anticipating your Tenfiz application, rushes to a Turkish family court and opens a custody or divorce case covering the same subject, they can then argue that the Turkish proceedings should take precedence over your Tenfiz request. The Yargıtay confirmed in a 2023 decision (Case No. 2023/980 K.) that an active Turkish case on the same matter can block or significantly delay enforcement.

In practice, this tactic is used as a delaying strategy: the parent in Turkey hopes that a Turkish court — with a fresh slate, no German judgment to contend with, and potentially applying different standards — will reach a more favourable conclusion. Dealing with this requires a lawyer who can monitor and coordinate both the Turkish proceedings and your Tenfiz application simultaneously — not just one or the other.

2. The Aufenthaltsbestimmungsrecht Problem — A German Concept Turkey Doesn't Have

A typical German custody order grants not only joint custody (gemeinsames Sorgerecht) but also specifies which parent holds the right to determine the child's place of residence — the Aufenthaltsbestimmungsrecht. This right determines where the child primarily lives and is a central part of most German custody arrangements.

The problem: Turkish law has no direct equivalent of the Aufenthaltsbestimmungsrecht. There is no single Turkish legal term that maps cleanly onto this concept. If the Tenfiz application fails to carefully explain what this right means and how it should be interpreted within the Turkish legal framework, the Turkish court may simply ignore it — meaning the most important practical element of your custody order goes unenforced in Turkey.

This is not a rare edge case. It appears repeatedly in Turkish court decisions where Tenfiz applications were partially rejected or narrowed precisely because the legal translation of German custody concepts was incomplete or imprecise. Your Tenfiz petition must bridge this conceptual gap explicitly.

3. Incorrectly Formatted Documents

Turkey's document requirements are strict and unforgiving. An apostille missing from the certificate of finality, a Turkish translation notarised by a German rather than a Turkish notary, or a power of attorney that lacks the correct formal language — any of these can result in your application being rejected at the door before the court even considers its merits.

⚠️ Important: Document errors are the single most common reason Tenfiz applications are delayed or rejected at the initial stage. Every document should be reviewed by your Turkish lawyer before submission. Do not rely on translations or certifications prepared without specific knowledge of Turkish court requirements.

International Child Abduction and the Hague Convention

No guide on cross-border custody between Germany and Turkey would be complete without addressing the risk of international child abduction — a real and serious concern for many families in this situation.

Turkey is a signatory to the 1980 Hague Convention on the Civil Aspects of International Child Abduction (HCCH 1980). So are Germany, the United Kingdom, the Netherlands and most European countries where Turkish diaspora communities live. What this means practically: if one parent — regardless of nationality — permanently relocates a child to Turkey without the consent of the other jointly-custodial parent, this constitutes a wrongful removal under the Convention.

The left-behind parent can apply for the child's return through the relevant Central Authority in their country — the Federal Office of Justice (Bundesamt für Justiz) in Germany, the International Child Abduction Contact Unit in the UK, or equivalent bodies in other countries. Turkey's Central Authority under the Convention is the Ministry of Justice. Turkish courts are legally obligated to order the return of the child unless a narrow set of exceptions applies.

Two important things to understand here. First, the Hague Convention process and the Tenfiz process are completely separate legal tracks — one does not replace or substitute for the other. A Tenfiz order protects your custody rights within the Turkish legal system on an ongoing basis; a Hague return application deals with the immediate emergency of a child wrongfully taken. You may need both, and you may need them at the same time.

Second, the Convention applies regardless of whether your German custody order has already been enforced in Turkey. The relevant question is whether you held a custody right at the time of removal and whether the removal violated that right — not whether Turkey has formally recognised it.

Step-by-Step: Running the Tenfiz Process from Abroad

Here is how the process works in practice — start to finish — without you ever needing to set foot in Turkey.

Step 1 — Grant a power of attorney

Book an appointment at the Turkish consulate nearest to you (in London, Berlin, Amsterdam, Stockholm, Vienna or wherever you are based). Have a comprehensive notarised power of attorney (Vekâletname) issued in favour of your Turkish lawyer. This document must authorise the lawyer to file lawsuits, attend hearings and carry out all procedural acts on your behalf.

Step 2 — Gather and certify your documents

Obtain your German custody judgment with the certificate of finality from the German family court. Have all documents apostilled by the appropriate German authority. Send the documents to a sworn translator registered in Turkey for certified Turkish translation and Turkish notarisation.

Step 3 — Identify the competent Turkish court

The competent court is the Turkish Family Court (Aile Mahkemesi) at the respondent's place of residence in Turkey, as determined by Article 51 of MÖHUK. If the other parent has no fixed Turkish address, the court at their last known place of residence may be used. Your lawyer will confirm the correct venue.

Step 4 — File the Tenfiz petition

Your Turkish lawyer files the petition with all supporting documents. The petition must do more than simply present the German judgment — it must actively explain how the five MÖHUK conditions are satisfied, translate German legal concepts (particularly Aufenthaltsbestimmungsrecht and Umgangsrecht) into their Turkish equivalents, and cite the relevant Yargıtay decisions from 2017, 2023 and 2024 that support enforcement.

Step 5 — Service and hearing

The Turkish court serves the lawsuit on the other party. If the other parent is in Germany or elsewhere in Europe, this involves international service — typically taking 2 to 4 months. Once service is complete, the court schedules one or more hearings at which your lawyer presents the case.

Step 6 — Tenfiz ruling and registration

If the court grants the Tenfiz order, your German custody judgment becomes enforceable in Turkey. Where relevant — for example, if the divorce itself had not yet been registered — the ruling is also reflected in the Turkish civil records. From this point, your joint custody rights can be actively enforced through the Turkish legal system.
