Enforce Foreign Judgment Turkey: The Technical Guide to Tenfiz

You won your case abroad. You hold a final judgment from a court in London, Frankfurt, or New York, and you need to enforce it against a debtor's assets located here in Turkey.

I am a Turkish-qualified lawyer (avukat) admitted to the Kocaeli Bar, and I handle cross-border enforcement across Turkey. When a foreign solicitor or an in-house counsel contacts me, they usually share the same core misconception. They assume a valid German, English, or US judgment can be handed straight to a Turkish bailiff for execution.

It cannot. A foreign judgment is not self-executing in Turkey.

Before we can seize a bank account, liquidate real estate, or attach shares in a Turkish corporation, a Turkish court must first "domesticate" your judgment through a specialized lawsuit called tenfiz. But filing this lawsuit does not mean we litigate your underlying commercial dispute all over again. Turkish law strictly forbids the court from re-hearing the merits of your case.

This page explains exactly how the gateway of recognition and enforcement operates under Turkish private international law. I will show you what the court checks, the strict documentary bundle we must assemble, and how we turn your foreign paper into an executable Turkish judgment.

Is Your Foreign Judgment Enforceable in Turkey?

In broad terms: yes, your judgment is enforceable if it is a final civil or commercial ruling from a proper foreign court, originates from a country that shares reciprocity with Turkey, and does not offend Turkish public policy or due process.

And the reverse fails. If you show up with an interim injunction, a ruling from a jurisdiction with no reciprocity, or a default judgment where the defendant was improperly served, the Turkish court will refuse to enforce it. We must clear a rigid, statutory checklist before any asset recovery begins. Set your expectations accordingly: this is a formal legal procedure, not an administrative rubber stamp.

If your debtor is a corporate entity attempting to evade payment, understanding this framework is critical to recovering a debt from a Turkish company. We often combine the enforcement analysis with preliminary fraud checks, especially when a Turkish company won't pay / suspected scam scenario arises.

Recognition vs Enforcement — Tanıma and Tenfiz

The legal framework governing this process is the Turkish Act on Private International Law and International Civil Procedure (Law No. 5718, known as MÖHUK). Under MÖHUK, you must grasp the strict doctrinal distinction between recognition (tanıma) and enforcement (tenfiz). Choosing the wrong procedural vehicle dooms the filing.

Recognition gives a foreign judgment binding, res judicata effect in Turkey. It means the Turkish legal system treats the matter as settled (kesin hüküm / kesin delil). You file a tanıma lawsuit for status matters—for example, if you need a foreign divorce decree or a paternity ruling recognized to update the Turkish civil registry.

Enforcement (tenfiz) encompasses recognition but goes one massive step further: it lets you execute. When you hold a money judgment and need the coercive power of the Turkish state to seize assets, you need a tenfiz decree.

Crucially, the statutory conditions for these two actions are not identical. Reciprocity is a mandatory requirement for enforcement, but MÖHUK Article 58 explicitly waives the reciprocity requirement for recognition.

The Conditions a Turkish Court Checks

When I file a tenfiz lawsuit for you, the Turkish judge evaluates your foreign judgment against a closed, rigid checklist set out in MÖHUK Articles 50 and 54. The court does not care about the underlying fairness of your commercial dispute. It only checks the following conditions.

1. Reciprocity (Mütekabiliyet)

I look at this first. It is the make-or-break condition. A Turkish court will only enforce your judgment if your country would enforce a comparable Turkish judgment. Under Turkish law, reciprocity exists on three bases:

• Treaty-Based: A bilateral or multilateral treaty exists between Turkey and the issuing country. For instance, Turkey has long-standing treaties covering mutual enforcement with states like Italy, Montenegro, and Serbia.
• Statutory Basis: The internal law of the issuing country explicitly allows the enforcement of Turkish judgments without requiring a treaty.
• De Facto Reciprocity: Shown by actual, current court practice. If the foreign country's courts routinely enforce Turkish judgments, we submit those foreign court precedents to the Turkish judge to prove reciprocity exists in fact.

Whether a given country has reciprocity with Turkey is a real, checkable question. I never assert it blindly. While major commercial jurisdictions like Germany and the United Kingdom generally enjoy de facto reciprocity, the position can shift, and in federal systems like the United States, we must often prove reciprocity on a state-by-state basis. We assess this case by case before you spend a single lira on court fees.

2. Finality (Kesinleşme)

Your judgment must be final, binding, and unappealable in its home country — this is a precondition under MÖHUK Article 50 (which defines an enforceable foreign ilam as one that is final under the law of the state that issued it), distinct from the four Article 54 conditions. MÖHUK demands proof of this. You cannot enforce an interim injunction, a preliminary asset freeze, or a judgment that the debtor is actively appealing in your local appellate courts. We prove finality using a specific annotation from your court, known in Turkish practice as the kesinleşme şerhi.

3. Public Policy (Kamu Düzeni)

Under MÖHUK 54/c, the court will refuse enforcement if your judgment plainly offends Turkish public policy. Turkish courts apply a narrow "international public policy" standard here. They do not reject a judgment just because Turkish substantive law would have yielded a different result. They reject judgments that violate fundamental moral standards or core constitutional principles—for example, enforcing a gambling debt or awarding massive, arbitrary punitive damages that bear no relation to actual economic loss.

4. Defence Rights and Proper Service

This is the debtor's primary weapon. Under MÖHUK 54/ç, a debtor can block enforcement by proving they were not properly summoned, not properly represented, or not given a genuine chance to defend themselves.

I see this constantly with foreign default judgments. A default judgment is entirely valid in Turkey, provided you served the defendant strictly by the book. If you bypassed the Hague Service Convention and simply mailed a summons to an Istanbul address via DHL, the Turkish court will likely deem the service defective, ruling that the debtor's defence rights were violated.

5. Exclusive Jurisdiction

Your case must not fall within the exclusive jurisdiction of the Turkish courts. You cannot, for example, bring a German judgment attempting to transfer the title of real estate located in Turkey. Cases concerning rights in rem over Turkish immovable property belong exclusively to Turkish judges.

What a Turkish Court Will Not Do

I get asked this by foreign lawyers constantly: Will the Turkish judge demand to see our commercial contracts and re-weigh the evidence?

Absolutely not. Turkish private international law applies a strict prohibition on reviewing the merits, known doctrinally as the prohibition on révision au fond (revision au fond yasağı).

The Turkish judge operates strictly as a gatekeeper. The court audits your judgment against the MÖHUK conditions listed above. It does not reopen the underlying dispute to decide who was right or wrong in the original transaction. If your judgment passes the statutory tests, the judge is legally obligated to enforce it. This is a genuine comfort to creditors who dread the prospect of litigating the same complex commercial dispute twice.

The Tenfiz Lawsuit — How It Actually Runs

You do not simply register your judgment at a government desk. Enforcement requires filing an adversarial lawsuit (tenfiz davası).

As a general matter, the proper forum is the Civil Court of First Instance (Asliye Hukuk Mahkemesi) located where the debtor is domiciled in Turkey. If the underlying dispute is inherently commercial, we file in the specialized Commercial Court of First Instance (Asliye Ticaret Mahkemesi).

The procedure runs under the simplified trial rules (basit yargılama usulü), meaning the exchange of petitions is streamlined to move faster than a standard trial. We serve the debtor, and they have the right to appear and defend themselves. But remember, they are legally restricted to raising the limited statutory defences found in MÖHUK Article 54 (e.g., "I was never properly served" or "This violates public policy"). They cannot argue "I don't actually owe the money."

There is one major procedural hurdle foreign plaintiffs must clear: security for costs (teminat). Under MÖHUK Article 48, foreign individuals and legal entities filing a lawsuit in Turkey must deposit a security bond to cover potential court fees and the defendant's damages if the case fails. But exemptions exist. If your country is a signatory to the 1954 Hague Convention on Civil Procedure, or if bilateral agreements establish reciprocal exemptions, I will petition the judge to waive this security requirement entirely.

When the court approves the enforcement, it issues a Turkish judgment (ilam) that mirrors your foreign ruling. You now have an executable Turkish court order.

The Documents You Need

Getting the physical document bundle right is half the battle. A defective set stalls the case immediately. Because of my apostille and translation practice, I am exceptionally strict about this. To file, I need:

• The Authenticated Judgment: The original physical document, or a copy definitively certified by the foreign court that issued it.
• The Finality Annotation: Official proof from the foreign court that the judgment is final, binding, and no longer subject to ordinary appeal.
• Apostille or Legalisation: Both the judgment and the finality proof must bear an Apostille stamp under the 1961 Hague Convention. If your country is not a party to the Apostille convention, the documents must go through the longer chain of consular legalisation ending at the Turkish consulate in your jurisdiction.
• Sworn Translations: Every page of the authenticated bundle must be translated into Turkish by a sworn translator and then notarized by a Turkish Notary Public.

Arbitral Awards Are a Different Route

We must draw a hard line here. A foreign arbitration award (such as an award from the ICC, LCIA, or an ad hoc tribunal) is not a foreign court judgment.

Foreign arbitral awards are enforced through a completely separate legal track under the 1958 New York Convention, to which Turkey is a party. The local procedural steps in Turkey rely on MÖHUK Articles 60–63, but the actual grounds for a judge to refuse enforcement are strictly governed by Article V of the New York Convention.

If you hold an arbitral award rather than a state court judgment, the documentary requirements and the legal analysis differ slightly. I handle both, but we must classify your asset correctly from day one.

After Tenfiz — Now You Can Actually Collect

The tenfiz lawsuit secures your legal right to collect. Once the judge hands down the final Turkish ilam, we transition immediately into the aggressive phase.

Your domesticated judgment now holds the exact same legal weight as if you had sued the debtor in Istanbul and won. I take that ilam to the Turkish Execution Office (İcra Dairesi) and launch formal enforcement proceedings (icra takibi). This is where we freeze bank accounts, attach real estate through the land registry, seize vehicles, and go after corporate shares.

For the precise mechanics of how we trace and liquidate those assets, read my deep-dive on seizing a Turkish debtor's assets, or review the broader strategy on my debt collection in Turkey hub.

How I Run This for a Creditor Abroad

You do not have to fly to Turkey to enforce your judgment. I run this entire procedure on the ground while you remain in your home jurisdiction.

We act through a specialized, notarised, and apostilled Power of Attorney (vekaletname). I review your documents, map the reciprocity status of your home country, manage the sworn Turkish translations, file the lawsuit, and litigate the hearings. I communicate in plain English, ensuring that a non-Turkish-speaking client knows exactly what is happening in the courtroom and at the bailiff's office.

If you are a foreign lawyer seeking local counsel, I accept referrals, work alongside you, and aggressively protect your primary relationship with your client.

What It Costs and How Long It Takes

I prefer to be honest and hedged. The real drivers of time and cost are whether your country has unassailable reciprocity with Turkey, and how hard your debtor fights back.

If you bring me a clean, properly apostilled judgment from a jurisdiction with rock-solid reciprocity (like Germany or the UK), and the debtor was served perfectly and raises no substantive defence, the first-instance court can conclude the tenfiz case in roughly 6 to 12 months.

But if the debtor contests the validity of the foreign service, argues a public policy violation, or appeals the Turkish judge's decision up to the Court of Cassation (Yargıtay), the timeline extends significantly. Costs include the statutory court filing fees, the notary and translation expenses, and my legal fees. Execution office fees apply downstream, once we actually begin seizing assets.

I never promise guaranteed enforcement. A reciprocity gap or a fatal flaw in your original service of process can defeat the action, and I will tell you that plainly before we begin.

Ready to Enforce Your Judgment?

If you hold a final judgment against a debtor with assets in Turkey, send me a copy of the judgment and the finality confirmation. I will review the documents and tell you honestly whether it is enforceable in Turkey under MÖHUK, what the specific risks are, and exactly how we proceed.
