Enforcing a Switzerland Court Judgment in Turkey

Enforcing a Switzerland court judgment in Turkey is achievable but requires a dedicated recognition and enforcement proceeding before a Turkish civil court. Turkey and Switzerland have not concluded a bilateral treaty on the mutual recognition of judgments, which means the process is governed entirely by Turkish domestic law - specifically the International Private and Procedural Law (MÖHUK, Law No. 5718). This guide explains the full procedure, the documents you need, realistic timelines and costs, the defences a Turkish debtor can raise, and the strategic choices that improve your chances of success.

Turkey's primary statute for recognising and enforcing foreign judgments is MÖHUK (Law No. 5718 on International Private and Procedural Law). Because no bilateral enforcement treaty exists between Switzerland and Turkey, MÖHUK applies exclusively. The law sets out a reciprocity requirement and a series of substantive conditions that a foreign judgment must satisfy before a Turkish court will declare it enforceable.

Reciprocity under MÖHUK is interpreted broadly by Turkish courts. It does not require a formal treaty. Courts examine whether Swiss courts would, in practice, recognise a Turkish judgment under comparable conditions. Switzerland's Federal Act on Private International Law (IPRG) and its cantonal procedural rules do permit recognition of foreign judgments under certain conditions, and Turkish courts have generally accepted this as sufficient evidence of de facto reciprocity. In practice, reciprocity is rarely the decisive obstacle for Swiss judgments, but it must be formally pleaded and evidenced.

The competent court in Turkey is the civil court of first instance (Asliye Hukuk Mahkemesi) at the place of the debtor's domicile or, if the debtor has no domicile in Turkey, at the location of the assets to be seized. Jurisdiction must be established carefully at the outset, because filing in the wrong court causes delay and additional cost.

MÖHUK Article 50 sets out the conditions for recognition and enforcement. Each condition is examined independently, and failure on any single point is fatal to the application.

The judgment must be final and binding (kesinleşmiş) under Swiss law. A judgment that is still subject to an ordinary appeal in Switzerland cannot be enforced in Turkey. You must obtain a certificate of finality from the competent Swiss court or cantonal authority confirming that the ordinary appeal period has expired or that all appeals have been exhausted.

The subject matter of the dispute must not fall within the exclusive jurisdiction of Turkish courts. Turkish law reserves exclusive jurisdiction over, among other things, disputes concerning immovable property located in Turkey and certain family-law matters. A Swiss money judgment arising from a commercial contract will generally not trigger this exclusion, but judgments touching on Turkish real estate or Turkish corporate registration matters require careful analysis before filing.

The judgment must not violate Turkish public policy (kamu düzeni). This is the most frequently invoked defence and the most fact-sensitive. Turkish courts have refused enforcement where a foreign judgment awarded punitive damages at a level considered disproportionate, where procedural due process was found to be lacking, or where the underlying claim conflicted with mandatory Turkish rules. A Swiss judgment for compensatory damages on a standard commercial claim is unlikely to fail this test, but the analysis should be done in advance.

The defendant must have been duly served under Swiss procedural law and must have had a genuine opportunity to defend. If service was defective - for example, if a Turkish-domiciled defendant was served only by publication without actual notice - the Turkish court will refuse enforcement. Collect the full service record from the Swiss proceedings.

The judgment must not conflict with a prior Turkish court judgment or a prior foreign judgment already recognised in Turkey on the same dispute between the same parties.

Assembling the correct document package before filing saves weeks of back-and-forth with the Turkish court. The core documents are:

• The original Swiss judgment or a certified copy, issued by the competent Swiss court.
• A certificate confirming that the judgment is final and enforceable (Rechtskraftbescheinigung in German-language cantons, or equivalent in French or Italian cantons).
• Proof of proper service on the defendant during the Swiss proceedings.
• A sworn Turkish translation of all documents, prepared by a certified translator and notarised in Turkey or apostilled abroad.
• An apostille affixed to the Swiss court documents under the Hague Apostille Convention, to which both Switzerland and Turkey are parties. This simplifies authentication considerably compared to the older legalisation chain.

A common mistake is to submit translations certified only by a Swiss notary. Turkish courts require translations made by a sworn translator registered in Turkey, or translations apostilled in the country of origin. Confirm the translation route with Turkish counsel before commissioning the work.

If the judgment includes interest, clarify whether the interest rate and calculation method are stated in the judgment itself. Turkish enforcement courts will enforce interest as awarded; they will not recalculate it under Turkish law unless the judgment is silent.

The proceeding to enforce a Switzerland judgment in Turkey is called a tanıma ve tenfiz davası - a recognition and enforcement action. It is a civil lawsuit, not an administrative procedure, and it follows the standard Turkish Code of Civil Procedure (HMK, Law No. 6100).

The claimant (judgment creditor) files a petition with the competent Asliye Hukuk Mahkemesi. The petition must identify the parties, describe the Swiss judgment, attach the authenticated documents, and formally request recognition and enforcement. The court serves the petition on the defendant, who has the right to file a written defence.

The scope of review is limited. The Turkish court does not re-examine the merits of the underlying dispute. It reviews only whether the MÖHUK conditions are satisfied. This is sometimes called révision au fond interdite - the prohibition on reviewing the substance of the foreign judgment. In practice, hearings focus on the documentary record and on any defences the debtor raises.

Typical timelines run from six to eighteen months for a first-instance decision, depending on the court's docket, the complexity of the defences raised, and whether expert evidence is needed on Swiss law. Courts in Istanbul and Ankara tend to have heavier dockets than courts in smaller cities. If the debtor appeals to the Regional Court of Appeal (Bölge Adliye Mahkemesi) and then to the Court of Cassation (Yargıtay), the total process can extend to three years or more.

Once the Turkish court issues a recognition and enforcement judgment (tenfiz kararı), the Swiss judgment becomes enforceable in Turkey as if it were a Turkish judgment. The creditor then proceeds through the Turkish Enforcement and Bankruptcy Offices (İcra Müdürlükleri) to seize assets, garnish bank accounts, or attach receivables.

Understanding the defences available to the debtor allows the creditor to anticipate and counter them in the initial petition.

The most common defence is public policy (kamu düzeni). Debtors argue that enforcement would violate fundamental Turkish legal principles. This defence succeeds most often when the Swiss judgment contains punitive or exemplary damages, when the underlying contract contained terms prohibited under Turkish mandatory law, or when the Swiss court applied a choice-of-law clause that bypassed Turkish consumer or employment protections. For straightforward commercial judgments between sophisticated parties, this defence is difficult to sustain.

Lack of proper service is the second most common defence. If the debtor can show that it did not receive actual notice of the Swiss proceedings in time to prepare a defence, the Turkish court will refuse enforcement. Creditors should pre-empt this by including the complete Swiss service record in the initial filing.

Jurisdictional objections arise when the debtor argues that the Swiss court lacked jurisdiction under Turkish conflict-of-laws rules. MÖHUK Article 50(1)(b) requires that the Swiss court had jurisdiction according to criteria that Turkish law would recognise. If the Swiss court's jurisdiction rested solely on a forum-selection clause that Turkish law would not honour, or on a jurisdictional ground that Turkish rules do not accept, the enforcement can be refused.

Res judicata is raised when a Turkish court has already decided the same dispute or when a prior foreign judgment on the same matter has already been recognised in Turkey. This defence requires the debtor to produce the earlier Turkish or recognised foreign judgment.

A non-obvious requirement is that the debtor may not raise defences going to the merits - for example, arguing that the Swiss court reached the wrong factual conclusion. The Turkish court will reject such arguments as outside the scope of the enforcement review.

Enforcement costs in Turkey fall into three categories: court fees, legal fees, and enforcement execution costs.

Court fees for the recognition and enforcement action are calculated as a proportion of the claim value under the Turkish Fee Schedule (Harçlar Kanunu). For significant commercial judgments, these fees can reach a meaningful sum, though they remain a fraction of the judgment amount. Budget for court fees at a low-to-moderate percentage of the claim.

Legal fees depend on the complexity of the case, the number of hearings, and whether the matter is appealed. For a straightforward recognition action without contested defences, professional fees typically start from the low thousands of euros equivalent. Contested proceedings with expert evidence on Swiss law and multiple appeal stages can cost several times that amount.

Enforcement execution costs - the fees charged by the İcra Müdürlüğü for asset searches, seizure orders, and auction proceedings - are additional and are generally recoverable from the debtor if enforcement succeeds.

Practical scenario one: a Swiss-based supplier obtains a judgment against a Turkish importer for unpaid invoices. The judgment is final, service was properly documented, and the claim is purely for the invoice amount plus contractual interest. This is the most straightforward enforcement scenario. The creditor files in the court at the debtor's registered address in Istanbul, attaches apostilled documents with certified Turkish translations, and can reasonably expect a first-instance decision within nine to twelve months if the debtor does not contest vigorously.

Practical scenario two: a Swiss private equity fund obtains a judgment against a Turkish individual guarantor for a defaulted loan. The individual is domiciled in Ankara but has assets in multiple cities. The fund must decide whether to file at the debtor's domicile or at the location of the most valuable assets. Filing at domicile is generally safer for jurisdiction, but the fund should simultaneously prepare asset-tracing steps so that enforcement execution can begin immediately after the tenfiz kararı is issued.

Many creditors underestimate the importance of asset tracing before or during the recognition proceeding. Turkish enforcement law allows precautionary attachment (ihtiyati haciz) of assets even before a final enforcement judgment, provided the creditor can show a credible claim and risk of dissipation. Applying for ihtiyati haciz in parallel with the recognition action is a powerful tool that prevents the debtor from moving assets during the litigation.

What happens if the Swiss judgment includes punitive damages - will a Turkish court enforce them?

Turkish courts apply a strict public policy filter to foreign judgments that include punitive or exemplary damages. Where the punitive element is clearly separable from the compensatory award, a Turkish court may enforce the compensatory portion while refusing the punitive portion. Where the two are inseparable, the court may refuse enforcement of the entire judgment. Creditors holding Swiss judgments with a punitive component should obtain a legal opinion on severability before filing. In some cases, it is strategically better to seek a new Swiss judgment limited to compensatory relief than to risk full refusal in Turkey.

How long does the full enforcement process take, and what drives the timeline?

A first-instance recognition decision typically takes between six and eighteen months from the date of filing. The main variables are the court's docket load, whether the debtor contests the action, and whether expert evidence on Swiss law is required. If the debtor appeals to the Regional Court of Appeal and then to the Court of Cassation, the total process can extend to three years or more. Creditors can shorten the effective timeline by applying for precautionary attachment (ihtiyati haciz) at the outset, which freezes assets while the recognition proceeding runs. Thorough preparation of the document package before filing also reduces adjournments caused by missing or incorrectly authenticated documents.

Is it possible to enforce a Swiss arbitral award in Turkey instead of a court judgment, and is the process different?

Yes, and the process is meaningfully different. Swiss arbitral awards are enforced in Turkey under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, to which both Switzerland and Turkey are parties. The New York Convention provides a more standardised and generally more creditor-friendly framework than MÖHUK, with a narrower list of grounds for refusal. If a creditor holds both a Swiss arbitral award and a Swiss court judgment confirming that award, enforcing the arbitral award under the New York Convention is usually the preferred route. The procedural steps - filing a petition, serving the debtor, limited merits review - are similar, but the substantive defences available to the debtor are more constrained under the Convention than under MÖHUK.

Enforcing a Swiss court judgment in Turkey is a structured, multi-stage process governed by MÖHUK and Turkish civil procedure. Success depends on satisfying the statutory conditions, assembling correctly authenticated documents, and anticipating the defences a Turkish debtor is likely to raise. With careful preparation, creditors holding straightforward commercial judgments can obtain a Turkish enforcement order and proceed to asset seizure within a realistic timeframe.
