Can a Foreign Default Judgment Be Enforced in Turkey? Service, Defence Rights and MÖHUK Article 54

1. Default judgment does not mean defective judgment

Many legal systems allow a court to decide a case when a properly notified defendant fails to appear or respond. Such a judgment can be fully valid and final in the state of origin. Turkish private international law does not create a blanket rule rejecting every default decision.

The enforcement question focuses on procedural fairness as defined in Article 54. If the defendant was legally notified and had a genuine opportunity to defend, voluntary silence does not necessarily prevent tenfiz.

Therefore, both creditor and debtor should obtain the foreign service file before assuming the outcome.

2. Article 54(1)(ç) contains a specific defence-right protection

The statute addresses three related situations: the person was not summoned properly under the law of the foreign state, was not represented in that court, or the judgment was entered in absence/default in a way contrary to that foreign law.

The Turkish court does not ask whether Turkish domestic service rules were followed in the foreign case. It asks whether the foreign procedure applicable to that case was respected, together with any binding international service convention.

The defendant must rely on the Article 54 ground in the Turkish enforcement proceeding.

3. Proper summons is assessed under the law of the issuing state

A Turkish defendant sued abroad should not assume that service is invalid simply because the foreign system uses a procedure different from Turkish court service. The law of the origin state determines its domestic service requirements, while treaties can impose additional cross-border rules.

Foreign procedural legislation, court rules and official service certificates can therefore be necessary evidence in Türkiye.

MÖHUK Article 2 allows the Turkish court to determine foreign law ex officio and request party assistance.

4. The Hague Service Convention can be decisive when papers were transmitted internationally

Where both Türkiye and the issuing state are parties to the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters, service should be analysed under that treaty and any declarations/reservations made by the states.

Central-authority certificates, translations and method of service can become central to the Article 54 review.

A claimant should not rely only on a foreign docket notation saying “served” when the cross-border transmission record raises a treaty issue.

5. Service to an obsolete address can create a serious enforcement defence

A foreign claimant may serve an old Turkish address even though the defendant moved years earlier and the claimant knew or should have known the current address. Whether that service is legally valid depends on the foreign law, treaty and facts.

The defendant should prove the move date, registered address and any evidence that the claimant knew the correct location.

A mere assertion that “I never personally saw the document” is not enough where valid substituted service occurred under the applicable law.

6. Electronic service must have a legal basis

Some jurisdictions permit email, online portal or electronic court-account service. Others require court permission before electronic service on a foreign defendant.

The Turkish court should examine whether the foreign procedure treated the electronic method as valid and whether any international service restriction applies.

An ordinary lawyer-to-party email is not automatically formal service merely because it attached the complaint.

7. Substituted service can be valid if authorised properly

Foreign courts sometimes allow service by publication, post, relatives, registered agent or other substituted methods after ordinary service fails. A default judgment based on substituted service can still be enforceable if the method complied with the foreign law and applicable treaty framework.

The underlying order permitting substituted service should be obtained. The court may need to know what attempts were made first and why the alternative method was authorised.

Service designed only to create technical compliance without a reasonable notice opportunity can also raise broader public-order concerns in an extreme case.

8. Actual representation can cure some notice concerns but not every defect

If a lawyer appeared for the defendant, filed submissions and participated in the foreign proceedings, it becomes difficult to argue that the defendant had no opportunity to defend simply because an earlier service step was imperfect.

However, the representative must have had valid authority and sufficient opportunity to present the case under the foreign procedure.

The Turkish court should examine the full foreign docket rather than one isolated service document.

9. Deliberate nonappearance is different from lack of notice

A defendant can receive proper summons and choose not to respond because it believes the foreign court lacks jurisdiction, the claim is weak or litigation is too expensive. That strategic choice does not automatically block Turkish enforcement later.

If the defendant wished to challenge foreign jurisdiction, the appropriate foreign procedural remedy may have been available at the time. Article 54’s separate exorbitant-jurisdiction ground can still be relevant in Türkiye if its conditions are met.

Ignoring litigation should never be treated as a safe enforcement strategy.

10. Language can affect fairness but not every untranslated document defeats enforcement

International service treaties and foreign procedural law determine when translations are required. A Turkish defendant receiving foreign papers in a language it does not understand can have a legitimate procedural argument where the applicable rules required translation.

On the other hand, a bilingual commercial company that contracted in English and received legally valid English proceedings cannot automatically rely on language as a defence.

The exact documents, treaty declarations and procedural rights must be checked.

11. Notice must provide the legally required opportunity to prepare a defence

Service performed technically before a hearing can still be defective if the foreign law required a minimum response period that was not respected. The defendant should obtain the foreign rules on response time and the docket dates.

Emergency proceedings and interim measures can have shorter timelines, but a final merits judgment requires the procedural safeguards of the issuing system.

The Turkish court should focus on whether the defendant was deprived of the defence opportunity protected by Article 54.

12. The defendant must invoke the defence-right ground in the Turkish case

Article 54(1)(ç) is framed as a ground relied upon by the person against whom enforcement is sought. A defendant served with the Turkish tenfiz petition should raise the specific service/default objection in the response.

Generic statements that “the foreign case was unfair” are less useful than a documented explanation of the summons defect and the foreign law violated.

Procedural deadlines in the Turkish case should be treated as urgent.

13. A judgment creditor should prepare the service record before filing

If the foreign judgment was entered by default, the creditor should anticipate the Article 54 objection. Obtain the complaint, summons, official service certificate, returned delivery record, court order on substitute service and any evidence that the defendant participated.

Have the critical documents authenticated and translated where needed.

A tenfiz petition built only around the judgment and finality certificate can become vulnerable if the defendant raises a well-documented service challenge.

14. A debtor should prove more than nonparticipation

The debtor should identify the precise defect: wrong address, no treaty-compliant service, no required translation, unauthorised substitute service, invalid representation or insufficient procedural time.

Evidence can include passport/travel history, address records, email correspondence and foreign procedural materials.

A defendant who actually received the papers but chose not to act should receive advice based on that reality rather than build a false service narrative.

15. Proper service does not replace the finality requirement

Even a procedurally flawless default judgment must satisfy Article 50 finality. The creditor needs an authenticated finality certificate or equivalent proof from the issuing state.

Some systems permit a default judgment to be set aside within a special period after actual notice. The relationship between that remedy and finality should be examined under foreign law.

A pending set-aside application can affect the Turkish enforcement strategy.

16. Public order is separate from the specific service defence

Severe denial of due process can also raise Article 54 public-order issues, but the specific service/default clause should normally be addressed first where it directly covers the problem.

Public order has a high threshold and should not be used to duplicate every procedural objection.

The Turkish court should preserve the distinction between statutory defence-right control and fundamental public-order control.

17. Default judgments can also face the same defence-right issue in recognition

Article 58 imports the relevant Article 54 conditions into recognition, excluding only reciprocity. Therefore, a foreign default judgment sought merely as res judicata or evidence can still face service/defence objections.

The absence of a money-enforcement request does not eliminate due-process scrutiny.

The applicant should preserve the service record even for recognition-only cases.

Conclusion

A foreign default judgment can be enforced in Türkiye when the defendant was properly summoned and given the procedural opportunity required by the law of the issuing state. Default itself is not a bar. The decisive evidence is the foreign service and procedural record. Creditors should obtain it before filing; defendants should identify and prove a specific defect rather than rely on the fact of nonappearance alone. Finality, jurisdiction, public order and other Article 54 conditions remain separate requirements.
