Service and Due Process Objections in Turkish Tenfiz Proceedings

A defendant against whom enforcement of a foreign judgment is sought in Turkiye may object that they were not properly summoned or represented in the foreign proceedings, and were consequently deprived of the ability to defend themselves. If the Turkish court finds this objection well-founded, enforcement is refused regardless of the judgment's substantive merits.

Due process protection in tenfiz proceedings exists to prevent a foreign judgment obtained without genuine notice or a fair opportunity to defend from being given effect in Türkiye. This is not a review of whether the foreign court's decision was correct, but of whether the defendant had a real chance to participate in the proceedings that led to it.

Article 54 of Law No. 5718 on Private International Law and International Civil Procedure (MOHUK) provides that enforcement will be refused where the person against whom enforcement is sought was not duly summoned or represented before the foreign court, or was otherwise deprived of the opportunity to defend themselves, in a manner contrary to the fundamental principles of Turkish procedural public policy. This ground operates independently of reciprocity, jurisdiction, and substantive public policy, which are examined separately.

Turkish courts assess whether the summons abroad reached the defendant in a manner that genuinely allowed a defence, looking at whether the method of service complied with the procedural rules of the foreign forum and whether it was realistically capable of coming to the defendant's attention. Courts have refused enforcement where notification was purely formal or where the defendant was unaware of the proceedings until after judgment, while upholding enforcement where the defendant was shown to have had actual knowledge and a genuine opportunity to appear, even if they chose not to.

There is ongoing debate over how much weight should be given to a defendant's actual awareness of foreign proceedings versus strict formal compliance with the service rules of the foreign forum. Some commentators argue that any procedural defect abroad should be enough to refuse enforcement, while others favour a functional test asking whether the defendant, in substance, had a fair chance to respond. Cross-border service through international conventions and its interaction with domestic Turkish notification rules also generates disagreement, particularly where the defendant is a company represented by a local agent abroad.

A defendant relying on this objection must show, with concrete evidence, how notification failed or fell short: wrong address, defective method of service, absence of translation where required, or representation without proper authority. General assertions that proceedings abroad were "unfair" without supporting facts rarely succeed.

The objection is raised as a defence within the tenfiz proceedings themselves, following the general timeline for submitting a response and evidence in Turkish civil procedure. Delay in raising the objection, or a failure to raise it in the first responsive submission, can weaken the position taken.

The competent Turkish civil court of first instance handling the tenfiz action rules on this objection as part of its overall examination of the statutory conditions for enforcement.

Relevant evidence includes the foreign court file showing how and when notification was attempted, proof of the defendant's actual address at the relevant time, any correspondence demonstrating lack of knowledge of the proceedings, and expert or documentary evidence on the foreign procedural rules that were supposed to apply.

Defendants sometimes assume that simply not having appeared abroad is enough to block enforcement in Türkiye; it is not, if service was in fact proper and effective. Conversely, claimants sometimes underestimate the objection and fail to prepare a complete record of service, leaving gaps that a defendant can exploit. Confusing this ground with a general appeal against the substance of the foreign judgment is another recurring error, since Turkish courts do not re-examine the merits.

Whether representing the party seeking enforcement or the party resisting it, the service record from the foreign proceedings deserves early and careful attention. A complete file documenting how and when the defendant was notified is often the single most useful piece of evidence in a tenfiz case involving this objection.
