Reciprocity for Enforcing Foreign Judgments in Turkey: MÖHUK Article 54, Treaties, Foreign Law and De Facto Practice

1. Reciprocity is a condition of coercive enforcement, not recognition of truth

Tenfiz permits a foreign judgment to use Turkish state enforcement power against assets. Article 54 therefore requires a reciprocal legal possibility that Turkish judgments can receive enforcement in the originating state.

The rule does not mean the foreign state must use exactly the same procedure or identical statutory wording. It requires a meaningful enforcement possibility through treaty, legislation or actual judicial practice.

This explains why recognition under Article 58 does not need reciprocity: recognition gives res judicata/evidence effect but does not itself use Turkish enforcement power.

2. Treaty, statute and de facto practice are alternative bases

Article 54(a) is drafted disjunctively. The applicant can satisfy reciprocity through one of the recognised routes. A state does not need a bilateral treaty with Türkiye if its domestic law already allows Turkish judgments to be enforced.

Likewise, an absence of explicit legislation does not necessarily end the inquiry if courts have an established practice of enforcing Turkish judgments.

The application should identify the strongest available basis rather than vaguely asserting “reciprocity exists.”

3. Treaty reciprocity is usually the easiest to document

A bilateral judicial-assistance or judgment-enforcement treaty can directly establish the mutual legal framework. Multilateral conventions can also apply within their subject matter.

The applicant should produce or cite the official treaty text, confirm that it is in force for both states and verify that the foreign judgment falls within its material scope.

A treaty on service of documents does not automatically constitute a judgment-enforcement treaty.

4. A treaty can contain exclusions that matter

Judicial-cooperation instruments sometimes exclude bankruptcy, family status, succession, tax, administrative matters or other categories. A treaty’s existence alone is therefore insufficient.

The judgment type should be compared with the treaty’s scope and definitions. A commercial money judgment can fall within a treaty while a family maintenance order follows another instrument.

Reservations and later protocols should also be checked.

5. Foreign legislation can create reciprocity without a treaty

Many states have general foreign-judgment statutes that permit enforcement if jurisdiction, finality, service and public-policy conditions are met. If those statutes are available to Turkish judgments, Article 54(a) can be satisfied.

The foreign law does not need to refer to “Türkiye” by name if it generally permits enforcement of foreign judgments without excluding Turkish courts.

However, a foreign statute that categorically excludes Turkish judgments or requires an impossible treaty can prevent statutory reciprocity.

6. Foreign law should be proved through reliable current sources

MÖHUK Article 2 requires Turkish courts to determine foreign law ex officio and allows them to seek party assistance. The applicant should nevertheless make the reciprocity issue easy to verify.

Official foreign legislation, ministry guidance, translated statutes, expert legal opinions and foreign court decisions can all help. The material should show the current law, not an obsolete provision.

Unverified law-firm blog posts should not be the sole source for a mandatory enforcement condition.

7. De facto reciprocity is based on real foreign enforcement practice

Article 54(a) expressly recognises factual practice. This is important where the foreign jurisdiction has no special treaty with Türkiye and its legislation is uncertain or judge-made.

Evidence that courts in that state have previously recognised and enforced Turkish judgments can establish the practical possibility required by MÖHUK.

The decisions should be comparable and sufficiently current to show an actual practice rather than an isolated historical exception.

8. Foreign judgments enforcing Turkish decisions are strong evidence

A certified or reliable copy of a foreign court decision granting enforcement to a Turkish judgment can be highly persuasive. Multiple decisions from appellate courts strengthen the position.

The applicant should explain the foreign enforcement standard and whether the case involved the same type of Turkish judgment.

Where foreign decisions are not publicly available, an expert opinion can summarise established practice with citations.

9. Reciprocity can change when foreign law or practice changes

A country that once enforced Turkish judgments can amend its law, join a convention or develop contrary judicial precedent. The reciprocity inquiry should therefore use current information as of the Turkish enforcement proceedings.

An old Turkish appellate decision about reciprocity with a particular country should not automatically be assumed current decades later.

Legal research should verify whether the foreign enforcement environment has materially changed.

10. Different procedural conditions do not automatically destroy reciprocity

The foreign state can require finality, proper jurisdiction, service, public policy and other conditions that differ from Turkish MÖHUK. Reciprocity does not necessarily mean identical enforcement tests.

The key question is whether Turkish judgments can meaningfully be enforced. A reasonable set of general conditions can still support reciprocity.

If the foreign system makes Turkish judgments practically unenforceable through discriminatory or impossible requirements, the analysis changes.

11. Reciprocity concerns judgments, not nationality treatment

Article 54(a) does not ask whether Turkish citizens can buy property, obtain visas or receive equivalent civil rights in the foreign state. Those are different reciprocity concepts used in other areas of law.

The tenfiz question is specifically whether Turkish court judgments can receive enforcement in the state that issued the judgment now presented to Türkiye.

Do not substitute diplomatic or immigration reciprocity for judgment reciprocity.

12. Recognition deliberately removes the reciprocity requirement

Article 58 applies the enforcement conditions to recognition but expressly excludes Article 54(a). A final foreign judgment can therefore be recognised as res judicata or conclusive evidence even when reciprocity for coercive enforcement is not established.

This distinction can be strategically important. A party may need only to prevent relitigation or update legal status rather than seize assets.

Our recognition versus enforcement guide explains when each procedure is needed.

13. Foreign arbitral awards use a different reciprocity framework

Foreign arbitral awards are commonly enforced under the 1958 New York Convention, which has its own treaty architecture and reservations. MÖHUK Articles 60–63 can also be relevant.

Do not apply Article 54(a) judgment reciprocity mechanically to arbitral awards.

The origin of the award, seat of arbitration and convention status must be analysed separately.

14. Applicants should not wait for the court to research reciprocity from scratch

Although foreign law is determined ex officio, a professional tenfiz file should identify the reciprocity basis and submit supporting material. This reduces delay and uncertainty.

The defendant can challenge the applicant’s material with updated foreign law or evidence that Turkish judgments are not actually enforceable there.

The issue is legal and documentary rather than dependent on witness testimony.

15. Ministry and judicial cooperation sources can assist

Turkish Ministry of Justice materials, official treaty databases and foreign ministries of justice can provide authoritative information on bilateral agreements and foreign enforcement laws.

Where a court requests information through official channels, the process can take time. Filing with reliable sources can help focus the inquiry.

Translations should identify the source and effective date of the foreign law.

16. Check reciprocity before spending heavily on authentication and translation

Foreign judgments can run hundreds of pages. Before translating extensive files, first determine whether reciprocity is likely to satisfy Article 54(a).

If reciprocity exists, prepare the complete Article 53 documents and other Article 54 conditions. If it does not, consider whether recognition alone is sufficient for the client’s objective or whether a fresh Turkish claim is legally possible.

The correct strategy depends on limitation, res judicata and the nature of the underlying right.

17. Absence of reciprocity can block tenfiz but does not automatically erase the foreign judgment

A foreign judgment that cannot receive Turkish enforcement because reciprocity is absent can still have legal relevance. Recognition may remain possible, and the underlying cause of action may have other consequences depending on applicable law.

Whether a fresh Turkish lawsuit can be filed must be analysed carefully; recognition, limitation and res judicata principles can affect that option.

The client should not assume that a failed tenfiz means the foreign litigation was legally meaningless.

Conclusion

Reciprocity under MÖHUK Article 54(a) can be established by treaty, foreign legislation or de facto judicial practice. The three bases are alternatives. The inquiry concerns enforcement of Turkish judgments in the foreign state, not general treatment of Turkish citizens. Because foreign law and practice can change, reciprocity should be verified with current official or authoritative material before filing. Recognition under Article 58 remains possible without reciprocity, which can provide a different route where compulsory execution is not required.
