Foreign Court Jurisdiction Clauses in Turkey: MÖHUK Article 47 and HMK Articles 17–18

1. MÖHUK Article 47 permits a foreign-court jurisdiction agreement within defined limits

International contracts often select a foreign court for disputes even though one party, performance, assets or evidence is located in Turkey. Turkish law deals directly with that situation in Article 47 of International Private and Procedural Law No. 5718.

Article 47(1) permits parties to agree that a dispute arising from an obligation relationship containing a foreign element will be heard by the court of a foreign state, provided Turkish territorial jurisdiction is not determined on an exclusive-jurisdiction basis. The agreement is valid if it can be proved by written evidence.

The provision is narrower than a general statement that “any foreign forum clause is enforceable.” The dispute must have a foreign element, must arise from an obligation relationship, must not fall within exclusive Turkish jurisdiction, and the jurisdiction agreement must satisfy the evidentiary requirement.

2. The dispute must carry a foreign element and arise from an obligation relationship

A foreign element can arise through party nationality or establishment, foreign place of performance, foreign transaction structure, overseas assets, foreign-law elements or other international connections. For a typical agreement between a Turkish company and a company established abroad, the international character is apparent.

Article 47 applies to disputes arising from obligation relationships. International sale, distribution, agency, service, licensing and financing contracts are common commercial examples. The provision should not be extended automatically to matters governed by exclusive jurisdiction or status rules outside the contractual-obligation framework.

Foreign investors should classify the dispute before relying on the clause. A contract may contain ordinary payment obligations together with real-estate rights, intellectual-property registration issues or corporate matters. A single forum clause does not necessarily displace all mandatory Turkish jurisdiction rules connected to those separate legal subjects.

The safest contract identifies the categories of dispute submitted to the chosen foreign court and coordinates the clause with any matters that must remain before Turkish authorities or courts.

3. A foreign-court clause cannot displace exclusive Turkish jurisdiction

Article 47 begins with a statutory limitation: the foreign-court agreement is available only where territorial jurisdiction is not determined on an exclusive basis. Where Turkish law gives a Turkish court exclusive jurisdiction, the parties cannot contract around that exclusivity by selecting a foreign state court.

This issue is especially important in disputes concerning rights in rem over Turkish immovable property, certain registry matters and other areas where Turkish procedural law assigns exclusive venue. An international contract connected with property in Turkey therefore needs separate review before a generic foreign-forum clause is copied into the document.

Exclusive jurisdiction should be distinguished from ordinary international jurisdiction. Article 40 of Law No. 5718 provides generally that Turkish courts’ international jurisdiction is determined by domestic territorial-jurisdiction rules. Article 47 allows party selection of a foreign court only within the non-exclusive part of that framework.

A foreign company should therefore ask two questions in order: would a Turkish court otherwise have international jurisdiction, and is that jurisdiction exclusive? Only then should the Article 47 foreign-court clause be evaluated.

4. Article 47 requires the agreement to be provable by written evidence

The foreign-court jurisdiction agreement is valid where it is proved by written evidence. In practice, the strongest proof is a signed written contract containing the court-selection clause itself.

Where contracts are concluded electronically or through a framework agreement plus purchase orders, the company should preserve the complete acceptance trail. The foreign forum clause should not appear only in a website term that cannot be shown to have been incorporated into the transaction.

Conflicting standard terms create particular risk. A supplier quotation may select German courts while the purchaser’s purchase order selects Istanbul courts. Before performance begins, the parties should execute a master clause that resolves the conflict rather than leaving forum selection to a later battle-of-forms dispute.

Amendments and renewals should preserve the clause deliberately. If the parties sign a replacement agreement without carrying forward the prior forum clause, the effect of the old clause on later transactions can become contested.

5. Article 47 changes when a Turkish court can proceed despite the foreign forum clause

The second sentence of Article 47(1) provides the operative consequence. The dispute can be heard before an otherwise competent Turkish court only where the chosen foreign court considers itself without jurisdiction or where no jurisdiction objection is raised in the Turkish court.

The clause therefore must be invoked procedurally. A defendant served with a Turkish lawsuit should not ignore the proceedings because a foreign-court clause exists. Turkish procedural deadlines for a jurisdiction objection must be respected.

Code of Civil Procedure Article 19 provides that where jurisdiction is not exclusive, an objection to territorial jurisdiction must be raised in the statement of defence. The defendant invoking lack of jurisdiction must identify the competent court in the manner required by the procedural rules. A late objection can result in the Turkish court continuing.

For cross-border contract management, the legal team should therefore flag forum clauses in the dispute-intake process. Service of a Turkish claim should immediately trigger review of the Article 47 clause and objection deadline.

6. Article 47(2) protects Turkish jurisdiction in employment, consumer and insurance disputes

Article 47(2) states that the jurisdiction of the courts identified in Articles 44, 45 and 46 cannot be eliminated by agreement of the parties. These provisions cover individual employment relationships, qualifying consumer contracts and insurance disputes.

Article 44 provides protective Turkish forums for employee claims. Article 45 contains consumer-jurisdiction rules, including the consumer’s residence or habitual residence in defined disputes. Article 46 governs insurance disputes and protects specified forums for the policyholder, insured and beneficiary.

A foreign business should therefore not treat a standard B2B forum clause as suitable for Turkish employment or consumer documentation. The weaker-party protective rules must be reviewed independently.

This distinction also matters for governing law. Law No. 5718 Articles 26 and 27 separately provide special conflict-of-laws protections for consumers and employees. Forum and governing-law clauses should be tested against both sets of protective rules.

7. Choosing Turkish courts is governed by HMK Articles 17 and 18

If parties wish to select one or more Turkish courts, Code of Civil Procedure No. 6100 Article 17 governs the domestic jurisdiction agreement. It states that merchants or public legal entities may designate one or more courts for a dispute that has arisen or may arise between them.

Unless the parties agree otherwise, an Article 17 clause is exclusive: the action may be brought only before the court or courts selected in the agreement. Parties who want the selected court to be additional rather than exclusive should say so expressly.

Article 18 then imposes validity conditions. A jurisdiction agreement cannot be made for matters over which the parties cannot freely dispose or for cases of exclusive jurisdiction. The agreement must be in writing, the legal relationship from which the dispute arises must be definite or determinable, and the authorised court or courts must be identified.

These requirements should be satisfied in the contract text itself. “Turkish courts are competent” is less precise than identifying the particular court location and legal relationship in the way Article 18 requires.

8. HMK Article 17 limits domestic jurisdiction agreements to merchants and public legal entities

Article 17 deliberately does not give every contracting person equal freedom to create a Turkish territorial-jurisdiction clause. The parties must be merchants or public legal entities within the statutory framework.

This restriction protects non-merchant parties from being forced by standard terms into a distant forum. A company should therefore verify the legal status of its Turkish counterparty rather than assuming every business customer is a merchant for Article 17 purposes.

Business-to-consumer terms require separate consumer-law and MÖHUK Article 45 analysis. Employment agreements likewise cannot rely on a commercial HMK Article 17 clause to strip the employee of protected forums.

In a contract between two companies operating commercially, Article 17 is commonly available, but Article 18’s writing, legal-relationship and court-identification requirements still need to be satisfied.

9. The chosen court and the underlying legal relationship must be identifiable

HMK Article 18 requires the legal relationship giving rise to the dispute to be certain or determinable. It also requires the court or courts selected by agreement to be shown. These rules prevent abstract advance jurisdiction arrangements with no defined relationship or forum.

A strong clause ties jurisdiction to the particular agreement and disputes arising from or relating to it. The selected forum should identify the location in a way that maps to the competent Turkish court system; subject-matter jurisdiction—commercial court, civil court or another competent court—continues to be determined by mandatory law.

A clause cannot manufacture subject-matter jurisdiction in a court that legally lacks it. Stating “Mersin Commercial Court” is useful where the dispute is a commercial case, but the law governing court competence still applies to the concrete claim.

If the parties select multiple Turkish courts, the clause should state whether the claimant can choose among them and whether statutory forums remain available. Otherwise, Article 17’s default exclusivity can create a result the parties did not intend.

10. Court selection does not select governing law

Forum and substantive law must be drafted separately. MÖHUK Article 24 governs the law applicable to contractual obligations; Article 47 governs a foreign-state court selection. Selecting English courts does not automatically select English substantive law, and choosing Turkish law does not automatically select Turkish courts.

The two clauses can point to different countries. That may be commercially rational, but it means the chosen court may need to apply foreign substantive law. Cost, expert evidence and translation should be considered before deliberately creating that split.

For the substantive-law analysis, see Governing Law in International Commercial Contracts: MÖHUK Article 24.

If the parties prefer arbitration instead of a state court, an arbitration clause should be drafted under the applicable arbitration law and convention framework rather than describing an arbitral institution as a “court.” Arbitration and state-court jurisdiction are legally different dispute-resolution mechanisms.

11. A foreign-court clause should be planned together with eventual enforcement in Turkey

If the selected foreign court issues a judgment and the successful party needs to seize assets in Turkey, recognition or enforcement under Law No. 5718 becomes the next stage. Article 50 provides that a final foreign civil judgment can be executed in Turkey only after an enforcement decision by the competent Turkish court.

Article 54 contains the core enforcement conditions: the required reciprocity basis, absence of a Turkish exclusive-jurisdiction conflict and—in the case of an exorbitant foreign jurisdiction with no real connection—an objection by the defendant, no manifest conflict with Turkish public policy, and proper notice/representation requirements.

Article 53 requires the authenticated judgment and proof of finality together with certified translations. A foreign company selecting an overseas court should therefore evaluate whether the resulting judgment can realistically be enforced where the counterparty’s assets are located.

A prestigious foreign forum can be commercially inefficient if enforcement in Turkey will be the inevitable second proceeding. The clause should be chosen based on dispute value, speed, interim-relief needs, evidence, language and asset location rather than corporate habit alone.

12. Draft the forum clause as part of the complete dispute-resolution architecture

A commercial forum clause should identify the disputes covered, the chosen court or courts, whether jurisdiction is exclusive, how governing law is selected, the language of notices and how contractual notices are served. Where the transaction includes guarantees, security documents or group-company undertakings, each related document should be checked for consistent forum provisions.

Foreign principals using Turkish agents or distributors should coordinate the forum clause with termination and statutory rights. See Commercial Agent Portfolio Compensation under TCC Article 122.

Foreign companies establishing a Turkish entity or branch should also separate corporate-jurisdiction issues from ordinary contract disputes. For branch establishment, see Foreign Company Branch in Turkey.

The final clause should be tested against three questions before signature: Is the selected forum legally available? Is it exclusive or non-exclusive as intended? Can the resulting judgment or award be enforced where the defendant’s assets are likely to be found?

Conclusion

MÖHUK Article 47 permits foreign-court jurisdiction clauses for foreign-element obligation disputes, but only outside exclusive Turkish jurisdiction and with written proof of the agreement. The protected Turkish forums for employment, consumer and insurance disputes cannot be contracted away under Article 47(2).

When parties instead select Turkish courts, HMK Articles 17–18 require an eligible merchant/public-entity relationship, written form, a defined or determinable underlying legal relationship and identification of the selected court or courts. The forum clause should always be coordinated with governing law and future enforcement rather than treated as isolated boilerplate.
