Turkish Company Files a Lawsuit Despite an Arbitration Agreement: What Should the Foreign Party Do? – 2026 Updated Guide

What should a foreign party do when a Turkish company files a lawsuit despite an arbitration agreement? Learn about objections, deadlines, evidence, interim measures and legal remedies in Turkey.

A Turkish company may sometimes file a lawsuit in Turkey even though the parties have agreed to resolve their disputes through arbitration. When this happens, the foreign party should act quickly. The existence of an arbitration clause may provide a strong procedural defense, but the objection must usually be raised at the correct stage.

A foreign party should not ignore the lawsuit, assume that the Turkish court will automatically reject it or begin arguing the entire case without first protecting its arbitration rights. Failure to respond properly may create waiver, deadline and jurisdiction risks.

Can a Foreign Party Challenge a Turkish Lawsuit?

Yes. A foreign party may challenge Turkish court proceedings when the contract contains a valid arbitration agreement covering the dispute. The foreign party can request that the court decline to hear the case or dismiss the lawsuit on the appropriate procedural grounds.

The court may examine whether the arbitration clause exists, whether it is valid, whether the dispute falls within its scope and whether the foreign party objected in time. The court generally does not need to conduct a complete examination of the commercial merits before deciding this procedural issue.

The result depends on the wording of the contract, the parties’ conduct, the type of lawsuit, the arbitration seat and whether the subject matter is legally capable of arbitration.

What Is an Arbitration Agreement?

An arbitration agreement is a contractual commitment to submit a dispute to an arbitral tribunal rather than an ordinary national court. It may appear as a clause in the main contract or as a separate arbitration agreement signed by the parties.

A reliable arbitration clause should identify the parties, demonstrate a clear intention to arbitrate and describe the disputes covered by the agreement. It should also contain sufficient information concerning the arbitration institution or rules, seat, language and appointment of arbitrators.

An arbitration clause may remain effective even after the main contract is terminated, cancelled or alleged to be invalid. The arbitration agreement is often treated as legally separate from the other contractual provisions.

What Should the Foreign Party Do First?

The foreign party should immediately obtain and review the complete lawsuit file, service documents, contract, amendments and correspondence. The effective date of service is particularly important because procedural deadlines may begin from legally valid service rather than the date on which the company informally became aware of the case.

The foreign party should then prepare a procedural strategy focused on the arbitration agreement. A detailed merits defense, counterclaim or admission should not be filed before the arbitration objection has been properly preserved.

The appropriate response commonly includes:

1. Confirming how and when the lawsuit was served.
2. Reviewing the arbitration clause and all incorporated terms.
3. Determining whether the dispute falls within the clause.
4. Checking the arbitration seat, institution and applicable rules.
5. Raising the arbitration objection at the first appropriate opportunity.
6. Requesting the procedural result available under the applicable rules.
7. Considering whether arbitration should be commenced immediately.
8. Applying for urgent protection of assets or evidence if necessary.

The exact filing deadline depends on the type of proceeding and the legally effective service date. There is no safe reason to wait until the first hearing.

What If the Foreign Party Participates in the Merits?

Participation in the merits without raising the arbitration objection may create serious risks. For example, submitting extensive arguments about liability, payment, defective performance or damages may be interpreted as acceptance of the court proceedings in certain circumstances.

This does not mean that every procedural filing automatically waives arbitration. However, the foreign party should clearly state that it challenges the court proceedings because of the arbitration agreement and that any alternative merits arguments are made without waiving this objection.

A Turkish lawyer should carefully coordinate the procedural objection and any conditional defense. The wording of the first response can affect the foreign company’s ability to rely on arbitration later.

How Is the Scope of the Clause Determined?

Broad clauses covering disputes “arising out of or in connection with” the contract may include claims for payment, breach, termination, compensation, interpretation and related contractual obligations.

Narrow clauses may apply only to specific disputes, such as price, delivery or payment claims. A Turkish company may argue that its lawsuit is outside the arbitration clause, especially if the claim is based on tort, unfair competition, corporate liability or a separate guarantee.

The court may also consider whether the claim relates to multiple contracts. Purchase orders, guarantees, distribution agreements, financing documents and service contracts may contain different dispute resolution provisions.

A foreign parent company, subsidiary, director, bank, insurer or guarantor is not automatically bound by an arbitration agreement signed by another entity. Consent and the specific legal relationship between the parties must be examined separately.

Common Arguments Against the Arbitration Agreement

The foreign party may challenge the arbitration agreement where:

• The contract was never signed or accepted.
• The arbitration clause was not properly incorporated.
• The signatory lacked authority.
• The clause is unclear or contradictory.
• The dispute is outside the contractual scope.
• The clause applies to another agreement or transaction.
• Required negotiation or notice procedures were not completed.
• The arbitration agreement was validly terminated.
• The dispute is not capable of arbitration.
• The foreign party never consented to arbitration.
• The clause cannot bind a non-signatory party.

The strength of each argument depends on the contract, correspondence, company records and the parties’ conduct after signing. Digital acceptance, electronic signatures, online terms and email exchanges may also be important evidence in 2026 commercial disputes.

Which Disputes May Remain Before Turkish Courts?

Some disputes may be subject to mandatory court jurisdiction or public-order rules. Depending on the claim, difficulties may arise concerning certain real estate rights, insolvency, corporate status, employment protections, consumer rights, regulatory decisions and matters involving public authority.

A contractual claim may contain both arbitrable and non-arbitrable issues. The court may therefore examine whether the entire dispute can be referred to arbitration or whether certain parts must remain before a national court.

This analysis should be made claim by claim. The title of the lawsuit is not decisive; the legal substance and requested remedies are more important.

Can the Turkish Court Grant Interim Measures?

The existence of an arbitration agreement does not necessarily prevent a party from applying to a Turkish court for urgent interim protection. A foreign party may need court assistance to protect Turkish assets, bank accounts, documents, goods or digital evidence.

Possible applications may concern:

• Interim injunctions.
• Precautionary attachment.
• Preservation of evidence.
• Protection of company records.
• Measures concerning Turkish bank accounts.
• Preservation or inspection of goods.
• Assistance before the arbitral tribunal is constituted.

An application for interim protection does not automatically waive the right to arbitration, particularly where the application expressly reserves that right. The foreign party should avoid wording that suggests it has accepted the Turkish court’s authority to decide the merits.

What About Mandatory Mediation?

Certain commercial monetary disputes may be subject to a pre-litigation mediation requirement before a lawsuit can proceed. The existence of an arbitration clause may interact with this requirement, depending on the claim and the applicable procedural rules.

The foreign party should therefore examine whether the Turkish company completed the required preliminary steps, whether the lawsuit is procedurally admissible and whether the mediation process affected the arbitration agreement.

A mediation meeting should not automatically be treated as consent to Turkish court jurisdiction. Nevertheless, the foreign party should participate carefully and expressly preserve its arbitration position.

Service and Deadline Risks for Foreign Companies

A foreign company may be served through international service procedures, a Turkish branch, an authorized representative or another legally recognized method. Informal notice by email, messaging application or business correspondence may not always replace formal service.

The company should preserve the envelope, service certificate, electronic notification, court file information and all documents received. The date of effective service should be calculated carefully because an incorrect calculation may result in the loss of a procedural defense.

Where the company has no Turkish office, it may still need to appoint a Turkish lawyer under a valid power of attorney. Foreign corporate documents may require authentication, translation or other formal requirements before they can be used in Turkey.

What Evidence Should Be Preserved?

The foreign party should preserve the original agreement, arbitration clause, general terms, amendments, purchase orders, invoices, payment records and termination notices. Emails, electronic signatures, online platform records and cloud documents may help prove acceptance of the arbitration clause and the parties’ subsequent conduct.

Evidence showing that the Turkish company previously accepted arbitration can be particularly valuable. This may include arbitration notices, negotiation correspondence, draft procedural documents, references to an arbitration institution or earlier disputes handled under the same clause.

The foreign party should also preserve all documents relating to service of the Turkish lawsuit and avoid deleting or altering electronic records.

How Can Foreign Parties Prevent Similar Disputes in 2026?

International commercial contracts should clearly identify the arbitration institution, rules, seat, language, governing law and scope of disputes. They should also regulate emergency measures, electronic notices, remote hearings, consolidation, joinder and disputes involving affiliates or guarantors.

The contract should avoid contradictory provisions selecting both exclusive Turkish courts and mandatory arbitration unless the relationship between those provisions is clearly explained. Poorly drafted dispute resolution clauses can generate additional litigation before the merits are ever considered.
