Learn when commercial mediation is mandatory before filing a lawsuit in Turkey, how to apply, applicable deadlines, costs, settlement enforcement, exceptions, and risks for foreign companies under the 2026 rules.

Commercial mediation has become a central part of dispute resolution in Turkey. Before filing certain commercial lawsuits, the claimant must first apply to a mediation bureau and complete the mandatory mediation process. Failure to satisfy this procedural requirement may result in the lawsuit being dismissed without the court examining the merits.

This requirement is particularly important for foreign companies, international investors, shareholders, suppliers, distributors, contractors, financial institutions, and businesses seeking to recover commercial debts in Turkey. A foreign claimant may have a strong contractual case but still suffer delay or dismissal by starting litigation without first completing the required mediation stage.

The principal rules are contained in the Turkish Commercial Code No. 6102, particularly Article 5/A, and the Law on Mediation in Civil Disputes No. 6325. The mediation legislation applies to eligible private-law disputes, including disputes containing a foreign element, provided that the parties may freely dispose of the subject matter.

This 2026 guide explains when commercial mediation is mandatory, how the procedure works, which claims are covered, and what foreign businesses should do before commencing proceedings in Turkey.

What Is Mandatory Commercial Mediation?

Mandatory commercial mediation is a procedural step that must be completed before certain commercial claims can be filed before a Turkish court.

The requirement does not mean that the parties must settle. It means that the claimant must properly apply for mediation, participate in the statutory process, and obtain a final mediation record before commencing the lawsuit.

The mediator does not act as a judge and cannot impose a decision. The mediator facilitates negotiations, identifies the disputed issues, and assists the parties in exploring a voluntary settlement.

If no settlement is reached, the claimant may proceed with litigation after the mediation process has formally ended.

Which Commercial Claims Require Mediation Before Litigation?

Under Article 5/A of the Turkish Commercial Code, mandatory mediation generally applies to qualifying commercial disputes involving claims for:

• Payment of money
• Compensation
• Cancellation of an objection in enforcement proceedings
• Negative declaratory relief concerning an alleged debt
• Recovery of money paid without legal obligation

The decisive issue is not merely whether the parties are companies. The court examines whether the dispute qualifies as a commercial dispute and whether the specific form of relief falls within the statutory scope.

Typical claims subject to mandatory commercial mediation may include:

• Unpaid invoice claims
• Purchase price disputes
• Compensation for breach of a commercial contract
• Distribution and dealership disputes
• Commercial lease payment claims
• Construction and supply contract receivables
• Agency commission claims
• Freight and logistics receivables
• Insurance compensation disputes of a commercial nature
• Banking and finance receivables
• Share purchase agreement payment disputes
• Post-closing monetary claims
• Commercial loan repayment disputes
• Claims arising from defective goods or services
• Cancellation-of-objection actions following debt enforcement
• Negative declaratory actions concerning disputed commercial debts
• Restitution actions seeking repayment of amounts collected through enforcement

The legal characterization of the claim should be completed before filing the mediation application. An incomplete or incorrectly defined application may create disputes about whether the later lawsuit concerns the same subject matter.

Does Every Commercial Dispute Require Mandatory Mediation?

No. Not every dispute involving a company automatically falls within mandatory mediation.

The requirement depends on the nature of the dispute and the relief requested. Some corporate disputes may involve declaratory, constitutive, or status-related remedies rather than payment or compensation.

Examples requiring separate legal assessment include:

• Annulment of general assembly resolutions
• Invalidity of board resolutions
• Removal of directors
• Corporate books and information requests
• Determination of share ownership
• Registration and cancellation requests
• Certain dissolution proceedings
• Challenges relating to capital increases
• Requests primarily concerning corporate status
• Non-monetary intellectual property claims
• Urgent interim relief applications

A claim may contain both monetary and non-monetary elements. In such cases, each request must be analyzed separately to determine whether mediation is a precondition for all or part of the lawsuit.

Commercial Mediation and Shareholder Disputes

Shareholder disputes frequently combine contractual, corporate, and financial claims.

Mandatory mediation may apply where a shareholder seeks:

• Payment under a share purchase agreement
• Compensation for breach of a shareholders’ agreement
• Collection of a shareholder loan
• Recovery of an unpaid purchase price
• Damages arising from misrepresentation
• Compensation for breach of warranties
• Payment under put-option or call-option arrangements
• Financial relief following breach of an exit agreement

By contrast, a lawsuit seeking annulment of a general assembly resolution or determination of a corporate status issue may require a different procedural analysis.

Foreign shareholders should therefore avoid assuming that the entire dispute is either subject to mediation or exempt from it. The specific causes of action and requested remedies should be separated before proceedings begin.

How Is a Mandatory Mediation Application Filed?

The application is generally submitted to the competent mediation bureau associated with the courthouse determined under the statutory territorial rules.

Where no mediation bureau exists, the designated court registry performs the relevant administrative function.

The application should identify:

• The claimant
• The opposing party
• Available contact information
• The commercial relationship
• The disputed contract or transaction
• The type of claim
• The amount claimed, where known
• The principal allegations
• Any related enforcement proceedings

A vague application may create difficulties later. The scope stated in the application should correspond to the claims intended to be pursued in court.

Foreign companies should also ensure that corporate names, registered addresses, trade registry details, tax information, and representative authority are accurately stated.

How Is the Mediator Appointed?

In mandatory mediation, the mediator is generally appointed through the official system unless the parties jointly agree on a registered mediator.

The mediator must be registered in the official mediation register. The mediator then contacts the parties, arranges the first meeting, explains the process, and manages the negotiations impartially.

The mediator does not represent either party and does not provide independent legal advice to one side.

For this reason, each party may participate with its own lawyer. In complex commercial disputes, legal representation is particularly important because proposed settlement terms may affect taxation, guarantees, enforcement rights, corporate approvals, confidentiality, and future liability.

How Long Does Commercial Mediation Take?

For disputes subject to mandatory commercial mediation, the mediator is generally expected to complete the process within six weeks from appointment. This period may be extended by up to two additional weeks where necessary. The Ministry of Justice has also referred to the commercial mediation timetable as a six-week period with a possible two-week extension.

The process may end earlier where:

• The parties reach an agreement
• One party refuses to participate
• The parties cannot be contacted
• The mediator determines that settlement is impossible
• The dispute is not suitable for mediation
• The statutory period expires

Although the formal process is relatively short, preparation should begin immediately. Commercial cases often require examination of contracts, account statements, invoices, correspondence, expert calculations, and corporate records before meaningful negotiations can occur.

What Happens to Limitation and Forfeiture Periods?

A properly initiated mandatory mediation process affects the running of relevant procedural time periods under the applicable legislation.

Nevertheless, foreign claimants should not wait until the last day of a limitation or forfeiture period. Errors concerning the competent bureau, identity of the respondent, scope of the application, or date of commencement can create serious risks.

Where a claim is approaching a deadline, the application should be prepared and filed without delay.

Must the Parties Attend the Mediation Meeting?

The parties may attend personally or through duly authorized representatives, subject to the applicable representation rules.

Companies generally participate through authorized corporate representatives and may also be represented by lawyers. A foreign company should verify whether the person attending has sufficient authority to negotiate and sign a binding settlement.

Participation should not be treated as a formality. Failure to attend the first meeting without a valid excuse may have adverse consequences regarding litigation costs, depending on the applicable rules and the court’s assessment.

The participating representative should understand:

• The facts of the dispute
• The company’s settlement position
• The minimum acceptable outcome
• The available evidence
• Applicable payment limits
• Required corporate approvals
• Tax and accounting implications

Can a Foreign Company Participate Remotely?

International parties may often participate through available communication methods where the mediator and procedural conditions permit.

Remote participation may be especially useful where:

• The company’s directors are abroad
• The dispute involves multiple jurisdictions
• Travel would be disproportionate
• The negotiations require foreign counsel or interpreters
• The parties operate in different time zones

The parties should agree in advance on identity verification, representation documents, confidentiality, interpretation, and signature arrangements.

Is an Interpreter Allowed?

Yes. Where a foreign party or representative does not speak Turkish sufficiently, interpretation may be required to ensure informed participation.

The parties should determine:

• Who will select the interpreter
• Who will bear the cost
• Whether confidentiality obligations will be signed
• Whether the settlement will be bilingual
• Which language will prevail in case of inconsistency

A poorly translated settlement agreement may generate a new dispute instead of resolving the existing one.

Is Mediation Confidential?

Confidentiality is one of the principal advantages of mediation.

Statements, settlement offers, admissions, and documents produced specifically for the mediation process are generally protected under the mediation framework. The parties, mediator, lawyers, interpreters, and other participants must observe the applicable confidentiality obligations.

However, pre-existing evidence does not automatically become unusable merely because it was also presented during mediation. Parties should distinguish between independent commercial evidence and confidential settlement communications.

This distinction is particularly important in international disputes involving parallel litigation, arbitration, internal investigations, or regulatory proceedings.

What Happens If the Parties Reach an Agreement?

If the parties settle, the terms are recorded in a written mediation agreement.

A carefully drafted commercial settlement may include:

• Principal payment amount
• Interest
• Payment dates
• Currency
• Exchange-rate mechanism
• Default consequences
• Security or guarantees
• Release of claims
• Withdrawal of enforcement proceedings
• Allocation of costs
• Tax responsibility
• Confidentiality
• Non-disparagement
• Return of documents or property
• Termination of contracts
• Governing law
• Dispute resolution for future breaches

The settlement should clearly state whether it resolves the entire commercial relationship or only specific claims.

Ambiguous releases should be avoided. A broad release may unintentionally extinguish unknown or unrelated claims, while a narrow release may leave significant disputes unresolved.

Is a Mediation Settlement Enforceable?

A mediation settlement may acquire enforceability under the conditions set out in Turkish mediation law.

Depending on how the agreement was concluded and signed, an enforceability annotation may be required. Certain agreements signed by the parties, their lawyers, and the mediator may enjoy stronger direct enforceability under the statutory framework.

Because enforcement requirements may depend on the document’s form, parties should structure the settlement correctly at the time of signature rather than attempting to repair it after a breach.

What Happens If No Settlement Is Reached?

If the parties do not settle, the mediator issues a final record confirming the outcome.

The claimant may then file the lawsuit and must comply with the procedural requirement concerning submission of the final mediation record or related information.

The final record should accurately identify:

• The parties
• The dispute
• The application date
• Meeting details
• The result
• The completion date

The lawsuit should remain consistent with the dispute submitted to mediation. A substantial mismatch may lead to objections regarding fulfillment of the mandatory precondition.

What Happens If a Lawsuit Is Filed Without Mediation?

Where mandatory mediation applies and the claimant files a lawsuit without completing the process, the court may dismiss the case on procedural grounds without examining whether the claimant is substantively right.

This creates serious consequences:

• Loss of time
• Additional legal expenses
• Possible limitation-period risks
• Procedural cost exposure
• Delayed debt recovery
• Weakened negotiation position
• Enforcement complications

A claimant should therefore conduct a mandatory-mediation analysis before submitting any commercial statement of claim.

Is Mandatory Mediation Required Before Debt Enforcement?

Mandatory mediation generally concerns filing specified lawsuits rather than merely commencing ordinary debt enforcement proceedings.

However, when the debtor objects to enforcement and the creditor later files an action for cancellation of the objection, mandatory commercial mediation may apply before that lawsuit is filed.

Similarly, mediation may be required before certain negative declaratory or restitution actions connected with enforcement proceedings.

The timing and sequence of enforcement, mediation, and litigation should therefore be planned together.

Can Interim Measures Be Requested Before Mediation Ends?

Urgent protection may still be necessary while the mediation process is pending.

Depending on the dispute, a party may consider seeking:

• Interim attachment
• Preliminary injunction
• Preservation of evidence
• Protection of commercial books
• Prevention of asset transfers
• Protection against dissipation of property

Mandatory mediation should not be misunderstood as a requirement to remain passive while assets disappear or evidence is destroyed. The availability and conditions of interim protection must be assessed separately.

Does Mandatory Mediation Apply When There Is an Arbitration Clause?

An arbitration clause may remove the dispute from the ordinary court litigation route, but the effect of mandatory mediation must be assessed according to the wording of the clause, the nature of the claim, and the selected arbitral framework.

Parties should review whether the contract establishes:

• Direct arbitration
• Negotiation followed by arbitration
• Mediation followed by arbitration
• A multi-tier dispute resolution procedure
• Mandatory notice periods
• Institutional pre-arbitration requirements

Failure to comply with a contractual escalation clause may create jurisdictional or admissibility disputes in arbitration.

Commercial Mediation in Cross-Border Disputes

Turkish mediation law expressly covers eligible private-law disputes containing a foreign element.

Cross-border mediation may involve additional issues such as:

• Foreign governing law
• International arbitration clauses
• Parallel foreign litigation
• Overseas assets
• Foreign currency payments
• Sanctions compliance
• International tax consequences
• Corporate authorization requirements
• Translation and legalization
• Enforcement outside Turkey

A settlement intended to operate in more than one country should be reviewed from the perspective of every relevant jurisdiction.

The Singapore Convention and International Settlements

International commercial settlements resulting from mediation may also require consideration of the United Nations Convention on International Settlement Agreements Resulting from Mediation, commonly known as the Singapore Convention.

Turkish legislation has introduced measures aimed at aligning domestic mediation practice with the Convention framework.

Whether a particular settlement qualifies for cross-border enforcement depends on the Convention’s scope, applicable reservations, procedural requirements, and the states in which enforcement is sought.

Who Pays the Mediation Costs?

Costs depend on whether the mediation is mandatory or voluntary, whether the parties settle, the duration of the meetings, the value of the dispute, and the applicable tariff.

The 2026 Minimum Mediation Fee Tariff was published in the Official Gazette dated December 26, 2025, No. 33119. It distinguishes between disputes involving monetary claims and disputes that cannot be valued in money.

In mandatory mediation files ending without settlement, statutory payment rules may apply. Where settlement is reached, the mediator’s fee and its allocation should be expressly addressed in the agreement.

The parties may also incur costs for:

• Lawyers
• Interpreters
• Financial advisers
• Valuation experts
• Travel
• Translation
• Corporate documentation
• Tax advice

The 2026 Position for Businesses in Turkey

As of 2026, businesses should treat mandatory mediation as a substantive stage of dispute management rather than a box-checking exercise.

The legal framework remains based principally on:

• Turkish Commercial Code Article 5/A
• Law on Mediation in Civil Disputes No. 6325
• Relevant procedural legislation
• Current Ministry of Justice practices
• The 2026 Minimum Mediation Fee Tariff

The 2026 tariff was officially published before the beginning of the year and governs applicable minimum fee calculations for mediation services during 2026.

Companies should confirm the legislation and tariff in force on the actual application date because procedural rules, monetary thresholds, official practices, and fee schedules may change.

Common Mistakes Made by Foreign Companies

Foreign businesses commonly make the following errors:

• Filing a lawsuit before completing mandatory mediation
• Naming the wrong Turkish legal entity
• Using an outdated company address
• Defining the dispute too narrowly
• Omitting related monetary claims
• Sending a representative without settlement authority
• Failing to prepare a Turkish power of attorney
• Ignoring limitation periods
• Signing a settlement without tax review
• Using unclear foreign-currency clauses
• Failing to regulate default consequences
• Assuming that mediation correspondence can be freely used in court
• Overlooking parallel arbitration or foreign proceedings
• Signing a release broader than intended

These mistakes can be avoided through early legal preparation.

How to Prepare for Commercial Mediation

A business should prepare a structured case file containing:

• Executed contracts and amendments
• Invoices
• Delivery records
• Account statements
• Payment evidence
• Notices of default
• Emails and commercial correspondence
• Expert reports
• Corporate resolutions
• Powers of attorney
• Settlement authority documents
• Enforcement records
• Interest calculations
• A realistic litigation-risk analysis

The company should also calculate the commercial value of settlement by considering litigation duration, recoverability, enforcement costs, currency exposure, reputational impact, and the importance of preserving the business relationship.

Why Legal Representation Matters

A mediator manages the negotiation process but does not protect one party’s individual legal interests.

A commercial lawyer can:

• Determine whether mediation is mandatory
• Select the correct claims and respondents
• Protect limitation periods
• Prepare the application
• Assess evidence
• Calculate principal and interest
• Negotiate settlement terms
• Draft enforceable agreements
• Coordinate cross-border issues
• Prepare the lawsuit if settlement fails

For foreign companies, legal representation also helps manage translation, representation authority, corporate approvals, and communication with Turkish institutions.
