Filing a commercial lawsuit in Turkey is a structured legal process that requires careful preparation, procedural compliance, and strategic planning. For foreign investors and companies, understanding this process is essential to protect legal rights and enforce commercial claims effectively.
In Turkey, commercial disputes are handled under Commercial Law, the Turkish Commercial Code, and procedural legislation. Foreign parties have equal standing before Turkish courts, but they must comply with procedural rules and documentation requirements. In 2026, digitalization of court systems and mandatory mediation processes have made litigation more efficient, yet still complex for those unfamiliar with the system.
This guide explains step by step how to file a commercial lawsuit in Turkey.
Step 1: Identify the Nature of the Dispute
Before filing a lawsuit, it is essential to determine whether the dispute qualifies as a commercial matter.
Commercial disputes typically include:
- Contract breaches
- Debt collection
- Corporate disputes
- Shareholder conflicts
Correct classification ensures that the case is filed before the appropriate court.
Step 2: Mandatory Mediation Process
In Turkey, mediation is often a mandatory step before filing a commercial lawsuit.
The parties must apply to a mediator and attempt to resolve the dispute amicably.
If mediation fails, a final report is issued, allowing the claimant to proceed to court.
Failure to complete this step may result in rejection of the lawsuit.
Step 3: Determine the Competent Court
Commercial lawsuits must be filed before the competent Commercial Court.
Jurisdiction depends on factors such as:
- Location of the defendant
- Place of contract performance
- Contractual jurisdiction clauses
Choosing the correct court is critical to avoid delays.
Step 4: Prepare the Statement of Claim
The statement of claim is the most important document in the litigation process.
It must include:
- Identification of the parties
- Description of the dispute
- Legal arguments
- Claims and requests
- Supporting evidence
The document must be clear, detailed, and legally structured.
Step 5: Collect and Submit Evidence
Evidence is essential for proving the claim.
Common types of evidence include:
- Contracts
- Invoices
- Correspondence
- Financial records
All evidence must be submitted to the court in accordance with procedural rules.
Strong evidence significantly increases the chances of success.
Step 6: Filing the Lawsuit
Once all documents are prepared, the lawsuit is filed with the court.
This involves:
- Submitting the statement of claim
- Paying court fees
- Registering the case
After filing, the court assigns a case number and begins proceedings.
Step 7: Court Proceedings
The litigation process includes several stages.
These typically involve:
- Exchange of written submissions
- Evidence examination
- Court hearings
Both parties present their arguments and evidence during this process.
The court evaluates the case and issues a decision.
Step 8: Requesting Interim Measures
During litigation, the claimant may request interim measures to protect rights.
These may include:
- Freezing assets
- Seizing property
- Preventing certain actions
Interim measures are particularly important in high-risk cases.
Step 9: Court Decision and Judgment
After evaluating the case, the court issues a judgment.
The decision may:
- Accept or reject the claim
- Award compensation
- Order performance of obligations
The judgment is binding unless appealed.
Step 10: Appeal Process
Parties have the right to appeal the court’s decision.
The appeal process allows higher courts to review the case.
This stage ensures legal accuracy and consistency.
Step 11: Enforcement of the Judgment
Once the decision becomes final, it must be enforced.
Enforcement is carried out through execution proceedings.
This may involve:
- Seizure of assets
- Collection of debts
- Enforcement of obligations
Effective enforcement is crucial for achieving results.
