Contract Disputes in Turkey: 12 Steps for Foreign Companies
Legal information notice
This publication provides general information on Turkish law as of its stated review date. It does not create an attorney–client relationship; documents, time limits, jurisdiction and current rules require a matter-specific assessment.
Contact usDirect answer: Contract disputes in Turkey should be managed by first identifying the exact parties, signed contract and later amendments; preserving delivery, performance, invoice, notice and payment evidence; classifying the breach and remedies; checking governing law, jurisdiction or arbitration; calculating principal, interest, penalties and provable loss; assessing mandatory commercial mediation; and coordinating interim protection, litigation, enforcement and settlement. A foreign company can usually begin this work remotely, but the correct Turkish route depends on the contract, relief sought, debtor, assets and current procedural rules.
This guide is for foreign suppliers, buyers, service providers, distributors, shareholders, investors and corporate creditors dealing with a Turkish counterparty or a contract connected with Turkey. It gives general legal information, not a prediction of outcome. Attorney Emirhan Keskin is registered with the Mersin Bar Association under registration number 5507. Initial document review and case planning can begin electronically.
Contract disputes in Turkey: first-screen table
| Question | Evidence to collect | Why it matters |
|---|---|---|
| Who is actually bound? | Signed contract, order, registry extract, guarantee, assignment and authority | Group companies, branches, directors and shareholders are not interchangeable |
| What was promised? | Specifications, scope, Incoterms, milestones, acceptance and change orders | The remedy depends on the precise obligation and agreed risk allocation |
| What is the breach? | Non-payment, delay, defect, refusal, confidentiality or exclusivity records | Termination, performance, price reduction and damages require different facts |
| Was notice valid? | Contractual notice clause, KEP, notary, courier and receipt data | A wrong address, sender or cure period can weaken a later remedy |
| Which law and forum apply? | Governing-law, court, arbitration and language clauses | Substantive law, procedure, service, evidence and enforcement may differ |
| Can a result be collected? | Debtor identity, asset, security, insolvency and competing-enforcement data | A legally strong claim can still have poor net recovery |
1. Identify the correct contract and parties
Start with the complete executed contract, not a sales presentation or unsigned template. Add every annex, specification, price schedule, order, confirmation, general term, addendum, side letter and later change. If several documents conflict, map their priority clause, signature dates and incorporation language.
Confirm the legal identity of each party. A Turkish subsidiary, parent, branch, shareholder, director, distributor and guarantor are separate unless a legal or contractual basis connects liability. Compare the name, trade-registry number, tax data, signature circular and contract signature. If a party merged, changed name, assigned the agreement or entered liquidation, document continuity.
2. Build a dated performance record
Prepare a chronology showing offer, acceptance, advance payment, manufacture, shipment, customs, delivery, inspection, acceptance, invoice, objection, cure request and termination. Attach the exact document proving each event. A short chronology helps reveal missing evidence and contradictory dates before a notice or claim is filed.
Actual conduct may matter where the parties departed from the written timetable or repeatedly accepted a different method. Preserve purchase orders, warehouse records, signed delivery notes, bills of lading, service reports, meeting minutes and payment references. Do not edit original electronic files; retain metadata and the system from which records were exported.
3. Classify the breach and the requested remedy
“Breach of contract” is not a single remedy. The problem may be non-payment, late performance, defective goods, incomplete service, refusal to accept delivery, unlawful termination, breach of exclusivity, misuse of confidential information or failure to meet a minimum-purchase commitment. State the obligation, due date, act or omission, and resulting loss separately.
The possible response may include performance, payment, repair or replacement, price reduction, suspension, termination, restitution, contractual penalty, damages, interest or a declaration. These remedies cannot simply be stacked. The contract, Turkish Code of Obligations, Turkish Commercial Code and any special statute determine compatibility, notice and election requirements.
4. Check notice, default and cure requirements
Read the notice clause before sending a demand. Verify the authorised sender, recipient, address, language, delivery method and when notice becomes effective. A general email to an operational employee may not satisfy a clause requiring notice to the registered office or a designated electronic address.
Default may occur automatically in some circumstances and require notice in others. A reasonable or contractually fixed cure period may be relevant before termination or substitute performance. Preserve proof of content as well as transmission: a courier receipt can prove that an envelope travelled, but not necessarily what the envelope contained.
For Turkish corporate counterparties, a notary notice or registered electronic mail system known as KEP may provide stronger evidence where appropriate. The correct form is transaction-specific. Sending an unnecessarily aggressive notice can trigger cross-default, suspension or termination provisions, so the requested remedy should be decided first.
5. Determine governing law
A written governing-law clause is the starting point, but it is not the end of the analysis. Turkey’s Law No. 5718 on Private International and Procedural Law contains conflict rules for contractual obligations. Party choice, the law most closely connected in the absence of an effective choice, overriding mandatory rules and public policy may all require review.
A clause selecting foreign substantive law does not automatically select a foreign court or foreign procedure. Nor does a Turkish court clause always make Turkish substantive law applicable. Separate the questions of governing law, forum, arbitration, evidence, limitation, interim measures and enforcement.
6. Determine court jurisdiction or arbitration
Examine every forum clause, including general terms incorporated by reference. A clause may choose Turkish courts, a foreign court, institutional arbitration or ad hoc arbitration. Its scope, exclusivity, written form, authority, arbitrability and relationship with later documents should be assessed before taking a procedural step.
If no effective clause exists, Turkish international and territorial jurisdiction can depend on the defendant, place of performance, branch, property, protective or exclusive rules and the relief sought. A filing made in the wrong forum can waste time and cost. A foreign judgment or foreign arbitral award also needs its own Turkish recognition or enforcement analysis.
For award-specific planning, see the foreign arbitral award enforcement in Turkey guide. For court judgments, use the foreign judgment recognition and enforcement guide.
7. Preserve commercial and electronic evidence
Commercial books, e-invoices, e-ledgers, bank records, email, KEP messages, enterprise-resource-planning data, delivery systems and messaging applications can be relevant. Evidential value depends on authenticity, completeness, lawful acquisition, the person who created the record and consistency with the rest of the file.
Keep native email files, headers, server export, access logs and unedited attachments. A screenshot can be a useful lead but may omit sender, recipient, time zone, thread, attachment or metadata. Establish a legal hold where staff turnover, automatic deletion or device replacement threatens evidence.
Do not access another person’s account or copy personal data without authority. Evidence collection must respect confidentiality, trade-secret and data-protection duties. Turkish counsel can help select preservation steps without creating a new compliance problem.
Evidence map for common contract claims
| Dispute | Core evidence | Frequent weakness |
|---|---|---|
| Unpaid goods or services | Contract, order, delivery/acceptance, invoice, ledger and demand | Invoice exists but delivery or correct debtor is not proved |
| Defective goods | Specifications, inspection, timely notice, samples, expert and loss records | Goods were altered or discarded before independent inspection |
| Delay | Agreed timetable, dependencies, extensions, notice and critical-path evidence | Claim ignores buyer-caused delay or accepted timetable changes |
| Wrongful termination | Termination clause, breach notices, cure, board authority and effective date | Notice invokes the wrong clause or omits required cure |
| Distribution dispute | Territory, exclusivity, targets, customer data, stock and termination record | Claim confuses company group conduct with the contracting party |
| Contractual penalty | Signed clause, triggering breach, reservation, performance and calculation | Penalty is claimed without analysing enforceability or double recovery |
8. Calculate principal, interest, penalty and damages
Prepare separate calculations for unpaid principal, contractual or statutory interest, currency, contractual penalty, direct loss, lost profit, cover purchase, storage, transport and mitigation expense. Identify the legal basis, period and supporting document for every line. Do not present gross turnover as lost profit without showing cost and causation.
Damages analysis usually requires breach, loss, causal connection and rules governing attribution or foreseeability under the applicable law. The injured party should take reasonable steps to limit avoidable loss and preserve evidence of those steps. Payments, returns, credits, insurance and tax treatment must be reflected to avoid double recovery.
A contractual penalty is not automatically payable exactly as invoiced in every case. The wording, trigger, commercial status of the parties, reservation of rights, partial performance, mandatory rules and relationship with damages require analysis. A foreign company should not assume that rules applied to a consumer or non-merchant operate identically between merchants.
9. Check limitation and contractual time bars
There is no safe universal online limitation period for every contract dispute in Turkey. The applicable law, contract type, remedy, due date, delivery, defect notice, agency, carriage, insurance, negotiable instrument and procedural history can change the period and starting point. Contractual notice or claim periods may operate separately.
Make a deadline table before settlement discussions. Include accrual, notice, acknowledgement, partial payment, mediation, enforcement, prior proceedings and cross-border service. Do not assume that a demand letter, negotiation or foreign filing suspends or interrupts a Turkish period without a legal basis.
10. Assess mandatory commercial mediation
Turkish law makes mediation a precondition to filing certain commercial actions, particularly covered monetary payment and compensation claims, and it expressly addresses certain actions connected with enforcement disputes. The scope has changed over time. The claim requested in the petition—not merely the heading “contract dispute”—must be classified under the current provisions.
Not every commercial disagreement is automatically subject to mandatory mediation. Arbitration, interim protection, non-monetary relief, special proceedings or a mixed set of claims may require a different analysis. Where mediation is a filing condition, the application, parties, claim description, final report and later petition should be consistent.
A foreign company can generally participate through a properly authorised lawyer, subject to the required authority and procedure. A settlement should state amount, currency, tax, payment date, security, default, release, confidentiality, costs and the treatment of pending litigation or enforcement. Its enforceability must be checked before signing.
11. Consider interim injunction or interim attachment
If delay risks making the right substantially more difficult to obtain or causing serious harm, an interim injunction may be considered under Turkish procedural law. For a monetary claim and a debtor-asset risk, interim attachment follows a different statutory framework. Neither measure is automatic; evidence, urgency, proportionality, jurisdiction, security and prompt execution matter.
Define the asset or conduct to be protected. A vague request to freeze everything can be disproportionate and ineffective. For monetary recovery, use the interim attachment in Turkey guide and begin a lawful asset investigation before assuming that litigation will produce payment.
12. Select litigation, enforcement or settlement
A liquid and sufficiently documented debt may support Turkish enforcement proceedings; a genuinely disputed breach, defect, set-off or damages claim may require litigation or arbitration. A contractual dispute can also involve both: an enforcement file, an objection, mandatory mediation and a court action may form one procedural chain.
Compare probable net recovery, not only the nominal claim. Consider court and enforcement fees, translation, service, expert examination, security, appeal, insolvency, competing creditors and management time. A staged strategy can preserve deadlines and evidence while leaving room for a secured settlement.
For invoice-led recovery, see unpaid invoice in Turkey and the broader debt collection in Turkey guide.
Termination, rescission and suspension
Do not use the words termination, rescission and cancellation as if they always have the same legal effect. Their consequences can differ for continuing and one-time contracts, completed performance, restitution, accrued payment, confidentiality, dispute-resolution clauses and claims that survive ending the relationship.
Before stopping performance, review reciprocal obligations, default, insecurity, force majeure, hardship, suspension and cure provisions. An unjustified suspension can become a breach itself. A termination notice should identify the contractual and legal basis, effective date, prior notice, cure history, reserved claims, return of property and transition duties.
Force majeure and hardship claims
A difficult or unprofitable contract is not automatically impossible. Analyse the defined event, foreseeability, control, prevention, notice, causal effect, mitigation and duration. The contract may provide extension, suspension, renegotiation or termination rather than damages. Government restrictions, transport disruption, exchange-rate movement and supply shortages require event-specific proof.
Hardship or adaptation claims are distinct from impossibility. The applicable law, risk allocation, currency clause, price-adjustment mechanism and actual economic impact must be documented. Continue to preserve rights while negotiations take place; informal renegotiation can otherwise create waiver or variation disputes.
Set-off, counterclaims and guarantees
Expect the Turkish counterparty to raise defective performance, delay, warranty cost, penalty, return, price reduction or set-off. Test each defence against timely notice, causation, supporting documents and the same governing-law analysis. A creditor should calculate the net position, not ignore a credible counterclaim.
Review bank guarantees, letters of credit, retention, pledge, suretyship, parent guarantees and title-retention terms separately. Their formal requirements, independence and demand conditions may differ from the main contract. Calling security without satisfying its wording can create urgent injunction and damages exposure.
Cross-border service, translation and company authority
Foreign documents may require apostille or legalisation, certified Turkish translation and current proof of corporate authority. The exact route depends on the issuing country, document and intended Turkish use. Names, registration numbers, signatory capacity and dates must match across the power of attorney and registry evidence.
International service can affect timetable and defence rights. A contract notice, procedural service and electronic communication are not interchangeable. Plan service early and preserve the recipient address and delivery proof relied upon.
Remote representation for foreign companies
The initial assessment can normally begin without travel. Send the signed contract, amendments, chronological summary, breach notices, invoices, delivery/acceptance record, payment history, forum clauses, counterparty registry details and known assets through a secure channel. Counsel can identify missing documents before originals are shipped.
For formal representation, a foreign company usually needs appropriate corporate authority and a power of attorney prepared for Turkish use. The signatory, corporate documents, certification, apostille/legalisation and translation route should be confirmed first. See the power of attorney from abroad guide.

Frequently asked questions
Can a foreign company sue a Turkish company in Turkey?
Potentially, yes. Jurisdiction, competent court, arbitration, governing law, mandatory mediation, security and service must be checked from the contract and current rules.
Does choosing Turkish law also choose Turkish courts?
No. A governing-law clause and a forum clause answer different questions. Each must be analysed separately.
Is mediation mandatory for every contract dispute?
No. Turkish law requires mediation before specified commercial actions, especially covered monetary claims and certain related actions. The actual relief and procedural route determine whether it applies.
Is an invoice enough to prove the claim?
Not always. Contract formation, correct debtor, delivery or service, acceptance, objections, credits and payment records should be assembled with the invoice.
Can the contract be terminated immediately?
That depends on the breach, contract, notice and cure requirements, urgency and applicable law. Wrongful termination can create a counterclaim.
Can assets be frozen before judgment?
A Turkish court may consider interim attachment or another measure where the specific legal and evidential conditions are met. Security and rapid execution can be required.
Can email and WhatsApp messages be evidence?
They may be relevant, but authenticity, completeness, lawful acquisition, participants, metadata and consistency matter. Preserve native data instead of relying only on screenshots.
Do company representatives need to travel to Turkey?
Usually the first review and many lawyer-led steps can be handled remotely. Attendance depends on the forum, evidence, hearing and authority requirements.
Can a foreign court judgment be executed directly?
Generally not without the required Turkish recognition or enforcement route. A foreign arbitral award follows a separate framework.
