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.

Direct answer: To recover an unpaid invoice in Turkey, first identify the Turkish debtor precisely and prove the underlying supply, delivery or service—not only the invoice. Then review the contract, jurisdiction or arbitration clause, due date, currency, interest, limitation risk and debtor assets. Depending on the documents and likely defence, the route may involve a structured demand, Turkish enforcement proceedings, mandatory mediation before a commercial lawsuit, litigation or protective measures.

Unpaid invoice in Turkey debt recovery for foreign companies — A recovery strategy should connect the contract, performance evidence, debtor identity, due date and enforceable Turkish route.

This guide is for foreign suppliers, exporters, service providers, manufacturers, lenders and group companies owed money by a person or company connected with Türkiye. Attorney Emirhan Keskin is registered with the Mersin Bar Association under registration number 5507 and works from Mersin. An initial evidence and debtor review can begin electronically. Recovery, timing and asset availability cannot be guaranteed.

Unpaid invoice in Turkey: triage the claim first

Question	Evidence to inspect	Why it changes the route
Who exactly owes the money?	Contract, Turkish trade-registry name, MERSIS/tax number, address and signatory records	A brand, branch, director and company may be different legal actors
What was supplied?	Purchase order, contract, specification, delivery note, customs/transport record or service output	An invoice records a demand but may not by itself prove complete performance
When did payment become due?	Payment clause, invoice, acceptance milestone, reminder and account statement	Default, interest, limitation and enforcement timing depend on the due-date analysis
What does the debtor dispute?	Emails, defect notice, return, set-off, credit note, complaint and settlement correspondence	A documented merits dispute may favour a different strategy from an uncontested debt
Which forum applies?	Jurisdiction, arbitration, governing-law and service clauses	A Turkish enforcement office, Turkish court or arbitral tribunal may not have interchangeable authority
Are assets at risk?	Verified registries, known receivables, property, vehicles, bank relationships and disposal evidence	Protective relief requires legal grounds and evidence; suspicion alone is not enough

1. Identify the Turkish debtor correctly

Do not start proceedings against a trade name copied from an email signature. Obtain the exact registered name, legal type, registration or MERSIS number, tax information and registered address. Check whether the contracting party is a Turkish company, branch, sole trader, individual guarantor, distributor or another group entity.

A director or shareholder is not automatically personally liable for every company invoice. A guarantee, negotiable instrument, tort, unlawful distribution, capital or management issue may create a separate analysis, but liability should not be alleged without the document and statutory basis. Name changes, mergers, liquidation and deregistration also affect service and recovery planning.

2. Build evidence beyond the invoice

The strongest file shows offer, acceptance, performance, delivery or benefit, due date and non-payment as one chain. Gather the signed contract or accepted terms, purchase order, order confirmation, invoice, delivery note, bill of lading, customs record, warehouse receipt, installation record, service report, timesheet, acceptance email and bank statement.

If the contract was concluded by email or platform, preserve complete messages with dates, senders, attachments and headers where useful. Export records from the system in a form that can later be explained. A cropped screenshot may hide context and authenticity. Keep the original electronic files and document how they were obtained.

Is an invoice alone enough?

Not necessarily. The evidential weight of an invoice depends on the parties’ commercial relationship, accounting and trade records, delivery/performance evidence, objections and applicable commercial rules. An invoice created unilaterally does not automatically prove that the recipient ordered and received everything stated.

Conversely, the absence of a wet-ink contract does not always mean there is no claim. Purchase orders, repeated course of dealing, electronic communications, transport records, partial payment, account confirmations and the debtor’s admissions can be important. The complete evidence should be assessed before choosing an enforcement or lawsuit strategy.

3. Review jurisdiction, arbitration and governing law

A clause selecting foreign law does not automatically mean that no Turkish procedure is available, and a Turkish debtor does not automatically make every Turkish court competent. Review the jurisdiction clause, arbitration agreement, place of performance, defendant address, transaction type and mandatory rules together.

If an arbitral tribunal or foreign court has already issued a decision, the next issue may be recognition and enforcement rather than a new invoice lawsuit. See the foreign judgment and arbitral award enforcement guide. Starting the wrong merits proceeding can waste time and create jurisdiction costs.

4. Calculate principal, currency and interest

Prepare a transparent ledger separating invoice principal, credit notes, returns, partial payments, contractual interest, default interest, taxes and costs. Identify the contractual currency and the date/payment mechanism claimed for conversion. Do not combine several invoices into one unexplained balance.

Interest depends on the contract, transaction, parties, default and applicable law. Rates and statutory references can change; the relevant period must be calculated rather than inserting today’s rate across the entire claim. The Central Bank’s official rediscount and advance-rate page is one current official reference, but it does not determine every claim automatically.

5. Send a useful demand, not an empty threat

A pre-action demand should identify the parties, contract, invoices, performance, due dates, payments credited, precise outstanding amount, payment channel and a realistic response date. Attach or identify the core evidence. Address known objections instead of pretending they do not exist. Where non-payment is part of a wider breach, defect, termination or damages dispute, follow the contract disputes in Turkey framework before selecting enforcement or litigation.

The method of service and wording may affect proof, default, costs, settlement and later arguments. A message saying “pay immediately or we will seize everything” is neither a legal strategy nor a guarantee of action. Preserve delivery and response records and do not make misleading claims about court orders or asset freezes.

6. Turkish enforcement proceedings

For eligible monetary claims, a creditor may consider Turkish enforcement proceedings without first holding a judgment. The enforcement office issues the relevant payment order through the statutory process. The debtor may pay, remain inactive or object. The type of instrument, claim and objection determines the next route.

An objection can stop or reshape an ordinary enforcement path, requiring the creditor to evaluate removal or annulment of the objection, evidence, deadlines and court/tribunal jurisdiction. A proceeding should not be filed merely to pressure a debtor where the creditor cannot document the debt or jurisdiction. Official enforcement-office structures can be checked through the Ministry of Justice Enforcement Affairs Department.

7. Mandatory mediation and commercial litigation

Many Turkish commercial lawsuits concerning the payment of money require completion of pre-action mediation as a condition of bringing the lawsuit. The official Mediation Department FAQ explains the statutory categories and subsequent amendments, including specified commercial payment, compensation and enforcement-related actions. The claim and requested remedy must be classified under the current text.

Mediation is not the same as informal debt collection and does not guarantee settlement. A foreign company should authorise the correct participant, prepare its evidence and define settlement limits, currency, instalments, security, releases, costs, default consequences and enforceability before the meeting. If no settlement is reached, preserve the final record required for the next proceeding.

8. Interim attachment and protective measures

Where there is a concrete risk to recovery, interim attachment or another protective measure may be considered under its statutory conditions. The creditor generally needs to show the nature and maturity of the claim or the relevant special ground, provide evidence and address security. A court decides; the filing itself does not freeze assets. The interim attachment in Turkey guide explains the current conditions, security and ten-day enforcement deadline.

Asset concerns should be documented with lawful and current evidence. A debtor’s refusal to answer an email does not alone prove fraudulent disposal. Protective measures also have follow-up and service requirements, so the merits route and enforcement plan must be prepared at the same time.

Enforcement, lawsuit or negotiation?

Route	May fit when	Main risk to assess
Structured demand/negotiation	Identity and evidence are clear; debtor is contactable; commercial resolution remains realistic	Delay, limitation, asset movement or admissions drafted poorly
Ordinary enforcement proceeding	Eligible monetary claim and Turkish enforcement jurisdiction can be supported	Debtor objection, service, subsequent action and cost exposure
Commercial mediation then lawsuit	Merits, damages, objection or declaratory issues require judicial determination	Mandatory precondition, court jurisdiction, evidence and duration
Arbitration	Valid arbitration agreement covers the dispute	Scope, tribunal jurisdiction, cost, interim relief and award enforcement
Recognition/enforcement	An eligible foreign judgment or award already exists	Finality, service, public policy, treaty/statutory conditions and Turkish execution
Protective measure	Statutory grounds and evidence show a real recovery risk	Security, court discretion, wrongful-measure exposure and mandatory follow-up

Asset investigation without unlawful shortcuts

Begin with lawful public and client-held information: registered company records, addresses, known contracts, payment accounts, vehicles or property previously disclosed, and prior enforcement data accessible through authorised channels. Court and enforcement tools may provide further information only within an established legal process and applicable access rules. The asset investigation in Turkey guide provides a source, access, ownership, priority and net-value framework.

Do not buy leaked banking, population or telecommunications data. An online claim that a company owns an asset may be outdated or concern another entity. Asset ownership, liens, priority, value and saleability are separate questions. A successful judgment against an insolvent shell may not produce payment.

Foreign documents, translations and service

Foreign corporate and public documents may require certification, apostille or legalisation and sworn Turkish translation. A commercial contract or invoice is not automatically apostilled merely because it originated abroad; authentication requirements depend on the document and how it will be used. Confirm the required form before incurring translation costs.

Service on a Turkish debtor and service abroad follow formal rules. Contractual notice, notarial notice, mediation invitation, enforcement payment order and court service are not interchangeable. Preserve the registered address and any proof that the debtor used a different operational address.

Remote representation from outside Türkiye

A foreign creditor can usually begin the review without travelling. Send legible electronic copies, a ledger and chronology. If formal representation is accepted, the required authority can be prepared for the specific enforcement, mediation, litigation, settlement and collection tasks. Corporate signatory documents must also prove who can grant authority for the foreign company.

Use the power of attorney for Turkey from abroad guide before signing. A consular route available to a private individual should not automatically be assumed for a foreign legal entity.

An 8-step recovery workflow

Verify the debtor: exact registered identity, address, status and responsible contracting entity.
Build the evidence chain: agreement, order, performance, delivery, acceptance, invoice, due date and non-payment.
Map the dispute: defects, set-off, returns, credits, guarantees, arbitration and governing-law objections.
Calculate the claim: invoice-by-invoice principal, payments, currency and legally supportable interest.
Assess urgency: limitation, service, asset risk, insolvency indicators and protective-measure evidence.
Select the route: demand, enforcement, mediation/litigation, arbitration or judgment enforcement.
Prepare authority: transaction-specific power of attorney and foreign corporate documents.
Track recovery: service, objections, deadlines, settlement security, asset execution and net remittance.

Frequently asked questions

Can I recover an unpaid invoice in Turkey without travelling?

Usually the initial review and many formal steps can be handled remotely under suitable authority. Personal attendance depends on the dispute, evidence and directions of the mediator, tribunal, court or authority.

Is the invoice alone sufficient?

Not automatically. The underlying order, performance, delivery, acceptance, due date and any objection should be proved as a coherent file.

Can enforcement start without a court judgment?

For eligible monetary claims, Turkish ordinary enforcement may be considered without a prior judgment. A debtor objection and the nature of the documents can require a subsequent court route.

Must we mediate before suing?

Many commercial lawsuits concerning payment of money are subject to mandatory pre-action mediation. The claim, remedy and current statutory exceptions must be checked.

Can the debtor’s assets be frozen immediately?

Not merely because an invoice is unpaid. Interim attachment or another measure requires statutory grounds, evidence and a court decision; security and follow-up obligations may apply.

Can a director be pursued personally?

Not simply because the company did not pay. A guarantee or a separate statutory or wrongful-act basis must be established.

Which currency and interest can be claimed?

That depends on the contract, transaction, default, applicable law and requested remedy. Prepare a transparent period-by-period calculation.

How long will recovery take?

No fixed period can be promised. Service, objection, mediation, evidence, court workload, appeals and asset availability all affect timing.

Can I send documents electronically?

Yes for the first assessment. Formal proceedings may later require certified corporate records, originals or accepted Turkish translations.
