Turkish Exporter Is Not Paid by an Overseas Buyer: CISG and Debt Recovery Options (2026 Updated Guide)

An overseas buyer fails to pay a Turkish exporter. Learn how the CISG, contract terms, payment evidence, interest, termination, arbitration and international debt recovery may affect the exporter’s legal options.

A Turkish exporter that delivers goods to an overseas buyer but does not receive payment can face a difficult cross-border recovery problem. The buyer may dispute product quality, claim late delivery, request an unjustified discount, refuse to honor an invoice or simply stop communicating after receiving the goods. In international sales, the exporter should not treat the dispute as an ordinary unpaid invoice. The governing law, United Nations Convention on Contracts for the International Sale of Goods (CISG) where applicable, jurisdiction or arbitration clause, delivery terms, documentary evidence, buyer’s assets and enforcement possibilities should be examined together. The strongest strategy is usually to secure the evidence immediately, determine the legal basis of the payment obligation and choose the recovery forum with enforcement in mind.

Why International Export Debt Requires a Different Strategy

Cross-border debt collection involves more than proving that an invoice remains unpaid. Even after obtaining a favorable judgment or arbitral award, the exporter must normally enforce it where the buyer or its assets are located.

For this reason, jurisdiction and enforcement strategy should be considered before proceedings are commenced.

Does the CISG Apply to the Sale?

The CISG may govern international sales of goods when its conditions are satisfied. Whether it applies should be determined from the parties’ places of business, applicable private international law rules, contractual provisions and any exclusion or modification of the Convention by the parties.

The exporter should not assume either that the CISG automatically applies to every export contract or that choosing a national law necessarily excludes it.

Check Whether the Contract Excludes the CISG

Parties can exclude or modify the application of the CISG within the Convention’s framework. Review the governing-law clause carefully.

A contract stating that a particular country’s law applies should be analyzed to determine whether the CISG forms part of that country’s applicable sales law.

The Buyer’s Payment Obligation

Where the CISG applies, the buyer’s principal obligations include paying the price and taking delivery as required by the contract and Convention.

If conforming goods were delivered and payment became due, continued non-payment can constitute a breach giving rise to legal remedies.

Start With the Contract

Review the signed agreement, purchase order, order confirmation, general conditions and amendments. Identify the price, currency, due date, payment mechanism, delivery terms, inspection provisions, warranty rules, dispute-resolution clause and governing law.

Do not commence proceedings based only on an invoice if a more detailed contractual framework exists.

Preserve Evidence of the Order

Keep purchase orders, emails, electronic-platform orders and messages demonstrating what the buyer requested.

Where no traditional signed contract exists, the parties’ communications and commercial conduct may become particularly important.

Prove Delivery of the Goods

The exporter should organize transport documents, delivery records, customs export declarations, bills of lading, airway bills, CMR documents where relevant, warehouse records and evidence that the buyer obtained the goods.

A buyer may defend a payment claim by alleging non-delivery or incomplete delivery.

Incoterms Can Affect the Dispute

If the contract incorporates an Incoterms rule, determine what it says about delivery, risk and allocation of transportation obligations.

Incoterms should not automatically be treated as determining every question concerning ownership, payment or governing law.

Collect the Commercial Invoices

Prepare a schedule identifying each invoice, date, amount, currency, due date, shipment and outstanding balance.

For multiple transactions, a clear debt ledger can significantly simplify the case.

Reconcile Payments Already Received

Check bank statements carefully. Identify deposits, partial payments, credits, rebates and set-offs claimed by the buyer.

The amount demanded should be mathematically defensible.

Buyer’s Acknowledgment of Debt Can Be Powerful Evidence

Emails or messages such as “we will pay next week” or requests for additional time may help establish that the buyer recognized the debt.

Preserve the original electronic records rather than relying only on screenshots.

What If the Buyer Claims the Goods Were Defective?

A quality allegation does not automatically eliminate the payment obligation. Examine what defect is alleged, when it was discovered, whether the goods were inspected and when notice was given.

Under a CISG analysis, timely examination and notice of alleged non-conformity can become important.

Request Details of the Alleged Defect

Ask the buyer to identify the affected goods, batch numbers, quantities, technical defect and supporting evidence.

A general statement that the goods were “poor quality” should be distinguished from a properly documented non-conformity claim.

Preserve Pre-Shipment Quality Evidence

Inspection reports, laboratory results, photographs, certificates and quality-control records may become central to the exporter’s defense against a refusal to pay.

Manufacturer records should be preserved before personnel or systems change.

What If the Buyer Sold the Goods to Its Own Customers?

Evidence that the buyer accepted, used or resold the goods may become relevant to the factual dispute, particularly where the buyer later alleges total rejection.

The precise legal consequences remain dependent on the contract and governing law.

Late Delivery Claims Should Be Examined Separately

If the buyer claims that shipment was late, compare the contractual delivery date with actual dispatch and delivery records.

Determine whether the buyer accepted the goods despite the alleged delay and whether it suffered a legally recoverable loss.

Set-Off Claims Require Evidence

A buyer may attempt to deduct alleged damages, marketing costs, customer claims or penalties from the invoice.

The exporter should require a clear contractual and evidentiary basis for each deduction.

Send a Formal Payment Demand

Once the debt and defenses have been reviewed, a structured demand should identify the contract, invoices, deliveries, outstanding principal and payment deadline.

The demand should also preserve the exporter’s rights to interest, damages and legal proceedings where applicable.

Avoid Endless Informal Extensions

Repeated promises that payment will arrive “next week” can consume valuable time.

If an extension is commercially justified, document the new deadline and make clear whether the underlying debt is acknowledged.

Consider a Written Debt Acknowledgment

Where the buyer requests installments, a written settlement or acknowledgment may strengthen the exporter’s position.

It should address the admitted principal, currency, installment dates, interest, default consequences and dispute resolution.

Interest May Be Recoverable

The CISG recognizes entitlement to interest where a party fails to pay the price or another sum in arrears. However, determining the applicable interest rate can require additional legal analysis because the Convention itself does not establish a universal numerical rate.

The exporter should therefore avoid inserting an arbitrary rate into its demand without reviewing the contract and applicable law.

Can the Exporter Claim Additional Damages?

Potentially. Subject to the governing legal framework, recoverable loss may extend beyond the invoice principal.

The exporter should preserve evidence of financial loss and mitigation efforts rather than relying on estimated figures.

Can the Contract Be Terminated?

Non-payment can potentially support avoidance or termination in sufficiently serious circumstances, depending on the governing legal framework and facts.

Termination should not be declared casually because an ineffective termination can create additional contractual disputes.

Additional Time for Performance May Matter

Under the CISG, mechanisms involving an additional reasonable period for performance can be important in certain breach situations.

The wording and timing of notices should therefore be planned carefully.

Stop Further Shipments When Appropriate

If substantial invoices remain unpaid, the exporter should evaluate whether it is commercially and legally appropriate to continue delivering further goods.

Continuing to increase unsecured exposure can transform a manageable debt into a major loss.

Review Suspension Rights

Where the buyer’s ability or willingness to perform becomes seriously doubtful, available contractual and CISG remedies concerning future performance should be examined.

The exporter should document the facts supporting any suspension decision.

Check the Dispute Resolution Clause

Before suing, determine whether the contract requires litigation or arbitration.

A clause may specify a particular national court, arbitral institution, seat of arbitration or procedural mechanism.

Do Not File in Turkey Automatically

The fact that the seller is Turkish does not necessarily mean Turkish courts have jurisdiction over every international sales dispute.

Jurisdiction should be analyzed before proceedings are filed.

Arbitration Can Be Important in Cross-Border Recovery

Where a valid arbitration agreement exists, the exporter may need to pursue the debt through arbitration rather than ordinary courts.

One major strategic consideration is whether the resulting award can be effectively enforced where the buyer’s assets are located.

Foreign Court Litigation May Be More Efficient in Some Cases

If the buyer and all significant assets are located in one country, proceedings there may sometimes provide a more direct route to enforcement.

The cost, duration, interim remedies and enforceability should be compared before selecting the forum.

Asset Investigation Should Begin Early

A legal victory against an insolvent shell company may have little commercial value.

Investigate the buyer’s operating status, assets, subsidiaries, receivables and signs of financial distress to the extent lawfully possible.

Watch for Asset Dissipation

If the buyer appears to be transferring assets or preparing for insolvency, urgent protective measures may need to be considered in the jurisdiction where assets are located.

The requirements for attachment, freezing or similar measures vary considerably between countries.

Insolvency Changes the Strategy

If the overseas buyer enters insolvency, bankruptcy or restructuring, ordinary collection proceedings may no longer be the primary remedy.

The exporter may need to register its claim within strict foreign insolvency deadlines.

Retention of Title Should Be Examined

If the contract contains a retention-of-title clause, determine whether it is valid and enforceable under the law of the jurisdiction where the goods are located.

Its effectiveness can vary significantly between countries.

Documentary Sales Require Special Analysis

Where payment was supposed to occur through a letter of credit, documentary collection or another banking mechanism, determine whether the dispute is actually with the buyer, issuing bank, confirming bank or another participant.

Document discrepancies should be examined immediately.

Letter of Credit Disputes Are Different From Ordinary Debt Claims

A bank’s payment obligation under a documentary credit can be legally distinct from the underlying sale contract.

The exporter should not treat a rejected documentary presentation merely as an unpaid commercial invoice.

Currency Risk Should Be Considered

A debt denominated in foreign currency can change substantially in economic value during lengthy litigation.

The claim should clearly identify the contractual currency and applicable rules concerning interest and conversion.

Limitation Periods Must Be Checked

International sales claims may be subject to limitation rules arising from applicable national law or another relevant international framework.

Do not assume that an unpaid invoice can be pursued indefinitely.

Foreign Judgment Enforcement Should Be Planned Before Litigation

If proceedings are brought in Turkey but the buyer’s assets are abroad, determine whether a Turkish judgment can be recognized and enforced in the relevant foreign jurisdiction.

This question should be considered before—not after—the lawsuit.

Enforcement of a Foreign Judgment in Turkey

The reverse may also become relevant where proceedings occur abroad but the debtor has assets in Turkey.

Recognition and enforcement requirements should be analyzed according to the applicable Turkish framework and the nature of the foreign decision.

Arbitral Award Enforcement Should Also Be Planned

Where arbitration applies, consider where enforcement is likely to occur and whether the relevant jurisdiction participates in the international framework for recognition and enforcement of arbitral awards.

Asset location remains essential.

Evidence From WhatsApp and Email Should Be Preserved

International commercial relationships are frequently conducted through electronic communications.

Exporters should preserve original messages, email headers, attachments and business records rather than deleting communications after extracting screenshots.

Verify Who Made the Statements

A message is more useful when the identity and authority of the person communicating for the buyer can be established.

Preserve corporate email addresses, signatures and surrounding correspondence.

Beware of Fraudulent Buyers

Where non-payment appears connected with false corporate identities, fake bank confirmations or intentional deception from the beginning, the matter may extend beyond an ordinary contractual debt dispute.

Civil recovery and potential criminal issues should then be evaluated separately in the relevant jurisdictions.

Review Trade Credit Insurance

If the exporter has trade credit or export receivables insurance, notify the insurer promptly.

Policy deadlines and collection-control provisions can affect coverage.

Turkish Exporter Should Mitigate Losses

The seller should take commercially reasonable steps to prevent avoidable losses where required by the applicable legal framework.

This may include stopping additional shipments, preserving returned goods or seeking alternative buyers where appropriate.

Keep Contractual and Customs Evidence Together

The recovery file should include the contract, purchase orders, invoices, export declarations, transportation documents, delivery evidence, bank records, quality documents and communications.

Fragmented records make cross-border litigation more expensive.

Prepare a Debt Recovery Matrix

For multiple unpaid shipments, list each invoice, shipment, due date, delivery evidence, buyer objection, payment received and balance.

This allows the legal strategy to distinguish undisputed debt from contested transactions.

Settlement Can Be Commercially Sensible

A negotiated settlement may produce faster recovery than lengthy international proceedings, particularly where the buyer acknowledges the principal but has temporary liquidity problems.

However, settlement should be documented properly and should not unintentionally waive valuable rights.

Do Not Accept an Unsecured Long Payment Plan Automatically

If the buyer requests substantial additional time, consider guarantees, security, acknowledgments or other lawful protection.

The objective is to avoid replacing an overdue receivable with an equally unsecured future promise.

2026 Practical Debt Recovery Strategy

For Turkish exporters in 2026, international debt recovery should combine contract analysis with enforcement planning. The exporter should first confirm the outstanding debt and evidence of delivery, determine whether the CISG applies, evaluate the buyer’s defenses, identify jurisdiction or arbitration requirements and investigate where enforceable assets exist. Only then should the company choose between a formal demand, negotiated settlement, litigation, arbitration or urgent protective measures.

Frequently Asked Questions

Does the CISG apply automatically when a Turkish company exports goods abroad?

Not in every transaction. Its application depends on the parties’ places of business, applicable legal framework and whether the Convention has been validly excluded or modified.

Can an overseas buyer refuse payment merely by claiming that the goods were defective?

Not automatically. The contractual and CISG requirements concerning conformity, inspection, notice and remedies should be examined.

Can the Turkish exporter claim interest?

Potentially. Where the CISG applies, interest may be available on sums in arrears, although determination of the applicable rate requires separate analysis.

Should the exporter sue in Turkey?

Not automatically. Jurisdiction, the dispute-resolution clause and location of the buyer’s assets should be examined first.

What if the contract contains an arbitration clause?

A valid arbitration agreement may require the exporter to pursue the claim through arbitration rather than ordinary court litigation.

Can WhatsApp messages prove that the buyer acknowledged the debt?

They can potentially provide important evidence, particularly when authenticity, identity and context can be established.

What if the buyer has become insolvent?

The exporter may need to participate in the foreign insolvency process and comply with applicable claim-registration deadlines.

Can a Turkish judgment be enforced against assets abroad?

Potentially, but recognition and enforcement depend on the law of the country where enforcement is sought. This should be analyzed before commencing proceedings.

Should further shipments continue while invoices remain unpaid?

The exporter should carefully evaluate contractual obligations and available suspension rights before increasing its exposure.

What should the exporter do first?

Secure the contract, invoices, delivery evidence, bank records and buyer communications; calculate the exact outstanding debt; determine whether the CISG applies; identify the correct court or arbitration forum; and locate the buyer’s assets before selecting the recovery procedure.
