Turkish Customer Claims Goods Were Defective to Avoid Payment: Legal Remedies for Foreign Sellers – 2026 Updated Guide

Defective Goods Dispute in Turkey | Foreign Seller Remedies

Learn how foreign sellers can challenge false defective-goods claims in Turkey, prove delivery and quality, recover payment and protect commercial rights.

A Turkish customer may claim that delivered goods were defective after the payment deadline has passed. Sometimes the complaint concerns a genuine warranty issue. In other cases, it may be used as a pretext to delay or avoid payment.

A foreign seller should not immediately accept the customer’s allegations or cancel the invoice. The seller should examine the contract, delivery records, inspection process, defect notice and the customer’s conduct after delivery.

This 2026 updated guide explains the legal remedies available to foreign sellers when a Turkish customer claims that goods were defective to avoid payment.

Does a Defect Claim Automatically Eliminate the Payment Obligation?

No. A customer’s allegation does not automatically cancel the invoice or eliminate the seller’s right to payment.

The legal effect depends on whether the goods actually failed to comply with the agreed specifications, whether the customer inspected them, whether the defect was reported on time and whether the alleged defect affects all or only part of the delivery.

The customer may have remedies such as repair, replacement, price reduction, return or damages where a genuine defect is proven. However, an unsupported complaint does not necessarily justify withholding the entire purchase price.

What Should the Foreign Seller Check First?

The seller should review the purchase order, specifications, warranty terms, inspection clause, delivery conditions, limitation provisions and applicable jurisdiction or arbitration clause.

The seller should then determine when the goods were delivered, who accepted them, whether any reservation was made and when the customer first reported the alleged defect.

A complaint made only after several payment reminders may be relevant, particularly if the customer previously accepted the goods or used them without raising an issue.

How Can Delivery and Acceptance Be Proven?

Delivery may be established through signed delivery notes, carrier records, warehouse documents, customs records, transport documents, photographs and customer acceptance certificates.

The identity and authority of the person who accepted the goods should also be examined. If the customer’s employee signed the documents, the company may still be bound depending on the circumstances and prior commercial practice.

Use, resale, installation or incorporation of the goods into another product may support the seller’s argument that the customer accepted delivery. These facts do not automatically defeat a hidden-defect claim, but they may weaken a late or general objection.

What Evidence Is Needed to Challenge a False Defect Allegation?

The foreign seller should preserve product specifications, quality certificates, inspection reports, production records, photographs, serial numbers, packaging information and pre-shipment testing.

The seller should also collect communications showing that the customer approved samples, accepted delivery, used the goods or promised payment after receiving them.

Independent laboratory reports, technical expert opinions and evidence from other customers may help demonstrate that the goods complied with the agreed standards.

Did the Customer Give Timely Notice of the Defect?

The timing and content of the customer’s notice can be important. The customer should normally identify the alleged defect with sufficient detail and comply with applicable contractual or statutory notification requirements.

A vague statement such as “the goods are defective” may not explain the problem, affected quantity or requested remedy. The seller should request photographs, inspection reports, serial numbers and a detailed technical explanation.

Short notice periods may apply to certain commercial sales. The contract and transaction type should therefore be reviewed immediately.

Can the Seller Request an Independent Inspection?

Yes. An independent inspection may clarify whether the goods were defective at delivery, damaged during transportation, incorrectly stored or misused by the customer.

The seller should request that the goods be preserved and not repaired, altered, resold or destroyed before examination. If the customer refuses inspection, that refusal should be documented.

Where evidence may disappear, the seller may consider a formal evidence-preservation or judicial examination procedure.

What If the Goods Were Damaged After Delivery?

The seller may not be responsible for damage caused by incorrect storage, installation, transportation after delivery, misuse or unauthorized modification.

The applicable delivery terms and risk-transfer provisions should be examined. Transport records, packaging photographs, temperature records, warehouse conditions and installation documents may be relevant.

The customer’s handling of the goods should be compared with the manufacturer’s instructions and the contract.

Can the Seller Recover Payment Through Enforcement?

If the invoice is due and supported by delivery and contract evidence, the foreign seller may be able to begin a monetary enforcement proceeding in Turkey.

The Turkish customer may object by claiming defective goods, non-conformity or failure of performance. If an objection is filed, the enforcement process may be suspended or become contested.

The seller may then need to challenge the objection or file a commercial lawsuit seeking payment. The defect evidence should be prepared before or alongside the enforcement strategy.

Can the Seller File a Commercial Lawsuit?

A commercial lawsuit may be appropriate where the customer disputes the quality, quantity, delivery or conformity of the goods.

The seller may seek payment of the principal, contractual interest, default interest, damages and collection costs where legally available. A technical or accounting expert may be appointed to examine the goods, invoices and delivery records.

For certain commercial monetary claims, pre-litigation mediation may be mandatory. The contract’s jurisdiction or arbitration clause should also be reviewed.

Can a Provisional Attachment Be Requested?

A foreign seller may consider provisional attachment where there is a due monetary claim and a risk that collection will become difficult.

The request may concern the customer’s bank accounts, real estate, vehicles, shares, inventory or receivables from third parties. A court may require security before granting protection.

A provisional attachment does not prove that the goods were conforming, but it can preserve assets while the payment dispute is being resolved.

What If the Customer Demands a Refund or Replacement?

The customer’s requested remedy should be compared with the nature and seriousness of the alleged defect.

A minor issue may not justify refusing payment for the entire shipment. If only part of the goods is affected, the dispute may concern a partial price reduction, replacement or repair rather than total non-payment.

The seller should avoid agreeing to a refund, replacement or credit note before verifying the defect and preserving its legal position.

What Evidence Is Important in 2026?

In 2026, electronic purchase orders, customer portal records, inspection photographs, electronic invoices, emails, WhatsApp messages and digital logistics data may be decisive.

The foreign seller should preserve original files, complete message chains, delivery confirmations, technical reports and metadata. Screenshots alone may be challenged.

If the goods are technical, perishable or easily altered, the seller should act quickly to preserve samples and obtain an expert examination.

Can a Foreign Seller Act from Abroad?

A foreign seller does not always need to travel to Turkey. A Turkish lawyer may act under a power of attorney issued before a Turkish consulate or a local notary.

Depending on the issuing country, legalization, apostille and official translation may be required. Foreign technical reports and corporate documents may also need translation and certification.
