Legal Effect of an Acknowledgment of Debt

Legal Article · 12 November 2026
Av. Thomas Andreas Di Constantinople

Acknowledgment of debt is a person's declaration that a particular obligation exists. Article 18 of the Turkish Code of Obligations permits its validity even without stating the cause in the document. This does not mean the document invariably creates an indisputable debt or waives every debtor defence.

The declaration's content, relevant debt, and legal nature of the intention must be identified. A payment plan, account reconciliation, or correspondence may contain acknowledgment according to context; an unclear invitation to discuss may not have the same effect. Acknowledgment must not be confused with settlement, novation, or release agreements.

One important consequence concerns limitation. Under Article 154 of the Turkish Code of Obligations, a debtor's acknowledgment interrupts limitation. The statute also lists conduct such as partial payment or payment of interest. Identifying which debt the action concerns is important to interruption.

A new period begins upon interruption; acknowledgment by instrument requires consideration of the special period in Article 156 of the Turkish Code of Obligations. Article 19 also limits a simulation defence against a third party acquiring the claim in reliance on written acknowledgment. Acknowledgment must therefore be assessed as a transaction with substantive-law consequences, rather than merely evidentiary documentation.

Legal Basis: Turkish Code of Obligations No. 6098, Articles 18, 19, 154, and 156. Official legislative text.
