Extinguishment of Obligations and Ancillary Rights

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

An obligation may end through proper performance or other statutory grounds. Release, novation, merger of creditor and debtor capacities, impossibility under specified conditions, and set-off are distinct routes. Their requirements and effects differ, so they should not be used interchangeably for one event.

Discharge of an obligation differs from termination of the whole contract or continuing relationship. Payment of one rent instalment does not end the lease. Other contractual obligations and protective duties may continue.

Under Article 131 of the Turkish Code of Obligations, principal discharge generally ends dependent rights such as security, suretyship, interest, and penalties. Reservation of accrued interest and penalty rights by contract or notice until performance, or circumstances indicating reservation, nevertheless matters. Special rules for mortgages, negotiable instruments, and concordat remain.

Payment scope, partial payment, reservations, and third-party rights require separate examination. Return of the debt document or issue of a receipt may affect proof. A new instrument alone, however, does not automatically extinguish the old obligation without express novation intention.
