CCQ-1991 - Civil Code of Québec

2834. A release, although unsigned and undated, inscribed by a creditor on the title of his debt or on a copy thereof which has always remained in his possession makes proof against him.
The release is not admissible in proof of payment, however, if it has the effect of withdrawing the debt from the rules governing prescription.
