A debt subscription is a separate document containing a statement of the existence of a debt that the debtor issues to the creditor. It most often takes the form of recognition if it contains an indication of the reason and the amount of the debt, but it can also be another written confirmation of the claim. The debt subscription thus confirms an existing obligation arising from a previous contract, mostly a loan of money. In the case of debt recognition, the issuance of a debt subscription has substantive consequences (the limitation period is interrupted and a new, ten-year limitation period begins to run) as well as procedural (rebuttable legal presumption that the debt lasted at the time of recognition in court proceedings to prove the debtor). If the creditor issues the debit note to the debtor without the debt being fulfilled and without at the same time issuing him an acknowledgment, he expresses the debt forgiveness. On the contrary, if the debtor fulfills the debt, he has the right to return the debt subscription according to § 1952 of the Civil Code. If this is not possible, the creditor will issue him a confirmation that the debt subscription has expired.
