D) changing the type of Promissory Note
Article 650 – (1) a written deed of Nama or order can only be converted into a pregnant written deed with the consent of all persons to whom it is entitled and burdened with debt. This consent must be written directly on the promissory note.
(2) the same rule applies to the conversion of pregnant written promissory notes to nama or order in a written Year. If in this last case the consent of one of the persons who have rights or debts is not found, this conversion refers only to the provision between the creditor who made the conversion and the person who directly successor to his rights.
