How to notify the debtor of the execution of creditor's rights transfer

After the creditor's rights are transferred, the debtor can be notified in the following ways: 1. Oral notice. But it is difficult to prove that the debtor was so informed in the future. Second, a written notice. This method is generally applicable to the notification of the transfer of creditor's rights between enterprises. Third, SMS notification. However, as electronic evidence, the retention and fixation of SMS is more complicated than general written notice. Fourth, email notification. In practice, it is best to notify the debtor in writing; If the notice is given in a form other than written form, it shall ensure that the debtor can know the fact of the assignment of creditor's rights in a timely and accurate manner. Article 546 of the Civil Code: If a creditor transfers his creditor's rights without notifying the debtor, the transfer shall not be effective for the debtor. The notice of assignment of creditor's rights shall not be revoked, except with the consent of the transferee. Article 545 A creditor may assign all or part of its creditor's rights to a third person, except in any of the following circumstances: (1) No assignment may be made according to the nature of the creditor's rights; (two) according to the agreement of the parties shall not be transferred; (3) It shall not be transferred according to law. If the parties agree that the non-monetary creditor's rights cannot be transferred, they may not confront a bona fide third party. If the down payment creditor's right is not transferable, it may not be against a third party.
