What if one party loses its divorce certificate? If one party loses its divorce certificate after divorce, it may apply for a new one. According to Article 17 of the Marriage Registration Regulations, if the marriage certificate or divorce certificate is lost or damaged, the party concerned may apply to the original marriage registration authority or the marriage registration authority of the place where one party's permanent residence is located for a replacement by holding the household register and ID card. The marriage registration authority shall verify the marriage registration files of the parties and, if it is confirmed to be true, shall reissue the marriage certificate and divorce certificate for the parties. Do you understand that?
