The basic process for reissuing the marriage certificate: first, I need to hold the household registration book, and also take the recent bareheaded half length group photo of two people, which requires two inches and three pieces. I need to apply for reissuing the ID card to the original marriage registration authority, or the marriage registration office where one party's household registration is located, and fill in the declaration form for applying for the acquired marriage registration certificate on the spot. The marriage registration authority shall verify the marriage registration files of the parties concerned, and if it is verified, it will reissue the marriage certificate on the spot. If there is no marriage registration file or the applicant's marriage registration file cannot be found, the applicant needs to submit other materials that can prove the marital relationship, such as the certificate of marital status issued by the unit village committee neighborhood committee.
