Legal analysis: the registration items on the marriage certificate should be complete. If the marriage registrar forgets to sign and stamp, it is an invalid certificate, and he can find the marriage registration office at that time to renew or reissue it. The marriage registration office keeps records, and the original files can be retrieved to prove whether there is a marriage relationship. According to the relevant laws and regulations, the marriage certificate must be signed by the marriage registrar who approved the marriage registration with black ink pen or signature pen.
