1. First of all, husband and wife should negotiate and reach an agreement on the issue of changing their children's surnames.
2. Then, submit a written application to the household registration authority and fill in the application form for change registration.
3. Then, the household registration authority will review the application and change the name of the child.
4. Finally, according to the needs, the applicant needs to provide relevant information, such as household registration book, resident ID card, consent certificate of work unit or neighborhood Committee, written report of parents' consent to change, birth certificate, parents' marriage certificate, etc.
It should be noted that if the other party does not agree to change the child's name, it is not allowed to change it without authorization. At the same time, adults can directly apply for renaming, and the process is the same as the above process. If you have any questions about your child's name change, I suggest you contact the local household registration authority or the household registration section of the Public Security Bureau for consultation.
