The household registration books of children and parents are not on the same household registration book. How can I prove kinship?

When proving kinship, it is generally divided into two situations:

1. Both parties whose household registration is proved belong to the jurisdiction of the same police station. You can bring your household registration book and birth medical certificate to the local police station to prove kinship.

2. The domicile of both parties to the proved relationship is not under the jurisdiction of the same police station. You should bring your household registration book and your family's household registration book to the police station where your household registration is located, and ask them to help you check the original registered address, and then the original registered police station will issue a certificate of kinship.
