According to the information of China Law Network, the handwritten agreement or commitment of the other party requires that the application for household registration transfer should be based on the handprint, which is also the requirement for applying for household registration transfer. If it is signed by the other party, it will have more legal effect.

The transfer of children's household registration generally requires parents' household registration book, ID card, marriage certificate, children's birth certificate and birth certificate to settle in the police station.
