Hello, after parents divorce, when children fill in family members, they usually follow their caregivers to fill in. If the child is awarded to the father, the family members can fill in the newly formed family members. Although it is not recognized in my heart, it is legally effective. If the child is awarded to the mother for support, after remarriage, family members can fill in the newly formed family members. If children don't agree with this, they can also fill in their biological parents, including brothers and sisters, when filling in the family relationship.
