No. As is the case in a typical divorce, both parents have a right to seek custody in a case involving adopted children. Just as adopting a child is an attempt to bring some measure of security, stability and peace into the child's life, the courts in a divorce case will attempt to continue this peace by giving the child contact with both parents. The courts generally hold that this is what is best for children after a divorce or legal separation – unless there is a reason to deny custody to one parent, such as:
Domestic violence
Child neglect or abuse
Child endangerment
Abandonment
Child abduction
Disobeying court orders
A substance abuse disorder
Incarceration
Unless custody or visitation with one parent would endanger the child in some way, the courts will generally create a shared custody agreement. This is the case whether or not the child has been adopted. The California courts view adopted parents as the legal parents of the child. This means that they will be treated like any other parent in a California divorce case. Custody will not go to the child's biological parent in a divorce after the child has been adopted, as the biological parent has given up all parental rights.
