Beg. If all else fails, steal the child
Who legally adopted the child?If the mother's new husband legally adopted the child, then the biological father's parental rights had to be terminated first. Which means that the biological father is NOT obligated to pay child support anymore. The new adoptive father has taken on all rights and responsibilities for the child.
A birthfather is the biological father of an adopted child, or a person's biological father.
No. There is no requirement for the child to have to "know" the father for him to give up his parental rights.
If you legally adopted the child, you would terminate your parental rights the same way you would with a biological child. Get a lawyer and go to court. However, keep in mind that if you legally adopted the child, terminating your parental rights does not terminate your legal relationship with the child. According to the law, you are the child's father and you will be required to pay child support. Terminating your parental rights will only relinquish your custody rights and your ability to make decisions on behalf of the child.
YOUR
no, changing the birth certificate requires adoption, and can only be done if the birth father's parental rights have been terminated.
That is up to the courts and not the adoptive father.
Since a sinlge mother has sole custody by default, this question makes no sense.
If you live in the US (and without knowing the state) generally speaking, adoptive or biological is irrelevant. If there's a will and the child is not named, the child gets nothing, unless they can successfully contest the legality of the will (which takes a strong case).
Termination of parental rights does not terminate child support until/unless the child is adopted. At that time, the biological parent still owes whatever he had been ordered to pay and has not paid.
Yes, both parents do.
[if you're the obligor] Show the court that: you have custody of the child; the child is deceased; the child has been adopted; the child is emancipated; the child has attained majority; and/or you have no income other than public assistance; AND, you do not owe any past-due support.
