Yes, but only if the birth father's parental rights have been terminated by the courts.
This depends on where you live. And no, I think he has to give up his parental rights.
Only if the court has taken her parental rights away or she have given them up to the state, can that happen. Then it's the state that decides who will adopt the child. If she has her parental rights you can not adopt without hers and the fathers consent.
absolutely not, no one can adopt any one without the proper court orders
If a biological parent gives up their parental rights, then the spouse of the other parent is able to adopt the child. The parent who gave up their rights has no say in the matter.
now a stepfather can't adopt a child without the concent of the child's father
Yes. Go to a lawyer. He/She will discuss it more further.
no, she must approve
No a stepparent can only adopt if the birth father or mother relinquishes their parental right of the child.
Then unless the biological father is ok with this and signs his rights over, the new husband has no legal rights to the child.
Only if the court suspended the parental rights.
No
Only if you live in Utah, there notification is enough. You can go to court and see if you can get his parental rights terminated.
