It depends where you live.
If you have custody and the father keeps the child with him without your permission you can call the police for kidnapping.
not without permission
yes if she has full custody
no, it requires the permission of the court.
While pregnant she can move anywhere she wants and doesn't need the father's permission. However, once the child is born it's a simple matter for the father to request a court order requiring her to return the child to the state. And if the court feels that she moved merely in an effort to deny the father his rights to the child, they will not view that favorably.
Single father? No see link below
yes he can.
With parents permission. Having a baby at 15 doesn't make you an adult. You are a minor that is pregnant.
If there is a court order for custody, visitation or child support she will need his permission. See related question link.
The father may take the child if and only if the child is not safe where it is and is happy to go with the father. You could leave a note and make sure that you leave a contact for the mother. Otherwise you may not. However the mother may not take the child from the father withot permission either. If you were to do this without good reason then it could be held against oyu in the court of law.
Divorce is something that happens between spouses, not between parents and children. A child's refusal to see the father does not affect the father's child support obligation.
sorry but not with out a court order saying you can with out his permission
