Yes, he will need their permission. Or have to get a court order. Until the minor turns 18, the guardians are responsible.
If your father have visitation right or share custody she will need his permission.
It is illegal.
If there is a visitation order or you share custody you will need his and the courts permission to move.
Yes, you cannot move out until you are 18 without parental permission.
Only if he has custody or visitation rights with her. Otherwise, no.
Yes, you can. However you need your father's permission too if he's your guardian.
That will depend on whether paternity has been established. If the mother is not married at, or within 300 day of the birth of the child, there is no legal father unless through the court. In that case, no one's permission is needed, however the father may bring suit himself. Under those circumstances, many courts will see allowing the move is in the best interest of the child. If there already is a court order in place, you need the court's permission, not the father's permission for the move.
If she is virgin then yes, she needs the permission of her father or paternal grandfather. If she is NOT virgin, then she does not need the permission of her father or paternal grandfather.
If there is a custody agreement in place that allows the father any access to his child other than supervised visitation then most likely yes the mother will need the father's permission to move the child out of the current country of residence.
If you are below 18 you will need one or both parents or guardians consent and in some cases also the courts permission. The laws vary between states.
Provided that the mother still lives in the state of current jurisdiction, he will need her permission, or the permission of the courts. Plus, access rights will need to be renegotiated. See below for an example of an order I teach father to use when a mother wants to move away with the kids.
Yes, as he can still file an injunction to stop it pending a court hearing, which I teach them to do. see link
