Not if he filed for a change, as he should have.
A father can get custody of the children if it can be demonstrated that that is in the best interest of the child. The father being the primary caregiver would help.
No. Your parents must come to an agreement and change the custody order filed in the family court.
Get can't without the permission of the court. File an injunction.
You still must have permission of the father. There are a few states where if you're been denying the father access to the child for six months or more, the permission is not needed.
The father was awarded custody of his children.
Yes you can. The legal guardian decides.
You have the visitation rights that were established in the divorce, and you have no custody rights.
Guardianship, not custody
If your father have visitation right or share custody she will need his permission.
Not without his fathers and the courts permission.
It depends on the custody agreement that is in place. If a minor changes residence without the permission of the parent who has primary custody, then that goes against the court order. If she wants to change residences, a request to the court will usually accomplish this.
A mother has sole rights to her children unless/until a court order is issued giving the father custodial rights. If there is not a custody order from the court the unmarried mother may take the child/children and move whenever, wherever she wants.
