Generally, custody orders end at age eighteen and the child can choose where she wants to live.
No. The biological father have rights. Unless the court find him unfit to have custody then there might be a chance.

If a child's mother has sole custody then the courts have decided this and there is a reason for it. Generally, if the mother is a good mother (fit mother) then the children will be looked after by her with the father having partial custody to see his children. If the father is unfit, then the mother would have full custody. If you are the child asking the question and are upset because your mother has house rules and you don't always agree with them then this is not a good reason to want to live with your father. Your mother gives you these responsibilities so you will learn good characteristics that will make your life a whole lot simpler. You may not see that now, but will in the future. If this is the father asking the question and you have partial custody the courts have deemed it this way for a reason. If the mother is unfit and the father wants to take full custody then you should retain a lawyer asking for full custody.
That depends on the custody order, but she can file for a change of custody.
If you are a father. You must prove the mother unfit, drugs, abuse, prison record, etc... IF you are a mother, depending on the state you live in they would allow soul custody because you are the mother. If the father is unfit and you live in Utah and/or California where they are for the father as well and want to do joint custody in most of those two states, the father must pretty much be unfit such as abuse, drugs and/or prison record for the mother to get full custody. That is pretty much when the only time I have known any parent to get full custody of their children.
It depends on the law where you live and your custody order. If the father has sole legal custody (as opposed to physical custody) he would be able to make that decision without input from the mother. If legal custody is joint or the mother has sole legal custody, no he could not.
If you live in the US... The father's parents have no rights to custody at all. The father has the right to petition for custody, but he won't be given sole custody unless he can prove the mother unfit. He might, however, be given joint custody.
