How old do you have to be intill you can chose witch parent you want to live with

She wantsto be emancipated but it's a different process in different states. SO where does she live?

The decision to file a change of custody lies with your friends father, not the child. Most courts will take a child’s wishes under advisement, but the child’s wishes are not determinative, nor does the court have to consider them at all. Perhaps, since the father has not objected to the relocation, he believes that your friend is better off with the mother, or he not prepared to offer full time care to his daughter. There is much to be said for the overseas experience, and continuing the bond with the half -siblings. Though the father has the legal right to object, and a “move away” is sometimes grounds for a change of custody. In most states the custodial parent cannot move away from the other parent without court approval, as there is a “parenting plan “ ( visitation ) for the non custodial parent. For the custodial parent to move away without the courts consent will put the custodial parent in contempt of court. Explain this to your friend and have her consult her father about bringing a court action.
