It depends on which State you are in, and other variables of the minor the Civil judge has to consider. Often around age 15.
If the parents are divorced then it is between the parents if the child can go live with the other parent. At age 14 the child can choose witch parent he/she wont's to live with. If that other parent is not willing to let the child go live with that parent then it can be taken to court or just wait till the child is 18 and can go live on it's own.
