Can family members get custody of a child because they do not want the child's parent to move to another state?

If the parents want to move, the girl must go with them unless she is 18. If she is old enough and responsible, some parents let their kids live with a trusted family until they finish high school - but that is totally up to the parents because they are legally responsible for their kids. Another family cannot get custody of a girl just because they don't want her to move. A judge won't take a biological daughter away from the family for a stupid reason like that. If the girl is abused, neglected or just just lives with her friends, they have a better chance of attaining custody.
