text: what is the legal age that you can either leave home or you can choose who you want to live with? i dont mean in a loving relationship, i just mean for a childs guardinship, who will look after them eg the mother or grandmother, when can the child choose, any help would be realy appreicated leaving home is usually 18, but choosing who you want to live with like mom & dad seperated.  the judges really start listening around 14 or so.  you have to go to court for the latter one, and see a judge.
