Your first stop should be Child Protective Services. They are going to have significant input to the judge when a decision is made. They will want to know you have a stable financial and housing situation.
you get it for her.
No. The biological father have rights. Unless the court find him unfit to have custody then there might be a chance.
you bet. becoming 18 gives the "adult" permission to live wherever he/she wants. he/she is nobody's custody.
Generally, custody orders end at age eighteen and the child can choose where she wants to live.
If the son wants to I believe he can. In my state (Georgia) the child can choose who he/she wants to live with at the age of 14.
What I would suggest is to not FORCE him to pay, but at least TRY to TALK HIM INTO IT.
If you have Joint Legal Custody, then neither parent can physically change residences without the approval of the other. If, per the question, the daughter is living with the father, or the father has "primary" custody, then you can move wherever "you" want, at least in my perception.
He can still file an injunction
No, legally a minor has no choice in the matter.
If you choose to let her.
Why is Daughter living with Father if Mom has custody? I'm wondering why Dad hasn't already petitioned the court for custody. He certainly can do that, and since Daughter is already living with him anyway, he'll likely get it. Basically as long as Daughter lives in Dad's house, he can set any rules he wants to--including the rule of not dating adults. If Daughter refuses to follow Dad's rules, she may find herself being sent back to live with Mom in PA--which would be a long way from Boyfriend.
no, but the father could file for custody see links below
