I had asked a while back about how I could help my sister and I get away from our abusive mother. I managed to get my mother to sign my sister over to me (it basically states that she is under my guardianship from the moment the paper was signed, and on.). I have it notarized. What are the next steps to making it so I could move out of this abusive atmosphere with my sister legally, so I don't have to worry about our mother doing anything about it.
