this is kind of complicated but here goes. my girlfriend lives with me having moved out of her adoptive mother's house, since then she has worked and went to doctors appointments on her own with no help needed aside from getting a ride there and back. her mother is threatening to come here where we live and take her against her will back to the mother's house....the mother is claiming that she can do this because she has power of attorney over my girlfriend yet refuses to show documents or any other proof...my question is this if she does have power of attorney can she do this?
