My sister is 17 (just turned) and has been visiting with my mother for the summer. Her father lives in another state and has been caring for my sister for the last two years. He abandoned my sister and mother when my sister was 10. My mothers health is failing so my mother asked for my sistes father to take custody two years ago. It is now coming time for my sister to return to her father and he has proclaimed he does not want her to be returned to him. I think this is awful and I feel sad for my sister. My mother is living with bad health and cannot take care of my sister properly. My question is, can I file for temporary custody of my sister and would I be able to receive some child custody from the father? I am on a limited income but Iwant to do the right thing.
