I have a granddaughter that I care very much about, but I'm concerned about her future. Her mother (my daughter) separated from her ex-boyfriend (the child's father) not too long after she was born, due to him becoming abusive and violent. At the time of my granddaughter's birth, though, both parents were still on good terms, so the ex's name is on her birth certificate. After they broke up, my daughter and granddaughter came back to live with me and my wife. The ex stalked my daughter for a month after wards, so she tried to get a restraining order. However, he vacated his old apartment and the authorities could never find him to serve the summons.
My question is this: if something were to happen to my daughter, what would happen to her child? My wife and I worry that she would have to go back to her father, who we know isn't a fit caretaker. Is there anything we or my daughter can do to ensure that my granddaughter can stay with us?
