I have sole custody of my 6 year old daughter. Her biologicial father has visitation rights but really doesn't want anything to with her. He has only seen her 5 times in the last 6 years. I have been with a man since she was 2 months old so she calls him daddy. She knows of her father, but doesn't know him. If I were to die and left a noterized paper stating I wanted my custody to go to the only man she knows as daddy(we also have two other daughters together)because her father is a homeless drug addict would that be able to happen? How would I go about making sure that he does not get custody, because he can not take care of his self let alone my child. Please help me!
