I have a friend that is wanting residential custody of his daughter. He is on federal probation. When him and his daughters mother split up she left for about a week or so and did not call or anything. The father went to work and took care of his daughter for this time, now i know this should of been the time to take her to court but he did not. when the mother came back he gave her the child and the child was living with her up until a few days ago when the father took the child because the mother was getting evicted for illegally turning on the water and electricity. The mother is on drugs and has no job. she frequently has no water or electricity. she also lives in a one bedroom dulpex that she does not pay rent at with her boyfriend who also does not have a job, and the daughter does not have a room. She sleeps on the couch most of the time. The father has a good paying job and also has a history of not paying utility bills but can provide a good home with utilities now, with a bedroom for the child. What are the chances of him winning this custody battle.
