You should just file for sole custody of your child. If the father is in jail and he is not on the birth certificate then he would have to prove that he was the father by taking a partentily test when he gets out of jail. But it is smart to get sole custody so that you don't ever have to have this hanging over your head down the road. When you file for custody you need to also file for child support,you have that right and you do not have to prove that he is the father. When he gets out he will have to get a job and pay you back child support. If you do not file for child support you will not be able to file after he gets out and exspect him to pay any back payments because the law now states that you have to file to recieve child support and if you don't then you will only get child support when you file later down the road and you won't be able to file for any back support unless it has already be ordered though the court.
