If you know that he is not the father of one of the children then know he will not have to pay child support for that child unless he has put his name on the childs birth certificate then he would. The child that is his yes he will have to pay child support so you just need file for child support and also you need to file for custody of your children even though they have different fathers because until it is court oerdered you do not legally have custody. The father is entitled to visitations.
