I have a baby by a man who is married. He has 3 kids with wife and another child with someone else. I believe he is paying child suppport to the other woman. He knows I have a child by him but acts as if I do not. I am not receiving any money from him. I want to file for child support but I do not want him in return to file for any type of custody of my baby. My baby is young and I do not trust him or his wife. His wife does not know about me. Would I be able to get much child support from him and does he have any chance of getting any type of custody?
