I have a 4-year-old son and his father has never wanted him since I was pregnant and he's never paid child support or seen his son. He also claimed he wasn't the father and we did a dna test and the results came 99.9%. Earlier this year, I finally claimed child support but he has been complicating the whole process. He wouldn't sign the statutory declaration forms and now we have to go to family court. My question is: 1. Will he get shared custody of children even though he's never been in the child's life? 2.How far along will the backdate the child support?
