The court will decide how much, usually for one child it is 17% - however, it can be altered on an individual basis - say he carries the child on health insurance and pays 50% of daycare costs.......... the CS payments may be 10% - - - or less..........
My ex and I have 50/50 and we pay 50/50 for all expenses so I get ZERO in child support and he doesn't get anything from me, either......... to me that is the best way........
I don't have the hassel of it, etc.
