I recently went to court for child custody and child support, the gave me and my ex joint custody and due to we have 2 girls he has to pay 25 % from what he makes. But since we split up back in 2007, i wanted all that back pay due to he was never there for my girls. The judge decided it was on that past, so he doesnt has to pay that back pay. How can i do to get all that back pay?
