Ok so I have 3 children of which I have exactly 50/50 custody of, recently I have had them in March for 20 days to 11 days. I pay a lot in child support when their mom is a nurse and makes more then me. The PA Child support calculator is outdated and based on primary and non primary custody. I have a lot of people that I know that do not have to pay since it is 50/50 but I always get stuck. Is there something I can do to fix this?
