If I have joint 50/50 custody of my kids with my ex-wife should I still be paying child support? I have been ordered to pay $640 a month for child support for my two kids plus I have to pay their health insurance which is an additional $250 a month. Does this make sense. The court is ordering me to pay about 43% of my gross income a month. I can't afford this. Meanwhile the mother has to pay nothing. We make about the same amount of money plus she doesn't have to pay rent because she is the manager at her apartment complex. I don't know what to do. The judge just tells me "oh well" Can someone tell me if what the court is doing is even legal? Any advice would be greatful. Thanks
