My son's father and I had an agreement that he would pay our child's daycare and I would take care of other finances for our son. Well, I found out that he was expecting another child and I filed for child support because I knew he would go back on his work. He only pays half the daycare now. Once I filed for child support, he petitioned for legitimation. Now the Office of Child Support has rescheduled our Child Support hearing twice due to the pending legitimation hearing. Is this legal? I was told by the Office of Child Support and my attorney that these were two separate cases. Please advise.Once his child support amount is decided, will he have to pay arrears?
