Is $11,516.00 a lot to be behind in child support payments? My daughter is 3, case has only been open for 3 years. When I call the enforcement office they never answer the phone or do anything to help collect. They've suspended his license in the state I live in (he lives the next state over) but I don't know what else can be done to make him pay up. He works full time, lives at home, has a nice truck, doesn't see his daughter or help support her. I'm at a dead end.
