Incidentally, most courts will "impute" income to a parent who isn't working without good reason. For example, let's say a doctor capable of pulling down $250,000 a year decides to quit and go to work at McDonald's to avoid paying support. The court will impute what he is capable of earning, and figure the child support based on the $250,000 a year, not the six bucks an hour he gets flipping burgers.
