Legal Question in Family Law in California

You basically have two options: open a claim with the Dept. of Child Support Services, or hire an attorney to file a contempt proceeding against him. The first option is free, and may or may not be successful, depending primarily on whether or not he has any meaningful assets (income is irrelevant) that can be easily found (such as stocks or real property). They don't have the staff to hunt down hidden assets in most cases. The second option, of course, costs money, and it is illegal to take a family law case on contingency. It is the only way, however, to have a serious chance of tracing hidden money to him.
