Is there a possibility that if they go after him, and he files for those ten years, that I will get that money? He admitted in court papers that he hasn't filed since '02, but he obviously has worked because da was garnishing wages for child support.
Child support is a payment made from one parent to another parent (usually from non-custodial to custodial), to help ensure the child's financial needs are met.
Not all states set a statute of limitations on child support. In those that do, the deadline to request support varies widely, lasting 20 years in some states.
