Have your attorney check into this law, if the man was making that much money and not paying child support then he looks to be "willingly" not paying. Refer to section below of $10,000 being a felony. Check your state OCSE to find out how they handle someone who is $10,000 or more behind in C/S. Some will have him sign an agreement and if he misses ONE TIME then he goes to prison- not jail but prison. hope this helps.
