As an added afterthought, it doesn't make a wit's bit of difference if by some chance he gets disability because he still has to pay child support.
Amber's dad ran his own little trucking company, and since he claimed that his work was spotty, the support was based on him making minimum wage at 40 hours a week. I don't know if it differs from state to state.
Now when he was taken to court for an increase when she was 11, that's when my attorney discovered that not only was he drawing a substantial amount from disability insurance he bought as he was home recuperating from a work-related shoulder surgery, but he also had a huge chunk of change he collected in interest off of the trust fund his parents left him every year.
Your EXAH is nuts if he thinks he's exempt from child support.
