Contact your State's child support enforcement agency - they can require that he look for work. Be patient but persistent. Good luck!

Most likely. Just about every state will intercept federal and state income tax refunds for child support arrears.

Not currently. see links below
There's no "get out of child support free" card for having more than 12 children. That would be ludicrous: a divorced spouse caring for 12 children obviously has a greater need for child support than one with only one or two.

Do you have an Office of Recovery Services or Child Support office where the child lives? My sister's ex worked for a company who paid him in cash but RS told his boss that if he didn't take out child support then they would go after him. It is different in each state.
