Passport cost $311k in back child support

[Drolefille]

I know in Illinois it's on the application to get a hunting or fishing license.

There's a section that requires you to attest that you do not owe child support, or something saying that you do. If you check that you do, I don't think you get the license... and they report you. If you check that you don't, and you're caught lying the fine is STEEP. So at the very least it adds an extra penalty onto a deadbeat's back.
