Child support isn’t alimony. I don’t think anyone begrudges the parent who has primary custody of the kids, getting child support from the other parent.
Of course not all parents who get child support use it for child support.
Why didn’t the state wher you live go after this guys’ wages and garnish, or go after his bank accounts? They do that all the time.
He works, they find him and start the collection process, he finds out about it and quits. He won’t hold a job unless it’s “under the table” pay...that way, he doesn’t have to pay. He doesn’t file taxes either since they would seize that...the first 4 years, he filed and claimed the kids’ EIC...taking about $7000 a year from the government that he wasn’t due.
Now he’s married to a convicted/registered sex offender. She gets disability because of the conviction. They live off that, and a paper route that pays unreported cash. (the last I heard anyway)
