Here, they base it on income and there is amount ordered even if the parent is unemployed. I was unemployed but "had the potential to make more", so they based my amount as if I was working at min. wage. Now, difficult child's father is married (apparently as of just a few months ago). I do know that when he was married before many years ago, they could have gone after assets owned by both him and his wife, as marital property, to recoup for CS he never paid on his first child.
I know about the can of worms, however, if this gets to a point of difficult child possibly going to my bro, it is best to open the can of worms. I'd told the GAL and judge a long time ago (in response to this direct question in court), I would prefer for difficult child to go to his father than to my bro if it ever got to a point where he could not live with me. His father does not want that, but time can be bought, I think, if necessary.
Really, DSS is already supposedly going after difficult child's father but evidently they aren't being too aggressive at this point.
I should add that according to online info, he has his own business so it shouldn't be hard to find him with a known business and home address.
