How the hell can they do that?
In 1996 we bought a business together, and among all of the papers I signed, I signed a personal guarantee with this vendor.
When we divorced, he got the business and I got a court order stating I was to be held "harmless" of any debt incurred after such and such date, in 1999.
Well, that court order doesn't void the personal guarantee, apparently, so several years later, he ditches out on the business and just doesn't pay people, they cant' find him but they find me, so they come after me, and drop the suit against him.
I couldn't even find him. Rat bastard.
