Are you in the USA? I just did some googling on this as I was unaware of laws regarding the garnishment of wages. I have subordinates that have wages garnished for Child Support every paycheck. At least in my state, you can most certainly garnish wages/property for a judgement in your favor. It will probably take a bit more time, but I would stick it out to get my money back. If the contractor has nice Stihl saws, I would remand some $$$ to get one of them from him. Possibly even the truck as the contractor has probably depreciated the asset for tax reasons.
