Until you put his feet to the fire and he begs you to reconsider.
How did you manage to successfully sue somebody and get a judgment for $100,000? I imagine you had a lawyer. Where is that lawyer now and why aren't you using him to go after your enemy, even if he takes a percentage?
You'll never see a nickel of that $100,000 if all you are going to do is worry about all the ways you can't collect. Someone who can spend $60,000 in 3 months isn't invulnerable to what your lawyer can do to him that you apparently cannot.
