My question involves a marriage in the state of: Idaho

I was awarded a substantial financial settlement in my divorce judgement in 1997. My ex was unable to pay, and tried to go bankrupt. He was unable to make minimum payments and thus lost protection of bankruptcy. He has never paid me a penny. My questions:
Am I able to put a lien on any property he might have in another county than the one we lived in?
Am I able to pursue satisfaction of the judgement?
What would be my first step (after finding a good lawyer)?
thank you!
