I realize that money is tight for you, but you really need to sit down with a lawyer to review the history of this matter, and get some advice.
From here, it looks like the key is the order and/or judgment saying that you are owed the $70,000. It may be an enforceable judgment. Without seeing the paperwork and knowing whom the order/judgment is against, I don't know that I can say anything more. It may be that an hour or so of a lawyer's time is all you need to advise you on what you need to do, and that you can do the legwork after that.
Good luck to you.
