Can you file chapter 7 on judgment received from fruad?

First, you never file BK on an item...BK is on everything you owe and everything you won...you do not pick and chose what is involved...with a few exceptions, all of your assets can be (and are) taken and used to pay off all of your debts. With debts given certain levels of priority by law (not choice)...

Received....as in your getting it? You don't file bankruptcy over getting money.
If you meant it's something you've got to pay...BK generally won't get you out of a legal judgement.
