Forget it... If you don't have a secured interest in anything, you won't get a penny...
Good friend of mine declared bankruptcy last year, to the tune of 122,000$ of debt.
He kept almost everything too!! Also, he just had a new roof put on his house, and owed the contractor 6 or 7k for the job. He put that on the bankruptcy, and the contract lost out. How can you have a secured interest in a roof? Let alone a lawn. =p
