I don't know of one that exists. BK or any public record for that matter is the toughest to get removed from credit reports. They even have a VCIS (Voice command information services) that verifies BK's in all but a minute or two making a difficult situation even worse. Of course, if the BK is not yours, there are lots of good letters to get those off somewhere in the database section of this board.
I know on mine, both Experian and TU list the liabilities as $0. I was thinking of using the line 'I have never filed a 0 liability BK...' I heard someone did it and TU deleted.
