Everyone who files for bankruptcy is required to sign those documents attesting that they are truthful. They do so under penalty of perjury. The banakruptcy court and the US Trustee's office takes this very seriously. Sometimes, those filing for bankruptcy will accidentally omit an asset or a debt, and in those cases amendments can be made to made the filing accurate. However, an intention ommission will result in a discharge being denied or worse criminal prosecution.
Print out whatever evidence you have and take it to the U.S. Trustee. Fraud is taken seriously and they will investigate. If the case was filed fraudulently, then severe actions will be taken. Just be certain that your evidence is correct.
