A bankrupt photographer sued for loan repayment after discharge, but the court ruled he had no right to pursue the claim. Any debts or assets not listed in the bankruptcy schedules belong to the bankruptcy estate and must be handled by the trustee, not the debtor. This means once you file bankruptcy, unlisted claims pass to the trustee—you can't recover them yourself later, even if you win in court.
If you file bankruptcy, list ALL debts and claims upfront. Unlisted items go to the trustee permanently and you lose the right to pursue them.
