Yes – but only if the debtor can show “excusable neglect” they can amend their exemptions in a reopened proceeding.
However, in a recent 10th Circuit case, the court held that a Chapter 7 debtors failed to establish that their failure to disclose a personal injury claim, which they subsequently settled for $8,000, was the result of excusable neglect. As a result, the previously undisclosed personal injury claim was not exempted from the bankruptcy estate because the Chapter 7 debtors failed to establish that their failure to disclose a personal injury claim, was the result of excusable neglect.
