The court may grant a "hardship discharge" to a chapter 12 debtor even though the debtor has failed to complete plan payments. 11 U.S.C. § 1228(b). Generally, a hardship discharge is available only to a debtor whose failure to complete plan payments is due to circumstances beyond the debtor's control and through no fault of the debtor. Creditors must have received at least as much as they would have received in a chapter 7 liquidation case, and the debtor must be unable to modify the plan. For example, injury or illness that precludes employment sufficient to fund even a modified plan may serve as the basis for a hardship discharge. The hardship discharge does not apply to any debts that are nondischargeable in a chapter 7 case. 11 U.S.C. § 523.
