A claim that the court has approved for payment under a plan of reorganization. Creditors are entitled to vote on a plan only if their claims are impaired and allowed. Claims are deemed allowed if they are scheduled (§ 501, Bankruptcy Code) or filed (§ 502, Bankruptcy Code), unless a party in interest (such as the debtor or the creditors' committee) objects. A claim or interest that is listed on the debtor's schedules as undisputed, noncontingent, and liquidated is also deemed allowed unless objected to.
