Many self-employed debtors file bankruptcy because they have personally guaranteed debt of their failing business. Some of these debtors want to discharge their guarantees of business bank loans or credit cards used for the business, and they want to try to resurrect the business after they have been cleared of personal liability. In such cases, the debtor has to value his interest in the business. The debtor must value his stock, membership interest, or other form of ownership in his business.
