Before confirmation of a plan, several activities may take place in a chapter 11 case. Continued operation of the debtor's business may lead to the filing of a number of contested motions. The most common are those seeking relief from the automatic stay, the use of cash collateral, or to obtain credit. There may also be litigation over executory (i.e., unfulfilled) contracts and unexpired leases and the assumption or rejection of those executory contracts and unexpired leases by the debtor in possession. 11 U.S.C. § 365. Delays in formulating, filing, and obtaining confirmation of a plan often prompt creditors to file motions for relief from stay, to convert the case to chapter 7, or to dismiss the case altogether.
