(1) If the debtor is unable, once discharge of residual debt has been granted, to pay the deferred amount from his or her income and assets, the court may extend deferment and set the monthly instalments to be paid. Section 115 (1) to (3) and section 120 (2) of the Code of Civil Procedure apply accordingly.
(2) The court may alter the ruling regarding the deferment and the monthly instalments at any time insofar as any personal or economic circumstances relevant to the deferment have undergone major changes. The debtor is obliged to report to the court a major change in these circumstances without delay. Section 120a (1) sentences 2 and 3 of the Code of Civil Procedure applies accordingly. A change placing the debtor at a disadvantage is ruled out if four years have passed since termination of the proceedings.
