Modification Allowed
Reduction of income was the type of substantial change in circumstances contemplated by subsection (a) and thus it was error for the trial court to decline to modify the maintenance award.
Because the terms of the judgment did not incorporate the terms of a settlement agreement pursuant to 75 ILCS 5/502(f), the court had power to modify the maintenance award.
Modification of maintenance was appropriate where the husband presented evidence that he had chosen to cease working upon the advice of his physician and following heart pains significant enough to cause his hospitalization and his business required work seven days a week.
Although the ancillary order limited termination of maintenance to the conditions therefore in this section, it made no express reference to any conditions precluding modification as to the amount of maintenance and, therefore, did not preclude modification.
Modification of maintenance provisions of a 1975 settlement agreement was allowed using the standards of this section, even though enacted after 1975.
Where an option concerning disposition of a home required respondent to pay monthly rent to petitioner, the award was a form a maintenance which the court could not allow where petitioner was cohabiting with another.
