Yes, unless the support order says it is not to be modified. The court maintains continuing jurisdiction over spousal maintenance for the entire time it is awarded. When spousal maintenance is modifiable, either party has the right to ask that the court change the amount. In general, a maintenance award may be modified with a substantial change in circumstances following the original maintenance order. The parties may agree, however, that the maintenance order will not be modifiable. In that instance, non-modification of maintenance would be stated in the decree.
