Yes. If either ex-spouse can demonstrate a substantial change in circumstances, they can file a motion with the court to modify alimony upwards or downwards or to terminate alimony entirely. A paying spouse may seek to reduce their alimony obligation if they experience a substantial decrease in their income or earning capacity or to terminate alimony upon their ex-spouse’s remarriage or cohabitation with a romantic or intimate partner. A recipient spouse might even seek an increase in alimony if they experience a substantial, unexpected increase in their expenses, such as from medical expenses.
