My spouse quit a higher-paying job to take a lesser-paying job. I believe my spouse did it to get out of paying spousal maintenance. Do I have any arguments I can make?

Yes. You can argue that your spouse should be attributed their former income for purposes of determining spousal maintenance. To persuade the court, you will need to show your spouse’s decision to change job was unreasonable and that they are voluntarily and unreasonably underemployed.
