If your spouse remarries a wealthy person, you’re not necessarily entitled to more spousal maintenance. Spousal maintenance is a division of income between you and your ex-spouse, but it’s based upon one person’s need and another person’s ability to pay. If a person is living by themselves, they have a reduced ability to pay because they have to meet their own needs as well. But when that person remarries, that additional supplemental income reduces the payor’s need for that income and increases their ability to pay spousal maintenance. So while you’re not entitled to income from their new spouse, it may free up additional income from your ex to pay spousal maintenance to you.
