Unless otherwise agreed in writing or expressly provided in the divorce decree, the obligation to pay future maintenance is terminated upon the death of either party or the remarriage of the party receiving maintenance.
Child support, on the other hand, may still be owed after the paying parent dies.
Unless otherwise agreed in writing or expressly provided in the court orders, provisions for the support of a child are not terminated by the death of a parent obligated to support the child. When a parent obligated to pay support dies, the amount of support may be modified, revoked, or commuted to a lump-sum payment, to the extent just and appropriate in the circumstances.
