When Joseph Richardson (plaintiff) and Ida Richardson (defendant) divorced, they entered into a separation agreement whereby Mr. Richardson promised to pay Mrs. Richardson maintenance of $2,425 per month until she remarried or either party died. The agreement was expressly characterized as being nonmodifiable regardless of the circumstances. The trial court incorporated the agreement into the divorce decree after determining that it was not unconscionable. Several years after the divorce, Mr. Richardson petitioned to terminate his maintenance obligation on the grounds that Mrs. Richardson had attempted to hire people to burglarize Mr. Richardson’s home and to kill him. The trial court dismissed Mr. Richardson’s petition, and he appealed.
