The issue of cohabitation in Illinois divorce cases is an interesting one. Sometimes, a spouse that is receiving maintenance support engages in a relationship with a third party after the divorce. The payor spouse many times feels a bit cheated, in that a former spouse (payee) receives financial support while at the same time dating someone exclusively and sharing their home with him/her. In Mattson, a former husband felt burned that he was paying support to his ex-wife while she was engaging in a lengthy relationship with a Chicago sportscaster. The former husband hired private investigators to watch the former wife’s house. Former husband brought his case to Court.

Section 510(c) of the Dissolution Act provides that, “Unless otherwise agreed by the parties ***, the obligation to pay future maintenance is terminated upon the death of either party, or the remarriage of the party receiving maintenance, or if the party receiving maintenance cohabits with another person on a resident, continuing conjugal basis.” 750 ILCS 5/510(c) (West 2022).
