Can a co-owner commit trespass by leasing property without the other owner's consent? Mueller v. Allen Explained
Summary

David rented the property to the McCandless family without Elizabeth’s consent, and the family eventually purchased the home. Elizabeth sued David and his mother Susan Allen for trespass and tortious interference with economic relations.

Analysis
The Utah Court of Appeals addressed an important question about co-ownership rights and trespass in Mueller v. Allen, clarifying when one co-owner can be held liable for trespassing against another co-owner’s property rights.
Background and Facts
Elizabeth Mueller and David Allen purchased a home as joint tenants during their marriage. After their divorce, the court ordered them to sell the property “as soon as reasonably practicable.” When initial buyers (the McCandless family) could not secure financing, David signed a rental agreement with them without Elizabeth’s consent. Elizabeth never signed the agreement and later sued David and his mother Susan Allen for trespass and tortious interference with economic relations. The McCandlesses eventually obtained financing and purchased the home.
Key Legal Issues
The court addressed whether the divorce court had exclusive jurisdiction over property disputes, whether res judicata barred the claims, and most significantly, whether David’s leasing of the jointly-owned property constituted trespass against Elizabeth’s ownership rights.
Court’s Analysis and Holding
The court held that joint tenants each have the right to “free and unobstructed possession and enjoyment” of jointly held property, including the right to lease the property. Trespass between co-owners requires an actual ouster – either “an act of exclusion or use of such a nature that it necessarily prevents another cotenant from exercising his rights in the property.” The court found no evidence that Elizabeth wanted to reoccupy the property or that David’s actions excluded her from doing so. Importantly, David was acting pursuant to the divorce decree’s directive to sell the property, and the McCandlesses were the only interested buyers.
Practice Implications
This decision clarifies that mere disagreement with a co-owner’s leasing decisions does not constitute trespass absent evidence of actual exclusion or ouster. For family law practitioners, the case demonstrates that divorce courts do not have exclusive jurisdiction over all post-divorce property disputes, particularly when third parties are involved. The decision also reinforces that co-owners have broad rights to lease their interests, especially when acting to fulfill court orders requiring sale of the property.
