The Missouri roommate agreement establishes rules and procedures that roommates must abide by while living under the same roof. Although not required by law, a roommate agreement helps create a comfortable and safe living environment that accommodates the expectations of each tenant. The agreement establishes boundaries concerning firearms, overnight guests, noise restrictions, and cleanliness. It also determines how the rent, utilities, and other bills will be split. Setting forth these terms in a binding agreement prevents disagreements over conditions that would otherwise be left undefined in a standard lease.
