Roommate money dispute in Montana small claims

When a roommate leaves without paying their share of rent, utilities, or other agreed expenses — or when money was lent and not repaid — small claims court is an accessible option to recover. Your case turns on showing what was agreed, what was paid by each person, and what remains unpaid. A written roommate agreement or lease addendum is the strongest evidence, but texts, emails, and payment records can also establish the arrangement.
