Montana Month-to-Month Lease Agreement

Last Updated: December 18, 2023 by Roberto Valenzuela

A Montana month-to-month rental agreement is a contract (not necessarily in writing) which allows a tenant to rent property from a landlord, for one month at a time, in exchange for a fee (“rent”). The rental renews monthly, until either party gives proper notice to end it.

Basics of a Montana Month-to-Month Rental Agreement

In Montana, a landlord and tenant create a month-to-month lease by agreeing to rent a property according to acceptable terms. Written rental agreements are clearer and legally stronger, but oral leases are legal in a month-to-month context.

Parties under a month-to-month lease enjoy full rights under Montana landlord-tenant law. The tenant must use the property in a responsible way and pay rent on time. The landlord must keep essential features of the property in habitable condition, and protect the tenant’s quiet enjoyment of the lease.

The main difference between a month-to-month lease and a fixed-term lease is that month-to-month leases can be terminated (with proper notice) by either party for any reason without penalty. Landlords also can usually modify terms from one month to the next, again with proper notice.
