The Montana thirty (30) day notice to quit is a document which notifies a tenant that their landlord will be ending a month-to-month lease or rental agreement. The landlord can deliver this document either by mail or in-person. If the tenant receives the notice by mail, they will be given an additional (3) days notice from the date that it was posted. Once the notice period has passed, the tenant must have vacated the premises or they will risk being evicted by court order. When terminating a month-to-month arrangement, the landlord does not need to provide their tenant with a reason for doing so.
