The Montana 5-day repeat violation is used to inform a tenant that their tenancy is terminating due to a repeat lease violation and that an eviction lawsuit may be filed against them if they fail to vacate in five (5) days. Landlords may only use this notice if the lease violation is the same or substantially similar to a violation of which notice was delivered within the previous six (6) months. Following receipt of the notice by the tenant, they will have five (5) days to vacate the rental unit. Failure on the tenant’s part to vacate within the prescribed notice period shall authorize the landlord to file for eviction.
