Eviction Laws in Montana
Non-payment of rent eviction in Montana
When a tenant falls behind on rent in Montana, the landlord must first serve a 3-day pay-or-quit notice. This gives the tenant 3 days to either pay the full amount owed or vacate. If the tenant does neither, the landlord can file an eviction lawsuit — called an unlawful detainer or summary possession action — in Montana court.
A court order is required before any lockout. The landlord cannot change the locks, shut off utilities, or remove the tenant's belongings before winning a judgment.
Lease violation eviction in Montana

If corrected within that window, the tenancy continues. If not cured, the landlord may proceed with filing.
Terminating month-to-month tenancy in Montana

What counts as an illegal eviction in Montana?
In Montana, a landlord who attempts to evict a tenant without following the legal process commits an illegal (self-help) eviction. This includes:
- Changing the locks without a court order
- Removing doors, windows, or the tenant's belongings
- Shutting off utilities (electricity, water, heat)
- Harassment designed to pressure the tenant to leave
Self-help evictions are prohibited in all 50 states and DC. Tenants who experience an illegal lockout can typically seek emergency relief from a court and may be entitled to damages.
