The notices and their periods
- 3-Day Notice to Pay or Quit — for nonpayment (Mont. Code § 70-24-422(2)) — three days to pay or move out.
- 3-Day Notice (specific violations) — three days to cure an unauthorized pet, unauthorized occupants, or verbal abuse of the landlord (§ 70-24-422(1)(b),(c),(f)).
- 14-Day Notice (other violations) — fourteen days to cure any other lease violation (§ 70-24-422(1)(d)). Serious damage or destruction can be a 3-day notice with no cure (§ 70-24-422(3)–(4)).
Ending a tenancy and serving notice
To end a month-to-month tenancy without cause, give 30 days' written notice (Mont. Code § 70-24-441); a week-to-week tenancy requires 7 days.
After the notice period, the landlord files in court (Mont. Code § 70-27-101). Montana follows the Uniform Residential Landlord and Tenant Act and bars self-help eviction.
Match the violation to the right clock
Montana sorts lease-violation notices by type: unauthorized pets or occupants and verbal abuse of the landlord get a 3-day cure; most other violations get 14 days; and serious damage or destruction can be a 3-day notice with no cure at all. Picking the wrong period is a common, case-ending mistake.

WriteMyNotice.com is a self-help document preparation service, not a law firm, and this page is general information, not legal advice. Eviction rules are strict and vary by state, county, and city — many cities add rent-control or just-cause requirements on top of state law, and an improper or mistimed notice can get an eviction case delayed or dismissed. Verify the current requirements for your property's location and, for contested or high-stakes evictions, consult a landlord-tenant attorney. Statute references verified June 2026.
