Eviction Process In Montana

Evicting a tenant in Montana means following unlawful detainer (forcible entry and detainer) action in Justice's Court or District Court exactly, start to finish. Skipping a step, whether it's the notice period, how the tenant is served, or the lockout procedure, can restart the clock or expose a management company to liability. This guide walks through each step with the statute or court rule behind it.

Everything below is sourced to Montana's own statutes and court self-help pages. Specific deadlines and dollar figures do change, so confirm the current text before you rely on a date in a live case.

Overview Of The Eviction Process

Montana's eviction action is "unlawful detainer" (or, for forcible entry, "forcible detainer"), governed by Title 70, chapter 27 of the Montana Code Annotated, alongside the termination and remedy provisions of the Residential Landlord and Tenant Act in Title 70, chapter 24, part 4.

  • Title 70, chapter 27 of the Montana Code Annotated governs "Forcible Entry and Detainer; Unlawful Detainer," with Part 1 covering definitions and preliminary procedure and Part 2 covering trial, judgment, and appeal. (Mont. Code Ann. Title 70, ch. 27)
  • Part 4 of the Residential Landlord and Tenant Act (Title 70, chapter 24) sets out landlord and tenant remedies, including termination for nonpayment and noncompliance. (Mont. Code Ann. Title 70, ch. 24, pt. 4)

Lawful Grounds For Eviction

Grounds include nonpayment of rent, breach of a lease covenant, holdover after a tenancy-at-will notice, and, under the Residential Act, curable and incurable noncompliance categories.

  • Unlawful detainer includes nonpayment of rent, following 3 days' written notice requiring payment, stating the amount due, served on the tenant and any subtenant in actual occupation. (Mont. Code Ann. § 70-27-108)
  • Unlawful detainer also includes breach of a lease covenant or condition (other than rent), following 3 days' written notice requiring performance; if the breach cannot be cured, no notice is required before proceeding. (Mont. Code Ann. § 70-27-108)
  • Under the Residential Landlord and Tenant Act, curable noncompliance generally requires 14 days' notice (3 days for unauthorized pets/occupants or verbal abuse), 5 days' notice for a repeat violation within 6 months, and incurable violations (unpaid rent, property destruction, safety hazards) allow 3 days' notice to vacate with no cure right. (Mont. Code Ann. § 70-24-422)

Notice Requirements

Nonpayment and lease-violation notices under the unlawful detainer statute are 3 days; noncompliance notices under the Residential Act range from 3 to 14 days depending on the violation.

  • For nonpayment, the landlord must serve 3 days' written notice requiring payment, stating the amount due; the notice may be served within one year after the rent becomes due. (Mont. Code Ann. § 70-27-108)
  • For breach of a lease condition or covenant, the landlord must serve 3 days' written notice requiring performance of the condition or covenant or surrender of the premises. (Mont. Code Ann. § 70-27-108)
  • Under the Residential Act, a curable noncompliance notice generally gives 14 days to remedy before termination, and if substantially the same violation recurs within 6 months, the landlord may terminate with 5 days' notice and no further cure period. (Mont. Code Ann. § 70-24-422)

Filing The Case

The action is commenced by a complaint and summons under the unlawful detainer chapter's procedural sections.

  • An unlawful detainer or forcible entry action is commenced by filing a complaint, followed by issuance of a summons. (Mont. Code Ann. §§ 70-27-113, 70-27-114)

Serving The Tenant

The summons is personally served if the defendant can be found in Montana; if not, service follows the alternate-service method for notices.

  • If the defendant cannot be found in the county, or is absent, personal service is required where the defendant can be located with reasonable effort; otherwise the summons is served in the same manner as notices under § 70-27-110. (Mont. Code Ann. § 70-27-114)
  • If a summons is not served, or not served timely, the plaintiff may obtain a new summons without penalty. (Mont. Code Ann. § 70-27-114)

The Tenant's Response

The defendant must appear and answer within 10 days of service or face a default judgment, and both the complaint and answer must be verified.

  • The defendant must appear and answer the complaint within 10 days of service of the summons, or a default judgment may be entered. (Mont. Code Ann. § 70-27-114)
  • Both the complaint and the answer in an unlawful detainer action must be verified. (Mont. Code Ann. § 70-27-116)

Hearing And Judgment

A justice's court action must be tried within 10 days, and a favorable judgment includes restitution of the premises plus, in rent-default or lease-breach cases, treble damages/rent.

  • Actions in justice's court under this chapter must be tried within 10 days. (Mont. Code Ann. § 70-27-202)
  • A judgment for the plaintiff includes restitution of the premises, forfeiture of the lease where based on breach of lease conditions or unpaid rent, any damages assessed, and a judgment equal to 3 times the assessed damages and rent found due. (Mont. Code Ann. § 70-27-205)

The Writ And Lockout

In rent-default cases where the lease continues, execution cannot issue until 5 days after judgment, during which the occupant may pay the full amount owed to retain possession; the statutory text reviewed does not itself name the executing officer or address property left behind.

  • For rent-default cases involving a continuing lease, execution on the judgment may not issue until 5 days after entry of judgment, and during that period the tenant may pay the full amount owed plus costs to satisfy the judgment and keep possession. (Mont. Code Ann. § 70-27-205)
  • In all other unlawful detainer cases, the judgment may be enforced immediately upon entry. (Mont. Code Ann. § 70-27-205)

Prohibited Practices

Montana bars self-help ouster of a tenant or purposeful diminution of essential services, with statutory damages of the greater of 3 months' rent or treble damages.

  • A landlord may not unlawfully remove or exclude a tenant from the premises, or purposefully diminish essential services such as heat, running water, hot water, electricity, or gas. (Mont. Code Ann. § 70-24-411)
  • A tenant subjected to such conduct may recover possession or terminate the rental agreement, and in either case may recover damages equal to the greater of 3 months' periodic rent or treble damages; if the tenant terminates, the landlord must also return security deposits and prepaid rent. (Mont. Code Ann. § 70-24-411)

Eviction is the last step in a relationship that's already gone wrong. See our guide to Montana property management laws and regulations for the licensing, disclosure, and trust-account rules that apply before it gets to this point.

Doing It By The Book

Self-help evictions, changing locks, removing doors, shutting off utilities, are illegal in every state and expose a management company to real liability regardless of how clear the nonpayment is. The court process exists because it's the only lawful way to remove a tenant, and skipping a step (a defective notice, bad service) is the single most common reason a case gets dismissed and restarted from day one.

This guide is a starting point for professional managers, not legal advice. For a specific case, a contested filing, or anything unusual, work with a Montana attorney, and confirm the current text of any rule cited above with Justice's Court or District Court or the Montana legislature.
