Montana Residential Lease Agreement Requirements

While Montana is relatively permissive regarding rent amounts and term lengths, the state forcefully regulates precisely what can and cannot be written into a residential lease agreement.

Under the Montana Residential Landlord and Tenant Act of 1977, writing a "prohibited provision" into your lease doesn't just render that specific sentence unenforceable—if the landlord deliberately attempts to enforce it anyway, they can face severe financial penalties.

The Bedrock Rule: Good Faith

Montana law imposes an overarching "Obligation of Good Faith" (MCA § 70-24-111). Every duty established by the Landlord and Tenant Act, and every act performed under a lease agreement, must be executed in good faith. If a landlord uses a technicality in a lease clause to maliciously evict a tenant, a Montana court can strike the action down.

Essential Lease Elements

While standard elements like rent amounts and lease dates are obvious, a compliant Montana lease must include:

1. Disclosure of Identity: The lease must clearly identify the name and address of the person authorized to manage the premises, and the owner (or the owner's agent) authorized to receive legal notices and demands.
2. Move-in Condition Statement Attachment: If a security deposit is collected, the mandatory "Statement of Condition of the Premises" must be provided before the tenant moves in.
3. The Mold Disclosure: Every rental agreement must include the statutory Mold Disclosure Statement. (See our Required Disclosures guide).
4. Late Fee Limitations: The lease must explicitly define the late fee structure, and it cannot violate the statutory cap of the greater of 10% of monthly rent or $25.

Prohibited Lease Provisions (What NOT to Include)

Under MCA § 70-24-202, you cannot force a tenant to sign away their statutory rights. A rental agreement may not provide that the tenant:

• 1. Waives Legal Remedies: The tenant cannot agree to waive any rights or remedies available under the Montana Residential Landlord and Tenant Act.
• 2. Agrees to Pay the Landlord's Attorney Fees: The lease cannot mandate that the tenant will automatically pay the landlord's attorney fees if a dispute arises. (In Montana, the prevailing party in a landlord-tenant lawsuit is usually awarded attorney fees by the judge, but you cannot pre-determine this in the lease).
• 3. Exculpatory Clauses: The lease cannot contain a clause where the tenant agrees to "indemnify and hold harmless" the landlord from liability arising from the landlord's own negligence, or from the landlord's failure to maintain a safe, habitable building.
• 4. Confession of Judgment: The lease cannot force the tenant to authorize a third party to confess judgment on a claim arising from the lease agreement.

The Penalty for Prohibited Clauses

If a landlord includes a prohibited provision in the lease, that specific provision is "unenforceable."

However, if a landlord knowingly uses a lease containing these illegal provisions and tries to enforce them against the tenant in court, the tenant can countersue. The tenant may recover actual damages and an amount up to three months' periodic rent.

See our Eviction Process guide.

Subletting and Assignment

Montana law does not grant residential tenants an automatic, statutory right to sublet their apartments.

Whether a tenant can sublet their unit to a third party is determined entirely by the language in the lease agreement. Most Montana landlords utilize a clause that strictly prohibits subletting or assigning the lease without the landlord's express, prior written consent. If a tenant sublets in violation of this clause, they are breaching the lease and are subject to a swift 14-Day Notice to Cure or Quit.
