How to Evict a Tenant in Montana: The Step-by-Step Legal Process (2026)

First: Take a Breath

Nobody wants to evict someone. It's stressful, it's expensive, and it feels terrible — even when the tenant has genuinely wronged you. But if you're here, you probably don't have a choice anymore.

Here's the good news: Montana's eviction process is straightforward and relatively fast (3–8 weeks). The bad news: if you skip steps or try shortcuts, you'll end up back at square one — or worse, facing legal liability yourself.

This guide walks you through the entire process. Follow it exactly.

The 5 Phases of a Montana Eviction

Every Montana eviction follows the same five steps. You cannot skip any phase. You cannot start at phase 3. Each step creates the legal foundation for the next one.

Phase 1: The Written Notice

Before you can file anything in court, you must give the tenant a written notice and wait for the notice period to expire.

The type of notice depends on why you're evicting:

Reason for Eviction	Notice Period	Can Tenant Fix It?
Nonpayment of rent	3 days	Yes — pay in full to stay
Lease violation (fixable)	14 days	Yes — cure the violation
Lease violation (repeated)	5 days	No — "incurable" after 2nd offense
Unauthorized persons/pets	3 days	Varies
Illegal activity on premises	3 days	No
End of month-to-month (no cause)	30 days	N/A — tenancy simply ends
End of fixed-term lease	No notice needed	N/A — lease expires by its terms

What the Notice Must Include

• Your name (the landlord)
• The tenant's name
• The property address
• The specific reason for eviction
• The deadline to fix it (if curable) or vacate
• The date the notice was given
• How it was delivered

How to Deliver the Notice

Montana law accepts these delivery methods:

• Hand-delivered to the tenant personally
• Left with someone at the tenant's residence (if the tenant isn't home)
• Posted on the door AND mailed (if no one answers)
• Email or text (technically acceptable, but hard to prove in court — always follow up with a paper copy)

Keep a copy for yourself. Write down the date, time, and method of delivery. You'll need this in court.

Phase 2: Filing the Complaint

If the notice period expires and the tenant hasn't fixed the problem or moved out, you can file an eviction lawsuit. In Montana, this is called a Forcible Entry and Detainer action.

Where to File

File at the county courthouse in the county where the property is located. You'll file in Justice Court (Montana's equivalent of small claims court) for straightforward evictions.

What You'll Need

• A completed eviction complaint form (available free from courts.mt.gov)
• A copy of the notice you served
• A copy of the lease (if applicable)
• The filing fee (typically $30–$75 depending on the county)
• Any documentation of the violation (photos, rent ledger, etc.)

What the Complaint Says

Your complaint tells the court:

• Who you are and who the tenant is
• Where the property is
• What notice you gave and when
• Why the tenant should be removed
• That you're asking the court to order the tenant to leave

Phase 3: Serving the Tenant

After you file, the court issues a summons — an official notice telling the tenant they're being sued and must respond.

The summons and complaint must be served on the tenant. You cannot do this yourself. Service must be done by:

• A county sheriff or deputy
• A professional process server
• Any person over 18 who is not a party to the case

The server will file a proof of service with the court confirming when and how the papers were delivered.

The Tenant's Response Window

Once served, the tenant has 5 business days to file a written "Answer" with the court. If they don't respond, you can request a default judgment — meaning you win automatically.

If they do respond, the case goes to a hearing or trial.

Phase 4: The Hearing

The court schedules a hearing, usually within 10 days of filing. At the hearing:

• You present your case (notice, lease, evidence of violation)
• The tenant presents their defense (if any)
• The judge decides

Common Tenant Defenses

Be prepared for these arguments:

• "I never received the notice" (this is why your delivery documentation matters)
• "The landlord didn't maintain the property" (retaliation/habitability defense)
• "I already fixed the violation" (only works if fixed within the cure period)
• "The eviction is discriminatory" (fair housing defense)

If You Win

The judge issues a judgment for possession — a court order saying the tenant must leave. The judge will set a deadline (usually 5 days).

If the Tenant Doesn't Leave After Judgment

Move to Phase 5.

Phase 5: Writ of Possession

If the tenant ignores the court order, you can request a Writ of Possession. This authorizes the county sheriff to physically remove the tenant and their belongings.

The sheriff will:

1. Post the writ on the property (giving a final deadline, usually 24-48 hours)
2. Return with deputies to perform the lockout
3. Supervise the removal of the tenant and their property

You do not do this yourself. The sheriff handles it. You may need to arrange for a locksmith to change the locks and movers/storage for the tenant's belongings (laws vary by county on property storage requirements).

Total Timeline

Phase	Typical Duration
Notice period	3–30 days (depends on type)
Court filing + summons	3–7 days
Tenant response period	5 business days
Hearing scheduled	5–10 days
Judgment compliance	5 days
Writ of possession (if needed)	3–7 days
Total	3–8 weeks

A nonpayment eviction with no tenant response can resolve in as little as 3 weeks. A contested eviction with a hearing can take 6–8 weeks.

Critical Mistakes to Avoid

Never Do "Self-Help" Evictions

In Montana, the following are criminal offenses — not just civil wrongs, actual crimes:

• Changing the locks while the tenant is out
• Shutting off utilities (water, heat, electricity)
• Removing the tenant's belongings
• Blocking entry to the unit
• Threatening or intimidating the tenant into leaving

Even if your tenant hasn't paid rent in three months and is destroying the property, you cannot take matters into your own hands. You must go through the court process.

If you perform a self-help eviction, the tenant can:

• Call the police (you may be arrested)
• Sue you for damages
• Get a court order forcing you to let them back in
• Recover attorney fees and potentially punitive damages

It's not worth it. Three extra weeks of patience costs far less than a lawsuit.

Don't Accept Partial Rent During the Notice Period

If you give a 3-day notice for nonpayment and then accept a partial rent payment, you may have just waived your right to proceed with that eviction. Once you accept money, some judges will rule that you've restarted the landlord-tenant relationship.

If you decide to accept partial payment and continue the tenancy, get a written agreement. Otherwise, don't take any money after serving notice.

Keep Records of Everything

• Every notice (with delivery date and method)
• Every text, email, or letter to/from the tenant
• Photos of property damage (timestamped)
• Rent payment records
• Maintenance requests and your responses
• The lease itself

Courts want documentation. "He said, she said" loses cases.

What It Costs

Expense	Typical Amount
Court filing fee	$30–$75
Process server	$30–$75
Sheriff writ service	$50–$100
Attorney (if you hire one)	$500–$2,000+
Lost rent during process	1–2 months

You can handle a straightforward eviction yourself using the free court forms. For contested cases, messy situations, or if you're unsure about procedures, an attorney is worth the investment.

One Last Thing

If you can resolve the situation without an eviction — a conversation, a payment plan, or helping the tenant find a new place — it's almost always cheaper and faster than going through the courts. Eviction should be the last resort, not the first response.

But when it is necessary, follow the process exactly. No shortcuts. The law protects both you and your tenant, and following it correctly protects your investment.
