Breaking a Lease in Montana: The Re-Renting Rule Caps Your Bill

By Steve Levine · Updated November 3, 2026

Short answer: Breaking a lease in Montana usually costs you rent only until the landlord re-rents the unit, because Mont. Code Ann. § 70-24-426(3) requires a good-faith effort to find a new tenant at a fair rent. Montana has no state statute letting domestic violence survivors end a lease early, so the realistic legal exits are federal military protection, serious habitability failures under § 70-24-406, an illegal lockout or utility shutoff, and fire or casualty damage.

The Montana Residential Landlord and Tenant Act is lean. It doesn’t regulate early termination fees, it gives no special exit to older tenants, and it requires the landlord’s written consent before you hand the unit to someone else. That makes the re-renting rule and your paperwork the two things that decide what you’ll actually pay.

Legal exits from a Montana lease

Military service (federal law)

The Servicemembers Civil Relief Act at 50 U.S.C. § 3955 lets you end a residential lease if you entered active service after signing it, or if you signed while serving and then got permanent change-of-station orders or deployment orders for 90 days or more. You deliver written notice plus a copy of the orders. On a monthly lease, termination takes effect 30 days after the next rent due date following delivery, and rent you paid in advance for later periods must be refunded within 30 days. Montana’s landlord-tenant chapter adds no separate military section.

Domestic violence: no Montana termination statute

We reviewed the section lists for all four parts of Title 70, chapter 24, and none creates an early-termination right for survivors of domestic violence, sexual assault or stalking. The closest provision, § 70-24-111, only says a “notice of no contact” between a landlord and tenant is valid when a court no-contact order or order of protection backs it. If you need to leave for safety, ask the landlord for a written mutual release, offer a replacement tenant, and lean on the re-renting duty described below.

The unit is unsafe or unlivable

When a landlord’s failure to meet the § 70-24-303 maintenance duties affects health and safety, § 70-24-406(1)(a) lets you serve written notice describing the problem and naming a termination date at least 30 days after the landlord receives it. If the landlord fixes it within 14 days, the lease survives. For an emergency, the window drops to 3 working days. If substantially the same problem comes back within 6 months, you can terminate on 14 days’ written notice. You can’t use this route for damage you or your guests caused.

Lockouts, utility shutoffs and illegal entry

A landlord who removes you, locks you out, or purposefully cuts heat, running water, hot water, electricity or gas hands you an exit. Under § 70-24-411 you may terminate and recover up to three months’ periodic rent or treble damages, whichever is greater, and the landlord must return your deposit and prepaid rent. Repeated unlawful entry or unreasonable demands to enter is a lesser ground: § 70-24-410 lets you seek an injunction or terminate, plus actual damages.

Fire or casualty damage

If a fire or other casualty substantially impairs your use of the unit, § 70-24-409 lets you move out and send written notice within 14 days. The lease ends on the day you vacate, rent is accounted for as of the date of the damage, and the landlord must return your recoverable deposit and any prepaid rent.

Age or disability

Montana’s chapter 24 has no early-release provision for older tenants or tenants who move into assisted living or a nursing facility. If health or a move into care is the reason you need to leave, a written mutual release negotiated with the landlord, or a replacement tenant the landlord approves, is the practical route.

How the re-renting duty limits what you owe

If you leave without a legal exit, the lease doesn’t vanish, but your bill has a ceiling. Section 70-24-426(3) says that when a tenant abandons the unit, the landlord must make a good-faith effort to rent it at a fair rental. If the landlord re-rents for a term starting before your lease would have expired, your agreement ends on the date the new tenancy begins.

The statute also punishes a landlord who sits on an empty unit. If the landlord makes no good-faith effort, or treats your departure as a surrender, your agreement ends on the date the landlord had notice of the abandonment. That’s why a dated written notice that you’ve left, with your keys, matters so much in Montana.

Early termination fees and lease clauses

Montana’s prohibited-provisions section, § 70-24-202, bars clauses that waive your statutory rights, confess judgment, or excuse the landlord’s own negligence. It says nothing about buyout fees or liquidated damages, so a reasonable fee you agreed to is not automatically void. A court can still refuse to enforce an unconscionable term under § 70-24-404.

Watch for one Montana detail: § 70-25-201 lets a landlord deduct “penalties under the lease provisions” from the deposit, along with unpaid rent and late charges. A lease-break fee written into your lease can come straight out of your deposit.

Subletting or handing over the unit

Under § 70-24-305, a tenant who leaves during the lease may not let someone else take possession or sublet without the landlord’s or agent’s written consent. Montana doesn’t require the landlord to be reasonable about it, so get the yes in writing before your replacement moves in. A signed sublease or assignment, or a new lease with your replacement, is the cleanest way out.

Your deposit when you leave early in Montana

Under § 70-25-202, the landlord has 30 days after the tenancy ends or a surrender is accepted to send a written list of rent due and damage and cleaning charges. If there’s nothing to deduct and you show no unpaid utilities, the full deposit is due within 10 days. Rent owed for the months before re-renting is a lawful deduction.

Cleaning is where early leavers lose money. Section 70-25-201 normally requires written notice listing the cleaning needed and gives you 24 hours to do it, but that protection disappears if you leave without saying you intend to vacate. Tell the landlord in writing before you go. For the full deposit rules, see our Montana security deposit law guide.

Worked example: breaking a Bozeman lease

Dana rents a Bozeman apartment for $1,500 a month on a lease running through June 30, 2027, with a $1,500 deposit and no buyout clause. A job in Spokane means she must leave. On January 10, 2027, she hands the landlord a written notice that she’ll vacate on January 31, pays January rent, returns her keys on the 31st, and leaves a forwarding address.

The landlord lists the unit in early February and signs a new tenant whose lease starts March 16. Under § 70-24-426(3), Dana’s lease ends March 15. She owes February rent of $1,500 plus March 1 to 15, about $740 at a daily rate of $1,500 times 12 divided by 365, for roughly $2,240 total. The landlord sends an itemized list within 30 days, keeps the $1,500 deposit against it, and bills Dana for about $740.

If the landlord had never advertised the unit, Dana could argue her lease ended on January 31, when the landlord had notice she’d left. Try your own numbers in the break-lease cost calculator.

Giving notice and documenting your move-out

Put it in writing. Montana’s notice rule, § 70-24-108, recognizes hand delivery, certificate of mailing and certified mail, and treats mailed notice as served 3 days after mailing.
Use the right deadline. A month-to-month tenant needs 30 days’ written notice under § 70-24-441(2). A habitability exit needs the 30-day termination date and 14-day cure window in § 70-24-406.
Ask for a cleaning list. Your written notice that you’re leaving keeps the 24-hour cleaning notice under § 70-25-201 alive.
Photograph every room on move-out day and keep dated copies of your keys receipt and forwarding address.
Track re-renting. Screenshot rental ads for your unit; they show whether the landlord made a good-faith effort.

Frequently Asked Questions

Can I break my lease in Montana because of domestic violence?

Montana has no statute that ends a lease for survivors, so you’d negotiate a release or rely on the landlord’s re-renting duty under § 70-24-426(3). A court no-contact order or order of protection makes a related “notice of no contact” valid under § 70-24-111. A local legal aid office can help with the paperwork.

Does my Montana landlord have to accept my replacement tenant?

No statute forces the landlord to accept a subtenant, and § 70-24-305 requires written consent before anyone else takes possession. Offering a qualified replacement still helps you, because refusing one weakens a landlord’s claim of a good-faith effort to re-rent.

Can my landlord take a lease-break fee from my deposit?

If the fee is in your lease, likely yes. Section 70-25-201 allows deductions for penalties under lease provisions, unpaid rent and late charges, and the itemized list must arrive within 30 days under § 70-25-202.

What if the heat goes out in January and the landlord won’t fix it?

Loss of heat in a Montana winter is the kind of emergency § 70-24-406 treats on a short clock: if it isn’t fixed within 3 working days of your written notice, you may terminate. If the landlord cut the heat on purpose, § 70-24-411 adds damages of the greater of 3 months’ rent or treble damages.

Where do I file if my landlord won’t return my deposit?

Montana justice courts hear small claims up to $7,000 under § 25-35-502. Bring your move-out photos, your written notice and the landlord’s itemized list.

Your next step: write your notice today, date it, deliver it by a method § 70-24-108 recognizes, and keep a copy.
