Squatters rights in Montana come down to a single demanding rule: a person occupying land they don’t own can eventually claim legal title through adverse possession, but only after holding the property openly for five continuous years and paying every property tax bill assessed during that period. Short of that, an occupant without authorization is a trespasser, and Montana law lets law enforcement remove them from the property immediately, without a court order.1Montana State Legislature. Montana Code 70-24-113 – Removal of Unauthorized Person or Trespasser The tax requirement is what makes a successful claim rare in practice, and it is also what gives property owners their strongest defense.
What a Squatter Must Prove to Claim Ownership
Montana’s adverse possession framework sits across several statutes, and the courts have added common-law elements on top. The core rule bars any adverse possession claim unless the claimant shows the land was occupied and claimed continuously for five years and every tax bill was paid during that period.2Montana State Legislature. Montana Code 70-19-411 – Occupancy and Payment of Taxes Necessary to Prove Adverse Possession A separate statute sets the five-year threshold and presumes the legal titleholder has been in possession unless a challenger proves otherwise.3Montana State Legislature. Montana Code 70-19-404 – Presumption of Possession Within Prescribed Period, Adverse Possession as Exception
On top of the statutes, Montana courts require the possession to be:
- Open and notorious. The occupant uses the land in a way any reasonable neighbor or passerby would notice. Secret or hidden use doesn’t count.
- Hostile. The occupant holds the land without the owner’s consent. No lease, no handshake agreement, no permission of any kind.
- Exclusive. The occupant treats the land as theirs alone, not sharing control with the legal owner or the public.
- Continuous. The occupation runs unbroken for the full five years. Leaving the property for months at a time destroys the claim.
A casual trespasser is in a different category entirely. Entering or staying on property without permission is criminal trespass in Montana, punishable by up to $500 and six months in county jail, and a trespasser caught hunting or hiking on private land can lose hunting, fishing, and trapping privileges for up to 24 months.4Montana State Legislature. Montana Code 45-6-203 – Criminal Trespass to Property None of that time on the land builds any ownership right.
The Property Tax Rule That Defeats Most Claims
The tax payment obligation is what makes Montana’s law unusually hard on squatters. The statute requires payment of all taxes, state, county, or municipal, that were legally assessed against the land during the entire five-year period.2Montana State Legislature. Montana Code 70-19-411 – Occupancy and Payment of Taxes Necessary to Prove Adverse Possession Courts read this literally. A claimant who misses even one installment over those five years has likely destroyed the whole claim.
Montana property taxes come due in two installments each year, the first by November 30 and the second by May 31.5Montana Department of Revenue. Residential Property That means a claimant needs 10 consecutive on-time payments to cover the full period, verified through certified records from the county treasurer’s office.
This cuts the other way for owners. If the legal owner stays current on their own taxes, the squatter cannot satisfy the statutory mandate, and no amount of time on the land will produce a successful claim.
What Counts as Occupying the Land
Montana defines occupation differently depending on whether the claimant holds a written instrument. When a claimant has no deed, judgment, or other written document supporting the claim, the statute recognizes only two forms of occupation: enclosing the land with a substantial fence or barrier, or actively cultivating or improving it.6Montana State Legislature. Montana Code 70-19-410 – Claim of Title Not Founded on Instrument or Judgment, What Considered Occupation Camping on vacant land or parking a vehicle on it won’t satisfy the statute.
The rules are more generous when the claimant holds a written instrument, even a defective one. A person who possesses what appears to be a valid deed that turns out to be legally flawed has what courts call color of title. The court can then rely on the written description in the defective document to define the boundaries of the claim, rather than limiting it to the specific area the occupant physically used. Color of title expands the geographic reach of the claim to everything described in the document, as long as the other requirements are met.
When the Five-Year Clock Can Pause or Combine
Montana allows successive occupants to combine their time toward the five years, a concept called tacking. If one occupant holds land for three years and then transfers their interest to a second person who continues for two more, the combined time can meet the statute. The catch is that the occupants need a legal connection, such as a sale, written agreement, or inheritance. A squatter who simply abandons the property, followed by an unrelated person moving in, cannot tack.
A tolling provision pauses the five-year clock when the legal owner has a qualifying disability. If the true owner was a minor, was committed to an institution, or was imprisoned for a term less than life at the time the adverse possession began, the period of disability doesn’t count toward the five years. Once the disability ends or the owner dies, a new five-year window opens for the owner or their heirs to reclaim the property.7Montana State Legislature.

How to Remove a Squatter in Montana
Immediate Removal by Law Enforcement
The fastest route is calling the sheriff or local police. A person who cannot produce authorization to occupy a property is treated as an unauthorized person or trespasser and can be removed immediately by law enforcement.1Montana State Legislature. Montana Code 70-24-113 – Removal of Unauthorized Person or Trespasser No court order is required. If you arrive with your deed and the occupant has nothing showing they belong there, the statute puts the law on your side.
This works best when the squatter arrived recently and has no colorable claim to tenancy. It gets harder when the occupant claims a verbal lease, produces a dubious document, or has been there long enough that law enforcement is reluctant to act without a court ruling. In those situations, formal eviction is the path.
The Formal Court Process
When police won’t act on the spot, the owner files an action in court. You’ll want a recorded deed from the County Clerk and Recorder’s office as proof of ownership, along with any written notices previously delivered to the occupant. A physical description works for the initial paperwork if the squatter’s name is unknown.
The owner files a complaint with the court clerk and pays a filing fee, then arranges service of the summons by a sheriff’s deputy or private process server. Montana’s landlord-tenant statutes require the hearing to take place within 10 business days of the occupant’s appearance or answer date, with a ruling due within five days after the hearing. If the judge rules for the owner, the court issues a writ of possession and a writ of assistance immediately, and the sheriff has five business days to execute the writ and physically remove the occupant.8Montana State Legislature. Montana Code 70-24-427 – Landlords Remedies After Termination, Action for Possession
What Owners Should Not Do
Montana prohibits self-help eviction. Changing locks, shutting off utilities, or removing a person’s belongings without a court order can expose the owner to a wrongful eviction lawsuit, even when the occupant has no legal right to be there. An owner who goes this route risks paying damages of up to three times the monthly rent or actual damages. Law enforcement and the court process both move quickly under Montana’s statutory timelines, and they are the safer option in every case.
What a Successful Claimant Still Has to Do
Meeting the adverse possession requirements doesn’t automatically transfer ownership. Even after five years and 10 tax payments, the claimant still holds no legal title until a court says so. The mechanism is a quiet title action, which Montana allows any person claiming an interest in real property to bring against anyone with a competing claim.9Montana State Legislature. Montana Code 70-28-101 – Quiet Title Action Authorized
The claimant files in District Court and must prove every element: open, hostile, exclusive, and continuous occupation for five years, plus full tax payment throughout. The burden sits entirely on the claimant. If the court is satisfied, it issues a decree recognizing the claimant as the legal owner, which is then recorded with the County Clerk and Recorder’s office to update the public land records. Without that step, the claimant has no deed and cannot sell, mortgage, or otherwise deal with the property as an owner.
Keeping Squatters From Qualifying in the First Place
The most reliable defense is paying your property taxes. Because Montana requires the adverse possession claimant to pay every installment for five years, an owner who stays current makes it impossible for anyone else to meet that requirement. Most claims die here before they start.
Regular inspection of your property matters too, especially for rural land, vacant lots, or second homes. A squatter who builds a fence or starts farming a remote parcel could go unnoticed for years. Posting “No Trespassing” signs doesn’t legally prevent adverse possession, but the signs establish that you’re actively asserting ownership and give law enforcement a clearer basis to act under the criminal trespass statute.
If you discover someone on your property, act quickly. The five-year clock resets any time the owner reasserts control. A written notice demanding the person leave, delivered in person or by certified mail, creates a record that the occupation is not with your consent. If the person refuses to go, calling law enforcement to invoke the immediate removal statute or filing in court stops the clock before any viable claim can form.
