Here’s a scenario that’s more common than you’d think in the Flathead Valley, especially with vacant land, seasonal cabins, or a property you inherited and haven’t visited in a while: you drive out to check on a place and discover someone’s been living there. Maybe it’s been weeks. Maybe it’s been years. Your first question is probably some version of “can they actually take my property just by staying here?”
The short answer for Montana is: it’s a lot harder than people assume, and a lot of what circulates online about “30-day squatters rights” is simply wrong. But “hard” isn’t the same as “impossible,” and there’s a right way and a wrong way to handle it once you find someone on your land.
Squatter, Trespasser, or Holdover Tenant — The Distinction Matters
Before anything else, it’s worth sorting out which of these you’re actually dealing with, because the correct response is different for each:
- A trespasser entered without permission and hasn’t tried to establish any ongoing claim to live there — someone camping on vacant land for a few nights, for example. Montana’s criminal trespass statute, Mont. Code Ann. § 45-6-203, generally allows law enforcement to remove a straightforward trespasser who refuses to leave when asked.
- A squatter has moved in and stayed, often long-term, sometimes acting as though they have a right to be there — fixing up the place, receiving mail, telling neighbors they live there. This is the situation that can eventually intersect with adverse possession law, and it’s not one you can resolve with a phone call to the sheriff.
- A holdover tenant actually had a lease at some point and simply didn’t leave when it ended. This isn’t a squatter situation at all — it’s a landlord-tenant matter, and it has to go through the normal eviction process for a tenant who’s overstayed.
Getting this distinction right matters because treating an actual squatter the same way you’d treat an obvious trespasser — say, by physically removing them yourself — can create real legal exposure, which we’ll get to.
What It Actually Takes to Claim Adverse Possession in Montana
Adverse possession is the legal doctrine that lets someone who has occupied land long enough, under the right conditions, eventually claim legal ownership of it. Every state recognizes some version of this, and the specifics vary a lot. Montana’s version, under Mont. Code Ann. § 70-19-411, is on the stricter end nationally, for one specific reason: it demands both time and money from the person trying to claim your land.
To succeed, a claimant generally has to show all of the following, continuously, for a full five years:
- Actual possession — genuinely occupying and using the property, not just claiming to.
- Open and notorious possession — using it visibly, the way an actual owner would, not secretly.
- Exclusive possession — not sharing use of the property with the true owner or the general public.
- Hostile possession — occupying it without the owner’s permission (this is a legal term of art, not a requirement that anyone act aggressively).
- Continuous possession for the entire five-year period — any meaningful gap resets the clock to zero.
Here’s the part that makes Montana unusually demanding: on top of all of that, the claimant must also have paid all state, county, and municipal property taxes assessed against the parcel for that same five-year period. Missing this requirement defeats the claim entirely, even if every other element is satisfied. Montana doesn’t offer a shortcut for a squatter holding a defective or “color of title” deed the way some states do — the five-year-plus-taxes rule applies across the board, deed or no deed.
In practice, this combination is exactly why genuine adverse possession claims are rare in Montana. Most squatter situations never come anywhere close to meeting it — but “rare” isn’t the same as “never,” which is why it’s worth taking a long-term unauthorized occupant seriously rather than assuming time is automatically on your side.
Why “30-Day Squatters Rights” Isn’t a Real Thing
You’ll sometimes hear a claim that a squatter gains some kind of protected status after 30 days. That idea seems to come from a mix-up with landlord-tenant notice periods — Montana’s regular landlord-tenant law does involve 30-day notices in some contexts, but that framework applies to actual tenants with a lease, not to someone who moved into a vacant property uninvited. An unauthorized occupant with no lease and no five years of continuous possession plus tax payments has no special protection at the 30-day mark, or really at any point short of meeting the full adverse possession test above.
What You Cannot Do, Even With a Clear-Cut Squatter
This is the part that surprises a lot of frustrated property owners: even when you’re completely certain someone has no right to be on your property, you can’t simply remove them yourself. Montana law prohibits self-help eviction — changing the locks, shutting off utilities, physically removing someone’s belongings, or forcing them out without going through the proper legal process. This rule applies broadly across landlord-tenant situations, and acting on your own can expose you to civil liability regardless of how clearly you’re in the right about the underlying occupancy.
How to Actually Remove a Squatter in Montana
The correct path depends on which category above you’re dealing with:
For a clear-cut trespasser with no attempt to establish residency — someone who just wandered onto vacant land — contacting local law enforcement under the criminal trespass statute is often enough to have them removed, provided you can show proof of ownership.
For an actual squatter who has moved in and is asserting some claim to be there, the process runs through the courts:
- File a Forcible Entry and Detainer (FED) action in the justice court for the county where the property sits, under Mont. Code Ann. § 70-27-101 and following. You’ll need to show the occupant entered or is holding the property without any legal right.
- Attend the court hearing. Bring your deed or recorded title, along with documentation of the occupation — photos, dates, any prior communication attempting to resolve it.
- If you win, the court issues a writ of restitution. This authorizes removal of the occupant.
- The sheriff, not the property owner and not local police, carries out the physical removal. You deliver the writ to the sheriff’s office, and they handle posting notice and the actual removal if the occupant doesn’t leave voluntarily.
You may see claims online that Montana passed a law in 2025 creating a fast-track removal process for squatters, similar to laws passed in Florida and a few other states. As of this writing, that isn’t settled — there was a bill (Senate Bill 101) introduced in the Montana legislature in early 2025 addressing this, but its status and scope should be confirmed with a current source or an attorney rather than assumed, since this is exactly the kind of detail that changes from one legislative session to the next. Don’t build your removal plan around a law you haven’t personally confirmed is actually in effect.
Practical Steps If You Discover a Squatter
- Document everything before you do anything else — dates, photos, any names you can identify, and how you discovered the occupancy.
- Don’t confront the occupant alone, and don’t attempt to move their belongings or change locks, however tempting that is.
- Contact local law enforcement first to establish whether this is treated as a straightforward trespass or something requiring the FED court process.
- Consult an attorney promptly if there’s any indication the person has been there for an extended period, has been paying property taxes (however unlikely that sounds), or is asserting any claim to residency — the sooner you act, the further you are from ever approaching that five-year threshold.
Why Vacant and Seasonal Properties Are Especially at Risk
Squatting situations in the Flathead Valley tend to cluster around properties that sit unattended for stretches of time — an inherited property nobody’s settled the details on yet, a seasonal cabin used only part of the year, or a rental between tenants that sits vacant longer than expected. Regular property checks, visible signage, and prompt action at the first sign of unauthorized occupancy are the most effective tools you have, precisely because they prevent a situation from ever getting close to Montana’s five-year threshold in the first place.
This is one of the quieter advantages of professional property management for owners who don’t live near their own rental, or who own a second property they can’t check on regularly. Part of what a manager does is simply notice when something’s wrong before it’s been wrong for months. If you own a property in the Flathead Valley that sits vacant for stretches of the year, our property management services include the kind of regular oversight that catches an unauthorized occupant early, rather than five years into a problem you didn’t know you had.
