In Western Montana, criminal trespass is a seasonal offense. The calls arrive in the fall, they involve hunters far more often than anyone else, and the defendant is usually someone who is genuinely surprised to be charged. They believed they were on public land, or on land they had permission to be on, and they have a phone screenshot they think settles it.
These cases are worth taking seriously, both because the consequences reach past the criminal penalty and because the underlying facts are more contestable than most people assume.
The Boundary Is a Fact, Not an Assertion
The heart of most trespass cases is a single question: where does the property line actually run, and was the defendant on the wrong side of it?
That is a factual question with real evidence behind it, including surveys, recorded legal descriptions, and county records. What it is not is a matter of what the landowner believes. Boundary beliefs in rural Montana are frequently inherited, occasionally wrong, and sometimes based on a fence built decades ago in a location nobody has verified since.
A landowner's sincere conviction that you were on their ground is the beginning of the inquiry. It is not the end of it.
About That Mapping App
Nearly every hunter we talk to has a mapping app, and nearly every one of them believes it establishes where they were standing. It is useful evidence. It is not authority.
Parcel data in these apps comes from public records that are sometimes outdated, sometimes imprecise at boundaries, and sometimes wrong about ownership that has changed. Combine that with GPS accuracy that degrades in timbered draws and steep country, and a screenshot showing you fifteen yards inside public land is considerably less conclusive than it appears on the screen.
Save it anyway. Save the whole track log, not the single screenshot, because the track is far more informative than a snapshot of one moment.
Permission Cases
A large share of these charges involve someone who had permission, or thought they did. Permission granted verbally last season, permission from a lessee rather than the owner, permission from one co-owner, permission that was withdrawn without the hunter being told, or land that changed hands over the summer.
These are defensible situations, and they are also situations where the evidence lives in text messages and call logs that people delete. Preserve them before anything else.
Access and Corner Crossing
Montana has genuine, unresolved tension around access to public land locked behind private parcels, and corner crossing sits in the middle of it. This is an actively contested area rather than a settled one.
The practical implication for someone facing a charge is that the legal landscape here is not as fixed as an angry landowner may tell you at the scene. It is worth having someone look at the specific facts rather than accepting a confident characterization from the person who called law enforcement.
Why It Is More Than a Fine
The criminal penalty is often not the biggest issue. A trespass conviction can carry implications for hunting privileges, which for many Montanans matters far more than the fine does. It also produces a criminal record that shows up in background checks that have nothing to do with hunting.
That combination is why resolving these quickly, without examining whether the underlying boundary claim holds up, is usually a mistake.
What to Do at the Scene
- Do not argue the boundary with the landowner. Nothing good comes of it and it can escalate the situation.
- Save your GPS track log, not just a screenshot, along with time stamps.
- Photograph what was posted, including where signage was and was not present.
- Preserve permission evidence, meaning texts, call logs, and names.
- Do not give a detailed statement about where you thought you were before you have advice.
