The Five-Year Clock on a Boundary Fight

Posted on August 13th, 2026

Montana Sets a Short Window for Adverse Possession Claims

Montana allows someone to gain legal title to land they do not own by treating it as their own for long enough, a doctrine that surprises many property owners the first time they encounter it. Under Montana Code Annotated Section 70-19-411, a claimant must show open, continuous possession of the disputed land for five years, one of the shortest periods among the states, and must also have paid all state, county, and municipal taxes assessed against that property for the entire five-year period. Missing even a single year of that continuous possession or tax payment history resets the entire calculation. Selling the property, even briefly interrupting occupancy, or a temporary absence longer than expected can each restart the five-year clock from zero.

Why the Tax Requirement Changes Everything

That second requirement often becomes the single deciding factor in a Montana boundary dispute. A neighbor who has used a strip of land for a decade, built a fence on it, or maintained it as their own still generally has to show tax payments tied specifically to that land, not just to their own separately described parcel, which is a detail many claimants overlook entirely. This tax requirement makes adverse possession claims harder to establish quietly than in many other states, which can work strongly in favor of the property owner defending the claim. Many claimants discover, once a dispute reaches court, that they never actually paid taxes tied to the specific parcel in question. Tax records are public and relatively easy to obtain, which makes this element of a claim one of the first things worth investigating.

What Evidence Shapes These Disputes

Boundary disputes and adverse possession claims in Montana typically turn on a combination of physical and documentary evidence, including:

  • Survey records and legal property descriptions going back as far as possible
  • Tax assessment and payment records for the disputed strip
  • Photographs showing fences, structures, or landscaping over time
  • Witness accounts of how long a disputed use has continued without interruption

A Billings Real Estate Litigation lawyers team typically starts by pulling survey and tax records before the dispute reaches a courtroom, since these records often resolve the factual questions before litigation even begins. This early groundwork can also reveal whether a claim has any real chance of succeeding before either side spends significant money on litigation.

Defending an Ownership Interest

Property owners facing a claim against their land, or trying to establish rights to land they have used for years, need a clear and thorough record built well before a dispute becomes formal. The team at Silverman Law Office, PLLC represents property owners in these boundary and title disputes, working through survey history and tax records to build the strongest possible position. A dispute that looks purely factual on the surface often turns out to hinge on a handful of specific documents once the case is properly investigated. Old survey markers and tax assessor records often hold the key facts that decide these disputes, sometimes going back decades before the current owners ever purchased the property.

Acting Before a Dispute Escalates

Waiting until a neighbor files a formal claim often means starting from a weaker position than acting early, since evidence like fence lines and tax records can be easier to gather before a dispute turns adversarial. A Billings Real Estate Litigation lawyers team can review a property’s history even before a formal dispute arises, flagging any boundary issue that might need attention. A routine survey when refinancing or selling a property is often the moment these issues first come to light.
