How to Prove or Defend Against Adverse Possession Claims in Massachusetts Land Court

Current as of: September 16, 2026 Zoning, Land Use & Boundary Disputes Massachusetts
To successfully claim adverse possession in Massachusetts, you must prove 20 years of continuous, open, notorious, exclusive, and adverse use of the land. However, this legal doctrine cannot be used against municipal land, state property, or formally 'Registered Land.'

Discovering that your property line is not where you thought it was can cause massive headaches, especially when a neighbor has been using a portion of your land for decades. Adverse possession, sometimes called 'squatter's rights,' is a legal doctrine that allows someone to claim ownership of land they do not legally own, provided they meet extremely strict criteria over a long period. In Massachusetts, litigating these boundary shifts requires highly specialized knowledge, as cases are typically handled by the state's unique Land Court system.

The 20-Year Standard in Massachusetts

Under Mass. Gen. Laws ch. 260, § 21, the statute of limitations for the recovery of land in Massachusetts is exactly 20 years. To strip a legal owner of their title, the person claiming adverse possession must prove that their use of the land was continuous for the full 20 years, open (visible to everyone), notorious (well-known), exclusive (the true owner wasn't using it), and adverse (without the true owner's permission).

Misplaced Fences and Extended Paved Driveways

The most common adverse possession cases arise from simple mistakes made decades ago. If a neighbor erects a fence three feet over the property line and maintains that enclosed space for 20 years, they might legally claim that strip of land. Similarly, paving a driveway that encroaches onto an adjoining lot can satisfy the 'open and notorious' requirement. A critical precedent was set in Kendall v. Selvaggio, 413 Mass. 619 (MA Supreme Judicial Court 1992), which established that a mutual mistake about where the boundary line actually lies does not defeat a claim of adverse possession; the intent to hold the land as one's own is enough to meet the 'adverse' requirement.

Maintaining a Neighbor's Lawn

It is important to note that casual use is rarely enough. Simply mowing a strip of grass or walking across a neighbor's wooded lot occasionally does not typically satisfy the strict requirements of exclusivity and permanent occupation. Massachusetts courts look for permanent improvements, enclosures (like fences or walls), or substantial landscaping that clearly signals a claim of absolute ownership.

Strict Exemptions Under Massachusetts Law

Even if a neighbor has occupied a piece of land for 50 years, certain types of property are completely immune to adverse possession in Massachusetts.

Municipal, State-Owned, or Registered Land

You cannot claim adverse possession against land owned by the state, a city, or a town (such as public parks or conservation land). More importantly for residential homeowners, Massachusetts has a unique dual system for recording land titles: Recorded Land and Registered Land. If a property went through the strict Land Court registration process, it is considered 'Registered Land' (or Torrens land). Under Mass. Gen. Laws ch. 185, § 53, no title to Registered Land can ever be acquired by adverse possession. If your deed says 'Registered Land,' your property lines are legally bulletproof against squatter claims.

Step-by-Step Guide to Proving or Defending a Claim

Resolving these disputes requires a precise legal strategy.

  • Step 1: Hire a Licensed Land Surveyor. Before taking any legal action, you must hire a professional Massachusetts land surveyor to conduct an instrument survey. This will definitively show where the deeded boundary lies and the exact square footage of the encroachment.
  • Step 2: Check the Registry of Deeds. Your attorney will pull the title history to confirm if the land is Recorded or Registered, which immediately dictates if adverse possession is even possible.
  • Step 3: Send a Notice to Prevent Acquisition. If you catch a neighbor encroaching before the 20 years are up, your lawyer can serve them with a formal 'Notice to Prevent Acquisition of Easement' or file a trespass claim to reset the 20-year clock.
  • Step 4: File in Massachusetts Land Court. To formalize the boundary shift or evict an encroacher, your attorney will file a lawsuit. You will likely use a document akin to Form Civil Cover Sheet, Massachusetts, Land Court, Civil Action Cover Sheet, filing the case directly at the Massachusetts Land Court, Boston, which has specialized jurisdiction over these complex title matters.

Legal Costs in Boundary Disputes

Adverse possession cases are notoriously expensive because they are heavily fact-dependent. Surveyors generally charge between $1,500 and $3,500 for a detailed boundary plan. Because these cases often require digging up historical aerial photos and tracking down previous owners to testify about the 20-year timeline, attorney fees can easily range from $10,000 to $30,000+ if the case goes to a full trial in the Land Court.

Frequently Asked Questions (FAQ)

Can a tenant claim adverse possession?

No. By signing a lease and paying rent, a tenant acknowledges the landlord's ownership. Therefore, their possession is with permission, which completely destroys the 'adverse' requirement of the law.

What is 'tacking' in adverse possession?

Tacking allows successive owners to combine their years of occupation to reach the 20-year requirement. If the previous owner encroached for 15 years, and you buy the house and encroach for 5 more years, you can 'tack' the time together to claim the land.

Does giving permission stop adverse possession?

Yes. The most effective defense against adverse possession is explicitly giving the person written permission to use the land. If they are there with your documented permission, their use is not 'adverse' or 'hostile,' and they can never claim ownership.

Can you adversely possess an easement?

Yes, but it is called a 'prescriptive easement.' If someone uses your driveway for 20 years to access their own property without your permission, they don't gain ownership of the land, but they gain a permanent legal right to continue using the driveway.
