Massachusetts Squatters Rights and Adverse Possession Laws (2026)

In Massachusetts, a squatter must occupy property continuously for 20 years before gaining any legal claim under Mass. Gen. Laws ch. 260, § 21. Property owners who discover an unlawful occupant can remove that person through a summary process action filed in Housing Court or District Court under Mass. Gen. Laws ch. 239.

Adverse Possession in Massachusetts: Period and Elements

Massachusetts applies a single, uniform 20-year adverse possession period under Mass. Gen. Laws ch. 260, § 21. The statute of limitations runs against the true owner's right to bring an action to recover land. Once 20 years pass without the owner asserting that right, the occupant may petition a court to quiet title in their favor.

Unlike many states, Massachusetts provides no shorter period for claimants who hold color of title (a defective deed or other written instrument). The same 20-year clock applies regardless of whether the occupant has paperwork. Massachusetts also imposes no requirement that the occupant pay property taxes during the occupation period.

To succeed on an adverse possession claim in Massachusetts, the occupant must prove that their possession was:

• Actual. The occupant must physically use the land in a manner consistent with its nature, such as maintaining a yard, making improvements, or farming.
• Open and notorious. The use must be visible and obvious, giving a reasonable owner notice that someone is claiming the land.
• Exclusive. The occupant must control the property without sharing possession with the general public or the true owner.
• Continuous. Possession must be uninterrupted for the full 20-year period. Tacking (adding together the periods of successive occupants in privity with one another) is permitted under Massachusetts case law. Ottavia v. Savarese, 338 Mass. 330, 155 N.E.2d 432 (1959).
• Hostile (under claim of right). The occupant must possess the land without the owner's permission and with the intent to claim it as their own. Kershaw v. Zecchini, 342 Mass. 318, 173 N.E.2d 624 (1961).

Massachusetts courts have consistently applied these elements. The burden of proof rests on the adverse claimant to establish each element by clear proof. Mendonca v. Cities Service Oil Co., 354 Mass. 323, 237 N.E.2d 16 (1968).

The Registered-Land Exception

One of the most significant features of Massachusetts adverse possession law is the registered-land exception. Under the Land Court Registration Act, Mass. Gen. Laws ch. 185, title to land registered in the Land Court system is conclusive and indefeasible. Adverse possession cannot run against registered land. A certificate of title issued by the Land Court constitutes absolute proof of ownership, and no prescriptive or adverse claim can defeat it.

Property owners who have registered their land through the Land Court therefore enjoy complete immunity from adverse possession claims, regardless of how long an occupant has been present. Owners of unregistered (recorded) land do not have this protection and remain subject to the 20-year rule.

The Nonprofit Land Conservation Exception

Mass. Gen. Laws ch. 260, § 21 also excepts nonprofit land conservation corporations and trusts. The 20-year bar does not apply to an action brought by or on behalf of a nonprofit land conservation entity to recover land or interests in land held for conservation, parks, recreation, water protection, or wildlife protection purposes. This exception preserves the ability of conservation organizations to protect permanently restricted open land from adverse possession claims.

How to Remove a Squatter in Massachusetts

A squatter who has not yet satisfied the 20-year adverse possession period holds no legal title and no legal right to remain on the property. Massachusetts law, however, generally requires a property owner to obtain a court order before physically removing an occupant. Self-help eviction (changing locks, removing belongings, or shutting off utilities to force someone out) is illegal under Massachusetts law and can expose the owner to civil liability.

Step 1: Do Not Use Self-Help

Massachusetts law prohibits landlords and property owners from removing occupants by force or without legal process. Even a squatter with no tenancy agreement is entitled to court process before removal.

Step 2: File a Summary Process Complaint

The primary legal mechanism for removing a squatter in Massachusetts is a summary process action under Mass. Gen. Laws ch. 239. The property owner (plaintiff) files a complaint in Housing Court or District Court for the county where the property is located. The complaint must identify the property and state the grounds for removal.

For a squatter who never had any tenancy, the grounds are unlawful detainer: the occupant is on the property without right or title.

Step 3: Serve the Occupant

Once the complaint is filed, the court issues a summons. The summons and complaint must be served on the occupant at least seven days before the hearing date under ch. 239. Service is typically made by a deputy sheriff or constable.

Step 4: Attend the Hearing

The case is heard on a short schedule. If the occupant does not appear or cannot establish a legal right to remain, the court enters judgment for the property owner. If the occupant raises an adverse possession defense, the court will evaluate whether the 20-year period has been satisfied.

Step 5: Obtain and Execute the Execution

After judgment enters in the owner's favor, the court issues an execution. The owner must wait 10 days after judgment before the execution can issue (unless the court waives the stay). A deputy sheriff or constable then carries out the removal, which may include a lockout and supervised removal of the occupant's belongings.

No Expedited Removal Law

As of May 2026, Massachusetts has not enacted a dedicated expedited squatter-removal statute. Several states enacted such laws in 2024, but the Massachusetts Legislature passed no comparable measure in 2024 or 2025. Summary process under ch. 239 remains the sole civil pathway for removal, and it typically resolves within a few weeks of filing if the occupant does not contest the action.

Involving Law Enforcement

If a squatter is a clear trespasser who entered the property by breaking in and has been present for a very short time, the property owner may contact local police and ask whether a criminal trespass complaint is appropriate under Mass. Gen. Laws ch. 266, § 120. Police discretion varies, and law enforcement may still defer to the civil summary process route if there is any ambiguity about the occupant's status.
