Squatters’ Rights in Massachusetts: Adverse Possession and Removal

The phrase “squatters’ rights” describes adverse possession, a property doctrine covered within Massachusetts landlord-tenant law. This article explains what a squatter can and cannot claim in Massachusetts, the strict conditions the law imposes before occupation ripens into ownership, and the court process an owner uses to recover possession. It covers residential and unimproved land generally; it does not address boundary-line disputes between neighbors, which follow the same rules but turn on their own facts.

What “squatters’ rights” means in Massachusetts

A squatter is someone who occupies property without the owner’s permission and without a lease. Occupying property that belongs to someone else is not, by itself, a crime in Massachusetts. Trespass and related offenses exist, but a live occupancy dispute over who may remain in a dwelling is treated as a civil matter that the property owner resolves in court. That distinction is why police often decline to physically remove an occupant and instead point the owner toward the eviction process.

Adverse possession is the narrow path by which long, open occupation can eventually become legal ownership. Under Mass. Gen. Laws ch. 260, § 21, an action to recover land must be brought within 20 years after the right of entry first accrued. Once that 20-year window closes, the record owner loses the ability to eject the occupant, and the occupant can ask a court to confirm title. The same 20-year period appears in the Justia mirror of the statute.

Adverse possession is uncommon and hard to prove. A person who has occupied a house for a few months, or even a few years, has no ownership claim at all. The doctrine exists mainly to settle old, unclear boundaries and long-abandoned parcels, not to reward recent squatting.

The elements of adverse possession

Massachusetts courts require an occupant to prove every element of adverse possession, and the occupant carries the burden. The use of the land must be:

• Open and notorious, visible enough that a reasonable owner inspecting the property would notice it.
• Exclusive, the occupant uses the land as an owner would, not shared with the true owner or the general public.
• Adverse (hostile), without the owner’s permission. A tenant, guest, or anyone using land with consent can never adversely possess it.
• Continuous, uninterrupted for the full statutory period.

Continuity runs for the full 20 years set by Mass. Gen. Laws ch. 260, § 21. Seasonal or sporadic use usually breaks continuity, though use consistent with the character of the land can qualify.

An occupant does not have to occupy the whole 20 years personally. Successive occupants who pass the property between them in an unbroken chain can combine their periods, a concept called tacking, as long as each hand-off connects the possessors. But a gap in which the owner retakes control resets the clock.

When the 20-year clock can pause or extend

The 20-year period is not always rigid. Mass. Gen. Laws ch. 260, § 22 gives extra time when the person entitled to recover the land was under a legal disability, such as being a minor or legally incapacitated, when the right of entry first accrued. In those situations the owner (or their successor) gets additional time to act after the disability is removed, so occupation that looks like it has run past 20 years may not have.

An owner can also stop the clock before 20 years elapse. Bringing a court action to recover possession, or otherwise reasserting control, interrupts the continuity the occupant needs. Because the occupant must prove an unbroken 20 years, any documented interruption by the owner is a complete answer to the claim.

Removing an occupant: summary process, not self-help

Massachusetts does not allow property owners to remove occupants by changing the locks, shutting off utilities, or using force. Possession is recovered through the courts using a lawsuit called summary process. Mass. Gen. Laws ch. 239, § 1 lets an owner bring summary process against a person who holds possession of land or tenements without right, which is the category most squatters fall into.

The court process runs on a set of fixed dates, and missing them can get the case dismissed, according to the Massachusetts Court System’s eviction filing guide.

1. End any tenancy first, if one exists

   If the occupant ever had permission and became a tenant at will, that tenancy is terminated with a written Notice to Quit before an eviction can proceed. Under Mass. Gen. Laws ch. 186, § 12, a no-fault notice must give at least a full rental period (commonly 30 days), while a termination for nonpayment of rent gives the tenant 14 days. A pure trespasser who never had permission does not have a tenancy to end.

2. Prepare and serve the Summons and Complaint

   The owner buys the Summary Process Summons and Complaint form from the clerk’s office of the District, Boston Municipal, or Housing Court and hires a sheriff or constable to serve it on the occupant. The form is not filed online.

3. File with the court and pay the fee

   After service, the owner files the notice, the summons and complaint, and the return of service by the entry date, which falls between 7 and 30 days after the service date. As of 2026, the filing fee is $120 in Housing Court and $180 in District or Boston Municipal Court, plus a $15 surcharge, per the Massachusetts Court System.

4. Attend the trial and obtain a judgment

   Both sides appear on the trial date, usually about 10 days after the entry date. If the owner proves the right to possession, the court enters judgment. Only after judgment, and after the appeal period, does the court issue an execution that a sheriff uses to physically remove the occupant.

Because Housing Courts hear only housing cases and offer Housing Specialists who help resolve disputes, many owners file there when the property qualifies. Commercial (non-residential) evictions cannot be filed in Housing Court.

Pending legislation and protecting your property

Massachusetts law on squatters may change. A bill numbered H.1802, “An Act addressing squatter’s rights,” is pending before the current General Court and proposes stronger tools for owners facing unauthorized occupants. Like most bills, it may be amended or may not pass, so the summary process route described above remains the governing procedure until any new law takes effect.

Owners reduce the risk of both squatting and adverse possession by staying visibly connected to their property. Paying property taxes, inspecting vacant parcels, promptly addressing unauthorized entry, and documenting any permission granted to use the land all undercut the elements an adverse possessor would need to prove. Where occupation is already underway, acting before informal use hardens into a claim preserves the owner’s options.
