Squatter Rights in Massachusetts: The 20-Year Rule and Removal

Squatters’ rights in Massachusetts come from the state’s adverse possession law, which lets someone who occupies another person’s land for 20 continuous years eventually claim legal title — but only if they meet five strict requirements and the property isn’t registered with the Land Court. Until a squatter wins that claim in court, they have no ownership, and the legal owner can remove them, but only through the formal eviction process. Self-help removal is illegal and expensive.

What a Squatter Has to Prove

Under Mass. Gen. Laws ch. 260, § 21, a property owner has 20 years to sue to recover land from an unauthorized occupant. Miss that window and the owner loses the right to sue.¹ The clock starts the moment the occupation begins and runs continuously from there.

Twenty years alone doesn’t give anyone title. The occupant also has to prove five separate elements for the full period, and failing on any one of them defeats the claim.²

Actual possession. The squatter physically uses the land the way an owner would — mowing, maintaining, planting, repairing. Occasional visits or storing a few items don’t qualify. Paying property taxes helps as evidence but isn’t enough on its own.
Open and notorious. The use has to be visible enough that an owner inspecting the property would notice it. Hidden or concealed occupation fails.³
Exclusive. The squatter holds the land alone. If the real owner keeps using the property for any purpose, or if the space is shared with other squatters or the public, exclusivity fails.
Non-permissive (hostile). The occupation happens without the owner’s permission. Any agreement — a lease, a verbal arrangement, even a casual “you can stay for now” — turns the use permissive and kills the claim. Permitted use never ripens into ownership.
Continuous. Twenty unbroken years. Seasonal use can count if it matches how an owner would normally use that kind of property (a summer cabin, for example), but moving out and coming back later breaks the chain.

Even after 20 years, a squatter doesn’t automatically own anything. They have to file a quiet title action in the Land Court or Superior Court and prove each element by clear and convincing evidence, a higher standard than most civil cases use.³

Registered Land Is Immune

The single most important thing for a Massachusetts property owner to check: is your land registered? Under Mass. Gen. Laws ch. 185, § 53, no title to registered land can be acquired through adverse possession, ever.⁴ A squatter could live on registered land for 50 years and still have no legal path to ownership.

Not all Massachusetts property is registered. Most land uses the ordinary recording system at the county Registry of Deeds. Registered land is confirmed through the Land Court and comes with a Certificate of Title rather than an ordinary recorded deed. If yours is registered, adverse possession is simply off the table.

Tacking: Why a New Squatter Can Still Be a Problem

Massachusetts allows successive occupants to combine their years toward the 20-year total, a doctrine called tacking. Mass. Gen. Laws ch. 260, § 22 lets time held by a predecessor count for the current occupant.⁵ If one squatter holds property for 12 years and hands it off to another who stays for 8, the second occupant can potentially claim the full 20.

Tacking requires privity — a real connection between the successive occupants, like a sale, an inheritance, or a deliberate handoff. Someone who wanders onto abandoned land after the previous occupant left can’t piggyback on the earlier years. The chain has to be unbroken and intentional.

How to Remove a Squatter

Anyone who enters or remains on your property after being told to leave can be charged with criminal trespass under Mass. Gen. Laws ch. 266, § 120.⁶ In practice, though, police often decline to act once an occupant claims any right to be there, and they refer the owner to the civil courts. Owners who discover a squatter early have a better chance of getting law enforcement involved than those who wait.

The formal removal procedure is called summary process, governed by Mass. Gen. Laws ch. 239.⁷ It runs in a set order:

Serve a written Notice to Quit identifying the occupant, the property address, and the date by which they must leave.⁸
If the occupant hasn’t left by that date, file a summons and complaint in Housing Court ($135 filing fee) or District Court ($195). A hearing is usually scheduled within a few weeks.⁹¹⁰
If the court rules for the owner, it issues a judgment for possession and an execution document authorizing physical removal.
Only a constable or deputy sheriff can carry out the move-out, and they must give the occupant at least 48 hours of written notice before doing so. The officer can also arrange storage of any belongings left behind.

Don’t Change the Locks

Massachusetts prohibits owners from taking removal into their own hands. Under Mass. Gen. Laws ch. 186, § 14, an owner who tries to force out an occupant without going through the courts faces criminal penalties of up to $300 in fines or six months in jail.¹¹ No lock changes, no shutting off utilities, no removing belongings, no intimidation.

The civil side is worse. An occupant who is illegally locked out or has utilities cut can sue for actual damages or three months’ rent, whichever is greater, plus attorney’s fees.¹¹ Owners frustrated by the pace of court sometimes try self-help anyway. It almost always costs more than the eviction would have.

Protecting the 20-Year Clock

Anything an owner does to reassert control resets the clock. Filing a suit to recover the land or physically re-entering and retaking the property both start the count over. So does any gap in the squatter’s occupancy — if they leave and come back, those earlier years don’t add up.

For an owner who suspects a possession claim may be brewing, documentation matters. Written demands to vacate, records of visits to the property, receipts for maintenance you performed, and photographs dated over time all show either that the occupation wasn’t continuous or that it wasn’t exclusive. Property tax records and utility bills back up who has actually carried the property. Neighbor testimony can go either way, so the value of a written, dated evidence trail is hard to overstate. Any single interruption you can prove breaks the continuity a squatter needs.
