Squatters rights in Massachusetts almost never mean what the phrase suggests. Most sellers who search for it are not worried about someone quietly claiming ownership after twenty years. They have an actual occupant in an actual house, and they want to know whether they can simply have that person removed. The honest answer depends entirely on one fact: did that person ever have your permission to be there. That single question decides which Massachusetts law applies, how fast you can act, and whether you need a court order or a phone call to the police.
What Squatters Rights in Massachusetts Actually Means
“Squatters rights” as a legal term refers to adverse possession, a doctrine that lets someone eventually claim ownership of land they have used openly and without permission for a long, specific period. Massachusetts law is explicit that adverse possession and trespassing are not the same thing, and under Massachusetts General Laws chapter 260, section 21, a claim like that requires actual, open, exclusive and continuous use for 20 years before anyone could even file it. If you are selling a house with someone living in it right now, you are not dealing with a 20 year ownership claim. You are dealing with a possession problem, and possession problems split into two very different routes depending on how the person got in.
Route One: The Occupant Once Had Your Permission
If the person living there ever had your consent, even informally, a relative you let move in, a renter on a handshake, an ex who stayed after a breakup, Massachusetts law treats them as a tenant for removal purposes no matter what you call the arrangement. Specifically, someone who “rightfully entered the premises at the commencement of the tenancy or occupancy” and remains after that permission ends is excluded from the trespass statute entirely under Massachusetts General Laws chapter 266, section 120, which says plainly that the owner “may recover possession thereof only through appropriate civil proceedings.” That means no self-help and no police removal as trespassers. You serve a notice to quit, then file the same summary process eviction case under chapter 239 that a landlord uses against a nonpaying tenant, and you wait on the same court calendar everyone else does.
Route Two: The Occupant Never Had Your Permission
If the person broke in, moved into a vacant house you own, or otherwise entered without ever asking you, that trespass exclusion does not apply to them, because they never “rightfully entered” in the first place. Chapter 266, section 120 lets you or the police tell that person to leave, and a police officer can arrest someone who is “found committing such trespass” after being forbidden to stay, either by a direct warning or a posted notice. In practice, officers responding to a true break-in squatter with no claim of tenancy will often act on that statute directly rather than sending you to housing court first.
The complication is that Massachusetts also bars an owner from using force to retake property on their own, under chapter 184, section 18, which requires that any attempt to recover possession go through chapter 239 “or such other proceedings authorized by law.” The trespass arrest under chapter 266 is one of those other authorized proceedings, so it is not a conflict, but it means the outcome in practice often turns on how clearly you can show the officer on scene that this person never had any right to be there. Photos, a prior vacancy inspection, mail addressed to someone else, and a record of when you first discovered the occupant are what make that case fast rather than disputed.
Squatter or Tenant: Which Route Applies
| Once had your permission | Never had your permission | |
|---|---|---|
| Legal category | Tenant at sufferance | Trespasser |
| Who acts | You, through the courts | Police, after a warning or posted notice |
| Mechanism | Notice to quit, then a chapter 239 summary process case | Chapter 266, section 120 criminal trespass |
| Typical pace | Weeks to a few months, same as any eviction | Can be same-day once the officer is satisfied no permission was ever given |
| Where it gets slow | Any ambiguity about whether permission was ever given | Any ambiguity about whether permission was ever given |
The row that repeats is not an error. Both routes hinge on the same fact, and an occupant who wants to stay will almost always claim the more protective category, meaning they will say they had your permission even where you say they did not. That is exactly the kind of dispute a Massachusetts housing court or a landlord-tenant attorney sorts out, and it is not one to guess your way through, especially before you have a buyer and a closing date riding on the answer.
Selling While the Occupant Issue Is Still Open
A buyer using a mortgage generally needs the seller to deliver clear possession, either vacant or with a lease the new owner can step into, at or before closing, so an unresolved occupant can stall or sink a financed sale regardless of which route eventually applies. In the deals we have closed, landlord and tenant problems of exactly this kind account for roughly 15 percent of the sellers who come to us, and a large share of them have already tried one approach that did not work before they called. If going through the court process or waiting on a police response is not realistic on your timeline, selling as-is to a buyer who does not need a mortgage removes that financing dependency, and in some cases a negotiated move-out, what the industry calls cash for keys, can resolve a tenant-category occupant’s departure faster and for less than a full eviction case runs. If the occupant in your situation is unquestionably a tenant rather than someone who broke in, the full eviction timeline walks through each step chapter 239 actually requires. You can also request a cash offer to see what selling with the situation disclosed, rather than resolved first, would actually net you.
Questions Sellers Ask About Squatters in Massachusetts
Can I just change the locks while they are out? No. Massachusetts bars an owner from retaking possession by force or self-help regardless of which category the occupant falls into, and doing so can hand them a legal claim against you even if they had no right to be there in the first place.
Does it matter how long they have been there? For removal purposes, not much, since the 20 year threshold is for an ownership claim, not for how fast you can act. A person who moved in without permission six weeks ago is handled the same way under the trespass statute as one who has been there six years.
What if I am not sure whether they ever had my permission? That uncertainty is exactly why this is a question for a landlord-tenant attorney or the police rather than a guess, since acting on the wrong category can cost you time, a dismissed case, or exposure to a claim.
Will the police just remove someone for me? Sometimes, if the facts clearly show the person never had any right to be there. Where it is unclear, officers commonly decline to act and direct the owner to housing court instead.
This explains how Massachusetts law sorts a squatter from a holdover tenant, not what to do about your specific occupant. A Massachusetts landlord-tenant attorney can tell you quickly which category you are dealing with and what evidence to gather before you act.
