Squatters Rights in New Hampshire: 20-Year Adverse Possession Law
New Hampshire requires 20 continuous years of open, notorious, hostile, exclusive possession. House Bill 1400 (2024) created a faster court process for removing unauthorized occupants, separate from this adverse possession framework.

Recent Law Changes in New Hampshire
House Bill 1400, signed August 23, 2024 and codified as Chapter 370, created an expedited petition process for removing an "unauthorized occupant" under RSA 540-A:3, IX, effective January 1, 2025 -- faster than the standard landlord-tenant eviction process it's modeled on. This is a removal-process change and does not alter the 20-year adverse possession period.
New Hampshire Adverse Possession Procedures
Making an Adverse Possession Claim in New Hampshire
New Hampshire has no adverse possession statute as such; the claim instead rests on the 20-year statute of limitations for real actions, RSA 508:2, as interpreted by decades of state case law. There is no shortened "color of title plus tax payment" track like some states offer — every claimant must satisfy the full 20 years.
- File a petition to quiet title in the Superior Court for the county where the property sits
- Prove possession was actual, open, notorious, exclusive, hostile, and continuous for the entire 20-year period under RSA 508:2
- Present evidence such as witness testimony, surveys, photographs, and records of improvements, fencing, or maintenance
- Address any evidence that the occupation was permissive, since permission defeats hostility
- Obtain a final decree from the court establishing title, then record it with the county registry of deeds
Under Mastroianni v. Wercinski, a good-faith mistake about where the boundary line actually runs does not defeat a claim — courts ask whether the occupant used the land as an owner would, not whether they intended to steal it.
Defending Against Adverse Possession Claims
New Hampshire property owners, particularly those with rural, wooded, or seasonal parcels common in the state, can take practical steps to prevent a neighbor's use from ripening into a legal claim.
- Walk and inspect property boundaries at least annually, especially undeveloped or camp/lake lots used only seasonally
- Post the property in a manner reasonably likely to come to the attention of intruders
- Keep a current survey on file and compare it against any fences, sheds, or driveways near the boundary
- Put any permitted neighbor use (mowing, gardening, shared driveway) in writing so it cannot later be called hostile
- Act promptly, including sending a written demand or filing suit, once encroaching use is discovered
Any interruption of the encroacher's continuous use — even a single acknowledgment that the true owner holds title — can restart the 20-year clock.
Removing Squatters in New Hampshire
- For a recent, clear-cut trespasser with no claim of right, contact local police; unauthorized entry into or remaining on property can be charged as criminal trespass under RSA 635:2
- For an unauthorized occupant who doesn't qualify as a trespasser, file the expedited petition created by RSA 540-A:3, IX (effective January 1, 2025), which is faster than a standard landlord-tenant case
- Where the occupant claims tenant status instead, file a landlord-tenant action in the Circuit Court – District Division for the county where the property is located
- Attend the scheduled hearing and, if the court rules for the owner, obtain a writ of possession
- Have a sheriff's deputy serve and execute the writ if the occupant still refuses to leave
New Hampshire law does not permit self-help evictions — changing the locks, removing belongings, or shutting off utilities can expose the owner to civil and even criminal liability, regardless of how clearly unauthorized the occupant is.
Notable New Hampshire Adverse Possession Cases
Hewes v. Bruno (1981)
121 N.H. 32, 424 A.2d 1144 (1981)
The New Hampshire Supreme Court held that a claimant's subjective intent to possess land adversely is irrelevant; what matters is whether the occupant treated the land as their own for the full statutory period. The court repudiated an older rule that had barred someone holding under a defective deed from also claiming adverse possession.
Mastroianni v. Wercinski (2009)
158 N.H. 380, 965 A.2d 1139 (2009)
The court held that a landowner who occupies land up to a mistaken boundary line, honestly but wrongly believing it to be the true line, can still satisfy the hostility element of adverse possession and gain title up to that occupied line.
O'Hearne v. McClammer (2012)
163 N.H. 430, 42 A.3d 834 (2012)
The New Hampshire Supreme Court applied the related doctrine of boundary by acquiescence, holding that a line neighbors have treated as the true boundary for the statutory period can prevail over the description in the parties' deeds.
Frequently Asked Questions About New Hampshire Adverse Possession
How long must someone occupy my property in New Hampshire before they can claim adverse possession?
New Hampshire requires 20 continuous years of actual, open, notorious, exclusive, and hostile possession under RSA 508:2. Unlike some states, New Hampshire does not offer a shortened period for claimants who have color of title and pay property taxes — the full 20 years applies either way. Stories about acquiring rights after 30 days of occupancy are simply false.
Does paying property taxes matter for a New Hampshire adverse possession claim?
Not directly. New Hampshire's adverse possession doctrine, built on RSA 508:2 and case law rather than a dedicated statute, does not require the possessor to have paid taxes on the property. Tax records are still useful evidence of how openly and consistently someone treated the land as their own, but they are not a required element as they are in some other states.
What does "hostile" possession mean under New Hampshire law?
It does not mean ill will or aggression. Under cases like Mastroianni v. Wercinski, hostile simply means the occupant used the land without the owner's permission, even if that use began from an honest mistake about where the boundary line actually was.
Can a boundary line my neighbor and I have always used override our deeds?
It can. New Hampshire recognizes boundary by acquiescence, under which a line that neighbors have treated as the true boundary for 20 years can control over a conflicting description in their deeds, as the Supreme Court confirmed in O'Hearne v. McClammer.
Can someone claim adverse possession of state or municipal land in New Hampshire?
No. Land owned by the State of New Hampshire, its municipalities, or the federal government cannot be acquired through adverse possession. This matters in a state where a substantial share of land, including White Mountain National Forest and state forests, is publicly owned.
How do I legally remove a squatter from my New Hampshire property?
If the person is a clear trespasser with no claimed right to be there, you can involve local police under New Hampshire's criminal trespass statute, RSA 635:2. If they assert some right to remain, you generally need to file a landlord-tenant case in the Circuit Court – District Division and obtain a writ of possession. Self-help measures like changing the locks are illegal in New Hampshire.
Can I have a squatter removed by police in New Hampshire?
New Hampshire police can arrest a squatter for criminal trespass under RSA 635:2 when the person knowingly entered or is remaining without permission and has no plausible claim of tenancy, such as a stranger found in a vacant house shortly after breaking in. If the occupant asserts any claim to being there, like a prior lease, guest status, or implied tenancy, police typically step back and the matter becomes civil. A 2024 law (HB 1400, effective January 1, 2025, now codified at RSA 540-A:3, IX) lets owners petition the circuit court's district division for an expedited order removing a true non-tenant unauthorized occupant, with a hearing required within five days, faster than New Hampshire's standard landlord-tenant eviction process under RSA 540. Regardless of the route used, self-help removal such as changing locks or shutting off utilities remains illegal; only a sheriff's deputy executing a court order may lawfully remove an occupant who refuses to leave.
