Squatters’ rights in NH come from a single idea: if someone occupies land without permission for 20 unbroken years and meets a strict set of conditions, New Hampshire law can transfer ownership to them. The rule is called adverse possession, and most claims fail because the occupant can’t prove every element for the full two decades. For property owners, the practical takeaway is simpler. You cannot change the locks or throw a squatter’s belongings out, but you can stop the 20-year clock cold with the right paperwork, and you can remove the occupant through a formal court process.
The 20-Year Rule and What a Squatter Must Prove
New Hampshire’s adverse possession doctrine is almost entirely judge-made. The only statutory piece is RSA 508:2, which gives a property owner 20 years to bring an action to recover real estate.1New Hampshire General Court. New Hampshire Revised Statutes Section 508:2 – Real Actions Once that window closes, the owner is barred from suing, and the occupant can ask a court to recognize them as the new owner.
Courts have spelled out what the occupant must prove for every day of those 20 years:
- Actual possession. The person must physically use the land the way a typical owner would: living on it, farming it, maintaining it, or improving it. Visiting now and then or storing a few items is not enough.
- Open and notorious use. The occupation has to be obvious enough that a reasonable owner paying attention would notice. Hidden use does not count.
- Exclusive control. The occupant holds the land for themselves, not shared with the true owner or the public.
- Hostile possession. “Hostile” has nothing to do with aggression. It means the person is there without the owner’s permission. The moment the owner grants permission, the hostility disappears and the clock stops.
- Continuous and uninterrupted use. Daily presence is not required, but any meaningful abandonment resets the 20-year period.
The New Hampshire Supreme Court summed it up in Blagbrough Family Realty Trust v. A & T Forest Products, Inc. (2007), requiring “twenty years of adverse, continuous, and uninterrupted use of the land claimed so as to give notice to the owner that an adverse claim is being made.”2New Hampshire Law Library.

New Hampshire does not require the occupant to pay property taxes on the disputed land. A record of tax payments is strong evidence that the claimant treated the property as their own, but paying taxes alone does not establish a claim, and failing to pay them does not automatically defeat one.
When the Clock Pauses or Extends
Under RSA 508:3, if the person entitled to recover the land was a minor or mentally incompetent when the adverse possession began, they get an extra five years after that disability ends to sue.3New Hampshire General Court. New Hampshire Revised Statutes Section 508:3 – Disabilities The disability has to exist when the right to recover first arises. An owner who becomes incapacitated years into an adverse occupation does not get the extra time.
In the other direction, successive occupants can combine their time through a doctrine called tacking. The New Hampshire Supreme Court endorsed it in Fagan v. Grady (1957), ruling that continuous adverse use beyond 20 years supports a claim “regardless of any change in the identity of the true owner.”2New Hampshire Law Library. Read The Law About Adverse Possession Tacking requires privity between the occupants, meaning some real connection such as a sale, inheritance, or other transfer of the possessory interest. Two strangers who happen to occupy the same land at different times cannot combine their periods.
What Squatters Cannot Claim
Adverse possession in New Hampshire applies only to private property. You cannot acquire title to public lands, waters, highways, or utility transmission lines through occupation, no matter how long you have been there.4New Hampshire Law Library. New Hampshire Law Library – Adverse Possession Town-owned lots, schoolhouse lots, church lots, and property held under the public trust doctrine are also protected.
Removing a Squatter from Your Property
New Hampshire forbids self-help eviction. An owner who changes the locks, removes the occupant’s belongings, or shuts off utilities can be held liable for actual damages plus a $1,000 penalty for each violation under RSA 540-A.5New Hampshire Judicial Branch. New Hampshire Circuit Court Landlord and Tenant Information Sheet That is true even when the occupant has no lease and never paid rent.
You can report a squatter to law enforcement for criminal trespass under RSA 635:2, which makes it an offense to knowingly enter or remain on property without permission.6New Hampshire General Court. New Hampshire Revised Statutes Section 635:2 – Criminal Trespass A criminal charge does not settle the property dispute or physically remove the occupant. For that, the civil eviction process is the only lawful path.
Step 1: Written Notice to Quit
Deliver a written notice to quit stating the specific reason for eviction. Under RSA 540:3, the notice period for residential property is 30 days in most situations. If the occupant has caused substantial damage or their behavior threatens the health or safety of others, the notice period drops to seven days.7Justia Law. New Hampshire Revised Statutes Section 540:3 – Eviction Notice
Step 2: File a Landlord and Tenant Writ
If the squatter stays after the notice period expires, file for a Landlord and Tenant Writ in the circuit court.5New Hampshire Judicial Branch. New Hampshire Circuit Court Landlord and Tenant Information Sheet New Hampshire uses this terminology rather than summary process. The court schedules a hearing where both sides present evidence. Filing fees apply, and attorney costs are possible.
Step 3: Writ of Possession and the Sheriff
If the court rules in your favor, it issues a Writ of Possession authorizing the county sheriff to physically remove the squatter and change the locks.5New Hampshire Judicial Branch. New Hampshire Circuit Court Landlord and Tenant Information Sheet Local police generally do not handle this step. The sheriff’s office may charge a service fee.
How a Squatter Turns Possession Into Ownership
Satisfying the elements for 20 years does not make the occupant the owner on paper. They have to prove it in court through a quiet title action, a lawsuit filed against the record owner asking the court to decide who actually owns the property.
The claimant carries the burden of proving every element of adverse possession by a preponderance of the evidence. Courts review testimony, physical evidence of improvements and maintenance, photographs, tax records, and witness statements covering the full 20 years. If the claim is proven, the court issues a judgment declaring the adverse possessor the new owner and extinguishing the former owner’s title. That judgment is then recorded at the county registry of deeds, creating a clean chain of title in the new owner’s name.
How Owners Prevent a Claim From Ever Ripening
The 20-year clock only runs when the owner lets it. A few habits keep it from ever reaching the finish line.
- Inspect regularly. Walk the property or hire someone to do so at least once a year. Catching unauthorized use early means the clock never gets far.
- Post and fence the property. Fencing and “No Trespassing” signs create “secured premises” under RSA 635:2, making any entry a criminal misdemeanor and strengthening your position in any later dispute.6New Hampshire General Court. New Hampshire Revised Statutes Section 635:2 – Criminal Trespass
- Grant written permission. If someone is using part of your land and you don’t mind, put it in writing as a revocable license. Permission destroys the hostility element. A short letter stating that you grant permission to use a described area until you revoke it is enough.
- Act quickly on encroachments. If a neighbor’s fence creeps onto your land or someone starts storing equipment on your lot, address it immediately. In O’Malley v. Little (2017), the New Hampshire Supreme Court held that ousting an adverse possessor requires conduct that would put a reasonable person on notice they have been removed. Phone calls and emails are not enough.2New Hampshire Law Library. Read The Law About Adverse Possession
- Stay current on property taxes. Clean tax records make it harder for a claimant to argue they treated the land as their own.
Most New Hampshire adverse possession disputes involve boundary strips, not whole-parcel takeovers. A neighbor builds a shed two feet over the line, maintains that strip for 20 years, and the strip changes hands. A current survey and prompt action on any encroachment prevent those quiet losses more reliably than any remedy available once the 20 years have run.
