Read the Disclaimer, Then the Statute Numbers

This page is general information about New Hampshire law, not legal advice, and it is not a substitute for talking to a New Hampshire attorney about your specific property. Statutes and case law change; the citations here were checked on August 6, 2026. If money, a property line, or a neighbor relationship is at stake, get a survey and get counsel before anyone starts cutting.

That paragraph is not throat-clearing. Search whether you can cut a neighbor's branches here and the top results will tell you, without a citation, that state law gives you the right to trim back to the line. No statute says it. No decision of the state Supreme Court says it.

What does exist, and what almost no local tree page mentions, is a statute that prices a bad guess about a boundary at three to ten times the value of every tree involved.

Branches and Roots That Cross Onto Your Land

Most of the country follows a common-law rule that you may cut back the part of a neighbor's tree reaching onto your land, at your own expense, from your own side. New Hampshire has no statute on it, and its Supreme Court raised the question in 2011 and declined to answer. The limits matter more than the rule.

• The line is the exposure, not the trimming. Anything cut past it falls under RSA 227-J:8, which reaches negligent cutting: a careless guess about the boundary is negligence, not a defense.
• Stepping into the yard is a separate offense. RSA 635:2 makes that criminal trespass, and a class B felony where someone knowingly or recklessly causes damage over $1,500.
• A cut that kills the tree can land on you. No New Hampshire decision says so — treat it as prudence, not law. Roots get the same negligence analysis as limbs.

A Trunk on the Line Belongs to Both of You

New Hampshire case law going back to the 1800s treats a tree whose trunk sits on the boundary as the common property of both neighbors, and neither may cut or destroy it without the other's consent. Nobody owns the half on their side, and paying the whole bill is not permission. If both households agree the tree should go, write it down first — identify the tree, date it, and each keep a signed copy. Where the line is unclear, the survey is the cheap part.

RSA 227-J:8: Three to Ten Times the Value of Every Tree

This is the most expensive mistake available to a New Hampshire homeowner. RSA 227-J:8, I: "No person shall negligently cut, fell, destroy, injure, carry away ... any tree, timber, log, wood, pole, underwood, or bark which is on the land of another person, or aid in such actions without the permission of that person or the person's agent." Paragraph II sets the price — the violator "shall forfeit to the person injured no less than 3 and not more than 10 times the market value of every such tree," and that is "in addition to any other civil or criminal penalty allowed by law." (Text effective January 1, 2022; as of August 2026.)

• The floor is a multiple, not a dollar amount, and negligence is enough — nobody has to intend to take anyone's timber. Nor is this only a logging statute: the text says any tree, so a sixty-year-old maple in a front yard sits inside it.
• It reaches whoever holds the saw — anyone who aids in such actions. No case we found divides liability between a homeowner and the contractor they hired.
• Only the owner can give permission — "that person or the person's agent," so a tenant cannot authorize a cut. Reckless cutting is separately criminal under RSA 227-J:8-a.
• It has teeth. In Berliner v. Clukay, 150 N.H. 80 (2003), a logger who crossed a boundary in Landaff argued the trespass was inadvertent and was held to a $648,500 verdict — $263,500 of it statutory, at a multiplier of 8.5.

A Healthy Tree Comes Down in a Storm

A sound tree that a storm puts across the fence is generally nobody's fault; the New Hampshire standard turns on decay the owner knew or should have known about. What decides the money is the policy. General information, not insurance advice — your policy, your carrier and your adjuster decide.

• Coverage follows where the tree lands, not where it grew. Insurers generally treat a fallen tree as the problem of whoever it landed on, so one that hits your house goes to your own carrier (Insurance Information Institute). If it was dead or failing, your carrier may then pursue the owner's.
• Debris removal is capped, and low. Policygenius, updated May 2024, describes the standard policy as paying "up to $1,000 total for tree removal, but no more than $500 for any one tree," for wind, hail or the weight of ice and snow, and only where the tree lands on an insured structure.
• A tree that hits nothing is usually yours to clear — no structure struck, generally no removal coverage, and none for rot, age, pests or disease.
• The trees are barely covered either. The Insurance Information Institute puts standard coverage for trees, plants and shrubs at "generally for about $500 per item," and "not covered for disease, or if they have been poorly maintained."

The Tree Somebody Was Warned About

The analysis flips once a tree is visibly bad. In Pesaturo v. Kinne, 161 N.H. 550 (2011) — a case that began as a small claims action in Nashua District Court — the New Hampshire Supreme Court held that a landowner who knows or should know a tree is decayed or defective, and fails to maintain it reasonably, is liable for the injuries it causes, including harm off their own property. The duty has a limit: the decay must be readily observable.

• What 'readily observable' looks like. The federal field standard flags a stem where sound wood is thinner than 1 inch for every 6 inches of trunk diameter, a canker wrapping more than half the circumference, or more than half the roots under the crown cut or crushed. (USDA Forest Service, NA-FR-01-96, rev. 2012.)
• A dated letter with photographs moves the question from whether they should have known to the fact that they were told, on a date. It is evidence, not a trigger: no statute requires it.
• Know the ceiling. RSA 503:1 sets New Hampshire small claims at $10,000 for matters not involving title to real estate, with a jury demand available above $1,500 and mandatory mediation above $5,000.

Trees at the Road and Trees Under the Wires

The right-of-way usually extends past the pavement, often into what looks like lawn; the width varies by road and by deed, so pull your plan or call the DPW. Being inside it does not by itself make a tree the town's — under RSA 231:140, municipal control attaches to shade and ornamental trees the town acquired.

• Hazard trees in the highway limits. RSA 231:145 lets a town (or NHDOT on state roads) declare a tree there, alive or dead, a public nuisance for danger to traffic, tree disease, or utility equipment. After notice to the abutter it comes down "without compensation or cost to the abutter" — and no notice is required where delay poses an imminent threat.
• Tree wardens. Removing a public shade tree the city owns goes to the warden under RSA 231:144, after a noticed hearing. The office is optional (RSA 231:139); the Division of Forests and Lands keeps a public roster. We could not confirm whether Nashua has one.
• Fifteen inches of circumference, in two places. Under RSA 231:150 a town clearing a highway may not remove a tree of 15 inches circumference or more at 4 feet up without notice to the abutter, absent imminent danger. On a designated scenic road, RSA 231:158 adds prior written planning board consent.
• The wire at the road is two wires. Eversource clears its distribution lines every four to five years, targeting no limbs within 8 feet to the side, 10 feet below or 15 feet above. Its guidance is that the service line from pole to house is yours to keep clear.
• Never do wire work yourself. OSHA's minimum approach distance for anyone who is not a trained line-clearance tree trimmer is 10 feet from a conductor at 50 kV or below. Eversource will temporarily remove the pole-to-house line so a contractor can work safely.

What Else Ends Up on the Same Work Order

Removal is one line on a longer list: the pruning, the stump, the brush pile, and the back lot nobody has touched in thirty years.
