A storm rolls through, a heavy limb or a whole tree comes down, and it lands on a parked car, a sidewalk, a passing vehicle, or a person. When the dust settles and someone asks who is responsible, the answer comes back almost automatically: it was the storm, an act of God, nobody’s fault, nothing anyone could have done. And with that, a lot of people who were seriously hurt or whose property was destroyed simply absorb the loss, assuming the weather is to blame and no claim exists.
Sometimes the storm really is the whole story. But very often it is not, because the tree that came down was not a healthy tree felled by an extraordinary wind; it was a dead, diseased, or obviously hazardous tree that someone — a town, a tree warden, or a private owner — knew about or should have known about and left standing. A falling tree injury in Massachusetts is not automatically excused by the fact that a storm was the final push. The real question is whether the tree was a known hazard that reasonable care would have addressed.
Understanding that distinction is what separates an unavoidable act of nature from a preventable failure someone can be held responsible for. What follows is how these cases actually work in Massachusetts — when a public tree becomes a town’s responsibility, when a private owner is liable for a dead tree, and why the whole thing usually turns on the question of notice. This is general information rather than advice about a specific incident.
When a falling tree is someone’s fault, not just bad luck
The instinct to blame the weather is exactly what a responsible party hopes you will do, so it helps to see where the “act of God” line stops.
The “act of God” defense and its limit
An act-of-God defense argues that an extraordinary, unforeseeable natural event caused the harm and no human negligence contributed to it. It is a real defense, but it is far narrower than the way it gets thrown around. A storm does not transform a hazard that already existed into an unavoidable accident. If a tree was already dead, decayed, or dangerously compromised, and a foreseeable wind simply finished what neglect had started, the storm is not the whole cause, and the party who ignored the hazard does not get to hide behind the weather. The defense works only when the event was truly the sole cause; it fails when a pre-existing, known danger was waiting for any strong gust to bring it down. In that situation a falling tree injury is a preventable harm dressed up as an accident of nature.
The key question: was the tree a known hazard?
Nearly every falling-tree case comes down to a single question: was this tree a known or knowable hazard before it fell? A visibly dead tree, a trunk riddled with rot, a large dead limb hanging over a sidewalk, a tree that had been the subject of complaints — these are hazards that reasonable inspection and care would catch and address. When the responsible party knew or should have known the tree was dangerous and did nothing, the resulting harm is not bad luck; it is negligence. The storm becomes merely the occasion, not the cause. Establishing that the danger was apparent and ignored is the heart of holding someone responsible, and it is usually proven from the tree’s own condition rather than from the weather report.
A healthy tree in a storm versus a dead tree waiting to fall
The law sensibly distinguishes between the two very different scenarios that both end with a tree on the ground. A sound, healthy tree brought down by a genuinely severe and unusual storm may indeed be nobody’s fault — an act of nature no reasonable care would have prevented. A dead or visibly failing tree that comes down in an ordinary wind is a different matter entirely, because the danger was there all along and the storm only exposed it. Most contested cases live in that second category, where the defense wants to call it a storm and the facts show a hazard that had been ignored for months or years. Telling those two situations apart is what these cases are really about, and it is a question an arborist can usually answer.
Public shade trees and the tree warden
When the tree that fell was on public land or along a public way, a specific municipal framework governs who was responsible for it.
The tree warden’s control over public trees
Massachusetts places public shade trees under the authority of a municipal tree warden. Under Massachusetts General Laws chapter 87, section 3, public shade trees generally cannot be cut, trimmed, or removed except by the tree warden or with the tree warden’s written permission and, in many cases, after a public hearing. That control comes with responsibility: the entity that has authority over the public trees is the entity expected to monitor and maintain them in a reasonably safe condition. When a hazardous public tree injures someone, the tree warden’s role and the town’s duty to manage its own trees are central to the claim, because control over the tree carries the obligation to keep it from becoming a danger to the public.
When a town is liable for a hazardous public tree
A city or town can be held responsible when it fails to maintain a public tree it knew or should have known was dangerous, much as it can be for any negligently maintained public property. The reflexive claim that a municipality is simply immune is, as with other public-entity claims, overstated — a subject our discussion of governmental immunity explains in detail. The negligent maintenance of public property, including a hazardous tree the town had notice of, is generally not shielded. The town’s liability turns on the same question as any tree case — whether it had reasonable notice of the hazard — layered on top of the special procedures and limits that apply to claims against public entities. The weather may have been the trigger, but the town’s failure to deal with a tree it knew was failing is what the law examines.
Trees on a public way and the defective-way rule
When a tree or limb hazard is connected to a public way, a distinct statute can come into play. Under chapter 84, section 15, a person injured by a defect in a public way may recover from the city, town, or party obliged to maintain it, but only if that entity had, or by reasonable care should have had, notice of the defect, and this remedy carries a notably low statutory cap and its own short notice requirement. Whether a particular tree hazard is treated as a way defect under this statute or as negligent maintenance of public property can matter a great deal, because the route the claim takes affects the deadline, the notice rules, and the limit on recovery. Sorting out which framework applies is an important early step in a public-tree case.
The notice question that decides these cases
Across every version of these claims, public or private, one issue recurs and usually controls the outcome: notice.
What “notice” means
Notice is the legal way of asking whether the responsible party knew, or should have known, that the tree was dangerous. It comes in two forms. Actual notice means someone actually knew — a prior complaint about the tree, a warning from a neighbor, an inspection that flagged it, a work order that was never completed. Constructive notice means the danger was so apparent that reasonable care would have discovered it — a tree that was obviously dead, visibly rotted, or leaning badly for a long time. Either form can establish responsibility. The presence of prior complaints on file with a town, or the plain visibility of decay, is exactly the kind of evidence that turns a “nobody could have known” defense into a losing one.
Storm damage versus pre-existing decay
The battleground in most of these cases is whether the tree failed because of the storm or because of a condition that existed long before it. A sound tree and a rotten one can both end up on the ground after the same wind, but they tell very different legal stories. Evidence of the tree’s actual condition — the decay in the trunk, the deadwood, the fungus, the hollowing — often reveals that the failure was waiting to happen and the storm was incidental. This is why the physical remains of the tree, and any records of its history, matter so much: they can show that what looks at first like storm damage was really the collapse of a hazard that should have been dealt with long before. A qualified arborist examining the stump can often read that history as plainly as rings on a cut log.
Proving the hazard was known or knowable
Building a falling-tree case means assembling the proof that the danger was there to be seen. Prior complaints or service requests to the town or owner, photographs showing the tree’s condition before or after, the observations of neighbors and passersby, maintenance and inspection records, and expert examination of the fallen tree’s condition all combine to establish notice. A responsible party will insist the failure was sudden and unforeseeable; the evidence of long-standing decay and prior warnings is what answers that. Because much of this proof can disappear quickly once the tree is cleared away, gathering it early is often what makes the difference between a provable claim and a he-said-she-said about the weather.
Private landowners and dead trees
When the tree that fell stood on private land, a different but related set of duties governs whether the owner is responsible.
A landowner’s duty for a defective tree
A private property owner is expected to exercise reasonable care regarding the trees on their land, particularly trees that could harm people or property beyond the owner’s own boundaries. An owner who knows, or by reasonable attention would know, that a tree is dead, diseased, or structurally dangerous has a responsibility to address it before it falls on a neighbor, a pedestrian, or the road. This duty is strongest where people and property are foreseeably in harm’s way — along sidewalks and streets and near neighboring homes — and where the danger is one a reasonable owner would have noticed. When an owner ignores an obviously hazardous tree and it causes the harm that was foreseeable, the owner can be held responsible for the result. The more foreseeable the harm and the more obvious the decay, the harder it is for the owner to claim surprise.
The natural-condition rule and its exception
Older law was reluctant to hold a landowner responsible for a purely natural condition of the land, including a tree, on the theory that the owner did not create it. But that rule has given way, especially in developed and populated areas, to the recognition that an owner who knows of a dangerous tree cannot simply ignore it. The modern approach focuses on the owner’s knowledge and the foreseeability of harm: a dead tree looming over a busy sidewalk is not the same as a remote tree deep in the woods, and an owner aware of the danger is expected to act. The defense that a tree is just a natural condition no one is responsible for is far weaker when the owner knew the tree was a hazard to others.
Trees falling onto a neighbor or the road
A great many private-tree cases involve a hazardous tree that falls across a property line or into the street. When an owner’s known-dangerous tree damages a neighbor’s home or car or injures someone next door, the neighbor’s recourse runs against the owner who let the hazard stand, a dispute that turns on the same principles of neighbor and property-owner liability. When the tree falls into a public road and causes a crash or a pedestrian injury, both the private owner and, depending on the circumstances, the responsible public entity may be in the picture. Identifying whose tree it was and who had notice of its condition is the starting point for sorting out responsibility.
The short deadlines and special rules
Falling-tree claims carry deadline and procedural traps that vary sharply depending on who is responsible, and missing them can end a valid claim.
The notice and presentment rules for public claims
A claim against a city or town for a public tree is subject to the special procedural requirements that apply to public entities, including a written presentment of the claim within a strict deadline, and, where the defective-way statute applies, an even shorter notice requirement measured in weeks. These steps are prerequisites, not formalities, and a claim can be lost entirely if they are missed. Because a falling-tree injury involving a public tree may implicate more than one of these frameworks, the safest course is to treat any claim touching a town’s tree as time-sensitive from the very first day and get the required notices prepared and delivered correctly and early, before a strict clock quietly runs out.
The low cap on way-defect claims
Where a claim proceeds under the defective-way statute, the recovery from the public entity is subject to a notably low statutory cap. That limit is a reason to understand exactly which framework a claim falls under and to identify every other responsible party, because a private owner or a tree-service company whose negligence contributed is not subject to that cap. As with other public-entity claims, a case that looks small against a capped municipality can be far more substantial once the uncapped private parties are brought in. The cap limits one defendant, not the whole case.
The ordinary deadline for private claims
A claim against a private landowner is generally governed by the ordinary personal-injury deadline rather than the special public-entity rules, which usually allows more time than a claim against a town. But that additional time is not a reason to wait, because the single most important piece of evidence — the condition of the tree itself — disappears as soon as the fallen tree is cut up and hauled away. Whatever the applicable deadline, the practical clock on preserving proof of the tree’s condition and the history of notice runs out almost immediately, which makes prompt action essential regardless of who is responsible. A tree that is cleared within a day of falling can take the best evidence in the case with it.
Injuries and who is responsible
Falling trees and limbs cause some of the most severe injuries there are, and these cases often involve more than one responsible party.
The injuries falling trees cause
A falling tree or heavy limb strikes with enormous force, and the injuries reflect it: crushing injuries, fractures, spinal damage, and severe head trauma, including traumatic brain injuries when a limb strikes a person’s head. A tree falling on an occupied car or a pedestrian can be catastrophic, and in the worst cases it is fatal, leaving a family to pursue a wrongful death claim. Even where the immediate impact is survivable, the consequences can be lasting and life-altering. The gravity of these injuries is part of why it matters so much that a preventable hazard not be written off as an unavoidable act of the weather.
Multiple responsible parties
These cases frequently involve more than one party who could be responsible. A public tree may implicate the town and its tree warden; a private tree, the landowner; and in either case a tree-service company that inspected or negligently worked on the tree, or a property manager responsible for the grounds, may share the blame. Sorting out who owned the tree, who controlled it, and who had notice of its condition is what identifies the full set of responsible parties. Because some of them — the private ones — are not subject to the municipal caps, finding every party who bears responsibility is central to valuing and building the claim.
What a victim can recover
A person injured by a negligently maintained tree can generally recover for the full extent of the harm: medical expenses, lost income and lost earning capacity, and compensation for pain, suffering, and the disruption to their life, along with property damage where a vehicle or home was destroyed. Where the injury is permanent or a death has occurred, the losses recognized are correspondingly greater. The purpose is to place the cost of a preventable hazard on the party who failed to address it rather than on the innocent person it struck, and a properly built claim seeks the true measure of that harm rather than the nothing that an “act of God” framing offers. For a serious or permanent injury, that difference is enormous, and it should not be conceded to a convenient story about the weather.
Protecting a falling tree injury claim
Because the key evidence vanishes fast and the deadlines can be short, what a person does immediately after a tree comes down often decides whether a claim can be proven.
Document the tree and the scene immediately
Photograph everything before the tree is cleared: the fallen tree and especially the condition of the trunk and the break, any visible rot, decay, deadwood, or disease, the location, and the damage. If it can be done safely and legally, preserving a section of the trunk showing its internal condition can be invaluable, because that internal decay is often the clearest proof that the failure was waiting to happen. Note exactly where the tree stood — on public land, along a way, or on private property — since that determines who is responsible and which rules apply. This documentation is the evidence that answers the storm defense, and it is available only in the short window before cleanup.
Preserve evidence of prior notice
Because notice usually decides these cases, gather anything showing the hazard was known. Prior complaints or service requests about the tree, communications with the town or the owner, neighbors’ accounts of how long the tree had looked dead or dangerous, and any records of past work on it all help establish that the danger was known or should have been. Neighbors are often the best source of the history a responsible party would rather forget. Capturing these accounts while memories are fresh, and requesting any records a town or owner holds, builds the notice case that turns a suspected hazard into a proven one.
When to bring in a Boston injury lawyer
These cases combine a disappearing piece of key evidence, a notice question that decides liability, and, where a public tree is involved, strict deadlines and caps that are easy to miss — a great deal to manage alone after a serious injury. A lawyer moves quickly to preserve the tree evidence and the history of notice, determines which framework and deadlines apply, identifies every responsible party including uncapped private ones, and answers the act-of-God defense that so often follows a falling tree injury with proof of a known hazard; these cases are handled on contingency, so there is no fee unless there is a recovery. Our Boston personal injury attorneys handle tree and premises injury claims across the Commonwealth, including claims against public entities like those discussed in our coverage of a dangerous public way and government liability, work reflected across our practice areas and in nearby communities including Quincy and Cambridge. If a tree or limb hurt you or destroyed your property and you were told it was just the storm, a first conversation costs nothing, and you can reach out before the evidence is cleared away.

Frequently asked questions
Is anyone liable if a tree falls on my car or me?
Possibly, and often yes. The key question is whether the tree was a known or knowable hazard before it fell. If it was dead, decayed, or obviously dangerous and the responsible party, a town, a tree warden, or a private owner, knew or should have known and failed to address it, that party can be liable even though a storm delivered the final push. A genuinely healthy tree brought down by an extraordinary storm may be nobody’s fault, but a hazard that had been ignored for months is a different matter. Being told it was simply the storm is not the end of the inquiry.
The town says it was a storm, an act of God. Is that a defense?
Not automatically. An act-of-God defense only works when a truly extraordinary natural event was the sole cause and no negligence contributed. It does not excuse a pre-existing hazard. If the tree was already dead or dangerously decayed and an ordinary wind brought it down, the storm was the occasion, not the cause, and the party who ignored the known danger can still be responsible. The defense is far narrower than the way it is used, and it fails where the evidence shows a hazard that reasonable care would have addressed before any storm arrived.
My neighbor’s dead tree fell on my property. Who is responsible?
If your neighbor knew, or by reasonable attention should have known, that the tree was dead or dangerous and did nothing, the neighbor can be responsible for the resulting damage or injury. Massachusetts increasingly expects landowners to address trees they know are hazardous, especially where the danger to neighbors, sidewalks, and streets is foreseeable. The old idea that a tree is just a natural condition no one is responsible for is much weaker when the owner was aware of the hazard. Documenting the tree’s condition and what the owner knew is key to establishing responsibility.
How long do I have to bring a claim, especially against a town?
It depends on who is responsible. A claim against a private owner generally follows the ordinary personal-injury deadline, but a claim involving a public tree is subject to special, strict, and much shorter procedural requirements, including a written presentment and, in some situations, an even shorter notice period measured in weeks. Missing these public-entity steps can end an otherwise valid claim. Because the applicable deadline can be very short and the tree evidence disappears almost immediately, it is important to treat any tree-injury situation as time-sensitive and get advice quickly.
What should I do after a tree or limb injures me?
Get medical care, then document the scene before the tree is cleared: photograph the fallen tree and especially the condition of the trunk and the break, any rot or deadwood, the location, and the damage. Note whether the tree stood on public or private land, since that determines who is responsible. Gather evidence that the hazard was known, such as prior complaints or neighbors’ accounts of how long it had looked dangerous. Then get legal advice promptly, because the key evidence and, for public-tree claims, the deadlines both run out fast.
