A child slips onto a vacant lot, an unfenced pool, a construction site, or the roof of an abandoned building, and is gravely hurt or killed exploring a place that drew them in. When the family asks about a claim, the property owner and their insurer have a ready answer: the child was trespassing, they had no business being there, so the owner owes nothing. It sounds firm, and many grieving families accept it, believing that because their child was somewhere they should not have been, the law offers no recourse.
That belief is wrong, and dangerously so. Massachusetts, like most states, does not treat a child the way it treats an adult trespasser. A child trespasser injury is judged under a special standard that recognizes what every parent knows: children are drawn to dangerous things, cannot appreciate risks that are obvious to adults, and cannot be expected to respect a property line. A landowner who leaves a hazardous condition where children predictably go can be held responsible when a child is hurt by it, trespass or no trespass.
Understanding this child-entrant standard is what separates a family wrongly turned away from one that holds a careless landowner accountable. What follows is how Massachusetts law actually works when a child is injured on someone else’s property — the special duty owed to foreseeable children, where these injuries happen, and why a “keep out” sign is rarely the end of the story. This is general information rather than advice about a specific case, which depends on its own facts.
When “the child was trespassing” is not a defense
The trespass label carries some weight against an adult, but against a child it is far weaker, and understanding why is the starting point.
The instinct to blame the child
The reflexive defense in these cases is to point at the child’s presence: the child was not supposed to be there, so whatever happened is not the owner’s responsibility. It is an emotionally effective argument because it sounds like personal responsibility, and it works on families who assume that trespassing forfeits any claim. But applying that adult logic to a child ignores everything the law understands about how children behave. A young child cannot weigh risks, read warnings, or resist an obvious attraction the way an adult can, and the law does not pretend otherwise. Blaming a child for being a child is exactly the move the child-entrant standard was created to answer, and a child trespasser injury is judged by what the owner should have foreseen and prevented, not by the child’s failure to respect a boundary.
Why children are treated differently
The law treats child entrants differently because children are different. They are curious, impulsive, and drawn to precisely the things that are most dangerous — water, heights, machinery, abandoned structures — and they lack the judgment to recognize or avoid the risks. Holding a small child to an adult’s understanding of danger and property rights would be both unrealistic and unjust. So instead of asking simply whether the child had permission, Massachusetts law asks whether the landowner should have foreseen that children would be drawn to a dangerous condition and failed to protect them. That shift in the question is what makes a child’s case fundamentally different from an adult’s. The law meets children where they are, not where an adult would be.
The Massachusetts child-entrant standard
Massachusetts has codified a specific standard of care owed to trespassing children, drawn from the widely adopted rule for artificial dangers on land. It imposes a duty on a landowner to protect foreseeable child trespassers from certain dangerous conditions — a duty that has no equivalent for adult trespassers. This is not a vague notion of sympathy for injured children; it is a defined legal standard with specific elements, and when those elements are met, a landowner is liable despite the child’s trespass. Knowing that this standard exists, and that it displaces the ordinary trespass rule for children, is what a family needs before accepting a landowner’s claim that nothing can be done. The standard exists precisely so an owner cannot hide behind a boundary a child could never understand.
The duty owed to trespassing children
The child-entrant standard is not open-ended; it turns on a specific set of conditions that, together, define when a landowner is responsible.
A foreseeable place where children trespass
Under Massachusetts General Laws chapter 231, section 85Q, a landowner who maintains an artificial condition on the land can be liable for harm to trespassing children where, among other elements, the owner knows or has reason to know that children are likely to trespass at that place. The foreseeability of children coming onto the land is the threshold. A vacant lot in a neighborhood full of kids, an unfenced pool near where children play, a construction site beside a school route — these are places where a reasonable owner should expect children, and that expectation is what triggers the heightened duty. Where children were foreseeably going to be, the owner cannot treat their presence as a surprise; a place children were always going to reach is not a place the owner gets to be surprised about.
A dangerous artificial condition
The standard applies to an artificial condition — something the owner created or maintains — that the owner knows or should know involves an unreasonable risk of death or serious bodily harm to children. This is the dangerous attraction at the center of these cases: the pool, the machinery, the excavation, the unstable structure. The condition must be one a reasonable owner would recognize as gravely dangerous to a child who encountered it. It is the combination of a serious, owner-created hazard and the foreseeable presence of children that the law is concerned with, because that combination is what predictably leads to a child’s catastrophic injury. The hazard and the children are both foreseeable; only the owner’s inaction is a choice.
Children who cannot appreciate the risk
A central element is that the children, because of their youth, do not discover the condition or realize the risk involved in encountering it. This is the heart of why children are treated differently: the standard protects the child who is too young to understand the danger that an adult would recognize and avoid. A hazard that is open and obvious to an adult may be an irresistible and unappreciated danger to a young child, and the law accounts for that gap in understanding. Where a child was too young to grasp the risk, the fact that the danger might have been obvious to a grown-up does not defeat the claim. To a small child, the deadliest hazards can look like the best places to play.
The balance and the duty to act
Two further elements complete the standard, and together they ask whether the owner reasonably should have removed the danger.
Slight burden versus grave risk
The standard weighs the utility to the owner of maintaining the condition and the burden of eliminating the danger against the risk to children. Where the burden of making a hazard safe — fencing a pool, securing a site, removing an attractive danger — is slight compared to the grave risk it poses to children, the balance tips decisively toward requiring the owner to act. Much of the time, the fix is cheap and simple relative to a child’s life or serious injury, and that imbalance is exactly what the law expects a reasonable owner to recognize. A trivial cost to prevent a catastrophe is a cost the owner is expected to bear; a fence is cheap and a child’s life is not, and the law does that math the same way a careful owner would.
The failure to exercise reasonable care
The final element is that the owner failed to exercise reasonable care to eliminate the danger or otherwise protect the children. This is the breach: having a foreseeable, gravely dangerous condition that children cannot appreciate, and doing nothing reasonable to guard against the harm. An owner who could have fenced, secured, drained, locked, or removed a hazard cheaply and simply, and chose not to, has failed this standard. The duty is not to make the property perfectly childproof but to take the reasonable steps that the obvious risk and the slight burden called for, and the failure to take them is what makes the owner liable. Doing nothing cheap and simple in the face of a grave, foreseeable risk is the definition of the breach.
What reasonable care looks like
Reasonable care under this standard is usually modest and practical: a fence around a pool or an excavation, a locked gate or secured entrance, removal or immobilization of dangerous equipment, boarding up an abandoned building, or otherwise cutting off a child’s access to the hazard. What the law asks is not perfection but the sensible precautions a responsible owner would take knowing children were likely to come and unable to protect themselves. When an owner skips those basic steps in a place children predictably reach, and a child is hurt by the very danger the precautions would have addressed, the standard is met and the trespass label falls away. The measure is what a responsible owner would have done, not what the child should have known.
Where children get hurt
Certain settings recur in these cases because they combine an irresistible draw for children with a grave, owner-created danger.
Vacant lots and abandoned buildings
Vacant lots and abandoned or unsecured buildings are magnets for children and frequent sites of serious injury. Open excavations, debris, unstable floors and stairs, exposed hazards, and the buildings themselves invite exploration while concealing dangers a child cannot foresee. An owner who lets a vacant property sit unsecured in an area where children live and play has created exactly the foreseeable, dangerous situation the child-entrant standard addresses. When a child is hurt exploring such a place, the question is whether the owner reasonably secured it, not simply whether the child had permission to be there. An unsecured vacant property in a neighborhood of children is an accident waiting for a victim.
Construction sites and equipment
Construction sites draw children with heavy equipment, ladders, scaffolding, trenches, and materials that are fascinating and deadly. These sites are often near homes and schools, and the machinery and hazards they contain pose grave risks to a child who wanders in. A site left unfenced, unlocked, or with equipment unsecured after hours is a foreseeable danger, and the contractors and owners responsible for it can be liable when a child is hurt. The obligation to secure a construction site against foreseeable child entry is a recognized part of running one safely, precisely because the risks to a curious child are so severe. Securing a site at the end of the day is routine, and skipping it is a foreseeable danger, not an act of God.
Pools, water, and rooftops
Water and heights are among the most lethal attractions for children. An unfenced or inadequately secured swimming pool is a classic and tragically common example of an attractive, deadly hazard, and the law and building requirements treat pool enclosure as a basic safety obligation. Rooftops, retaining walls, and other heights draw children to climb, with catastrophic consequences from a fall. In each, the combination of a powerful draw, a grave danger, and a child unable to appreciate the risk is exactly what the child-entrant standard was built for, and an owner who failed to secure such a hazard bears responsibility for the predictable result. Water and heights are where these cases turn most tragic and most preventable.
The duty to fence or secure known attractions
The most contested issue in these cases is often whether the owner did enough to keep children away, and here the standard is demanding.
“We posted keep out” — why signs are not enough
Owners frequently defend by pointing to a “no trespassing” or “keep out” sign, as though a posted warning discharges their duty. But a sign that a young child cannot read or will not heed does little to protect a child who cannot appreciate the danger in the first place. The whole premise of the child-entrant standard is that children do not respond to warnings the way adults do, so a sign is rarely a substitute for actually securing a hazard. An owner who relies on a “keep out” sign to guard a pool or an open excavation from young children has usually not taken the reasonable care the situation demanded. A warning a child cannot read is protection in name only.
Securing an attractive hazard
What the standard generally calls for is physical protection — cutting off the child’s access to the danger rather than merely warning against it. Fencing, locking, covering, draining, or removing the hazard are the kinds of measures that actually prevent a child from reaching it. When those steps are inexpensive and simple relative to the risk, as they usually are, an owner who forgoes them in favor of a sign or nothing at all has failed the duty. The question is always whether the owner took the practical, reasonable steps to physically protect foreseeable children, not whether the owner made a gesture toward warning them off. A locked gate stops a child; a sign only informs the adults who were never the ones at risk.
When the owner should have foreseen the child
Foreseeability ties the whole standard together, and it is usually established by the surroundings and history. A hazard in a residential neighborhood, near a school or playground, on a route children use, or on a property where children have been seen or have entered before, is one where a child’s presence is foreseeable. Prior instances of children coming onto the land, a worn path, or the simple reality of the setting all show the owner should have expected them. Where a child’s presence was foreseeable and the hazard grave, the owner’s failure to secure it is what the law holds against them, regardless of the trespass. Foreseeability is written into the ground itself, in the paths and patterns of where children go.
Injuries, parties, and recovery
These cases involve some of the most catastrophic injuries there are, to the most vulnerable victims, and often reach more than one responsible party.
The injuries these cases involve
The injuries to children in these settings are frequently devastating: drownings and near-drownings with lasting brain injury from oxygen loss, falls from height causing spinal and head trauma, crushing injuries from equipment, and burns. Many are catastrophic and permanent, altering a child’s entire life, and the worst are fatal, leaving a family to pursue a wrongful death claim. Because childhood injuries of this severity carry lifelong consequences, and because they are so often preventable with a simple fence or lock, it is especially important that a family not be wrongly turned away by a trespass defense the law does not honor for children. The tragedy is compounded when a preventable death is met with a defense the law never allowed.
Who is responsible
Responsibility can extend to more than one party. The property owner is the primary defendant, but a contractor responsible for securing a construction site, a manager charged with maintaining a property, a municipality or business that let a hazard persist, or the maker of a dangerous piece of equipment may share responsibility. Because these cases echo the broader questions of when a landowner owes a duty to an entrant, they build on the same premises-liability principles that govern an adult trespasser injury claim, with the crucial difference that a child is owed the heightened, protective standard. Identifying every responsible party is central to a full recovery; the owner is the obvious defendant, but the party who was supposed to secure the site may be just as responsible and better insured.
What a family can recover
A seriously injured child, through a parent or guardian, can generally recover for the full extent of the harm: medical and future-care costs, the lasting effects of a permanent injury on the child’s life and future, and compensation for pain and suffering; where a child has died, the family may pursue the losses recognized in a wrongful death claim. Because the injured person is a child, the law provides special protections — a parent brings the claim, the filing deadline is generally paused during childhood, and any settlement is typically subject to court approval to safeguard the child. The purpose is to place the cost of a preventable tragedy on the owner who allowed it, not on the child it harmed. No recovery restores a child, but a full one holds the careless owner to account.
Protecting a child trespasser injury claim
Because these cases turn on foreseeability and the condition of the property, and because owners move quickly to secure a site after a tragedy, early action matters.
Do not accept “trespassing” as the answer
The single most important thing a family can do is refuse to accept the owner’s claim that the child’s trespass ends the matter. Massachusetts law owes a real, protective duty to foreseeable child entrants, and the flat assertion that a trespassing child has no claim is simply not how the law treats children. Getting accurate information — from someone who knows the child-entrant standard rather than from the owner or insurer hoping the family gives up — is what turns a wrongful brush-off back into the claim it actually is. The trespass label is a starting point to be tested, not a verdict, and for a child that label is weaker than for anyone else the law protects.
Document the condition and the foreseeability
Because the case depends on the hazard and on whether children were foreseeable, preserving evidence quickly is essential. Photograph the condition — the pool, the equipment, the open structure — and whatever access or lack of security allowed the child in, before the owner fences or fixes it in response to the injury. Gather evidence that children were foreseeable: the surrounding neighborhood, prior instances of children on the property, worn paths, and the accounts of neighbors. This proof of the dangerous condition and the foreseeability of a child’s presence is exactly what the owner will move to obscure, and capturing it early — before the fix that follows a tragedy erases it — is often decisive.

Frequently asked questions
My child was hurt trespassing on someone’s property. Do we have a claim?
Possibly, and more often than families are led to believe. Massachusetts does not treat a child the way it treats an adult trespasser. A special standard can hold a landowner responsible for a dangerous artificial condition, like a pool, machinery, or an unsecured structure, where the owner should have foreseen that children would come, the children were too young to appreciate the danger, and the owner failed to take the simple, reasonable steps to protect them. So the fact that your child was technically trespassing does not automatically end the claim; the real question is whether the owner met the duty the law owes to foreseeable children.
The owner says the child should not have been there. Does that end it?
No. That argument applies adult logic to a child, which is exactly what the law rejects. Young children cannot appreciate risks, read or heed warnings, or respect property lines the way adults can, and Massachusetts law accounts for that. If the owner maintained a dangerous condition where children were likely to go and failed to take reasonable steps to secure it, the child’s trespass does not excuse the owner. The owner’s insistence that the child had no business being there is a starting point to be tested against the child-entrant standard, not a conclusion.
Isn’t a “no trespassing” sign enough to protect the owner?
Usually not, when the danger is to young children. The whole premise of the child-entrant standard is that children do not respond to warnings the way adults do, and a sign a young child cannot read or will not heed does little to protect them. The law generally expects an owner to physically secure a serious hazard, by fencing, locking, covering, or removing it, when doing so is simple relative to the grave risk to children. Relying on a “keep out” sign to guard something like an unfenced pool from young children is rarely the reasonable care the situation required.
What kinds of hazards does this cover?
It covers dangerous artificial conditions, things the owner created or maintains, that pose a grave risk to children who cannot appreciate the danger. Common examples include unfenced swimming pools, construction sites and heavy equipment, open excavations and trenches, abandoned or unsecured buildings, rooftops and heights, and similar hazards that predictably attract children. The key is the combination of a serious, owner-created danger, a place where children are foreseeable, and a child too young to understand the risk. Natural conditions and dangers a child of that age would readily understand are treated differently.
What should I do after my child is hurt on someone’s property?
Get your child medical care first, and keep the records. Then, if you can, photograph the hazard and the property, especially the condition that hurt your child and how they were able to reach it, before the owner secures or repairs it. Gather evidence that children were foreseeable there, the neighborhood, prior instances of children on the property, and neighbors’ accounts. Preserve anything showing what the owner knew. Then get legal advice promptly, because the evidence changes fast once an owner reacts to the injury, and a child’s claim involves specific protections and procedures worth handling correctly from the start.
