If someone is trespassing on your property, start with a clear verbal warning to leave, document what happens, and call law enforcement if the person refuses or comes back. Those three steps handle most situations without exposing you to legal risk of your own. The harder questions, like how much force you can use, when you can be sued by the trespasser, and how to stop a repeat problem, have specific answers that are worth knowing before you need them.
Tell the Person to Leave
The first step is also the most legally significant one. Tell the person they’re on private property and ask them to leave. A verbal warning does two things at once: it removes any defense that the person didn’t know they were trespassing, and it sets up a more serious charge if they refuse to go or come back later. In most jurisdictions, someone who remains after being told to leave has committed a more serious offense than someone who merely wandered in.
Stay calm and direct. “This is private property and you need to leave” is enough. Avoid threats, profanity, and physical contact. If you can have another person present as a witness, do that. If the person leaves without incident, write down the date, time, what you said, and what they looked like. That record matters if they come back.
Call the Police if They Refuse or Return
When a trespasser refuses to leave, returns after being warned, or creates any safety concern, call the police. You don’t have to resolve the situation yourself, and trying to can make things worse for you. Officers can assess whether a crime has been committed, remove the person, issue a citation, or make an arrest depending on the circumstances.
Before you call, pull together whatever documentation you have: photos, video, witness names, and your log of any prior incidents. An officer responding to a well-documented complaint is far more likely to take formal action than one responding to a vague report. The police report itself becomes part of your legal record, which matters if you later pursue civil remedies or want criminal charges filed.
Simple trespassing is typically charged as a misdemeanor. Penalties vary by jurisdiction but commonly include fines and the possibility of jail time, with sentences of up to a year for higher-degree misdemeanors like entering an occupied residence or fenced property. The offense can rise to a felony when the trespasser entered with intent to commit another crime, carried a weapon, or caused serious property damage.1Justia. Criminal Trespass Laws
Criminal charges are brought by the state, not by you. Your role is to file a complaint and provide evidence. The prosecutor decides whether to move forward. A conviction doesn’t automatically compensate you for any damage, but it creates a public record that strengthens a later civil case and acts as a deterrent against repeat offenses.
What Force You Can and Can’t Use
This is where property owners get into the most trouble. The instinct to physically confront or remove a trespasser is understandable, and the law draws much narrower lines around it than most people assume.
Non-Deadly Force
Some jurisdictions permit reasonable, non-deadly force to eject a trespasser who refuses to leave after being asked. “Reasonable” is doing most of the work in that sentence. Shoving someone off your porch after they refuse to leave might be defensible. Tackling someone walking across your back field almost certainly is not. The safer course in nearly every case is to call law enforcement rather than make physical contact. If the situation turns violent, your use of force will be scrutinized against what a reasonable person would have done, and juries are skeptical of property owners who escalate.
Deadly Force
Deadly force is never justified solely to remove a trespasser from your land. Castle doctrine laws in many states create a legal presumption that you may use deadly force against someone who forcibly enters your occupied home, but even those laws typically require three things: the intruder must actually be entering the residence, the home must be occupied at the time, and you must reasonably believe the intruder intends violence against the occupants. Walking across your yard, or even entering an unoccupied building on your property, doesn’t meet that threshold.
If a trespasser threatens you with deadly force, you may respond in self-defense, but the legal justification at that point is self-defense, not property protection. The distinction changes what you have to prove.
No Traps or Mechanical Devices
Setting booby traps, spring guns, or other mechanical devices designed to injure trespassers is illegal in virtually every jurisdiction, even on your own property. The leading case is Katko v. Briney, where a landowner rigged a shotgun to fire when someone opened a door in an unoccupied farmhouse. The trespasser who was shot sued and recovered both compensatory and punitive damages. You cannot use deadly force to protect unoccupied property, and a device that does so on your behalf is treated no differently from pulling the trigger yourself.
Document the Incident
If trespassing happens more than once, documentation becomes your most important asset. Record the date, time, location on your property, a physical description of the trespasser, and what they did or said. Photograph or video any damage, disturbed areas, or the trespasser’s presence if you can do so safely. Smartphone timestamps and GPS metadata can corroborate your account later.
If you have No Trespassing signs posted, photograph them in relation to where the person entered or was found. That visual evidence shows a court the person had reasonable notice. Keep a running log if the problem is ongoing. A single incident is an annoyance. A documented pattern is a case.
A Caution About Audio Recording
Recording a trespasser on your own property sounds obvious, but audio recording laws can trip you up. A majority of states follow a one-party consent rule, which lets you record a conversation you’re part of without telling the other person. A smaller group of states requires everyone in the conversation to consent. Violating these rules can itself be a criminal offense, even on your own land. Video-only surveillance without audio is generally less restricted, but the specifics depend on where you live. If you’re installing security cameras that capture sound, check your state’s recording laws first.
Signs, Fences, and Clear Boundaries
Posting signs serves a legal purpose beyond discouraging intruders. In many jurisdictions, a person can only be charged with criminal trespass if they had notice that entry was prohibited. Signs provide that notice automatically, without requiring you to confront every trespasser personally. Some states have detailed requirements for sign size, spacing, and placement; others simply require that notice be given in some written or verbal form. When in doubt, use signs that are clearly legible, placed at regular intervals, and visible at every entry point, including gates, trails, and fence lines.
Fencing reinforces the message. A fence doesn’t need to be impenetrable. Even a basic perimeter fence signals that entry is intentional rather than accidental. Combined with posted signs, fencing makes it much harder for a trespasser to claim they didn’t realize they were on private land.
Boundary disputes are a trespasser’s best friend. If there’s any ambiguity about where your property ends, a trespasser can argue they didn’t know they’d crossed the line, and a court may find that persuasive. A professional boundary survey eliminates the problem. A licensed surveyor maps your property’s exact dimensions and places physical markers at the corners and along the borders. The survey can be filed with your local government and used as evidence in court. If you install a fence or wall to reinforce the surveyed line, make sure it sits on your side; a fence built six inches onto a neighbor’s land creates a new dispute instead of solving the old one.
Why Ignoring a Trespasser Is Risky
Letting someone use your land openly and continuously can eventually cost you the land itself. Adverse possession allows a person to claim legal ownership of property they’ve occupied without permission, provided their possession was hostile, actual, open, exclusive, and continuous for the period set by state law. That period ranges from as few as five years to as many as 20 or more, depending on the jurisdiction and whether the possessor has a claim of title.2Legal Information Institute. Adverse Possession
“Hostile” doesn’t mean aggressive in this context. It means the person is using the land as if it were theirs, without your permission. If you’ve given someone permission to use part of your property, that use can never ripen into adverse possession. Some owners grant written, revocable licenses to neighbors who use shared paths or driveways for exactly this reason. The license proves the use was permissive and blocks any future ownership claim.
Civil Remedies for Repeat Trespassers
Criminal charges punish the trespasser. Civil remedies protect you going forward. The two tracks are independent, and you can pursue both at once.
Injunctions
An injunction is a court order directing the trespasser to stay off your property. This is the most useful civil tool for repeat trespassers because it converts future trespassing from a property dispute into contempt of court, which carries its own penalties including fines and jail time. To get one, you generally need to show the trespassing is ongoing or likely to recur and that money alone won’t fix it. Many courts have standardized forms; the clerk’s office can point you to them.
Monetary Damages
You can sue a trespasser for the financial harm their intrusion caused. Compensatory damages cover measurable losses: the cost to repair damaged fences or landscaping, lost income from land you couldn’t use, and diminished property value. If the trespasser didn’t cause physical damage, you may still be entitled to nominal damages for the violation of your property rights. Some states authorize statutory or multiple damages for certain types of trespass as a deterrent, and especially egregious conduct can support punitive damages on top of actual losses.
Ejectment
When a trespasser has effectively taken up residence or refuses to leave, an ejectment action asks the court to order their removal. This is more common in disputes involving squatters or people who overstay a license to use the property. You’ll need to prove you hold legal title and that the occupant has no right to be there. If the court rules in your favor, local authorities can enforce the removal.
Restraining Orders
If the trespasser’s behavior rises to harassment or threats, you may be able to obtain a civil restraining order, sometimes called a protective order. The process varies by jurisdiction, but it typically involves filing a petition describing the conduct, attending a hearing, and presenting evidence. A restraining order carries more personal weight than a general injunction because violating it can lead to immediate arrest. This is particularly useful when the trespasser is a specific person you can identify, like a neighbor or former tenant.
When You Can Be Liable if a Trespasser Gets Hurt
Here’s the part that surprises many property owners: in certain situations, you can be held liable for injuries a trespasser suffers on your land. The traditional rule still gives you significant protection. You generally owe trespassers no duty of care beyond refraining from intentionally or recklessly injuring them. You don’t have to make your property safe for people who aren’t supposed to be there. The exceptions are what you need to watch for.
Known or Anticipated Trespassers
If you know people regularly cut across a particular part of your land, your duty increases. For known or anticipated trespassers, you must use reasonable care in any activities you conduct on the property, and you may need to warn them about hidden artificial hazards that pose a serious risk of death or injury, especially where the trespasser wouldn’t notice the danger on their own. A concealed excavation near a path you know people use, for example, might call for a warning sign or barrier.
Children and Attractive Nuisances
The biggest exception involves children. Under the attractive nuisance doctrine recognized in most states, you can be liable for injuries to child trespassers if your property contains a man-made condition that attracts children, poses a serious risk of harm, and could have been made safer without unreasonable burden. Swimming pools, construction equipment, abandoned vehicles, and unfenced machinery are common examples. Natural features like ponds and trees generally don’t trigger the doctrine. The key factors are whether you knew or should have known children were likely to trespass, whether a child wouldn’t appreciate the danger, and whether you failed to take reasonable precautions.
Recreational Use Statutes
If you own rural or undeveloped land, recreational use statutes may work in your favor. All 50 states have enacted some version of these laws, which shield landowners from liability when they allow the public to use their land for recreational purposes without charging a fee.3National Agricultural Law Center. States’ Recreational Use Statutes The protection typically disappears if you charge for access or if the injury results from your willful or reckless conduct. These statutes were designed to encourage landowners to keep their property open for hiking, hunting, fishing, and similar activities without facing a lawsuit every time someone twists an ankle.
Who Isn’t a Trespasser
Not everyone who enters your property uninvited is trespassing, and confronting them as if they were can create problems for you. Utility workers with easement rights can access portions of your property to maintain infrastructure like power lines, water mains, and sewer systems. These easements are typically recorded in your deed or with local government offices. Law enforcement officers with valid warrants, or officers in hot pursuit, can enter without your permission. Firefighters and paramedics can access your property when responding to an emergency. Government inspectors may have statutory authority to enter in specific regulated contexts, such as building code or environmental compliance.
Knowing what easements are recorded against your property helps you tell legitimate access from actual trespassing. If you’re not sure, your deed and a title search will show what access rights other parties hold.
