Do you owe a duty of care to injured trespassers?

On Behalf of | Jun 3, 2026 | Premises Liability Defense

Someone walks onto your business property without permission, suffers an injury and later names the building as the cause. The situation raises an uncomfortable question for any owner: does an uninvited visitor have a claim against you?

Standards that govern trespasser injuries

Under Oklahoma law, the duty owed to a person who enters without permission is narrow. You are not required to maintain the premises in a safe condition for a trespasser, and you generally bear no liability for an injury that befalls one, provided you do not intentionally or wantonly cause them harm, or set hidden traps.

The courts base this standard in practicality. The law does not expect you to maintain your property for visitors whose presence you have no reason to anticipate, and that expectation typically changes once you become aware that someone is present.

Exceptions that broaden owner responsibility

The limited duty owed to trespassers has recognized exceptions, and situations involving minors are the most significant. Property features that tend to draw young children, such as a swimming pool or unsecured equipment, can change the analysis even when a child enters without invitation.

When a hazard is man-made and a child may not recognize the danger, an owner who could reasonably expect that presence may need to take protective steps such as installing a barrier. Courts weigh the cost of addressing the risk against the seriousness of the harm a child could suffer.

Established patterns of entry can also raise the level of care owed to adult trespassers. If people routinely cross a defined area and you know about it, a court may look more closely at whether you addressed a hidden danger in that space.

Defenses that limit legal exposure

Should an injured trespasser pursue a claim, the legal status that limited your duty serves as your initial line of defense. You may demonstrate that the individual entered without permission and that your conduct remained within the narrow boundary the law establishes.

The injured party’s own conduct is also material to the analysis. Oklahoma reduces or bars recovery when the person seeking damages bears partial responsibility for the harm, and evidence that the individual scaled a fence or disregarded a posted warning may substantially affect the result.

Open and obvious dangers provide an additional basis for defense. When a risk is sufficiently apparent that a reasonable person would recognize and avoid it, that visibility can weaken the contention that you should have done more.

These defenses depend heavily on the specific facts, which is why prompt documentation is valuable. Legal representation can help you with which option best suits your case.
