Fraudulent Entry After Hours
Umeko Uchida told the night manager she was a delivery driver with an urgent package. Once inside the warehouse, she used a crowbar to force open a locked storage room. The manager had consented only to daytime deliveries, so the nighttime entry by fraud counted as an unlawful trespass that satisfied the breaking element for burglary.
Force Used to Stop Intruder
Uriah Urban saw Ulysses Ucelli climbing the fence onto his commercial lot at night. Urban pushed Ucelli off the fence and back onto the sidewalk. Because Urban reasonably believed the land was in his possession, the force was justified to terminate the unlawful trespass.

Unity Underhill deliberately stepped over the marked property line onto land occupied by Uptown Apparel to take a shortcut. The company had posted clear no-trespassing signs. Underhill's intentional entry without consent or privilege made her liable for trespass even though she caused no damage.
Force That Risks Serious Harm
Una Ueda discovered a stranger inside her fenced yard and considered releasing her guard dogs. She knew the dogs would likely cause serious injury. Because the use of that force would expose the trespasser to substantial danger of serious bodily harm, the force was not justifiable.
Harmless but Intentional Entry
Ulysses Ulrich walked across the corner of a neighbor's vacant lot to reach a public path. The neighbor was in possession of the lot. Ulrich's intentional presence on the land constituted an unlawful trespass even though the entry caused no physical harm.
Remaining After Consent Ends
Ugo Ucelli parked a trailer on land owned by Ultimate Solutions with permission limited to one week. After the week expired, the company revoked consent and demanded removal. Ucelli's continued presence of the trailer after the privilege terminated constituted an unlawful trespass.
Common questions
Frequently Asked
5
Does trespass require proof of actual damage to the land?+
No. Liability for trespass arises from an intentional and unprivileged entry or continued presence even when the land, possessor, or things on the land suffer no harm.
Supporting sources
When does consent fail to prevent an entry from being a trespass?+
Consent limited to certain times does not authorize entry at other times, and consent obtained by fraud or threats is ineffective, so the entry remains an unlawful trespass.
Supporting sources
May a possessor use any amount of force to stop a trespass?+
No. Force is not justifiable if the actor knows that excluding the trespasser will expose the trespasser to a substantial danger of serious bodily harm.
Supporting sources
Does remaining on land after consent ends count as trespass?+
Yes. Continued presence of a structure or chattel after consent or privilege has terminated constitutes an unlawful trespass.
Supporting sources
Is an entry a trespass if the actor mistakenly believes the land is open to the public?+
Yes. An intentional entry is a trespass even when the actor acts under a reasonable but mistaken belief of fact or law that the land is open or that the actor is entitled to enter.
