Limited Consent Exceeded by Force
Tanner Thompson received permission from Taliah Tang to enter her trailer only during daytime hours to retrieve tools. After sunset Tanner removed a board nailed across a window and inserted a pry bar to reach a locked safe inside the bedroom area. The limited consent did not authorize entry by force at night, so the entry constituted a trespass that satisfied the breaking element for burglary analysis.
Force Used to Terminate Trespass
Tori Taylor believed Thomas Thompson was unlawfully driving her trailer out of a fenced freight yard. She ordered a guard to block the path and the guard shoved Thompson aside. Because Thompson was attempting to recapture property amid a bona fide claim-of-right dispute, the use of force was not justified under the defense-of-property rules.

Intentional Entry Without Harm
Theresa Tucker walked across Tundra Resources' posted field to reach a neighboring parcel. The company had not consented and no damage occurred. The intentional entry onto land in the company's possession subjected Tucker to liability for trespass regardless of the absence of harm.
Force Creating Substantial Danger
Thaddeus Tran climbed a fence to retrieve a trailer he claimed Triumph Manufacturing had wrongfully impounded. A guard stood between Tran and the trailer. Tran knew that forcing the guard aside would expose the guard to serious bodily harm, rendering the use of force unjustified.
Entry Despite Reasonable Mistake
Taliah Tang entered Trailblazer Airlines' hangar believing she held a valid right to inspect equipment. The belief was mistaken and not induced by the airline. The intentional entry still rendered Tang liable for trespass even though the mistake was reasonable.
Continued Presence After Privilege Ends
True North Logistics left a storage container on Theresa Tucker's land under a temporary license that expired. After the license terminated the company failed to remove the container. The continued presence of the chattel on the land constituted a trespass.
Common questions
Frequently Asked
5
Does trespass require proof that the entry caused actual harm to the land?+
No. Liability for trespass arises from the intentional entry itself even when the presence on the land causes no harm to the land, its possessor, or any protected interest.
Supporting sources
Is a reasonable mistake about the right to enter a defense to trespass?+
No. An intentional entry remains trespassory even when the actor holds a mistaken belief of law or fact, however reasonable, that he is entitled to enter.
Supporting sources
When does consent to enter fail to prevent a trespass finding?+
Consent limited to certain times does not authorize entry by force at other times, and consent procured by fraud or threats is ineffective.
Supporting sources
May a person use force to terminate a trespass when doing so would expose the trespasser to serious bodily harm?+
No. The use of force to prevent or terminate a trespass is not justifiable if the actor knows that exclusion will expose the trespasser to substantial danger of serious bodily harm.
Supporting sources
Does a trespass occur when a chattel remains on land after consent ends?+
Yes. Continued presence of a structure or chattel after consent or privilege has terminated constitutes a trespass.
