Trespass Definition

The act of entering or remaining on someone else’s property without permission. Although it usually refers to real estate, trespass can also apply to personal property, such as cars or boats. Trespassing is a tort (a civil wrong, which the property owner can sue over), and it can be a crime if done intentionally. Examples of trespass include dumping debris on another's property or hopping a fence to get into someone else’s yard.
