How is "trespass" defined under Texas law?

The correct definition of "trespass" under Texas law is primarily concerned with the act of entering onto another person’s property without permission. This concept is straightforward, as it highlights the importance of respecting property boundaries and the rights of property owners. When someone enters a property without the owner’s consent, it constitutes a violation of the owner’s right to exclusive possession of that property, which is foundational to property law.

Elements such as interfering with property rights, using someone else's property for personal gain, or failing to vacate a property after legal notice may involve different legal concepts or remedies, but they do not encapsulate the core definition of trespass. Trespass is specifically about the unauthorized entry, which is why option A is the most accurate representation of the legal definition within Texas law.
