Trespass refers to the act of entering someone's property without permission. This can include physical intrusion onto land or property, as well as unauthorized use of someone's resources. Trespassing is generally considered a violation of property rights and can lead to legal consequences. In many jurisdictions, trespass laws are designed to protect property owners from unwanted intrusion. There are different types of trespass, such as criminal trespass, which involves entering a property with the intent to commit an illegal act, and civil trespass, which focuses on the unauthorized entry itself.
