Trespassing or civil trespassing differs from criminal trespassing, in the sense that while civil trespassing implies entering someone’s area or property without permission, criminal trespassing is when one chooses to be in that area or property despite knowing that they are not authorized to. For instance, entering someone’s lawn unknowingly may be a trespass but jumping over a fence to enter and ignoring a no-trespassing sign constitutes a criminal trespass. Because of intent, as per state, the degree of punishment for regular trespass and criminal trespass also differ from just warnings to misdemeanor to felony.
