According to the Legal Information Institute of Cornell University, trespassing is "defined by the act of knowingly entering another person’s property without permission." Trespassing law varies from place to place, but it generally contains similar elements in all of its manifestations.
Certain elements of trespass law allow for some amount of interpretation. For instance, one example given by the Reporters Committee for Freedom of the Press states that reporters and journalists gain implied consent if they are allowed onto a property to ask the owner some questions. Trespassing is typically determined by the owner of the property; however, a renter has allowances to control who is allowed on the property.
