Trespass is the unprivileged, unauthorized or unconsented to entrance onto and damaging property owned or occupied by another person. The property could be in a natural condition, such as a park or wild landscape, or improved with dwellings or buildings. You could be prohibited from entering the land altogether or you could exceed the scope of your invitation, i.e. entering onto property after closing time or going around or over a fence meant to limit access; any of which would constitute a trespass. Trespass is a physical invasion of property, which means that it could manifest itself an many forms. A person walking onto another’s property, throwing something onto another’s property or causing some phsyical force to invade the property (fire, or toxic gas) are common examples.
