There are offences under the Criminal Justice and Public Order Act 1994 Sections 61 and 62 of trespassing on land and trespassing with vehicles. However, in England and Wales certain forms of trespassing, generally those which involve squatters, raves and hunt saboteurs are covered by criminal law. Trespassing is usually a civil wrong and dealt with accordingly. If a visitor misbehaves at any time and refuses to leave when asked to do so by someone with a right to do so (usually the landowner or a representative) then the visitor becomes a trespasser because they no longer have the landowner's permission to be there, even if they entered legally. If the place closes at a certain time and someone is present after that time, they can then be considered to be trespassing. This does not mean that they have a right to be on it at all times - they do not. People in a park will often protest (if asked to leave) that it is public land.

An example of this would be the person who has a ticket to attend a performance, enters the theatre and then, having caused a disturbance, refuses to leave the premises. If you go on to land without the owner's permission, you are trespassing unless there is some right of access for the public, or for you specifically (for example, if you have acquired a right to pass over the land to reach some land of your own). The word trespass covers much more than people usually realise. In some cases, the act of entering the property may have been lawful if permission was given originally, but subsequently become trespass if that permission ends or is withdrawn. Trespass is the wrong (known as a tort in legal terminology) of illegally entering another person's property.
