This Practice Note deals with what constitutes ‘premises’, when a potential claimant will be a ‘lawful visitor’ and rules relating to parkland and the countryside. Premises can be land or buildings as well as any fixed or moveable structure and can cover everything from shops, offices, public buildings, aircraft and houses. There are three types of lawful visitor: those with express permission, eg a person you invite into your house, those with implied permission, eg a person entering a shop and those with a right to enter, eg a police officer.
