Licence: Permission to do something on or with someone else”s property which, if it were not for the licence, could be legally prevented or could give rise to an action in tort or trespass. A common example is allowing a person to cross the licensor”s lands, which would otherwise constitute trespass. Licences, unlike easements, may be revoked at will, unless supported by some form of payment or consideration. Licences which are not based on a contract and which are fully revocable are called simple or bare licences.
