The notion of leasing goes back an system extremely long way, back to english feudal system. In that system a concept of ownership was developed that was able to able to include a structure of relations between men and things based not on powers that were absolute, like the Roman dominium. but on a multitude of prerogatives and right of a temporary nature, centering more on the use of property than on the formal title of ownership. The English model has always associated with this concept, which we can define as 'extended'' ownership,a purely 'patrimonial' component, deemed to merit autonomous protection in the legal sphere (Candian,Gambaro&Pozzo,2002; Gambaro1997; Grossi, 1963 ; Megarry Sir Robert & Thompson, 1993 ; Moccia 1999).
