Collective ownership, in its various manifestations dating back over time that have as their object the belonging, use, management of large portions of land for agricultural, pasture or woodland purposes, constitutes another way of possessing these assets by communities concerned, so as to allow the collective use of some real estate while assuring the conservation of the natural environment as a heritage of man and the society in which he lives. Collective ownership, also known as ?civic uses?, has been the subject of important decisions made by Constitutional Court which recognized its belonging to the civil system of Italy, being them real rights relating to real estate. Recently, the legislator intervened to regulate the matter with the law n. 168 of November 20, 2017 on collective domains. A law that recognizes their constitutional significance, their private nature, the fact that they can not be alienated, divided, acquired by prescription and their perpetual destination for agricultural, pasture or woodland purposes.
