This document discusses the concept of ownership and its evolution from possession. It distinguishes between possession and ownership, with ownership conferring absolute rights over a thing and possession implying only physical control. Two main theories of ownership are described - one viewing it as the relation between a person and a thing, the other as the relation between a person and the rights vested in them. Different types of ownership are defined, including sole vs co-ownership, legal vs equitable ownership, vested vs contingent ownership, and absolute vs limited ownership. Trust and beneficial ownership are explained as situations where legal ownership is held by a trustee for the benefit of the beneficial owner.
