The complete dominion, title, or proprietary right in a thing or claim. See PROPERTY. The ownership of a thing is the right of one or more persons to possess and use it to the exclusion of others. In this Code, the thing of which there may be ownership is called “property.” Civ. Code Cal { 654. Ownership is the right by which a thing belongs to some one in particular, to the exclusion of all other persons. Civ. Code La. art 48a Ownership is divided into perfect and imperfect. Ownership is perfect when it is perpetual, and when the thing is unincumbered with any real right towards any other person than the owner. On the contrary, ownership is imperfect when it is to terminate at a certain time or on a condition, or if the thing which is the object of it, being an immovable, is charged with any real right towards a third person; as a usufruct, use, or servitude. When an immovable is subject to a usufruct, the owner of it is said to possess the naked ownership. Civ. Code La. art. 490; Maestri v. Board of Assessors, 110 La. 517, 34 South. 658.
