[410]. The full power of alienation and disposition is an almost invariable element in the right of ownership, but cannot be regarded as essential, or included in the definition of it. A married woman subject to a restraint on anticipation is none the less the owner of her property, though she cannot alienate or encumber it.

Austin (II. p. 790) defines the right of ownership as a “right indefinite in point of user, unrestricted in point of disposition, and unlimited in point of duration, over a determinate thing.”
