250. Title is the means by -which the ownership of real property is acquired and held. This is either

The fact which in any case gives or creates ownership over real property is called title. Title signifies the manner in which estates and interests in land are acquired. At the beginning of real-property law in any country there must be an original acquisition of title to land. After title has been thus acquired all subsequent acquisitions of title to the same land must be by transfer of the title.
Descent and Purchase.
All titles are said to be acquired by descent or by purchase. Purchase means more than mere buying, it includes the acquisition of title by devise or by gift. In short title by purchase means title acquired in all ways except by descent.
