The term property in common parlance indicates the economic status of a person. Any property is held by an individual to draw out benefit from it. Transfers are made by owners themselves, ostensible owners and the co-owners or we can say joint owners. When two or more persons enjoy common ownership of a property, for example say in a coparcenary, the male members and now even daughters have a common and an equal interest in the ancestral property, any co-owner can transfer his own share in the property to a stranger or another co-owner. And that transferee steps in the shoes of the co-owner (transferor) and gets clothed with all his assets and liabilities. We can say that the transferee becomes the co-owner.
Ownership consists of innumerable number of claims, liberties, powers with regard to the thing owned. When a person owns a property in one time it is called sole ownership, but if the property is owned by more than one person then it is called joint ownership. By means of partition one can have co-ownership changed into sole ownership.
