A document is a document if: In cases where you have purchased and taken possession of property under a sales contract, title to the property remains in the hands of the developer, unless a certificate of sale has been executed a posteriori and registered in accordance with the Indian Registration Act. Thus, it is clear that a title to immovable property can only be transferred by a deed of sale. In the absence of a duly stamped and registered deed of sale, the buyer of the property does not have the right, title or interest in a property. A contract of sale is a contract for the sale of real estate in the future. This agreement defines the conditions under which the property is transferred. . . .
