Section 54 of the Transfer of Properly Act considered with the principles laid down by various jurists as referred in the judgment leads the Court to conclude that in an effective transfer of ownership by sale of an immovable property, not only registration of the sale deed but also the possession factor must be taken into consideration, simply because without transfer of the right to possession, the transfer of ownership of a property remains incomplete. However, in case of a sale, the mode and also the requirement of delivery of possession may vary depending on the attending circumstances of a particular transfer and also the intention of the parties.
