a price. In a sale there is an absolute transfer of all rights in the properties sold. No rights are left in the transferor. The price is fixed by the contract antecedent to the conveyance. Price is the essence of a contract of sale. There is only one mode of transfer by sale in regard to immovable property of the value of Rs.100/- or more and that is by a registered instrument. Payment of entire price is not a condition precedent for completion of the sale by passing of title, as Section 54 of the Transfer of Property Act, 1882 (“the Act”, for short) defines “sale” as “a transfer of ownership in exchange for a price paid or promised or part-paid and part-promised.” If the intention of parties was that title should pass on execution and registration, title would pass to the purchaser even if the sale price or part thereof is not paid.

Normally, ownership and title to the property will pass to the purchaser on registration of the sale deed with effect from the date of execution of the sale deed. But this is not an invariable rule, as the true test of passing of property is the intention of parties.

The answer to the question whether the parties intended that transfer of the ownership should be merely by execution and registration of the deed or whether they intended the transfer of the property to take place, only after receipt of the entire consideration, would depend on the intention of the
