It is not compulsory to register an Agreement of Sell entered between the seller of an immovable property and its buyer. Only the Sale Deed is required to be registered. Though optional, it is advisable to register the Agreement to sell because once it is registered; the buyer’s name will be entered in the encumbrance records. There will be a charge on the property for the advance amount paid to the seller. It will not be possible for the seller to cheat the buyer very easily. The cost of registering an Agreement to sell is very nominal. Applicable Stamp Duty in Karnataka is only Rs. 200/-.
