Agreement to sell vs sale deed: the difference that decides who owns the property
An agreement to sell is a promise; a sale deed transfers title. The difference in stamp duty, registration and ownership every Indian buyer must understand.

People sign an agreement to sell, hand over most of the money, take the keys, and believe they own the property. They do not. An agreement to sell is a promise to transfer ownership in the future; a sale deed is the document that actually transfers it. The gap between the two is where buyers lose money and years in court. This guide sets out what each document is, how they differ on stamp duty, registration and ownership, and what the Supreme Court has said about treating an agreement as if it were title.
What an agreement to sell is
An agreement to sell (also called an agreement to sale or sale agreement) is a contract that records the terms on which a property will be sold: the price, the payment schedule, the possession date, and the conditions each side must meet before the sale is completed. It binds buyer and seller to go through with the sale, and it gives the buyer a remedy if the seller backs out. What it does not do is pass ownership. Section 54 of the Transfer of Property Act is explicit: a contract for the sale of immovable property does not, of itself, create any interest in or charge on that property.
What a sale deed is
A sale deed is the executed, registered instrument that conveys title from the seller to the buyer. When it is signed, stamped, and registered, ownership passes. It is the document you produce to prove you own the property, the document a bank lends against, and the document the next buyer will demand. Under the Registration Act, 1908, a sale deed for immovable property worth ₹100 or more must be registered; an unregistered sale deed does not transfer title and cannot be admitted as evidence of the sale.
Agreement to sell vs sale deed: the differences that matter
- Ownership: an agreement to sell transfers no ownership; a registered sale deed transfers it in full.
- Timing: the agreement comes first and looks forward to a future sale; the sale deed completes the sale in the present.
- Stamp duty: an agreement to sell attracts nominal stamp duty in most states, often adjustable against the final duty; a sale deed attracts the full state stamp duty on the property value, typically in the 5 to 7 per cent range.
- Registration: a sale deed must be registered to be valid; registration of an agreement to sell is optional in most states, though some, such as Maharashtra, require it for certain agreements.
- Remedy on breach: on an agreement, the wronged party can sue for specific performance or damages; on a completed sale deed, the buyer already holds title.
Does an agreement to sell transfer ownership?
No. This is the single point that trips buyers up. Paying the full price and taking possession under an agreement to sell does not make you the owner. Until a sale deed is executed and registered, the title remains with the seller, who can, in the worst cases, sell or mortgage the same property to someone else. Possession is not ownership.
The Supreme Court on treating agreements as title
The practice of transferring property through an agreement to sell bundled with a general power of attorney and a will - the so-called GPA or SA/GPA/Will sale - was addressed by the Supreme Court in Suraj Lamp & Industries v State of Haryana (2012). The Court held that such transactions do not convey title and are not a valid mode of transfer; title in immovable property passes only by a registered deed of conveyance. If you are being sold a property on an agreement plus a power of attorney rather than a clean sale deed, that ruling is the reason to walk away.
What a buyer should do
- Treat the agreement to sell as a conditional step, not the finish line - it protects the deal, not your ownership.
- Keep the final payment tranche tied to execution and registration of the sale deed.
- Verify title, the encumbrance certificate and any charge on the property before you sign the agreement, not after.
- Refuse a purchase structured as agreement-to-sell-plus-power-of-attorney in place of a registered sale deed.
- Register the sale deed and pay the full stamp duty; do not rely on an unregistered or under-stamped deed to save cost.
