People use the two terms interchangeably and then discover, sometimes years later, that they never became the owner.
Agreement to sell
A contract recording that the seller will transfer the property on stated terms at a future date, usually on payment of the balance. Section 54 of the Transfer of Property Act, 1882 is explicit: a contract for the sale of immovable property does not, of itself, create any interest in or charge on such property. It gives you contractual rights, not ownership.
That does not make the agreement worthless. Section 53A of the same Act protects a buyer who has taken possession under a written contract and has performed, or is willing to perform, his part of it. But it is a shield to defend possession, not a source of title, and it does not let you sell the property on. Our fuller comparison of the sale agreement and the sale deed works through how the two documents are stamped, registered and enforced.
Sale deed
The instrument that actually conveys title. For immovable property worth more than one hundred rupees it must be registered under the Registration Act, 1908, and stamp duty must be paid at the applicable rate. Only on registration does ownership pass.
How the sale deed actually gets registered
The mechanics come from the Registration Act, and each of them is somewhere a transaction stalls.
- Where. Section 28 requires a document affecting immovable property to be presented in the office of the sub-registrar within whose sub-district the property, or some part of it, is situate
- When. Section 23 allows four months from the date of execution to present it. Section 25 lets the Registrar condone a delay beyond that on payment of a fine, but only for urgent necessity or unavoidable accident, so it is not something to plan around
- By whom. Section 32 requires presentation by a person executing or claiming under the document, or by a representative or an agent duly authorised by a power of attorney
In Karnataka the appointment is booked through Kaveri Online Services, duty and the registration fee are charged on the consideration or the guidance value, whichever is higher, and within BBMP limits a valid e-khata has to exist before the transaction can be registered at all. Both sides attend with identity and PAN, two witnesses attend, and biometrics are captured. Where the price crosses the threshold set under the Income-tax Act, 2025, which replaced the repealed Income-tax Act, 1961 with effect from 1 April 2026, deducting tax at source and depositing it is the buyer's job. Confirm the current slab and the guidance value for your specific property before you fix a budget, because both are revised from time to time.
| Agreement to sell | Sale deed | |
|---|---|---|
| Transfers ownership | No | Yes |
| Registration | Not compulsory in most cases | Compulsory |
| Stamp duty | Nominal | Full rate on market value |
| Remedy on breach | Specific performance or damages | Title suit |
What the agreement is genuinely for
- Locking the price and terms while you complete due diligence and arrange finance
- Recording the payment schedule and the date for execution of the sale deed
- Fixing what happens on default on either side, including forfeiture of advance
- Giving you the right to sue for specific performance under the Specific Relief Act if the seller refuses to complete. Note the limitation period for that suit is generally three years from the date fixed for performance, or from when the refusal is known
On that last point, the Specific Relief Act, 1963 was amended in 2018 and specific performance is no longer the openly discretionary remedy it once was. What has not changed is that a buyer must plead and prove readiness and willingness to perform his own side of the bargain throughout, which in practice means having the balance arranged and being able to demonstrate it. A buyer who went quiet for two years and then sued rarely does well.
Should the agreement itself be registered
It is not compulsory in most cases, and most Bengaluru agreements are not registered. There is a real argument for registering one where the gap to the sale deed is long or the sum at stake is large, because a registered agreement shows up on the encumbrance certificate and that alone makes a double sale far harder to pull off. Duty on an agreement to sell is set by the state schedule and is ordinarily a fraction of the duty on the conveyance, and in some cases it is adjusted against the duty later paid on the sale deed. Get the figure for your own transaction before deciding. Where you choose not to register, at least keep every payment in the banking channel and take the seller's written acknowledgement for each instalment.
Buying on an unregistered agreement plus a general power of attorney and a will, and not executing a sale deed, in order to save stamp duty. The Supreme Court in Suraj Lamp & Industries v. State of Haryana (2011) held that such transactions do not convey title. Buyers in these arrangements own nothing, cannot get a loan, and cannot pass good title on.
The safe version of the same transaction is not complicated. Verify the title, sign a properly drafted agreement to sell, complete with a registered sale deed. The documents to verify before you sign either one are the same every time, and the duty saved by the shortcut is invariably less than the cost of the suit that follows it.
