Agreement for sale vs sale deed

You will sign two documents for the same flat, months or years apart, and only one of them makes you the owner. The agreement for sale is what you sign first, usually soon after booking: a long, detailed contract that fixes the price, the plan and the date. The sale deed is what you sign last, at the sub-registrar’s office (our registration-day guide walks through it): a shorter document that actually transfers the property. Confusing the two – treating the agreement as if it were the deed, or the deed as a formality after the “real” contract – is where buyers get into trouble.

This guide sets out the legal difference between them, walks through what Karnataka’s model agreement for sale actually says clause by clause, and covers what changes when that agreement becomes a registered sale deed. Where we have already covered a topic in depth – the full cost sheet, what possession dates mean, carpet area – we link to that guide rather than repeat it here.

The legal difference

Section 54 of the Transfer of Property Act, 1882 is where this comes from. As the Supreme Court quoted it in Suraj Lamp & Industries v State of Haryana (2011): “A contract for the sale of immovable property is a contract that a sale of such property shall take place on terms settled between the parties. It does not, of itself, create any interest in or charge on such property.” The Court’s own summary is blunter still: “Section 54 of TP Act makes it clear that a contract of sale, that is, an agreement of sale does not, of itself, create any interest in or charge on such property” – a position it traced back to its own 1977 ruling in Narandas Karsondas v S.A. Kamtam. The judgment adds a detail worth keeping in mind through the rest of this guide: “an agreement of sale, whether with possession or without possession, is not a conveyance.” Whether or not you have been let into the flat, the agreement is still only a promise.

Why registration is compulsory

Even though it transfers nothing, the agreement itself must still be registered. Two rules push in the same direction from different angles. The Registration Act, 1908, section 17(1)(b), requires registration of “other non-testamentary instruments which purport or operate to create, declare, assign, limit or extinguish…any right, title or interest…of the value of one hundred rupees and upwards, to or in immovable property” – which an agreement for sale falls within, whatever section 54 says about it not transferring title outright. RERA section 13(1) makes the same point from the buyer’s side: a promoter “shall not accept a sum more than ten per cent…as an advance payment or an application fee…without first entering into a written agreement for sale…and register the said agreement for sale, under any law for the time being in force.”

Section 13(2) goes on to say the agreement “shall be in such form as may be prescribed”. In Karnataka that form is fixed: a 2020 amendment to the state’s RERA rules inserted Rule 8A, which reads, “For the purpose of sub-section (2) of section 13…the agreement for sale shall be in the Format as per Annexure-A.” The same rule adds that anything you signed earlier – an application form, an allotment letter – “shall not be construed to limit the rights and interests of the allottee under the agreement for sale or under the Act.” A booking form is not a substitute for the registered agreement, and does not cap what you are entitled to once you have one.

Reading the model agreement

Every K-RERA registered project in Karnataka uses the same form, Annexure-A. That is useful for you: instead of comparing wording between builders, you can learn the one document and know what to look for wherever you buy. Eleven parts of it are worth reading with particular care.

Two of these deserve a longer look. On possession and delay, clause 7.1 fixes a single date and defines force majeure narrowly: “war, flood, drought, fire, cyclone, earthquake or any other calamity caused by nature affecting the regular development of the real estate project.” If the promoter still misses the date outside that list, clause 7.6 gives you a choice: walk away for a full refund with interest and compensation, or stay and take interest for every month of delay until you get possession, paid within 60 days of falling due. Our guide to possession dates covers what that date should look like on a RERA filing before you even get to the agreement.

On cancellation, the three clauses cut differently. Under 7.5, if you cancel without any fault of the promoter’s, the promoter keeps your booking amount and returns the rest within 60 days – a real cost to changing your mind. Under 9.2, if the promoter is in default, you get a full refund with interest, or you can stay and take monthly interest instead. Under 9.3, if you miss a run of payment demands, the promoter can cancel on you, keeping the booking amount and interest due, but must give 30 days’ notice before doing so. Read all three before you sign, not just the one that feels relevant at booking.

1. The parties. Whoever is named as Promoter is who is legally bound to you – check this against the RERA registration, especially in a joint development.
2. Carpet area, not saleable area. The Total Price in clause 1.2 is stated against this figure. If a brochure quotes a bigger number, it is measuring something else.
3. “Inclusive” has a specific meaning here. Clause 1.2’s Explanation lists exactly what the price already covers – check nothing you were promised verbally is missing from it.
4. The payment plan is a separate schedule. Read Schedule C itself, not just this reference to it, for which construction stage triggers which instalment.
5. A calendar date, not a duration. “36 months from booking” is not a possession date under this form; it should read like the one above.
6. A rule reference, not a number the builder chose. If this field names a fixed percentage instead of the Rules, ask why.
7. Where it gets registered. The same office that will later register your sale deed.

What the sale deed contains

The sale deed is shorter than the agreement, but it is the document that actually does the work. It carries a full schedule of the property – survey number, extent, and the flat’s own description – your undivided share of the land and common areas, the parking you paid for as part of the same indivisible unit under clause 1.9, and the recitals of title the promoter warranted back in clause 8 of the agreement, now stated as fact rather than promise. Registering it needs a current e-khata, which Bengaluru has required since late 2024; our documents guide covers getting one. Who signs depends on who held title to your flat’s share in the first place – ordinarily the promoter, though where a project sits on someone else’s land the actual titleholder must also be party to the deed, in person or through a valid, unrevoked power of attorney.

The deed of apartment

Where a building falls under the Karnataka Apartment Ownership Act, 1972, the sale deed is paired with a second document, the deed of apartment. The Act treats each flat as its own piece of property from the moment its owner files a Declaration: “Each apartment, together with its undivided interest in the common areas and facilities appurtenant to such apartment, shall for all purposes constitute…property” that the owner may transfer, “subject to the provisions of this Act and a Deed of Apartment in relation to his apartment.” That undivided share is fixed as a percentage in the building’s Declaration, and section 6 is specific that it “shall not be altered without the consent of all the apartment owners.”

Section 12 sets out what the deed of apartment itself must contain: the land description, “the apartment number…and any other data necessary for its proper identification”, the permitted use, “the percentage of undivided interest appurtaining to the apartment in the common areas and facilities”, and any further detail the parties want on record. Section 13 requires it to be registered, alongside the Declaration and the building’s floor plans, “under the Registration Act, 1908” – the same compulsory-registration principle that applies to the sale deed, applied to the flat’s share of the building as a whole.

What changes at the deed

Three things move between the two documents. The carpet area goes from a stated figure in clause 1.2 to a confirmed one: the agreement obliges the promoter to reconcile it once the occupancy certificate is issued, refund any shortfall with interest within 60 days, and charge for growth of up to 3% at the same rate per square foot already agreed – not a renegotiated one. Title goes from a warranty to a recital: clause 8’s promises about clear title and no encumbrances become the deed’s own statement of what is being conveyed, which is why your own title search should not wait until this stage to begin. And maintenance responsibility moves from the promoter, funded out of the price you already paid under clause 1.2, to the association, once the completion certificate is issued and the common-area documents are handed over under clause 7.4.

The duty on each

Karnataka’s Stamp Act taxes an agreement for sale under Article 5(e), and splits it exactly along the line the Supreme Court drew – with possession, or without. Article 5(e)(i), where “possession of the property is delivered or is agreed to be delivered before executing the conveyance”, is dutiable at “the same duty as a conveyance”, the full rate. That is unusual for a new flat: possession normally follows the sale deed, not the agreement. Article 5(e)(ii), where possession is not delivered, is the one that applies to almost every flat bought off-plan or under construction. After a 2024 amendment substituted the numbers, it now reads “fifty paise for every one hundred rupees or part thereof on the market value equal to the amount of consideration…but not less than rupees Five hundred” – 0.5%, with no upper limit. The sale deed is taxed at the full rate. Because the two documents are taxed differently, the bill arrives in two parts. On a ₹1 crore flat, at the rates in force on 10 Sep 2026:

₹50,000 on the agreement, and ₹7.6 lakh on the deed, come to ₹8.1 lakh together – most of it due only at the end, when the deed is registered. Our full cost guide breaks the ₹7.6 lakh down into stamp duty, cess, surcharge and the registration fee, and covers GST and the builder’s own charges on top.

The tripartite loan agreement

If you are borrowing to pay for a flat still under construction, some banks lend through what RBI calls an “innovative Housing Loan Scheme” – upfront disbursal to the builder, with the bank or the builder covering the EMI or interest for a period, “popularly known by various names like 80:20, 75:25 schemes.” RBI’s directions note this “might include signing of tripartite agreement between the bank, the builder and the buyer”, and are direct about the risk: such schemes “are likely to expose the banks as well as their home loan borrowers to additional risks”, including a dispute between you and the builder, or a delayed payment by the builder during the covered period showing up as a mark against your own credit history, since “information about servicing of loans get passed on to the CICs on a regular basis.” Read a tripartite agreement as carefully as the sale agreement itself: it decides who is actually paying your EMI, for how long, and what happens to your credit report if they do not. Our home-loan guide covers how disbursal against a construction-linked plan normally works.

Before you sign

• Check the carpet area in clause 1.2 against the figure on the RERA filing, not the brochure.
• Read the payment plan itself, Schedule C, for which stage triggers which instalment.
• Confirm the possession date is one fixed date, with force majeure limited to natural calamities.
• Check the interest clause cites Karnataka RERA Rule 16, not a rate the builder has written in.
• Read all three cancellation clauses, not just the one that seems to apply today.
• Verify title yourself; clause 8’s promises are not proof.
• Get any tripartite loan agreement’s terms in writing before your EMIs or credit score depend on it.
• At the deed, check the undivided share and parking match what clause 1.2 and 1.9 promised, and that the khata is ready to follow.
