A Bengaluru buyer in 2026 signed a builder buyer agreement without reading past the first page, trusting the sales team's assurance that it was standard. Two years later, when possession slipped and he looked for the delay penalty, he found the clause was weak and the possession date vaguely worded. The agreement is the one document that binds the developer to specific promises, and the moment to read it closely is before you sign, not after a dispute. This guide walks through the clauses that matter most and what each should say to protect you.

The short answer. The builder buyer agreement, or agreement for sale, is your enforceable contract with the developer, and under RERA it must be executed and registered before you pay beyond ten percent of the price. Read it for a specific possession date, a fair delay penalty, pricing on carpet area, a milestone linked payment schedule, and clear cancellation and refund terms. The trade off for a careful read now is real protection later, so never treat this document as a formality, and get a lawyer to review it before you commit.

The builder buyer agreement, often called the agreement for sale, is the legally binding contract between you and the developer that records exactly what you are buying, at what price, and on what terms. It is the document a regulator or court would look to if anything goes wrong, so its wording, not the brochure or the sales pitch, is what actually protects you. A strong agreement pins the developer to a specific home, a specific date, and specific consequences for failing to deliver. A weak or vague one leaves you exposed. Because it governs the largest purchase most people make, reading and negotiating it carefully is time exceptionally well spent.

When must the agreement be signed and registered?

Under RERA, a developer cannot accept more than ten percent of the property's cost without first executing a written agreement for sale, and that agreement must be registered. This means the agreement should come before any large payment, not after, and a demand for a big sum on only a booking form is a warning sign. The registration gives the document full legal standing. We cover this rule in detail in our guide to the RERA agreement for sale and the ten percent rule. The essential point for this discussion is that the agreement is not optional paperwork you sign later, it is the gateway to paying safely.

Which possession and penalty clauses must you check?

Check that the agreement states a specific possession date, not a vague window or a phrase like within a reasonable time. A firm date is what makes a delay measurable and a penalty enforceable. Then read the delay clause: if the developer misses the date, you should be entitled to interest on the amount you have paid, at a defined rate. Under the model framework this is often the lending rate of a major bank plus a margin, but confirm the figure in your agreement. Crucially, check that the interest the developer owes you for a delay is the same rate you would owe them for a late payment. An agreement that penalises you heavily but the developer lightly is unbalanced and worth negotiating.

How should the payment schedule and carpet area read?

The payment schedule should tie your instalments to construction milestones, so you pay as the building actually rises rather than on arbitrary dates disconnected from progress. A schedule that front loads payments before matching construction shifts risk onto you, so read it carefully. On area, the agreement should price the flat on carpet area, the net usable space within your walls excluding external walls, shafts, and exclusive balconies or terraces, as RERA requires. Confirm the carpet area figure in the agreement matches what you were shown, and that the price is anchored to it. These two clauses, the payment schedule and the area basis, are where a buyer most often overpays or takes on hidden risk without realising. A schedule tied to slabs poured and floors completed keeps the developer accountable, since money follows visible progress you can check on site.

What cancellation, refund, and default clauses matter?

Read the cancellation and refund terms before you sign, not when you need them. The agreement should state clearly what happens if you cancel, how much is refundable, and over what timeline, as well as the developer's obligations if the project itself is cancelled or abandoned. Watch for a forfeiture clause that lets the developer keep a large share of your money on cancellation, which can be onerous. Check the default provisions on both sides, so that the consequences of a missed payment by you are proportionate and mirror the developer's own obligations. A fair agreement treats both parties symmetrically, and clauses that are heavily one sided against the buyer are exactly what a lawyer should flag before you sign.

Pay particular attention to any clause that lets the developer alter the deal after you have signed. Some agreements reserve wide rights to change the layout, increase the area and therefore the price, adjust common amenities, or shift the possession date at the developer's discretion. A well drafted agreement limits such changes and requires your consent for anything material, while a weak one hands the developer flexibility you will later regret. Read these clauses as carefully as the price itself, because they decide whether the home you finally receive is the one you agreed to buy or a quietly altered version of it.

What else should you look for in the agreement?

Beyond the headline clauses, read the fine print that shapes daily life and long term cost. Check the specifications and amenities, so the fittings, materials, and facilities promised in the brochure actually appear in the agreement, since only what is written is enforceable. Look at the maintenance terms, including who runs the common areas and how charges are set. Read the force majeure clause, which excuses delay for events beyond the developer's control, and make sure it is not so broad that it swallows the possession commitment. Also check the terms on transferring or assigning your allotment, and any clause requiring your consent for changes to the plan. The details here often decide how the home actually feels to own.

One more habit protects you: make sure every promise that persuaded you is written into the agreement, not left in a brochure or a salesperson's word. A club, a landscaped garden, a particular flooring, a covered parking space, a timeline for amenities, all of these are enforceable only if they appear in the contract. Brochures often carry a disclaimer that they are indicative and not binding, so a feature that exists only there may never materialise. Before you sign, list what actually convinced you to buy, then check each item against the agreement, and ask for anything missing to be added in writing.

Your builder buyer agreement checklist

Work through these seven checks before you sign.

1. Confirm the agreement is executed and registered before large payments.
2. Check for a specific possession date, not a vague window.
3. Read the delay penalty and confirm it matches your default rate.
4. Ensure pricing is on carpet area, with the figure stated.
5. Verify the payment schedule is linked to construction milestones.
6. Read the cancellation, refund, and forfeiture terms carefully.
7. Have a property lawyer review the agreement before you commit.

Where do you get the agreement reviewed?

Get the agreement reviewed by a property lawyer before you sign, because the cost of an hour of review is trivial against the value of the home and the risk of a one sided clause. Understanding your underlying rights helps you read the document with the right lens, which our guide to your rights as a homebuyer under RERA sets out, and the timing of the agreement is governed by the ten percent rule discussed above. Whether you are buying a first flat or a home in a project such as Embassy Grove in Kodihalli, the agreement is where your protection is written, so read it as if everything depends on it, because it does.

Frequently asked questions

When must a builder buyer agreement be signed?

Under RERA, the developer cannot accept more than ten percent of the property's cost without first executing a written agreement for sale, which must also be registered. So the agreement should precede any large payment. If a developer asks for a big sum on a booking form, treat it as a warning sign and insist on the registered agreement first.

What is the most important clause to check?

There is no single clause, but the possession date and the delay penalty are among the most important, alongside the area basis and payment schedule. Insist on a specific possession date, and confirm the delay interest owed to you matches the rate you would owe on a late payment. A firm date and a balanced penalty make the promise enforceable.

Should the flat be priced on carpet area or super built up area?

On carpet area. RERA requires pricing based on carpet area, the net usable space within your walls, excluding external walls, shafts, and exclusive balconies or terraces. Confirm the carpet area figure matches what you were shown and that the price is anchored to it. Pricing on super built up area is what the rule was meant to prevent.

Do I need a lawyer to review the agreement?

It is strongly advisable. A property lawyer reads the agreement for one sided clauses, checks the possession, penalty, and refund terms, and spots issues a buyer can easily miss. The fee is small against the value of the home. Never sign a builder buyer agreement under time pressure without a review, since its terms bind you afterwards.
