How to read builder-buyer agreement clauses against records

The 90-page PDF that lands with "please sign by Friday"

You paid the booking amount on an under-construction flat in your target locality — maybe in Pune, Bengaluru, Noida, or Hyderabad — and a few weeks later, an email arrives with a PDF attachment running well past ninety pages: the builder-buyer agreement (BBA). The covering note is friendly but urgent — "please review and sign by Friday so we can proceed to registration." You open it, scroll through dense clauses about possession dates, area calculations, penalty formulas, and cancellation terms, and quietly panic. You are not a lawyer. You do not know which of these ninety pages actually matter, and you have no easy way to tell whether what the builder has written matches what they are legally required to have declared to the regulator.

Here is the good news: you do not need to become a lawyer to do a meaningful first pass on a BBA. Since the Real Estate (Regulation and Development) Act, 2016 (RERA) came into force, every registered project has a public RERA declaration — carpet area, possession timeline, sanctioned plans, and more — filed with the state regulator. Your BBA's key numbers should be consistent with that public declaration. This article walks through how to open your state's RERA listing, what to compare it against clause by clause, and how to build a personal record of what you found — the kind of private due-diligence record DrawMagic's live buyer workspace at /buyer/dream-home is designed to help you keep as you work through this decision, alongside our evolving buyer intelligence workspace that is shipping soon to help organise these facts further.

What a BBA is, and why it must agree with the RERA declaration

A builder-buyer agreement (also called an Agreement for Sale) is the contract that sets out the terms on which a developer will construct and hand over a specific unit to you: price and payment schedule, carpet area, possession date, penalties for delay, and the process for cancellation or transfer. Under RERA, several states require that once a buyer has paid 10% or more of the total price, a registered Agreement for Sale must be executed — this is a public statutory requirement, and its precise mechanics can vary somewhat by state, so treat any specific percentage or timeline as accurate "as of" the date you check the relevant RERA rules for your state.

The critical link for a buyer is this: the same project has already made statutory declarations to the state RERA authority at the time of registration — the sanctioned carpet area of each unit type, the declared completion/possession date, the layout and approved plans, and the promoter's registration number. Your BBA's clauses on these same points should be consistent with what is publicly declared. If they diverge, that is a fact worth raising in writing before you sign, not something to assume away.

Step-by-step: cross-checking your BBA against the RERA listing

1. Find the project's RERA registration number. It should appear on the builder's marketing material, brochure, and BBA itself. If you cannot find it, ask the developer directly — a registered project is required to display this number.
2. Open your state's RERA portal (for example, MahaRERA for Maharashtra, K-RERA for Karnataka, UP-RERA for Uttar Pradesh, TS-RERA for Telangana) and search using the registration number or project name.
3. Note the RERA-declared carpet area for your unit type and compare it, unit-for-unit, against the carpet area stated in your BBA. Use the carpet area calculator to sanity-check the numbers if the agreement mixes carpet, built-up, and super built-up terminology, which can otherwise obscure a mismatch.
4. Note the RERA-declared completion/possession date and compare it against the possession clause in your BBA — including any "grace period" language the BBA adds on top.
5. Compare the sanctioned layout/plans referenced in the RERA filing against the plan annexed to your BBA — the unit number, floor, and orientation should match exactly.
6. Check parking, common-area, and amenity clauses in the BBA against what is described in the RERA project brochure filed with the regulator, since amenities are sometimes described more generously in sales brochures than in the binding filed declaration.
7. Write down every discrepancy you find, with the date you checked, and raise it with the developer in writing before signing — email is preferable to a verbal conversation, since it creates a dated record.

Reading table: BBA clause, what to check it against, and where to look

State variation: model agreements and stamp duty

Not every state implements RERA identically. Maharashtra, for instance, prescribes a model Agreement for Sale format under MahaRERA rules that developers in the state are expected to follow closely, which can make clause-by-clause comparison somewhat easier because the structure is more standardised. Other states may allow more variation in drafting, which means you should read the actual clause language carefully rather than assuming a "standard" format applies everywhere.

Stamp duty and registration charges on the Agreement for Sale also vary by state and change from time to time — Maharashtra, Karnataka, and Uttar Pradesh each publish and periodically revise their own rates. Rather than relying on a rate quoted in a brochure or by the builder's sales team, check the current rate on your state's registration/Inspector-General of Registration (IGR) portal at the time you are ready to register, since quoting a specific percentage here would risk being out of date by the time you read it.

A realistic scenario: a Pune buyer catches a possession-date mismatch

A first-time buyer in Pune is reviewing the BBA for a two-bedroom unit in a project registered with MahaRERA. The BBA states a possession date, followed by a separate clause granting the developer a further "grace period" of several months beyond that date before any penalty clock starts. Before signing, the buyer opens the MahaRERA portal, searches the project's registration number, and notes the RERA-declared completion date on file.

The RERA-declared date and the BBA's stated possession date are broadly consistent, but the additional grace-period language in the BBA is not something the buyer can independently verify against the RERA filing — it is a contractual add-on rather than a regulatory fact. Rather than assuming this is standard or fine, the buyer emails the developer asking for written clarification on exactly how the grace period interacts with the RERA-declared date and the delay-penalty clause, creating a dated record of having raised the question before signing. This is exactly the kind of fact-plus-source-plus-date approach that turns a scary 90-page document into a manageable checklist.

Clause-by-clause reading guide

• Possession clause: Note the exact date, and separately note any grace period, force-majeure carve-outs, or conditions attached to that date (e.g., "subject to force majeure and circumstances beyond the promoter's control").
• Area & loading clause: Confirm whether the price is based on carpet area (as RERA requires it be quoted) and check the loading factor used to arrive at any "saleable" or "super built-up" figure quoted elsewhere in your documents.
• Delay/penalty clause: Check what interest rate or compensation applies if possession is delayed beyond the committed date, and whether it is symmetrical with what you would owe the developer for a delay in your own payments.
• Cancellation/forfeiture clause: Note the conditions under which the developer can cancel your allotment and what portion of your payment, if any, would be forfeited.
• Alteration clause: Check what rights the developer has reserved to make changes to the sanctioned plan, layout, or specifications, and whether such changes require your written consent.
• Transfer clause: Note the conditions and any fee for transferring or reselling your allotment before possession.

Pro tips

• Get every clarification in writing — a verbal assurance from a sales executive carries no weight if a dispute arises later.
• Keep dated screenshots of the RERA portal listing alongside your BBA copy, since project details on public portals can be updated over time.
• Never assume the glossy brochure describes the same terms as the binding BBA — read the BBA itself, clause by clause.
• Use the carpet area calculator whenever a document mixes carpet, built-up, and super built-up area terms, since that is one of the most common sources of confusion in a BBA.
• If a clause is unclear or seems one-sided, ask a lawyer to review it rather than relying on your own reading alone for anything with financial consequences.

Common mistakes to avoid

• Signing a payment-linked Agreement for Sale before checking that the project's RERA registration is current and the declared numbers match your BBA.
• Focusing only on the price and payment schedule while skimming past the possession, penalty, and cancellation clauses.
• Assuming the brochure's amenity descriptions are legally binding when the BBA itself is silent or vaguer on the same points.
• Treating a "grace period" clause as insignificant, when it can meaningfully shift the effective possession timeline.
• Not keeping a dated record of your own review, which makes it harder to point back to what you actually agreed to if a dispute arises months or years later.

Integration with your DrawMagic workspace

DrawMagic's buyer workspace at /buyer/dream-home is a private, voice-first companion where you can capture what matters to you — budget, locality, timelines — as part of building your own record while you evaluate a purchase, not as a broker-mediated interaction. As you review a BBA, jot down the RERA registration number, the carpet area and possession date you found, and any discrepancy you raised with the developer. Our evolving buyer intelligence workspace — shipping soon — is designed to help organise these official-record facts and their as-of dates alongside your personal notes in one place. Either way, sign up to get started at drawmagic.com/buyers.

Value note

Reading the RERA portal and comparing it to your BBA costs nothing but time — the portal is public and free to search. DrawMagic does not charge for this kind of record-keeping either; what we offer is a private place to keep your own notes and dated facts together, consistent with the consent-first approach to your data described on our responsible AI page, informed by frameworks like the Deloitte India commentary on the DPDP Rules, 2025, on keeping personal data handling consent-first.

Key Takeaways

• A builder-buyer agreement's carpet area and possession date should be consistent with the same project's public RERA declaration — compare them clause by clause.
• Find the project's RERA registration number and search your state's RERA portal (MahaRERA, K-RERA, UP-RERA, and others) to see the filed declaration.
• Use the carpet area calculator to catch mismatches when a document mixes carpet, built-up, and super built-up area terms.
• Pay close attention to the possession clause, including any grace-period or force-majeure language layered on top of the headline date.
• Model Agreement for Sale formats and stamp duty rates vary by state — always confirm the current rate on your state's registration/IGR portal rather than relying on a quoted figure.
• Get every clarification from the developer in writing, and keep a dated record of what you found and what you asked.
• Never assume a brochure's descriptions are legally binding — only the BBA's actual clauses are.
• Present facts, sources, and as-of dates to yourself and to the developer — never rely on a verbal assurance for anything financially significant.
• DrawMagic's buyer workspace at /buyer/dream-home is a private place to build your own due-diligence record, not a broker or legal advisor.

FAQ

Is a builder legally required to register the Agreement for Sale once I've paid 10%? Several states require registration of the Agreement for Sale once a specified payment threshold, commonly cited as 10% of the total price, has been paid — but confirm the exact rule and timeline for your state directly on the relevant RERA portal or with a licensed lawyer, since implementation details vary.

What should I do if the possession date in my BBA doesn't match the RERA-declared date? Raise it with the developer in writing and ask for a clear explanation before you sign. This is a factual discrepancy worth resolving on paper, not something to assume is a simple oversight.
