Brochure Area vs RERA Area: Which One Decides What You Own?

Summary (2026)

Bottom line: the papers you sign and register define your purchase, not the brochure. First comes the Agreement for Sale and later the Sale Deed. When the brochure and the RERA filing differ, the filing wins. The promoter swears to it before the regulator against the sanctioned plan, and Section 89, which gives the Real Estate (Regulation and Development) Act 2016 overriding force, backs it. That does not make the brochure useless to you. Section 12, a buyer who paid an advance trusting a false or incorrect statement in an advertisement or prospectus can seek compensation, or can withdraw and take back the whole amount with interest. Still, a brochure never enlarges what the RERA-registered project and your own agreement give you. Often there is no real discrepancy, since brochures quote super built-up area and the RERA filing must show carpet area (Section 2(k)). So reconcile the figures before you sign, and have your Agreement for Sale record the RERA carpet area in writing. Test any land-extent claim against the sanctioned layout and the land's title chain, not against the brochure.

Which document settles what you are buying?

Three documents are involved, and their legal weight differs greatly.

Start with the brochure, which is an advertisement made to sell. RERA takes the same view. Under Section 11(2), the RERA registration number and the authority's website must be shown prominently in every advertisement and prospectus, so that the buyer can go beyond the sales copy to the registered details. MahaRERA enforces the rule hard. Under its Order No. 46/2023 dated 29 May 2023, all project advertisements published from 1 August 2023, brochures included, must show the project QR code with the registration number and the authority's website. Non-compliant promoters are penalised, as in Suo Motu Advertisement Case No. 43 of 2024 (order of 3 April 2024). The point is to send the buyer to the registered record, away from the marketing copy. A brochure cannot create ownership or draw a boundary. Its one legal consequence is against the builder, under Section 12.

Next is the RERA filing, which is the promoter's statement about the project to the regulator. Registration requires declarations under Section 4, among them an affidavit that the promoter holds legal title to the land (Section 4(2)(l)(A)). The promoter also discloses the sanctioned plan, the layout and apartment carpet areas. This is the sworn, authoritative account of the project. It guarantees no title, yet the promoter swore to it before the regulator, and every other document has to agree with it.

The Agreement for Sale, once registered, is the third document and the contract that binds you personally. It covers your apartment, its carpet area, your share in common areas, the price and the delivery date. Under Section 13 a promoter may not take more than ten per cent of the cost as an advance before a written, registered Agreement for Sale exists, which tells you that your money is tied to the agreement and not to a brochure or allotment letter. The Sale Deed that follows conveys the property. What passes to you is set out in its Schedule, with boundaries and extent.

The order of rank is therefore clear before you open the brochure. What you buy is fixed by your registered agreement and deed. The RERA filing is the sworn reality of the project, backed by the sanctioned plan, and your agreement must match it. The brochure is a claim that can hold the builder to account in money, and gives no title.

Carpet area and super built-up area: the usual reason the figures differ

Before you suspect fraud, ask whether the two documents measure the same thing. Usually they do not.

RERA altered the unit in which flats are sold. The definition in Section 2(k) of carpet area is the net usable floor area inside an apartment. The thickness of external walls, service shafts, an exclusive balcony or verandah, and an exclusive open terrace do not count, but internal partition walls do. Flats must now be sold and priced on carpet area. Before RERA, marketing used super built-up area, which adds shares of lobbies, staircases, lift shafts and amenities to carpet area. It generally runs twenty-five to forty per cent above it.

So a glossy brochure printed to the older convention may say 1,450 square feet, while the RERA filing for the same flat says about 1,050 square feet of carpet area. Nothing has shrunk. The two figures measure one apartment in two different ways. It is neither a title problem nor, by itself, a breach of RERA. It is a mismatch of units that you must settle on paper. Ask for the carpet area in the RERA registration, check that your Agreement for Sale states that carpet-area figure and not a super built-up one, and read the quoted price as a rate per square foot of carpet area. If the builder resists writing the RERA carpet area into the agreement, take that resistance as the red flag, and not the brochure.

When the gap is real: land extent in the brochure against the sanctioned layout

A plot, a villa or a project can present a tougher case. The brochure may show a different quantity of land from the sanctioned layout that was filed with RERA. The gap can then be substantive.

If the brochure shows more land than the RERA filing, the extra may never have been included in the approved project. It might still belong to a joint-development landowner, lie outside the sanctioned layout, fall under a different approval, or be land the builder hopes to acquire. The approvals, common-area rights and amenities that the project is registered to deliver exist only inside the sanctioned layout. When the brochure's "extra" acreage lies outside it, your share of common areas and open space is computed on the smaller, sanctioned area. A clubhouse or park promised on the extra land may lack any approval. The sanctioned plan filed with RERA decides what may lawfully be built and shared. Section 14(2) allows a deviation from it only with the written consent of two-thirds of the allottees at the least, and this shows how firmly the sanctioned layout, rather than the brochure, is meant to hold.

Do not test it by setting two glossy numbers against each other. Obtain the sanctioned layout named in the RERA registration. Then compare its survey numbers and extent with the mother deed, the land's title chain and the revenue records. If the brochure's land and the sanctioned layout's land are not the same parcel, you must resolve it before you sign.

What RERA does about a false brochure

If the brochure misstated the area and you relied on it, RERA offers a remedy. It is a money remedy and does not rewrite your title.

Section 12 is the relevant provision. A person may pay an advance or deposit on the strength of a notice, advertisement, prospectus, model apartment or plot, and then suffer loss because of a false or incorrect statement in it. The promoter must compensate that person. If the person chooses to withdraw from the project for this reason, the whole investment comes back with interest and, where it applies, compensation. Where the promoter fails to deliver as agreed, Section 18 gives the wider right to a refund with interest, or to stay in the project and be paid interest for the delay. Section 14(2) protects the sanctioned plan against change without the allottees' consent.

Taken together, these provisions say something definite about your position. A false brochure does not quietly become part of your title, and it does not give you the larger area that it promised. What you get is compensation in money, up to the point of leaving the deal with your investment and interest returned. This is a real and useful lever. You pursue it before the RERA authority or the consumer forum, and it does not alter the sanctioned plan or the carpet area in your agreement.

Builders must deliver what they advertised, too. The National Consumer Disputes Redressal Commission said so in Nitin Agarwal v. Bombay Dyeing & Manufacturing Co., in its order of 12 July 2024. It held a developer to the brochure's promises and told the builder to cover the shortfall, in line with the Supreme Court ruling reported as (2020) 16 SCC 512 (Wg Cdr Arifur Rahman Khan v. DLF Southern Homes). A newer Supreme Court ruling, Parsvnath Developers v. Mohit Khirbat, 2026 INSC 170 (20 February 2026), deals with the compensation side. Clauses that favour the builder, it says, cannot curb a consumer forum's authority to award just and reasonable compensation for deficient service. So a brochure shortfall is a compensable wrong, and you are paid for it, but no extra title comes out of it.

Why the RERA filing outranks the brochure, while your registered agreement is what you sue on

Two rules lie behind the answer, and it helps to keep them apart.

First, Section 89 gives RERA overriding effect over anything inconsistent in any other law, and the Act's scheme makes advertising subordinate to the registered particulars. An unsworn brochure set against a sworn RERA filing backed by a sanctioned plan loses. The filing is the authoritative version of the project, and a brochure that contradicts it cannot win.

Second, what you enforce is your registered Agreement for Sale. A builder cannot use a brochure or an allotment letter to shrink the rights in your agreement, and the courts and the Act both say so. Relief for an area shortfall is not in one settled Supreme Court rule. You get it from the RERA authority or the consumer forum. Under MahaRERA's guidance and its model Agreement for Sale (clause 1(g)), the registered carpet area is the binding commitment, and when the delivered carpet area is smaller the promoter has to refund the proportionate excess and may not hide behind a tolerance clause. So your most useful move is to ignore the brochure in the dispute. See that the carpet area, common-area share and plot extent written in your Agreement for Sale are exactly those of the RERA filing, and see it before you pay past the ten per cent allowed by Section 13.

Boundaries beat extent: the title rule for the area of a plot

For a plot or other land, one more layer exists that most buyers never hear about, and it settles many disputes about area.

The Schedule of a Sale Deed describes land twice, once by extent (square feet, cents or acres) and once by boundaries (north, south, east and west). If they conflict, Indian courts have long preferred the boundaries, since boundaries identify the actual parcel while the extent is treated as approximate. The Supreme Court did the same in Ayyavu v. Prabha, 2025 INSC 336 (7 March 2025). It said the boundaries in a sale deed "play an important role" and allowed the buyer's claim by reading the deed's boundaries alongside the court commissioner's report and plan, though the extent sold differed from the vendor's original holding. In practical terms, neither a brochure's area nor a mismatch between the extent in the deed and a physical measurement is automatically a title defect. The boundaries in the Schedule, read with the survey sketch and the sanctioned layout, govern the land. The figure carries weight when boundaries are vague, when land was sold by measure at a rate, or when part of it is actually missing or encroached.

Why an encumbrance certificate will not show any of this

A clean encumbrance certificate misleads buyers quietly, because they go to it first. It is the result of a search, under the Registration Act 1908, of registered instruments for a survey number over a chosen period. Brochures, RERA filings and sanctioned plans are all unregistered, so no conflict between them can show on an encumbrance certificate. A spotless EC for the land therefore tells you nothing on whether the brochure area, the RERA carpet area and the sanctioned layout agree.

Other records answer the area question: the RERA registration and sanctioned plan on the state authority's portal, the carpet area stated in your Agreement for Sale, the extent and boundaries in the Schedule of the Sale Deed and the mother deed, and the revenue survey sketch. A brochure-versus-filing conflict is settled by reading these documents against one another, not by the EC that everyone downloads first.

Checks to run before you sign

Here is a short sequence to cut through the confusion.

Open the project's RERA registration on your state authority's portal, with the number that the brochure has to display. Read the registered particulars: sanctioned plan, layout, and the carpet area of your unit. Check that your Agreement for Sale gives the RERA carpet area, described as carpet area, and does not repeat a super built-up figure from the brochure. For a plot or the project land, set the survey numbers and extent of the sanctioned layout against the title chain and the mother deed. Hand over no more than ten per cent of the price before a written and registered Agreement for Sale exists. Section 13 requires this, and it also gives you leverage. Also keep the brochure. Should it have misstated the area and you relied on it, it is your proof for a Section 12 claim, even though it is no measure of your title.

Where LegiScore comes in

LegiScore is a technology provider, and it is neither a law firm nor a replacement for your own advocate. In this situation our title search reads the land's own records: the Schedule of the Sale Deed and the mother deed, the revenue survey records and the title chain. It shows where the recorded extent and boundaries disagree, before you pay. Setting the brochure against the RERA filing is something you do yourself, on the authority's portal, by the steps above.

If the figures for a property you are considering do not tally, get a title search report before you pay over the ten per cent the law permits.
