RERA Agreement for Sale: Clauses Buyers Must Read

The sales executive slides a stack of pages across the table, flags a handful of spots with yellow sticky tabs, and says, "just sign here, here, and here — it's the standard agreement, everyone signs the same thing." You've waited months for this apartment, the loan is sanctioned, and the pressure to just get it done is real. But the document in front of you — the Agreement for Sale — is not paperwork to rush through. It is the single legal instrument that will define your possession date, your carpet area, what happens if the builder is late, and what happens if you are. Under India's Real Estate (Regulation and Development) Act, 2016, a meaningful chunk of what's inside that document isn't actually negotiable at the builder's discretion — it's mandated.

This article walks through what RERA requires to be in your Agreement for Sale, what a fair version of each clause looks like, and which common wordings should make you pause and ask questions before you sign. DrawMagic is not a law firm and this is not a substitute for a lawyer reviewing your specific agreement — treat this as the map that helps you have a sharper conversation with one.

Why the Agreement for Sale Is Your Core RERA Protection

Before RERA, builder-buyer agreements in many Indian cities were drafted almost entirely in the builder's favor — vague possession timelines, one-sided penalty clauses, and carpet-area definitions that could shift after the fact. RERA changed the starting point by requiring, under Section 13, that a promoter cannot accept more than 10% of the property's cost as an advance or application fee without first entering into a written, registered Agreement for Sale. That single rule forces the agreement to exist — and to exist early — before serious money changes hands, which is why several states have gone further and prescribed a model Agreement for Sale (Maharashtra's is a well-known example) fixing the mandatory particulars every builder must include, regardless of how the builder's own legal team might prefer to word things.

The result is that your Agreement for Sale is not just a sales contract; it is the document through which several of RERA's buyer protections become legally enforceable in your specific transaction. Reading it carefully, and understanding which clauses are non-negotiable by law, is one of the highest-leverage forty-five minutes you'll spend in the entire home-buying process.

Clause-by-Clause: The Mandatory Particulars

1. Project and unit identification. The agreement must specify the RERA registration number of the project, the specific unit/flat number, floor, and its precise description — this ties your individual purchase to the registered project record.
2. Carpet area, as defined by RERA (Section 2(k)). The agreement must state the carpet area in the RERA-defined sense — the net usable floor area within the walls, excluding balconies, common areas, and external wall thickness — not a loosely defined "super built-up area."
3. Total sale consideration and payment schedule. The price and the stage-wise payment schedule must be tied to actual construction milestones, not arbitrary calendar dates disconnected from progress on site.
4. Date of possession. A specific, committed possession date must be stated — this is the anchor for delay-interest calculations if the builder misses it.
5. Interest for delay — payable by either party. RERA rules require that the interest rate for delay is meant to apply symmetrically: if the builder is late handing over possession, the builder owes interest to the buyer; if the buyer is late in installments, the buyer owes interest to the builder, typically at the same rate.
6. Specifications, amenities, and common areas. What's promised — fittings, finishes, clubhouse, parking, and common facilities — must be specified, giving you something concrete to hold the builder to at handover.
7. Right to cancel/withdraw and refund terms. The agreement must set out the buyer's right to withdraw from the project (with refund and interest) in specified circumstances, such as material changes to the plan or persistent delay.
8. Defect-liability clause. RERA imposes a statutory defect-liability period (structural and other defects reported within a set period after possession must be rectified by the promoter without extra charge) — your agreement should reflect this obligation rather than water it down.
9. Formation of the association of allottees and conveyance of title. The builder's obligation to facilitate formation of the owners' association and eventually convey title/common areas should be stated, tying back to RERA's requirements on this front.

Clause vs Requirement vs Red Flag: A Quick-Reference Table

Model Agreements, Carpet Area, and Delay Interest — the Local Detail That Matters

Several states have issued their own model Agreement for Sale under their RERA rules, and Maharashtra's is one of the most frequently referenced — it standardizes formatting and mandatory particulars so a builder can't quietly drop a clause the state rules require. If you're buying in Maharashtra, ask specifically whether the agreement you've been given tracks the state's model form; if you're elsewhere, ask your state RERA portal or a local lawyer whether a model agreement applies in your state and, if so, whether your draft conforms to it.

Carpet area deserves special emphasis because it was one of the most common pre-RERA pain points, particularly in dense markets like Mumbai, Bengaluru, and Delhi-NCR, where "super built-up area" pricing could quietly inflate the effective per-square-foot cost well beyond the space you actually got to use. RERA's carpet-area definition exists specifically to give buyers a comparable, honest number across projects and builders — if your agreement states only a built-up or super-built-up figure without also giving you the RERA carpet-area number, that's worth raising before you sign.

Delay interest is the other detail buyers often skim past. State rules typically benchmark the delay-interest rate to a reference rate such as SBI's marginal cost of funds-based lending rate (MCLR) plus a margin, and — critically — that rate is meant to apply in both directions. If your draft agreement charges you a steep penalty for late installments but offers a token or undefined rate for the builder's own delay, that asymmetry runs against the spirit (and often the letter) of the applicable state rules.

A Real-World Scenario: A Bengaluru Buyer Spots a One-Sided Clause

A buyer in Bengaluru, close to signing on a two-bedroom unit in an under-construction project, notices that the delay-interest clause specifies 2% per month if she's late on any installment, but the corresponding clause for the builder's possession delay simply reads "interest as applicable under RERA rules" without naming a rate or a calculation method. She raises it with the builder's sales team, who initially call it "standard language." When she asks her lawyer to compare the clause against the state's model agreement and RERA rules, the lawyer confirms the builder-side rate should be explicitly stated and symmetrical to the buyer-side rate. The builder's legal team ultimately amends the clause before signing — a change that would have been far harder to negotiate after the fact, once money had already changed hands.

Carpet Area vs Super-Built-Up Area, Explained Simply

Carpet area is the actual usable floor space inside your unit's walls — the area you could, in principle, cover wall-to-wall with carpet. Built-up area adds the thickness of your unit's own walls and any balcony or utility area. Super-built-up area (sometimes called "saleable area") goes further, adding a proportional share of common areas — lobbies, staircases, corridors, and shared amenities — spread across all units in the project. RERA mandates disclosure and use of carpet area specifically because it's the one figure that can't be inflated by a generous allocation of "common area" on paper; comparing carpet area across two projects tells you, more reliably than comparing super-built-up figures, how much actual living space you're paying for.

Pro Tips Before You Sign

• Insist on the registered Agreement for Sale before making any payment beyond the 10% cap — a builder asking for more before registration is stepping outside RERA's own rule.
• Cross-check the RERA registration number on the agreement against the project's live listing on your State RERA portal — the numbers, promoter name, and project details should match exactly.
• Ask for the carpet-area figure explicitly, not just a super-built-up number, and get it in writing in the agreement itself, not a separate brochure.
• Read the delay-interest clause both directions — confirm the builder's rate for late possession is symmetrical to your rate for late payment, or at least reasonably comparable under your state's rules.
• Never leave annexures — specifications, floor plans, payment schedules — blank at signing; get them fully filled in and initial each page.

Common Mistakes to Avoid

• Signing blank or "to be filled later" annexures, trusting the builder to complete them faithfully afterward.
• Ignoring the exact possession date and accepting vague qualifiers like "approximately" or overly broad force-majeure carve-outs that could stretch the timeline indefinitely.
• Treating carpet area and super-built-up area as interchangeable when comparing this project to another, or when calculating your effective cost per square foot.
• Paying more than 10% before the agreement is registered, under pressure to "lock the price" or beat a rate hike.
• Assuming "standard language" means "state-mandated language" — some clauses genuinely are standard and lawful; others are simply boilerplate the builder's legal team prefers, and only a comparison against your state's rules or model agreement tells the difference.

How DrawMagic Fits In

DrawMagic does not draft, review, or certify Agreements for Sale — that is squarely a lawyer's job, and we'd rather say that plainly than blur the line. What the evolving Buyer Intelligence workspace is designed to help with is cross-checking the project details stated in your agreement — RERA registration number, promoter name, project status — against the publicly available RERA-registration facts, so you walk into your lawyer's review already knowing whether the paperwork matches the public record.

If you want to talk through which clauses felt off while reading your draft agreement, the private, voice-first companion at DrawMagic for buyers can help you organize your questions before that conversation with counsel.

A Value Note, Plainly Stated

Clause-by-clause review of a legal document is a legal task. DrawMagic organizes the public, factual side of the picture — registration status, project details — and helps you prepare sharper questions; it does not replace a lawyer vetting your specific Agreement for Sale, and it never rates, certifies, or guarantees any builder or project.

Key Takeaways

• Section 13 of the RERA Act bars a builder from taking more than 10% of the unit's cost before a written, registered Agreement for Sale exists.
• Several states prescribe a model Agreement for Sale fixing mandatory particulars — check whether one applies where you're buying.
• Carpet area, as defined under RERA Section 2(k), must be stated explicitly and is the fairest basis for comparing space across projects, unlike super-built-up area.
• The possession date must be specific, and delay-interest clauses should apply symmetrically to builder delay and buyer delay.
• Payment schedules should be tied to actual construction milestones, not arbitrary calendar dates.
• A statutory defect-liability period applies post-possession — your agreement shouldn't water this down.
• Never sign an agreement with blank annexures for specifications, floor plans, or payment schedules.
• Cross-check the agreement's RERA registration number against the project's live listing on your State RERA portal.
• Have a lawyer review the final agreement before signing, especially the delay-interest, cancellation/refund, and defect-liability clauses.
• DrawMagic's Buyer Intelligence workspace helps verify public project facts against your agreement; it does not provide legal review.

FAQ

Is the model Agreement for Sale mandatory in every state? Not every state has issued its own model agreement; several have, including Maharashtra. Check your state's RERA rules or ask a local lawyer whether a model form applies to your purchase.

Can a builder still ask for more than 10% before the agreement is registered? Under Section 13 of the RERA Act, a promoter should not accept more than 10% of the cost as an advance or application fee before entering into a registered Agreement for Sale. If you're being asked for more, raise it and consult a lawyer before paying.

What if the delay-interest rate in my agreement isn't symmetrical? Flag it before you sign. State rules generally intend the rate to apply comparably in both directions; an asymmetrical clause is a common area builders are willing to amend when a buyer raises it early, before the agreement is finalized.

Does the Agreement for Sale replace the final sale deed? No. The Agreement for Sale governs the construction and delivery phase; the sale deed (conveyance) is the separate, later document that transfers ownership title once possession and registration formalities are complete.
