A Mulund buyer in June 2026 was handed a 90 page agreement for sale and told, with a smile, that it was standard and there was no point reading it. Buried inside was a clause letting the builder change the possession date at will, exactly the kind of one-sided term that Maharashtra's rules say cannot override the model agreement. Buyers who know the model agreement exists read that 90 page document very differently. This piece is written to make you one of them.

The short answer. Maharashtra's RERA rules prescribe a Model Form of Agreement for Sale, set out as Annexure A under Rule 10, and the clauses in it that flow from the statute are mandatory and must be retained in every agreement between a builder and a buyer. A promoter can propose extra terms, but any deviation has to be highlighted in a different colour when the agreement is uploaded at project registration, and if a deviation contradicts the Act or the rules, the registration application is liable to be rejected. The trade-off for a Mumbai buyer is that the protection only works if you use it. The model gives you a benchmark to measure the builder's draft against, but nobody at the sales desk will point out where their version departs from it. You have to check. The official model agreement is published on the MahaRERA website.

This is a buyer-side guide. It explains what the model agreement is, which clauses cannot be watered down, how to spot a builder's deviations, and the honest limits of the protection.

What is the MahaRERA model agreement for sale?

The model agreement for sale is a standard template prescribed under Maharashtra's real estate rules, published as Annexure A and tied to Rule 10, that sets out how the contract between a promoter and an allottee should read. It exists precisely because agreements were historically drafted by builders entirely in their own favour. By fixing a model with mandatory clauses, the rules give every Maharashtra buyer a common floor of protection that a private draft cannot legally sink below.

The important word is mandatory. The clauses in the model that come directly from the statute, covering things like the possession date, interest on delay, the carpet area basis and the defect liability period, are non-negotiable and have to appear in your agreement. A builder cannot quietly drop them, and a buyer should treat their absence as a red flag rather than an oversight.

Which clauses can a builder not dilute?

The non-negotiable clauses are the ones that carry the statute's buyer protections into your specific contract. The committed date of possession must be stated, and the consequence of missing it, interest to the buyer for the delay, cannot be written away. Pricing must be on the RERA carpet area, the net usable floor area, rather than a larger built up or super built up figure that inflates the rate. The builder's obligation to rectify defects within the statutory defect liability period, five years under RERA, has to be present. And the payment schedule must be tied to stages of construction rather than front loaded arbitrarily.

If a builder's draft weakens any of these, for example by making the possession date indicative only, or by pricing on super built up area, or by cutting the defect liability short, that is a deviation from the mandatory model and you are entitled to push back on it. The model agreement is your evidence that the term is not, in fact, standard.

How are a builder's deviations supposed to be flagged?

The rules do not leave deviations to chance. When a promoter proposes any modification to the model agreement, that change is required to be highlighted in a different colour in the document uploaded for the project's registration, so it is visible rather than hidden in dense text. If the highlighted deviation is contrary to the Act, the rules or the regulations, the promoter's registration application is liable to be rejected. In other words, the system is designed so that departures from the model are conspicuous and reviewable.

For a buyer, this creates a practical checkpoint. The version of the agreement associated with the registered project should make deviations visible, so comparing the builder's draft handed to you against both the model and the registered version is a powerful way to catch a term that should not be there. If a change is not flagged where it should be, that itself is worth questioning.

How should a Mumbai buyer read the agreement?

Reading a long agreement is tedious, but you do not have to read it blind. Anchor your reading to the mandatory clauses and check each one against the model, rather than trying to absorb every paragraph equally. The goal is not to become a lawyer overnight but to confirm that the protections the statute gives you have survived into your specific contract.

1. Download the official model agreement for sale from the MahaRERA website as your benchmark.
2. Locate the possession date clause and confirm it states a firm date, not an indicative one.
3. Check that interest for delayed possession is retained at the statutory rate.
4. Confirm the price is on RERA carpet area, not built up or super built up area.
5. Verify the defect liability clause keeps the full five year period.
6. Check the payment schedule is linked to construction stages.
7. Flag any clause that departs from the model and get it explained in writing before signing.

Verification of the project and the agreement go hand in hand, so first confirm the project itself on the portal using our guide to the MahaRERA MahaCRITI platform. And because the agreement has to be stamped and registered, budget that cost using our breakdown of Maharashtra stamp duty and registration.

What if the builder refuses to change a clause?

A builder may insist a diluted clause is non negotiable. Here the model agreement shifts the conversation from opinion to rule. If the clause in question is one of the mandatory, statute derived terms, the builder is not entitled to weaken it, and you can point to the model as the standard the agreement is meant to follow. If the builder still refuses, that refusal is itself information about how the developer treats buyers, and it is far better to learn it before you pay than after.

The honest trade-off is leverage. In a hot launch a single buyer has limited power to force a change, and walking away has a real cost if you love the home. But knowing which clauses are mandatory lets you focus your negotiation on the terms that actually matter, rather than spending goodwill on trivia, and it lets you make an informed choice if a builder will not comply.

What are the honest limits of the model agreement?

The model agreement protects the structure of the deal, but it is not a substitute for the rest of your diligence. It does not verify the builder's title to the land, confirm the approvals, or guarantee construction quality. A perfectly compliant agreement with a developer who cannot deliver is still a problem. Treat the model agreement check as one essential layer, sitting alongside a title and approvals review, a look at the developer's delivered projects, and independent legal advice on the final draft. Used that way, it closes off one of the most common ways buyers get hurt, a one-sided contract they signed without realising the law was on their side. It is worth being clear about what a compliant agreement does and does not buy you. It guarantees that the rules of the game are fair, not that the developer will play well or finish on time. Two buyers can hold equally compliant agreements and have very different experiences depending on the builder behind them. So use the model to win the contract fight, then keep your attention on the developer's track record, financing and approvals, because those decide whether the fair contract ever has to be enforced at all.

Is the model agreement for sale mandatory in Maharashtra?

The model form is prescribed under Maharashtra's rules as Annexure A to Rule 10, and the clauses in it that flow from the statute are mandatory in every agreement between a builder and a buyer. A promoter may add extra terms, but the statutory clauses cannot be diluted or dropped, so treat a missing one as a warning.

Can a Mumbai builder change clauses in the agreement?

A builder may propose modifications, but any deviation must be highlighted in a different colour when the agreement is uploaded at project registration. If a deviation is contrary to the Act, the rules or the regulations, the registration application is liable to be rejected. Mandatory statutory clauses cannot be weakened, so compare the draft against the model.

What should carpet area pricing look like in the agreement?

Price should be stated on the RERA carpet area, the net usable floor area of the flat, not on a larger built up or super built up figure. If the agreement prices on super built up area, you effectively pay for space you cannot use. Confirm the carpet area basis against the model agreement before signing.

Where do I find the official MahaRERA model agreement?

The model form of agreement for sale is published on the MahaRERA website as Annexure A under Rule 10. Download it and use it as your benchmark, checking the possession date, delay interest, carpet area pricing, defect liability and payment schedule in the builder's draft against the mandatory clauses in the model before you sign.
