Someone just showed you a beautiful 2 BHK in Goregaon. The sample flat looks good. The builder seems confident. The broker says three other buyers are interested.
Then they ask for a booking amount.
Before you transfer a single rupee, there is one thing you need to do. It takes five minutes. It costs nothing. And it has protected thousands of Mumbai buyers from paying crores for projects that had no legal right to take their money in the first place.
Check the MahaRERA registration.
This guide tells you exactly how — step by step, using a live Goregaon project as the walkthrough example — and what to do if the check reveals something you weren’t expecting.
The escrow account requirement is the most financially significant protection.
Before RERA, builders routinely used money collected from buyers in Project A to fund construction in Project B. Buyers had no legal mechanism to stop this — and thousands lost crores when projects stalled mid-construction. The escrow rule ring-fences your payment to your specific project.
Without RERA registration, none of these protections apply. You are simply an unsecured creditor with a booking receipt.

If a builder tells you their project is “small” or “exempt” and cannot produce a RERA registration number, verify that claim on the portal yourself before proceeding.
A project that genuinely qualifies for exemption will have a clear explanation. A builder who deflects or pressures you to trust them instead of checking is giving you the most important signal the due diligence process can produce.

Do not rely on links sent by the builder or broker — always type the URL directly into your browser.
The search works across all three identifiers: the project name, the developer’s name, or the RERA registration number itself. If you have already been given a RERA number, searching by that is the fastest verification. If you have only the project name, use that — and verify that the developer name in the results matches the builder you are dealing with.

Finding the project on the portal is step one. Reading the details page correctly is where the real due diligence happens.
Every one of these six checks takes under two minutes on the portal. Together, they tell you whether the project is legally compliant, whether the builder has a clean track record, and whether what you’re being told in the sales office matches what the government has on record.
Let’s run the actual check on one of the most actively discussed new projects in Goregaon East — Origin Claremont in Gokuldham Colony.
Step 1: Go to maharera.maharashtra.gov.in. Switch to English.
Step 2: Click “Home Buyers” → “Registered Projects.”
Step 3: In the search box, type “Agarwal Oak” or “RERA Registration Number” and Press Search.
Step 4: The results show the matching project. Click the project name to open the details page.
What you verify on the details page:
The RERA registration number appears in the format P51900XXXXXX — the “P” denotes Project, “51900” is Maharashtra’s state code, followed by a unique 6-digit identifier. Always ask the developer or agent for this number before signing any booking form — a legitimate builder will have it immediately available. Houssed
You then cross-check five things:
Does the developer name on the portal match the entity you’re signing with? Does the registered carpet area for a 3 BHK match the 1,216 sq ft figure the sales team quoted? Is the possession date aligned with what the broker told you? Is the registration status Active? Does the builder’s compliance history show a clean record on previous projects?
If all five match — proceed to the next stage of your due diligence. If any one doesn’t match — ask the builder for a written explanation before proceeding. Not a verbal reassurance. A written explanation.

A lapsed registration is not automatically fatal — builders can apply for renewal and continue legally after renewal is granted. But a lapsed registration that has not been renewed means the builder is selling without current legal authority.
Buying in such a project removes your RERA protections entirely. Any money you’ve paid becomes an unsecured claim rather than a protected escrow deposit.

Most reputable brokers in Goregaon are RERA registered and will provide their number without hesitation.
If a broker becomes evasive when you ask for their registration number, that evasiveness is its own form of due diligence result.

Valid grounds for a MahaRERA complaint include: possession delayed beyond the registered date, carpet area delivered is less than RERA-registered area, promised amenities not delivered, money collected before RERA registration, and structural defects reported within 5 years of possession.
MahaRERA also maintains a Conciliation Forum — a faster, less adversarial route for disputes where both parties are willing to negotiate. On the first date of hearing, if both parties consent, the complaint may be transferred to the Conciliation Forum. Keystonerealestateadvisory
The Conciliation Forum route resolves disputes significantly faster than the formal adjudication process and is worth requesting if the builder is cooperative.

The MahaRERA check is the single most powerful five-minute action available to any property buyer in Maharashtra.
It is free. It is public. It reveals the builder’s legal authority to sell, their compliance history, the registered carpet area, and the committed possession date — all before you pay anything.
Everything else in property due diligence — the society visit, the home loan, the stamp duty calculation — comes after this step. Not before.
If the builder is legitimate, the check will confirm it in seconds. If they’re not, five minutes on the portal will save you from a mistake that takes years and lakhs to undo.
Guides that go alongside this one — for buyers doing their complete due diligence before committing:
A MahaRERA registration number follows the format P51900XXXXXX for projects in Mumbai. The “P” stands for Project, “51900” is Maharashtra’s state code, followed by a unique 6-digit identifier. Always ask the developer or agent for this number before signing any booking form or paying any amount. If they cannot provide it immediately, either the project is not yet registered or the registration is not currently active. Houssed
Yes. Under the Real Estate (Regulation and Development) Act 2016, all residential and commercial projects above 500 sq mt of land or with more than 8 apartments must be registered with MahaRERA before any marketing or sales activity. This applies to every new and under-construction project in Mumbai, including Goregaon, Malad, Kandivali, and all other suburbs. Projects that are fully completed with an Occupancy Certificate are exempt from active registration but their historical compliance can still be verified. Houssed
You lose all RERA protections — the escrow fund protection, the legally enforceable possession date, the carpet area guarantee, and the grievance redressal mechanism. Your only legal recourse becomes civil court, which is slower and significantly more expensive than MahaRERA proceedings. Any advance payment collected before MahaRERA registration is explicitly illegal under the Act. If this has already happened to you, consult a property lawyer immediately. IndexTap
Yes — click on “View Details” on any project’s registration page to check the developer’s full history, including penalties received, delays on previous projects, and whether any earlier registrations have lapsed or been revoked. A builder with multiple lapsed registrations on older projects is a material risk signal for any new project they are currently selling. This check takes under two minutes and is one of the most valuable steps in the process. Business News Week
A lapsed registration means the builder did not renew their registration after the possession deadline passed — it could be administrative failure or a sign of project distress. A revoked registration means MahaRERA has actively cancelled the project’s registration — typically for serious non-compliance or fraud. Both statuses are listed in dedicated sections on the MahaRERA portal under the Registration tab. A revoked registration is more serious — it means regulatory action has already been taken against this specific project or builder. Quora
The filing fee for a complaint against a builder in Maharashtra is ₹5,000, payable via NEFT, RTGS, or digital transaction mode. If you are not satisfied with MahaRERA’s decision, you can appeal to the RERA Appellate Tribunal within 60 days, and further to the High Court within 60 days of the Tribunal’s decision. A MahaRERA Conciliation Forum option is also available for faster resolution if both parties agree to negotiate. Avalon Residency
Valid grounds include: possession delayed beyond the registered date, actual carpet area delivered is less than the registered area, promised amenities not delivered, money collected before RERA registration, structural defects within 5 years of possession, false promises in advertisements or brochures, excessive charges beyond the agreed price, and non-disclosure of important project details. If found in violation, a builder can face a fine of up to 10% of the project cost. Navimumbaihouses | Avalon Residency
On the MahaRERA portal at maharera.maharashtra.gov.in, click “Search Agent Registration” and enter the agent’s name or registration number. An unregistered agent cannot legally facilitate property transactions in Maharashtra. Always ask your broker for their MahaRERA agent registration number at the first meeting — before they show you any properties. A legitimate, professional broker will provide it without hesitation. Houssed
The MahaRERA Conciliation Forum is a faster, less adversarial dispute resolution route available when both buyer and builder agree to negotiate. On the first date of a formal complaint hearing, if both parties consent, the complaint can be transferred to the Conciliation Forum. For disputes where the builder is willing to engage constructively — such as possession delays rather than outright fraud — the Conciliation Forum typically resolves matters faster than formal adjudication. It is worth requesting at the first hearing if the builder is cooperative. Keystonerealestateadvisory
Not directly — completed buildings with an Occupancy Certificate are exempt from active RERA registration. The original RERA protections during construction no longer apply to a completed building. For resale transactions, your protection comes from the registered sale deed, Occupancy Certificate verification, clear title check, and society NOC. You can still verify the building’s original RERA registration history on the portal to check whether the original project was compliant — but the formal protections are those of property law and civil court, not RERA’s grievance mechanism.
No — “RERA applied” means only that an application has been submitted. It provides no legal protection whatsoever. Only an active, confirmed registration number visible on the MahaRERA portal constitutes legal RERA registration. Do not pay any booking amount, token money, or advance until the registration number is live and verifiable on the portal. The words “RERA applied” from a builder are not a substitute for an actual registration number. IndexTap
Under RERA, developers must deposit 70% of all funds collected from buyers into a dedicated escrow account for that specific project. The money in this account can only be used for construction and land costs for your project — it cannot be transferred to another project or used for the developer’s general expenses. This directly prevents the pre-RERA practice of builders using money from Project A buyers to fund Project B construction. The escrow rule is monitored by MahaRERA and is one of the most financially significant protections the Act provides to buyers. Houssed
