How to File a MahaRERA Complaint Online: A Mumbai/Pune Buyer's Guide

Radhika bought a 2BHK in a Thane project three years ago. Possession was promised for December 2024. It is now mid-2026, the tower's twelfth floor is still bare concrete, and every call to the sales office ends with "another six months." She has an allotment letter, a registered agreement, and payment receipts for nearly the entire consideration — but no home. What she doesn't have, yet, is a MahaRERA complaint number.

If you are in Radhika's position — in Mumbai, Pune, Thane, Nagpur, or anywhere in Maharashtra — filing a complaint with the Maharashtra Real Estate Regulatory Authority (MahaRERA) is the direct, buyer-navigable route to a formal hearing, a possession or refund direction, and interest for the delay. This guide walks through exactly how to do it on the MahaRERA portal, what it costs, what documents you need, and where Mumbai and Pune buyers commonly go wrong.

What MahaRERA Is and Who Can File

The Real Estate (Regulation and Development) Act, 2016 (RERA Act) created a regulatory authority in every state; in Maharashtra, that authority is MahaRERA — widely considered India's most active state regulator by complaint volume, given the sheer scale of Mumbai Metropolitan Region (MMR) and Pune Metropolitan Region (PMR) construction activity. India's real estate sector is on a trajectory toward a US$1 trillion market by 2030 and already contributes about 7.3% of GDP, according to the IBEF Real Estate Industry in India report (February 2026) — and a regulator with real teeth is part of why the sector's credibility has improved over the past decade.

Under the RERA Act, a complaint can be filed by:

• An allottee (a buyer who has booked, agreed to purchase, or been allotted a unit) against a promoter (builder/developer) for delay, false advertisement, deviation from sanctioned plans, or failure to hand over documents.
• A promoter against an allottee (for example, for non-payment) — less common but legally available.
• A real estate agent, in certain circumstances.

Most first-time buyers filing in Mumbai or Pune are allottees complaining about possession delay, denial of interest for delay, mismatched carpet area, or a promoter's refusal to register the conveyance/society formation. Each of these is a distinct, well-trodden ground under MahaRERA's own complaint categories.

Step-by-Step: Filing on the MahaRERA Portal

Here is the practical sequence, based on how the MahaRERA online complaint module is structured as of this writing. Screens and menu labels can change — always follow the portal's current prompts.

1. Find your project's MahaRERA registration number. Every registered project has a unique MahaRERA number (format similar to P519xxxxxxxxx for MMR-registered projects). You'll find it in your allotment letter, agreement for sale, or the builder's marketing brochure/website (registered projects are legally required to display it). You can also search the project by name on the MahaRERA portal's public project-search page. You need this number to file — it is how MahaRERA identifies which promoter and project your complaint is against.
2. Register or log in on the MahaRERA portal. Go to maharera.maharashtra.gov.in and create a "Complainant" login using your mobile number and email if you don't already have one, or sign in if you do.
3. Navigate to the complaint filing section. Look for "File Complaint" or "Complaint against Promoter" under the online-services menu. Select the correct complaint type — most possession-delay cases fall under a complaint for compensation/interest under Section 18, or a direction for possession.
4. Fill in project and party details. Enter the MahaRERA registration number, promoter name, project name and location, and your own details as complainant (allottee).
5. State your relief sought. Be specific: for example, "possession with interest for delay under Section 18" or "refund with interest and compensation." Vague prayers slow down adjudication.
6. Upload supporting documents. The portal will prompt for scanned copies — see the checklist table below.
7. Pay the complaint fee online. MahaRERA complaint fees are commonly cited around ₹1,000 per complaint as prescribed under the Maharashtra RERA rules — confirm the exact current fee on the portal's fee schedule at the time you file, since fee structures are revised by notification from time to time.
8. Submit and note your complaint number. On successful submission, you'll receive an acknowledgment with a complaint/case number. Save this — it's your reference for every future step, including tracking hearing dates and, if needed later, execution of the order.
9. Track your case. Use "Complaint Status" or "Case Status" on the portal, entering your complaint number, to see hearing dates, orders, and case movement.

MMR and PMR: Why Maharashtra Sees So Many Filings

Mumbai Metropolitan Region and Pune Metropolitan Region between them account for a very large share of Maharashtra's registered RERA projects, given the density of high-rise residential construction across both regions. That density is also why delay-related complaints are common — large towers involve longer construction cycles, more approval dependencies (environmental clearance, fire NOC, occupation certificate), and more room for a single delayed approval to cascade into a possession slip of a year or more.

MahaRERA also runs a conciliation forum as an alternative, faster route before a full adjudicatory hearing. If you'd rather try a negotiated settlement — say, a revised possession date with a written interest commitment — you can request conciliation instead of, or sometimes alongside, filing a formal complaint. Conciliation is voluntary on both sides and doesn't have the binding force of an adjudicated order, but it's often faster and can resolve straightforward possession-delay disputes without a contested hearing.

Conciliation vs. Adjudication: Which Route Fits

Real-World Scenario: A Pune Buyer Files for Possession Delay

Consider a buyer in a Hinjewadi-adjacent project in Pune whose agreement promised possession in March 2024. By late 2025, the tower was still at slab stage on upper floors. The buyer gathered the registered agreement, three years of payment receipts, and a folder of unanswered emails to the builder's customer-care address. She searched the project name on the MahaRERA portal, found its registration number, and filed a complaint seeking possession with interest for delay under Section 18, uploading the same documents as evidence. Within a few weeks she received a hearing notice with a date, giving her a formal forum — instead of a call center queue — to press her case. This is illustrative of the process, not a claim about any specific builder, project, or guaranteed outcome; every case turns on its own facts and evidence.

Pro Tips

• File under the correct section. A possession-delay case is typically framed under Section 18 (refund/interest) or as a direction for possession with interest — get this framing right at filing, since it shapes the relief you can be granted.
• Keep a single, chronological PDF of correspondence. Adjudicating officers respond well to a clean, dated timeline rather than scattered screenshots.
• Don't wait for the "last" delay. If your possession date has already lapsed, you can file now — there's no requirement to wait for some further deterioration.
• Check for a project-wide complaint pattern. If other buyers in your project have filed, note their case numbers; a pattern of complaints can be relevant context, though each case is decided on its own record.
• Save your complaint number the moment you get it. You'll need it for every subsequent status check and, if the builder later ignores an order, for an execution filing.

Common Mistakes to Avoid

• Filing without the project's MahaRERA number. Search for it first — the complaint won't process correctly without it.
• Vague relief prayers. "I want justice" isn't actionable; state exactly what you want (possession by X date, refund with interest, compensation amount).
• Losing track of the original agreement or receipts. These are your primary evidence — keep certified/scanned copies in more than one place.
• Assuming the sales team's verbal assurances count as evidence. Only written correspondence and documents carry weight in a hearing.
• Missing hearing dates. Track your case status regularly on the portal once filed; non-appearance can delay or weaken your case.

How DrawMagic Fits Into Your Journey

Filing a MahaRERA complaint is a legal process that DrawMagic does not perform on your behalf and does not certify outcomes for.

Key Takeaways

• MahaRERA complaints can be filed entirely online at maharera.maharashtra.gov.in by any allottee against a registered promoter.
• You need the project's MahaRERA registration number, found on your allotment letter, agreement, or the portal's project search.
• Core documents: registered agreement or allotment letter, payment receipts, correspondence, ID proof, and the complaint fee (commonly cited near ₹1,000 — confirm the current fee on the portal).
• State your relief precisely — for example, possession with interest under Section 18, or refund with interest and compensation.
• MahaRERA's conciliation forum is a faster, voluntary alternative to a full adjudicated hearing for buyers who'd rather negotiate a settlement first.
• MMR and PMR account for a large share of Maharashtra's project registrations, and possession-delay complaints are correspondingly common there.
• Save your complaint number immediately — it's essential for tracking status and, if needed later, for execution of an order the builder ignores.
• DrawMagic organizes your project facts and timeline as an information tool; it does not file complaints, represent you legally, or guarantee any outcome.

FAQ

Do I need a lawyer to file a MahaRERA complaint? No — the portal is designed for buyers to file directly. Many buyers do engage an advocate for complex disputes or contested hearings, but it isn't a legal requirement to file.

What if I don't know my project's MahaRERA registration number? Search the project by name and location on the MahaRERA portal's public project-search tool, or check your allotment letter/agreement, which are required to display it.

Can I file if my agreement isn't registered yet? You may still be able to file using an allotment letter and payment receipts as evidence of the booking, but a registered agreement is stronger evidence — confirm the specific requirement on the portal or with a professional.

What happens after I submit the complaint? You'll receive a complaint number and, in due course, a hearing notice. Track progress under "Complaint Status" on the portal using that number.
