How to file a complaint against a builder on MahaRERA — steps, fee and timeline

Updated 5 October 2026 · Based on the RERA Act 2016 and MahaRERA’s rules · General information, not legal advice

Short answer

Create a complainant account on MahaRERA's online portal, fill in the complaint form (Form A) with your project, flat, payments and dates, upload your documents and pay the fee — MahaRERA states it as ₹5,000 plus applicable charges for an individual complaint — then submit. You can also choose MahaRERA's conciliation forum to settle with the builder through a neutral mediator. Complaints are heard in order of filing.

Before you file

The project must be registered with MahaRERA (there's a separate route for unregistered projects).
Write to the builder first and keep the reply — it shows you tried to resolve it.
Decide what you're asking for: interest for delay, a refund with interest, possession, correction of a defect, or something else under the Act.
Choose one forum: MahaRERA's FAQ says you can approach either MahaRERA or the consumer forum for the same grievance, not both.

Step by step

Go to MahaRERA's online application portal and create a complainant profile.
When registering, MahaRERA offers its Conciliation Forum. Choose 'Yes' to try a mediated settlement first, or 'No' to go straight to a complaint.
Fill in the complaint form (Form A): your building and flat number, the builder's details, the price, the amount you've paid, and the allotment, agreement and possession dates.
Upload your documents — the agreement for sale, payment receipts, correspondence and photos. MahaRERA asks for a convenience set of no more than 20 pages.
Pay the fee (₹5,000 plus applicable charges for an individual complaint, as MahaRERA's FAQ states) and submit.

After you file

MahaRERA checks the complaint and lists it for hearing in order of seniority.
If both sides agree to settle on the first hearing date, the complaint can be sent to the conciliation forum.
A claim for compensation (as opposed to interest or a refund) is decided by the Adjudicating Officer.
If you disagree with the order, you can ask for a review within 45 days, or appeal to the Maharashtra Real Estate Appellate Tribunal within 60 days (appeal fee ₹5,000).
If the builder doesn't follow the order, you can file a non-execution application after 60 days from the order — MahaRERA charges no fee for this.

How GharKundli helps

Common questions

Can several buyers of the same project complain together?

Each buyer has their own agreement and payments, so each usually files their own complaint — but filing together, with the same facts and evidence, is common and makes the pattern hard to ignore.

Do I need a lawyer?

The online form can be filled in yourself, but a lawyer experienced in RERA matters helps you ask for the right relief and present the evidence. Several buyers often share one lawyer.

Is there a time limit for MahaRERA to decide?

MahaRERA's FAQ says no time limit is prescribed for deciding complaints on merits; compensation applications have a 60-day period under Section 71(2).
