Buying a home is one of the biggest investments in a person’s life — but what happens when the builder delays possession, changes the layout, or fails to deliver on promises?

This is where RERA (Real Estate Regulation and Development Act, 2016) becomes a powerful tool for homebuyers. The Maharashtra Real Estate Regulatory Authority (MahaRERA) allows buyers to file complaints online or offline against errant builders, ensuring faster resolution and legal protection.

In this guide, Advocate Malini Jain, an experienced RERA lawyer in Mumbai, explains the complete process of filing a complaint under RERA in Maharashtra and how professional legal assistance can make a major difference in your case.

When Can You File a RERA Complaint in Mumbai?

Under the RERA Act, a homebuyer can file a complaint if a builder or developer:

  • Delays possession or fails to hand over the property on time.

  • Fails to register the project with MahaRERA.

  • Makes false or misleading advertisements.

  • Changes the project plan or layout without consent.

  • Uses project funds for other purposes.

  • Refuses refund or compensation despite clear delays or defects.

These violations are common in Mumbai’s real estate market, making RERA an essential legal safeguard for both residential and commercial buyers.

Step-by-Step Process to File a RERA Complaint in Mumbai

Step 1: Gather Relevant Documents

Before filing your complaint, collect all necessary documentation:

  • Builder-buyer agreement or sale deed.

  • Payment receipts or transaction records.

  • Possession letter or communication from the builder.

  • Project registration number (available on MahaRERA website).

  • Any written communication (emails, letters, WhatsApp chats) proving your grievance.

Proper documentation strengthens your case during hearings.

Step 2: Visit the MahaRERA Official Website

Go to the official MahaRERA website (https://maharera.mahaonline.gov.in).
Here, you’ll find an option to register a complaint online.

  • Create your account by providing your name, email, and mobile number.

  • Once logged in, choose “Online Application – Complaint Registration.”

Step 3: Fill Out the Complaint Form

The complaint form will ask for details such as:

  • Project name and builder details.

  • Project registration number (if available).

  • Nature of complaint — delay, non-delivery, false advertising, etc.

  • Description of the issue (clearly explain the grievance).

  • Relief sought (refund, interest, possession, compensation).

Being specific and factual helps the authority understand the issue quickly.

Step 4: Pay the Filing Fee

A nominal fee of ₹5,000 is charged by MahaRERA for filing complaints.
This can be paid online through debit/credit card or net banking.

Once payment is complete, your complaint will be officially submitted, and you’ll receive a unique complaint number.

Step 5: Appear for Hearings

MahaRERA will schedule a hearing and notify both parties (homebuyer and builder).
During hearings:

  • Both parties can present their evidence and arguments.

  • The Authority examines the complaint, documents, and builder’s response.

  • Orders are usually passed within a few hearings.

Having a RERA advocate represent you ensures that your case is presented legally and persuasively.

Step 6: Enforcement of the RERA Order

If the Authority rules in your favor, the builder must comply with the order — which may include:

  • Payment of interest or compensation for delays.

  • Refund of the booking amount with interest.

  • Completion and timely possession of the project.
    Failure to comply with RERA orders can lead to penalties, fines, or imprisonment for the builder.
