<p>You can file a RERA complaint for possession delays, structural defects within 5 years, undelivered amenities, unregistered projects, unauthorized plan changes, or unprocessed refunds. File Form M on your state's RERA portal (TN, Karnataka, or Telangana), paying a ₹1,000–5,000 fee. The adjudicating officer must decide within 60 days; relief can include 12% interest on delayed possession or a full refund with 12% interest.</p>
<p><strong>Quick answer:</strong> Filing a RERA complaint is a structured, time-bound process across Tamil Nadu, Karnataka and Telangana: gather your allotment letter, sale agreement, payment receipts and builder correspondence, optionally send a 30-day legal notice first, then register on the relevant state RERA portal (tnrera.in, rera.karnataka.gov.in, or rera.telangana.gov.in) and submit Form M with supporting documents and a ₹1,000–5,000 filing fee. The adjudicating officer is required to hear and decide the case within 60 days of filing. Available relief ranges from ordering the builder to hand over possession with 12% interest on the delay period, to a full refund with 12% interest if possession isn't possible, plus compensation for mental agony or alternate accommodation costs — and in extreme cases, suspension or deregistration of the project itself. If you're unsatisfied with the outcome, you can appeal to the RERA Appellate Tribunal within 60 days, and from there to the High Court.</p>
