If a builder in Karnataka delays possession, deviates from the sanctioned plan, or misrepresents a project, the Karnataka Real Estate Regulatory Authority (K-RERA) is where you file a formal complaint — not a court, and not the builder’s own customer service. Here’s the actual process.
Step 1: Confirm the project is RERA-registered
Go to rera.karnataka.gov.in Project Search, and look up the project by name or RERA registration number. Confirm the registration is active (not lapsed) and note the registered possession date — this is your baseline evidence if your complaint is about a delay. Take a screenshot with the date visible.
Step 2: Gather your documents before you start the form
Have these ready as PDFs before you begin, so you’re not scrambling mid-form:
- Registered sale agreement (or certified copy)
- All payment receipts and bank transfer records
- Written communication with the developer — emails, WhatsApp screenshots, letters
- The project’s RERA registration certificate
- Allotment letter and any demand letters from the developer
- Any possession-related correspondence
Step 3: Register on the portal and fill the complaint form
If you don’t already have an account, sign up on the K-RERA website with your email and mobile number. The complaint itself is filed as Form N (the standard complaint form under Karnataka RERA) via the portal’s complaint registration section. Fill in your details, describe the facts of your complaint clearly and specifically (dates, amounts, what was promised vs. what happened), and upload your supporting documents, clearly labeled.
Step 4: Pay the complaint fee
Sources differ on the exact current fee structure — some describe a flat 1,000 filing fee, others describe a tiered structure (roughly 1,000 for claims up to 10 lakh, 2,000 for 10-50 lakh, 5,000 above 50 lakh). Confirm the exact current fee directly on the portal at the time you file rather than relying on any article, including this one, since fee schedules can be revised. Pay online and upload the payment proof/challan as part of your submission.
Step 5: Submit and track
Once submitted, you’ll receive an acknowledgment with a unique complaint number — keep this, it’s how you track your case status on the portal going forward.
How long does it take?
Reported resolution timelines vary by source (some cite around 45 days, others around 60), and in practice actual timelines depend heavily on case complexity and current tribunal backlog. Treat any specific number as a rough expectation, not a guarantee.
If you’re an NRI
You can file and track complaints online through the K-RERA portal from abroad, and attend hearings via video conferencing. For steps that require physical document submission or in-person representation, it’s advisable to grant Power of Attorney to a resident representative in advance.
Do you need a lawyer?
Not mandatory — you can file and represent yourself. But if your case is complex (multiple violations, a large claim amount, or you expect the builder to appeal), legal guidance can meaningfully strengthen how the complaint is drafted and how an eventual appeal is handled.
