RERA complaint in Karnataka for delayed flat possession

If your builder has missed the possession date in your agreement, you can file a RERA complaint with the Karnataka Real Estate Regulatory Authority (K-RERA) on its website, rera.karnataka.gov.in. Under Section 18 of the Real Estate (Regulation and Development) Act, 2016, you choose between two remedies: leave the project and get your money back with interest, or stay and get interest for every month of delay until you are handed the flat.

The interest rate in Karnataka is fixed by the K-RERA Rules at the State Bank of India’s highest marginal cost of lending rate plus 2%. Getting an order is usually the easier part. Getting the builder to pay can take longer, and we explain why below.

Check the possession date in your registered agreement, not the date in the brochure.

Refund or delay interest: deciding first

Section 18(1) applies when the promoter fails to complete the project, or cannot give possession, by the date in the agreement for sale.

Under Rule 17 of the Karnataka RERA Rules, a refund with interest and compensation is to be paid by the promoter within 60 days of becoming due.

If the project is nearly done and the builder is still active, staying in with delay interest is often the practical choice. If construction has stopped for a long time, a refund order is easier to enforce than waiting for a flat that may never come.

Before you file: collect these

• the agreement for sale and the construction agreement, with the possession date and any grace period
• the allotment letter and all payment receipts, with bank statements showing the payments
• demand letters from the builder and any letters or emails about the delay
• the project’s K-RERA registration number and the completion date shown on the K-RERA website
• your home loan sanction letter and the tripartite agreement with the bank, if any

Read the agreement’s clauses on grace periods and force majeure before you file. Builders often argue that the delay was caused by events outside their control. Whether that holds depends on the facts and the wording.

Our apartment document checklist explains what each of these documents should show.

How to file the complaint on the K-RERA portal

1. Go to rera.karnataka.gov.in and register as a user, then log in to the complaint section.
2. Fill in the complaint form: your details, the promoter and project, the flat number, and the relief you want (refund with interest, or delay interest).
3. Upload the documents listed above as PDFs.
4. Pay the complaint fee online.
5. Note the complaint number. You will receive notices of hearing dates.

You can file it yourself. Many buyers do. A lawyer helps most in drafting the facts and the relief correctly, in countering the builder’s force majeure and grace period arguments, and in the recovery stage.

If several buyers in the same project face the same delay, each files a complaint, but you can coordinate through the apartment buyers’ association so the facts and documents are consistent.

What happens after filing

Under Rule 29 of the Karnataka RERA Rules, K-RERA follows a summary procedure:

• the builder gets a notice with the complaint and documents, and files a reply
• hearings are fixed, and K-RERA can call for more documents or evidence
• K-RERA passes an order, which may direct refund with interest, or delay interest, and can impose penalties

The time to an order varies with the number of cases and adjournments.

Compensation is a separate claim

Following the Supreme Court’s decision in Newtech Promoters and Developers v. State of UP (2021), refund and interest are ordered by the Authority, while compensation for loss, such as rent paid elsewhere or the cost of your loan, is decided by the Adjudicating Officer under Section 71. Claim it separately if your losses are more than the interest covers.

Getting the money: recovery certificates

If the builder does not pay after the order, K-RERA issues a recovery certificate under Section 40 of the Act and Rule 25 of the Karnataka Rules. The amount is then recovered as arrears of land revenue by the revenue authorities, not by K-RERA itself.

This stage has been slow in Karnataka, and many recovery certificates went unexecuted for long periods. In April 2026, in Rajesh Rao C.V. v. State of Karnataka, the High Court of Karnataka held that recovery certificates must be acted on by the designated authorities without delay and directed recovery within eight weeks in that case. A Special Deputy Commissioner has been appointed to act on RERA recovery certificates. If your certificate is pending for months, a writ petition in the High Court is one option.

Either side can appeal a K-RERA order to the Real Estate Appellate Tribunal. A builder who appeals must first deposit a part of the amount ordered before the appeal is heard.

RERA or consumer court?

You can also approach the consumer commission for deficiency in service by a builder. The Supreme Court has held that the RERA Act does not take away this right. K-RERA is usually faster and cheaper, and its interest rate is fixed by the rules. A consumer commission can award compensation in the same case. Avoid running the same claim in both forums at once. Choose based on the amount, the builder’s condition and how quickly you need an order.

Questions people ask

How do I file a RERA complaint against a builder in Karnataka?

Register on rera.karnataka.gov.in, log in to the complaint section, fill in the form, upload your agreement and payment proofs, and pay the fee online. K-RERA then issues notice to the builder and fixes hearings.

What interest does a builder pay for delayed possession in Karnataka?

The rate under the Karnataka RERA Rules is SBI’s highest marginal cost of lending rate plus 2%, for every month of delay until possession, or on the refund if you withdraw.

Can I get a full refund from the builder for delay?

Yes. Under Section 18 of the RERA Act you can withdraw and get back all amounts paid, with interest, plus compensation decided by the Adjudicating Officer.

Is there a time limit to file a RERA complaint?

The RERA Act does not set a specific deadline for complaints, but file soon after the possession date is missed. Delay makes evidence harder and gives the builder more arguments.

What if the builder does not pay after the RERA order?

K-RERA issues a recovery certificate and the amount is recovered as arrears of land revenue. If that stalls, the High Court of Karnataka has directed authorities to act on such certificates without delay.
