How to File a K-RERA Complaint in Bengaluru: A Step by Step Buyer Guide

Picture a Bengaluru buyer in mid 2026, possession long overdue, holding a folder of receipts and a builder who keeps promising a new handover date that never arrives. The agreement said one thing. The site says another. The question that follows is almost always the same: where do I go now, and will it actually move?

For a registered project, the answer often starts with the Karnataka Real Estate Regulatory Authority, better known as K-RERA. It is the forum the law built precisely for this moment, and it is meant to be quicker and lighter than dragging a developer through a civil court.

That said, it is not a magic button. It works within limits, and knowing those limits before you file is what separates a clean win from a frustrating dead end.

The short answer. You file a K-RERA complaint online through the K-RERA portal against a project's registration number, pay the prescribed complaint fee, and ask the authority to direct a refund with interest, completion, or compensation. The trade-off is real: RERA is faster and cheaper than civil court, but it covers only registered projects and registered facts, so unregistered side deals and verbal promises are hard to enforce.

In short, K-RERA in Karnataka lets a buyer file online against a registered promoter for delays, plan deviations, or false advertising, with the official process and current fee both confirmable on the official Karnataka RERA portal.

What is K-RERA and why should a buyer use it?

K-RERA is the Karnataka Real Estate Regulatory Authority, the body where buyers can file complaints against registered promoters for delays, deviations from sanctioned plans, or false advertising. It exists because, before RERA, an aggrieved buyer's only real route was a civil court or a consumer forum, both of which could take years and heavy legal spend.

The appeal for a buyer is the focus. The authority deals specifically with real estate, so it understands possession timelines, escrow obligations, carpet area, and delay interest without needing a long education on how the sector works. For most registered-project disputes, that specialisation is the single biggest reason to start here rather than elsewhere.

It also keeps the burden where evidence already exists. Because registered projects must disclose their plans, timelines, and approvals at registration, much of what you need to prove a breach is already on record. Your job is to show the gap between what was promised and what was delivered.

What grounds can you actually complain about?

You can complain about possession delay, a promoter's refusal to pay delay interest, structural defects within the defect-liability period, and changes to the sanctioned plan made without your consent. These are the typical grounds, and each one maps to a specific obligation the promoter took on at registration or in the agreement for sale.

Possession delay is the most common. If the committed handover date has passed and you are still waiting, that delay is usually the core of the complaint, and it often carries a money claim attached to it. Many buyers do not realise that a delay can entitle them to interest for every month the handover slips, which is why it helps to understand how K-RERA computes delay interest at MCLR plus two percent before you frame your numbers.

Structural defects are a separate and powerful ground. If cracks, leaks, or workmanship issues surface after you move in, you may be able to require the builder to fix them at no cost, which ties directly to the five-year defect liability you can enforce under RERA. A plan deviation, where the builder quietly changes layouts, amenities, or open space without your consent, is the fourth classic ground.

How do you file the complaint, step by step?

You file online through the K-RERA portal, directing your complaint against the project's registration number and paying the prescribed complaint fee. The registration number is the anchor of the whole process, so locate it first; it is what links your grievance to the project's official record with the authority.

Begin by confirming that the project is registered and noting its registration number, then prepare your documents and a clear, dated narrative of what went wrong. Draft your prayer carefully, meaning the specific relief you want, whether that is a refund with interest, a direction to complete and hand over, or compensation. Vague asks weaken otherwise strong cases.

When you submit, you will pay a prescribed complaint fee. We are deliberately not quoting an exact figure here, because fee schedules change; confirm the current amount on the portal before you file so there are no surprises. Once filed, the matter moves toward hearings where both sides present their case.

What documents decide most cases?

Keep the allotment letter, the agreement for sale, payment receipts, and all written communication, because documentary evidence decides most cases. RERA proceedings reward paper. The buyer who can show a signed agreement, a clear payment trail, and a record of broken promises is in a far stronger position than one relying on memory.

Treat your written communication as evidence from day one. Every email, letter, and acknowledged message where the builder admitted a delay or made a fresh commitment can become a building block of your case. Keep it organised by date, because a clean timeline is persuasive in a way that a pile of unsorted papers is not.

Below is a quick map of the common grounds, the relief usually sought, and the evidence that tends to matter most for each.

What can K-RERA order in your favour?

K-RERA can direct refunds with interest, completion of the project, or compensation, depending on what you have asked for and what the facts support. This is the heart of why buyers use the forum: it can order money to move or a project to finish, not merely record that something went wrong.

A refund with interest is common where a buyer wants out of a stalled project. Where the buyer still wants the home, the authority can instead push the promoter toward completion and handover. Compensation can sit alongside either route when the buyer has suffered a quantifiable loss. The right choice depends on whether you still want the flat or your money back. It helps to be honest with yourself here before you draft your prayer, because the relief you ask for shapes the entire complaint. A buyer who is genuinely done with a project and wants to exit should build the case around a refund with interest. A buyer who waited years precisely because they wanted that specific home should frame the matter around completion and handover instead. Trying to keep both doors open at once tends to dilute the case rather than strengthen it, so decide your primary aim early and let the documents support it.

What are the limits you should know before filing?

The core limit is scope: RERA covers only registered projects and registered facts, so unregistered side deals and verbal promises are hard to enforce. If a sales executive promised a clubhouse over the phone but it never reached the registered disclosures or the agreement, that promise is difficult to pin down at RERA.

This is the trade-off worth sitting with. RERA is faster and cheaper than civil court, which is a genuine advantage for most buyers. But that speed comes with boundaries, and a complaint built on facts that were never registered or recorded can stall on exactly that point. Build your case on documents that exist on the official record.

There is also a route beyond the authority. If you disagree with the outcome, orders can be appealed before the Real Estate Appellate Tribunal, so a K-RERA decision is not necessarily the final word for either side.

What is the seven-point checklist before you file?

Run through these seven steps before you submit, so your complaint lands as strongly as it can.

1. Confirm the project is registered with K-RERA and note its exact registration number.
2. Pin down your specific ground, whether possession delay, unpaid delay interest, structural defects, plan deviation, or false advertising.
3. Gather the allotment letter, agreement for sale, and every payment receipt in dated order.
4. Collect all written communication with the builder, especially admissions of delay or new promises.
5. Decide your prayer clearly: refund with interest, completion and handover, or compensation.
6. Check the current prescribed complaint fee on the portal so payment is ready at submission.
7. Keep a backup of everything and note that an unfavourable order can be taken to the Appellate Tribunal.

How do I file a complaint with K-RERA?

You file online through the K-RERA portal against the project's registration number and pay the prescribed complaint fee. Prepare your allotment letter, agreement for sale, payment receipts, and written communication first, then state your ground and the exact relief you want. Confirm the current fee on the portal before submitting.

What can K-RERA order in my favour?

K-RERA can direct a refund with interest, completion of the project, or compensation, depending on the facts and what you have requested. If you want out of a stalled project, a refund route fits. If you still want the home, the authority can push the promoter toward completion and handover instead.

Can I complain about an unregistered project?

This is the hard limit. RERA covers only registered projects and registered facts, so an unregistered project or a verbal side promise is difficult to enforce through K-RERA. Where a project sits outside the registered record, other legal routes may apply, and it is worth taking specific advice on your particular situation.

Can I appeal a K-RERA order?

Yes. K-RERA orders can be appealed before the Real Estate Appellate Tribunal, so a decision at the authority level is not the final word. Either side, the buyer or the promoter, may pursue an appeal, which is why keeping your complete documentary record organised remains useful even after the first order is passed.
