K-RERA Buyer Guide: How Karnataka’s RERA Protects Your Property Investment in 2026
Before RERA came into force in 2017, buying an under-construction flat in Bengaluru carried risks that most buyers did not fully understand at the time of purchase. Developers collected substantial upfront payments, diverted funds to other projects, and delayed handover by years without legal consequence. The Karnataka Real Estate Regulatory Authority — K-RERA — was established specifically to end that environment. In 2026, K-RERA buyer protection is robust enough that a buyer who does their due diligence upfront and understands their legal rights has strong recourse if a builder fails to deliver.
This guide covers everything a 3 BHK buyer in Bengaluru needs to know: how to verify a project before paying anything, what the 70% escrow rule actually guarantees, what compensation you can claim if your builder delays, and the step-by-step process for filing a formal complaint. It is intended as a practical reference, not legal advice — for significant disputes, consult a RERA-specialised lawyer.
What’s Covered in This K-RERA Buyer Guide
Mandatory Registration: What the K-RERA Buyer Guide Requires You to Verify
The most fundamental rule of buying any property in Karnataka is this: no developer can legally advertise, sell, or accept a booking amount for a project unless it is registered with K-RERA Karnataka. The registration requirement applies to any project with a land area exceeding 500 square metres or more than eight apartments. Sub-registrar offices can refuse to process sale deeds for unregistered projects, and buyers who paid pre-launch amounts for unregistered developments have limited legal recourse under RERA.
Before signing any document or paying any amount — including a nominal “expression of interest” — look up the project’s K-RERA registration number on the official portal. The registration page shows the project’s sanctioned building plan, land title details, approved layout, list of promoters, declared possession date, and quarterly construction progress reports. If any of these are missing or the registration number cannot be found, do not proceed.
What to Check on the K-RERA Portal Before Buying
| Check Point | What to Verify | Red Flag |
|---|---|---|
| Registration Status | Active registration, not expired or cancelled | Expired registration or no K-RERA number at all |
| Declared Possession Date | Confirmed timeline with buffer for construction | Possession date already past with no extension filing |
| Construction Progress | Quarterly reports updated, photos visible | No updates filed in the last two quarters |
| Land Title | Clear title, conversion order if formerly agricultural | Land conversion pending or court disputes noted |
| Approved Units | Your flat number is within the sanctioned plan | Developer selling units beyond the approved count |
The 70% Escrow Rule: The Core Financial Protection
The most important financial protection in the K-RERA framework is the mandatory escrow account. Under the RERA Act, a developer must deposit 70% of all funds received from buyers — including the booking amount, instalments, and any other payments — into a dedicated escrow account for that project. These funds can only be withdrawn in proportion to the verified percentage of construction completed, as certified by an architect and a chartered accountant.
In practice, this means a developer cannot use money you paid for your Sarjapur Road flat to fund land acquisition in Whitefield. The historical pattern of fund diversion — which was the primary cause of stalled projects before 2017 — is structurally blocked by this rule. The escrow account is project-specific and audited. If a developer attempts to withdraw funds disproportionate to construction progress, the escrow bank is legally required to refuse the withdrawal.
The practical implication for buyers: the 70% escrow rule means that even in a worst-case scenario where a developer faces financial difficulty, 70% of buyer funds are ring-fenced within the project. The remaining 30% that developers can retain as working capital is the portion that carries residual risk. Understanding this structure helps you evaluate what “financial risk” actually means in the context of K-RERA-registered projects.
Delay Penalty vs Full Refund: Your Two Legal Options Under the K-RERA Buyer Guide
If your builder fails to deliver possession by the date declared in your registered Agreement to Sale, K-RERA gives you two distinct legal remedies. You must choose one — you cannot simultaneously pursue both for the same period of delay.
Option 1: Delay Compensation (Keep the Flat)
If the project is delayed but substantially progressed, and you still want the flat, you can approach K-RERA to demand financial compensation for the delay. The compensation rate is the State Bank of India’s MCLR (Marginal Cost of Funds based Lending Rate) plus 2%, applied monthly on all amounts you have paid to the developer from the date of promised possession to the actual handover date. This is a legally mandated rate — the developer cannot negotiate it down.
For example, on a ₹1.5 Crore flat where you have paid ₹1.2 Crore, with a current MCLR of approximately 9%, your delay compensation accrues at roughly 11% per annum on ₹1.2 Crore — approximately ₹11,000 per month. For a two-year delay, this amounts to approximately ₹2.64 Lakhs in compensation that K-RERA can order the developer to pay you at the time of possession.
Option 2: Full Refund with Interest (Exit the Project)
If the project is stalled, if the developer is acting in bad faith, or if you simply no longer want the flat, Section 18 of the RERA Act gives you the right to demand a full refund of all amounts paid, plus MCLR+2% interest calculated from the date each payment was made. The developer cannot deduct cancellation charges under this provision. This right applies from the day the possession date passes without handover — no additional notice period is required.
The refund process typically takes 3–6 months from the date of K-RERA’s order, depending on the developer’s financial position and any appeals filed. If the developer delays the refund after an order, you can approach K-RERA again for enforcement, including attachment of the developer’s assets.
How to File a K-RERA Complaint: Step-by-Step
Step 1: Gather Your Documentation
Before filing, compile the following in PDF format: the registered Agreement to Sale, all payment receipts with bank reference numbers, written correspondence with the developer (emails or letters) where you raised the delay concern and received no adequate response, and any formal possession notice (or lack thereof). The strength of your complaint depends on documented evidence, not verbal assertions.
Step 2: File Online on the K-RERA Portal
Complaints are filed at rera.karnataka.gov.in using the online complaint module. The filing fee is nominal (typically ₹1,000). Upload your documentation, specify the relief you are seeking (delay compensation or full refund), and calculate the compensation amount based on the MCLR formula. You will receive a complaint registration number for tracking.
Step 3: Conciliation Forum
K-RERA typically routes complaints through a Conciliation Forum first, where a mediator (often a representative from CREDAI Bengaluru alongside a consumer representative) attempts to negotiate a settlement. If the developer agrees to a structured payment plan or an accelerated handover, the dispute can end at this stage. Many straightforward delay disputes are resolved through conciliation without a formal hearing. If conciliation fails, the case moves to the K-RERA adjudicating authority.
Step 4: K-RERA Adjudicating Authority
At the formal hearing stage, you or your legal counsel presents the case before the K-RERA Adjudicating Officer. K-RERA aims to dispose of complaints within 60 days of registration, though complex cases take longer. The order issued by the Authority is legally binding. Developers who fail to comply with K-RERA orders face penalties and, ultimately, the attachment of project assets. If the developer appeals to the Karnataka Real Estate Appellate Tribunal (K-REAT), they must first deposit 30% of any financial penalty or 100% of any refund amount directed before the appeal is heard.
Conclusion
The K-RERA buyer guide framework has fundamentally changed the risk calculus for under-construction property purchases in Karnataka. The 70% escrow rule, mandatory project registration, legally enforceable delay penalties, and the right to a full refund with interest have created a buyer-protective environment that did not exist before 2017. None of this eliminates risk entirely — project delays still happen, and enforcement takes time — but buyers who verify K-RERA compliance before paying any amount, and who understand their legal options in advance, are in a materially stronger position than pre-RERA buyers ever were. Do your verification on K-RERA before every transaction, keep every document, and know that the law is on your side if a builder fails to deliver.

Frequently Asked Questions
What is K-RERA and why does it matter for buying a flat in Bengaluru?
K-RERA (Karnataka Real Estate Regulatory Authority) is the state regulator established under the central RERA Act 2016. It requires all real estate projects above a minimum threshold to register before marketing or selling any units. Registration mandates the developer to disclose land title, building plans, possession timelines, and financial accounts. It also enforces the 70% escrow rule and gives buyers legal recourse for delays through a dedicated regulatory tribunal. For buyers, K-RERA registration is the minimum proof that a project meets statutory disclosure requirements — buying an unregistered project means no RERA protection.
How do I verify if a Bengaluru project is registered on K-RERA?
Go to rera.karnataka.gov.in and use the “Search Project” function. You can search by project name, developer name, or registration number. The results page shows registration status (active/expired), declared possession date, sanctioned floor plans, and quarterly progress updates. If a project you are considering cannot be found on this portal, or if its registration has expired without a formal extension filing, do not pay any amount until the developer provides a valid explanation.
What is the 70% escrow rule and does it fully protect my investment?
The 70% escrow rule requires developers to deposit 70% of all buyer payments into a project-specific bank account, from which funds can only be withdrawn in proportion to verified construction completion. It significantly reduces the risk of fund diversion — the primary cause of project failures before RERA. It does not fully eliminate risk: the remaining 30% is outside the escrow, and in cases where a developer faces insolvency, recovery may require additional legal proceedings beyond RERA. However, for projects from established developers with K-RERA compliance, the escrow rule provides meaningful financial protection that did not exist before 2017.
Can I claim both delay compensation and a full refund at the same time?
No. You must choose one of the two remedies K-RERA provides. If you want to keep the flat, you claim delay compensation at the MCLR+2% rate for the period of delay. If you want to exit the project, you claim a full refund of all amounts paid plus MCLR+2% interest from the date of each payment. The choice is yours, but it must be made at the point of filing the complaint. Once K-RERA has adjudicated on the basis of one remedy, pursuing the other for the same period requires a separate proceeding and strong grounds.
Should I hire a lawyer to file a K-RERA complaint?
You are not legally required to have a lawyer to file a K-RERA complaint. The portal is designed for self-filing, and for straightforward delay claims with clear documentation, many buyers successfully represent themselves. However, against larger developers who field corporate legal teams, a RERA-specialised lawyer in Bengaluru is strongly advisable — particularly if the amount in dispute exceeds ₹50 Lakhs or if the developer has filed counter-claims. Lawyer fees for RERA matters typically range from ₹15,000–₹50,000 for standard cases, which is proportionate to the protection they provide on a multi-crore transaction.
