Flat Not Ready on Time? Your Refund and Interest Options Under RERA Section 18

Suppose a buyer in Bangalore was promised keys in March and it is now well past that month with no sign of a handover letter. The law has a ready answer for that situation in Section 18 of the RERA Act. The sections below explain what a buyer may ask for, how Karnataka sets the interest, which date counts and what to do before approaching the regulator.
When Section 18 Applies
The provision is triggered when a builder fails to finish and hand over any apartment, plot or building by the date in the sale agreement. It is also triggered if the builder stops work because its registration was suspended or revoked. From then on the buyer, who is called the allottee in the Act, has a free choice that the builder cannot override.
The refund right is also stated in Section 19(4). Section 18(2) and 18(3) add compensation for defects in the title to the land and for any further breach by the builder.
Route One: Leave and Take the Money Back
A buyer who withdraws is entitled to every rupee paid, with interest, and to compensation if the adjudicating officer grants it. The booking is cancelled, and the builder may sell the flat to someone else. This route makes sense for a buyer with doubts about completion, or one who has already found another home.
Route Two: Stay and Collect Monthly Interest
A buyer who stays holds on to the flat at the price already agreed. Interest on the amount paid accrues for each month of delay and keeps running right up to handover. This route suits someone who likes the flat and can see the work approaching its end.
Which Date Is the Deadline
The only date that matters is the one in the registered agreement. A verbal assurance, a brochure line or a hoarding adds nothing to it. If the agreement has a grace period expressed in plain words, it is normally added before any delay is counted.
Do not confuse that date with the completion date displayed on the state's RERA portal. The portal date is what the builder told the regulator, and it can be later than the one promised to the first customers. When registration is extended, work may lawfully continue, yet the buyer's claim still follows the agreement.
How Karnataka Fixes the Interest
Parties do not negotiate this rate. The 2017 Karnataka rules, in Rule 16, set it at SBI's highest marginal cost of lending rate plus 2%. Because the bank revises its benchmark from time to time, the number on the day the order is passed is what applies.
Fairness runs both ways here. A buyer who misses an instalment pays the builder interest at the same rate, and a builder who is late pays the buyer at that rate. Agreements that charge buyers 18% but give a token amount per sq ft for delay are out of step with the rule.
A Sample Calculation
Imagine Rs. 60 Lakhs has been paid and the keys arrive ten months late. Use 11% a year purely for illustration. One year of interest is Rs. 6.6 Lakhs, which is Rs. 55,000 a month, so the ten months add up to Rs. 5.5 Lakhs.
A refund works differently. Orders of the Karnataka regulator in refund cases commonly count interest on every instalment from its own payment date until the money is returned. After several years, that figure is much bigger than one year of delay interest, and under Rule 17 a refund that has fallen due must reach the buyer in sixty days.
Leaving or Staying: Questions to Settle First
Both options carry a cost that the statute does not spell out. Taking a refund means giving up a home that may have appreciated. Staying preserves that gain, though the project might slip further.
Honest answers to these questions usually point to the right choice.
- How much of the structure is complete, and is anybody working at the site each week?
- Has an occupancy certificate application gone in, or is the building still being raised?
- What would a comparable flat nearby fetch today?
- Does the builder honour earlier regulator orders, or are recovery proceedings piling up?
- How many months can the family pay rent and a loan instalment together?
Borrowers face an extra step. The bank has first claim on refunded money, and the loan stays alive until it is closed, which means instalments go on during the case. Write to the lender before filing and find out how it wants the refund routed.
Interest Is Not Compensation
Interest repays the cost of keeping a buyer's money. Compensation covers a separate loss, for instance the rent paid for extra months or a replacement home that now costs more. The Act hands these to different officers.
In November 2021 the Supreme Court clarified the split in Newtech Promoters and Developers v. State of Uttar Pradesh. Refund and interest belong to the regulatory authority, and compensation goes to the adjudicating officer (Sections 71 and 72). The judgment also called the refund right on delay unconditional, irrespective of why the delay occurred.
Natural Calamity Defences
A frequent builder response is that events beyond its control caused the slip. Section 6 limits such events to a natural calamity disturbing regular development, such as an earthquake, cyclone, flood, drought or fire, or to war. Shortages of labour or sand, weak sales and slow approvals are not listed.
If a real event is proved, the possession date shifts by the length of the event, which shrinks the delay but keeps the claim alive. Buyers who owe instalments should expect a demand for interest on the overdue amounts, so settle dues or note in writing why they were held.
Handover Day Pitfalls
Taking the keys late does not erase interest earned up to the handover day. The trouble is sometimes found in the possession letter, which may say that all claims against the builder are given up. Read it first, object in writing to any such wording and hold on to a copy.
Handover ought to arrive with the tower's occupancy certificate, as an offer without it is incomplete. Record when the offer was made too, since the delay period normally closes then.
Before Filing
Complaints go to K-RERA, the Karnataka regulator, and good preparation counts for more than the filing itself. The following steps make a claim solid.
- Locate the possession clause in the registered agreement and copy out the date and any grace period
- Prepare a payment list showing dates, amounts and receipt numbers
- Take photographs of the site and keep every email where the builder moved the date
- Send the builder a written notice naming the delay and the chosen remedy, with proof that it was received
- Open the project entry on the state portal to check registration status and previous orders
- Submit the complaint, attaching the agreement, receipts and letters
Under the Act, a claim does not wait for any minimum period of delay. The apex court has additionally said that a buyer may approach the consumer commission, since the remedies run in parallel. To compare projects on delivery record, buyers can reach our team via the contact page.
