Builder delayed possession of your flat? How a RERA complaint works

What the law says

A delay gives you a choice, and the choice is yours

Section 18 of the Real Estate (Regulation and Development) Act, 2016 is the heart of this. If the builder fails to give you possession by the date fixed in your agreement for sale, you get two options, and you decide which to take. You can withdraw from the project and demand a full refund of the amount you paid, with interest and compensation. Or, if you would rather keep the flat, you can stay in the project and require the builder to pay you interest for every month of delay, right up to the day you actually get possession.

Courts have called this right unconditional and absolute. The Bombay High Court in M/s Man Global v. Jitendra Jain (2023) held that the builder cannot escape it by pointing to administrative hurdles or claiming you agreed to an extension, and it does not depend on outside circumstances. The trigger is the possession date in your agreement, so a one-sided clause that quietly extends that date or shifts the blame for delay onto you is not treated as your genuine consent.

The interest: compensatory, and calculated from when you paid

Two questions always come up: at what rate, and from when.

On the rate, the interest is at a rate "as may be prescribed," which the state RERA rules set, typically as a formula linked to a bank lending rate. What courts have added is a fairness principle: the rate the builder pays you for delay should be equitable, and at least match the rate the builder charges you when you are late with a payment, as the Allahabad High Court applied in Lucknow Development Authority v. Upasana Duggal (2023). This interest is compensatory, meant to make good your loss, not a penalty, and it applies to ongoing projects that were already running when RERA came into force.

On timing, if you take a refund, the interest runs from the dates you actually paid each installment, not merely from the date the builder defaulted, so that you are properly restored, as the Supreme Court held in Experion Developers v. Sushma Ashok Shiroor (2022). One caution: compensation is not a mechanical flat rate applied to everyone. It has to reflect your actual loss, such as the rent you paid while waiting, rather than a single uniform figure, and you cannot expect the same loss to be paid twice under different heads.

Filing a RERA complaint

You enforce these rights by filing a complaint before your state's Real Estate Regulatory Authority against the registered project. In broad terms, the authority decides the refund or the delay interest, while a separate adjudicating officer decides any compensation. An appeal from the authority lies to the Real Estate Appellate Tribunal, and if the builder wants to appeal, the law requires it to make a pre-deposit first. If you win and the builder does not pay, RERA can issue a recovery certificate, which the state authorities are meant to recover like arrears of land revenue.

Your forum: RERA, the consumer commission, or insolvency

You are not locked into one door. The Supreme Court in Pioneer Urban Land and Infrastructure v. Union of India (2019) held that a homebuyer's remedies under RERA, the Consumer Protection Act, and the Insolvency and Bankruptcy Code are concurrent, and it also recognised homebuyers as "financial creditors" under the insolvency law. Section 79 of RERA bars only civil courts from these disputes; it does not bar the consumer commission or arbitration, and Section 88 expressly preserves your other remedies.

So you can elect your forum. RERA is the primary place for an individual grievance about delay; the consumer commission is a genuine parallel option; and you should generally pursue the same claim in one forum, not run the same claim in two at once. Insolvency under the IBC is different in kind: it is a last resort aimed at reviving and completing a stalled project, not a way to recover your individual money, it needs a minimum number of buyers to act together, and purely speculative investors are kept out of it. Reassuringly, if you have already obtained a refund order from RERA, that does not knock you out of the class of financial creditors if the project later goes into insolvency, as the Supreme Court held in Vishal Chelani v. Debashis Nanda (2023).

What you can do

Treat this as your action plan once the builder has already delayed. If you are still deciding to buy, the checks in our guide to buying a flat help you avoid a troubled project in the first place.

1. Decide whether to exit or stay. Section 18 gives you both: a full refund with interest if you withdraw, or monthly delay interest if you keep the flat. The choice is yours, so pick based on whether you still want this home.
2. Fix the agreed possession date and the delay. Your right runs from the date in the agreement for sale. Do not let a one-sided extension clause, or the builder blaming pending approvals, be treated as your consent to wait.
3. Send a written demand to the builder. Ask in writing for either the refund with interest or the monthly delay interest, so there is a clear record before you file.
4. File a RERA complaint. Approach your state RERA authority against the registered project for the refund or interest, with compensation decided by the adjudicating officer, and an appeal to the Appellate Tribunal if needed.
5. Or choose the consumer commission. Because the remedies are concurrent, you can instead go to the consumer commission. Pick one forum for the same claim rather than running both together.
6. Keep every payment record. Interest on a refund is calculated from the dates you actually paid, so keep receipts and bank statements for each installment you made.
7. Treat insolvency as a last resort. Triggering the IBC is about reviving a stalled project, not recovering your money individually, and it needs a minimum number of buyers acting together. It is not the first response to a delay.

Cases that matter

Pioneer Urban Land and Infrastructure v. Union of India (Supreme Court, 2019). Homebuyers' remedies under RERA, the Consumer Protection Act, and the Insolvency and Bankruptcy Code are concurrent, and homebuyers are "financial creditors" under the insolvency law because they finance the project. This is the foundation for your right to choose your forum.

M/s Man Global v. Jitendra Jain (Bombay High Court, 2023). Section 18 gives an allottee an absolute, unqualified right on delay: withdraw and get a full refund with interest and compensation, or stay and be paid interest for every month of delay until possession. The builder cannot escape this by blaming administrative hurdles or an alleged extension.

Experion Developers v. Sushma Ashok Shiroor (Supreme Court, 2022). On a refund, the interest must be calculated from the dates the buyer actually deposited each installment, so that the buyer is truly restored, and consumer forums can order such refunds because the Consumer Protection Act and RERA operate concurrently.

Priyanka Taksh Sood v. Sunworld Residency (Delhi High Court, 2022). Section 79 of RERA bars only civil courts, not the consumer forum or arbitration, and Section 88 keeps RERA in addition to and not in derogation of other laws. A buyer therefore keeps parallel remedies and can choose where to go.
