By 2026 a Bengaluru couple had waited two years past the possession date written into their agreement for a flat that was still unfinished. The builder offered fresh promises and little else. What the couple did not know at first was that the law gave them a clear choice and a place to enforce it. Under the real estate law, a buyer facing delayed possession can either stay and claim interest for the wait, or walk away with a full refund plus interest, and the state authority exists to make that right real. Knowing this changes a buyer from a supplicant into someone with a remedy.

The short answer. If a builder misses the possession date in your agreement, Section 18 of the real estate law gives you two options: continue in the project and claim interest for the delay, or withdraw and claim a full refund of what you paid, with interest. You enforce this by filing a complaint with the Karnataka real estate authority. The trade off is which remedy fits your life, keeping the home you still want with compensation for the wait, or getting your money back to move on, and neither is a favour the builder grants, but a right the law gives you.

What does the law say when possession is delayed?

The law treats a missed possession date as a breach that triggers real remedies for the buyer. Under Section 18, if the builder fails to complete or hand over the flat by the date promised in the agreement, you are entitled either to take possession with interest for every month of delay, or to withdraw from the project and receive a full refund of the amounts you paid, together with interest. Courts have gone out of their way to describe this right as absolute and unconditional, meaning it does not depend on the builder's excuses or on a clause buried in the agreement. That is a powerful position for a buyer who has been kept waiting, and the first step to using it is simply to know that it exists.

The date that matters is the one written into your agreement, not the softer timeline a salesperson may have mentioned. This is why reading the agreement for the committed possession date, and keeping that document safe, matters so much from the very start. When a builder later points to construction difficulties or approvals as the reason for delay, those explanations do not erase the agreed date. The date is the line the law measures the delay against, and your right flows from the gap between that promise and reality.

Which of the two remedies should you choose?

The choice between staying and leaving turns on whether you still want the home. If the project is genuinely close to completion and you still want to live there, continuing while claiming interest for the delay lets you keep the flat and be compensated for the wait. If the delay is long, the builder unreliable, or your plans have changed, withdrawing with a full refund plus interest lets you recover your money and move on. The table below sets the two remedies side by side.

Neither choice is automatically better. The right one depends on your circumstances, so decide what outcome you actually want before you file, because the relief you ask for shapes the order you can get.

What interest can you expect on the money?

Interest on a delay or a refund is paid at a prescribed rate, not a figure the builder decides. The rate is set by the rules, usually as a bank benchmark plus a margin, and in practice it has commonly worked out to somewhere around ten to eleven percent a year on the amounts you paid, calculated from the date of default. Because the exact rate and the way it is applied can change, treat any figure as indicative and confirm the current basis when you file. The important point for a buyer is that the interest is meant to compensate you for the money you parted with and the time you lost, so it is a real number, not a token, and it is part of what makes the remedy worth pursuing.

It is worth separating interest from compensation in your own mind. The interest on the delay or the refund is one thing, meant to make up for the money and the time. Compensation for a specific loss you can prove, such as rent you had to keep paying because your home was late, can be a separate claim decided by the authority. Being clear about what you are asking for, and why, helps the authority give you a precise order rather than a vague one.

How do you file a complaint with Karnataka RERA?

You file online through the official Karnataka real estate authority portal, and a well prepared complaint is far more likely to move quickly. Set out the facts clearly and attach the evidence. Work through the following steps.

1. Gather the sale agreement, all payment receipts, and the project's registration details.
2. Note the agreed possession date and the actual position today, with the length of the delay.
3. Decide the relief you want, whether possession with interest, a refund with interest, or compensation.
4. Consider sending a written notice to the developer first, and keep a copy of it.
5. Open the official Karnataka RERA portal and complete the complaint with each violation and its dates.
6. Reference Section 18 for the delay, and upload the agreement, receipts and any notice or response.
7. Pay the prescribed fee, submit, and keep the acknowledgement to track the complaint.

The stronger your paper trail, the stronger your complaint. The same possession documents we set out in our guide to the apartment possession handover checklist are the evidence that shows exactly what was promised and what was delivered, and the occupancy certificate you would insist on before possession is often the very thing a delayed project has failed to obtain.

How long does it take, and what should you expect?

A complaint takes time, so it helps to go in with realistic expectations. Many cases move from filing to an order over several months, and actually recovering money can take longer where the matter is contested or the developer is slow to comply. This is not a reason to avoid the process, but a reason to prepare well, keep your documents in order, and consider legal help for a large claim. Knowing the likely timeline also feeds back into your choice of remedy, since a buyer in urgent need of their money may weigh a refund differently from one who can wait for possession with interest. Going in informed, rather than surprised, is what keeps the process from wearing you down before it delivers a result.

How should a buyer use this right well?

Use the right early and in an organised way, rather than after years of unenforced promises. If you are weighing a project that is running late, such as any under construction launch like Brigade Citrine, note the agreed possession date in your agreement, because that date is the line the law measures against. If it is missed, you do not have to rely on the builder's goodwill. You have a remedy, a forum, and a defined right to interest or a refund. The couple in our opening scene eventually used exactly this, and the lesson from their two lost years is simple. Know your possession date, keep your documents, and act on your rights rather than waiting for a promise to come good. The buyers who fare best are not the loudest, but the ones whose paperwork tells a clear, dated story that the authority can act on.

Frequently asked questions

What can I do if a builder delays possession of my flat?

You can raise the matter with the Karnataka real estate authority. When a builder misses the agreed possession date, the law gives you two paths: continue in the project and claim interest for the delay, or withdraw and claim a full refund of what you paid, together with interest. Which you choose depends on whether you still want the home.

What is my right under Section 18 of the real estate law?

Under Section 18, if the builder fails to give possession by the date in your agreement, you have the right either to take possession with interest for the delayed period, or to withdraw from the project and receive a full refund of the amounts paid, along with interest. Courts have described this right as absolute.

How do I file a complaint with Karnataka RERA?

You file online through the official Karnataka RERA portal. Set out the date of your sale agreement, the agreed possession date, the current position and each violation with its dates, and state the relief you want, whether possession by a date, a refund with interest, or compensation. Upload your agreement, payment receipts and any notice sent to the developer.

How long does a Karnataka RERA complaint take?

It varies with the case and the builder. Many complaints move from filing to an order over several months, and actually recovering money can take longer where the matter is contested or the developer is slow to comply. Knowing this timeline early helps you weigh whether to press for possession with interest or to seek a refund.
