Quick answer. When your builder misses the possession date in your agreement, Section 18 of the RERA Act gives you two clear choices: withdraw and demand a full refund of what you paid plus interest, or keep the flat and claim interest for every month of delay. File before your state RERA authority or a consumer commission.
You signed the agreement, you paid, and the date came and went. The keys never arrived. Your savings are locked inside a half-built tower, you are paying rent and an EMI at the same time, and the builder has stopped answering your calls. That trap, money in, nothing out, is exactly what the law was written to break. This guide is not about filling one form. It is the menu of remedies open to you, and how to pick the one that gets your money or your flat back fastest.
Everything starts with one section. Section 18 of the Real Estate (Regulation and Development) Act, 2016 gives an allottee an unqualified right the moment the builder fails to hand over possession by the agreed date. You choose one of two paths, and the choice is yours, not the builder's.
A force majeure clause or a fine-print grace period in the builder's draft cannot quietly cancel this right. The right flows from the statute, not from the contract the builder wrote.
The rate is fixed by your state RERA rules, not by the builder. Most states peg it to the State Bank of India's highest Marginal Cost of Lending Rate, commonly plus two per cent, and a few apply a slightly different margin. The same rate applies both ways, so the builder cannot charge you a high penalty for late payment while paying you a token rate for years of delay. Check the exact formula in your state RERA rules before you put a number in your claim, and verify the current rate on your state RERA portal.
This is where most buyers freeze. You have more than one door, and picking the right one saves months.
If your project is registered with RERA, the state real estate authority is built for exactly this dispute. It hears delay and refund claims, fixes the interest, and can order the promoter to pay. Filing is online on your state RERA portal, the fee is modest and varies by state and claim size, so confirm it on the portal before you pay. Use our companion walkthrough on the RERA complaint for builder delay for the form-by-form filing detail. Before you file, it is worth a two-minute check on how to verify a RERA project so you quote the correct registration number and promoter name.
You are not locked out of consumer courts. The Supreme Court in Imperia Structures Ltd versus Anil Patni (2020) held that RERA does not bar a complaint under the Consumer Protection Act. A homebuyer is a consumer, and you may choose the consumer route instead. Pick the forum by the value of your claim: the District Commission handles smaller claims, the State Commission the middle band, and the National Commission the largest. The exact money limits are set by the Consumer Protection Act and have been revised, so verify the current pecuniary slab on consumerhelpline.gov.in. Do not run both forums for the same relief at the same time, choose one.
If the builder is genuinely insolvent and the project is dead, a big group of buyers can act together as financial creditors under the Insolvency and Bankruptcy Code. This route is only open when the application is brought by a large minimum group of allottees of the same project, so it suits organised buyer associations, not a lone purchaser. Treat it as a last resort when refund orders cannot be recovered any other way.
Ask yourself one question first: do you still want this flat?
Then pick the forum by claim size and by whether the project is RERA registered. Registered project and a clean delay claim, go to RERA. Larger or older grievance you would rather take to a consumer bench, go there instead.
Keep the spine of your evidence ready before you file: the builder buyer agreement, every payment receipt and bank statement, the allotment letter, the sanctioned completion date, and all the silence in writing, emails, messages and notices that prove the delay. Understanding the difference between your sale deed and agreement to sell helps you point the authority to the exact clause that fixed your possession date.
Figure: step-by-step flow. If a step stalls, use the grievance or RTI route shown.
Winning the order is not the same as getting paid. Builders stall here too. If the promoter does not comply, you do not start again.
So come back to where you started. Money in, nothing out is not a dead end, it is a claim. Section 18 turns your locked savings into either a refund with interest or a flat that finally costs the builder for every late month. Pick your door, gather your receipts, and file.
No. Section 18 makes the choice yours. If the builder misses the agreed possession date, you decide whether to withdraw for a refund with interest or stay and claim delay interest. A clause in the builder's agreement cannot take that statutory choice away.
Such clauses cannot wipe out your Section 18 right. Tribunals have repeatedly held that a routine grace period or a vague force majeure plea does not extinguish the allottee's statutory entitlement to interest or refund for unreasonable delay.
Both doors are open after Imperia Structures versus Anil Patni. If your project is RERA registered and the claim is a clean delay or refund, RERA is usually faster. For some buyers a consumer commission suits better. Choose one forum for the same relief, do not run both at once.
The rate is set by your state RERA rules, generally linked to the State Bank of India MCLR plus a fixed margin, and the same rate applies to both sides. Confirm the exact figure on your state RERA portal before you quote a number in your claim.
Apply to execute the order. A RERA money order can be recovered as arrears of land revenue, allowing the authority to attach the builder's assets. You can also file an RTI for the order copy and project records to build pressure.
A continuing default keeps the cause of action alive, and several authorities have held there is no rigid limitation bar for ongoing delay. Still, do not sit on your claim. File promptly and verify the position for your state before assuming any time limit.
Not alone. The IBC homebuyer route needs a large minimum group of allottees of the same project to file together. It is an option for organised buyer associations when an insolvent builder cannot be made to pay any other way.
