Corpus and Sinking Fund: What a Buyer Must Check at Handover

When an apartment community in east Bengaluru finally formed its owners' association, the new committee asked the builder a simple question: where is the corpus fund each of us paid at possession, and what is the balance today? The answer came slowly, without bank statements, without audited accounts, and with a chunk of the interest apparently missing. Every owner had paid into that fund trusting it would be there when the building needed it, and now no one could say for certain that it was. In Bengaluru, the money you hand over at possession for future repairs is only as safe as the paperwork you insist on.

The short answer. At possession you typically pay a one-time corpus fund and some advance maintenance, and the community also builds a sinking fund over time for major periodic repairs. Under RERA, the builder must keep these in dedicated accounts, cannot divert the interest they earn, and must transfer the balances to your owners' association with audited accounts once it is formed. The trade-off to watch is diligence versus trust: these funds are real money that belongs to the community, and getting a clean, documented handover is what keeps them from quietly leaking away.

What is a corpus fund, and what is it for?

A corpus fund is a one-time contribution, collected from each buyer usually at possession, that forms a permanent financial reserve for the community. It is meant to sit as a base against which major, unexpected needs can be met, whether large repairs, emergencies, or eventual redevelopment, with the idea being that the principal is preserved and the community draws mainly on the returns it generates rather than depleting it casually. The amount per flat varies widely, from a modest sum to over a lakh, depending on the project.

Because it is a permanent reserve rather than a spending account, the corpus fund should not be used for routine monthly maintenance, and it should not be quietly consumed during the years the builder runs the property. For a buyer, the corpus is money paid for the long-term security of the building, so its very permanence is the reason it must be tracked, transferred and preserved rather than treated as just another line on the cost sheet. Because it can run to a large sum once every flat's contribution is pooled, a corpus for a mid-sized community is often several crore in total, which is exactly the kind of money that rewards careful custody and punishes casual record-keeping.

How is a sinking fund different?

A sinking fund is a reserve the community accumulates over time, usually through regular contributions, specifically to pay for planned major repairs down the line. Where the corpus is a one-time permanent base, the sinking fund is built up gradually and is earmarked for predictable big-ticket work, such as repainting the building, replacing lifts, or major plumbing and structural upkeep, that would be painful to fund from a single month's maintenance collection. It smooths large future costs across many small contributions.

The two are complementary rather than interchangeable. The corpus provides a standing cushion, while the sinking fund is the deliberate savings pot for known future works. A well-run community keeps both, understands what each is for, and does not raid one to cover the other. Knowing the distinction lets you read your maintenance accounts sensibly and ask the right questions about how each fund is being maintained. It also helps you judge whether your monthly maintenance is fair, since a community that quietly skips building a sinking fund may look cheaper each month but will face a painful special levy when a lift or a coat of paint finally comes due.

What does a builder owe you at handover?

The builder owes you a clean, documented transfer of these funds to the owners' association, not a vague assurance. Under RERA, the promoter maintains the project until the owners' association is formed, and must then hand over the balances in the maintenance and corpus accounts to that association, supported by audited accounts for the period the builder managed the property. Crucially, the builder is expected to hold these monies in dedicated accounts and cannot divert the interest they earn into its own pocket.

Read the last row as the one builders most often get wrong. The interest these funds earn belongs to the funds, and therefore to the community, not to the developer managing them. When the association is formed, it is entitled to the principal and the interest together, with a statement it can verify, which is why the audited handover is the heart of the matter rather than a formality. A community that lets this pass unexamined can find, years later, that no one can reconstruct what was collected, what was spent, and what should still be sitting in the account.

What documents should the association collect?

Insist on paperwork that lets the community verify every rupee, because a transfer without documents is not really a transfer. The association should collect a statement of each maintenance, advance-maintenance, corpus and sinking-fund account showing the amounts collected per flat and the dates, the closing balance in each account backed by current bank statements, and an income-and-expenditure statement for the builder-managed period certified by a chartered accountant. It should also confirm that interest earned stayed within the funds and obtain a dated receipt for the transfer to the association's own bank account.

This is the difference between a handover you can stand behind and one you will spend years chasing. A community that takes possession of these funds with full documentation starts its financial life on solid ground, while one that accepts a lump sum with no accounts may never establish what was actually collected or spent. The paperwork is tedious, but it is precisely where the money is protected, and it is best gathered at handover rather than reconstructed later.

What can you do if the funds are not handed over?

If a builder stalls or hands over incomplete accounts, the community has recourse rather than having to simply absorb the loss. Because the obligation to transfer the corpus and maintenance balances with audited accounts flows from RERA, an association that is denied a proper handover can raise the matter with the regulator, and developers who fail to transfer the full amount or who misuse the funds can face action, including being directed to refund with interest. The community's leverage is strongest when it has documented what it paid and what it is owed.

For a Bengaluru community, the project and its obligations are on the Karnataka RERA portal, rera.karnataka.gov.in, which is the reference point for what the builder committed to. The practical lesson for an individual buyer is to keep your own possession-stage receipts for corpus and maintenance, because your records feed the association's case, and a fund that is well documented flat by flat is far harder for anyone to lose track of.

What should a buyer check about these funds?

Treat the corpus and maintenance money as seriously as the price of the flat, and keep the paper trail from day one.

1. Get a receipt at possession for the corpus fund and advance maintenance you pay.
2. Confirm the corpus is a permanent reserve, not routine maintenance you are prepaying.
3. Ask which dedicated accounts hold the corpus, maintenance and sinking funds.
4. Ensure interest earned on the funds stays within them, not with the builder.
5. When the association forms, demand audited accounts for the builder-managed period.
6. Obtain a dated receipt for the transfer of balances to the association's account.
7. Escalate an incomplete or missing handover using the project's RERA obligations.

Doing this protects money that is genuinely yours and the community's, not the builder's to keep. Because these funds are handed over alongside the common areas, they sit within the wider transition covered in our guide to common area handover and the owners' association, and the corpus itself often first appears as a line on the builder's cost sheet, which is where to first ask what it is and where it will be held. In a project such as Adarsh Rosewood in Bellandur, as anywhere, the corpus is worth tracking from the moment you pay it.

Frequently asked questions

What is the difference between a corpus fund and a sinking fund?

A corpus fund is a one-time contribution, usually paid at possession, that forms a permanent reserve for major or emergency needs. A sinking fund is built up over time through regular contributions and is earmarked for planned major repairs like repainting or lift replacement. The corpus is a standing cushion; the sinking fund is deliberate savings for known future works.

Does the builder have to hand over the corpus fund to the association?

Yes. Under RERA, the builder maintains the project until the owners' association is formed and must then transfer the balances in the maintenance and corpus accounts to it, with audited accounts. The builder cannot keep the interest these funds earn. If a handover is incomplete or missing, the association can raise it with the regulator.

Who keeps the interest earned on the corpus and maintenance funds?

The funds do, and therefore the community. Interest earned on the corpus and maintenance monies must stay within those accounts and cannot be diverted to the builder managing them. When the association is formed, it is entitled to both the principal and the accumulated interest, supported by a statement it can verify.

What should I keep to protect my share of these funds?

Keep your possession-stage receipts for the corpus fund and any advance maintenance you paid, since your records feed the association's case at handover. Ask which dedicated accounts hold the funds, and when the association forms, ensure it obtains audited accounts and a dated transfer receipt. A fund documented clearly is far harder to lose track of.
