Ramesh did everything by the book on a resale flat in Bellandur. He took a fresh encumbrance certificate, it showed no loans, and he paid the seller in full. Six months later a bank notice arrived. The seller had taken a loan against the flat years earlier by depositing the original title deeds, a form of mortgage that never appeared in the encumbrance certificate because it was never registered with the sub registrar. Ramesh had bought a home the bank could still claim. A single ten rupee search on a government portal called CERSAI, run before he paid, would have shown that loan in seconds.

The short answer. CERSAI is the central government registry where lenders record loans secured against property, and a quick public search reveals charges that an encumbrance certificate can miss, especially equitable mortgages created by depositing title deeds. The trade off is almost comically lopsided. The search costs about ten rupees and takes minutes, while skipping it can cost you the entire value of the flat. For a resale purchase there is no good reason not to run it.

What is CERSAI, and what does it record?

CERSAI is the Central Registry of Securitisation Asset Reconstruction and Security Interest of India, an online registry set up by the government to record the claims that banks and lenders hold over property. When a lender takes a property as security for a loan, it registers that security interest on CERSAI. The registry then acts as a single national place to check whether a given property, or a given person, carries a live loan against it. For a buyer, this is a direct answer to the most important question in a resale deal. Is anyone other than the seller able to claim this home. If a bank has a registered charge, the answer may be yes, and you want to know that before your money moves, not after.

You can run the check yourself on the official CERSAI portal. It is a public facility, designed to be used by ordinary buyers and not just banks, and the fee is a token amount.

The registry exists precisely because loans against the same property, taken from different lenders, once caused chaos and fraud. By putting every registered security interest in one national place, CERSAI lets a lender, and now a buyer, see at a glance whether a property is already pledged. For a city like Bengaluru, where a large share of resale flats were themselves bought on home loans, this is not an exotic check for unusual cases. It is a routine reality that most resale flats have carried a loan at some point, and your only job is to confirm that any such loan is closed before you take over.

Why is CERSAI different from an encumbrance certificate?

Because the two records capture loans in different ways, and one has a blind spot the other covers. An encumbrance certificate lists documents registered with the sub registrar for a property over a period, so it catches a mortgage that was formally registered there. But India also recognises the equitable mortgage, created simply by depositing the original title deeds with a lender, and this kind of mortgage often does not require registration with the sub registrar. That means it can be completely absent from the encumbrance certificate while still being a very real loan against the flat. Lenders do, however, register these security interests on CERSAI. So the exact loan that slips past the encumbrance certificate is the one CERSAI is built to reveal. This is why the two checks are partners, not substitutes.

Ramesh learned this the hard way. His encumbrance certificate was clean and truthful about registered documents, but the loan against his flat lived outside that record. Treat a clean encumbrance certificate as necessary but not sufficient, and let CERSAI cover its blind spot.

How do you actually run a CERSAI search?

You run two searches, not one, and each catches a different thing. On the CERSAI public search, an asset based search looks up charges filed against the property itself, using its details, while a borrower based search looks up charges filed against the owner, using their PAN or name. A dishonest or disorganised record can hide a charge under one and not the other, so running both closes the gap. Each search costs only around ten rupees, and you can view and download whatever registered security interests come up. The table below places CERSAI alongside the other checks a Bengaluru buyer should run.

Read the table as a layered defence. No single record is complete on its own, but run together they leave very little room for a hidden loan to survive undetected.

What do you do if a charge shows up?

If CERSAI shows a live charge, do not pay the balance until it is cleared and released. A charge appearing is not necessarily the end of the deal, because many sellers are simply repaying a home loan they took on the same flat. The correct path is to make the closure part of the transaction. Ask the seller for a loan closure statement from the bank, arrange for the loan to be paid off, often from your own purchase money routed directly to the lender, and insist that the bank issue a no dues letter, release the original title deeds, and remove the charge. Only then is the flat truly free. A charge that is still live when you register can follow the property into your hands, so the timing of the release matters as much as the release itself.

Handled well, a seller loan is a routine part of a clean resale. Handled carelessly, it is how a buyer inherits someone else debt. The difference is entirely in whether you check first and sequence the payments correctly.

What CERSAI does not tell you

CERSAI is powerful, but it is not the whole of due diligence, so do not let a clean result lull you. The registry shows registered security interests, which means loans and charges that a lender has actually filed. It does not confirm that the seller has good title, it does not reveal a private dispute between family members, and it will not show a pending court case that no lender has registered a charge over. A charge can also, in rare cases, be filed late or with an error, so a clean CERSAI result is strong comfort rather than an absolute guarantee. The sensible reading is to use CERSAI for exactly what it does best, catching bank loans and especially the equitable mortgages that escape the encumbrance certificate, while continuing to verify title, approvals and litigation through the other checks. Layer the records, never lean the whole weight of a purchase on any single one, and you protect yourself the way a careful lender would protect itself.

How should a Bengaluru buyer fold this into due diligence?

Make CERSAI a fixed step in your resale checklist, run at the same time as the encumbrance search. Given how cheap and fast it is, there is no reason to treat it as optional. Work through the steps below in order.

1. Take a fresh encumbrance certificate for the property covering a long enough period.
2. Run a CERSAI asset based search using the property details.
3. Run a CERSAI borrower based search using the seller PAN or name.
4. Compare all three records and list every charge that appears in any of them.
5. For each live charge, obtain the lender closure statement and release commitment in writing.
6. Route the payoff of any existing loan directly to the lender from your purchase funds.
7. Confirm the charge is released and original title deeds are handed over before you register.

This routine turns a frightening risk into a manageable checklist. None of it requires a lawyer to begin, though a good one will do all of it as a matter of course, and the cost of the searches together is a rounding error next to the price of the flat. Our guide on the encumbrance certificate and title search in Karnataka covers the first step in depth, and our broader explainer on title search and legal due diligence shows where CERSAI fits in the full picture. For a resale unit in a project such as Birla Evara off Sarjapur Road, running both the encumbrance and the CERSAI checks before you release money is the single cheapest insurance you will ever buy on a home, and it is one you can arrange yourself in an afternoon.

Common questions from Bengaluru buyers

What is CERSAI and why should I check it before buying?

CERSAI is the central government registry where banks record loans secured against a property. A public search tells you whether an active charge exists on the flat or against the owner. Running it before you pay protects you from buying a home that a lender can later claim, which is one of the costliest mistakes a resale buyer can make.

Does the encumbrance certificate not already show every loan?

Not always. An encumbrance certificate reflects documents registered with the sub registrar, but an equitable mortgage created by simply depositing title deeds with a bank is often not registered there. Such a loan can be missing from the encumbrance certificate yet appear on CERSAI. That gap is exactly why you run both checks rather than relying on one.

How do I search CERSAI and what does it cost?

Go to the CERSAI portal, open Public Search, and run two searches. An asset based search uses the property details, while a borrower based search uses the owner PAN or name. The fee is only about ten rupees per search. You can view and download the registered security interests found against the property or the person.

What should I do if CERSAI shows a charge on the flat?

Do not pay the balance until it is cleared. Ask the seller to obtain a loan closure statement and a no dues or release letter from the bank, and ensure the charge is satisfied and the original title deeds are released at or before registration. A charge that is live at registration can follow the property to you.
