A year after buying a flat in HSR Layout, a buyer was still getting BBMP property tax notices addressed to the seller. His sale deed was registered, his loan was paid, and yet on the municipal record the flat still belonged to someone else. He had missed the quiet step that makes a purchase complete in the eyes of the civic body: transferring the khata into his own name. Until he did, the city simply did not know he existed as the owner.

The short answer. Khata transfer, also called mutation, is the process of updating the BBMP record so that the municipal body recognises you, the new owner, for property tax and civic purposes. It follows the registration of your sale deed, and for properties registered through the Kaveri system it is increasingly initiated automatically once the buyer and seller complete Aadhaar based verification on the BBMP e-Aasthi portal. The trade off is that it is not truly automatic in every case: you still need clean documents, and a disputed or unclear title can stop the mutation, so a buyer should treat khata transfer as a step to confirm rather than assume.

What is khata transfer, and why must a buyer do it?

Khata transfer is the updating of the municipal ownership record after a sale, and a buyer must do it because the sale deed and the khata answer two different questions. Your registered sale deed proves that you bought the property, while the khata is the record that the BBMP uses to recognise you as the owner for tax and civic dealings. Without the transfer, the property tax continues to be billed in the previous owner's name, and the civic record does not reflect your ownership. That gap matters in practice: municipal and utility processes, and later a clean resale, all rely on the khata showing the right owner. This is why khata transfer should be treated as the natural completion of a purchase, not an optional afterthought that can wait indefinitely.

The HSR Layout example shows the cost of skipping it. Tax notices in the wrong name are only the visible symptom, and the deeper problem is that your ownership is not fully reflected in the record the city trusts. That can surface at the worst moment, when you try to sell and a careful buyer's lawyer notices the khata never moved into your name, or when a bank processing a loan against the property asks why the civic record still shows the previous owner. Closing the loop early avoids these awkward, avoidable delays.

When does khata transfer happen, and what is auto mutation?

Khata transfer happens after your sale deed is registered, and for many recent transactions it is now started automatically through the e-Aasthi system. When a property is registered through the state's Kaveri registration system, the mutation can be initiated without a separate manual application, provided the buyer and seller complete Aadhaar based verification on the BBMP e-Aasthi portal. For a clean title property, the system can then process the mutation with little manual intervention, after a short public objection window during which any competing claim can be raised. This is a genuine improvement over the older process, which required a manual application and a longer wait. The important caveat is that auto mutation depends on the title being clean and the verification being completed, so a buyer should confirm that the mutation actually went through rather than assume the system handled it silently.

What documents do you need for a khata transfer?

You need the documents that prove the sale and the property's tax and record history. In practice these include your registered sale deed, the encumbrance certificate, the latest property tax receipts, and a copy of the previous khata, along with identity proof and, where relevant, an occupancy certificate. You should also make sure the property identification number is consistent across your documents, because a mismatch there is a common reason a mutation stalls. Because the exact list can vary with the property and the route, manual or automatic, confirm the current requirements on the official BBMP e-Aasthi portal and keep clean scans ready. Where the purchase was through the Kaveri system, the Aadhaar based verification of both parties is a key step, so ensure the seller cooperates with their part of the e-KYC.

How do you transfer a khata on the e-Aasthi portal?

You transfer a khata on the official BBMP e-Aasthi portal, which now handles the mutation digitally rather than through a paper file at the ward office. Work through the process in order and keep proof of each step.

1. Open the official BBMP e-Aasthi portal and log in with your mobile number and one time password.
2. Locate the property using its property identification number from the sale deed or previous khata.
3. Choose the khata transfer or mutation option for the property.
4. Upload the registered sale deed, encumbrance certificate, previous khata, and tax receipts.
5. Complete the Aadhaar based verification, ensuring the seller also finishes their part where required.
6. Pay the applicable transfer fee online and note the acknowledgement.
7. Track the application through the objection window and download the updated khata once the mutation is approved.

After approval, check that the updated e-Khata shows your name and the correct property details, and confirm that the next property tax demand is raised in your name rather than the seller's.

What does a khata transfer cost, and how long does it take?

A khata transfer carries a fee and, for a clean case, is now considerably faster than it used to be. The fee is typically calculated in relation to the stamp duty paid on your sale deed rather than being a flat amount, so the exact figure depends on your transaction and should be confirmed on the official portal. On timing, a straightforward, clean title case processed through the automatic route can complete in a fraction of the time the old manual process took, once the verification is done and the short public objection window has passed without a valid objection. More complex cases, or those with a document mismatch or a title question, take longer because they need manual review. Rather than rely on a single number for either fee or timeline, treat the official portal as the source of truth and budget a little buffer for a case that needs extra scrutiny.

Khata transfer versus getting an e-Khata versus a khata extract

These khata related steps are easy to confuse, so here is what each one is.

For background on generating the digital record itself, our separate guide on getting a BBMP e-Khata pairs naturally with this one, since a transfer updates the very record that guide explains.

What should a buyer check to avoid a stuck mutation?

To avoid a stuck mutation, a buyer should check that the title is clean, the property identification number matches across documents, and the seller completes their part of the verification. A disputed title or a competing claim raised during the objection window will stop an automatic mutation and push the case into manual review, so a clean encumbrance certificate and a clear chain of ownership matter here just as they do at purchase. A property identification number that differs between the sale deed and the old khata is a frequent cause of delay, so reconcile it before you apply. Where the deal went through the Kaveri system, make sure the seller does not disappear before completing their Aadhaar based verification, because the transfer can hinge on it. And after approval, confirm the tax demand shifts to your name, which is the real world proof the mutation worked. Sorting these out early turns khata transfer from a lingering worry into a closed step.

Frequently asked questions

What is khata transfer or mutation in Bengaluru?

Khata transfer, or mutation, is the process of updating the BBMP municipal record to show the new owner after a sale, inheritance, or gift. The sale deed proves you bought the property, while the khata is what the BBMP uses to recognise you as owner for tax and civic purposes. It follows registration of the sale deed.

Is khata transfer automatic after registration?

For properties registered through the Kaveri system, the mutation can be initiated automatically once the buyer and seller complete Aadhaar based verification on the BBMP e-Aasthi portal, and a clean title case can be processed with little manual intervention. It is not guaranteed in every case, so a buyer should confirm the mutation actually went through.

What documents are needed for a khata transfer?

You typically need the registered sale deed, the encumbrance certificate, the latest property tax receipts, and a copy of the previous khata, along with identity proof and, where relevant, an occupancy certificate. Ensure the property identification number matches across documents, and confirm the current list on the official BBMP e-Aasthi portal before applying.

How long does a khata transfer take?

A clean title case processed through the automatic route can complete much faster than the old manual process, once the Aadhaar based verification is done and a short public objection window passes without a valid objection. Cases with a document mismatch or a title question take longer because they need manual review. Confirm timelines on the official portal.
