The Encumbrance Certificate is the record of every transaction registered against a property at the Sub-Registrar's office. In Karnataka it is issued through Kaveri Online Services, and for most buyers it is the single most useful document in the file — it is where an undisclosed mortgage shows up.
It is also the document most often misread. A clean EC is not proof of clean title. It covers only registered transactions, only for the period you searched, and only at the office you searched. The gaps are structural, they are well known to anyone who does this professionally, and they are almost never explained to buyers. This guide covers how to obtain the certificate and, more importantly, how to read what is missing from it.
How to get an EC from Kaveri Online
- 1Open Kaveri Online Services, the Karnataka Department of Stamps and Registration portal, and register as a citizen user or log in.
- 2From the services menu choose the Encumbrance Certificate search.
- 3Enter the property identifiers — district, taluk, village or the relevant Sub-Registrar Office, and the survey number or property number. Take these from the current RTC or the sale deed, not from memory.
- 4Set the search period. For a purchase, search at least 15 years; 30 years is the standard due-diligence window because it covers the limitation period for most adverse claims.
- 5Choose the copy type. The free information copy is available after OTP verification and is watermarked for information only. The digitally signed certified copy requires an application and the prescribed fee.
- 6Pay and submit. The certified copy is processed by the office and released to your login dashboard, typically within a few working days.
- 7Download and check the property description on the certificate matches the property you are buying — not just the survey number, but the extent and the boundaries recited.
The free information copy is rejected by banks and generally by Sub-Registrars. If the EC is for a loan or a registration, apply for the digitally signed copy and allow for the processing days.
Form 15 and Form 16: what the two outputs mean
| Output | What it means | How to read it |
|---|---|---|
| Form 15 | Registered transactions were found in the period searched | Read every entry — sale, mortgage, gift, release, partition — in date order |
| Form 16 (Nil EC) | No registered transactions found in that period at that office | Not a clean chit. It means nothing was registered in that window, there |
A Nil EC is the most misunderstood document in Indian property diligence. Buyers treat it as confirmation the property is unencumbered. It is nothing of the sort — it is a statement about a period and an office. If the mortgage was created in year eleven and you searched ten years, you get a Nil EC on a mortgaged property, and the certificate is entirely accurate.
When you get a Nil EC, widen the period before you relax. If a property genuinely changed hands in living memory, a 30-year search should show something. A Nil EC over 30 years on a property with an obvious transaction history means you searched the wrong identifier or the wrong office.
The pre-2004 blind spot
Kaveri holds digitised registration records from roughly April 2004 onward. Anything earlier is not online. This is the single largest gap in Karnataka property diligence and it is rarely stated plainly.
It matters because title defects are usually old. A disputed partition from the 1980s, an unregistered agreement from the 1990s, a grant-land sale in breach of its non-alienation condition — none of that appears in an online EC starting at 2004. The online certificate tells you the property has been quiet for twenty years. It does not tell you how it became the seller's in the first place.
- For any purchase of consequence, get a manual search of the register at the Sub-Registrar office for the pre-2004 period.
- Read the Mutation Register alongside the EC. Inheritance and partition transfers never reach the Sub-Registrar at all, so they are invisible to any EC of any period — but they appear in the revenue records and often go back much further.
- Where the chain enters via a government grant or inam, trace the original grant order. That is the root of title and it is not in either system.
Five things the EC will never show you
The certificate is a register of registered instruments. Anything that was never registered is outside its scope by definition.
- Unregistered agreements to sell. Common, enforceable in various ways, and completely invisible here.
- Oral partitions within a family. Widespread in agricultural land, and a frequent source of a sibling appearing years later with a claim.
- Inheritance and succession. These pass by operation of law, are recorded by mutation in the revenue records, and never touch the Sub-Registrar.
- Tax dues and municipal liabilities. Property tax arrears attach to the property and pass to you. Check E-Aasthi for urban property.
- Pending litigation and court attachments. Some attachments are registered and appear; many disputes do not. Check the revenue court records and, for anything significant, run a court-record search on the parties.
The Supreme Court has held that registration does not by itself prove ownership. An EC proves what was registered. Ownership is established by reading the EC, the RTC, the Mutation Register and the underlying deeds together, and by tracing the chain back to a root.
How to actually read a Form 15
Do not skim for the word "mortgage". Read the entries as a sequence and look for the joins that are missing.
- 1Put every entry in date order and write down the parties on each. You are reconstructing a chain, not auditing a list.
- 2Check that each transfer out matches a transfer in. If A sells to B, the next entry involving the property should have B as the transferor. A jump from A to C with no A-to-B-to-C trail is a gap that needs explaining.
- 3Find every mortgage and then find its release. A mortgage entry with no corresponding release deed means the charge is very likely still live, whatever the seller says.
- 4Check the extent recited in each deed. An extent that shrinks or grows mid-chain usually means a partition or sub-division that may not have been recorded properly.
- 5Note any release, relinquishment or partition deed. These tell you a family had competing claims that were settled — and who was left out.
- 6Compare the final owner on the EC against the current owner on the RTC. If they differ, one of the two systems was never updated, and you need to find out which.
A registered sale deed with no corresponding mutation in the revenue records means the buyer paid but never took revenue possession. That mismatch is one of the most reliable early indicators of a problem property.
Frequently asked questions
How many years of Encumbrance Certificate should I get before buying?
At minimum 15 years. For any significant purchase, 30 years is the standard, because it covers the limitation period for most adverse claims. Note that the online record generally starts around April 2004, so a 30-year search will need a manual search at the Sub-Registrar office for the earlier part.
What is the difference between Form 15 and Form 16?
Form 15 is issued when registered transactions were found in the period searched and lists them. Form 16, often called a Nil EC, is issued when no registered transactions were found. Form 16 is not a certificate of clean title — it only states that nothing was registered in that window at that office.
Is a Nil EC good news?
Not on its own. It is a statement about a specific period and a specific Sub-Registrar office. A mortgage created outside the period you searched produces a perfectly accurate Nil EC on an encumbered property. Widen the search period before drawing conclusions.
Can I get an Encumbrance Certificate for the period before 2004?
Not through the online portal. Kaveri holds digitised records from around April 2004. Earlier periods require a manual search of the register at the relevant Sub-Registrar office. This matters, because older title defects are precisely the ones that do not appear online.
Does a clean EC mean the property has clear title?
No. The EC covers registered transactions only. Unregistered agreements, oral partitions, inheritance, tax dues and much pending litigation never appear on it. Read the EC together with the RTC, the Mutation Register and the underlying deeds, and trace the chain to its root.
Is the free EC from Kaveri accepted by banks?
No. The free copy is an information copy, watermarked and marked as not legally valid. For a home loan or a registration you need the digitally signed certified copy, which requires an application and the prescribed fee and takes a few working days to issue.
The EC shows a mortgage but the seller says it is repaid. What do I do?
Ask for the registered release deed and find it on the EC yourself. A repaid loan should produce a release entry. If the loan was repaid but the release was never registered, the charge remains on record and must be cleared before you complete the purchase — not after.
