Before you pay an advance on a plot or house anywhere in Karnataka, someone will ask for the Encumbrance Certificate, or EC. It is a short document, but it answers a question every buyer needs answered: has anything been registered against this property over the years — a sale, a mortgage, a gift, a lease? This guide explains what an EC shows, the difference between Form 15 and Form 16, how to apply through the Kaveri online system or at the sub-registrar office, how long a period to search, and — just as important — what an EC does not show. It is general information, not legal advice; your property lawyer should always read the EC alongside the title documents.
What an Encumbrance Certificate actually is
An encumbrance is any claim or charge on a property — a mortgage to a bank, a registered lease, a registered agreement, or a sale that moved ownership from one person to another. The Encumbrance Certificate is an extract from the records of the sub-registrar office, the government office where property documents are registered. It lists the registered transactions involving a particular property during the period you ask about.
For each transaction, the EC typically records the document's registration number and date, the type of document (sale deed, mortgage, release, gift, partition and so on), the parties to it, and a short description of the property. Read together, those entries give you a timeline of what has happened to the property on paper.
That timeline is valuable for two reasons. First, it lets your lawyer check that ownership has passed cleanly from one owner to the next, with no missing link, up to the person now selling. Second, it reveals registered liabilities — most often a mortgage in favour of a bank — that the seller would need to clear before selling to you.
Keep one limit in mind from the start: the EC only knows about documents that were registered. Anything that never passed through a sub-registrar office is invisible to it. That is why the EC is one important check among several, not a certificate that the property is free of every problem.
Form 15 and Form 16: what the difference means
In Karnataka, the EC comes in one of two forms, and the form number alone tells you something.
- Form 15 is issued when the records show one or more registered transactions for the property during the period searched. It lists each of them.
- Form 16 is issued when no registered transaction is found for that period. It is often called a nil encumbrance certificate.
A common misunderstanding is that Form 16 is the good one and Form 15 is a warning. That is not how it works. Any property that was bought and sold during the search period will show those sales, so a Form 15 is normal and often expected. What matters is what the entries say. A Form 15 listing a clean chain of sale deeds — and perhaps a mortgage followed by a registered release when the loan was repaid — can be perfectly healthy.
Equally, a Form 16 is not automatically reassuring. If the seller says they bought the site some years ago but the EC for that period shows nothing at all, something does not add up. The property details on the application may be wrong, the search may have been made in the wrong sub-registrar office, or the seller's account may not match the records. Your lawyer should find out why before you go further.
How to apply: Kaveri online or the sub-registrar office
Karnataka's property registration runs on the Kaveri online system, and at the time of writing (2026) you can apply for an EC through it: you enter the property details and the period you want searched, pay the fee online, and receive the certificate once it is issued. You can also apply in person at the sub-registrar office that has jurisdiction over the property.
Either way, have these details ready before you start:
- The property's identifying details exactly as they appear in the title deed — survey number, site or house number, layout name, village or ward.
- The sub-registrar office the property falls under today, and any office it came under in the past.
- The period you want searched, from a start date to an end date.
- A copy of the seller's title deed, so you can match every detail.
Two practical points trip people up. First, older records may not all be digitised, so for earlier years the office may need to search its manual registers — ask how this is handled when you apply. Second, sub-registrar jurisdictions have been redrawn over time as towns and cities grew, so a property may have come under a different office in the past. An EC from only the current office could miss older entries.
The fee depends on the period searched and can change, so check the current amount on Kaveri or at the office. Processing time also varies, so apply early enough that it does not hold up your purchase.
How far back should the EC go?
The EC covers only the period you ask for, so choosing that period is a real decision, not a formality. A short search covering just the last few years tells you very little. If a mortgage was registered long ago and never discharged, or an earlier sale in the chain was irregular, a short EC will simply not show it.
For this reason, property lawyers commonly ask for a long period — often looking back several decades — so that the EC covers the whole chain of title they are examining, not only the seller's own time as owner. There is no single right number of years for every property; it depends on the property's history and on how far back its ownership documents go.
A sensible approach:
- Collect the seller's title deed and the earlier deeds in the chain, going back to the mother deed where possible — the oldest document from which the current ownership flows.
- Ask your lawyer to set the EC period so that it covers that whole chain.
- Make sure the period runs right up to a recent date.
- Get a fresh EC shortly before registration, so that nothing registered in the meantime slips through.
A transaction registered between your first EC and registration day is exactly the surprise you want to catch while you can still walk away.
What an EC does not show
Because the EC is built only from registered documents, a clean EC can still sit alongside serious problems. Know its blind spots so that you can cover them in other ways:
- Unregistered agreements. A sale agreement the seller signed with someone else will not appear if it was never registered.
- Some court cases. A pending suit over the property — a partition claim by a relative, a boundary dispute, a challenge to an earlier sale — may leave no trace on the EC.
- Informally secured loans. Where a lender simply holds the original title deeds as security, the loan may not show up. This is one reason to insist on seeing the originals, not photocopies.
- Inheritance. When property passes to heirs by succession, there may be no registered document at all, so ownership can change without an EC entry.
- Dues and government action. Unpaid property tax, planning violations or government proceedings over the land are recorded elsewhere, if at all.
To cover these gaps, your lawyer will typically look at the khata or e-Khata and tax receipts, the land records for converted agricultural land, and sometimes court records.

Cross-checking the EC against the title documents
An EC is only as useful as the reading it gets. Here is what a careful review looks for:
- Every entry has a document. Each sale, gift, release or partition on the EC should match a deed in the chain of title you have been given. If the EC lists a transaction you have not seen, ask for it — a certified copy of a registered document can be obtained from the sub-registrar office.
- Every deed has an entry. The reverse check matters too. A registered deed the seller shows you that does not appear on the EC needs explaining.
- Mortgages are closed. If a mortgage appears, look for a later registered release and a no-dues letter from the lender. An open mortgage must be cleared before or at the sale.
- Details match. Names, survey or site numbers, measurements and boundaries should agree across the EC, the deeds and the khata or e-Khata. Small spelling differences are common but still worth clarifying in writing.
- The chain ends with the seller. The last ownership entry should lead to the person selling to you.
After you buy, the EC becomes your record too. Once your sale deed is registered, a fresh EC a little later should show it — worth checking, and worth filing with your papers.

Frequently asked questions
- Is Form 15 or Form 16 better when buying property?
- Neither is better in itself. Form 16, the nil encumbrance certificate, means no registered transaction was found in the period searched; Form 15 lists the transactions that were found. A property that changed hands during the period will naturally have a Form 15. What matters is whether the entries form a clean chain of ownership and whether any mortgage shown has been released. A Form 16 that contradicts the seller's own history is a reason to ask questions.
- Can I get an Encumbrance Certificate online in Karnataka?
- Yes. At the time of writing, you can apply for an EC through Karnataka's Kaveri online system by entering the property details and the period to be searched, and paying the fee online. You can also apply at the sub-registrar office with jurisdiction over the property. Check the current fee and process on Kaveri when you apply.
- How many years should an Encumbrance Certificate cover?
- There is no single fixed answer. The EC only covers the period you request, so a short search can miss an old mortgage or an irregular earlier sale. Property lawyers commonly look back several decades so that the EC covers the whole chain of title, and lenders set their own requirements. Ask your lawyer to fix the period for your particular property, and make sure it runs up to a recent date.
- Does a clean EC mean the property is free of problems?
- No. An EC shows only documents registered with the sub-registrar. Unregistered sale agreements, many court cases, loans secured by simply handing over the original deeds, and changes of ownership by inheritance may not appear on it. A clean EC is a good sign, but your lawyer should also check the title deeds, the khata or e-Khata, tax receipts and, where relevant, land and court records.
- Should I rely on the EC the seller gives me?
- It is safer to get your own, or have your lawyer get it. A copy handed over by the seller may be old, may cover too short a period, or in rare cases may not be genuine. Applying yourself through Kaveri or the sub-registrar office lets you choose the period, confirm the property details match the deeds, and be sure the certificate is current. Get another fresh one shortly before registration.
