What Is the Difference Between EC Form 15 vs Form 16?
The main difference is simple: Form 15 contains registered transaction entries, while Form 16 records a nil result for the period searched.
Feature | Form 15 | Form 16 |
EC result | Transactions found | No transactions found |
Record | Shows registered entries | Shows a nil result |
Common information | Document details, dates and transaction records | No transaction entries for the searched period |
Main purpose | Reviewing registered transaction history | Confirming that no registered transactions were found for that period |
Interpretation | Requires checking the listed transactions | Requires checking whether the nil result is expected |
The distinction matters because the two forms tell you different things about the registration records searched.
For example, if a property was sold in 2019 and the sale deed was registered, that transaction may appear in a Form 15 when the search period covers the registration date. If the same property has no registered transaction during another selected period, the EC search can return Form 16 for that period.
The BBMP Revenue Department specifically lists an Encumbrance Certificate in Form 15 among the documents required for several Khata services. For example, its Khata transfer requirements call for Form 15 from the date of the sale deed to the current date. This shows why Form 15 can contain a useful record of registered transactions rather than being treated as a negative result.
So, don't read the two forms as “good” versus “bad.” Read them as “transactions found” versus “no transactions found during the searched period.”

What Does Form 15 Show in an EC?
Form 15 shows the registered transactions found against the property for the period covered by the EC search. The entries can help you compare the property's registration history with the documents provided by the owner.
A Form 15 may contain information connected with registered dealings such as:
Sale transactions
Mortgage registrations
Release of mortgage
Gift or settlement transactions
Partition or release-related registrations
Registration numbers and dates
Names of parties connected with the registered document
The exact entries depend on what has been registered and falls within the search parameters.
Consider a Bengaluru property purchased with a bank loan. The EC may show the sale transaction followed by a registered mortgage. If the loan is later cleared and the required release document is registered, that transaction may also form part of the property's registered history.
A transaction appearing in Form 15 therefore does not automatically mean that the property currently carries that liability. A buyer needs to read the entry along with the relevant registered document and its later entries.
The BBMP Revenue Department's Khatha documentation requirements provide a practical example. For Khatha transfer through sale, it asks for Form 15 covering the period from the sale deed to the current date. For Khatha registration, it also specifies Form 15 up to the month of application in several property categories.
This makes the date range particularly important. A Form 15 covering 2018–2026 and an EC covering only 2025–2026 are not answering the same question.
Before relying on a Form 15, compare the entries with the property's sale deed and other registered documents. If a mortgage appears, check whether a later release entry or supporting document exists before assuming the loan is still outstanding.
What Does Form 16 Mean in an EC?
Form 16 means that no registered transactions were found for the property during the period covered by the EC search. It is commonly described as a nil Encumbrance Certificate.
A Form 16 can be perfectly normal when the searched period contains no registered transaction. For example, if a property had no registered sale, mortgage, gift, release or other recorded transaction during the selected period, the search can return a nil result.
The important point is the phrase “during the searched period.”
Form 16 does not mean that the property has never been sold, mortgaged or transferred. It only tells you that the EC search did not find a registered transaction within the period and property details used for that search.
This distinction becomes important with older properties.
Suppose a Bengaluru flat was purchased in 2017, but an EC is searched for a period that does not include the relevant earlier registration. A nil result for that shorter period cannot be used to establish the property's entire registration history.
The same issue can arise if the wrong property identifier is used during the search. A buyer should compare the details used for the EC with the sale deed and other property records before treating a Form 16 as confirmation of a clean history.
The Greater Bengaluru Authority currently provides e-Aasthi and other property-related e-services through its official portal. For Bengaluru properties, the EC should be considered alongside the relevant municipal and title records rather than as a standalone ownership document.
A Form 16 is therefore best understood as a nil search result, not as a certificate saying that every possible legal issue connected with the property has been ruled out.

How Should You Read EC Form 15 vs Form 16 Before Buying Property?
Start by checking the property details and search period, then compare the EC result with the property's registered documents. The following four checks can help you understand whether the Form 15 or Form 16 you received matches the property history.
Check the Property Details
First, compare the property information used for the EC search with the details in the sale deed and other title documents.
Check details such as the survey number, subdivision details and other identifiers applicable to the property. For a Bengaluru urban property, also compare the municipal property information where relevant.
A mismatch can make an EC result difficult to rely on. If an older property unexpectedly produces Form 16, don't immediately treat the nil result as proof that there are no earlier registered transactions.
Check the Search Period
Next, look at the exact period covered by the EC.
A Form 15 for 2018–2026 contains a different search history from a Form 16 covering only 2025–2026. The latter does not erase transactions registered before 2025.
The BBMP Revenue Department uses specific periods in its Khatha documentation requirements, including Form 15 from the sale deed date to the current date in several situations. That makes the start and end dates a key part of interpreting the certificate.
Match Form 15 Entries With Documents
If you receive Form 15, compare each relevant entry with the documents available for the property.
For example, if the EC contains a sale transaction, check whether the sale deed has the same registration details. If a mortgage appears, check the related mortgage document and look for a later registered release where applicable.
Don't treat the number of entries as the deciding factor. An older property can have several legitimate registration entries because ownership and financing have changed over time.
Investigate an Unexpected Form 16
If an older property returns Form 16 despite having a known sale history, verify the search before relying on the result.
Recheck the property identifiers and search period. Then compare the result with the sale deed and other registered records available for the property.
A nil EC can be useful when it matches the expected history. It needs further checking when it contradicts documents that you already know exist.
How Vault Helps with EC Form 15 vs Form 16
Vault Proptech helps property owners and buyers obtain and understand their Encumbrance Certificate, including whether the result is Form 15 or Form 16.
The service is useful when you aren't sure which property details to use, what search period to select, or how to read the result returned for a Karnataka property.
For buyers, the focus is on understanding the EC record before proceeding with property documentation. For NRIs and out-of-station owners, professional assistance can also help reduce the need to handle Karnataka property documentation entirely on their own.
The EC result can then be considered alongside the property's sale deed and other relevant records. If the EC returns Form 15, the registered entries can be reviewed against the available documents. If it returns Form 16, the nil result can be checked against the property's known history and search details.
