How to Read an Encumbrance Certificate (EC) Tamil Nadu — Explained Simply
You applied for an Encumbrance Certificate on TNREGINET, downloaded the PDF, and now you're staring at a table full of numbers, dates, and document names — wondering what any of it actually means.
You are not alone. Most first-time property buyers in Tamil Nadu get the EC because their bank asked for it, but have no idea how to read it. This guide walks through every part of a Tamil Nadu EC document — what each section means, how to spot red flags, and what a completely clean EC looks like.
All steps in this guide are performed on the official Tamil Nadu government portal.

Two Types of EC in Tamil Nadu
Before reading the EC, you need to know which type you have — because they look different:
| Type | Form | When It Is Issued | What It Shows |
|---|---|---|---|
| Form 15 EC | Form 15 | When transactions exist on the property during the requested period | A table of all registered documents — sales, mortgages, gifts, etc. |
| Form 16 EC (Nil EC) | Form 16 | When NO transactions are found for the requested period | A statement that no encumbrances were found for the period |
A Form 16 (Nil EC) is actually good news for a specific period — it means nothing was registered against the property during those years. Many buyers panic when they see Form 16, thinking something is wrong. It is not.
The Header Section of the EC
The top part of every EC contains property identification details. Here is what each field means:
- EC Reference Number — The unique ID of this EC document. Used to verify authenticity at TNREGINET.
- SRO Name — The Sub-Registrar Office where documents were registered. Must match the property's location.
- Village / Taluk / District — Administrative location of the property.
- Survey Number / Sub-division — The land parcel identifier. Verify this matches your property's Patta Chitta record exactly.
- Period (From Date to To Date) — The years covered by this EC. Banks ask for minimum 13 years.
- Date of Issue — When the EC was generated. Banks treat ECs older than 6 months as stale.
The Transaction Table — Column by Column
The main body of a Form 15 EC is a table with rows for each registered transaction. Here is what each column means:
Column 1 — Serial Number (S.No.)
Just the row number. Transactions are listed in chronological order — oldest first. The number itself has no significance.
Column 2 — Document Number and Year
This is the registration number assigned by the SRO when the document was registered. Format is typically a number followed by the year — for example, 1245/2019. You can use this number to retrieve the original document from the SRO if needed.
Column 3 — Nature of Document
This is the most important column. It tells you what type of transaction occurred. Common entries and what they mean:
| Nature of Document | What It Means | Good or Concern? |
|---|---|---|
| Sale Deed / Absolute Sale | Property was sold from one owner to another | 🟢 Normal — check the chain of sellers and buyers |
| Gift Deed / Settlement Deed | Property was transferred as gift, often within family | 🟢 Normal |
| Partition Deed | Joint property was divided among co-owners | 🟢 Normal — verify shares are correctly assigned |
| Simple Mortgage Deed | Owner borrowed money using property as registered security | 🔴 Check if discharged |
| Memorandum of Deposit of Title Deed / MODT | Bank holds original title deed for a home loan | 🔴 Check if discharged |
| Discharge of Mortgage | A previous mortgage has been fully repaid and released | 🟢 Good — confirms loan cleared |
| Release Deed | A co-owner releases their share to another party | 🟢 Normal — verify parties |
| Rectification Deed | A correction was made to a previously registered document | 🟡 Neutral — read what was corrected |
| Court Attachment / Prohibitory Order | Court has frozen the property from being sold | 🔴 Very serious — do not buy without legal advice |
| Agreement to Sell | A sale agreement (not the actual deed) was registered | 🟡 Check if the sale was completed |
| Power of Attorney | Owner gave someone authority to act on their behalf | 🟡 Check scope and current validity |
Column 4 — Executant (Party 1)
The person who is giving/transferring/mortgaging. In a sale deed, this is the seller. In a mortgage, this is the borrower (property owner). Verify that the executant's name in each row matches logically — the buyer in one sale should appear as the seller in the next.
Column 5 — Claimant (Party 2)
The person receiving the benefit. In a sale deed, this is the buyer. In a mortgage, this is the bank or lender. In a gift deed, this is the recipient.
Column 6 — Property Description
The land details — survey number, area, boundaries. Verify this matches the property you are buying. If the survey number in the EC doesn't match your Patta Chitta, something is wrong.
Column 7 — Consideration Amount
The value declared for this transaction. For mortgages, this is the loan amount. For sales, this is the declared sale price. Note that declared values are often lower than actual market value in older transactions.
How to Read the Chain of Title
Reading the EC is really about reading the story of the property. Start from the first row and trace forward:
- Who originally owned the property during your EC period?
- Who did they sell it to? (Look for a Sale Deed row where the original owner is the Executant)
- Did the new owner take a loan? (Look for a Mortgage entry where the new owner is the Executant)
- Was that loan discharged? (Look for a Discharge of Mortgage entry from the bank)
- Was it sold again? And again?
- Does the last buyer in the EC match who is currently claiming to sell it to you?
Every step in this chain should connect logically. If there are gaps — someone selling who was never shown as a buyer — investigate.
What a Completely Clean EC Looks Like
A clean EC for a residential property might look like this:
| Row | Document | Executant | Claimant | Notes |
|---|---|---|---|---|
| 1 | Sale Deed 2005 | Rajan (original owner) | Senthil (your seller) | ✅ Clean sale |
| 2 | Simple Mortgage 2010 | Senthil (borrower) | SBI Bank (lender) | ⚠️ Loan taken — check row 3 |
| 3 | Discharge of Mortgage 2018 | SBI Bank | Senthil | ✅ Loan fully repaid |
This EC is clean. There was a loan, but it was repaid and discharged. The chain is clear — Rajan sold to Senthil, Senthil took a loan, the loan was repaid. Senthil is now selling to you with no active encumbrances.
Red Flags to Watch For
- 🔴 Mortgage with no discharge — Active loan, must be cleared before purchase
- 🔴 Court attachment — Legal freeze on property, cannot be sold
- 🔴 Gap in ownership chain — Someone selling who was never shown as a buyer
- 🔴 Survey number mismatch — EC property description doesn't match Patta
- 🟡 Registered Agreement to Sell to a third party — Was this sale completed? Check
- 🟡 Power of Attorney — Is it still valid? Has it been revoked?
Frequently Asked Questions
What is Form 16 EC and is it bad?
Form 16 is a Nil Encumbrance Certificate — it means no transactions were registered on the property during the period you searched. This is not bad. It could simply mean the property was not sold, mortgaged, or involved in any registered transaction during those years. Verify the property's history outside that period too.
My EC shows the property description is slightly different from the Patta. What should I do?
Small differences in wording are common. But if the survey number or sub-division number is different, investigate. It could mean the EC is for a different sub-division. Consult a property lawyer or the SRO to clarify before proceeding.
How do I know if the EC is authentic and not forged?
Every certified EC downloaded from TNREGINET has a Reference Number and Authentication Code. Go to tnreginet.gov.in → Verify EC → enter these two values. If the document is genuine, the portal will confirm it. You can also scan the QR code on any page of the certified EC.
Does the free EC view show the same information as the paid certified EC?
Yes — the transaction data is the same. The difference is that the paid certified EC carries the Sub-Registrar's digital signature and QR code, making it legally valid for submission to banks, courts, and registration offices. The free view is for reference only.
