An Encumbrance Certificate (EC) in Tamil Nadu is the registered transaction history of a property — every sale, mortgage, gift, or court attachment recorded at the Sub-Registrar Office. You apply for it online, free, through the TNREGINET portal, or request a certified copy at the SRO. An EC that lists transactions is issued as Form 15; a nil EC is issued as Form 16. Online viewing is instant; a certified copy takes 2–5 working days.

Do not treat the EC as a standalone title certificate. Every entry must be reconciled with original deeds and revenue records.
Current survey and subdivision match Patta, FMB, and sale deed.
Village maps to the SRO that issued the EC.
At least 30 years checked for land purchase diligence.
Every listed document is tied back to a certified copy.
No registered encumbrance found; not proof of clean title by itself.
Every mortgage has a release deed or lender NOC.
Case status is checked before deal approval.
Parties, dates, extent, and document numbers align with legal opinion.
Before applying, match the survey number, subdivision, village, taluk, SRO, extent, and boundary description against the Patta, FMB sketch, and latest sale deed so the EC search covers the correct parcel and period.
For an online EC, register free on the TNREGINET portal and open E-Services → Encumbrance Certificate → Search & Apply. For a certified copy, apply at the Sub-Registrar Office that holds the records. Online viewing is free; a certified copy carries a small per-year fee.
Official PortalSelect the zone, district, and SRO, then the search period — 13 years for a bank loan, 30+ years for full title diligence (TNREGINET computerised records generally cover 1987 onward; older entries may need an SRO visit). Enter the village, survey number, and subdivision, solve the captcha, and download the EC as a free PDF.
An EC with entries is issued as Form 15 — for each sale, mortgage, release, partition, gift, power of attorney, or court attachment, record the document number, date, parties, consideration, and extent. A nil EC is issued as Form 16, meaning no registered encumbrance for the period (not, by itself, proof of clear title).
Every transfer in the advocate title chain should appear in the EC, and every mortgage should have a corresponding release deed or lender NOC.
Unreleased mortgages, court attachments, missing co-owner transfers, mismatched extents, and nil ECs without supporting title documents need legal review before payment.
Reliability comes only when the EC is reconciled with deed, revenue, and survey records.
| Document | Verification Purpose |
|---|---|
| Encumbrance Certificate | Registered transaction history and encumbrances for a period. |
| Sale deed | The actual ownership-transfer instrument. EC entries must point back to it. |
| Patta / Chitta | Revenue ownership record; useful but not proof of marketable title by itself. |
| A-Register | Village land register every Patta is drawn from; confirms classification and the canonical owner record. |
| FMB sketch | Survey boundary and subdivision reference used to catch wrong-survey EC searches. |

Viewing and downloading the EC online via TNREGINET is free and instant.
A certified copy is charged per year of the search period (roughly a ₹1 application fee, ₹15 for the first year, and ₹5 for each additional year, plus a computerised-records charge for entries from 1987 onwards) and typically takes 2–5 working days from the Sub-Registrar Office.
An Encumbrance Certificate shows registered transactions against a property for a selected period, including sale deeds, mortgages, releases, partitions, gifts, powers of attorney, and court attachments recorded at the relevant Sub-Registrar Office.
It does not show every possible risk. Unregistered agreements, oral family arrangements, some equitable mortgages, government acquisition notifications, and pending litigation may not appear.
No. A nil EC, called Form 16 in Tamil Nadu, means no registered encumbrance was found for the requested property and period.
Clear title still requires Patta or revenue-record verification, original sale-deed review, FMB or survey verification, tax records, court checks, and an advocate title opinion.
For land purchases, a 30-year EC is the practical minimum used by many legal teams. Older or inherited properties may need a longer search if the title chain depends on older documents.
If the seller provides only a shorter EC, request the full period yourself from the registration portal or SRO.
The highest-risk flags are an unreleased mortgage, a court attachment, a sale deed to a third party, a missing co-owner transfer after partition, or a property extent that does not match the sale deed and FMB sketch.
Each red flag should be resolved with source documents before token advance or sale-agreement execution.
Yes. Some equitable mortgages may not appear in the EC depending on how the security was created and recorded.
For higher-value land deals, also check lender NOCs and CERSAI records instead of relying only on the EC.
