How to Check Patta and Chitta Land Records Online in Tamil Nadu (and the EC on TNREGINET)

TL;DR

• In Tamil Nadu, Patta (the ownership/revenue record) and Chitta (land classification) are now merged into one record you can view free on the Revenue Department's e-Services portal (eservices.tn.gov.in) by district + taluk + village + survey number or patta number; the Encumbrance Certificate (EC) lives separately on the Registration Department's TNREGINET portal (tnreginet.gov.in).
• On TNREGINET, a Form 15 EC lists the registered transactions on a property (sales, mortgages, gifts, partitions); a Form 16 EC is a "nil" certificate meaning no registered encumbrance was found in the period you searched.
• Patta/Chitta and the EC are revenue and registration records — exactly like Karnataka's RTC, they are strong supporting evidence but not standalone proof of clear title. You still trace deeds, check classification, and look for litigation.
• Online EC data typically goes back to around the late 1980s (when registration was computerised); anything older usually means a manual search at the Sub-Registrar Office (SRO).
• The free portals confirm what the government records say today; a proper Title Search Report layers a 30-year deed chain, classification checks, encumbrance sweeps and litigation searches on top, reviewed and signed by a lawyer.

How do I check Patta, Chitta and the Encumbrance Certificate online in Tamil Nadu?

You use two different state portals. Patta and Chitta (now a single merged record) and the related Adangal, A-Register, FMB and TSLR are on the Revenue Department's e-Services site, eservices.tn.gov.in. The Encumbrance Certificate is on the Registration Department's site, tnreginet.gov.in. Both are free to view; the EC can also be applied for as a certified copy.

This mirrors the pattern in every Indian state: one system holds the revenue/land record (who the government taxes for the land and how it is classified) and another holds the registration record (what deeds have actually been registered against it). In Karnataka those are Bhoomi and Kaveri; in Maharashtra they are the 7/12 and the Sub-Registrar; in Tamil Nadu they are e-Services (Patta/Chitta) and TNREGINET (EC).

What is Patta, and what is Chitta?

A Patta is a revenue record that names the legal owner (patta-holder) of a specific parcel, with a unique patta number, the district/taluk/village, the survey number and subdivision, the extent (area), and tax details. A Chitta historically recorded the classification of that land — chiefly whether it is Nanjai (wetland) or Punjai (dryland), which matters for valuation, water rights and what you can build.

Around 2015 the Tamil Nadu government merged Patta and Chitta into a single digital record, so when you pull a "Patta" today it already carries the classification detail. You will still hear both names used out of habit, and lenders and offices still ask for "Patta Chitta" together.

Step-by-step: view the merged Patta/Chitta on e-Services

The same portal also serves the Adangal (the cultivation/crop register, broadly the Tamil Nadu equivalent of the RTC's land-use detail), the A-Register extract (survey-wise ownership, classification and extent maintained at the village level), the FMB (Field Measurement Book sketch showing the parcel's shape and boundaries), and the TSLR (Town Survey Land Register for urban land). The FMB sketch is especially useful for spotting whether the physical parcel matches the survey record before you commission a ground survey.

Step-by-step: view or apply for the EC on TNREGINET

The Encumbrance Certificate — called Villangam in Tamil — is the registration department's statement of what deeds are on record against a property for a chosen date range.

1. Open tnreginet.gov.in. To view an EC you can use the "Encumbrance Certificate then View EC" option; to get a certified copy, register/login and use "Apply Online then Encumbrance Certificate".
2. Choose the search basis: by zone, district, sub-registrar office (SRO), village and survey/subdivision number, or by document number, or (where supported) by the property's new street/door details.
3. Set the period you want searched (for diligence, search as far back as the portal allows, and separately cover the years the online record cannot reach).
4. Submit, pay the small statutory fee if you are requesting a certified copy, and download the result.

If transactions exist in that window you get a Form 15 EC listing them in order — typically the document number and date, nature of the deed (sale, mortgage, gift, settlement, partition, release), parties, consideration and the survey reference. If nothing is found, you get a Form 16 EC, a nil certificate.

What does an EC on Form 15 actually show, and what is Form 16?

A Form 15 EC lists the registered transactions against the property for the period searched — it is your encumbrance and ownership-movement trail. A Form 16 EC is a nil certificate: it states that no registered transaction or encumbrance was found for the property in that period. Both are valid outputs of the same search; which one you receive simply depends on whether the registry has records for your survey number and window.

Read Form 15 the way a diligence team reads a Kaveri EC in Karnataka: every mortgage entry without a matching release deed is a live red flag, the order of sale deeds should form an unbroken chain, and a "settlement" or "release" inside the family can change who actually holds the parcel today. A clean Form 16 is reassuring but, as we cover below, far from conclusive.

For a deeper treatment of why a nil EC is not the same as clear title, see what an Encumbrance Certificate does NOT show.

Are Patta, Chitta and the EC proof of clear title?

No. Like the Karnataka RTC, the Tamil Nadu Patta/Chitta is a revenue record — it reflects who the government holds responsible for the land and how it is classified, not a guaranteed adjudication of ownership. The EC is a registration record — it reflects what was registered, not the legal validity of those deeds. Neither is, on its own, a title.

This is the single most misunderstood point for buyers in any state. A person can hold a patta and still not have good title (the patta could have been mutated on a defective or fraudulent transfer). A property can show a clean EC and still be disputed (over an unregistered claim, an inheritance, or a court order). Title in India is established by tracing a chain of properly executed and registered deeds over time and testing it against classification, encumbrance and litigation records — which is exactly what a Title Search Report sets out to do.

What these Tamil Nadu records cannot tell you

The free portals are genuinely useful, but be honest about their limits:

• Online EC has a time floor. Computerised registration data in Tamil Nadu generally reaches back to around the late 1980s. Transactions older than the digitised period — and a full 30-year chain often needs them — usually require a manual search at the SRO. A short online EC can miss an old mortgage or sale.
• The EC only contains registered documents. Unregistered agreements to sell, oral family arrangements, powers of attorney that were never registered, and unregistered leases will not appear, yet they can still create disputes.
• Patta/Chitta does not vouch for the deed chain. It will not tell you whether the seller's purchase deed was valid, whether an earlier sale was forged, or whether a minor's or co-owner's share was ignored.
• Classification and land-use restrictions need separate checks. Nanjai/Punjai status, conversion for non-agricultural use, CRZ/water-body proximity, and local planning (DTCP/CMDA) approvals are not all visible from a Patta pull.
• Litigation is invisible here. Pending civil suits, partition disputes, or government acquisition will not show on Patta/Chitta or on a standard EC — those need eCourts and High Court searches.
• Data-entry and survey mismatches happen. Names, extents and subdivisions can be mis-recorded; the FMB sketch and a physical survey are how you catch a parcel that does not match its record.

How does the Tamil Nadu workflow compare to other states?

The roles are identical across states — only the portals and document names change. If you already know one state's system, the others map cleanly.

Pan-India concepts that always transfer: the revenue record is not title, the EC only covers registered deeds, you need a 30-year chain, and classification plus litigation are separate searches. For neighbouring playbooks, see Bhoomi RTC for Karnataka, how to download a 7/12 (Satbara) extract in Maharashtra, and the Dharani / Bhu Bharathi records in Telangana.

Where this fits in a real diligence

Pulling the Patta and an EC is step one, not the whole job. A buyer or developer should fold these into a structured process that also covers the deed chain, conversions, planning approvals and litigation — the developer's property due diligence checklist lays out the full sequence. This is also where an automated platform helps: Deedwise gathers the revenue record, the EC, classification and litigation signals across portals, translates and structures them, and flags inconsistencies — then a lawyer reviews and signs the final report. The software does the gathering and drafting; the legal opinion stays human.

Frequently asked questions

Is checking Patta and Chitta online in Tamil Nadu free? Yes. Viewing the merged Patta/Chitta, Adangal, A-Register, FMB and TSLR on the Revenue Department's e-Services portal (eservices.tn.gov.in) is free and needs no login. You can also apply for a certified Patta transfer or correction, which carries a fee. Viewing an EC on TNREGINET is free; a certified-copy EC carries a small statutory fee that varies with the number of years searched.

What is the difference between Form 15 and Form 16 on TNREGINET? Form 15 is an Encumbrance Certificate that lists the registered transactions on a property for the period searched — sales, mortgages, gifts, settlements, partitions and releases. Form 16 is a "nil" Encumbrance Certificate, issued when no registered transaction or encumbrance is found for that property and period. You receive one or the other based on what the registry holds.

Is Patta proof that I own the land? No. A Patta is a revenue record showing who the government treats as the patta-holder and how the land is classified; it is strong supporting evidence but not a guarantee of clear legal title. Ownership in India is established by tracing a chain of validly executed and registered deeds and testing it against encumbrance and litigation records, which is what a Title Search Report does.

How far back does the online EC in Tamil Nadu go? Computerised registration data on TNREGINET generally reaches back to around the late 1980s. For a full title search you often need an unbroken record of about 30 years, so anything older than the digitised period usually requires a manual encumbrance search at the relevant Sub-Registrar Office (SRO). Always note the exact period your online EC covers.

What is the difference between Nanjai and Punjai land? Nanjai is wetland (irrigated, historically paddy and water-fed cultivation) and Punjai is dryland (rain-fed or unirrigated). The classification, recorded in the Chitta and now carried in the merged Patta, affects valuation, water rights and the approvals you need to develop or convert the land, so it should always be checked before purchase.

Do I still need a lawyer if the Patta and EC look clean? Yes. A clean Patta and a nil EC only confirm what the government records show today, within the years searched; they do not validate the deed chain, capture unregistered claims, or reveal pending litigation. A lawyer reviews the full picture — deeds, classification, encumbrances and litigation — and signs off on title. Platforms like Deedwise automate the gathering and drafting, but the legal opinion remains with the lawyer.
