Checking Property in Tamil Nadu: Patta, EC and Approvals Explained

Tamil Nadu has its own way of verifying property. A flat in Chennai, land in Coimbatore or a villa in Madurai all call for TNREGINET for land records, the Patta Chitta system for proof of ownership, CMDA and DTCP for development approvals and the Registration Department for encumbrance certificates.

Below, each step of the process is explained, with the points peculiar to the state, the pitfalls that recur, and the way technology is changing title search in Tamil Nadu.

Laws that govern property in Tamil Nadu

Agricultural holdings in Tamil Nadu fall under the Tamil Nadu Land Reforms Act, 1961, while the Transfer of Property Act, 1882 applies to every property transaction. TNREGINET holds digital records for most properties, so the state is among the more advanced for online verification.

The main legal frameworks:

• The Registration Department of Tamil Nadu, which registers properties, issues encumbrance certificates and verifies documents
• The Patta and Chitta system: the Patta records who owns the land and the Chitta or Adangal records how it is measured
• The Tamil Nadu Town and Country Planning Act, 1971, under which DTCP governs urban planning and approvals
• The CMDA Act, 1972, which gives the Chennai Metropolitan Development Authority control of planning in the Chennai Metropolitan Area
• The Coastal Regulation Zone (CRZ) Notification, 2019, which is critical for coastal property near Chennai

Tamil Nadu is unusual in having two urban planning authorities. CMDA looks after the Chennai Metropolitan Area (Chennai, plus parts of the Tiruvallur, Kanchipuram and Chengalpattu districts) while DTCP (Directorate of Town and Country Planning) covers the rest. Which of them governs your property matters, not least for the due diligence that banks require for home loans.

Government portals for verifying property in Tamil Nadu

Portal 1: TNREGINET (https://tnreginet.gov.in)

TNREGINET is the state's comprehensive land records portal. It gives you:

• Patta — the revenue record of ownership
• Chitta or Adangal — the survey record with land measurements
• FMB (Field Measurement Book) sketches — plot boundaries and survey numbers
• A-Register — property details village by village
• Encumbrance Certificates — the history of transactions

Most districts let you order certified documents online. Procedures and registration fees are the same across the state, although some rural areas still need physical verification.

Portal 2: The Tamil Nadu Registration Department (https://www.tnreginet.gov.in/portal)

This portal handles:

• Applications for Encumbrance Certificates (EC), which usually arrive in 3-7 days
• Certified copies of property documents from sub-registrar offices
• Search by document number in any of 275+ sub-registrar offices
• Online payment for registration services

EC fees are uniform in Tamil Nadu at ₹50 for a search up to 30 years. See our complete encumbrance certificate guide for India.

Portal 3: CMDA (https://www.cmdachennai.gov.in)

For property in the Chennai Metropolitan Area, CMDA provides:

• Approvals of planning permission for new construction
• Verification of the status of building plan approval
• Master Plan maps that show land use zones (residential, commercial, industrial, CRZ and others)
• Issue of the Occupancy Certificate

CMDA's jurisdiction covers about 1,189 sq km across four districts. Layouts inside CMDA limits that lack approval face strict enforcement.

Portal 4: DTCP (https://www.townplanning.tn.gov.in)

For property outside the Chennai Metropolitan Area:

• Approvals of layouts for plotted developments
• Permissions for building plans in municipal areas
• Verification of the land use zone
• Identification of layouts that are unauthorised

DTCP functions through regional offices at Coimbatore, Madurai, Tiruchirappalli and other major cities.

Portal 5: Patta Chitta (https://eservices.tn.gov.in/eservicesnew/Land)

This portal, linked to TNREGINET, offers:

• Online viewing of Patta and Chitta by district, taluk, village and survey number
• Download of the Adangal (the field register with cultivation details)
• FMB sketches downloadable as PDF
• Look for encroachments and revenue recovery notices

Tamil Nadu was among the first states to digitise Patta records fully. A Patta, though, does not prove ownership. It confirms only the revenue records, so always cross-verify with registration documents.

A step-by-step process for Tamil Nadu

Step 1: Pin down the property

Collect the basic facts:

• Survey number (mandatory for rural and peri-urban land)
• Plot or door number (for urban properties)
• District, taluk and village (the administrative boundaries)
• The jurisdiction of the sub-registrar office (for the EC search)
• CMDA or DTCP jurisdiction (which decides who approves)

For a property on the Chennai coast, verify the CRZ classification (CRZ-I, II, III or IV), because construction norms differ greatly between them.

Step 2: Verify ownership with Patta and Chitta

Go to TNREGINET and retrieve:

• Current Patta — shows who holds revenue rights
• Chitta or Adangal — gives the survey number, extent and classification (dry, wet or poramboke)
• FMB Sketch — marks the boundaries and adjoining survey numbers

Warning signs:

• The Patta holder's name differs from the seller's
• The survey number is marked "poramboke" (government land not meant for private sale)
• The land is classified as "forest land" or "assigned land" (restrictions on alienation apply)
• Recent transfers of Patta with no matching registered documents

Step 3: Get an Encumbrance Certificate for 13-30 years

File the EC application on the TNREGINET portal or visit the concerned sub-registrar office. In Tamil Nadu you can usually choose between:

• A 13-year EC — the minimum for home loans under RBI norms
• A 30-year EC — advised for old properties and inherited land

An EC reveals every registered transaction, whether sale deed, gift deed, mortgage, will, partition deed or lien. How deep Tamil Nadu lawyers go in a title search depends on the choice of 13-year or 30-year chain.

What to look for:

• An ownership chain from the present seller back through every earlier owner, with no break
• No mortgages or charges outstanding
• No adverse entries such as court orders, seizures or auction notices
• Names spelled the same way across documents (Tamil Nadu documents often vary)

Step 4: Verify the sale deed and the parent documents

Get certified copies of:

• The current sale deed from the sub-registrar office
• Every parent document named in the EC chain
• Gift deeds or wills, if the property was inherited
• Partition deeds, if it comes from joint family property

Check for:

• Correct payment of stamp duty (7% for a sale and 4% for a gift in Tamil Nadu)
• Registration at the sub-registrar office with proper jurisdiction
• Proper execution (signatures, witnesses, identification)
• No mismatch in survey numbers, extents or boundaries

Where a property was transacted through a power of attorney (GPA against SPA), confirm that the PoA was registered and that its holder had explicit authority to sell.

Step 5: Look for litigation in Tamil Nadu courts

Search for pending cases in:

• District Courts, through the eCourts portal
• The High Court of Madras, through the Madras HC portal
• City Civil Courts (Chennai has its own jurisdiction)
• Revenue Courts, for land disputes

Court records in Tamil Nadu are well digitised, yet older cases may not show online. For a thorough check on pending court cases on a property, a visit to court offices may be needed if the property has a disputed history.

Step 6: Verify CMDA and DTCP approvals

In CMDA areas (Chennai Metro):

• Confirm the layout has CMDA approval, which is mandatory for plotted developments since 1972
• Verify the Building Plan approval for built properties
• Confirm that an Occupancy Certificate was issued
• Check the zoning in the master plan (stay away from properties in CRZ-I or CRZ-III areas where construction is banned)

In DTCP areas (the rest of Tamil Nadu):

• Verify the layout approval at the DTCP regional office
• Check the building plan approval from the local municipality or panchayat
• Confirm compliance with the Development Control Rules

A frequent violation: Many old properties in Chennai predate CMDA's jurisdiction. For these, find out if the construction qualifies for regularisation under present norms. See also how OC and CC differ.

Step 7: Check property tax and dues

Check for:

• Property tax dues at Chennai Corporation, the municipality or the panchayat
• Charges for water and sewage (Chennai Metro Water, local bodies)
• Dues for electricity (TANGEDCO)

Property tax can be paid online in Tamil Nadu through the municipal portals. Clear any arrears before buying so that attachment proceedings do not follow.

Step 8: Inspect the site

Hire a surveyor to:

• Match physical boundaries with the FMB sketch
• Check for encroachments by neighbours
• Verify access to the property (a right of way of 6 feet at minimum is needed for building approval)
• Identify unauthorised constructions
• Confirm the property is not waterlogged or prone to floods (critical in Chennai in the monsoon)

For coastal properties, confirm that the construction follows the CRZ setback norms.

Documents and fees in Tamil Nadu

The essential documents

• An Encumbrance Certificate costs ₹50 for a 30-year search
• Patta and Chitta cost ₹15-20 online
• An FMB Sketch costs ₹20-30, based on how complex the survey is
• A certified copy of the sale deed is ₹50-100 per document
• The CMDA or DTCP layout approval, in copy, costs ₹500-1,000
• Building Plan Approval and OC together come to ₹1,000-2,000
• Property Tax Receipt (for the latest year)
• Land Conversion Certificate (if agricultural land was converted to non-agricultural) — see the land conversion guide

Stamp duty and fees on registration

Tamil Nadu charges:

• Stamp duty: 7% of value on sale deeds; a woman buying in her own name pays 4% on property valued up to ₹50 lakh
• Registration fee: 1% of the value, capped at ₹1 lakh once the property is worth over ₹1 crore
• Local body tax: 1% in Chennai Corporation and other municipalities

Example, for a property worth ₹1 crore:

• Stamp duty: ₹7,00,000, falling to ₹4,00,000 for a woman buyer
• Registration: ₹1,00,000 (capped)
• Local body tax: ₹1,00,000
• Total: ₹9,00,000 (or ₹6,00,000 for a woman)

How long each step takes

• EC issue: 3-7 days (online)
• Patta and Chitta: viewing is instant online, and certified copies take 2-3 days
• Copies of documents from the sub-registrar: 5-10 days
• Verifying CMDA or DTCP approval: 7-15 days (if you apply for fresh information)
• Whole due diligence: 15-30 days, depending on how complex the property is

Problems peculiar to Tamil Nadu

1. Delays in transferring the Patta

Issue: Even after registration, revenue authorities may take months or years to transfer the Patta (mutation).

Effect: The new buyer's name does not show on the Patta, which causes trouble with property tax, electricity connections and later sales.

Solution: File a Form 1 application at the Taluk Office within 30 days of registration, and follow up regularly. Some districts let you track it online. Our property mutation guide has the detailed steps.

2. Layouts without approval

Issue: Many layouts in the suburbs of Chennai (Tambaram, Ambattur, Avadi) and in Coimbatore have no CMDA or DTCP approval.

Effect: Banks refuse loans, municipalities reject applications for building plans, and demolition is a risk if the government enforces the rules.

Solution: Verify layout approval thoroughly. If a layout is unapproved, negotiate a significant discount and accept that loans and approvals may be hard to get. Some layouts may qualify for regularisation under Tamil Nadu's periodic regularisation schemes.

3. Confusion between CMDA and DTCP

Issue: Properties on the boundary of the Chennai Metropolitan Area often have unclear jurisdiction, as some areas moved from DTCP to CMDA in phases.

Effect: An approval from the wrong authority makes the construction illegal.

Solution: Confirm jurisdiction from the latest CMDA Master Plan, and in boundary cases speak to both authorities. A property that DTCP approved before CMDA expanded may need conversion approval.

4. CRZ violations on the Chennai coast

Issue: Many properties in Besant Nagar, Thiruvanmiyur, Neelankarai and along ECR were built in breach of CRZ setback norms (which now require a setback of 50-200m from the High Tide Line, depending on the zone).

Effect: Such properties are at risk of demolition, cannot get building plan approvals for renovation and have a restricted resale value.

Solution: Confirm a coastal property's CRZ class with the Tamil Nadu State Coastal Zone Management Authority. Steer clear of CRZ-I and heavily restricted CRZ-III properties, and take expert legal advice on whether regularisation is possible.

5. Sales of poramboke land

Issue: Government poramboke lands (village commons, water bodies, roads and burial grounds) are sometimes sold on fake or forged documents.

Effect: The money is lost entirely, and the buyer faces criminal liability if fraud is established.

Solution: Always check that the Patta shows private "Patta land" and not poramboke. Cross-check the colours on the FMB sketch (red marks poramboke in most Tamil Nadu surveys). See the checks on the prohibited property list.

6. Disputes over Joint Development Agreements

Issue: A large number of Chennai properties are held under JDAs (Joint Development Agreements) with builders, and landowners often keep executing sale deeds after signing the JDA.

Effect: Several sale deeds on the same property and long litigation.

Solution: Go through the EC for any registered JDA. If one exists, confirm that the builder consented to the sale. Avoid properties with unresolved JDA disputes.

7. Partition problems in ancestral property

Issue: Hindu ancestral properties under the Hindu Succession Act may have several legal heirs with rights, even if the Patta shows only one name.

Effect: Claims by other heirs in future and a clouded title.

Solution: For ancestral property, obtain a family settlement deed or a release deed from every legal heir. Verify through the family tree and succession certificates.
