These digital platforms provide access to important information such as ownership records, Encumbrance Certificates, survey details, land classification, layout approvals, and historical archives. Checking these websites before visiting government offices can help buyers understand the property’s legal status and prepare the correct information for further verification.

Below is a guide to the main official Tamil Nadu government websites where different property records can be found.

TNREGINET Portal – Registration Records and Encumbrance Certificates

https://digitamilnaduarchives.tn.gov.in

These archives store historical records such as:

• Old Settlement Registers (OSR)

Why Checking Government Portals Matters

Using official government portals before visiting offices helps buyers:

• Trace historical land records

These online checks provide a preliminary understanding of the property’s legal status, making offline verification at government offices easier and more efficient.

Conclusion

Tamil Nadu has gradually digitized many land records through official government portals. These websites provide access to important property information such as registration records, revenue records, survey maps, planning approvals, and historical archives.

However, while these portals provide useful insights, buyers should still perform complete verification through the relevant government offices to confirm the authenticity of documents and ensure the property is legally safe for purchase.

Combining online research with on-ground verification remains the most reliable approach for making informed real estate decisions.

Each government office maintains a specific set of property records. Knowing where to verify what helps buyers confirm ownership, boundaries, approvals, and legal status before purchasing land.

Below is a clear guide explaining which office verifies each type of property record in Tamil Nadu.

If You Want to Verify Ownership

Ownership of a property is verified through the Sub-Registrar Office (SRO) under the Registration Department.

The Sub-Registrar office maintains records of all registered property transactions, including:

• Sale deeds
• Settlement deeds
• Gift deeds
• Mortgage registrations

Buyers can request a certified copy of the registered sale deed to confirm that the seller legally owns the property.

It is also recommended to verify the parent document chain for at least 30 years to ensure the property title has no gaps.

If You Want to Verify Encumbrance or Transaction History

The Encumbrance Certificate (EC) is also issued through the Sub-Registrar Office.

The EC shows:

• Previous sale transactions
• Mortgage records
• Legal attachments
• Financial liabilities linked to the property

Checking the EC helps buyers confirm that the land is free from loans or legal disputes.

Property lawyers usually recommend checking the Encumbrance Certificate for at least 30 years.

If You Want to Verify Patta and Land Classification

The Taluk Office under the Revenue Department maintains official land ownership records.

Here buyers can verify:

• Patta
• Chitta
• A-Register

These records confirm:

• The registered owner of the land
• Survey number and extent
• Land classification

Land classification is important because some lands are not legally suitable for residential construction.

Examples include:

• Government land
• Water body land
• Agricultural land that has not been converted

If You Want to Verify Survey Numbers and Property Boundaries

The Survey Department maintains official land measurement records.

The key record used for boundary verification is the Field Measurement Book (FMB).

The FMB sketch shows:

• Exact land boundaries
• Length and width measurements
• Neighboring survey numbers
• Road access details

If there is any doubt regarding land extent or encroachment, buyers can request an official land survey measurement.

If You Want to Verify Local Land Status or Disputes

The Village Administrative Officer (VAO) plays an important role in verifying local land details.

The VAO can confirm:

• Actual possession of land
• Local boundary disputes
• Government land classification
• Encroachments
• Water body restrictions

This local verification step is often useful in suburban or rural areas where unofficial layouts may exist.

If You Want to Verify Layout Approval

Layout approval must be verified with planning authorities.

In Tamil Nadu, the key authorities include:

• CMDA (Chennai Metropolitan Development Authority) – for properties within the Chennai metropolitan area
• DTCP (Directorate of Town and Country Planning) – for areas outside CMDA jurisdiction

These authorities approve:

• Residential layouts
• Road access planning
• Infrastructure provisions
• Open Space Reservation (OSR) areas

Buying land in unapproved layouts can result in legal complications and restrictions on construction.

Common Red Flags Buyers Should Watch For

While verifying property records, buyers should be cautious if they notice:

• Missing parent documents
• Patta not matching the seller’s name
• Survey number mismatches
• Government land classification
• Unapproved layouts
• Encumbrance entries showing loans or disputes

Identifying these issues early can prevent serious financial and legal risks.

Final Thoughts

Before purchasing land, buyers should try to identify and visit the relevant government offices in their locality to verify property records directly. These offices maintain the official records needed to confirm ownership, boundaries, approvals, and legal status of the land. Reaching out to the correct department can help you obtain accurate information and avoid potential legal issues.

In most areas of Tamil Nadu, the offices responsible for property verification are typically located in the following places:

• Sub-Registrar Office (SRO) – Usually located in the main town area, often near courts or administrative zones.
• Taluk Office (Revenue Department) – Typically situated in the Taluk headquarters or main government administrative complex.
• Survey Department / Taluk Survey Office – Often located inside the Taluk Office campus or in a nearby government building.
• Village Administrative Officer (VAO) Office – Usually located within the respective village or local administrative area.
• Planning Authorities (CMDA / DTCP Offices) – Generally found in regional planning offices in major towns or district headquarters.

The locations above are common but may vary by district. Buyers should confirm the exact office locations through Google Maps, local inquiries, or official sources, or consider using Verified.RealEstate (VRE), whose team can handle the verification process directly.

In Tamil Nadu, land is often identified by survey numbers, but actual boundaries on the ground are confirmed only through the FMB Sketch — a vital yet often overlooked land record. FMB stands for Field Measurement Book, and it contains detailed survey drawings that determine the precise shape, measurements, and boundary lines of land parcels.

Whether you’re buying a small plot or verifying inherited property, the FMB sketch is critical for preventing boundary disputes and encroachments.

2. What is an FMB Sketch?

An FMB Sketch is an official, scaled field drawing prepared by the Tamil Nadu Survey Department based on physical ground measurements. It records each survey number’s:

• Shape and dimensions
• Adjacent survey numbers
• Subdivision layout
• Orientation and angles
• Pathways, roads, water bodies, or government lands nearby

FMB sketches are prepared by licensed surveyors using chain and compass or GPS instruments, and they serve as the legal boundary reference in land disputes.

3. Why is the FMB Sketch Important?

FMB sketches are used for:

• Demarcation of land boundaries before registration
• Resolving boundary disputes between neighbours
• Verifying layout approval claims
• Detecting overlaps into OSR land, water bodies, or poramboke areas
• Supporting DTCP/CMDA building permissions
• Establishing undivided share (UDS) in apartments

4. Key Elements in an FMB Sketch

Here’s what you’ll typically find in a Tamil Nadu FMB sketch:

5. FMB vs Layout Sketch vs Village Map

Many buyers confuse the FMB Sketch with layout plans or revenue maps. Here’s the difference:

If accuracy is your goal — to know how much land physically exists and where the borders fall — the FMB sketch is the gold standard.

6. How to Access an FMB Sketch in Tamil Nadu
