Complete Property Due Diligence Checklist for Buying Land or Plots in Tamil Nadu
A step-by-step property due diligence checklist for buying land in Tamil Nadu — covering legal documents, approvals, and verifications you cannot afford to miss.

Complete Property Due Diligence Checklist for Buying Land or Plots in Tamil Nadu
Buying a plot of land in Tamil Nadu is one of the biggest financial decisions most families ever make. The paperwork involved is complex. The terminology is unfamiliar. And the risks — title defects, fraudulent documents, unapproved layouts — are real.
This checklist is not meant to scare you. It's meant to make sure you don't skip something that matters.
Go through every step before you sign the sale deed. Before you pay the advance. Before you assume the deal is clean.
Step 1: Confirm the Seller's Identity and Ownership
Start with the most basic question: does the person selling this property actually have the right to sell it?
Ask for:
Government-issued ID proof of the seller
Original sale deed by which they acquired the property
Legal heir certificate (if the property was inherited)
Power of Attorney documentation (if selling through an agent)
Death certificate of the previous owner (in inheritance cases)
If the seller is a company or trust, ask for board resolutions authorising the sale.
Step 2: Obtain and Review the Encumbrance Certificate (EC)
The EC is non-negotiable. Get it for at least 30 years. Verify it yourself from TNREGINET (tnreginet.gov.in), not from a copy handed to you by the seller.
Check for:
All registered transactions in the period
Any mortgages or charges that remain outstanding
Court attachments or injunctions
Whether the current seller's name appears as the last registered owner
If the seller's name does not appear in the EC as the last owner, something is missing from the chain.
Step 3: Verify the Patta (Revenue Ownership Record)
Download the Patta extract from eservices.tn.gov.in. Check:
Seller's name as the Pattadar
Survey number and subdivision match the sale deed
Land extent matches the sale deed
Land classification (make sure it's not government land or water body)
Whether Patta was recently transferred (and if so, why)
Step 4: Check the FMB Sketch (Field Measurement Book)
The FMB sketch shows the exact shape, dimensions, and boundaries of the land. This is important because:
The physical land you're shown and the land on the sketch should match
Road access must be confirmed
Adjacent survey numbers help you verify the location
Get this from the Survey Department or through eservices.tn.gov.in.
Step 5: Verify the A-Register Extract
The A-Register gives additional revenue department details about the land, including its classification and any government notations. It will tell you if any portion of the land is classified as government land or Poramboke, even if the Patta doesn't clearly show this.
Step 6: Check for Court Cases and Litigation
This step is often skipped — and it can be catastrophic to skip.
Search for any active cases related to the property or the survey number. This includes:
Civil disputes over ownership
Family partition cases
Loan recovery proceedings
Encroachment notices
Court-ordered attachment orders
LandCheck's In-Depth Report includes a dedicated court case and litigation check, because this step requires direct search of court records — it doesn't appear on any government property portal automatically.
Step 7: Run a CERSAI Mortgage Search
As discussed, equitable mortgages don't appear in the EC. Run a CERSAI search to check if any financial institution has a live charge on the property.
If a charge is active, the seller must clear it and obtain a release before the sale proceeds.
Step 8: Verify Layout Approval (DTCP or CMDA)
For plotted developments and residential layouts:
If the property is in Chennai metropolitan area: verify CMDA approval
If the property is outside Chennai: verify DTCP approval
Unapproved layouts are a major risk. Bank loans are harder to get, and the local authority can demolish structures in unapproved areas.
Check approvals on tcp.tn.gov.in (DTCP) or cmdachennai.gov.in (CMDA).
Step 9: Verify RERA Registration (for Builder Projects)
If you're buying from a builder or developer, check whether the project is registered on the Tamil Nadu RERA portal (tnrera.in). RERA registration gives you important legal protections as a buyer.
Step 10: Check for Tax Arrears
Confirm whether property tax is up to date with the local municipal body or panchayat. Outstanding tax dues become the buyer's responsibility after registration.
Step 11: Review the Draft Sale Agreement
Before signing, have a lawyer review:
The schedule of the property (survey number, extent, boundaries)
Payment terms and timelines
Possession conditions
Penalty clauses for default
Step 12: Register the Sale Deed Promptly
After the agreement, do not delay registration. A registered sale deed is the only legally conclusive proof of ownership. Advances paid without registration give you very limited legal protection.
Pay the correct guideline value-based stamp duty and registration fee. Don't undervalue the property to save on stamp duty — it can cause complications during resale.
Step 13: Apply for Patta Transfer After Registration
After registration, apply for mutation (Patta transfer) at the Taluk Office. The Patta should be updated to your name in the revenue records. Without this, you may face complications with utility connections, agriculture, and future sales.
Using LandCheck to Simplify Due Diligence
Going through this list on your own is possible, but time-consuming and technically demanding. LandCheck consolidates most of these checks into a single report — covering EC analysis, Patta verification, FMB, CERSAI, litigation search, and approval status.
You still need a lawyer for the final agreement and registration. But the intelligence you get from a LandCheck report means you go into that process already knowing where the risks are.
