Property Due Diligence Before Buying Real Estate in Chennai
What is property due diligence and why does it matter?
Property due diligence is the legal and factual investigation of a property before you buy it, carried out to confirm that the seller has a clear and marketable title and that the property is free of legal defects. It matters because a sale deed transfers only the rights the seller actually holds — if the title is defective, the registration of your purchase will not cure that defect, and you may inherit litigation, encumbrances or claims by third parties.
In Chennai, property disputes frequently arise from incomplete title verification, undisclosed mortgages, or construction that lacks proper planning approval. Diligence carried out before payment is far less expensive than litigation afterwards.
Which documents should you examine?
The core documents to review are the chain of title and the records that reveal claims against the property:
- Parent documents / chain of title: the prior sale, gift, settlement or partition deeds tracing ownership, generally for the preceding 30 years.
- Mother deed and the latest title deed in the seller's name.
- Encumbrance Certificate (EC): obtained from the Sub-Registrar, showing registered transactions and charges over a chosen period.
- Patta and revenue records / chitta and adangal: to confirm the revenue entries and classification of the land.
- Approved building plan and planning permission from CMDA or the local body, and the completion certificate where relevant.
- Tax receipts (property tax, water and electricity) showing the property is free of dues.
How do you verify the title and seller's authority?
Verify both the documents and the person executing the sale. Confirm the seller's identity and capacity, and where a sale is executed through an agent, examine the power of attorney carefully to confirm it is valid, registered where required, and not revoked.
Key checks include:
- Confirming the title is clear, marketable and free from competing claims;
- Checking the EC for mortgages, attachments or court orders;
- Confirming that, for agricultural or specially classified land, any conversion or permission required has been obtained;
- For apartments, reviewing the developer's title, the approved plan, the undivided share of land, and the status of the project.
What about RERA, encumbrances and approvals for new projects?
For an under-construction apartment or plotted development, check that the project is registered with the Tamil Nadu Real Estate Regulatory Authority (TNRERA) under the Real Estate (Regulation and Development) Act 2016, and review the registration details, approved plans and the promoter's disclosures. A registered project gives you statutory rights and access to a defined complaint mechanism.
How is the purchase completed and registered?
Once diligence is satisfactory, the sale deed is drafted, stamp duty and registration fees are paid, and the deed is registered before the jurisdictional Sub-Registrar under the Registration Act 1908. Registration of a sale deed for immovable property of value above the statutory threshold is compulsory; an unregistered deed does not pass title. After registration, mutation of revenue records in the buyer's name should be applied for.
