GROWTH A sale deed proves a transaction happened. It doesn't, by itself, prove the seller had clear title to sell, or that the plot is free of disputes and encumbrances. Buyers who stop at the sale deed are checking the last document in the chain, not the ones that actually establish whether the land was clean to sell in the first place.
1. The Encumbrance Certificate (EC). This is the single most important document after the sale deed itself. An EC, obtainable from the Sub-Registrar's office, shows every registered transaction against a specific piece of land over a chosen period — sales, mortgages, gifts, leases. A clean EC for a reasonable look-back period (buyers typically ask for 13 to 30 years) is what tells you the land hasn't been mortgaged or sold to someone else along the way.
2. Patta and Chitta (or the equivalent land records). These are the revenue department's own records of who holds the land and how it's classified — patta identifies the registered owner, chitta confirms the land classification (an important check for whether the plot is legally treated as land suitable for residential layout, not agricultural land pending conversion). For a DTCP-approved layout, these should already be in order, but a buyer or their advocate should still ask to see them rather than assume.
3. The DTCP approval letter and the approved layout plan. A developer stating a layout is "DTCP approved" is a claim; the actual approval letter with its reference number, matched against the approved layout plan showing your specific plot's number, size and boundaries, is the proof. Growth Town's DTCP Approval No. 140/2025 and RERA Registration No. TNRERA/35/LO/3821/2025 are both available on request — any developer should be equally willing to produce theirs.
None of these checks are unique to any one project. They're the baseline due diligence that applies to any plot purchase on the GST Road corridor or anywhere else in Tamil Nadu, and a few days spent verifying them is inexpensive compared to the cost of discovering a title problem after you've paid.
