Mother Deed / Title Deed — The Foundation Document
The title deed (also called the mother deed or parent document) is the most fundamental document in any plot purchase. It establishes the complete ownership history from the original government grant or earliest recorded owner to the current seller.
What to Verify
- Seller's name must exactly match the name in the most recent registered deed
- All previous sale deeds in the chain must be registered — unregistered transfers are legally weak
- Check for any endorsements, corrections, or cancellations on the original
- Obtain documents covering at least the last 30 years of ownership history
If the seller can only produce photocopies and not original registered deeds, do not proceed without independent legal advice.
Encumbrance Certificate (EC) — Your Most Critical Document
The Encumbrance Certificate (EC) is arguably the single most important document when buying a plot in Chennai. Issued by the Sub-Registrar's office, it lists every registered transaction related to the property — sales, mortgages, gifts, partitions, releases — for a specified period.
What to Check in the EC
- Request EC Form 15 (detailed) for at least 13 years — ideally 30 years
- The EC must show the current seller as owner with no outstanding mortgage or lien
- Any bank loan listed must have a corresponding Deed of Release before sale proceeds
- Obtain EC directly from the Sub-Registrar — never accept only a seller-provided copy
- A "nil encumbrance" EC (Form 16) for periods with no transactions is perfectly acceptable
Apply at the nearest Sub-Registrar Office with the survey number and address, or use the Tamil Nadu Registration Department portal at tnreginet.gov.in. Cost: typically ₹100–₹200 per year of search.
Patta and Chitta — Revenue Department Records
Patta and Chitta are revenue records maintained by the Tamil Nadu Revenue Department — entirely separate from registration records. Both are essential for any plot purchase in Chennai.
Patta — Ownership Record
Patta is the official revenue record of who legally owns the land. It includes the owner's name, survey number, land area, and assessment details. Patta must be in the seller's current name. If it's still in a deceased person's name, legal heirs must complete a name transfer before any sale can proceed.
Chitta — Land Classification
Chitta records whether the land is Nanjai (wet land, irrigated) or Punjai (dry land). Always confirm the plot is Punjai classification — Nanjai land has restrictions that complicate residential use and home loan eligibility.
Apply online via tnpatta.net or the Tamil Nadu e-Services portal. You can also obtain them at the taluk office. Always cross-verify the online extract against the physical original provided by the seller.
CMDA / DTCP Layout Approval — Non-Negotiable
Every plot in a legally sub-divided layout must have either CMDA or DTCP layout approval. Without it, the consequences are severe:
- Banks will refuse home loans — no exceptions
- The plot cannot be legally converted for construction
- Future resale becomes extremely difficult
- The layout may face demolition orders under court direction
Always ask for the Layout Approval Order (LAO) number and verify it independently:
- CMDA approvals: cmda.gov.in
- DTCP approvals: Contact the district planning office or Tamil Nadu DTCP portal
Many sellers present panchayat approval as equivalent to CMDA/DTCP layout approval. It is not. Banks will not finance panchayat-only plots and resale is severely restricted.
Building Plan Approval — Required Before You Construct
Many buyers confuse layout approval with building plan approval — they are entirely separate permissions. Layout approval only permits the sub-division of land. To build a house, you need a separate Building Plan Approval (BPO) from CMDA, DTCP, or local municipality.
- Apply with architectural drawings by a licensed structural engineer
- Minimum plot size, road setbacks, and Floor Space Index (FSI) limits apply
- Required before breaking ground — construction without approval risks demolition notices
- Timeline: typically 30–90 days for CMDA/DTCP; faster for municipal areas
Documents 7–11: Supporting Documents You Must Not Skip
Property Tax Receipts
Request property tax receipts for the last 3–5 years. Outstanding property tax becomes a liability of the new owner after registration. Confirm all dues are cleared before finalising the deal and request a no-dues certificate from the local body.
Field Measurement Book (FMB) / Survey Settlement Register
The FMB is the official survey record showing exact measurements, boundaries, and adjacent survey numbers. Compare the FMB with the physical plot during your site visit — any discrepancy in dimensions or boundary lines must be resolved before purchase.
A Register Extract
The A Register is maintained by the Village Administrative Officer (VAO) and records land classification, extent, ownership, and tax assessment. Request the latest extract and confirm it is consistent with Patta records — any discrepancy needs resolution.
NOC from Bank (If Property is Mortgaged)
If the seller has an active home loan or mortgage, they must obtain a No-Objection Certificate from their lender confirming the loan is fully repaid. Without this, the bank's lien transfers to you as the new owner — a serious legal risk.
Link Documents (Chain of Title — 30 Years)
Link documents are the previous sale deeds establishing the ownership chain back to the original grant. Request a minimum of 3 prior deeds or 30 years of history. Any gap in this chain should be investigated by a property advocate before you commit.
