Buying an apartment or villa in Chennai is a major financial and emotional decision. However, many buyers focus only on price and location while overlooking critical legal requirements, which can later lead to disputes, financial losses, or even cancellation of ownership. This comprehensive guide explains all the legal rules, approvals, documents, and precautions you must know before purchasing a flat or villa in Chennai, Tamil Nadu.
1. Governing Laws for Property Purchase in Chennai
Property purchases in Chennai are governed by multiple central and state laws:
Key Laws Applicable
- Real Estate (Regulation and Development) Act, 2016 (RERA)
- Tamil Nadu Town and Country Planning Act
- Registration Act, 1908
- Indian Stamp Act (Tamil Nadu Amendment)
- Transfer of Property Act, 1882
- Tamil Nadu Apartment Ownership Act
Understanding how these laws work together ensures a legally safe purchase.
2. RERA Registration – Mandatory for Most Projects
What is RERA?
RERA protects homebuyers by ensuring transparency and accountability from builders.
Legal Rule
- All apartment projects above 500 sq. meters or more than 8 units must be RERA registered
- Villas forming part of a gated project also fall under RERA
What Buyers Should Check
- RERA registration number
- Approved layout and building plan
- Project completion date
- Builder’s legal title to the land
Verify on the Tamil Nadu RERA website before paying any advance.
3. Land Title Verification – The Most Important Legal Check
Clear and Marketable Title
The seller (builder or individual owner) must have:
- Absolute ownership
- No disputes or claims
- No legal encumbrances
Documents to Verify
- Sale Deed (minimum 30 years chain)
- Encumbrance Certificate (EC)
- Patta / Chitta / Adangal
- Parent documents
Never rely only on photocopies—always verify originals.
4. CMDA / DTCP Approval – Planning Authority Clearance
Why This Matters
Without proper approval, the building can be:
- Declared illegal
- Denied water, sewage, or electricity connections
- Demolished in extreme cases
Approval Authorities
Ensure:
- Layout approval
- Building plan approval
- Floor Space Index (FSI) compliance
5. Building Approval and Completion Certificate
Mandatory Legal Requirements
- Building Plan Approval
- Completion Certificate (CC)
- Occupancy Certificate (OC)
Why OC is Critical
- Required for legal occupation
- Mandatory for home loans
- Needed for resale and utilities
Buying a flat without OC is legally risky.
6. Sale Agreement and Sale Deed
Sale Agreement
- Legally binding contract
- Specifies price, possession date, penalties
- Must be registered if possession is delayed
Sale Deed
- Final ownership document
- Must be registered at Sub-Registrar Office
- Only after registration does ownership legally transfer
Always review both documents through a property lawyer.
7. Stamp Duty and Registration Charges in Tamil Nadu
Current Charges (Subject to Change)
- Stamp Duty: 7%
- Registration Fee: 4%
- Total: 11% of property value
Stamp duty is calculated on:
- Guideline value or
- Actual sale value (whichever is higher)
8. Home Loan and Bank Legal Verification
Banks conduct:
- Title verification
- Approval validation
- Encumbrance check
However, bank approval does not replace your own legal due diligence.

If buying from a builder under JDA:
- Ensure landowner consent
- Verify Power of Attorney
- Confirm revenue sharing terms
JDAs carry higher legal risk if documents are unclear.

Legal Requirements After Purchase
- Property tax transfer to buyer’s name

- Formation of Apartment Owners Association
- Registration under Tamil Nadu Apartment Ownership Act
