Patta, EC & Legal Documents Required to Buy Property in Chennai

Property transactions in Chennai are governed by Tamil Nadu revenue laws, the Registration Act, town & country planning acts, and local municipal regulations. Every buyer must ensure title clarity, lawful land use, and statutory compliance before purchasing.

1. PATTA 

1.1 What Is Patta?
Patta is a government-issued land revenue record maintained by the Revenue Department. It officially records who owns a particular piece of land according to government records.
A patta is not merely an identity document; it is part of the Record of Rights, which determines

• Ownership
• Land classification
• Tax liability
• Legal recognition of possession

1.2 Legal Nature of Patta

• Patta does not create ownership by itself, but
• It is strong supporting evidence of ownership when read along with the Sale Deed
• Courts rely heavily on Patta during land disputes

1.3 Details Mentioned in a Patta
A Patta contains:

• Patta Number (unique ID)
• Name(s) of owner(s)
• Survey Number & Sub-division Number
• Total land extent (sq.m / acres)
• Village, Taluk, District
• Land classification:

1. Wet land (Nanjai)
2. Dry land (Punjai)
3. Residential land

Tax assessment details
All these details must exactly match the Sale Deed and EC.

1.4 Why Patta Is Critical in Chennai

1. Government land (Poramboke)
2. Encroached land
3. Multiple ownership claims

1.6 Patta Transfer

• After registration:

1. Legal disputes
2. Problems during resale
3. Loan rejection

2. ENCUMBRANCE CERTIFICATE (EC)

• Subject to registered claims

2.2 What EC Covers
EC includes only registered documents, such as:

• Sale deeds

2.4 Importance of EC

• Confirms clear and marketable title
• Detects existing loans or charges
