20 Legal Documents Required for Property Purchase | Chennai Property Guide 2026 Chennai Property Guide Ownership Approvals Tax Records Financial FAQ 2026 Checklist 20 Legal Documents Required forProperty Purchase in Chennai From Velachery flats to ECR villas — every document you must verify before paying a single rupee. 📅 Updated May 2026 📖 12 min read 📍 Chennai & Tamil Nadu Buying a home in Chennai seems exciting, but it can become stressful and expensive if proper legal verifications aren’t done. Every year, property buyers in Tamil Nadu face issues like disputed ownership, fake documents, approval problems, and registration delays — often because one or two important documents weren’t reviewed before paying. This guide helps you avoid every one of these costly mistakes. Part 1 Ownership & Title Documents 1 Sale Deed விற்பனை பத்திரம் The sale deed is the primary legal document for property transfer in India. It is executed between buyer and seller at the Sub-Registrar’s office and becomes solid proof of ownership once registered. Tip: For resale properties, always insist on the original document — never accept a photocopy. Verify the property documents, survey number, and measurements match what you were told. 2 Parent Document தாய் பத்திரம் Parent documents establish the historical chain of ownership — every sale deed, gift deed, and partition deed going back 30 years (to the original land grant). A clean title with no gaps means no unknown claimant can appear after purchase. Warning: If documents are missing, an undisclosed transfer exists, or inheritance is unclear — do NOT proceed without a legal advocate’s advice. This is especially critical in Chennai where many properties changed hands during land acquisition or government scheme periods. 3 Encumbrance Certificate (EC) சுமைச் சான்றிதழ் The EC is a record of all registered transactions against a property — mortgages, sale deeds, gift deeds, court orders, and liens — obtained from the Sub-Registrar’s Office. It proves the property is free from legal and financial encumbrances. How to obtain: Get Form 15 (if transactions exist) or Form 16 (nil encumbrance). The EC must cover the full period of the current seller’s ownership — ideally 30 years. 4 Patta & Chitta பட்டா மற்றும் சிட்டா Patta is a government-issued revenue record that identifies the legal possessor of a land parcel, issued by the VAO or Tahsildar. Chitta is an annual register maintained by the VAO showing cultivation and possession details. For apartments, land should have Patta in the builder’s or society’s name. For resale plots and houses, Patta must be in the seller’s name with survey numbers matching the sale deed. 5 Adangal / Field Measurement Book (FMB) The FMB Sketch Book is the official survey map showing the exact dimensions and boundaries of the land parcel, including land ownership, area, land use type, and water source. Always compare the FMB sketch with actual ground measurements. Critical: If the Adangal shows the land as ‘PORAMBOKE’ (government land), tank bed, river bed, or forest land — do NOT purchase it, regardless of how many generations the seller has possessed it. Part 2 Government Approvals & Permissions 6 CMDA / DTCP Building Approval In Chennai, any building construction requires prior approval from CMDA (Chennai Metropolitan Development Authority) for properties within the Chennai Metropolitan Area, or DTCP (Directorate of Town and Country Planning) for properties elsewhere in Tamil Nadu. Without approval, the building is illegal and can be demolished. Warning: Many builders in Chennai suburbs construct additional floors beyond what’s approved. Buying such property makes you legally liable. Always verify the original approval with its plan number and cross-check it with the actual floors and built area. 7 Land / Layout Approval (for Plots) If buying a plot in a layout or gated community, the developer must have obtained layout approval from CMDA or DTCP. Layout approval specifies total extent, number of plots, road widths, open space reservations, and utility reservations. Warning: Buying a plot in an unapproved layout means you cannot legally construct a building, obtain utility connections, or get bank loans. This is one of the most common property fraud scenarios in Chennai. 8 RERA Registration Certificate (Tamil Nadu) Under the Real Estate (Regulation and Development) Act 2016, all residential projects with more than 8 units or over 500 sq.m. of development must be registered under TNRERA (Tamil Nadu Real Estate Regulatory Authority). RERA is the strongest buyer-protective requirement in Indian real estate law. Verify at: rera.tn.gov.in — search by project name or registration number. An unregistered project is a serious violation; report it to RERA and strongly reconsider your purchase. 9 Completion Certificate (CC) The CC is issued by CMDA or the local municipality after verifying the construction was completed in accordance with the approved building plan. It confirms the building is structurally sound and adheres to building regulations. Without a CC, the building is technically incomplete in the eyes of the law — banks may refuse home loans and utility connections can be problematic. 10 Occupancy Certificate (OC) The OC is issued by the local planning authority confirming the building is safe for occupation, following a physical inspection of the completed building. Note: OC and CC are different — CC confirms construction as per plan; OC confirms safe to live in. RERA mandates builders to provide OC before handing over possession. Your right: Insisting on the OC before paying the final installment is legally your right as a buyer. 11 No Objection Certificates (NOCs) Depending on location, type, and environmental factors, various NOCs may be required: Fire NOC from Tamil Nadu Fire and Rescue Services (buildings above 15m), Airport Authority NOC for properties within Chennai Airport’s height restriction zones, Environmental Clearance for large commercial projects, and CRZ Clearance for Coastal Regulation Zone properties near ECR / OMR. Part 3 Tax & Revenue Records 12 Property Tax Assessment / Khata சொத்து வரி ரசீது In Chennai, this is maintained by the Greater Chennai Corporation (GCC) as the local government’s record of the property for taxation.
