The Ultimate Due Diligence Checklist Before Buying a Property in India (2025)

Phase 1: The Legal Document Checklist

This is the foundation of your investigation. Ask the seller for a complete file with the following original documents for verification:

• Title Deed / Sale Deed: This document establishes the seller's ownership. Ensure it is registered and stamped.
• Parent Deed (Mother Deed): Trace the ownership history of the property back at least 30 years. Ensure an unbroken and clear chain of transfers. Any missing link is a huge red flag.
• Encumbrance Certificate (EC): Obtain an EC from the sub-registrar's office for the last 30 years. This reveals if there are any existing mortgages, loans, or legal claims against the property.
• Latest Property Tax Receipts: Verify that all property taxes are paid up to date and the receipts are in the seller's name.
• Khata Certificate and Extract: Issued by the local municipal body, this is required for property registration and tax payment. Verify the owner's name.

Phase 2: The Building & Layout Approval Checklist

This is crucial for ensuring the property is legally constructed.

• RERA Registration (for projects post-2016): Verify the project's RERA registration number on the state's official RERA website. Check the project details and completion date.
• Approved Building Plan: Get a copy of the building plan sanctioned by the municipal authorities. Compare it with the actual constructed building to check for any deviations or illegal constructions.
• Commencement Certificate & Occupancy Certificate (OC): A Commencement Certificate allows the builder to start construction. The Occupancy Certificate is issued after completion, certifying that the building is fit for habitation. A property without an OC is technically illegal.
• Land Use Approval: Verify from the city's master plan that the land is zoned for residential purposes.

Phase 3: The Financial and Physical Checklist

Look beyond the papers to the physical and financial reality.

• Physical Inspection: Visit the property multiple times. Check for structural issues like cracks, dampness, and the quality of construction, plumbing, and electricals.
• Society No-Objection Certificate (NOC): For apartments, get an NOC from the society confirming they have no objection to the sale. Also, get a statement of any outstanding maintenance dues.
• Utility Bills: Check for pending electricity, water, and gas bills.
• Independent Valuation: Hire a professional valuer to get an independent assessment of the property's market price. Don't just rely on the seller's asking price.
