Legal Checklist Before Buying Property in India: 2026 Guide

Why sequence matters in a legal due diligence checklist

Most checklists list documents alphabetically or by category, which makes intuitive sense for organisation but obscures dependency: you cannot meaningfully verify a builder’s RERA compliance before confirming the underlying land title is clean, and you cannot finalise a home loan application until the property’s legal status is confirmed. The sequence below follows the order that actually protects a buyer, front-loading the checks that, if they fail, should stop the transaction before any money changes hands.

Phase 1: Ownership and title verification

• Title deed and complete chain of title, traced back a minimum of 15 to 30 years depending on the property’s age and complexity.
• Encumbrance certificate confirming no outstanding mortgages, court attachments, or other registered claims.
• Khata or municipal record confirming current tax assessment matches the seller’s name.
• Mutation record cross-checked against the title chain (noting that mutation alone is not conclusive proof of ownership per Supreme Court rulings).
• For inherited properties: death certificate, succession certificate or probate, family tree affidavit, and relinquishment deeds from all co-heirs not party to the sale.

Phase 2: Construction and regulatory compliance

• RERA registration verified directly on the state portal, not just from builder marketing material.
• Approved building plan, cross-checked against the actual constructed building on a physical site visit.
• Commencement certificate confirming legal start of construction.
• Completion certificate and occupancy certificate, for ready-to-move properties.
• NOCs from fire department, water board, and electricity board.
• For plotted developments: land use or zoning approval, and a Non-Agricultural (NA) conversion order if the land was originally agricultural.

Phase 3: Financial and tax clearance

• Property tax receipts confirming no outstanding municipal dues.
• Loan closure certificate and registered release deed, if the seller previously mortgaged the property.
• Society NOC confirming no outstanding maintenance or other dues, for resale apartments.
• Verification of the seller’s PAN and bank details, relevant for TDS compliance on the transaction (1 percent TDS applies on property transactions above Rs 50 lakh under Section 194-IA).

Phase 4: Agreement and registration documents

• Agreement to Sell reviewed carefully, with all promised terms, possession date, and penalty clauses for delay explicitly documented (verbal promises have no legal value).
• Stamp duty calculated correctly based on the higher of sale price or circle rate, and the payment challan generated.
• Sale Deed drafted, reviewed by a lawyer, and registered at the Sub-Registrar’s office with both parties and witnesses present.
• Possession letter (for new purchases) clearly stating the date and conditions of possession.

Phase 5: Post-registration follow-through

• Mutation application filed at the local revenue or municipal office.
• Society membership and share certificate transfer completed.
• All original documents organised, with certified copies retained separately, for future resale, inheritance planning, or tax filing.

The most commonly skipped checks

Two checks are skipped more often than any others, and both carry outsized risk. First, an independent encumbrance certificate: many buyers accept the seller’s copy rather than applying independently, missing the chance to catch a discrepancy the seller may not even be aware of. Second, a physical site visit cross-checking the approved building plan against the actual constructed structure: unauthorised floors or extensions are far more common than buyers expect, particularly in older or informally developed buildings, and this check requires physical verification, not just document review.
