Buying property is the biggest purchase most people ever make — and the one where they do the least legal homework. A beautiful flat with a clean-looking sale agreement can still carry a defective title, an unpaid loan, an inheritance dispute, or an unapproved construction that no amount of paperwork fixes after you've paid. Title due diligence is the unglamorous process of verifying, before you part with money, that the seller actually owns what they're selling and can legally transfer it free of trouble.
Here's exactly what to check, document by document, and the red flags that should make you walk away.
Quick answer: Before buying property, verify the title deed and the chain of ownership (the "mother deed") going back ideally 30 years, obtain an Encumbrance Certificate to confirm there are no loans or charges, check the mutation records and property tax receipts, confirm the approved building plan and land-use/conversion, and check RERA registration for under-construction projects. Get an advocate to issue a title search report, and never rely on a general power of attorney as proof of ownership.
Why title due diligence matters
In India, the government does not guarantee land titles — registration records a transaction, but it doesn't certify that the seller's ownership is flawless. That means the burden of verifying title falls on you, the buyer. A defective title can surface years later as a rival claimant, a bank enforcing an old mortgage, or an heir contesting a sale. Once you've paid, unwinding it is slow, expensive litigation. Due diligence is how you catch the problem while you can still walk away.
The documents you must verify
Ask for and examine:
- The title deed — the current owner's registered document proving how they acquired the property (sale deed, gift deed, partition deed, etc.).
- The chain of title / "mother deed" — the sequence of past transfers, ideally traced back 30 years, to confirm an unbroken, clean ownership trail.
- Mutation records (khata/patta) — the revenue/municipal record showing the property is mutated in the seller's name, which matters for taxes and future transfer.
- Property tax receipts — paid up to date, confirming the seller's possession and that there are no dues.
- Latest utility bills — another possession and dues check.
- For inherited property — the will, succession certificate, or legal-heir documents, and NOCs from other heirs.
- Identity and capacity of the seller — that they're the actual owner and competent to sell (and, for a company or trust, properly authorised).
The Encumbrance Certificate
An Encumbrance Certificate (EC), obtained from the sub-registrar's office (often online), lists the registered transactions on a property over a period — sales, mortgages, charges. A clean EC tells you the property isn't mortgaged to a bank or otherwise charged. If there's an existing home loan, you need the lender's confirmation that it will be cleared and the charge released on sale. Pull the EC for a long enough period to cover the chain you're verifying.
Approvals, land use and RERA
A clean title isn't enough if the construction itself is illegal:
- Approved building plan / sanction from the local authority — confirm the structure matches what was approved (extra floors or coverage can be unauthorised).
- Land use and conversion — agricultural land needs conversion to non-agricultural use before residential/commercial use; verify it.
- Occupancy/completion certificate for completed buildings.
- RERA registration — for any under-construction project, check the project and promoter on your state's RERA portal for registration, approvals, and complaint history.
- Society/builder NOC where applicable, and clearance of maintenance dues.
Get a legal title search report
Don't do this alone. Engage a property advocate to conduct a title search at the sub-registrar's office and issue a title search report / title opinion — a written legal assessment of whether the title is clear and marketable. Banks insist on this before sanctioning a loan precisely because it's the authoritative check. Paying for a proper title opinion is the cheapest insurance against buying a lawsuit.
Red flags to walk away from
- A "GPA sale" offered as proof of ownership — a general power of attorney does not convey title.
- A break or gap in the chain of title that the seller can't explain.
- An EC showing an unreleased mortgage with no clear payoff plan.
- Mismatch between the approved plan and the actual construction.
- Pending litigation, disputed boundaries, or reluctant co-owners/heirs.
- Pressure to pay in cash or close quickly "to avoid paperwork."
Worked example
A buyer likes a resale flat. His advocate traces the chain of title back three decades through successive registered sale deeds — clean. The EC shows one mortgage, which the seller's bank confirms will be released on receipt of the sale proceeds. Property tax is paid up to date, the khata is in the seller's name, and the approved plan matches the building, which has an occupancy certificate. The advocate issues a clear title opinion. Only then does the buyer pay the advance and proceed to a registered sale deed. The one mortgage that could have trapped him was caught — and handled — before any money moved.
Common mistakes
- Skipping the chain of title. A current deed alone doesn't prove a clean history.
- Not pulling an EC. Hidden mortgages surface after you've paid.
- Ignoring plan approvals. Unauthorised construction can be demolished or penalised.
- Trusting a GPA as title. It conveys no ownership.
- Closing without a lawyer's title opinion. The one check that catches most problems.
Checklist
- Verify the title deed and trace the chain of title (~30 years).
- Obtain and read the Encumbrance Certificate.
- Check mutation/khata and up-to-date property tax receipts.
- Confirm approved plan, land-use conversion, and occupancy certificate.
- For under-construction, verify RERA registration and history.
- Get an advocate's written title search report before paying.
Frequently asked questions
What is title due diligence in property? It's the legal verification, before buying, that the seller truly owns the property and can transfer it free of loans, disputes, or defects.
How far back should I check the chain of title? Ideally about 30 years of an unbroken, registered ownership trail.
What is an Encumbrance Certificate? A record from the sub-registrar listing registered transactions on a property, used to confirm there are no mortgages or charges.
Is a general power of attorney proof of ownership? No. A GPA does not convey title; only a registered sale deed transfers ownership.
Do I need a lawyer to buy property? Strongly recommended. An advocate's title search report is the most reliable way to catch defects before you pay.
