It is the largest 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 three floors nobody ever got approved.
Title due diligence is verifying, before any money moves, that the seller owns what they are selling and can transfer it free of trouble — the title deed, the chain of ownership back about 30 years, an Encumbrance Certificate, mutation and tax records, the approved plan, and an advocate's written title opinion.
The bottom line
What to verify: the title deed and the chain of ownership through the mother deed, an Encumbrance Certificate showing no loans or charges, mutation records and property tax receipts, the approved building plan and land-use conversion, and RERA registration for anything under construction.
Who should do it: a property advocate, issuing a written title search report.
What never counts as ownership: a general power of attorney.
Why this falls on you
The government does not guarantee land titles in India. Registration records that a transaction happened; it does not certify that the seller's ownership was flawless. So the burden of verifying title sits with the buyer, and with nobody else in the chain.
A defective title surfaces years later as a rival claimant, a bank enforcing an old mortgage, or an heir contesting a sale that predates their inheritance. By then unwinding it means slow and expensive litigation. Due diligence is the window in which the problem is still someone else's.
The documents to examine
- The title deed — the current owner's registered document showing how they acquired the property, whether by sale, gift, partition or otherwise.
- The chain of title, or mother deed — the sequence of past transfers, traced back ideally 30 years, confirming an unbroken and clean ownership trail.
- Mutation records, the khata or patta — the revenue or municipal record showing the property mutated in the seller's name, which matters for taxes and for your own future transfer.
- Property tax receipts, paid up to date, which confirm possession and the absence of dues.
- Latest utility bills, as a second check on both.
- For inherited property — the will, succession certificate or legal-heir documents, and NOCs from the other heirs.
- Identity and capacity of the seller — that they are the actual owner and competent to sell, and properly authorised where the seller is a company or a trust.
The Encumbrance Certificate
An Encumbrance Certificate comes from the sub-registrar's office, often online, and lists the registered transactions on a property over a period: sales, mortgages, charges.
A clean EC tells you the property is not mortgaged to a bank or otherwise charged. Where there is an existing home loan, you need the lender's confirmation that it will be cleared and the charge released on sale, in writing, before you pay anything.
Pull the certificate for a period long enough to cover the chain you are verifying, not just the last few years.
Approvals, land use and RERA
A clean title is not enough if the building itself is unlawful.
- The approved building plan from the local authority. Confirm the structure matches what was sanctioned — extra floors or extra coverage are unauthorised however long they have stood.
- Land use and conversion. Agricultural land needs conversion to non-agricultural use before residential or commercial use. Verify it rather than assume it.
- The occupancy or completion certificate for a completed building.
- RERA registration for anything under construction. Check the project and the promoter on your state's RERA portal, including the complaint history.
- Society or builder NOC where applicable, and clearance of maintenance dues.
Get a title search report
This is not a job to do alone. Engage a property advocate to conduct a title search at the sub-registrar's office and issue a written title opinion assessing whether the title is clear and marketable.
Banks insist on exactly this before sanctioning a loan, which tells you what they think of its reliability. Set against the price of the property, a proper title opinion is the cheapest insurance available against buying a lawsuit.
Reasons to walk away
- A GPA sale offered as proof of ownership. A general power of attorney conveys no title.
- A break or a gap in the chain of title that the seller cannot explain.
- An EC showing an unreleased mortgage, with no clear payoff plan behind it.
- A mismatch between the approved plan and the building that is standing.
- Pending litigation, disputed boundaries, or co-owners and heirs who are reluctant to sign.
- Pressure to pay in cash, or to close quickly to avoid paperwork.
A worked example
A buyer likes a resale flat. His advocate traces the chain of title back three decades through successive registered sale deeds, and it is clean.
The Encumbrance Certificate shows one mortgage. The seller's bank confirms in writing that it 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 move to a registered sale deed.
One mortgage could have trapped him. It was found and dealt with before any money moved, which is the entire point of the exercise.
Common mistakes
- Reading the current deed and skipping the chain behind it. One document does not prove a clean history.
- Not pulling an Encumbrance Certificate. Hidden mortgages surface after you have paid.
- Ignoring plan approvals. Unauthorised construction can be penalised or demolished, and it is your problem once you own it.
- Treating a GPA as title. It conveys no ownership.
- Closing without a lawyer's title opinion, which is the single check that catches most problems.
Frequently asked questions
What is title due diligence in property? 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 the 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 conveys no 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.
The seller has a home loan. Is that a dealbreaker? No, provided the lender confirms the charge will be released against the sale proceeds. What you cannot accept is an unreleased mortgage with no written payoff arrangement.
