Selling an old Indian house with no cost documents or valuation report

Two problems get tangled together and are worth separating. One is title: the buyer wants to be sure you own the property and can pass clean title. The other is tax: you need a cost to set against the sale price so the gain, and the tax, are not computed on the whole amount. Neither requires the original purchase deed in your hand.

For title, a certified copy of the registered deed can be obtained from the sub-registrar's office where it was originally registered, and the chain of ownership is shown through the encumbrance certificate and, for an inherited property, the succession or legal-heir papers. For tax, the cost is established from whatever reliable record exists, and for an old property the law lets you replace the original price with a much later value, which is where most of the tax actually falls away.

If the property was acquired before 1 April 2001, you do not need the original price at all. You may substitute the property's fair-market value as on 1 April 2001 as the cost (Section 55(2)(b)), and for land or a building that value is capped at the stamp-duty value on that date. A registered valuer fixes it from the circle rates and comparable sales of the period, and because 2001 values sit far closer to today's prices than a 1980s receipt, the measured gain drops steeply.

Where the property was inherited, the date and cost carry from the person you inherited from (Section 49(1)), so a house a parent or grandparent bought before 2001 still qualifies for the 2001 substitution in your hands. If the property was bought after 2001 and the deed is simply lost, the actual cost is reconstructed from the certified copy of the deed, the bank record of the payment, or the loan sanction of the time. The assessing officer can refer a value that looks inflated to a Valuation Officer (Section 55A), which is exactly why a defensible valuer's report matters more than an optimistic round figure.

A house that has had a floor added, rooms rebuilt or a major structural change is worth more than the one that was bought, and the law lets you deduct that spend. Improvements of a capital nature, the added floor, the extension, the new structure, are cost of improvement and come off the sale price along with the cost of acquisition (Section 48). Ordinary repairs, repainting and routine maintenance do not count, so the line is between building something new or lasting and simply keeping the house in order.

The practical trap is proof. Work done years ago rarely has bills, and an NRI abroad cannot reconstruct them easily. A registered valuer can estimate the year-wise cost of the improvements from the approved building plans, the municipal records of the additional construction and the bank or loan records of the period, and that estimate, properly documented, is what the return relies on. One caution: if you have already used the 1 April 2001 fair-market value as the cost, any improvement made before that date is treated as already inside that value and cannot be claimed again.

Rakesh, an NRI in the UK, sells the Nagpur house his father built and bought the plot for in 1994. He inherited it, the original deed is mislaid, and over the years the family added a first floor and rebuilt the kitchen, none of it with surviving bills. He sells in 2026 for eighty lakh.

On the original 1994 cost, almost the whole eighty lakh would be gain. Instead, a registered valuer fixes the fair-market value as on 1 April 2001, within the stamp-duty-value cap, at, say, fourteen lakh, and separately estimates the post-2001 first floor and kitchen work at, say, six lakh of capital improvement. The cost set against the sale becomes about twenty lakh, so the long-term gain is roughly sixty lakh, taxed at the flat 12.5% NRI rate rather than on the gross price. A certified copy of the deed and the valuer's two reports, on the 2001 value and the improvements, are the load-bearing documents, and from here Rakesh can still shelter the gain under Section 54 or 54EC.
