No purchase deed? You can still prove your cost

By Parish Rao · 24 August 2026 · 6 minute read

This is the most common worry we hear from families selling an old property. The papers are missing, and everyone assumes the tax will be calculated as if the property cost nothing. That is not how it works.

The fear, and why it is misplaced

A house has been in the family since 1972. The original registry paper is gone, or torn, or with a cousin nobody speaks to. The family is about to sell and someone says the dreaded sentence: without the purchase deed, the tax department will treat your cost as zero.

It will not. The law has a separate route for old property, and that route does not depend on your purchase papers at all.

The rule that saves you

For any property acquired before 1 April 2001, the law lets you use its market value on that date as your cost, instead of what was actually paid. That value is established by a valuation report, not by your old deed.

So the question stops being "what did we pay in 1972" and becomes "what was this property worth on 1 April 2001". The second question can always be answered, with or without your paperwork.

What a valuer works from instead

When the deed is missing, we build the picture from records that still exist:

• The official rate notified for your colony or area in 2001, from the archive of that year.
• Registered sale transactions of similar properties nearby around that period.
• Property tax receipts, which usually go back decades and prove possession.
• Electricity or water connection records showing when the building existed.
• Mutation entries and municipal records naming the family.
• Society share certificates and old maintenance receipts, for flats.
• The physical property itself, inspected and measured today, with its age assessed.

None of these is your original deed. Together they are usually stronger evidence than a single yellowed page, because they come from independent sources.

What if you have nothing at all

Even then it is workable. What matters most is that the property exists, that your family holds it, and that its 2001 value can be evidenced. Possession and municipal records do most of the work. Tell us honestly what survives and we will tell you on the phone whether it is enough, before you pay anything.

The one limit to know

The value you claim for 1 April 2001 generally cannot exceed the stamp duty value of that date. This matters, because it is exactly where an inflated report gets caught. A responsible valuer builds the figure inside that ceiling and shows the working. That is the difference between a report that survives scrutiny and one that invites a notice.

What to do next

Do this before you sign anything with a buyer, not after. Once the sale is registered, your tax position is largely fixed, and a valuation done in a panic afterwards is worth far less.

Gather whatever you have, even if it is only tax receipts. Then read what a capital gains valuation involves, or try the free capital gains calculator to see roughly what the 2001 value does to your tax. If your property is outside Delhi, we cover every major Indian city.
