Lost the Share Certificate? What SEBI's Special Window Can and Can't Do

The special window has one condition that stops a lot of buyers. You must produce the original share certificate. SEBI's eligibility matrix marks every case without it as ineligible, whether or not the transfer deed was ever lodged.

Why the certificate matters so much

A transfer deed shows that the seller agreed to sell. The certificate is what identifies the shares that were sold. Without it, a registrar can't rule out that the same shares were sold to someone else, reported lost by the seller, or already replaced with duplicates.

A buyer cannot apply for duplicates

Duplicate shares are issued to the person on the company's register of members, or to their legal heirs after transmission. A buyer whose transfer was never registered is not on the register, however clearly the deed shows the sale. So you cannot apply for duplicates in your own name.

Routes that may still be open

• The seller is alive and willing to help: the seller applies for duplicate shares, which under the December 2025 rules are credited to the seller's demat account, and then transfers them to you. That is a fresh transaction between you, with its own tax and stamp duty, so have it properly documented.
• The seller has died: the seller's heirs would first need the shares transmitted to them, with the missing certificates dealt with as part of that, and then transfer them to you. It needs the heirs' goodwill and some patience.
• Nobody can be found, or nobody will help: we don't know of an administrative route. What remains is legal, and the window's own circular points disputes to a court or the NCLT. Whether that is worth pursuing depends on the value, so take a lawyer's view before spending money.

Make sure it is really lost

Before ruling out the window, check:

• The registrar's old objection memo or covering letter, if your transfer was rejected. It may say whether the certificates were returned to you.
• Bank lockers, and the papers of whoever in the family handled the purchase
• The broker who arranged the purchase, if the firm still exists
• The registrar's own records. Write in, quoting the folio, certificate and distinctive numbers, and ask whether any certificates were retained after an earlier lodgement.

If the shares are already in your name

This page is for buyers. If the shares are registered in your name, or a deceased parent's, and only the certificate is missing, you don't need the window. That is the ordinary duplicate share process, which SEBI simplified in December 2025: lost share certificates and duplicate shares.
