What Happens to Unlisted Shares When the Owner Dies?

Reviewed by Team BuyUnlistedShares Research Desk

Most guides on unlisted shares focus on how to buy them. Far fewer explain what happens to those shares when the holder passes away — even though it is one of the most practical questions a family faces. Unlisted shares held in a demat account do not simply disappear or automatically pass to a spouse; there is a defined process, called transmission, that moves them to a nominee or legal heir. This explainer walks through how transmission of unlisted shares works in India as of 2026, the documents typically required, and how the tax cost basis is treated — as information, not investment or legal advice.

What is transmission of shares?

Transmission of shares is the process by which the ownership of shares passes to a nominee or legal heir on the death of the holder, by operation of law rather than by a voluntary sale. It is different from a transfer, which is a deliberate sale or gift between two living people. Transmission requires no consideration (no purchase price) and is triggered by an event such as death, inheritance, or insolvency.

Because most unlisted shares in India are now held in dematerialised (demat) form, transmission is generally handled through the depository system (NSDL or CDSL) via the deceased holder's Depository Participant (DP) — the broker or bank where the demat account was opened.

Nominee vs legal heir: why the distinction matters

Two situations commonly arise, and they follow different paths:

• A nominee was registered. If the deceased had recorded a nominee on the demat account, the depository process to move shares to that nominee is usually simpler and faster. Importantly, under Indian law a nominee is generally treated as a custodian or trustee of the shares, not necessarily the final beneficial owner. The nominee may still have to hand the shares to the rightful legal heirs as determined by a will or succession law.
• No nominee, or a disputed estate. Where there is no nominee, or the value crosses thresholds set by the DP, additional legal documents such as a probated will, succession certificate, or letter of administration may be required. This process is more involved and can take longer.

Registering a nominee during one's lifetime is one of the simplest steps a holder can take to make transmission smoother for the family — a point regulators have repeatedly emphasised.

The transmission process, step by step

While exact requirements vary by Depository Participant and by the value of the holding, the typical sequence is:

1. Open or identify a demat account for the claimant. The nominee or heir needs their own demat account to receive the shares.
2. Submit a transmission request form (TRF) to the deceased's DP, along with a self-attested copy of the death certificate.
3. Provide identity and relationship proof for the claimant (PAN, KYC documents, and, where relevant, proof of legal heirship).
4. Provide legal documents if required — for example a notarised will, succession certificate, or letter of administration where there is no nominee or the value is above the DP's threshold. In some cases an affidavit, indemnity bond, and no-objection from other heirs are requested.
5. Verification and credit. Once the DP and depository verify the documents, the shares are credited to the claimant's demat account.

For any unlisted shares still held in physical certificate form, transmission is handled by the company's Registrar and Transfer Agent (RTA) rather than the depository, and usually involves dematerialising the holding as part of the process.

How tax cost basis works after transmission

Inheriting shares is not itself a taxable "sale" — India does not levy a separate inheritance or estate tax at present. The tax question arises later, when the heir eventually sells the shares. Two principles are generally relevant:

• Cost of acquisition carries over. For computing capital gains, the heir generally inherits the original holder's cost of acquisition (or the value as determined under the relevant provisions), not the market value on the date of death.
• Holding period includes the original holder's. The period for which the deceased held the shares is typically counted towards the heir's holding period, which matters for deciding whether a later sale is long-term or short-term.

Because unlisted-share taxation has specific rules on holding periods and rates, and because individual estates differ, the exact figures should be confirmed with a qualified tax professional.

Practical tips to make transmission easier

• Register and update nominees on every demat account, and review them after major life events.
• Keep a written record of unlisted holdings — company names, ISINs, demat/RTA details — so heirs know what exists.
• Consider a valid will to reduce ambiguity, especially where there is no nominee or multiple heirs.
• Retain purchase records — original cost and holding dates — because they determine the eventual capital-gains tax when the heir sells.

Frequently asked questions

Do unlisted shares pass automatically to the spouse on death?

No. They must go through the transmission process via the deceased's Depository Participant (or the company's RTA for physical shares). Ownership does not change automatically without this step.

Is a nominee the final owner of the inherited shares?

Not necessarily. A nominee is generally treated as a custodian who receives the shares, but the ultimate entitlement is decided by the will or applicable succession law. The nominee may have to pass the shares to the legal heirs.

Is there an inheritance tax on unlisted shares in India?

As of 2026 India does not levy a separate inheritance or estate tax. Tax typically arises only when the inherited shares are later sold, as capital gains.

What documents are needed for transmission?

Commonly a transmission request form, the death certificate, the claimant's demat and KYC details, and — where there is no nominee or the value is high — legal documents such as a will, succession certificate, or letter of administration. Exact requirements vary by DP.

How long does transmission take?

It varies with the completeness of documents and whether legal proof of heirship is needed. A clean nominee case is usually quicker than a contested or no-nominee estate. Check current timelines with the relevant DP or RTA.

Key takeaways

• Unlisted shares pass to heirs through transmission, a defined legal process — not automatically.
• A registered nominee makes the process smoother, but a nominee is a custodian, not automatically the final owner.
• The heir generally inherits the original cost and holding period, which govern capital-gains tax on a later sale.
• Registering nominees, keeping records, and having a will are the simplest ways to protect a family.
