Transmission of Shares After Death of a Demat Account Holder: Process, Documents & Rules

Losing a loved one is difficult enough without the added burden of navigating complex financial paperwork. Yet, for many Indian families, the question of what happens to shares held in a deceased person's demat account is one they're entirely unprepared for.

If a family member held investments in a demat account and has passed away, those securities do not simply vanish, nor do they transfer automatically. There is a defined legal process for this, known as the transmission of securities. Understanding it clearly can save families weeks of confusion and paperwork during an already difficult time.

This guide walks you through everything you need to know: what the transmission of shares means, how it differs from a regular transfer, the required documents, the rules governing the process, and what to do in different situations.

What is the Transmission of Securities?

The term "transmission of securities" refers to the transfer of ownership of shares (or other securities) from the account of a deceased holder to a legal heir, nominee, or surviving joint account holder, not through a voluntary act, but by operation of law.

As NSDL (National Securities Depository Limited) explains, while a transfer of shares involves a voluntary act by the shareholder (like selling or gifting), transmission is triggered by events such as death, succession, inheritance, or bankruptcy. There is no transfer deed involved; instead, the process relies on documents like a death certificate and legal heirship proof.

In the older system of physical share certificates, this was a notoriously cumbersome process. Families had to contact each individual company whose shares the deceased held, send physical documents by post, and follow up separately, sometimes with dozens of companies. The risk of loss, delay, and error was significant.

The depository system, through NSDL or CDSL (Central Depository Services Limited), has made this significantly simpler. Since the securities are held electronically in a demat account, the successor needs to deal with only one entity: their Depository Participant (DP), which is typically a bank or broker through whom the demat account was opened.

Transmission of Shares vs. Transfer of Shares: Key Difference

It is important not to confuse these two terms, as they have very different legal meanings.

Transmission of shares does not attract stamp duty, which is an important distinction from a regular share transfer.

Three Scenarios: Who Claims the Securities?

The transmission process differs depending on how the demat account was held. There are three common scenarios:

1. Jointly Held Account (One Holder Passes Away):

If the demat account was held jointly and one of the holders passes away, the surviving holder(s) can request the DP to transmit the securities to an account in the name of the surviving holder(s). This is relatively straightforward.

Documents typically required:

• Transmission request form (available from your DP)
• Notarised copy of the death certificate
• A demat account for the surviving holders (can be with the same or a different DP)

2. Singly Held Account with a Nominee:

This is the simplest case among sole-holder situations. If the deceased had registered a nominee at the time of opening the demat account (or later), the nominee can claim the securities with minimal paperwork.

Documents typically required:

• Transmission request form
• Certified copy of the death certificate
• Proof of identity of the nominee
• Client Master List (CML) of the nominee's demat account, attested by their DP

The significant advantage here is that no succession certificate, probate, or court order is required. NSDL confirms that when a nomination has been made, the need for cumbersome legal documentation is eliminated entirely for the nominee.

Important note: The nominee receives the securities as a trustee on behalf of the legal heirs. This means the nominee is not necessarily the permanent owner; legal heirs may have a separate claim under personal law. However, the transmission itself happens smoothly and quickly.

3. Singly Held Account Without a Nominee:

This is the most documentation-intensive scenario. When a sole holder passes away without a registered nominee, the legal heir(s) or legal representative(s) must approach the DP with the required documents.

Documents typically required:

• Transmission request form
• Notarised copy of the death certificate

One of the following:

• Notarised copy of the Succession Certificate, or
• Notarised copy of Probate of Will or Letter of Administration

Simplified Transmission: The Threshold-Based Process

Recognizing that obtaining a succession certificate or probate can be time-consuming and costly, SEBI has established a simplified process for cases where the value of securities is below a certain threshold, making the system more accessible, especially for middle-income families.

Current Thresholds (as of 2025)

Under SEBI's current rules, the threshold for simplified documentation in demat accounts (single holder, no nominee) is ₹15 lakh per beneficiary-owner account.

If the value of securities in the deceased's demat account is up to ₹15 lakh, the legal heir can claim them without a succession certificate or probate by submitting:

1. Transmission request form
2. Notarised copy of the death certificate
3. Letter of Indemnity (on appropriate non-judicial stamp paper, supported by an independent surety acceptable to the DP)
4. Affidavit (on appropriate non-judicial stamp paper)
5. No Objection Certificates (NOCs) from all other legal heirs who do not object to the transmission

If the value exceeds ₹15 lakh, the full set of legal documents (succession certificate/probate/letter of administration) will be required.

What's Changing: SEBI's Proposed Reforms (2026)

In March 2026, SEBI released a consultation paper proposing significant further simplification. The regulator acknowledged that current thresholds, set years ago, no longer reflect the sharp rise in portfolio values. Key proposals include:

1. Raising the simplified documentation threshold for demat holdings from ₹15 lakh to ₹30 lakh
2. Introducing Straight-Through Processing (STP) for very small claims, up to ₹30,000 for demat securities, requiring minimal documentation
3. Processing timeline: Transmission requests are to be completed within 21 calendar days of receiving all required documents
4. Standardized forms and online tracking are to be made available by all intermediaries
5. Mandatory acknowledgment of claim receipt, with reasons to be given in case of rejection or delay

Note: These proposals are currently under public consultation and have not yet been formally implemented as of the date of this blog. Readers should check SEBI's official website or consult their DP for the latest applicable rules.

Step-by-Step Process: How to Initiate Transmission of Shares in a Demat Account

Here is a practical walkthrough of the process from start to finish:

Step 1: Identify the DP -

Find out which Depository Participant (bank or broker) the deceased decided to open demat account with. Check past account statements, emails, or contact NSDL/CDSL's helpline if needed.

Step 2: Download the Transmission Request Form - 

The transmission form is available on the DP's website or at their service center. It will ask for details of the deceased's account, the claimant's details, and the securities to be transmitted.

Step 3: Gather the Required Documents -

Depending on whether a nominee exists and the value of the holdings, compile the relevant documents as described in the sections above.

Step 4: Submit Documents to the DP -

Submit the completed form along with all supporting documents to the DP's office or service center. Some DPs also offer online or courier-based submission.

Step 5: DP Verification -

The DP will verify the documents for completeness and authenticity. They may request additional documents if required.

Step 6: Transmission Executed -

Once satisfied, the DP will transfer the securities from the deceased's account to the claimant's demat account. The deceased's account is then closed.

Step 7: Account Needed for the Claimant -

The person receiving the securities must have their own demat account. If they don't have one, they will need to open a demat account before the transmission can be completed.

Why Does Having a Nominee Matter So Much?

This is perhaps the single most important takeaway from this entire guide: registering a nominee in your demat account makes an enormous difference for your family.

Without a nominee, your heirs will need succession certificates or probate orders, documents that can take months (sometimes years) to obtain from courts, involve legal costs, and create significant family stress during bereavement.

With a nominee, the process is reduced to submitting a death certificate and a transmission form. That's it.

SEBI mandates that all DPs provide and publicize the nomination facility. If you currently have a demat account and have not registered a nominee, it is strongly advisable to do so. Most DPs allow you to add or update a nominee online or at the service center.

Transmission for Physical Share Certificates (Non-Demat)

While this guide primarily covers demat accounts, it is worth noting that many older investors still hold physical share certificates. The transmission process for physical securities is more cumbersome, requiring documents to be sent to each company individually.

For physical holdings:

• With a nominee: Submit the prescribed form and death certificate to the company's Registrar and Transfer Agent (RTA)
• Without a nominee, value up to ₹5 lakh: Simplified documentation (affidavit, indemnity bond) is accepted
• Without a nominee, value above ₹5 lakh: Succession certificate or probate required

SEBI has consistently encouraged investors to dematerialize their physical shares to avoid such complications. Converting physical certificates into demat form simplifies both regular trading and, in the event of death, the transmission process.

Tax Implications of Transmission of Shares

Transmission of shares to a legal heir or nominee is not treated as a transfer under the Income Tax Act, 1961. Therefore, it does not attract capital gains tax at the time of transmission itself.

However, when the heir/nominee subsequently sells those shares, capital gains tax will be applicable. 

In such cases:

• The original cost of acquisition (the price at which the deceased purchased the shares) is considered for calculating gains
• The holding period includes the period during which the shares were held by the deceased

It is advisable to consult a qualified tax professional or chartered accountant for personalized guidance on the tax treatment of inherited securities.

Common Mistakes to Avoid

• Not registering a nominee: As explained above, this single omission can significantly complicate the transmission process.

• Waiting too long to initiate the process: Securities remain frozen in the deceased's account. Dividends and corporate benefits may be affected. Initiate the process at the earliest.

• Submitting incomplete documents: DPs will reject or delay incomplete applications. Double-check every document before submission.

• Not having a demat account as the claimant: If the nominee or legal heir does not have a demat account, the securities cannot be transmitted until one is opened.

• Assuming securities transfer automatically: They don't. The transmission process must be actively initiated by the claimant.
