What Happens to a Demat Account When Someone Dies in India

A demat account does not close automatically when the account holder dies. The shares, bonds, and securities sitting in the account remain held there, and the transmission process - the formal handover to a nominee or legal heir - needs to be initiated by the family. Until that happens, no one can sell or transfer those securities.

This guide explains the complete demat transmission process in India, including the difference between having a nominee and not having one, the practical differences between CDSL and NSDL (the two depositories), what happens to pledged shares, mutual funds held in demat form, and specific steps for major brokers like Zerodha and Groww.

With Nominee vs Without Nominee - Key Differences

Whether a nominee was registered on the demat account determines almost everything about the complexity, cost, and timeline of the transmission process.

Why the Beneficiary Needs Their Own Demat Account First

This is the step that surprises most families. You cannot receive shares into a bank account or as a physical certificate. You can only receive them into a demat account. If the nominee or legal heir does not already have a demat account, they must open one before the transmission request can be filed - not after.

Opening a demat account takes 1 to 5 working days with most online brokers if the KYC documents are in order. The account must be a standard individual demat account (not a joint account) in the nominee's or heir's own name. The demat account can be with any registered depository participant - it does not need to be with the same broker as the deceased's account.

Once the demat account is open, note down the DP ID and Client ID (also called the beneficiary owner account number), as these will be required in the transmission request forms.

The Transmission Process Step by Step

1. Confirm the depository: CDSL or NSDL

   The deceased's demat account is held with either CDSL (Central Depository Services Limited) or NSDL (National Securities Depository Limited). This is shown on the account's DP ID - DP IDs starting with "12" or "16" are typically CDSL, while DP IDs starting with "IN" are NSDL. The broker's website or the holding statement will confirm this.

2. Open a demat account (if the beneficiary does not have one)

   Complete KYC with any registered broker. Resident Indians need Aadhaar and PAN. NRIs need passport, NRO bank account details, and a foreign address proof. Get the DP ID and client ID once the account is activated.

3. Obtain the holdings statement

   A current statement of the deceased's demat holdings shows all securities held. This is available from the broker's customer support team (with a death certificate and your identity proof). The statement confirms what is being transmitted - you cannot initiate transmission for holdings you cannot see.

4. Gather all required documents

   Death certificate, deceased's account details, nominee's or claimant's KYC documents, relationship proof, and the transmission request form. For no-nominee situations, also gather the succession certificate or indemnity bond documentation (see below).

5. Complete the Transmission Request Form (TRF)

   Download the TRF from the broker's website or the depository's website. Fill in the deceased's DP ID and client ID, the beneficiary's DP ID and client ID, details of the claimant, and the list of securities to be transmitted. Submit with all supporting documents to the broker's office or via courier to their document processing address.

6. DP verification and processing

   The depository participant verifies the documents and initiates the transmission with the depository (CDSL or NSDL). This is where most processing time is spent. Online status can typically be tracked through the broker's portal or by contacting their support team.

7. Shares appear in the beneficiary's demat account

   Once the depository approves the transmission, the shares are moved from the deceased's account to the beneficiary's account. The deceased's demat account is then frozen and eventually closed by the DP.

CDSL vs NSDL - Process Differences

Both depositories support demat transmission after death, but there are operational differences in how the process works.

CDSL (Central Depository Services Limited)

CDSL's transmission process is handled through the depository participant (the broker). The TRF is submitted to the DP, who then coordinates with CDSL. CDSL has a digital transmission process (CDSL EASI) that allows some online tracking, but the actual document submission typically goes through the broker. CDSL-registered demat accounts are more common among retail and discount brokers including Zerodha, Groww, Upstox, and Angel One.

NSDL (National Securities Depository Limited)

NSDL's transmission process similarly flows through the DP. NSDL has its own portal (SPEED-e) for some transactions. NSDL-registered accounts are more common among full-service brokers like HDFC Securities, ICICI Direct, and Sharekhan, as well as with banks that offer demat services. The documentation requirements are largely the same between CDSL and NSDL.

The key practical difference

CDSL operates a slightly more centralised verification system, which can sometimes mean faster processing once documents are submitted to the DP. NSDL's process can sometimes involve additional liaison between the DP and the depository for certain types of securities (like unlisted shares). For most standard equity holdings, there is no material difference in the experience.

Documents Required for Demat Transmission

Timeline: 15 to 30 Days

SEBI (Securities and Exchange Board of India) regulations require depository participants to process transmission requests within 7 working days from the date all documents are complete. In practice, the end-to-end timeline (from gathering documents to shares appearing in the beneficiary's account) is typically 15 to 30 calendar days when a nominee is registered and documents are complete.

Without a nominee, the timeline depends primarily on how long it takes to obtain the succession certificate from a civil court - which is typically 3 to 6 months. Once the certificate is obtained, the actual DP processing takes the same 7 to 15 working days.

What Happens to Pledged Shares

Some investors pledge shares from their demat account as collateral for loans or margins with their broker or a bank. When the account holder dies, pledged shares become complicated.

A pledge is a legal encumbrance on specific securities. The pledgee (lender or broker who holds the pledge) has a prior claim over those shares before the nominee or legal heir can receive them. The pledge must be resolved - either by repaying the outstanding loan or margin obligation - before those shares can be transmitted to the beneficiary.

If the estate can repay the loan, the pledge is released and those shares become part of the normal transmission. If the outstanding amount cannot be repaid, the pledgee (lender) has the right to invoke the pledge and sell the shares to recover the debt. The balance, if any, after settling the loan would then be available for transmission.

The family should contact the broker or bank as soon as possible after the account holder's death to understand the pledge status and the outstanding amount. Do not wait - brokers have the right to liquidate pledged shares to cover outstanding positions if they are not notified promptly of the account holder's death.

Joint Demat Accounts

If the deceased held the demat account jointly with another person, the process depends on whether the deceased was the first holder or a joint holder.

If the deceased was the first holder

The surviving joint holder can request the account to be converted to a single-holder account in their name. This is done by submitting a transmission request along with the death certificate to the DP. The surviving holder does not need to transfer the shares to a new demat account - the existing account simply continues with their name as the sole holder. This is faster than a nominee transmission because the surviving holder is already verified with the DP.

If the deceased was a joint holder (not the first holder)

If the first holder is alive and the deceased was a second or third holder, the account continues in the name of the first holder. The DP will update records to remove the deceased's name once the death certificate is submitted. No transmission to a new account is required.

Either or survivor accounts

Most joint demat accounts in India are structured as "either or survivor" - meaning either holder can operate the account independently. In practice, this is the standard operating instruction for joint demat accounts. On the death of either holder, the surviving holder retains full control and ownership without any additional court process.

Mutual Funds Held in Demat Form

Mutual fund units can be held in two ways: in a demat account (where they appear as securities in the demat holdings) or directly with the registrar-transfer agent (RTA) such as CAMS or KFintech (where they are held under a folio number).

If mutual fund units are held in demat form, the transmission process is the same as for shares - the units are transferred through the DP via the standard transmission request process. The units move to the beneficiary's demat account.

If the same fund house's units are also held in physical folio form (outside demat) under the same investor's name, those are separate holdings and follow a different transmission process through the RTA - not through the broker or DP. The demat transmission only covers what is in the demat account; folios held outside demat are a separate matter entirely.

It is common for investors to have the same mutual fund in both demat and folio form (due to switching platforms over the years). Always check both the demat holdings and the CAMS/KFintech folio statement for a complete picture.

Broker-Specific Processes: Zerodha and Groww

Full-service brokers (HDFC Securities, ICICI Direct, Kotak)

Full-service brokers typically operate NSDL accounts and often allow branch-based submission of transmission requests. Many have dedicated relationship managers who can assist the family through the process. Processing timelines are similar - 10 to 20 working days. An advantage of full-service brokers is that their branch staff is often more familiar with the transmission process and can flag missing documents before submission.

Bank-linked demat accounts (SBI Demat, HDFC Bank Demat)

Some investors hold demat accounts directly through their bank rather than through a standalone broker. These accounts work the same way for transmission purposes, but the submission goes to the bank's demat services department rather than a broker. Contact the bank branch where the demat account was opened to initiate the process.

Common Mistakes to Avoid

Trying to sell shares before completing transmission

Once the account holder dies, the demat account is legally frozen. Attempting to sell shares from the deceased's account (including by using their credentials) is illegal and will result in the broker flagging and blocking the account. Wait for transmission to complete before making any decisions about the securities.

Not opening a demat account before filing the transmission request

As noted earlier, the beneficiary's DP ID and client ID are required in the transmission request form. You cannot submit the form without these details, which means the beneficiary's demat account must be active before you initiate the process. Starting the account opening process early saves time.

Submitting incomplete document sets

DPs will reject or return incomplete submissions. Every missing document adds 1 to 2 weeks to the timeline. Download the exact checklist from the specific broker's website and verify every item before couriering the package.

Ignoring pledged shares

Failing to notify the broker promptly about the death when shares are pledged can result in the broker invoking the pledge and selling the shares without the family's input. Always contact the broker within the first week if there are any outstanding obligations on the account.

Assuming nomination covers everything

The demat nominee and the mutual fund folio nominee are separate. Having a nominee on the demat account does not automatically cover mutual fund folios held outside demat, and vice versa. You need to check each type of holding independently.

Using an incorrect death certificate

DPs require the official government-issued death certificate (from the municipal corporation or gram panchayat). A hospital-issued death notice or informal certificate is not accepted. Ensure you have the official certified copy before initiating the process.
