What Is Power of Attorney (POA) in a Demat Account?

A demat account holds your shares in electronic form instead of paper certificates. Along with understanding concepts such as your demat account ledger balance, it is also useful to know what a Power of Attorney (POA) does.

You can operate your demat account yourself. But many brokers ask for a POA so that they can transfer securities from your demat account when you sell them, without needing your signature for every single trade. This permission is limited to specific tasks and comes with safety rules set by regulators.

This article explains how a POA works in a demat account, the rules behind it, the other options you can choose instead, the risks involved, and the newer authorisation mechanisms now available.

A Power of Attorney (POA) is a signed permission that allows your stockbroker or Depository Participant to carry out certain actions on your demat account on your behalf.

In practice, a POA is mainly used for moving shares out of your account when you sell them, so the broker does not need your signature for every single trade. How much the broker can do depends on whether you sign a general or a limited (specific) POA, and on the current rules set by regulators.

Think of it like giving your car to a valet driver. You are giving them permission to park your car, but they do not own the car, and they cannot sell it or drive it anywhere else. Similarly, a POA in a demat account setup simply lets your broker move your shares to the buyer whenever you choose to sell them.

Legal Framework

The use of a POA in demat accounts is governed by the Power of Attorney Act, 1882, along with applicable provisions of the Depositories Act, 1996, SEBI regulations, and operational guidelines issued by NSDL and CDSL.

Since 2022, SEBI has introduced Demat Debit and Pledge Instruction (DDPI) as a structured alternative to POA, restricting broker access strictly to settlement and pledge-related purposes.

POAs may be categorised as general or specific based on the scope of authority defined in the document.

General POA

Historically, some brokers obtained broader POAs. Current SEBI regulations require any POA obtained by brokers to be limited in scope and prohibit unrestricted authority. This may include:

• Settlement-related debit of securities

• Historically included broader operational rights, which are not aligned with current regulatory preference.
   

This form of POA is less prevalent today due to its broader permissions, which increase exposure to misuse if not appropriately restricted.

Specific POA

Specific POAs, also referred to as Limited POAs, restrict broker authority to predefined operational functions, such as:

• Debiting securities for stock exchange trades

• Settling trades executed through the broker's own platforms
   

Limited-authority POAs have traditionally been used for settlement-related activities. However, many brokers now offer DDPI instead of POA.

Granting a Power of Attorney is not a regulatory requirement for operating a demat account.

Regulatory Requirements

SEBI guidelines state that granting a POA is not compulsory for opening a demat account. Investors can choose not to issue a POA and still operate their accounts. In the absence of a POA, brokers may require transaction-specific authorisations through alternative mechanisms such as CDSL TPIN.

Alternatives to POA

In place of a POA, account holders may authorise transactions through the following mechanisms:

• CDSL TPIN: CDSL TPIN enables account holders to authorise the debit of securities electronically for eligible transactions without granting a POA.

• DDPI (Demat Debit and Pledge Instruction): A SEBI-introduced framework (2022) that permits limited authorisation for settlement obligations and pledge instructions only.

Execution of a POA follows a standard documentation and verification framework administered by brokers or Depository Participants. This typically involves submission of a prescribed authorisation form along with supporting identification, with scope defined in the POA document.

Documentation commonly recorded includes:

• Copy of PAN card

• Aadhaar card or address proof

• Completed and signed POA document

Settlement-related Transfer of Securities

Lets the broker move shares out of your account after you complete a trade, without asking for your signature every single time, based on what the POA allows.

Remote Account Administration

Permits authorised account operations on behalf of the account holder, where permitted under the POA.

Participation in Public Offers

Where explicitly authorised, POA may allow submission of IPO or public issue applications through broker platforms.

Signing a full POA is no longer the only way to let your broker move your shares. SEBI has introduced two newer, simpler systems that give you more day-to-day control.

TPIN is a transaction authorisation mechanism used along with OTP verification for eligible transactions. Each time you want to sell shares, you get a short code on your phone, and you use that code to approve the sale yourself. No standing paper authorisation is needed.

DDPI (Demat Debit and Pledge Instruction) is an authorisation framework that allows brokers to debit securities only for settlement obligations and pledge-related purposes. It provides a limited authorisation framework for specified purposes.

Both options mean you do not have to hand over a broad, standing signature document just to sell your shares.

POA arrangements involve delegation of operational authority and therefore carry defined risk considerations.

Potential Risks:

• Misuse: Broad authorisations may expose securities to unauthorised activity if controls are inadequate.

• Fraud: Improper use of POA may result in unauthorised pledging or transfer of holdings in isolated cases where internal controls fail.
   

Security and Monitoring Methods:

• Limited-scope POAs restrict broker permissions to settlement-related activities only

• Depository statements reflect account movements

• Transaction alerts issued by depositories indicate debit or credit activity

Revocation Process:

POA revocation typically involves submission of a written request to the broker or Depository Participant, followed by confirmation of deactivation in account records. Acknowledgement of revocation is generally issued as part of the broker's internal compliance process.

Modifying POA Terms:

Changes to POA scope require execution of a fresh authorisation document. Existing POAs cannot be partially amended and must be formally revoked before replacement.

Power of Attorney arrangements in demat accounts form part of legacy operational frameworks that allow brokers to perform settlement-related actions on behalf of account holders. Regulatory developments have introduced alternatives such as DDPI and TPIN, which provide more narrowly defined authorisation mechanisms.

POA remains optional under current regulations and operates alongside these newer structures. Differences across these mechanisms relate primarily to scope of access and authorisation controls. Account holders typically rely on defined permissions and depository-level alerts to monitor activity.
