Power of Attorney (POA) (Demat)

A Power of Attorney (POA) in the context of a Demat account is a legal document that authorises a stockbroker to operate the investor's Demat account — specifically to debit securities from the account for settlement of sale transactions executed on the exchange, without requiring the investor's explicit instruction for each individual debit. Investors sign a POA in favour of their broker at the time of account opening, enabling the broker to seamlessly settle exchange-executed trades by debiting sold securities directly from the Demat account to the broker's pool account for settlement with the clearing corporation. Under SEBI's regulations, a broker-specific POA can only be used for limited, specified purposes — primarily settlement of exchange trades — and cannot be used to transfer securities to any third party or sell securities without the client's trading instructions. SEBI has progressively tightened POA regulations to prevent misuse by brokers — most notably in 2020, SEBI introduced the pledge-based margin framework as an alternative to POA, allowing investors to avoid giving POA altogether by using the CDSL/NSDL pledge mechanism for margin purposes. Investors should understand the specific scope and limitations of any POA they sign and regularly review their Demat account statements to detect any unauthorised debits.
