Rights and Obligations of the Investor

Brokers act as your intermediary to the exchange and are governed by strict market standards:
Obligation to Issue Contract Notes: Brokers must issue contract notes for all trades within one working day of execution.
Margin Statements: They are required to send daily margin statements and maintain client data with the highest confidentiality (unless legally compelled to disclose).
Right to Liquidation: If a client fails to pay required margins, the broker reserves the right to close out or liquidate the client's positions to recover the balance.
No Forced Authorization: Brokers cannot compel clients to sign a Power of Attorney (PoA) or a Demat Debit and Pledge Instruction (DDPI), nor can they deny basic trading services if the client refuses these specific authorizations.

DPs serve as the direct link between you and the depositories (such as NSDL or CDSL):
Obligation of Authorization: DPs can only transfer securities to or from your Demat account based on your explicit, authorized mandate.
Statements of Account: DPs must provide regular account statements. If your account has no activity, they must send a physical statement at least annually.
Right to Close Account: DPs have the right to close your Demat account (e.g., for rule violations) with a written notice of at least 30 days.
Beneficiary Rights: As the account holder, you have the right to close your account at any time without charge (provided all outstanding dues are cleared), and transfer your balances to another DP. For comprehensive, legally binding details regarding your specific trades, you can review the official SEBI-mandated Rights and Obligations of Beneficial Owner and Depository Participant document.
