What documents should be obtained from broker on execution of trade?

You have to ensure receipt of the following documents for any trade executed on the Exchange:

a. Contract note in Form A to be given within stipulated time.

b. In the case of electronic issuance of contract notes by the brokers, the clients shall ensure that the same is digitally signed and in case of inability to view the same, shall communicate the same to the broker, upon which the broker shall ensure that the physical contract note reaches the client within the stipulated time.

It is the contract note that gives rise to contractual rights and obligations of parties of the trade. Hence, you should insist on contract note from stock broker.
