Power of Attorney (POA) is a legal document giving legal authority to another person
to operate your account (in this case the Demat account) as per the instructions
contained. POA, though not a mandatory document to be signed, is required for smooth
operation of your Demat account. Whenever you sell shares from your demataccount
or want to pledge them for getting margin for trading, the POA is used to debit
the shares from your Demat Account.
