Do you accept POA's as signors on CIP forms? What additional documentation should be required on these?
CIP requires you have reviewed enough information to "Form a reasonable belief that you verified the individuals identity & know it is really them", and
there is no requirement for the customer to sign.You should verify the identity of the account owner (who is issuing the Authority because they own the account - the 2nd party has just been given authority by the owner)
So if your bank policy is to require the customer to sign a form that is your internal decision.
