Answer:
by Randy Carey: I am not sure why not. However, most banks don't open accounts or actually add someone to an account without completing CIP. You might want to revisit your procedures.
Answer:
by Andy Zavoina: I would suggest that just as in the case of a divorce, a new account be opened and this one closed. The bank allowed the person to be on the account, so returning items, paying a check, discussing the account with the non-CIP'd person, etc, will all be difficult. As Randy noted, the bank put the cart before the horse on this one.
