Generally the person requesting the account to be opened signs the certification, regardless of whether they're listed on the form. There's no requirement that the control person or a beneficial owner sign .

My apologies but have one more question relating to Chapter 7, 11 or 13 accounts where the trustee is court-appointed, is the trustee required to sign the BO form as the controlling party? or are these accounts exempt since the trustee is court-appointed?
