87. In the case of a representative who is designated by a court, any document issued by or under the direction or supervision of the court or an officer of the court and dated within 60 days before the date of presentation for transfer is appropriate evidence of the representative’s authority to act on the appropriate person’s behalf.
In any other case, a copy of a document showing that the representative has the authority to act on the appropriate person’s behalf, a certificate certifying that authority issued by a person reasonably believed by the issuer to be a responsible person or, in the absence of such a document or certificate, other evidence that the issuer reasonably considers appropriate is appropriate evidence of the representative’s authority to act on the appropriate person’s behalf.
