§12A-8-402.
   
   Assurance that Indorsement or Instruction is Effective.
   
   (a) An issuer may require the following assurance that each necessary
   indorsement or each instruction is genuine and authorized:
   
   (1) in all cases, a guaranty of the signature of the person making an
   indorsement or originating an instruction including, in the case of an
   instruction, reasonable assurance of identity;
   
   (2) if the indorsement is made or the instruction is originated by an
   agent, appropriate assurance of actual authority to sign;
   
   (3) if the indorsement is made or the instruction is originated by a
   fiduciary pursuant to paragraph (4) or (5) of subsection (a) of
   Section 8-107 of this title, appropriate evidence of appointment or
   incumbency;
   
   (4) if there is more than one fiduciary, reasonable assurance that all
   who are required to sign have done so; and
   
   (5) if the indorsement is made or the instruction is originated by a
   person not covered by another provision of this subsection, assurance
   appropriate to the case corresponding as nearly as may be to the
   provisions of this subsection.
   
   (b) An issuer may elect to require reasonable assurance beyond that
   specified in this section.
   
   (c) In this section:
   
   (1) "Guaranty of the signature" means a guaranty signed by or on
   behalf of a person reasonably believed by the issuer to be
   responsible. An issuer may adopt standards with respect to
   responsibility if they are not manifestly unreasonable.
   
   (2) "Appropriate evidence of appointment or incumbency" means:
   
   (i) in the case of a fiduciary appointed or qualified by a court, a
   certificate issued by or under the direction or supervision of the
   court or an officer thereof and dated within sixty (60) days before
   the date of presentation for transfer; or
   
   (ii) in any other case, a copy of a document showing the appointment
   or a certificate issued by or on behalf of a person reasonably
   believed by an issuer to be responsible or, in the absence of that
   document or certificate, other evidence the issuer reasonably
   considers appropriate.
