     § 3403.  Unauthorized signature.
        (a)  Ineffectiveness or ratification.--Unless otherwise
     provided in this division or Division 4 (relating to bank
     deposits and collections), an unauthorized signature is
     ineffective except as the signature of the unauthorized signer
     in favor of a person who in good faith pays the instrument or
     takes it for value. An unauthorized signature may be ratified
     for all purposes of this division.
        (b)  Signature of organization.--If the signature of more
     than one person is required to constitute the authorized
     signature of an organization, the signature of the organization
     is unauthorized if one of the required signatures is lacking.
        (c)  Liability.--The civil or criminal liability of a person
     who makes an unauthorized signature is not affected by any
     provision of this division which makes the unauthorized
     signature effective for the purposes of this division.
