Section 3407 - Alteration

     § 3407.  Alteration.
        (a)  Definition of "alteration".--"Alteration" means:
            (1)  an unauthorized change in an instrument that
        purports to modify in any respect the obligation of a party;
        or
            (2)  an unauthorized addition of words or numbers or
        other change to an incomplete instrument relating to the
        obligation of a party.
        (b)  Fraudulent alteration; discharge.--Except as provided in
     subsection (c), an alteration fraudulently made discharges a
     party whose obligation is affected by the alteration unless that
     party assents or is precluded from asserting the alteration. No
     other alteration discharges a party, and the instrument may be
     enforced according to its original terms.
        (c)  Certain persons not affected by discharge.--A payor bank
     or drawee paying a fraudulently altered instrument or a person
     taking it for value, in good faith and without notice of the
     alteration, may enforce rights with respect to the instrument
     according to its original terms or, in the case of an incomplete
     instrument altered by unauthorized completion, according to its
     terms as completed.
