Tex. Bus. & Com. Code Section 3.407
Alteration

(a)

“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)

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)

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:

(1)

according to its original terms; or

(2)

in the case of an incomplete instrument altered by unauthorized completion, according to its terms as completed.
Amended by Acts 1995, 74th Leg., ch. 921, Sec. 1, eff. Jan. 1, 1996.
