Okla. Stat. tit. 12A, § 12A-3-503: Notice of Dishonor

NOTICE OF DISHONOR

(a) The obligation of an indorser stated in subsection (a) of

Section 3-415 of this title and the obligation of a drawer stated in

subsection (d) of Section 3-414 of this title may not be enforced

unless (i) the indorsers or drawer is given notice of dishonor of

the instrument complying with this section or (ii) notice of

dishonor is excused under subsection (b) of Section 3-504 of this

title.

(b) Notice of dishonor may be given by any person; may be given

by any commercially reasonable means, including an oral, written, or

electronic communication; and is sufficient if it reasonably

dishonored or has not been paid or accepted. Return of an

instrument given to a bank for collection is sufficient notice of

dishonor.

with respect to an instrument taken for collection by a collecting

bank, notice of dishonor must be given (i) by the bank before

midnight of the next banking day following the banking day on which

the bank receives notice of dishonor of the instrument, or (ii) by

any other person within thirty (30) days following the day on which

the person receives notice of dishonor. With respect to any other

instrument, notice of dishonor must be given within thirty (30) days

following the day on which dishonor occurs.
