Okla. Stat. tit. 70, § 70-5-185: When check or warrant due – Enforcement of liability

Without regard to the time when funds may be collected and are

available to pay a check or warrant issued by a school district, any

school district check or warrant shall be due one (1) year after the

close of the fiscal year for which the check or warrant was issued

and action may be commenced in any court of competent jurisdiction

to enforce the liability evidenced by the check or warrant. Any

action to enforce the liability evidenced by the check or warrant

shall thereafter be barred, and the lapse of time need not be

asserted as defense in any action for the school district to be

relieved of liability.
