2011 ORS § 294.027¹
Provisions relating to warrants and payment of claims
(1) In addition to any other provisions of law for the issuance and payment of warrants of any municipal or quasi-municipal corporation or civil subdivision of this state other than school districts, the governing body thereof may by resolution authorize such practices with respect to the form, issuance, delivery, indorsement and payment of warrants as it shall deem convenient, efficient and in the public interest, conforming substantially to those specified in subsection (1) or (2) of this section or in ORS 294.028 (Payment of warrants by depository).
(2) Such governing body may authorize the use of check-warrant forms, to be drawn by its appropriate warrant issuing officer or officers upon the custodian of its funds, so prepared that such custodian may, by subscribing a direction to the depository of such funds to pay the same to the order of the payee, convert the instrument to a check or, by subscribing an indorsement that such warrant is not paid for want of funds, convert the same to an interest-bearing warrant and such governing body may direct that such check-warrants shall not be delivered to the payees therein named until such direction or indorsement shall have been subscribed by the custodian of its funds.
(3) Such governing body may provide that when funds are available for the payment of approved claims, the approval of claims for payment shall, without the issuance of any warrant, be authority to the custodian of its funds to pay such claims by check. [1953 c.664 §1]
