Ala. Code § 9-9-54

Any warrant issued under this article that is not paid when presented to the treasurer of the district because of lack of funds in the treasury shall be endorsed on the back of said warrant “not paid for lack of funds.” Such warrant shall draw interest thereafter at the rate of six percent per annum until such time as there is money in hand to pay the amount of such warrant and the interest then accumulated. The treasurer shall list such warrants in the order in which they are presented and reserve the funds that may be collected for the payment thereof to be applied to the retirement of the warrants in such order. No such warrant shall draw interest after the time when sufficient funds are in the hands of the treasurer to pay such endorsed warrant and interest.
