Mo. Rev. Stat. § 543.270: Fine payable in installments.

When a fine is assessed by a municipal judge, associate circuit judge, or circuit judge, it shall be within his or her discretion to provide for the payment of the fine on an installment basis under such terms and conditions as he or she may deem appropriate. In no event shall the recovery of costs incurred by a municipality or county for the detention, imprisonment, or holding of any person be the subject of any condition of probation, nor shall the failure to pay such costs be the sole basis for the issuance of a warrant.
