Montana Title 7. Local Government § 7-6-201. Deposit of public funds in financial institutions

(1) Except as provided in 7-6-202, 7-6-206, or 7-6-2701, it is the duty of all county and city treasurers and town clerks to deposit all public money in their possession and under their control only in solvent banks, building and loan associations, savings and loan associations, or credit unions, subject to national supervision or state examination as the local governing body may designate.

(2) The local governing body may deposit public money not necessary for immediate use by the county, city, or town in a savings or time deposit with any bank, building and loan association, savings and loan association, or credit union authorized in subsection (1) or in a repurchase agreement as authorized in 7-6-213.

(3) The treasurer or town clerk shall take from the bank, building and loan association, savings and loan association, or credit union security that the local governing body may prescribe, approve, and consider fully sufficient and necessary to ensure the safety and prompt payment of all deposits, together with the interest on any time or savings deposits.

(4) All deposits must be subject to withdrawal by the treasurer or town clerk in amounts that may be necessary from time to time. A deposit of funds may not be made or permitted to remain in any bank, building and loan association, savings and loan association, or credit union until the security for the deposit has been first approved by the local governing body and delivered to the treasurer or town clerk.
