Modifies provisions relating to county treasurers

SB 1366 clarifies the duties of county treasurers in Missouri regarding check-writing and account management. It requires treasurers to only issue checks when sufficient funds exist in the corresponding account and mandates that only the treasurer's signature is authorized on county deposit accounts. The bill prohibits other county officials from being listed as signers on these accounts, while allowing other officers to maintain separate accounts for their specific duties under existing law. This directly affects county treasurers, county depositaries, and county officials handling public funds.
