The county treasurer is the county's banker.
The county treasurer, as the chief custodian of county finance, shall:
Receive all monies belonging to the county from whatever source;
Keep and account for all monies in a designated depository; and
Pay and apply or disburse all monies in such a manner as commissioners court may direct, by law.
All receipts of any official belonging to the county must be turned over to the county treasurer daily. The county treasurer often acts as the chief liaison between the county and all depository banks. In this capacity, he or she maintains records of all deposits and withdrawals, and reconciles all bank statements, thus assuring their accuracy and the safety of county funds. The county treasurer, who may be designated as the county's investment officer, is required to submit regular reports on county finance to the members of commissioners court to inspect and verify.
