(a) A bank in the county that wants to be a county depository must deliver its application to the county judge or a designated representative of the judge on or before a date set by the commissioners court that is no later than the 60th day before the date of the expiration of the existing depository contract.
(b) The application must state the amount of the bank’s paid-up capital stock and permanent surplus, and the application must be accompanied by:
