Mont. Code Ann. § 85-7-1508

The member of the board acting as secretary or any person appointed by the board as secretary for the district must receive compensation for services as allowed by the board. It is the duty of the secretary to keep the books and records of accounts, contracts, securities, and other records, to perform the duties promptly each month, and to make a monthly reconcilement of accounts with the county treasurer. It is the duty of the county treasurer to make a monthly report to the secretary of all receipts, disbursements, and balances. A failure by the secretary to comply with the provisions of this section causes a forfeiture of the secretary's salary, and the secretary must be removed from office by the board.
