Arizona Revised Statutes Title 11. Counties § 11-145. Payment of costs of county formation

A. All costs of the secretary of state and of the commission under this article are charges against the affected county or counties before their termination and against the new counties after their organization. Costs which can be identified with a specific county shall be charged against that county, but otherwise the costs shall be apportioned between the counties according to their respective assessed valuations.

B. All claims for payment shall be made through the secretary of state to the department of administration. Each month the department of administration shall certify the amounts of the claims to the state treasurer and the treasurer shall withhold and pay the amounts from the monies otherwise payable to the respective counties under § 42-5029, except that the amount withheld shall not exceed one-half of the amount payable to the county in any month. The treasurer shall continue to withhold monies from county payments until all claims under this article are satisfied.
