A certified copy of the resolution excluding the territory shall be forthwith transmitted to the division of local government in the department of local affairs, and three certified copies shall be forthwith transmitted to the clerk of the municipality, and the clerk of the municipality shall cause a certified copy of the resolution to be recorded in the county or counties in which the municipality is located and a copy thereof delivered to the office of the county assessor and county treasurer of each county in which the excluded territory is located. Additional certified copies of such resolution shall be issued by the secretary of the district upon request.
