Mo. Rev. Stat. § 207.050
In every county there shall be established a county family services commission to consist of four persons, two from each of the two major political parties, to be selected by the director of social services from a list submitted to the director of the department of social services by the county commission, consisting of double the number of appointments to be made. Each member of the county family services commission shall serve for a term of four years. Vacancies shall be filled in the same way in which the original appointment was made. If the county commission fails or refuses to submit a list to the director of social services as required by this section for the appointment of members of the county family services commission within ten days after such appointments are to be made the director of social services shall make such appointments as may be necessary from a list prepared by the director of social services. The duties of the county family services commission shall be advisory in nature with the power to examine the records of any case pending within their county and to make recommendations thereon. They shall serve without compensation, but shall be paid their traveling expenses and other necessary expense in the performance of their duty. No elective officer shall be appointed as a member of the county family services commission, and upon becoming a candidate for any elective office, such member of the county family services commission shall forthwith forfeit his position on the commission. Duties imposed by this law upon the several county commissions shall be performed in the city of St. Louis by the board of estimate and apportionment.
