Mo. Rev. Stat. § 382.170
Any person may file with the director a disclaimer of affiliation with any authorized insurer or the disclaimer may be filed by the insurer or any member of an insurance holding company system. The disclaimer shall fully disclose all material relationships and bases for affiliation between such person and such insurer as well as the basis for disclaiming such affiliation. A disclaimer of affiliation shall be deemed to have been granted unless the director, within thirty days following receipt of a complete disclaimer, notifies the filing party that the disclaimer is disallowed. In the event of disallowance, the disclaiming party may request an administrative hearing, which shall be granted. The disclaiming party shall be relieved of its duty to register under this section if approval of the disclaimer has been granted by the director or if the disclaimer is deemed to have been approved.
