Missouri Revised Statutes Title XXIII. Corporations, Associations and Partnerships § 347.083. Action or vote without meeting, consent required

Unless otherwise provided in the operating agreement, any action or vote which must be taken at a meeting of the members or managers, as the case may be, may be taken without a meeting if a consent in writing, setting forth the action so taken, is signed by all of the persons entitled to act or vote with respect to such matter. Such consent shall have the same effect as an act or vote of such persons.
