The governing law is Chapter 417 of the Revised Statutes of Missouri: section 417.200 declares that every name other than the true name of the person doing business is a fictitious name and makes it unlawful to transact business under one without first registering with the secretary of state.

Unlike states that split the filing between a state office and county clerks, Missouri routes every entity type to the same place: section 417.210 requires every person, general partnership, corporation, or other business organization doing business under a fictitious name to file with the Secretary of State within five days after beginning business under that name.
