A Missouri single-member LLC operating agreement is a legal document used to establish the sole ownership and internal procedures of a limited liability company. Typically implemented after the formation of an LLC, the operating agreement is required by Missouri law for a company to operate in the state. In addition, the operating agreement helps to maximize the owner’s protection from company-related legal issues or financial obligations by formally declaring the LLC as a separate entity. It is highly recommended that the document is timestamped and notarized upon completion.
