A Colorado single-member LLC operating agreement is an important document created after the formation of a limited liability company (LLC) owned by one person. It outlines details regarding the company’s internal operations, management, and ownership, establishing the LLC as a separate entity from the owner both legally and financially. While Colorado does not require LLCs to create an operating agreement, it allows the owner to determine the company’s rules rather than being subject to state laws governing LLCs. In addition, having an operating agreement as a single-member LLC invites more credibility from potential investors and institutions. It is highly recommended that the document is acknowledged by a notary public in order to prove the time and date of its authorization.
