A Colorado LLC operating agreement allows the partners (members) of a company to enter its rules and ownership interest. Any binding language that the members agree upon can be included in an operating agreement. Such items include management (manager or member-managed), capital contributions, fiduciary duties, officer designation, and responsibilities of each member.
After the execution of an operating agreement, the members should keep a copy for their own records. It is not filed with any government office.

How to Form an LLC in Colorado (4 steps)
The Colorado Secretary of State requires all entities to operate under a unique business name that is distinct and dissimilar to that of any others currently registered in the State. Therefore it is best to conduct a Name Availability Search prior to filing to guarantee the usage of a name. It is also possible to reserve a name for up to 120 days by filing the Statement of Reservation of Name.

3. Operating Agreement (not required)

An operating agreement may be drafted to outline the rights and duties of the company’s ownership as well as describe each owner’s financial interest (if a multi-member LLC). A single-member LLC can use a document of this nature to prove in court that the entity’s structure is separate from the individual and completely unique to the entity itself. Although the form is not required by State law, it is highly recommended that one be drafted after the LLC has been filed with the Secretary of State.
