To form an LLC, complete and file your articles of organization (sometimes called a certificate of formation).
Although you do not need to file an LLC operating agreement, this is a core document that defines who owns the LLC, how it will be managed, how the membership will handle profits, and more.
Although many LLCs are formed with a single member or a small number of members, it is still advisable to have a member certificate documenting the ownership stake held by each member.
