A North Carolina single-member LLC operating agreement is a document that establishes the ownership, management, procedures, and policies of a single-member limited liability company. While not required by law in North Carolina, an operating agreement allows the owner to outline their rights and obligations with respect to the company and protect their personal assets from potential company liabilities. Even though the document does not have to be submitted to the state, financial institutions or investors may require a copy to prove the legitimacy of the company. Because the owner is the only signatory, it is recommended that the document is signed in the presence of a notary public.
