A North Dakota single-member LLC operating agreement is used by the single owner of a limited liability company to enact internal policies and procedures for the business. The document establishes the company as a legally separate entity from the owner and protects any personal assets from the company’s financial obligations. While North Dakota state law does not mandate the implementation of an operating agreement, it may be required by financial institutions or insurance companies to prove the legitimacy of the company. It is recommended that the document is signed in the presence of a notary public.
