A Nevada single-member LLC operating agreement is a legal document used by the sole owner of a limited liability company to formally establish the purpose, ownership, management, and policies of the business. Even though Nevada state law does not require companies to implement an operating agreement, it is often required by financial institutions when applying for a loan, obtaining insurance, or creating bank accounts. The document also helps protect the owner’s private assets and accounts from seizure or liquidation in the event of company bankruptcy, litigation, or other obligations. It is recommended that the owner sign the document in the presence of a notary public.
