A Louisiana single-member LLC operating agreement is an essential document used internally to establish the ownership, purpose, policies, and procedures of a single-member company. While not required by state law in Louisiana, it can be extremely helpful to establish the rights and responsibilities of the owner with regard to the LLC while limiting the owner’s exposure to company-related debt or litigation. Companies that do not implement an operating agreement are subject to the state’s LLC operating laws. Once completed and signed, the document should be acknowledged by a notary public to prove the date and time of authorization.
