An Indiana single-member LLC operating agreement is used by a sole owner to formally establish the objective, rules, and procedures of a limited liability company. The document outlines details regarding ownership, management, meetings, and what happens in the event of dissolution. The operating agreement proves that the company is its own entity that is legally and financially separate from the owner. This means that the owner’s exposure is limited if sued or held liable as the head of the company. Because this document only has one signatory, it should be dated and notarized in order to prove its authenticity.
