An internal governance document
State filings create your llc — the Articles of Organization. A Operating Agreement is separate: it governs how your llc operates internally.
State requirements: Most states do not require an LLC to adopt a written Operating Agreement, but it is strongly recommended. Certain states — including California, New York, Delaware, Missouri, and Maine — have specific statutory requirements you should be aware of.
Banking & partners: Many banks request an Operating Agreement before opening a business account, even when it is not filed with the state.
