Most people form their LLC, get the approval letter, and never think about an operating agreement. That’s a mistake. The operating agreement is what tells courts, banks, partners, and the IRS exactly how your LLC works — and without one, they get to decide for you. Usually not in your favor.

What an Operating Agreement Actually Is

An LLC operating agreement is a legal document that defines how your LLC is owned, managed, and operated. It covers who owns what percentage, how decisions get made, how profits and losses are distributed, what happens when a member wants to leave, and what happens if the LLC needs to be dissolved. It’s not filed with the state — it’s an internal document kept by the members. But it’s every bit as important as your Articles of Organization.

Is an Operating Agreement Required?

A handful of states — California, Delaware, Maine, Missouri, and New York — legally require one. Every other state technically doesn’t. But that’s the wrong framing. The question isn’t whether it’s required. The question is what happens without one.

Without an operating agreement, your LLC is governed entirely by your state’s default LLC statutes. Those defaults were written for the generic case — not your specific situation. If you have a dispute with a partner, the state rules decide. If you want to sell your membership interest, state rules decide. If a member dies, state rules decide. An operating agreement lets you write your own rules before any of that happens.

What Should Be in Your Operating Agreement

• Ownership percentages. Who owns what share of the LLC.
• Management structure. Member-managed (all owners make decisions) or manager-managed (designated managers run day-to-day operations).
• Voting rights. What votes are required for major decisions — and what counts as a major decision.
• Profit and loss distribution. How and when money gets distributed to members.
• Buy-sell provisions. What happens when a member wants out, gets divorced, goes bankrupt, or dies.
• New member admission. Process for adding members in the future.
• Dissolution procedures. How the LLC gets wound down if needed.

Single-Member vs Multi-Member Operating Agreements

Single-member operating agreements are simpler — there’s no ownership split to define, no voting procedures for co-owners. But they still matter. A single-member LLC with a written operating agreement is much harder to pierce in court. It’s evidence that you’re running a legitimate separate entity, not just a personal bank account with a business name. For multi-member LLCs, the operating agreement is even more critical — it’s what prevents partner disputes from destroying the company.
