What Is an LLC Operating Agreement?
Last reviewed: May 2026
An operating agreement is the foundational legal document that governs how a limited liability company is structured and operated. It defines ownership interests, management structure, profit allocation, decision-making, and what happens when a member wants to leave or the company needs to be dissolved.
Every LLC should have an operating agreement — even single-member LLCs. Without one, the LLC is governed entirely by default state laws, which may not reflect what the owners actually want.
What an Operating Agreement Covers
- Ownership structure — who owns the LLC and in what percentages.
- Management — whether the LLC is managed by its members or by designated managers.
- Voting rights — what decisions require a vote, what constitutes a majority, and whether certain decisions require unanimous consent.
- Capital contributions — what each member contributed at formation and whether additional contributions can be required.
- Profit and loss allocation — how profits and losses are distributed among members.
- Transfer restrictions — whether members can sell their ownership interest, and under what conditions. Most agreements include a right of first refusal.
- Buyout provisions — what happens when a member wants to leave, dies, becomes disabled, or is forced out.
- Dissolution — under what circumstances the LLC can be dissolved and how assets are distributed.
Why You Need an Operating Agreement Even for a Single-Member LLC
An operating agreement reinforces the legal separation between you and your company — essential for maintaining liability protection. It also establishes formal business operations, making clear that you are running a business rather than a sole proprietorship with a different name.
What Happens Without an Operating Agreement
Without one, your LLC is governed by default state statutes — which often require equal profit distribution regardless of contribution, give all members equal management authority, and impose rigid rules about departing members. More importantly, disputes between co-owners have no governing document, making every disagreement a legal battle.
Frequently Asked Questions
Is an operating agreement legally required?
Not in most states, though California, Delaware, Missouri, New York, and Maine legally require LLCs to have them. Even where not required, having one is essential.
Can I write my own operating agreement?
Templates are available online but frequently miss jurisdiction-specific requirements and create ambiguity that leads to disputes. A business attorney can draft one tailored to your situation for a relatively modest fee.
What happens if co-owners disagree and there is no operating agreement?
State law governs — typically equal management authority for all members and no clear mechanism for breaking deadlocks. In practice this often means expensive litigation or forced dissolution.
Can an operating agreement be changed after formation?
Yes. Amendments typically require a vote of the members. Document any amendments in writing and have all members sign them.
Do I need an operating agreement if I am the only owner?
Yes. A single-member operating agreement establishes the separation between you and your company and protects the liability protection that is the reason for forming an LLC.
