An Operating Agreement is the internal rulebook of your LLC — the document that says who owns what, how profits are split, who makes decisions, and what happens when someone leaves. It's not filed with the state, and it's not required in every state. But it's the single most important document your LLC will ever have.
Why an Operating Agreement matters
Three reasons, in order of importance:
- It protects your liability shield — courts look for evidence that your LLC is a real, separate entity. A signed Operating Agreement is exactly that evidence.
- It fills the legal gaps — without an agreement, your state's default LLC rules apply. Those defaults are designed for generic situations and are often wrong for yours.
- It prevents disputes — the agreement settles the arguments (profit splits, buyouts, deadlocks) before they happen. Multi-member LLCs without one routinely end in litigation.
Who needs one
- Every multi-member LLC — mandatory in practice. If two people own a company, the agreement defines everything.
- Every single-member LLC — still valuable. It reinforces the liability shield, establishes what happens if you pass away, and banks ask for it.
- Required in CA, NY, MO, and ME — even for single-member LLCs.
For a single-member LLC, the agreement is short. For multi-member, it's the constitution of the business.
What it covers
A complete Operating Agreement addresses:
| Topic | What it decides |
|---|---|
| Ownership | Who owns what percentage |
| Distributions | How profits (and losses) are split — and when |
| Management | Member-managed vs. manager-managed |
| Decision-making | What needs a majority, what needs unanimous consent |
| Capital | What each member contributes, and what happens if they don't |
| Buyouts | What happens when a member wants out, dies, or becomes disabled |
| Transfer | Can members sell their interest, and to whom? |
| Deadlock | How a 50/50 company breaks a tie |
Distributions: the part people get wrong
The default assumption is "profits split by ownership percentage." That's often true — but your agreement can (and sometimes should) provide otherwise:
- Disproportionate splits — a managing member might take a higher share.
- Priority distributions — one member gets repaid capital before profit splits.
- Timing — quarterly, annual, or by vote.
If your situation is anything but "equal owners, equal split," the agreement is where you make it explicit.
Management: member-managed vs. manager-managed
- Member-managed — all members have a say in day-to-day decisions. Default for most small LLCs.
- Manager-managed — members appoint one or more managers (who may not be members) to run operations; passive members stay out of daily decisions.
Manager-managed is the right structure when some owners are investors, not operators.
Buyouts: the document that prevents lawsuits
The most expensive disagreement in an LLC is "someone wants out." The Operating Agreement should define:
- How to value the departing member's interest (formula? appraiser? book value?).
- Payment terms (lump sum? installments?).
- Triggering events (voluntary departure, death, disability, bankruptcy, breach).
- Who can buy (the company? other members? outside buyers?).
Without these terms, a departing owner sues to determine the price — and a judge sets it. That's a six-figure outcome controlled by a one-paragraph clause.
Single-member agreements are still worth it
For a one-owner LLC, the agreement is short but not pointless:
- It confirms the member's sole ownership (reinforcing the shield).
- It states what happens on the owner's death or incapacity.
- It answers banks' and partners' questions.
Many one-page single-member agreements exist — but the terms still need to be right for your state.
When to write it
At formation, before you start operating. You can adopt one later, but "later" means the members already have positions to argue about. A signed agreement from day one is a formality; one signed after a dispute starts is a settlement.
Common questions
Is an Operating Agreement required to file? No — it's an internal document. You don't file it with the state. That's why so many LLCs don't have one — and why so many regret it.
Does the state need to see it? Only if you're asked (banks, lawsuits, some registrations). It's not a public filing.
Do I need a lawyer to write it? For standard LLCs, a good state-specific template handled by a competent service is usually sufficient. A lawyer adds value for unusual ownership, real estate, or substantial capital structures.
What's the difference between an Operating Agreement and Bylaws? Bylaws govern corporations; the Operating Agreement governs LLCs. They play parallel roles in the two structures.
Get your rulebook drafted properly
Your Operating Agreement should match your state's laws and your actual ownership situation — a generic template from the internet often doesn't. We draft state-specific Operating Agreements with the ownership, distribution, and buyout terms that fit how your LLC actually works.
