An LLC operating agreement is the internal document that defines how your LLC is owned, managed, and operated. Think of it as the rulebook for your business — it covers everything from who owns what percentage to what happens if a member wants to leave or the business needs to shut down.

Most states don't legally require an operating agreement, but operating without one is one of the most common mistakes new LLC owners make. Here's why it matters and what yours should include.

What Is an Operating Agreement?

An operating agreement is a legal document — typically 5 to 20 pages — that establishes the rules governing your LLC's internal operations. It's a private document between the LLC's members (it does not get filed with the state), and it covers:

Why You Need One (Even for Single-Member LLCs)

1. It Protects Your Limited Liability

The entire point of an LLC is separating your personal assets from your business liabilities. If you're ever sued and a plaintiff argues that your LLC is just an "alter ego" (a legal theory called "piercing the corporate veil"), one of the factors courts consider is whether the LLC was operated as a genuine separate entity.

An operating agreement demonstrates that you treated the LLC as a real business with formal governance — not just a name you filed with the state. Courts in all three of Entity Lane's states (NM, NC, GA) have considered the presence or absence of an operating agreement when evaluating veil-piercing claims.

2. It Overrides State Default Rules

Every state's LLC act includes default rules that apply when members haven't agreed otherwise. These defaults may not match what you want. For example:

3. Banks May Require It

Many banks ask for a copy of your operating agreement when you open a business bank account. It verifies who has authority to manage the LLC's finances, who can sign checks, and who is authorized to make transactions. Without one, opening a bank account can be more difficult.

4. It Prevents Disputes

For multi-member LLCs, an operating agreement is your pre-negotiated resolution to disputes. What happens if members disagree on a major decision? What if one member stops contributing? What if someone wants out? Addressing these scenarios in writing, when everyone is on good terms, is far cheaper and less painful than litigating them later.

State Requirements: NM, NC, and GA

State Operating Agreement Required? Relevant Statute Notes
New Mexico Not legally required NMSA 1978, Chapter 53, Article 19 NM's LLC Act allows operating agreements but doesn't mandate them. State defaults apply in absence of one.
North Carolina Not legally required NCGS Chapter 57D NC's LLC Act is explicitly a "default rules" statute — it provides a comprehensive set of default rules that apply unless your operating agreement says otherwise. NC strongly encourages having one.
Georgia Not legally required O.C.G.A. Title 14, Chapter 11 Georgia's LLC Act recognizes the operating agreement as the primary governing document. Default rules apply to anything not addressed in it.

While none of these three states legally mandate an operating agreement, all three have LLC statutes that defer to operating agreements when they exist — meaning your agreement takes priority over state defaults on most matters.

Important note: Some states, like California, Maine, Delaware, and New York, do require operating agreements (or the equivalent) by law. Even in those states, enforcement of the requirement is rare, but it underscores that legislatures consider operating agreements important enough to mandate.

Single-Member vs. Multi-Member Operating Agreements

Single-Member LLCs

If you're the sole owner, your operating agreement is simpler but still important. It should cover:

A single-member operating agreement is typically 3–5 pages and can be created from a template.

Multi-Member LLCs

With two or more members, the operating agreement becomes significantly more important and more complex. Additional provisions should include:

Multi-member operating agreements typically run 10–20 pages and should ideally be reviewed by an attorney, especially for businesses with significant assets or complex ownership structures.

Key Provisions to Get Right

Capital Contributions and Ownership

Be explicit about what each member contributed and what they own. "We'll figure it out later" is how lawsuits start. Document initial contributions, any obligation for future contributions, and whether the LLC can make capital calls.

Profit Distribution vs. Tax Allocation

These are two different things. Tax allocation determines how profits and losses are reported for tax purposes (typically based on ownership percentage). Distributions are actual cash payments to members. Your operating agreement can allow distributions that don't match ownership percentages — for example, guaranteeing a managing member a minimum distribution for their labor.

Management Authority and Day-to-Day Decisions

Define what decisions a manager (or managing member) can make independently and which require a vote. Common thresholds include:

Exit and Buyout Provisions

This is arguably the most important section for multi-member LLCs, and it's the one most people skip because they're optimistic when starting a business. Address:

How to Create an Operating Agreement

Option 1: Use a Template (Free – $99)

For single-member LLCs and straightforward multi-member arrangements, a quality template is often sufficient. Entity Lane provides a state-specific operating agreement template as part of the formation process. Generic templates are also available from many legal websites, though state-specific versions are preferable.

Option 2: Use an Attorney ($500 – $2,000+)

For multi-member LLCs with significant capital, complex profit-sharing arrangements, or intellectual property considerations, hiring a business attorney to draft or review your operating agreement is money well spent. Look for an attorney experienced with LLCs in your state of formation.

Option 3: Legal Document Service ($100 – $500)

Services like LegalZoom and Rocket Lawyer offer customized operating agreements through guided questionnaires. These are more tailored than a generic template but less personalized than working directly with an attorney.

Common Mistakes to Avoid

  1. Not having one at all. This is the most common mistake. Even a basic template is better than nothing.
  2. Copying a generic template without customization. Your operating agreement should reflect your actual business arrangement, not a hypothetical one.
  3. Failing to sign it. An unsigned operating agreement is just a draft. Every member should sign and date it, and each member should keep a copy.
  4. Not updating it. If your LLC's ownership, management, or operations change, update the operating agreement. An outdated agreement can create confusion or legal problems.
  5. Including provisions that violate state law. While operating agreements have wide latitude, they can't override certain mandatory state law provisions (like the duty of loyalty in some states). This is another reason state-specific templates are better than generic ones.
  6. Oral agreements. Some states technically allow oral operating agreements, but they're nearly impossible to enforce. Put it in writing.

Frequently Asked Questions

Do I need to file my operating agreement with the state?

No. In all three Entity Lane states (NM, NC, GA) — and in most other states — the operating agreement is a private document. It is not filed with the Secretary of State. You keep it in your business records and provide copies to members, banks, and others as needed.

Can I write my own operating agreement?

Yes. There's no requirement that an attorney draft it. For single-member LLCs, a well-made template is usually sufficient. For multi-member LLCs with significant assets or complex arrangements, attorney review is recommended to avoid costly mistakes.

What if my LLC doesn't have an operating agreement?

Your LLC will be governed entirely by your state's default LLC Act rules. These defaults cover management, profit distribution, transfer of interests, and dissolution. They may not match your intentions — for example, all members may share equally in profits regardless of contribution, and any member may have authority to bind the LLC in contracts.

Can a single-member LLC have an operating agreement?

Yes, and it should. A single-member operating agreement serves as evidence that the LLC is a genuine separate entity, helps protect your limited liability, and satisfies bank requirements for opening a business account. It also documents successor procedures if something happens to you.

How often should I update my operating agreement?

Update your operating agreement whenever there's a material change: new members joining, members leaving, changes in ownership percentages, changes in management structure, or significant changes in how the business operates. At minimum, review it annually to ensure it still reflects your business reality.

Does an operating agreement need to be notarized?

No. Operating agreements do not need to be notarized in any state. They just need to be signed by all members. However, notarization doesn't hurt and can provide additional evidence of authenticity if the agreement is ever disputed.
