Operating Agreement vs Articles of OrganizationWhat each document does, what it contains, and how the two work together

The Articles of Organization create the LLC; the Operating Agreement governs it. Two documents, two purposes, two audiences. Articles are filed with the state, are public, and are short. Operating agreements are private, are held in the LLC's records, and are detailed. Confusing the two is one of the most common LLC formation mistakes. This page sets out exactly what each document does, what each typically contains, and how they work together to form and govern an LLC.

Different states use different terminology. California, Florida, and most states call the formation document "Articles of Organization". Delaware, Texas, and a few others call it "Certificate of Formation". The two terms are functionally identical: the document filed with the state to create the LLC.

What Goes in the Operating Agreement

Operating agreements are detailed governance documents. A standard multi-member operating agreement covers member identification and capital contributions, profit and loss allocation, distribution policy, voting rights and thresholds, management authority and decision-making, admission of new members, transfer restrictions and rights of first refusal, mandatory buyout triggers (death, disability, divorce, bankruptcy), valuation methodology for buyouts, manager and officer authority (in manager-managed LLCs), fiduciary duties, indemnification, dispute resolution, books and records, tax allocation and distributions, dissolution and winding up, and amendment procedures.

A typical multi-member operating agreement runs 25 to 50 pages. Single-member operating agreements are shorter (10 to 20 pages) because there is no inter-member governance. Operating agreements for venture-backed, private equity, or family-office LLCs can run 75 to 150 pages with extensive customisation.

The Operating Agreement covers everything the Articles do not. The Articles say "this LLC exists and is member-managed". The Operating Agreement says "the members are A, B, and C with these capital contributions and these voting rights, distributions occur quarterly per this schedule, transfers require ROFR, and disputes are resolved by mediation followed by AAA arbitration in Delaware". The Articles are the foundation; the Operating Agreement is the building.

D.

How the Two Documents Interact

The Articles take precedence on the narrow set of items they address. If the Articles state member-managed structure, the Operating Agreement cannot create a manager-managed structure (Articles must be amended first). If the Articles list a specific registered agent, the Operating Agreement's reference to a different agent is ineffective until the Articles are amended.

The Operating Agreement governs everything not in the Articles. Member percentages, capital contributions, voting thresholds, distribution policy, transfer restrictions, dispute resolution: none of these belong in the Articles, and all of them belong in the Operating Agreement. State default rules fill any gap in the Operating Agreement; the Operating Agreement controls over state defaults wherever the agreement addresses a topic.

When changing a fundamental element, the right document determines the right process. Changing the LLC name requires an Amendment to the Articles (filed with the state, typical fee $20 to $100). Changing the profit-allocation formula requires an amendment to the Operating Agreement only (no state filing, just signed amendment). Changing from member-managed to manager-managed requires both: amend the Articles (state filing) and amend the Operating Agreement (internal).

Five Common Confusions

Filing the Operating Agreement with the state

Many founders mail their Operating Agreement to the Secretary of State. The Secretary returns it; Operating Agreements are not filed.

Skipping the Operating Agreement because the Articles exist

The Articles legally form the LLC but do not govern operations. Without an Operating Agreement, default state rules govern, which rarely match what members actually want.

Putting member percentages in the Articles

Most states do not require member names or percentages in the Articles, and including them makes the information public. Member details belong in the (private) Operating Agreement.

Changing the Operating Agreement to alter management structure

If the Articles state member-managed, amending the Operating Agreement is not enough. File an Amendment to the Articles first, then amend the Operating Agreement.

Treating the Articles as the operating document

Banks, lenders, and courts ask for both. The Articles prove the LLC exists; the Operating Agreement proves how it operates and who has authority.
