Do California Businesses Need an Operating Agreement?
October 17, 2026
When you start a business with partners, everyone may agree on the big picture. You have a shared vision, a plan for growth, and an understanding of what each person brings to the company. But what happens when one partner wants to sell, another wants to reinvest profits, or the owners disagree about a major business decision?
California LLCs are required to have an operating agreement, but the law does not generally require it to be written. A written agreement establishes the rules for ownership, management, financial decisions, and member responsibilities. It can also protect the business from costly disagreements as the company grows.
At Goyette, Ruano + Ulmer, our California business attorneys help entrepreneurs, founders, and established companies create operating agreements that reflect their ownership structure, business goals, and long-term plans.
What Is an LLC Operating Agreement?
An operating agreement is an internal document that governs how a limited liability company operates and how its members interact with one another.
Unlike the Articles of Organization, which are filed with the California Secretary of State, an operating agreement is maintained with the company's business records.
A well-drafted agreement typically addresses:
- Ownership interests: Each member's ownership percentage and contributions to the company.
- Management authority: Who makes decisions and whether the LLC is member-managed or manager-managed.
- Voting rights: Which decisions require majority approval, unanimous consent, or another threshold.
- Profit distributions: How and when company earnings are distributed to members.
- Ownership transfers: What happens when a member retires, dies, becomes disabled, or wants to sell.
- Dispute resolution: How members will address disagreements, deadlocks, or potential litigation.
These provisions become particularly important when a business takes on investors, expands its operations, or experiences changes in leadership.
Why Does Your California LLC Need a Written Operating Agreement?
California's Revised Uniform Limited Liability Company Act establishes default rules that apply when an operating agreement does not address a particular issue.
Those default rules may not reflect how you want your company to operate.
For example, two partners may contribute different amounts of capital but expect to share management responsibilities equally. Without carefully drafted provisions, disagreements about voting rights, distributions, or decision-making authority can create significant problems.
A written operating agreement allows owners to establish expectations that reflect their actual business relationship, within the limits of California law.
"Some of the most expensive business disputes begin with conversations the owners never had when things were going well. An operating agreement gives those conversations a place to happen before money, control, or the future of the company is on the line." - Founding Attorney Paul Goyette
Does a Single-Member LLC Need an Operating Agreement?
Yes. Even if you are the sole owner, a written operating agreement is a valuable part of establishing and maintaining your business.
It can document management authority, establish procedures for major decisions, and help demonstrate that the LLC operates as a separate legal entity.
However, an operating agreement alone does not guarantee personal liability protection. Business owners must also maintain appropriate records, follow applicable legal requirements, and keep business and personal finances separate.
When Should You Update an Existing Operating Agreement?
An operating agreement should evolve with the business. Owners should consider reviewing it when:
- New members or investors join the company.
- Ownership percentages or capital contributions change.
- Management responsibilities shift.
- The company prepares for financing, expansion, or a sale.
- A member plans to retire or exit.
- Disagreements expose gaps in the existing agreement.
For established LLCs in Sacramento and throughout Northern and Central California, an outdated agreement can be just as problematic as an incomplete one.
