Do I Need an LLC Operating Agreement?

By Sarah Chen, JD · May 26, 2026 · 12 min read

The Short Answer: Absolutely Yes

An LLC operating agreement is not merely a formality—it is the single most critical legal document your business possesses. Whether you have one member or twenty, a formal operating agreement protects your personal assets, governs internal dispute resolution, and satisfies the compliance requirements of major financial institutions. Skipping it is a risk no prudent founder should take.

What Is an LLC Operating Agreement?

An LLC operating agreement is a legally binding contract executed by all members of a Limited Liability Company. It establishes the internal governance framework of the business, including:

• Ownership percentages (membership interests) for each member
• Profit and loss distribution methodology
• Voting rights and decision-making thresholds
• Management structure (member-managed vs. manager-managed)
• Capital contribution requirements and schedules
• Procedures for admitting new members or handling member exits
• Dissolution procedures and winding-up protocols
• Fiduciary duties and indemnification provisions

Why Your Personal Assets Are at Risk Without One

The primary reason founders form an LLC is to create a legal barrier between their personal finances and business liabilities. This shield is called the "corporate veil." However, this veil is not automatic—it must be actively maintained through proper corporate formalities, and the operating agreement is the foundational document that establishes those formalities.

Without an operating agreement, courts examining a dispute may find insufficient evidence that your LLC operates as a genuine, separate legal entity from you personally. This allows creditors to pursue what is known as "piercing the corporate veil"—bypassing the LLC entirely and seizing your personal assets including your home, vehicle, savings, and investments.

State Default Laws: A Hidden Danger

Every state with LLC statutes has a default set of rules that apply automatically when no operating agreement exists. These defaults are rarely favorable to business owners:

• Equal profit splits: In many states, default law requires that profits be distributed equally among members, regardless of how much each person contributed. If you invested $90,000 and your partner $10,000, you may be legally entitled to only 50% of profits.
• Unanimous voting requirements: Some state defaults require unanimous member consent for all business decisions, making day-to-day operations nearly impossible in multi-member LLCs.
• Automatic dissolution: Many states automatically dissolve an LLC if any member leaves, dies, or goes bankrupt—unless the operating agreement specifies otherwise.

Banking Requirements

Federal Anti-Money Laundering (AML) and Know Your Customer (KYC) regulations require banks to verify the legitimacy of business entities. Virtually every reputable financial institution—including Chase Business, Bank of America Business, Mercury, Brex, and Silicon Valley Bank—requires a signed operating agreement before opening a business checking account, issuing a business credit card, or extending a line of credit.

Without a proper operating agreement, you may be unable to open a business bank account, which means you'll be forced to use personal accounts for business—the exact behavior that destroys your liability protection.

States That Legally Require an Operating Agreement

While most states strongly recommend an operating agreement, some have enacted laws making it legally mandatory:

• California: All LLCs must have a written operating agreement (California Corporations Code § 17701.10)
• New York: Requires a written operating agreement within 90 days of formation (NY LLC Law § 417)
• Delaware: Highly encourages written agreements for maximum contractual flexibility
• Maine: Requires a written operating agreement
• Missouri: Requires members to adopt a written operating agreement
