How State Law Determines LLC Member Authority Without an Operating Agreement

Without an operating agreement, state default statutes govern LLC member authority. In most jurisdictions, every member of a member-managed LLC possesses the statutory agency power to bind the company to contracts in the ordinary course of business, regardless of their ownership percentage.

The Default Rule: Statutory Agency

When an LLC is formed without an operating agreement, it defaults to the "statutory default" rules provided by the state in which it was organized. Most states follow the Revised Uniform Limited Liability Company Act (RULLCA) or similar frameworks. Under these rules, the management structure is the primary determinant of authority.

Member-Managed vs. Manager-Managed

The distinction between these two structures is the most critical factor in determining who can sign contracts on behalf of the entity.

  • Member-Managed: Every member is an agent of the LLC. Any member can sign contracts, open bank accounts, and incur debt that binds the company.
  • Manager-Managed: Only the appointed managers have the authority to act for the company. Members are essentially passive investors and lack the legal authority to bind the LLC.

Key takeaway: If you did not file specific paperwork designating your LLC as "manager-managed" at the time of formation, your state likely treats it as "member-managed" by default, granting every member full binding authority.

Action Item: Check your original Articles of Organization filed with the Secretary of State. If you did not explicitly check the box for "Manager-Managed," assume all members have full authority.

The Scope of "Ordinary Course of Business"

State laws generally limit a member's binding authority to the "ordinary course of business." This is a legal standard that distinguishes between routine operations and extraordinary transactions.

Transaction TypeBinding Authority
Routine supply contractsYes
Hiring/Firing employeesYes
Selling all company assetsNo
Taking out major loansOften No
Amending Articles of OrgNo

If a member enters a contract outside the ordinary course of business, the LLC may argue the member lacked "apparent authority." However, third parties are often protected if they reasonably believed the member had the power to act.

Risks of Operating Without an Agreement

Operating without a written agreement creates significant exposure. Because state laws are designed to be broad to protect third-party creditors, they rarely protect the LLC from the rogue actions of a single member.

  • Unilateral Debt: A member could sign a high-interest loan that the company is legally obligated to repay.
  • Contractual Liability: A member could sign a multi-year lease or service agreement that the other members oppose.
  • Lack of Internal Recourse: Without an operating agreement, you lack a clear "breach of contract" mechanism to sue a member for exceeding their authority.

Key takeaway: Relying on state default law is a gamble. Statutes are written to facilitate commerce, not to protect internal LLC disputes. If a member binds the company, the company is usually stuck with the contract, even if the other members are furious.

Action Item: If you have multiple members, draft a simple "Statement of Authority" and file it with your Secretary of State to publicly restrict which members can sign for the company.

How to Mitigate Authority Risks

If you cannot immediately draft a comprehensive operating agreement, you must take proactive steps to limit exposure.

  1. File a Statement of Authority: Many states allow you to file a specific document that lists which members have the power to bind the company. This provides constructive notice to third parties.
  2. Notify Vendors: Send formal letters to your bank, primary suppliers, and landlords stating that only specific individuals are authorized to sign contracts.
  3. Internal Resolution: Pass a simple written resolution signed by all members that explicitly restricts the authority of specific individuals. While this may not stop a third party from enforcing a contract, it creates a legal basis for the LLC to seek damages from the rogue member.

Conclusion

State default laws are a safety net for the public, not a shield for LLC members. By failing to define authority in an operating agreement, you grant every member the power to commit the company to significant financial obligations. Understanding your state's specific statutes is the first step in protecting your business assets.
