How State Default Rules Govern Partner Authority

Under the Uniform Partnership Act (UPA) and the Revised Uniform Partnership Act (RUPA), every partner is an agent of the partnership for the purpose of its business. Consequently, any partner can legally bind the partnership to contracts in the ordinary course of business, even without a written agreement.

The Legal Foundation of Partner Agency

In the absence of a formal partnership agreement, state statutes serve as the default governing framework. These laws are designed to protect third parties who interact with a business, ensuring they can rely on the apparent authority of a partner.

Actual vs. Apparent Authority

  • Actual Authority: The specific power granted to a partner by the partnership agreement or a majority vote of the partners.
  • Apparent Authority: The power a partner appears to have to a third party based on their status as a partner and the nature of the partnership's business.

Key takeaway: Even if you have an internal rule prohibiting a partner from signing contracts over $10,000, that rule is unenforceable against a third party who is unaware of the restriction and reasonably believes the partner has the authority to sign.

Action Item: Audit your current partnership structure to determine if you are operating under default state statutes or a customized agreement. If you lack a written agreement, you are subject to the broadest possible interpretation of partner agency.

Statutory Frameworks by Jurisdiction

Most U.S. states have adopted some version of RUPA. While nuances exist, the core principle remains consistent: a partner's act for apparently carrying on in the ordinary course of the partnership business binds the partnership.

Jurisdiction FeatureImpact on Authority
Statement of AuthorityAllows a partnership to file a public document limiting or granting authority.
Ordinary Course of BusinessThe threshold for whether a partner's signature is binding.
Notice to Third PartiesRequired to invalidate a partner's apparent authority.

The Role of the Statement of Authority

Many states allow partnerships to file a "Statement of Authority" with the Secretary of State. This document is a powerful tool because it provides constructive notice to the world regarding who has the power to bind the entity. Once filed, third parties are deemed to have knowledge of the limitations contained therein.

Action Item: Check your Secretary of State’s business portal to see if a Statement of Authority has been filed for your entity. If not, consider filing one to protect the partnership from rogue partner actions.

Mitigating Unauthorized Binding Risks

To prevent a partner from unilaterally binding the business, you must move beyond default state rules. Relying on verbal understandings is a recipe for litigation.

  1. Draft a Comprehensive Partnership Agreement: Explicitly define the scope of authority for each partner.
  2. Implement Internal Controls: Require dual signatures for all contracts exceeding a specific dollar threshold (e.g., $5,000).
  3. Provide Explicit Notice: If a partner is restricted, notify your primary vendors, banks, and service providers in writing.
  4. Use Corporate Resolutions: For major transactions, require a formal board or partner vote documented in the minutes.

Key takeaway: A contract signed by a partner acting within the 'ordinary course of business' is binding on the partnership, even if the partner violated internal policies. The partnership may have a claim against the partner for breach of duty, but the contract with the third party remains valid.

Action Item: Review your existing contracts to identify 'Authority' or 'Signatory' clauses. Ensure these clauses align with your internal governance policies.
