How State Statutes Govern Unauthorized Partner Contracts

When no written agreement exists, state statutes—primarily based on the Uniform Partnership Act (UPA) or Revised Uniform Partnership Act (RUPA)—default to the principle of apparent authority. This means the partnership is legally bound by any contract signed by a partner acting in the ordinary course of business, regardless of internal authorization.

The Doctrine of Apparent Authority

In the absence of a written partnership agreement, courts look to the statutory default rules. Under RUPA Section 301, every partner is an agent of the partnership. If a partner enters into a contract that appears to be for the carrying on of the partnership's business in the ordinary course, the partnership is bound.

Key Criteria for Enforceability

  • Ordinary Course of Business: Does the contract relate to the partnership's typical operations?
  • Third-Party Knowledge: Did the third party know or have reason to know that the partner lacked authority?
  • Scope of Business: Does the contract fall within the general scope of the partnership's industry or trade?

Key takeaway: If a third party has no reason to suspect a partner lacks authority, the partnership is almost always liable for the contract, even if the partner acted in direct violation of internal partnership rules.

Action Item: Review your state's specific version of the RUPA to determine if your partnership qualifies as a general partnership, which triggers these default agency rules.

Liability and Fiduciary Duties

When a partner signs an unauthorized contract, the partnership remains liable to the third party. However, the partnership may have recourse against the rogue partner. Because partners owe fiduciary duties of loyalty and care to one another, an unauthorized act that harms the partnership can be grounds for a lawsuit.

Action TypePartnership LiabilityRecourse Against Partner
Ordinary BusinessFully LiablePossible (if breach of duty)
Extraordinary BusinessPotentially LiableHigh (breach of authority)
Fraudulent/IllegalLimited (if 3rd party knew)High (legal/criminal)

Proving Breach of Duty

To hold a partner accountable for an unauthorized contract, you must demonstrate:

  1. The partner acted outside the scope of the partnership's ordinary business.
  2. The partner failed to disclose the contract to other partners.
  3. The contract resulted in measurable financial loss to the partnership.

Action Item: Document all internal communications regarding decision-making authority to establish a clear record of what constitutes 'authorized' behavior.

Mitigating Risks Without a Written Agreement

Since you lack a written agreement, you are operating under the 'default' statutory framework. This is inherently risky because it provides no mechanism to restrict a partner's power to bind the firm. You must take proactive steps to limit exposure.

  • Public Filings: In some jurisdictions, you can file a 'Statement of Partnership Authority' with the Secretary of State to limit the types of contracts specific partners can sign.
  • Third-Party Notification: If you know a partner is acting erratically, notify key vendors and clients in writing that the partner no longer has authority to bind the firm.
  • Internal Resolution: Pass a formal resolution (even if not a full agreement) signed by all partners defining the limits of authority.

Key takeaway: A Statement of Partnership Authority is the most powerful tool to override default statutory agency rules, as it provides constructive notice to third parties regarding who can bind the partnership.

Action Item: Consult with a business attorney to file a Statement of Partnership Authority immediately if you suspect a partner is exceeding their bounds.
