Samuel Goldwyn quipped that a verbal contract isn’t worth the paper that it’s printed on. A signature remains the gold standard—even when the Statute of Frauds doesn’t require one. But who can sign? And what can happen when the person signing isn’t authorized to sign on their organization’s behalf?
Unauthorized signatures can lead to unenforceable agreements, personal liability, or internal disputes. This post breaks down Texas law on the subject, including default rules, apparent authority, and how companies can better manage the signature process.
1. Default Rules Under Texas Law
The first step is assessing authority. In Texas, corporations act through their officers and authorized agents. An LLC acts through its managers or members, depending on its structure (manager- vs. member-managed). These authorities are set out in the Texas Business Organizations Code (TBOC). The TBOC is flexible, allowing organizations to set out signature authority in their governing documents—certificates of formation, bylaws, company agreements, and board resolutions.
Texas courts are practical in their evaluation of authority. Courts look first to actual authority—express or implied. See Crooks v. M1 Real Estate Partners, Ltd., 238 S.W.3d 474, 483 (Tex. App.—Dallas 2007, pet. denied). Absent actual authority, Texas courts look to apparent authority—whether the company held the person out as having authority. When actual authority is unclear, Texas courts turn to the doctrine of apparent authority to protect reasonable third parties.
2. Apparent Authority and Real-World Risk
How does apparent authority play out in practice? If a company allows someone to appear as though they have authority—by title, email signature, or negotiation role—it may be bound even if that person lacked express authorization. Texas courts have long recognized apparent authority in cases like Gaines v. Kelly, 235 S.W.3d 179 (Tex. 2007). In Gaines, the Texas Supreme Court found that a mortgage broker who had blank loan forms and a letterhead did not have apparent authority to alter loan terms. In its holding, the court emphasized that apparent authority must be grounded in the principal’s conduct rather than unilateral statements by the agent.
Apparent authority creates real-world risks. After all, outside parties have little knowledge of the internal workings of companies, which are often opaque and confidential. A person purporting to represent the company—maybe with a company email address, business card, or polo shirt—is presumed to be an agent for the company. The specific titles and contract-specific authority levels vary widely by company. Without proper guardrails, it becomes extremely easy for outsiders to enter transactions with individuals who may lack proper authority.
3. How Companies Can Manage Signature Authority
Smart companies don’t leave signature authority delegation to chance. The first step is to have clear rules about who has what kind of signature authority. A baseline requirement is clear, written resolutions and delegations of authority specifying who can sign which types of contracts. Because Texas corporations act through their officers (and LLCs through their members or managers), these individuals must expressly delegate signing authority to avoid ambiguity.
To avoid these pitfalls, companies should formalize and document signature authority. Key steps include:
- Signature Blocks. Use signature blocks that clearly indicate title and capacity (“ABC LLC, by John Smith, Manager”). If a resolution clearly says that a person with that title is able to act, proving authority is straightforward.
- Clarify Dollar Amounts. Many companies classify signing authority by a transaction’s dollar amount. For example, any contract worth over $50,000 requires the CEO’s signature. This reduces ambiguity and helps manage financial risk.
- Streamline Questions. Train staff to route all signature questions through counsel or the corporate secretary. This precludes finger-pointing about authorization.
- Request Documentation. When in doubt, counterparties can request a certificate of incumbency, secretary’s certificate, or board resolution confirming authority.
4. Conclusion
Signature authority seems simple—but when overlooked, it becomes the first argument in a contract dispute. Whether you’re setting up internal controls or reviewing counterparties, confirm who can bind the company before you sign. In Texas, a signature isn’t just ink—it’s authority.
