Letter Of Authority To Sign On Behalf Of Company Template for the United States

When your company needs to delegate signing authority to a specific person, you'll use a Letter Of Authority To Sign On Behalf Of Company. This formal document legally empowers a designated individual to execute contracts, agreements, and other binding documents for the company. Under United States law, that authority must be properly documented so both your business and the third parties who rely on the signatory are protected.

What does authority to sign on behalf of a company mean?

Authority to sign on behalf of a company is the legal right of a named person to bind the business to an agreement by adding their signature. That right usually comes from actual authority, granted in writing through this letter, a board resolution, or a company's operating agreement or bylaws. It can also arise from apparent authority, where the company's conduct leads a counterparty to reasonably believe someone can sign, even without a formal grant. There is also implied authority, where a person's role or position carries the reasonable power to enter contracts needed to do that job, even when nothing is written down. A clear letter of authority removes the guesswork by putting the actual authority in writing, so nobody has to rely on apparent or implied authority when a signature matters.

Types of authority to sign

Each can bind the company, so putting actual authority in writing is the safer route for the business and its counterparties.

When do you need this document?

You'll want this letter whenever your primary signatories are unavailable for extended periods, such as during travel or illness. It's also useful when you expand operations across multiple locations and local managers need signing power for day-to-day transactions. Many companies use these letters to authorize department heads to sign contracts within their remit, such as procurement or service agreements. Banks and financial institutions often ask for this documentation before letting non-officer employees conduct business for the company. You'll also reach for it when establishing relationships with new vendors or clients who want proof that your representative can bind the company.

How do you grant signing authority correctly?

Start with the scope of authority, the most important part of the letter, because it defines exactly what actions the authorized person can take. Specify whether the authority covers all business transactions or is limited to certain agreements, dollar amounts, or functions, and add clear limitations to prevent actions that could bind the company beyond your intent. The duration clause should give exact start and end dates, since open-ended grants create ongoing liability. Identify the authorizing party in full, usually with signatures from corporate officers, a director, or board members as set out in your articles of incorporation or operating agreement. In practice, a revocation clause is worth including so the authority can be ended cleanly and relevant parties are told once it lapses. Store a signed copy where the signatory and any counterparty can find it, and update it whenever roles change. It's good practice to review the letter each time the signatory's role or the company's structure changes, so the necessary authority stays current.

What details should the letter contain?

A complete letter of authority (sometimes called a signing authority letter) generally includes:

• The company's full legal name as registered with the Secretary of State, and its registration number where required.
• The name and title of the person being granted authority.
• The scope of authority, including any transaction types, dollar limits, or functions covered.
• Any express limitations or restrictions on what the person may sign.
• The start and end dates, or the conditions under which the authority ends.
• A contact for the authorizing officer, so a counterparty can verify the grant.
• The signature of the authorizing officer, director, or board member, dated.

If your business is an LLC, check your operating agreement first, since it often names who can grant this authority and who is a company signatory, and may set out the procedure a signing authority template should follow.

Legal requirements in the United States

Your Letter Of Authority must line up with your state's corporation or LLC statutes and your company's own governing documents. Most states expect the person granting authority to hold that power under the articles of incorporation, bylaws, or operating agreement. The E-SIGN Act permits electronic signatures in many commercial contexts, though notarization may still apply to certain high-value transactions or real estate matters. State agency law governs the principal-agent relationship the letter creates, setting the party authority, fiduciary duties, and potential liability for both sides. Reference your company's registered legal name and, where relevant, include specific language about the agent's authority and its limits, so the letter meets your jurisdiction's formatting and content standards. If you need to delegate signing power through a board vote instead, a corporate resolution granting signing authority can sit alongside this letter.
