Authorized signatory: who can sign for a company

A company cannot hold a pen. Every contract it signs is signed by a person, and the question that decides whether the company is bound is simple: did that person have the authority to sign?

Authorized signatory

A person who is legally entitled to sign documents, such as contracts, bank instructions, tax returns or invoices, on behalf of an organisation or another person. Also called an authorised signatory (British and Indian spelling), authorized signer or signing officer.

Signing authority

The power itself: what a person may sign, up to which value, alone or jointly with someone else. Also called signatory authority or signature authority. A company’s rules for who holds it are usually written down in a delegation of authority policy or a signing authority matrix.

“Authorized signatory” describes the person’s power to bind. “Signatory” on its own just means someone who signs. For the difference between signatory, signer, signee, party and witness, see our guide to contract signatory roles.

Who has signing authority in a company?

Authority to sign comes from a small number of sources. The higher up this list, the broader the authority usually is, and the easier it is for an outsider to check.

A few jurisdiction notes that come up often:

• United States. Officers’ titles and duties come from the bylaws or a board resolution (in Delaware, DGCL § 142). A CEO or president is generally treated as able to sign ordinary-course contracts. Unusual or very large transactions (selling the business, major loans, real estate) usually need board approval.
• United Kingdom. Under the Companies Act 2006, s. 44, a company can execute a document by the signature of two authorised signatories (two directors, or a director and the company secretary) or by one director in the presence of a witness who attests the signature. Under s. 40, a person dealing with the company in good faith can generally rely on the directors’ power to bind it, even if the constitution limits that power.
• Germany. A GmbH is represented by its managing directors (§ 35 GmbHG). If there are several, they represent jointly unless the articles say otherwise, and the Handelsregister shows which rule applies. Internal limits on a managing director’s authority have no effect against third parties (§ 37(2) GmbHG). A Prokurist can sign almost anything the business entails, but cannot sell or encumber land without special authority (§ 49 HGB), and signs with “ppa.” (see p.p., ppa. and other signing abbreviations).
• India. “Authorised signatory” is also a defined role in tax filings. For GST registration, a business names its authorised signatories and uploads a letter of authorisation or a board resolution, together with the signatory’s acceptance letter, as proof of appointment.

Actual authority vs apparent authority

The law distinguishes two kinds of authority, and the difference decides most disputes.

• Actual authority is authority the company really gave. It can be express (a board resolution says “the CFO may sign loan agreements up to $1 million”) or implied (a purchasing manager is implicitly authorised to sign routine purchase orders, because that is the job).
• Apparent authority exists when a third party reasonably believes a person has authority, and that belief is traceable to something the company did or allowed: a job title, a business card, a history of letting that person sign similar contracts. The Restatement (Third) of Agency (§ 2.03) defines it this way for US law, and English law reaches similar results through the doctrine of ostensible authority.

Apparent authority protects counterparties. It is also why an internal limit (“managers may sign up to $50,000”) does not reliably protect the company if nobody outside knows about it.

4 types of signing authority

Inside a company, signing authority is usually granted at one of four levels.

1. Full authority. The person can sign any document for the company, usually a CEO or managing director with sole representation.
2. Limited authority. Restricted to certain document types or values, for example a department head who can sign purchase orders and supplier contracts up to $25,000, but not leases or loans.
3. Joint authority. Two signatures are needed for the document to be valid, such as CEO and CFO for a loan agreement, or “any two directors” on a bank mandate. This is the classic four-eyes principle.
4. Conditional authority. The person can sign only after a defined approval, for example a buyer who may sign once finance has approved the budget.

Signing authority matrix: an example

A signing authority matrix (also called a delegation of authority matrix or DoA matrix) puts the rules on one page: which contracts, up to which value, who signs, who must approve first. A simplified example for a mid-sized company:

The thresholds are illustrative. Yours should follow your risk appetite and, where they apply, your bylaws and statutory rules on joint representation.

How to grant signing authority

Step 1: Map who needs to sign what

List the agreements your company signs regularly (NDAs, sales contracts, supplier agreements, employment contracts, leases) and who currently signs them. The gaps show up quickly: contracts nobody is formally allowed to sign, and people signing far above their level.

Step 2: Set authority levels

Turn that list into a matrix like the one above. Decide where a single signature is enough, where two are needed, and which approvals must come before signing. Keep the number of signatories practical: at least two people per category, so a contract does not stall when one of them is on holiday.

Step 3: Put it in writing

Authority that only exists in people’s heads cannot be proven. Depending on who is being authorised, use one of these:

• Board resolution. The standard way for the board to authorise an officer or a named person, either generally or for a specific transaction. Boards and shareholders can often pass these in writing without a meeting, as a circular resolution.
• Delegation of authority policy. The internal rulebook: the matrix plus the process for changing it.
• Power of attorney or letter of authorisation. For a named individual, including external agents. It should state the scope, the value limits and the period of validity. See how to sign as power of attorney.
• Commercial register entry. For managing directors and Prokuristen in Germany, the authority only becomes visible to third parties once it is registered.

A sample board resolution clause:

RESOLVED, that Jane Smith, Chief Financial Officer, is authorized to negotiate, sign and deliver on behalf of the Company any supplier agreement with a total value of up to USD 250,000, and that this authority remains in force until revoked by resolution of the Board.

Step 4: Monitor and update

Review the matrix at least once a year and whenever someone with authority changes roles or leaves. Revoke authority in writing, tell the banks and key counterparties, and update the commercial register where the authority is registered. Spot-check signed contracts against the matrix to catch signatures outside the limits.

How to verify that someone can sign

Before you rely on a counterparty’s signature for a significant contract, check their authority. The usual documents:

For a German GmbH, the register extract answers most questions in a minute: it lists each Geschäftsführer and Prokurist and states whether they may represent the company alone or only together with another. If the extract says “jointly with another managing director or a Prokurist” and only one person signed, the contract is not properly signed for the company.

What happens if someone signs without authority?

The contract does not automatically bind the company, but it does not simply disappear either. Four outcomes are possible:

1. The company is bound anyway, through apparent authority. If the company created the impression that the person could sign and the counterparty reasonably relied on it, the company is bound.
2. The company ratifies the contract. A company can approve an unauthorised contract after the fact, expressly or by conduct (for example by accepting the goods or paying the invoice). Ratification makes it binding as if it had been authorised from the start.
3. The company is not bound, and the signer is personally liable. A person who signs claiming authority they do not have can be liable to the counterparty for breach of the implied warranty of authority (Restatement (Third) of Agency § 6.10 in the US; in English law since Collen v Wright (1857)). In Germany, a contract signed by an agent without authority is pending until the principal approves or refuses it (§ 177 BGB). If the principal refuses, the agent is liable to the other party for performance or damages, at the other party’s choice (§ 179 BGB).
4. Internal consequences. Even where the company ends up bound, an employee who signed outside their limits can face disciplinary action or a damages claim from the employer.

The practical lesson runs both ways. As a counterparty, verify authority on anything that matters. As a company, keep your matrix current and make sure the people you do not want signing contracts are not given job titles, templates or a track record that suggest they can.

Sample authorized signatory signature block

The signature block should make clear that the person signs for the company, not for themselves. A standard US-style block:

ACME Inc.

By: ______________________________
Name: Jane Smith
Title: Chief Financial Officer
Date: ____________________________

Where two signatures are required, give each signatory their own “By / Name / Title” lines under the company name. On invoices, letters and tax documents, particularly in India and the UK, the common form is “For ACME Pvt Ltd” above the signature line and “Authorised Signatory” below it.

Signing your own name without the company name and your capacity is the most common mistake, because it can make the signature read as personal. For signing on behalf of an individual rather than a company (p.p., “for and on behalf of”, attorney-in-fact), see how to sign on behalf of others.

Enforcing signing authority in your contract workflow

A matrix in a spreadsheet does not stop anyone from signing. The rules hold when they are built into the process the contract has to pass through. In contract management software like fynk, approval workflows block a contract from moving to signing until every required approval is in, and the signing order routes it to each authorized signatory in turn. Every signature is logged with a timestamp, the signer’s identity and the method, so you can show later who signed and when.

Frequently asked questions

• What is an authorized signatory?

  An authorized signatory is a person with the legal power to sign documents on behalf of a company or another person, so that the signature binds the company rather than the signer. The authority comes from the law, the company's bylaws, a board resolution, a delegation policy or a power of attorney.

• What does authorized signatory mean on an invoice or letter?

  It shows that the person signing does so for the company, not personally. The usual form is the company name above the signature (For ACME Pvt Ltd) and the words Authorised Signatory below it.

• Who can be an authorized signatory of a company?

  Directors and managing directors usually have authority by law. Officers such as the CEO or CFO get it from the bylaws or a board resolution. Any other employee or an outside agent can be authorised through a board resolution, a delegation of authority policy or a power of attorney.

• Can anyone be a signatory?

  Anyone with legal capacity can sign a contract for themselves. Signing for a company is different: the signature only binds the company if the person has authority to sign for it, or the company created the reasonable impression that they do.

• How do I prove I am an authorized signatory?

  Show the document that gives you authority: a board resolution or secretary's certificate, an incumbency certificate, a power of attorney, or, for directors and Prokuristen in Germany, the commercial register extract. Banks and large counterparties will usually ask for one of these.

• Is the CEO automatically an authorized signatory?

  In most companies the CEO can sign ordinary business contracts, either under the bylaws or because the role carries that authority. Unusual or very large transactions, such as selling the business, major loans or real estate deals, often still need board approval.

• What is a signing authority matrix?

  A table that sets out who may sign which types of contracts, up to which value, and which approvals are needed first. It is the practical core of a delegation of authority policy.

• How many authorized signatories should a company have?

  Enough that contracts do not stall when someone is away, usually at least two per contract category. Large or risky contracts often need two signatures together, which also gives you a four-eyes check.

• What happens if an unauthorized person signs a contract?

  The company is usually not bound, unless it ratifies the contract or created the impression that the person had authority. If the company is not bound, the person who signed can be personally liable to the other party.
