The Business Card Is Not a Warrant: When an Employee’s Assent Binds the Company

A familiar sequence, an uncomfortable question

A supplier’s account manager receives an email from a sales manager at a long-standing customer. The message confirms a twelve-month extension, a revised discount and a new delivery schedule. It is written on company paper, carries a job title and ends with a confident ‘thanks for sorting this’. No director has seen it. Three months later, the customer denies the discount and says the sales manager had no authority. The supplier asks whether the email is worth the screen it is written on. In UK contract law, the answer may be that the company is bound — not because the sales manager had permission, but because the company allowed the outside world to believe that she did.

Actual authority and apparent authority are not the same

An employee may bind a company in two broad ways. The first is actual authority: express permission in a contract, job description, board resolution or delegated authority schedule, or implied permission arising from the role and the usual practices of the business. A finance director who routinely signs supply contracts up to a stated value has actual authority to do so, even if no single document says so in terms.

The second is apparent authority, sometimes called ostensible authority. It arises where the company makes a representation that a person has authority to act on its behalf, and a third party reasonably relies on that representation. The classic statement is in Freeman & Lockyer v Buckhurst Park Properties (Mangal) Ltd [1964] 2 QB 480. The representation need not be a formal letter. It may come from appointing someone to a role, allowing them to use a title, providing them with company email and letterhead, or permitting them to conduct negotiations over a period. The company is then treated as having held that person out as its agent.

The distinction matters because apparent authority can exist despite an internal ‘no’. A company cannot rely on a private restriction if it has created the appearance of authority and the third party has no notice of the restriction.

The representation must come from the company

Apparent authority is not a licence for an employee to manufacture their own power. A person cannot create apparent authority simply by claiming it. In Armagas Ltd v Mundogas SA [1986] AC 717, the House of Lords emphasised that the representation must be made by the principal, or by someone with actual authority to make it. A rogue employee who invents a title, forges a letter or assures a supplier that ‘the board has approved it’ does not, without more, bind the company.

That is why context is everything. A sales manager who has negotiated with the same supplier for years, copied into board correspondence and permitted to issue purchase orders may have apparent authority to agree ordinary commercial terms. The same sales manager may have no apparent authority to grant a five-year exclusivity, accept liability for consequential loss or vary the payment terms in a way that no one in the company has ever done.

What the third party has to show

A supplier or customer seeking to rely on apparent authority will usually need to show three things. First, that the company made a representation of authority. Second, that the third party relied on it. Third, that reliance was reasonable and led to a change of position — for example, committing to stock, performing services or forgoing another opportunity.

Reasonableness is not a rubber stamp. If the third party knew of an approval threshold, saw a ‘subject to board approval’ caveat, dealt with a junior employee outside their obvious remit, or was told to await a director’s signature, reliance is unlikely to be reasonable. A party that suspects something is wrong and deliberately avoids asking questions cannot later claim to have been reassured.

The warning signs worth noticing

Most disputes about authority are visible before the contract is signed. The value is far above the employee’s grade. The terms are unusual for the industry or for that customer. The employee is hurried, evasive or asks for the matter to be kept from the finance team. The correspondence moves to a personal email address. The signature block is inconsistent with the company’s usual documents. Payment is requested to a new account. No purchase order is raised.

None of these facts automatically means the contract is void. They are prompts to check. A request for written confirmation from a director or company secretary is not an insult; it is ordinary commercial hygiene.

Ratification can turn a rogue yes into a binding contract

Even if an employee had no authority at the time, the company may later ratify the contract. Ratification can be express — a board resolution confirming the deal — or implied by conduct. If the company accepts the benefit of the contract, pays an invoice, takes delivery or continues to perform without reservation, a court may infer that it has adopted the transaction.

That creates a practical trap. A business that discovers an unauthorised commitment should not simply carry on and argue later. It should take advice quickly, preserve the correspondence and, if it intends to challenge the contract, avoid conduct that looks like acceptance. Silence alone is not always ratification, but silence combined with performance often is.

Authority checks that fit a small business

SMEs do not need a legal department to reduce this risk. They need clear boundaries and a habit of verification.

First, maintain a delegated authority matrix. Set financial thresholds for roles and make sure staff, customers and suppliers know who can sign what. Second, adopt a contract execution policy: only named directors or authorised signatories may bind the company, and material variations require written approval. Third, include standard wording in terms and conditions and purchase orders stating that no employee has authority to vary the contract unless the variation is signed by a director.

Fourth, verify. If an employee confirms a significant deal, ask for confirmation from a director or the company secretary. Check the company’s website, Companies House record and previous correspondence for consistency. Fifth, control the trappings of authority: job titles, email signatures and business cards should not suggest powers that do not exist. Sixth, train sales and administrative staff to escalate unusual requests rather than improvise.

The point of the exercise

Apparent authority protects the reasonable outsider who relies on the company’s own presentation of its staff. It is not a trap for the unwary business; it is a consequence of holding someone out as able to act. For SMEs, the lesson is neither to assume that every employee’s yes binds the company nor to assume that a private approval rule protects it. The safer course is to make authority visible, verify it when the stakes justify it, and act quickly if an unauthorised yes has already escaped.
