Walford v Miles [1992] 2 AC 128
Facts
The Miles family negotiated with the Walfords for the sale of a business and premises. The contemplated sale remained subject to contract. During the discussions, the sellers gave assurances that they would not negotiate with other interested purchasers, but no fixed exclusivity period was agreed. They later chose to sell to another buyer. The Walfords claimed that withdrawing and negotiating elsewhere breached an enforceable undertaking. The House of Lords had to distinguish a promise not to deal with third parties from a positive obligation to continue negotiations in good faith.
Legal Issue
Was the open-ended negotiating arrangement enforceable, and how does a bare duty to negotiate in good faith differ from a supported lockout agreement for a specified period?
Held
The House of Lords rejected enforcement of the arrangement alleged. A bare agreement to negotiate in good faith lacked sufficiently certain content in this setting. The court could not determine a workable obligation to continue until a proper reason for withdrawal arose while the parties were still pursuing their separate commercial interests. The House distinguished a negative lockout promise: for good consideration, a seller can agree not to negotiate with others for a specified period. Such a promise has an ascertainable duration and does not necessarily require agreement with the favoured bidder. Here the absence of a defined period was fatal to the claimed lockout. The decision did not authorise misrepresentation or breach of a separately enforceable obligation during negotiations.
⭐ Legal Principle
A bare open-ended agreement to negotiate in good faith was unenforceable in Walford. A lockout agreement supported by consideration and lasting for a specified period can be enforceable, because excluding third-party negotiations differs from requiring the parties to negotiate to agreement.
Significance
Walford is central to contractual certainty and preliminary commercial arrangements. It shows why drafting a defined exclusivity obligation is different from relying on a general assurance that negotiations will continue fairly. Its reasoning should not be used to invalidate every term containing good faith. Duties in an existing contract, or more specifically defined mechanisms, require their own analysis. Compare Yam Seng on performance obligations: the legal setting and content of the undertaking matter more than the presence of the same phrase.
Common exam questions about this case
What is the difference between a lockout and a lock-in?
A lockout prevents dealings with third parties for the agreed period. It need not compel the seller to reach terms with the protected bidder. A lock-in would positively require continuing negotiations. Walford rejected the bare open-ended good-faith obligation alleged, while recognising that a properly defined and supported lockout can be enforceable.
Why did a specified period matter?
It gives the negative promise an ascertainable duration. Without an agreed period, the court would have to supply limits closely connected to the uncertain duty to continue negotiations. A fixed exclusivity period allows the parties and court to identify what conduct is prohibited and when that restriction ends.
Does Walford make Yam Seng’s discussion of good faith impossible?
No. Walford concerns preliminary negotiations and the uncertain obligation pleaded there. Yam Seng concerns the content of duties in a concluded distribution agreement. Both require attention to context and defined obligations. The words good faith alone do not determine enforceability across every stage and type of commercial relationship.
