Gentleman’s agreement – definition and meaning

A gentleman’s agreement is an informal, non-binding agreement in which the parties trust one another to keep their promises. We can also use the plural, and say ‘gentlemen’s agreement.’ It is not usually a document, i.e., there are no signatures, papers, or writing. If one of the parties breaks the agreement, the others do not usually have recourse to the courts. Put simply, a gentleman’s agreement has no legal force in most places.

However, in the United Kingdom, this type of agreement may be legally binding (see the last section of this article).

Each party in a gentleman’s agreement has faith that everybody will fulfill their promise because of their sense of personal honor.

According to

“A gentleman’s agreement or a gentlemen’s agreement is an informal agreement in which people trust one another to do what they have promised.”

All dictionaries online say that the phrase never refers to a written agreement. However, Wikipedia says “It is typically oral, though it may be written.”

Sometimes, if the parties know each other extremely well, it may even be a non-verbal agreement.

Gentleman’s agreement – legally binding?

In 2016, after carefully examining evidence, the British High Court accepted that a gentleman’s agreement could be legally binding.

The High Court ruled that even if not written down as a formal contract, an informal agreement can be legally binding. However, there must have been an ‘intention to create legal relations.’

According to, the High Court’s ruling confirmed an accepted principle in English contract law. wrote:

“There is a general accepted rule in English contract law that informal agreements can be binding between parties if there is an ‘intention to create legal relations’.”

“These agreements are most commonly inferred in a commercial context.”
