Formation of Contract in UK Law

The fact that the transaction was performed on both sides will often make it unrealistic to argue that there was no intention to enter into legal relations. It will often make it difficult to submit that the contract is void for vagueness or uncertainty. Specifically, the fact that the transaction is executed makes it easier to imply a term resolving any uncertainty, or, alternatively, it may make it possible to treat a matter not finalised in negotiations as inessential.

One must not lose sight of the commercial character of the transaction. It is not a case where there was a continuing stipulation that a contract would only come into existence if a written agreement was concluded. But I am, in any event, satisfied that in this fully executed transaction a contract came into existence during performance even if it cannot be precisely analysed in terms of offer and acceptance.

Whether there is a binding contract between the parties and, if so, upon what terms depends upon what they have agreed. It depends not upon their subjective state of mind, but upon a consideration of what was communicated between them by words or conduct, and whether that leads objectively to a conclusion that they intended to create legal relations and had agreed upon all the terms which they regarded or the law requires as essential for the formation of legally binding relations.

But it is not, in my judgment, necessary that the note or memorandum should acknowledge the existence of a contract.
