Revise Intention to create legal relations for Cambridge 9084 (3.1.3)

For a binding contract to exist, the parties must have intended their agreement to be legally enforceable. This is known as the 'intention to create legal relations' or 'animus contrahendi'. It is a distinct requirement alongside offer, acceptance, and consideration. The test for this intention is objective: the court does not ask what the parties privately thought, but what a reasonable person would conclude from their words and actions in the circumstances. This doctrine serves a crucial public policy function by preventing the courts from being overwhelmed with disputes arising from purely social or domestic arrangements. It acts as a filter, ensuring that only agreements intended to have legal consequences are brought before the law for enforcement.

In agreements made between family members, friends, or in other social contexts, the law starts with a rebuttable presumption that there is no intention to create legal relations. The courts assume that these arrangements are based on trust and affection, not legal obligation. The classic authority is Balfour v Balfour (1919), where a husband's promise to pay his wife a maintenance allowance while he worked abroad was held not to be a contract. Lord Atkin stated that such domestic arrangements are outside the realm of contracts. Similarly, in Jones v Padavatton (1969), an agreement for a mother to support her daughter through her Bar studies by providing a house was deemed a family arrangement lacking legal intent, despite the significant financial commitments involved. However, social agreements can sometimes be binding, as in Simpkins v Pays (1955), where a lodger, a grandmother, and her granddaughter had a clear mutual arrangement to share winnings from a newspaper competition they entered weekly.

The presumption against legal intent in domestic agreements can be overturned (rebutted) by clear evidence to the contrary. The court will look for factors that suggest the parties intended their agreement to have legal force. A key factor is the context of the relationship at the time of the agreement. In Merritt v Merritt (1970), an agreement between a separated husband and wife was held to be binding because they were no longer in a state of amity and were dealing with each other 'at arm's length'. Other factors include the presence of a formal written agreement, and whether a party has acted to their significant detriment in reliance on the promise. This was crucial in Parker v Clark (1960), where a couple sold their home and moved in with their elderly relatives based on a promise they would inherit the house. The court held this significant reliance rebutted the presumption.

In the commercial or business sphere, the presumption is reversed. The law presumes that when parties enter into a business agreement, they intend it to be legally binding. This approach provides certainty and security, which are essential for commerce to function effectively. The presumption is very strong. In Edwards v Skyways Ltd (1964), an employer's promise to make an 'ex gratia' payment to a redundant pilot was held to be binding, despite the term 'ex gratia' suggesting a non-obligatory gift. The court ruled the business context meant a legal obligation was intended. Similarly, in Esso Petroleum Ltd v Commissioners of Customs and Excise (1976), the House of Lords held that Esso's promotion offering a 'free' World Cup coin with every four gallons of petrol did have an intention to create legal relations. Although the coins had little value, the promotion was a business transaction to increase sales, and the presumption of legal intent applied.

Although the commercial presumption is strong, it can be rebutted by clear and express words indicating that the parties did not intend to be legally bound. Such clauses are often referred to as 'honour clauses' or 'gentlemen's agreements'. The leading case is Rose and Frank Co v JR Crompton and Bros Ltd (1925), where an agreement contained a specific clause stating it was 'not subject to legal jurisdiction' but was an 'honourable pledge' only. The court respected this clear language and held that the agreement was not a legally binding contract. Similarly, 'letters of comfort' given by a parent company may lack legal intent if their wording is not sufficiently promissory, as in Kleinwort Benson Ltd v Malaysia Mining Corp (1989), where the letter was seen as a statement of present policy rather than a future promise. Finally, collective agreements between trade unions and employers are presumed not to be legally enforceable unless stated otherwise in writing, a principle now enshrined in UK statute.
