Balfour v Balfour [1919] is the seminal authority establishing the rebuttable presumption that domestic and social agreements are not intended to be legally binding. The ruling serves a critical policy function, preventing courts from being overwhelmed by private, everyday arrangements between family members.

Facts of the Case

The case involved a husband and wife who entered into an agreement regarding a monthly allowance while the husband was working abroad. When the husband failed to keep up with the payments, the wife sued to enforce the arrangement. At the time the arrangement was made, the parties were a married couple living together.

Legal Issues

The central issue was whether the agreement between the spouses constituted a legally enforceable contract. Specifically, the court had to decide if the parties had an intention to create legal relations, which is an essential element of a binding contract alongside agreement and consideration.

Judgement

The Court of Appeal ruled in favour of the husband, finding that no binding contract existed. The court held that agreements between spouses regarding domestic matters are generally not intended to have legal consequences. Atkin LJ provided two primary reasons:

  • Lack of intent: he noted that such parties, at the inception of their arrangement, “never intended that they should be sued upon”.
  • Public policy: he argued that the legal system would be “inundated with claims” if every small domestic arrangement resulted in a legal obligation.

Authority and Significance

This case is the leading authority for the presumption governing contractual intention in non-commercial settings.

  • Presumption for domestic agreements: in domestic or social contexts, the law initially presumes the parties did not intend to be legally bound.
  • Rebuttable nature: unlike commercial agreements where intent is strongly presumed, the domestic presumption can be rebutted if the facts show a clear intention to be bound — such as when a couple has separated and is bargaining at arm’s length.
  • Contrast with commercial law: the case provides the necessary contrast to cases like Edwards v Skyways, where the court assumes a heavy burden of proof is required to show a lack of legal intent in business dealings.
