A compromise is itself a contract and must, as such, satisfy the ordinary requirements of contractual formation. The parties must reach agreement upon terms which are sufficiently certain and complete, objectively intend thereby to create legal relations and become immediately bound, and provide valuable consideration. Whether they have done so turns on what they conveyed to one another by words or conduct, viewed against the whole course of the negotiations and the relevant circumstances. Offer and acceptance remain the primary tools by which that inquiry is undertaken. They are not, however, exhaustive requirements to be applied mechanically; the ultimate question is whether the parties’ communications and conduct objectively disclose a concluded bargain (see G J Tolhurst and Elisabeth Peden, Furmston and Tolhurst on Contract Formation: Law and Practice (Oxford University Press, 3rd Ed, 2023) (“Furmston and Tolhurst”) at paras 1.01–1.02, 1.07–1.08, 1.17–1.20; also see, eg, Gay Choon Ing v Loh Sze Ti Terence Peter and another appeal [2009] 2 SLR(R) 332 at [46]–[53] and [60]–[63]). Where an issue arises as to whether an offer has been accepted, the general rule is that the acceptance takes no legal effect until it is properly communicated to the offeror or, at least, to someone authorised to receive it on the offeror’s behalf. From that rule, it follows that neither an uncommunicated decision to accept nor communication of that decision only to the offeree’s own agent ordinarily concludes the bargain (Furmston and Tolhurst at paras 4.54–4.56, 4.63; also see, eg, BGC Partners (Singapore) Ltd v Yap Yuk Hee and others [2021] SGHC 279 at [25]–[26] and [37]–[40]).
