WHEN do resulting trusts arise, and why? These questions were the subject of serious inquiry in the 1990s, following influential work by Peter Birks and Robert Chambers, which argued that resulting trusts arise to reverse unjust enrichment. The House of Lords in Westdeutsche Landesbank Girozentrale v Islington London Borough Council [1996] A.C. 669 remarked that the Birks/Chambers thesis was “avowedly experimental, written to test the temperature of the water”, but that “the temperature of the water must be regarded as decidedly cold”. Following Westdeutsche, the issue has received little consideration, although academic interest in the debate remains. The recent decision of the Singapore Court of Appeal in Chan Yuen Lan v See Fong Mun [2014] SGCA 36 considered this issue in detail and is therefore worth examining.
