“Here is the security agreement you asked for but you must take your own advice on it.”
“Plainly there are large areas where the two concepts do not overlap: when a landowner stands by while his neighbour mistakenly builds on the former’s land the situation is far removed (except for the element of unconscionable conduct) from that of a fiduciary who derives an improper advantage from his client.”
“I suggest that, in other cases of this kind, useful guidance may in the future be obtained from the principles underlying the law of proprietary estoppel which in my judgment are closely akin to those laid down in Gissing v Gissing. In both, the claimant must to the knowledge of the legal owner have acted in the belief that the claimant has or will obtain an interest in the property. In both, the claimant must have acted to his or her detriment in reliance on such belief. In both, equity acts on the conscience of the legal owner to prevent him from acting in an unconscionable manner by defeating the common intention. The two principles have been developed separately without cross-fertilisation between them; but they rest on the same foundation and have on all other matters reached the same conclusions.”
“To recapitulate briefly: the species of constructive trust based on ‘common intention’ is established by what Lord Bridge in Lloyds Bank plc v Rosset[1991] 1 AC 107 at 132 called an ‘agreement, arrangement or understanding’ actually reached between the parties, and relied on and acted on by the claimant. A constructive trust of that sort is closely akin to, if not indistinguishable from, proprietary estoppel. Equity enforces it because it would be unconscionable for the other party to disregard the claimant’s rights. Section 2(5) expressly saves the creation and operation of a constructive trust.”
