“35. An inter vivos transaction can be set aside for undue influence, as a matter of public policy, even where there is no actual wrongdoing. The applicable principles are those laid down in Royal Bank of Scotland v Etridge (No. 2)[2001] UKHL 44 (HL) which can be summarised as follows:- • The issue the court is concerned with is the use of “unacceptable forms of persuasion” being employed by one person over another, to induce that other to enter into a transaction; • There are 2 such forms: “improper pressure or coercion, such as unlawful threats” and a second, which “arises out of a relationship between two persons, where one has acquired over the other a measure of influence, or ascendancy, of which the ascendant person then takes unfair advantage”; • The law will intervene to prevent abuse of influence in “relationship” cases, even in the absence of overt acts of persuasive conduct; • Equity is particularly concerned about those relationships where one party is disposed to do whatever the other asks without exercising independent judgment, usually occurring where one party has placed trust in another to look after his affairs and interests. In this class of case, it is the duty of one party to advise the other or to manage his property for him; • Relationship cases are properly to be identified by asking whether one party has reposed sufficient trust and confidence in the other, rather than whether the relationship belongs to a particular type (e.g., parent and child); but • The principle is not confined to cases of trust and confidence. It can include reliance, dependence or vulnerability on one side and ascendancy, domination or control on the other side. Even this is not to be taken as a comprehensive definition; • The party asserting undue influence has the burden of proof (i.e., Paul). However, if they make out the appropriate relationship and a transaction which cannot readily be explained by the ordinary motives of ordinary persons in that relationship, the court will then infer that the transaction can only have been procured by undue influence. It is then for the party alleged to have exercised undue influence (i.e., Boris) to produce evidence to counter this inference; • Instead of speaking of “the presumption of undue influence”, the better language now is to say that there is “a rebuttable evidential presumption of undue influence”; • This is to be distinguished from “presumed undue influence”
