"There is no serious dispute about the law. The approach that I should adopt may be summarised as follows: i) In a case of a testamentary disposition of assets, unlike a lifetime disposition, there is no presumption of undue influence; ii) Whether undue influence has procured the execution of a will is therefore a question of fact; iii) The burden of proving it lies on the person who asserts it. It is not enough to prove that the facts are consistent with the hypothesis of undue influence. What must be shown is that the facts are inconsistent with any other hypothesis. In the modern law this is, perhaps no more than a reminder of the high burden, even on the civil standard, that a claimant bears in proving undue influence as vitiating a testamentary disposition; iv) In this context undue influence means influence exercised either by coercion, in the sense that the testator's will must be overborne, or by fraud. v) Coercion is pressure that overpowers the volition without convincing the testator's judgment. It is to be distinguished from mere persuasion, appeals to ties of affection or pity for future destitution, all of which are legitimate. Pressure which causes a testator to succumb for the sake of a quiet life, if carried to an extent that overbears the testator's free judgment discretion or wishes, is enough to amount to coercion in this sense; vi) The physical and mental strength of the testator are relevant factors in determining how much pressure is necessary in order to overbear the will. The will of a weak and ill person may be more easily overborne than that of a hale and hearty one. As was said in one case simply to talk to a weak and feeble testator may so fatigue the brain that a sick person may be induced for quietness' sake to do anything. A "drip drip" approach may be highly effective in sapping the will; vii) There is a separate ground for avoiding a testamentary disposition on the ground of fraud. The shorthand used to refer to this species of fraud is "fraudulent calumny"
