A caution for pursuing claims of Proprietary Estoppel and Undue Influence (Maile v Maile)
Private Client analysis: The High Court dismissed all probate claims against the Estate of Mary Stevens as well as the claimants' proprietary estoppel claim for title to the majority of the Estate. The court held that there is a high bar to prove unconscionability in a proprietary estoppel case and claimants should not take on the burden of proof lightly. The decision of James v James was followed, in that there is a distinction between unequivocal assurances that cannot be reneged without causing unconscionability, to statements of a testator's present intention. The court also reaffirmed the principle in Horsford v Horsford–that if the claimant is in partnership with the promisor, this is likely to be detrimental to a claim for proprietary estoppel, because, in an arms' length partnership agreement, they have effectively contracted out of the equitable remedies. The Court also emphasised that undue influence is an extremely serious allegation to make, particularly against a solicitor with nothing to gain from the alleged coercion and should not be relied upon as a fallback argument.
