CANADA: Québec court re-states burden of proof in 'undue influence' claims

In Thivierge v Thivierge (2024 QCCA 54) the Québec Court of Appeal revisited the criteria that define undue influence and the burden that a party alleging undue influence must bear to prove their case. Overturning the first instance judgment, it held that it is not illicit or illegal to try to influence someone, even on their deathbed, and insofar as one person may influence another the influence was not necessarily undue unless proved so.
