Private Client analysis: Teixeira v Moaven confirms the continued importance of the sham trust doctrine where declarations of trust are used to misrepresent beneficial ownership. The High Court held that the declarations were shams and, in any event, would have been liable to be set aside under section 423 of the Insolvency Act 1986 (IA 1986). The judgment also provides significant guidance on when personal representatives should adopt an active role in estate litigation and suggests, following THG v Zedra, that section 423 claims are not subject to statutory limitation. The decision will be of particular interest to trusts, estates and contentious probate practitioners. Produced in partnership with Zachariah Pullar, barrister at Guildhall Chambers.
