Variation of trusts
How courts and statute enable trustees to depart from the settler's original terms
Overview
The doctrine of variation of trusts represents a fundamental tension within equity between the sanctity of the settlor's intentions and the practical needs of beneficiaries in changed circumstances. Whilst the orthodox position maintains that trustees must adhere strictly to the terms set out in the trust instrument, both statute and the inherent jurisdiction of the court permit departures from these terms in specified circumstances. The Variation of Trusts Act 1958 provides the primary statutory mechanism, empowering the court to approve arrangements varying or revoking trusts on behalf of certain categories of beneficiaries who cannot consent for themselves.
The jurisdiction to vary trusts engages several foundational principles of trusts law. First, it challenges the traditional understanding that a settlor's intentions, once properly constituted in a trust, should be immutable. Second, it demonstrates the law's recognition that circumstances unforeseen by the settlor may render strict adherence to trust terms inappropriate or harmful to beneficiaries' interests. Third, it reveals the delicate balance courts must strike between protecting vulnerable beneficiaries and respecting adult beneficiaries' autonomy to make their own financial decisions.
Modern variation of trusts practice encompasses four distinct juridical bases: the inherent jurisdiction of the court (including maintenance, advancement, and compromise), the rule in Saunders v Vautier, statutory powers under the 1958 Act, and specific statutory provisions for particular types of trusts. Each operates according to different principles and subject to different limitations, creating a complex framework that practitioners must navigate carefully.
