Introduction
The law of trusts, a cornerstone of English equity, relies on the foundational principle of the ‘three certainties’ to establish a valid private express trust. These certainties—certainty of intention, certainty of subject matter, and certainty of objects—ensure that a trust is enforceable and that the intentions of the settlor are clear and actionable. While certainty of intention and subject matter are often regarded as relatively straightforward, the certainty of objects has proven far more complex, sparking significant debate among legal scholars and jurists. This essay critically evaluates the legal and judicial approaches to each of the three certainties, with reference to pivotal case law. It argues that while intention and subject matter can generally be determined with clarity, the certainty of objects poses unique challenges due to the evolving tests and judicial interpretations that shape its application. By examining key cases and scholarly perspectives, this essay seeks to highlight the strengths and limitations of the current legal framework in ensuring the validity of trusts.
Certainty of Intention: A Clear Foundation
Certainty of intention refers to the requirement that a settlor must demonstrate a clear intention to create a trust, distinguishing it from other legal arrangements such as gifts or contracts. This principle, as established in Knight v Knight (1840) 3 Beav 148, is typically straightforward, as courts look for explicit language or conduct indicating an intention to impose a binding obligation on the trustee. For instance, the use of imperative language such as ‘I direct’ or ‘I hold on trust’ often suffices to establish this certainty (Hudson, 2015). Moreover, in Paul v Constance [1977] 1 WLR 527, the court held that even informal language could suffice if the intent to create a trust was evident from the context, such as Mr. Constance repeatedly stating that money in a shared account was ‘as much hers as mine.’
However, despite its apparent simplicity, certainty of intention is not without challenges. Courts must sometimes grapple with ambiguous language or situations where precatory words—expressions of hope or desire—are used. In such cases, as seen in Lambe v Eames (1871) LR 6 Ch App 597, the court ruled that mere wishes do not create a trust, underscoring the need for a clear, binding intention. Generally, though, judicial approaches to this certainty have been consistent, focusing on the settlor’s objective intent. This renders certainty of intention a relatively uncontroversial requirement in trust law, with most disputes resolved through careful analysis of language and context.
Certainty of Subject Matter: Defining the Trust Property
Certainty of subject matter requires that the property to be held on trust must be clearly identified or identifiable. This principle ensures that trustees and beneficiaries can ascertain what constitutes the trust fund. The straightforward nature of this certainty was affirmed in Palmer v Simmonds (1854) 2 Drew 221, where the court invalidated a trust due to the vague description of the subject matter as ‘the bulk of my estate.’ Such imprecision prevents practical administration of the trust, rendering it unenforceable.
Nevertheless, judicial flexibility exists in cases where the subject matter can be made certain. For example, in Hunter v Moss [1994] 1 WLR 452, the court upheld a trust over 50 shares out of a larger holding of 950 identical shares, despite the specific shares not being segregated. This decision, while pragmatic, has attracted criticism for potentially undermining the need for strict certainty, as it allows trustees discretion that could complicate enforcement (Hudson, 2015). Despite such debates, the legal approach to subject matter remains broadly clear, with courts prioritising practicality where possible. Typically, therefore, this certainty poses fewer problems than its counterpart, certainty of objects, as the subject matter can often be clarified through evidence or judicial interpretation.
Certainty of Objects: A Complex and Contested Area
In contrast to the other certainties, certainty of objects—the requirement that beneficiaries of a trust must be clearly defined or ascertainable—presents significant complexity and has been the subject of considerable judicial and academic debate. This certainty ensures that trustees can identify who benefits from the trust and fulfil their obligations. The test for certainty of objects varies depending on whether the trust is fixed or discretionary, adding further layers of intricacy.
For fixed trusts, where beneficiaries have a direct entitlement to a share of the trust property, the test is stringent. As established in IRC v Broadway Cottages Trust [1955] Ch 20, a complete list of beneficiaries must be ascertainable for the trust to be valid. This ‘list certainty’ requirement, while clear, can be impractical in large or undefined beneficiary groups, leading to trusts being struck down. However, the test for discretionary trusts, where trustees have the power to select beneficiaries from a class, has evolved significantly. Initially, courts applied a strict approach, but the landmark decision in McPhail v Doulton [1971] AC 424 relaxed the test to one of ‘individual ascertainability.’ Under this test, it must be possible to say with certainty whether any given individual is or is not a member of the class of beneficiaries. This shift arguably made discretionary trusts more workable, reflecting a judicial willingness to adapt to modern settlor intentions (Pettit, 2012).
Despite this progress, the application of the McPhail test remains contentious. For instance, in R v District Auditor, ex parte West Yorkshire MCC [1986] RVR 24, a trust for the benefit of ‘the inhabitants of West Yorkshire’—a class of over two million people—was deemed void for administrative unworkability, even though individual ascertainability was theoretically possible. This highlights the courts’ struggle to balance conceptual clarity with practical enforceability. Furthermore, scholars such as Hudson (2015) argue that judicial discretion in defining ‘workability’ introduces inconsistency, as different judges may prioritise different practical concerns. Indeed, the complexity of certainty of objects lies in its dependence on subjective judicial interpretation, making it a far less straightforward requirement than intention or subject matter.
Conclusion
In conclusion, the three certainties of intention, subject matter, and objects form the bedrock of trust law in English equity, yet their application reveals varying degrees of complexity. Certainty of intention, while occasionally tested by ambiguous language, is generally clear and consistently applied by courts through objective analysis of the settlor’s words and actions. Similarly, certainty of subject matter benefits from judicial pragmatism, as seen in cases like Hunter v Moss, though it is not without criticism for perceived leniency. In stark contrast, certainty of objects remains a contentious and intricate requirement, with evolving tests and concepts such as ‘administrative unworkability’ complicating its application. Landmark cases like McPhail v Doulton demonstrate judicial efforts to balance flexibility with enforceability, yet inconsistencies persist, fuelling scholarly debate. Ultimately, while the legal framework for the three certainties provides a robust foundation for trusts, the challenges surrounding certainty of objects suggest a need for further clarification—perhaps through legislative reform or definitive judicial guidance—to enhance certainty and predictability in trust law.
