Definition
An express trust is a trust intentionally created by a settlor through clear, deliberate expression of intent — as opposed to a trust that arises by operation of law from the circumstances of a transaction. The defining feature is that the settlor affirmatively manifests a purpose to create the trust relationship, naming (or sufficiently identifying) a trustee to hold property for the benefit of one or more beneficiaries.
Three elements are conventionally required: a present intent to create the trust, identifiable trust property (the res), and an ascertainable beneficiary or charitable purpose. The trust need not use any particular words, but the intent must be clear from the language used — whether written or, in limited contexts, oral.
Express trusts are the default subject of trust law. When practitioners, courts, and treatises refer to "trusts" without qualification, they almost always mean express trusts.
Common Confusion
Express trust is frequently contrasted with — and occasionally confused with — three other categories:
Implied trust: Arises from circumstances or presumed intent, not explicit declaration. An express trust that fails may give rise to an implied (resulting) trust.
Constructive trust: A remedial device imposed by equity to prevent unjust enrichment. It is not a "trust" in the full sense and involves no settlor intent whatsoever. Researchers who encounter "trust" language in equity decisions should confirm whether a court is enforcing an express trust or imposing a constructive one.
Active vs. passive (dry) trust: Burrill and Kent use "active trust" as a synonym for express trust, contrasting it with a passive or dry trust in which the trustee holds bare legal title with nothing meaningful to do. This older vocabulary appears in nineteenth-century equity cases and treatises. Modern law has largely abandoned the active/passive framing in favor of the express/implied/constructive taxonomy, but the older usage resurfaces in historical sources.
Core Elements
Because the elements of a valid express trust are contested at the margins and vary jurisdictionally, a structured breakdown serves researchers:
1. Intent to create a trust. The settlor must intend that a trust relationship — not a gift, agency, or contractual obligation — be created at the time of the declaration. Precatory language ("I wish," "I hope") is generally insufficient.
2. Trust property (res). The subject matter must exist and be identifiable. A trust of future property or mere expectancies typically fails until the property comes into existence and is transferred.
3. Trustee. A valid express trust requires a trustee capable of holding property. Equity will not allow a trust to fail for want of a trustee — courts will appoint one — but the trust must be otherwise complete.
4. Beneficiary (or charitable purpose). Private express trusts require at least one ascertainable beneficiary who can enforce the trust. Charitable trusts substitute a defined public purpose for identifiable individual beneficiaries.
5. Formalities. Express trusts of real property are subject to the Statute of Frauds in most common-law jurisdictions, requiring a writing signed by the party to be charged. Trusts of personal property may be created orally, though writing is standard and prudent. Testamentary trusts must comply with Wills Act formalities.
Why It Matters in Research
The express/implied distinction is foundational for trust research, but the vocabulary has shifted considerably across time and jurisdiction, creating real traps for corpus researchers.
Vocabulary drift. Pre-twentieth-century sources — including Burrill and Kent — use "active trust" interchangeably with "express trust." Searching for only one term in historical materials will miss a significant portion of relevant doctrine.
Resulting trusts as the shadow of failed express trusts. When an express trust fails — for indefinite beneficiaries, lack of res, or incomplete formalities — the property does not simply pass to the trustee. Equity typically raises a resulting trust back to the settlor or settlor's estate. Researchers analyzing failed express trusts must therefore also engage resulting trust doctrine. The Law Mind encyclopedia entry on resulting trusts (estates_67) covers this transition explicitly.
Statute of Frauds complications. Whether a given jurisdiction's Statute of Frauds applies to express trusts of personalty is an unsettled historical question. Nineteenth-century cases split sharply. Researchers tracking enforceability arguments should not assume uniformity across the corpus.
Testamentary vs. inter vivos classification. Express trusts divide critically by mode of creation — trusts declared during life (inter vivos) and trusts arising under a will (testamentary). The legal consequences differ substantially, particularly for formalities, revocability, and creditor access. Many historical sources treat these categories separately without cross-reference.
Constructive trust contamination. Courts occasionally use "express trust" loosely in older opinions to mean any trust that the court is treating as established, including what modern doctrine would classify as a constructive trust. Read trust characterizations in pre-twentieth-century decisions with care.
Historical Dictionary Support
The four source dictionaries converge on the core definition — an express trust is one declared in clear terms, as distinguished from a trust implied by law — but vary in what they add.
Burrill is the most useful. His entry identifies the active trust synonym, cites Kent's Commentaries (4 Kent's Com. 305, 310) as the leading authority, and flags the proof question, noting an Ohio State Reports citation for evidentiary issues. This is consistent with the mid-nineteenth-century equity framework in which express trusts were primarily creatures of chancery doctrine, not statute.
Black's entry is truncated in the provided source but aligns with Burrill's formulation.
Bouvier's is minimalist — "One declared in express terms. See TRUSTS" — which is typical of Bouvier's cross-referencing style. Researchers should follow his "See TRUSTS" redirect, where the substantive doctrine is developed.
Rapalje & Lawrence presents a data problem: the provided text conflates what appears to be material from multiple entries, including unrelated nuisance and maxim content. The Latin maxim fragment — Expositio, quæ ex visceribus causæ nascitur est aptissima et fortissima in lege ("That exposition which springs from the vitals of a cause is the fittest and most powerful in law") — is a real interpretive canon of some relevance to trust construction disputes, but it is not part of the express trust entry proper. Researchers should treat Rapalje & Lawrence's entry on this term with caution.
What the historical dictionaries collectively miss: they do not address the Statute of Frauds requirements in any systematic way, do not distinguish inter vivos from testamentary express trusts, and predate the Restatement framework that now organizes American trust doctrine. Modern research cannot rely on these entries alone.
Jurisdictional Note
American express trust doctrine has been substantially harmonized by the Uniform Trust Code (adopted in the majority of states) and the Restatement (Third) of Trusts, but significant variation persists in formality requirements, the enforceability of oral trusts of personalty, and the treatment of honorary trusts and trusts for non-charitable purposes. English law, the historical source of equity doctrine reflected in all four dictionaries, has diverged from American law on several points — particularly regarding trustee duties and the rule against perpetuities — and historical English authorities should not be imported into American jurisdictional analyses without checking for reception.
