A trust is a single equitable idea — an obligation annexed to ownership, compelling one person to hold property for the benefit of another — yet the law sorts it into many species depending on how it arose and whom it serves. The two great axes are purpose (public versus private) and origin (express, implied, constructive, resulting). Section 3 of the Indian Trusts Act, 1882 captures only the express trust; the implied, constructive and resulting varieties drift in from English equity, surfacing in Indian law as "obligations in the nature of trusts" under Chapter IX. For the judiciary and CLAT-PG aspirant, mastering these classifications is the gateway to the entire law of trusts, fiduciary duty and charitable endowment.
Why Classify Trusts at All
The trust is a creature of equity, and equity classifies not for taxonomy's sake but because the consequences turn on the category. Whether formalities are required, who may enforce the obligation, whether the Indian Trusts Act, 1882 even applies, and whether the cy-près doctrine can rescue a failing gift — all depend on which kind of trust is before the court. Section 3 of the Act defines a trust as "an obligation annexed to the ownership of property, and arising out of a confidence reposed in and accepted by the owner... for the benefit of another, or of another and the owner." The phrase "reposed in and accepted by" is decisive: it confines the statutory definition to express trusts, leaving implied, constructive and resulting trusts to be governed by general equitable principle, partly codified in Chapter IX as "obligations in the nature of trusts."
Three actors recur throughout: the author of the trust (settlor) who reposes the confidence, the trustee who accepts it, and the beneficiary for whose benefit it is held. The classifications below cut across this triad in different ways. The first cut is by purpose; the rest are by mode of creation. Before reading on, it helps to have absorbed the broader equitable backdrop in our introduction to equity and trusts, because every species of trust is ultimately a working-out of the maxim that equity will not permit a confidence to be abused.
Public and Private Trusts
The most consequential division is between private and public trusts, and it turns entirely on the character of the beneficiaries. A private trust confers benefit on certain ascertained persons or a determinate class — even if some incidental benefit spills over to the public. A public trust confers benefit on the public at large or a sufficiently large and indefinite section of it; it exists to serve some considerable portion of the community and typically takes a charitable, religious or purpose form.
The classic Indian statement is in Mahant Srinivas Ramanuj Das v. Surajnarayan Das, AIR 1967 SC 256, where the Supreme Court observed that in a private trust the beneficial interest is vested absolutely in one or more individuals who can be ascertained, whereas a public trust confers benefits on members of an uncertain or fluctuating body. The point was sharpened in Deoki Nandan v. Murlidhar, AIR 1957 SC 133: the distinction is that in a private trust the beneficiaries are specific individuals, while in a public trust they are the general public or a class thereof; in the former the beneficiaries are ascertained or capable of being ascertained, in the latter they constitute a body incapable of ascertainment. The Court added the practical test for religious endowments — whether the founder intended specified individuals or the general public (or a specified portion) to have the right of worship.
The division also fixes the reach of the Act itself. By Section 1, the Indian Trusts Act does not apply to public or private religious or charitable endowments. The Supreme Court confirmed in Thayarammal v. Kanakammal, (2005) 1 SCC 457 that the Act, by its Preamble and contents, governs private trusts only, and that a Hindu dedication for religious or charitable purposes is neither a gift nor a trust in the strict legal sense — the dedicated property may instead be raised to the category of a juristic person. Public charitable and religious trusts are therefore governed by separate statutes and general principles, not by the 1882 Act.
Express Trusts
An express trust is one created by the deliberate words of the settlor, whether written or verbal — not by inference from facts and circumstances. In Fitzgerald v. Steward the court held that an express trust is one created not by facts and circumstances but by express words; such trusts are also called declared trusts. This is the only species fully within Section 3, because only here is there a confidence "reposed in and accepted by" the owner with a clear declared intention.
Express trusts subdivide into executed and executory trusts. An executed (or perfect) trust requires no further act of the settlor: the trustee's duties to the beneficiaries are fully and clearly mapped out, and the trustee simply performs. An executory (or imperfect) trust is one where some additional direction by the settlor is still required before the trustee can fulfil the obligations — the settlor has indicated the broad intention but left details to be supplied. The distinction matters in construction: courts construe executed trusts strictly by the words used, but construe executory trusts more liberally to give effect to the settlor's underlying intention, a direct application of the maxim that equity looks to the intent rather than the form.
The Three Certainties for an Express Trust
Because an express trust depends on a declared intention, equity insists on certainty before it will fasten the obligation. The settled rule comes from Knight v. Knight, (1840) 49 ER 58, where Lord Langdale MR laid down the three certainties: certainty of intention to create a trust, certainty of subject-matter (the trust property), and certainty of objects (the beneficiaries). The dispute itself arose from precatory language in a will, and Lord Langdale held that words such as "trust to the liberality" of the recipient were precatory, not imperative, and so failed to impose any enforceable obligation.
Indian law adopts the same requirement. Section 6 of the Indian Trusts Act, 1882 provides that a trust is created when the author indicates with reasonable certainty an intention to create a trust, the purpose, the beneficiary and the trust-property, and transfers the property to the trustee. The notes occasionally speak of "four certainties" by splitting purpose from object, but the orthodox statement is the threefold Knight v. Knight formulation. If certainty of intention is absent, no trust arises and the transferee takes the property beneficially for himself — the very outcome equity reaches in the precatory-words cases discussed below.
Implied (Presumed) Trusts
An implied trust is gathered from the presumed intention of the settlor rather than from express words. It is neither written nor spoken but raised by construction of law from the acts and conduct of the parties — hence the alternative name, presumptive trust. The defining contrast with an express trust is the source of the obligation: an express trust is created by the express declarations of the parties, an implied trust by operation of law inferring what the owner must have intended.
Because the obligation here does not arise "out of a confidence reposed in and accepted by the owner" in the Section 3 sense, implied trusts fall outside the statutory definition and are treated, with constructive and resulting trusts, as obligations in the nature of trusts under Chapter IX of the Act. The category is a bridge between the wholly intentional express trust and the wholly imposed constructive trust: it rests on intention, but on intention inferred rather than declared.
Resulting Trusts
A resulting trust is a species of implied trust in which equity regards property held by a trustee as belonging in equity to the person who transferred it. It arises where the circumstances raise an inference that the transferor did not intend the holder of the legal title to take the beneficial interest, so the beneficial interest "results" — jumps back — to the transferor or his legal representatives. The classic trigger is failure of the object of the trust.
The textbook illustration: if X settles Rs 1,00,000 for the maintenance of A, but A dies before any of it is spent, the fund is held on a resulting trust for X or his legal representatives — equity will not let the trustee keep what was never meant for him. Resulting trusts also arise on a voluntary conveyance where no beneficial gift was intended, and where a trust is incompletely disposed of, leaving a surplus. In India, before the Benami Transactions (Prohibition) Act, 1988, the purchase-money resulting trust was reflected in Sections 81 and 82 of the Indian Trusts Act; those provisions were repealed with effect from 19 May 1988, so the purchase-money variety no longer operates as it once did. The doctrine is a direct working of the principle that equity acts in personam upon the conscience of the legal owner, refusing to let bare legal title defeat the true beneficial entitlement.
Constructive Trusts
A constructive trust arises purely by operation of law, imposed by courts to prevent injustice and irrespective of the parties' intention. As Snell put it, a constructive trust is raised by construction of equity to satisfy the demands of justice, without reference to any presumable intention of the parties, whether express or implied. Cardozo J's celebrated formulation is that a constructive trust is "the formula through which the conscience of equity finds expression." Where it would be an abuse of confidence for the legal owner to hold property for his own benefit, equity fastens a trust on him whatever his actual intention.
The foundational authority is Keech v. Sandford, (1726) Sel Cas King 61, where a trustee held a lease of Romford Market for an infant beneficiary. The landlord refused to renew to the infant but agreed to renew to the trustee personally, who took the new lease and profited. Lord King LC held that the trustee, though guilty of no fraud or bad faith, must hold the renewed lease on constructive trust and account for the profit — a trustee may not take for himself an opportunity connected with the trust property. The rule extends to all persons acting in a fiduciary capacity, not trustees alone, and is the equitable engine behind the no-profit and no-conflict rules. Constructive trusts differ from express trusts in two ways: they arise by operation of law rather than declaration, and they require no formalities; they differ from implied trusts in that they are imposed irrespective of intention, whereas implied trusts rest on presumed intention.
Chapter IX — Obligations in the Nature of Trusts
Indian drafting consciously avoided the English fiction of "constructive trusts." Chapter IX of the Indian Trusts Act, 1882 (Sections 80 to 96), headed "Of Certain Obligations in the Nature of Trusts," treats these confidences not as trusts proper but as obligations resembling trusts, thereby sidestepping the doctrine of double ownership that English equity presupposes. Section 80 opens the chapter, declaring that an obligation in the nature of a trust is created in the cases that follow.
The chapter once codified the purchase-money resulting trust (Section 81) and the resulting trust on a transfer for an illegal purpose or where the trust fails to exhaust the property (Section 82), but both were repealed by the Benami Transactions (Prohibition) Act, 1988. The surviving sections continue to capture situations such as property obtained by fraud, a trustee gaining an advantage in derogation of beneficiaries, and a person holding property without an intention to dispose of the beneficial interest. The reason these sit outside the Section 3 definition is structural: as Tagore v. Tagore, 9 BLR 377 established, the double-ownership idea is unknown in India — equitable ownership is not recognised, the trustee is the owner of the trust property when it vests in him, and the Indian beneficiary has only rights against the trustee, not an equitable estate.
Precatory Trusts
A precatory trust is one expressed not in clear mandatory terms but through words of request, hope or desire — "I hope," "I wish," "I desire," "in full confidence that." According to Underhill, trusts arising from precatory words are essentially express trusts conveyed through ambiguous and uncertain language. The whole question is one of construction: do the words, read objectively, impose a binding obligation, or merely express a moral wish that leaves the donee free?
The modern law turns decisively against finding a trust from precatory words. In Lambe v. Eames, (1871) LR 6 Ch App 597, a testator gave his estate to his widow "to be at her disposal in any way she may think best, for the benefit of herself and her family." The court held these were precatory words that did not create a trust, marking the turning point from the older indulgence towards precatory language to the modern insistence on imperative words. This dovetails exactly with the certainty-of-intention limb of Knight v. Knight: where the language is merely hortatory, certainty of intention fails and no trust arises. The lesson for the draftsman is plain — a trust must command, not merely hope.
Secret Trusts
A secret trust is a species of express trust not disclosed on the face of the will. A testator bequeaths property to a legatee on the legatee's promise to hold it in trust for some other person, the trust being kept off the instrument. There is an undertaking between testator and legatee that the property, though apparently given absolutely, shall in fact be held for a third party — an undertaking not clothed with the formalities that ordinarily attend the creation of a trust.
Equity enforces such trusts to prevent the legatee from fraudulently keeping property he accepted only on the faith of a promise; the maxim that equity will not allow a statute to be used as an instrument of fraud underlies their enforcement, since otherwise the Wills Act formalities would shield the dishonest legatee. Secret trusts are conventionally divided into fully secret trusts (neither the existence nor terms appear in the will) and half-secret trusts (the will discloses that the legatee takes as trustee but conceals the terms).
Trust for Value, Voluntary and Illusory Trusts
Classifying by consideration yields three further species. A trust for value is created in return for consideration moving from the beneficiary, so the relationship between settlor and beneficiary is essentially contractual — as where X settles property on A in consideration of A reducing a debt. A voluntary trust is created for no consideration at all; it is perfectly valid, since equity does not require consideration to support a completely constituted trust — A may settle property on B though B gives nothing in return. (The qualification is that equity will not perfect an imperfectly constituted voluntary trust: equity will not assist a volunteer.)
An illusory trust is, despite the name, scarcely a trust at all. Here the supposed beneficiaries cannot compel the trustee to perform; the trustee is free to deal with the property as he wishes, and the surrounding circumstances reveal that the settlor's real object was his own convenience rather than the benefit of the named persons. Because there is no genuine intention to benefit the apparent beneficiaries, equity will not compel performance — the arrangement only wears the costume of a trust.
Simple and Special Trusts
A final structural division turns on the trustee's role. In a simple trust (also called a bare trust), property is vested in the trustee but no particular duties are prescribed by the settlor; the trustee is a mere depository, and the construction of law fills the gap. The beneficiary has the right to be put into possession of the trust property and to demand a conveyance from the trustee, who must act according to the beneficiary's directions. The trustee here has, in effect, no active management role.
A special trust, by contrast, is one in which the settlor confers active duties on the trustee — to manage, invest, sell or otherwise deal with the property for the beneficiary's benefit. Special trusts are sometimes further described as ministerial (involving no exercise of discretion, only the carrying out of defined acts) or discretionary (calling for the exercise of judgment by the trustee). The distinction matters most when a beneficiary seeks to call for the property: under a bare trust the beneficiary of full capacity may generally demand transfer and end the trust, a principle of considerable practical importance in estate planning.
Charitable Trusts and Cy-près
The most important sub-class of public trust is the charitable trust — a trust for a purpose the law regards as beneficial to the general community. A charity must benefit an indefinite number of persons drawn from a definite class, community or section of the public, and not private individuals; this public-benefit element is precisely what divides a charity from a private trust, echoing the beneficiary test of Deoki Nandan v. Murlidhar.
The heads of charity were authoritatively catalogued by Lord Macnaghten in Commissioners for Special Purposes of Income Tax v. Pemsel, [1891] AC 531 (the notes' "Pamsell" is a misspelling of Pemsel): trusts for the relief of poverty; for the advancement of education; for the advancement of religion; and for other purposes beneficial to the community not falling under the preceding heads. Charitable trusts enjoy a unique privilege — the cy-près doctrine, from the Norman French for "as near as possible." Where a gift is clearly for charitable purposes only, equity will not let it fail merely because the precise object or mode of application is uncertain or has become impossible; the court applies the fund to a purpose as near as possible to the settlor's original intention. The doctrine operates where the general charitable purpose is expressed but the specific mode is left uncertain, where a gift to a particular charity becomes incapable of taking effect, and where the charitable purpose does not exhaust the property. Its limit is strict: cy-près applies only where carrying out the testator's exact intention is impossible, and the new purpose must approximate the original as nearly as possible.
Trust Distinguished — Bailment and Agency
Identifying the kind of trust also means knowing what is not a trust. A bailment is recognised at common law and gives the bailee only legal rights over chattels; the bailor passes only a limited or special interest, and a bailee selling without authority passes no good title against the bailor. A trustee, by contrast, holds equitable obligations over any kind of property as full legal owner, and an unauthorised sale by a trustee can confer good title on a bona fide purchaser for value without notice — the doctrine of the equity's darling. Crucially, only the bailor can enforce a bailment, whereas a trust obligation may be enforced by anyone entitled to its benefit.
An agency normally arises by contract; the principal's property does not vest in the agent, the agent can bind the principal in liability, and the agent acts under the principal's control and derives authority by delegation. A trust generally involves no contract between trustee and beneficiary; the trust property vests in the trustee, who cannot involve the beneficiaries in liability, is not subject to their control, and derives authority from the instrument of trust. These distinctions matter because the law of trusts attaches consequences — fiduciary duties, the right of any beneficiary to sue, the immunity of the bona fide purchaser — that simply do not follow from bailment or agency.
Frequently asked questions
What is the basic difference between a public and a private trust?
A private trust benefits ascertained individuals or a determinate class, while a public trust benefits the general public or an indefinite section of it. In Deoki Nandan v. Murlidhar, AIR 1957 SC 133, the Supreme Court held that private-trust beneficiaries are specific and capable of ascertainment, whereas public-trust beneficiaries form a body incapable of ascertainment. Mahant Srinivas Ramanuj Das v. Surajnarayan Das, AIR 1967 SC 256, makes the same point in terms of an uncertain or fluctuating body.
Which kinds of trust fall outside the definition in Section 3 of the Indian Trusts Act?
Section 3 covers only express trusts, because it requires a confidence "reposed in and accepted by" the owner. Implied, constructive and resulting trusts arise by operation of law and are dealt with separately as "obligations in the nature of trusts" under Chapter IX (Sections 80 to 96). Public and private religious or charitable endowments are excluded altogether by Section 1, as confirmed in Thayarammal v. Kanakammal, (2005) 1 SCC 457.
How does a constructive trust differ from a resulting trust?
A resulting trust is a species of implied trust resting on the transferor's presumed intention — the beneficial interest "results" back to him, as where a settled fund fails because its object dies. A constructive trust is imposed by the court irrespective of intention to prevent unjust enrichment or abuse of confidence, as in Keech v. Sandford, (1726) Sel Cas King 61, where a trustee who renewed a trust lease for himself was made to hold it on constructive trust.
What are the three certainties required for an express trust?
From Knight v. Knight, (1840) 49 ER 58, an express trust requires certainty of intention to create a trust, certainty of subject-matter (the trust property) and certainty of objects (the beneficiaries). Section 6 of the Indian Trusts Act, 1882 embodies the same requirement. If certainty of intention fails — typically because the words are merely precatory — no trust arises and the transferee takes beneficially.
Do precatory words like 'I hope' or 'I wish' create a trust?
Generally no. Since Lambe v. Eames, (1871) LR 6 Ch App 597, courts require imperative words that impose a binding obligation, not mere expressions of hope or desire. There, a gift to a widow "to be at her disposal in any way she may think best for the benefit of herself and her family" was held precatory and created no trust. A precatory trust will be found only where the language, construed objectively, still discloses an imperative intention.
What is the cy-près doctrine and when does it apply?
Cy-près ("as near as possible") allows a court to apply a charitable fund to a purpose closely resembling the settlor's original one where the precise object becomes uncertain or impossible, so that a clearly charitable gift does not fail. It applies where the general charitable purpose is expressed but the mode is uncertain, where a gift to a particular charity cannot take effect, and where the charitable purpose leaves surplus property. It operates only where carrying out the exact intention is strictly impossible, and the substituted purpose must approximate the original as nearly as possible.
