Of the twelve classical maxims, He who seeks equity must do equity is the one that most plainly reveals the conscience-based character of the Chancellor's jurisdiction. It tells a plaintiff knocking on the door of equity that relief is never unconditional: the price of an equitable decree is a willingness to recognise and satisfy whatever countervailing claims fairness demands in his adversary's favour. Where the common law granted or refused a remedy as of right, equity granted it on terms. For the Indian judiciary and CLAT-PG aspirant, the maxim is doubly important because it is not a dead English relic but a living principle codified across the Transfer of Property Act, the Specific Relief Act, the Indian Contract Act and the Indian Trusts Act, 1882, where it surfaces as the doctrine of election, the statutory power to impose terms on rescission, and the equitable conditions attached to a beneficiary's relief against a defaulting trustee.

The Core Meaning: Reciprocity as a Condition of Relief

The maxim means that a litigant who asks a court of equity to enforce a claim must himself be prepared to do equity — that is, to acknowledge and submit to whatever corresponding obligations fairness imposes on him in favour of the defendant. It rests on the golden rule restated in juristic form: do unto your neighbour what you would have him do unto you. Equity, which had no power to act in rem but only on the conscience of the person before it, would not lend its extraordinary aid to a plaintiff who himself sought to escape the burdens of the very transaction whose benefit he claimed.

The classic judicial statement is found in the principle that a man who comes to seek the aid of a court of equity to enforce a claim must be prepared to submit, in such proceedings, to any directions which the known principles of a court of equity may make it proper to give; he must do justice as to the matters in respect of which the assistance of equity is asked. The relief is therefore conditional. The Chancellor does not say "yes" or "no" but "yes, upon terms". This is the maxim's signature: it operates as a brake on the plaintiff's own demand, requiring reciprocity before the decree issues. As a maxim that supplements rather than overrides the law — in line with the twelve classical maxims and the principle that equity follows the law — it tempers the rigour of strict legal entitlement with the requirement of mutual fairness.

Looking Forward, Not Backward: Distinction from Clean Hands

A point of constant confusion in examinations is the boundary between this maxim and its sibling, he who comes into equity must come with clean hands. The two are easily distinguished once their temporal direction is grasped. The clean-hands maxim looks backward: it scrutinises the plaintiff's past conduct in relation to the very transaction sued upon, and bars relief altogether if that conduct was tainted by fraud, illegality or bad faith. By contrast, he who seeks equity must do equity looks forward: it is unconcerned with antecedent misconduct and instead fixes the conditions on which relief, once available, will be granted. It governs the plaintiff's conduct inside the court and thereafter, not before he comes to it.

The practical consequence is significant. Clean hands is a complete defence — if it applies, the plaintiff is turned away empty-handed. The present maxim is not a defence at all but a qualification of the decree: the plaintiff still wins, but only if he accepts the equitable terms the court annexes. A plaintiff who refuses those terms forfeits the relief, yet the bar is of his own making, not a punishment for prior wrongdoing.

Cooper v Phibbs: Relief Conditioned on a Lien

The leading English illustration is Cooper v Phibbs (1867) LR 2 HL 149, a decision of the House of Lords. Cooper, acting on the belief — honestly conveyed by his late uncle — that the uncle had owned a salmon fishery, entered into an agreement to take a lease of the fishery from the uncle's daughters. In fact, under the family settlements, Cooper himself was already the beneficial owner of the fishery; a man cannot take a lease of his own property. The agreement had proceeded upon a common mistake as to the parties' respective rights, and Lord Westbury held it liable to be set aside in equity, the lease being voidable rather than void because the mistake went to beneficial rather than legal title.

What makes the case the textbook authority for this maxim is the condition the House of Lords attached to the relief. Cooper obtained the setting aside of the agreement only subject to the respondents' lien for the sums their father had expended on improving the fishery, and subject to his accounting for occupation. He who sought the equitable relief of rescission was made to do equity by recognising the respondents' legitimate claim to recoup their outlay. The decree, in other words, came on terms — the very signature of the maxim.

Lodge v National Union Investment: Equity Despite Illegality

An even sharper illustration is Lodge v National Union Investment Co Ltd [1907] 1 Ch 300, decided by Parker J. A borrower (Lodge) had taken loans from an unregistered moneylender and mortgaged securities to him. Under the Moneylenders Act, 1900, the contracts were illegal and void; the moneylender could not enforce them. Lodge then sued in equity to recover his securities, contending that since the contracts were void he was entitled to their return free of any obligation to repay.

Parker J refused to make the order except on the terms that Lodge should repay the money actually advanced to him. Although the borrower had a good legal point — the lending contract was indeed void — he was now seeking equity, and equity would not assist him to recover his property while keeping the loan money. The court would compel him to do what was right and fair. The case is a powerful demonstration that the maxim can require a plaintiff to honour a moral obligation even where the underlying legal obligation has been struck down by statute, provided he chooses to invoke the equitable jurisdiction. Equity, in such a posture, refuses to be made the instrument of a one-sided advantage.

The Maxim in Indian Statute Law

Indian law recognises no formal distinction between law and equity as understood in the English system — the dual court structure of King's Bench and Chancery never existed here. As traced in our note on equity in India before and after Independence, the equitable principles were instead absorbed into the codified statutes. He who seeks equity must do equity is among the most thoroughly codified of the maxims, appearing in at least four central enactments.

It animates the doctrine of election in Section 35 of the Transfer of Property Act, 1882; the power of a court to impose restitutionary terms on rescission and cancellation under Sections 30 and 33 of the Specific Relief Act, 1963; the statutory duty of restoration on rescission of voidable and void agreements under Sections 64 and 65 of the Indian Contract Act, 1872; and the equitable conditions attached to a beneficiary's or transferor's relief under Sections 62 and 86 of the Indian Trusts Act, 1882. Far from being a museum piece, the maxim is the conceptual spine running through these scattered provisions, all of which insist that a party invoking the court's aid must restore what fairness requires.

Section 35 TPA: The Doctrine of Election

Section 35 of the Transfer of Property Act, 1882 embodies the doctrine of election, which is the most prominent statutory expression of this maxim. The doctrine rests on the rule against approbate and reprobate — captured in the maxim quod approbo non reprobo, "that which I approve I cannot disapprove". A person who takes a benefit under a deed, will or other instrument must adopt the whole of it: he must conform to all its provisions and renounce every right of his that is inconsistent with the instrument.

The classic situation is this: a transferor purports, in one instrument, to transfer property that does not belong to him but to a third person, and by the same instrument confers a benefit on that very owner. The owner is then put to his election. He may either confirm the transfer of his property and take the benefit conferred on him, or he may reject the transfer and retain his property — but if he does the latter, he must relinquish the benefit, which goes back towards making good the disappointed transferee's loss. He cannot both keep his own property and pocket the benefit; that would be to approbate and reprobate the same instrument. The doctrine is the maxim in action: he who seeks the benefit (equity) of the instrument must do equity by giving effect to the rest of it. The election may be express or implied, and acceptance of the benefit with knowledge of the duty to elect amounts to an election to confirm.

Section 30 Specific Relief Act: Terms on Rescission

Section 30 of the Specific Relief Act, 1963 is headed precisely in the language of the maxim — "Court may require parties rescinding to do equity". It provides that on adjudging the rescission of a contract, the court may require the party to whom such relief is granted to restore, so far as may be, any benefit which he may have received from the other party and to make any compensation to him which justice may require.

The provision is a direct statutory enactment of the principle vindicated in Cooper v Phibbs and Lodge v National Union Investment. A plaintiff cannot obtain the equitable relief of rescission — the unwinding of a contract — while retaining the fruits he has already drawn from it. The court is empowered, as a condition of the decree, to make him give back the benefit and pay compensation, so that the parties are restored, as nearly as may be, to their pre-contract positions. Rescission, being a discretionary equitable remedy, is thus moulded on terms rather than granted as an absolute right, and the discretion is exercised in service of mutual fairness.

Section 33 Specific Relief Act: Cancellation and Resistance of Instruments

Section 33 of the Specific Relief Act, 1963 carries the same equitable logic into the domain of cancellation of instruments. It empowers the court, on adjudging the cancellation of an instrument, to require the party to whom the relief is granted to restore any benefit received and to make compensation as justice requires. Crucially, sub-section (2) extends the principle to a defendant who successfully resists an instrument as void or voidable: where a party against whom an instrument is sought to be enforced resists it on the ground that it is void or voidable, the court may, if it finds the instrument void or voidable, require that party to restore, so far as may be, any benefit he has received under the instrument.

The reach of sub-section (2) is instructive. It applies the maxim even-handedly: a party who escapes the burdens of an instrument by having it declared void cannot simultaneously keep the advantages he drew from it. Whether one comes to equity as a plaintiff seeking cancellation or invokes equity defensively to resist enforcement, the price of that relief is restitution. This mirrors the result in Lodge, statutorily generalised.

Sections 64 and 65 Indian Contract Act: The Duty to Restore

The Indian Contract Act, 1872 codifies the same restitutionary instinct in Sections 64 and 65. Section 64 deals with the consequences of rescinding a voidable contract: the party who rescinds must, if he has received any benefit under the contract from the other party, restore that benefit, so far as may be, to the person from whom it was received. Section 65 governs agreements discovered to be void or contracts that become void: any person who has received an advantage under such an agreement or contract is bound to restore it, or to make compensation for it, to the person from whom he received it.

The Privy Council examined the contours of Section 64 in Murlidhar Chatterjee v International Film Co Ltd AIR 1943 PC 34, holding that a party putting an end to a contract under Section 39 was nonetheless bound by the restitutionary obligation in Section 64 to restore benefits received. The decision confirms that restitution under these sections is not a claim for damages but a claim for restoration — the aim being to place the parties, as far as possible, in the position they would have occupied had there been no contract. Both sections translate the maxim into a hard statutory duty: one cannot rescind or disavow a transaction yet retain what one gained under it.

Section 62 Indian Trusts Act: Beneficiary's Conditional Relief

The maxim threads directly through the Indian Trusts Act, 1882. Section 62 confers on the beneficiary a right where the trustee has wrongfully bought the trust property — a breach of the disability in Sections 52 and 53, which forbid a trustee whose duty it is to sell from buying, and bar a trustee from purchasing the beneficiary's interest without the court's permission. Under Section 62, the beneficiary may have the property declared still subject to the trust, or have it retransferred by the trustee if it remains unsold in his hands, or by a purchaser who took with notice of the trust.

But this beneficiary's remedy is not unconditional. Consistent with he who seeks equity must do equity, the court, in granting the declaration or retransfer, imposes an equitable condition: the beneficiary must repay to the trustee the purchase money the trustee actually paid, together with interest, and reimburse any other legitimate expenses or improvements. The beneficiary cannot recover the property and at the same time keep the value the trustee sank into acquiring it; he who seeks the trust property back must do equity to the trustee from whom he reclaims it. This is the maxim applied to the very heart of trust administration, sitting alongside the broader principle that equity, and the trust itself, acts in personam upon the conscience of the trustee.

Section 86 Indian Trusts Act: Restitution on a Rescindable Transfer

Section 86 of the Indian Trusts Act, 1882 carries the same condition into the field of obligations in the nature of trusts. Where property is transferred under a contract that is liable to rescission, or under a transfer induced by such a contract, and the transferor seeks to recover the property, Section 86 obliges the transferee to hold the property for the benefit of the transferor — but the transferor must, as an equitable condition of obtaining relief, repay to the transferee the consideration actually received by the transferor under the rescindable contract, together with interest.

The structural parallel with Section 62 and with Cooper v Phibbs is exact. A party invoking equity to undo a transaction and recover property must restore the consideration he obtained; otherwise he would be enriched at the other's expense, which equity will not countenance. Sections 62 and 86 together demonstrate that the framers of the 1882 Act consciously wove the maxim into the statutory fabric of trust law, ensuring that the beneficiary's and transferor's equitable rights are always balanced by a reciprocal duty of restitution.

Mortgage Redemption: Pay Before You Redeem

The law of mortgages furnishes a further everyday application. The mortgagor's right of redemption — the equity of redemption — is itself a creature of equity, developed to relieve against forfeiture under the maxim once a mortgage, always a mortgage. Yet a mortgagor who comes to equity to redeem must himself do equity: he cannot recover his property free of the debt, but must pay or tender the principal, interest and costs properly due to the mortgagee. He who seeks to redeem must satisfy what is owing.

The Supreme Court's discussion of the equity of redemption in Seth Ganga Dhar v Shankar Lal AIR 1958 SC 770 illustrates the equitable balancing involved. The Court struck down, as a clog on the equity of redemption, a clause providing that if the mortgagor failed to redeem within six months after an 85-year term the mortgage would operate as a sale — affirming that the right to redeem cannot be fettered or extinguished by oppressive stipulations. At the same time, the redemption the equity protects is always redemption on payment of what is due. The two ideas are complementary: equity will not allow the mortgagee to clog the right, but neither will it allow the mortgagor to redeem without doing equity by discharging the secured debt. The protection of the right and the price of its exercise are two faces of the same equitable coin.

Limits, Discretion and the Shape of the Decree

The maxim is not a licence for courts to impose arbitrary conditions. The terms annexed to relief must themselves flow from recognised equitable principles and must bear a genuine relationship to the relief sought. In Cooper v Phibbs the condition was the respondents' lien for improvements they had genuinely made; in Lodge it was repayment of money the plaintiff had genuinely received. The court does not extract concessions unrelated to the transaction before it; it requires the plaintiff to satisfy the legitimate, connected equities of the defendant.

It must also be remembered that in India the maxim operates through and within the codified statutes, not above them. As our note on the principle that equity will not suffer a wrong to be without a remedy explains, equitable maxims in India cannot override express statutory provisions. The conditions a court imposes under Sections 30 and 33 of the Specific Relief Act, or Sections 62 and 86 of the Trusts Act, are exercised within the discretion those very statutes confer. The maxim supplies the rationale; the statute supplies the authority. For a fuller map of the system within which this principle sits, see the introduction to equity and the equity and trust law hub.

Exam Strategy and Quick Recall

For judiciary mains and CLAT-PG, the maxim is best deployed by pairing the abstract statement with at least one English authority and one Indian statutory anchor. The safest combination is: Cooper v Phibbs (1867) LR 2 HL 149 and Lodge v National Union Investment Co Ltd [1907] 1 Ch 300 for the English illustrations, then Section 35 TPA (election), Sections 30 and 33 of the Specific Relief Act, 1963, Sections 64 and 65 of the Indian Contract Act, 1872, and Sections 62 and 86 of the Indian Trusts Act, 1882 for the Indian codification.

The single most marketable distinction in an answer is the prospective character of this maxim against the retrospective character of clean hands: the present maxim conditions relief on future fairness, whereas clean hands bars relief for past misconduct. Frame the maxim as one demanding reciprocity and restitution — a plaintiff who wants equity's help must restore benefits, pay what is due and submit to the legitimate counter-equities of his adversary — and you will capture both the doctrine and its statutory life in Indian law.

Frequently asked questions

What does the maxim 'he who seeks equity must do equity' mean?

It means that a litigant asking a court of equity to enforce a claim must himself be prepared to act fairly and to satisfy whatever corresponding obligations fairness imposes in the defendant's favour. Equitable relief is granted on terms, not as an absolute right, so the plaintiff must do justice as to the very matters on which he seeks the court's aid.

How does this maxim differ from 'he who comes into equity must come with clean hands'?

The maxims point in opposite temporal directions. Clean hands looks backward at the plaintiff's past conduct and bars relief altogether if that conduct was tainted. He who seeks equity must do equity looks forward and merely conditions relief on the plaintiff's willingness to act fairly going forward. The former is a complete defence; the latter is a qualification of the decree.

What is the significance of Cooper v Phibbs for this maxim?

In Cooper v Phibbs (1867) LR 2 HL 149 the House of Lords set aside a lease taken under a common mistake about ownership, but only on terms: the relief was conditioned on the respondents' lien for money spent improving the fishery and on the plaintiff accounting for occupation. It is the classic illustration that equitable relief comes on terms requiring the plaintiff to do equity.

How does Lodge v National Union Investment illustrate the maxim?

In Lodge v National Union Investment Co Ltd [1907] 1 Ch 300, Parker J allowed a borrower to recover securities mortgaged under a void moneylending contract only on the condition that he repay the money actually advanced. Although the contract was illegal and void, the borrower who sought equity's aid was required to do equity by returning the loan money.

Which Indian statutory provisions embody this maxim?

The maxim is codified in Section 35 of the Transfer of Property Act, 1882 (doctrine of election), Sections 30 and 33 of the Specific Relief Act, 1963 (terms on rescission and cancellation), Sections 64 and 65 of the Indian Contract Act, 1872 (restoration of benefits), and Sections 62 and 86 of the Indian Trusts Act, 1882 (equitable conditions on a beneficiary's or transferor's relief).

How does Section 62 of the Indian Trusts Act, 1882 apply the maxim?

Section 62 lets a beneficiary recover or have retransferred trust property that a trustee wrongfully bought. But the relief is conditional: consistent with the maxim, the court requires the beneficiary to repay the trustee the purchase money with interest and to reimburse legitimate expenses. The beneficiary cannot reclaim the property while keeping the value the trustee invested in acquiring it.
