Breach of trust and equitable compensation

Breach of trust is the remedial centre of private express trust law. Earlier weeks established the trust as a proprietary and managerial institution: certainty creates it; constitution transfers or declares it; trustee duties regulate its administration; variation may alter its terms. Week 13 asks what follows when those duties are broken. The answer is not a simple borrowing from tort or contract. Equity has its own remedial grammar, though modern authority has insisted that compensation must remain compensation and not become punishment or insurance.

The starting point is personal liability. A trustee who acts outside the trust terms, misapplies trust property, fails to exercise reasonable care, delegates improperly, acts in conflict, or profits unauthorisedly commits a breach. The beneficiary may seek falsification or surcharge of the account, equitable compensation, restoration of trust property, an account of profits, rescission, injunction, or removal of the trustee. The label matters. A misapplication of trust property is not doctrinally identical to a negligent failure to invest, and a disloyal profit is not remedied by the same measure as an imprudent investment loss.

Equitable compensation for breach of trust is most often examined through Target Holdings Ltd v Redferns and AIB Group (UK) plc v Mark Redler & Co Solicitors. These cases reject an unqualified rule that every unauthorised disbursement must be restored without regard to subsequent events. The court asks what loss to the trust estate was caused by the breach, assessed by reference to the trust obligation breached. Where the breach consists in paying out money contrary to a limited commercial trust, compensation is limited to the loss resulting from that breach, not the whole sum paid out if the intended secured transaction substantially occurred. Yet where trustees dissipate family trust assets or act disloyally, equity remains exacting: strict accountability is not dissolved into common-law negligence.

For Durham purposes, this topic is a bridge between the conceptual foundation of the trust in Week 1 and the practical duties covered in Weeks 10 and 11. In problem questions, begin with the duty and the breach; only then identify the remedy. In essays, resist the crude proposition that Target and AIB simply imported common-law causation. The better view is subtler: equitable compensation is obligation-sensitive. The measure of liability depends on whether the obligation is custodial, managerial, fiduciary, or advisory, and on whether the claim concerns restoration of the trust fund, compensation for loss, or disgorgement of gain.

Historically, trustees were accountable in equity by reference to the account. This matters because breach of trust remedies were not originally conceived as damages. A trustee held property for the beneficiaries and was required to account for it. If an authorised payment appeared in the account, it was allowed. If an unauthorised payment appeared, it could be falsified: the entry was struck out, with the consequence that the trustee remained liable to restore the amount. If the complaint was that the trustee ought to have received more, the beneficiary could surcharge the account: the trustee was charged with the value that should have been obtained. This accounting structure explains much of the modern law’s severity. A trustee is not merely a wrongdoer who has caused loss; he is an office-holder required to justify his stewardship.

The classical cases took a stringent view. Trustees were not liable as insurers, but they were bound to keep within their authority and to act with proper prudence. In Speight v Gaunt the House of Lords recognised that a trustee is not automatically liable for every fraud committed by a broker or agent if he has acted as an ordinary prudent person of business. Conversely, where trustees left control of trust assets in unsafe hands or failed to supervise, cases such as Re Lucking’s Will Trusts and Bartlett v Barclays Bank Trust Co Ltd show that the court will impose liability for negligent administration. The emergence of statutory investment powers and, later, the Trustee Act 2000 did not remove the equitable baseline: powers must be exercised for proper purposes, with appropriate care, and in the interests of the beneficiaries.

For much of the twentieth century, equitable compensation was sometimes described in absolute language. The phrase sometimes associated with Re Dawson in Australia suggested that equity demanded restoration of the trust estate as if the breach had not occurred, without the common-law apparatus of foreseeability or remoteness. That language was powerful where trust property had been misapplied, but dangerous if treated as a universal measure for every equitable wrong. English law’s modern commercial trust cases narrowed the position. Target Holdings concerned solicitors holding mortgage advance money on a bare or limited trust. They released it before the contractual conditions were satisfied, but the security was later completed. The House of Lords held that the lender could not recover the entire advance once the loss actually suffered was only the deficiency caused by the inadequacy of the security transaction.

AIB confirmed this approach in the Supreme Court. The solicitors negligently failed to discharge the whole of a prior mortgage, leaving the lender with a second-ranking security for part of the advance. The court awarded the difference between the position the lender should have had and the position it actually had, not the whole amount advanced. The historical account survived, but as an instrument serving substantive trust obligations, not as a mechanical route to windfall recovery.

The historical lesson is therefore double. First, breach of trust liability is stricter and more property-centred than ordinary civil liability because trustees are accountable fiduciary office-holders. Secondly, the remedy is not detached from causation or from the nature of the trust obligation. Modern English law has not abolished the account; it has disciplined it so that equitable compensation remains compensatory, while preserving stricter remedies for custodial misapplication, unauthorised profit, and disloyal fiduciary conduct.

1. Identify the obligation breached. A trustee’s obligations are not all of the same kind. Custodial obligations require the trustee to hold and preserve trust property. Managerial obligations require prudent investment, supervision, delegation, and distribution. Fiduciary obligations require loyalty: no unauthorised profit, no conflict, and no use of position for personal advantage. Advisory or transactional duties may arise in commercial trust structures, especially where solicitors hold money pending completion. The remedy follows the duty. A breach of loyalty commonly leads to disgorgement of profit; negligent investment leads to compensation for loss; unauthorised disbursement may require restoration unless the loss is shown not to have resulted from the breach.

1. Breach is assessed against the trust instrument, statute, and general equitable duties. A trustee breaches trust by acting outside powers, failing to perform duties, performing powers improperly, acting carelessly where a duty of care applies, preferring personal interests, or failing to account. The trustee’s motives may be relevant to dishonesty, relief, limitation, or exclusion clauses, but honest conduct can still be a breach. A trustee who pays the wrong beneficiary, invests imprudently, fails to diversify, or distributes without proper inquiries may be personally liable though entirely well-intentioned.

1. The primary remedy is restorative in form but compensatory in function. Equity often asks what is required to restore the trust fund to the position it would have occupied had the trustee performed the trust. This is not the same as common-law damages in every respect. Foreseeability is generally not the controlling concept. The trustee’s liability is measured by reference to the obligations undertaken. In a traditional trust, misapplied trust property is normally restored in full. In a limited commercial trust, where the trustee’s role is to hold money until specified conditions are satisfied, the court examines what loss flowed from releasing the money in breach.

The landmark cases show a movement from strict stewardship to obligation-sensitive compensation. Speight v Gaunt established that trustees may use agents in accordance with ordinary prudent practice and are not liable merely because an agent proves fraudulent, provided they have acted prudently. That case remains an antidote to the misconception that trustees are insurers of the fund.

Re Lucking’s Will Trusts and Bartlett v Barclays Bank Trust Co Ltd develop the duty of supervision. In Re Lucking, the trustees’ failure to supervise a company in which the trust held a controlling interest exposed them to liability when the director misappropriated funds. Bartlett is the stronger modern statement: a professional trust corporation holding a controlling shareholding could not remain passive and had to take active steps to monitor the company’s affairs. These cases matter for equitable compensation because breach is often a failure to prevent loss rather than an unauthorised payment made directly by the trustee.

Nestlé v National Westminster Bank plc illustrates both the difficulty of proving causation and the court’s reluctance to judge historic investment performance with hindsight. The beneficiary criticised long-term investment decisions. The Court of Appeal accepted that trustees must keep investments under review but refused to equate poor performance with breach or to calculate compensation by speculative comparison with an ideal portfolio.

Bristol and West Building Society v Mothew is not simply a trusts case, but it is indispensable. Millett LJ clarified that not every equitable duty is fiduciary. A solicitor may be liable in equity for breach of trust or duty of care, but fiduciary duties are those of loyalty. This distinction prevents remedial overreach. Negligence may produce compensation; disloyalty may produce stricter remedies.

Target Holdings and AIB dominate the modern law. In both, solicitors held mortgage funds on trust and released them in breach of instructions. In neither did the court award the entire sum advanced. Instead, the award reflected the loss attributable to the breach. The cases are sometimes criticised for softening trust law to accommodate commercial lending, but they are better understood as insisting that equitable compensation must respond to the purpose of the trust obligation breached.

Armitage v Nurse sits slightly apart. It concerns exemption rather than quantification. Millett LJ held that English law permits clauses excluding liability for negligence, but not fraud, because there remains an irreducible core of trustee obligations enforceable by beneficiaries. The case is controversial, but practically vital. A problem question must always ask whether the trust instrument contains an exemption clause before concluding that an innocent negligent trustee is fully liable.

Together, these authorities produce a disciplined sequence: define the trust obligation, prove breach, identify loss, test equitable causation, consider bars or relief, and choose the correct remedy.
