Lowest Intermediate Balance Rule in Equitable Tracing

When trust money is mixed into a bank account, the lowest intermediate balance rule caps what equitable tracing can recover from it.

The lowest intermediate balance rule caps a claim to trust money remaining in a mixed bank account at its lowest balance after the trust deposit. Later salary or trading receipts ordinarily cannot rebuild that claim. A current balance can therefore overstate the money you can recover from that account.

What the Lowest Intermediate Balance Rule Does

The rule limits the surviving account claim to the smaller of the trust contribution and the lowest intervening balance. It applies when the claimant identifies trust money within an account containing other money.

In James Roscoe (Bolton) Ltd v Winder [1915] 1 Ch 62, later unrelated deposits did not replace trust money already spent. Evidence that a payment was intended to restore the trust fund can change the result. The Privy Council discusses the decision in Brazil v Durant, paragraph 19.

This cap concerns the money left in the account. A withdrawal that purchased an identifiable asset requires a separate tracing analysis into that asset. The account’s low point does not automatically cap every proprietary claim arising from the original misapplication.

Equitable Tracing Into Mixed Funds

Equitable tracing identifies value in substitute property, including money mixed with another person’s funds. Commingled funds are money belonging to different people held in one account. Mixing alone does not destroy the claimant’s interest. A mixed fund holds value from different beneficial sources together. Preserve the amount and timing of each contribution alongside the full balance history before allocating withdrawals.

Foskett v McKeown [2001] 1 AC 102 distinguishes tracing the substitution from deciding the remedy. First identify the claimant’s property interest and the transactions through which it passes. Then determine the claim available against the surviving property.

Australian cases historically required a fiduciary relationship, such as trustee and beneficiary, to supply the equitable foundation. That requirement is not universal. In RnD Funding Pty Ltd v Roncane Pty Ltd [2023] FCAFC 28, the Full Federal Court accepted a sufficient equitable property interest. An equitable charge or mortgage can supply that foundation without an antecedent fiduciary duty. The NSW Supreme Court’s case summary explains the decision at paragraphs 45 and 113.

Re Hallett’s Estate (1880) 13 Ch D 696 presumes that a trustee withdrawing from a mixed account spends their own money first. If the trustee has $20,000 and the trust has $80,000, a $15,000 withdrawal ordinarily leaves the trust’s $80,000 intact.

Re Oatway [1903] 2 Ch 356 prevents the trustee using that presumption to keep a surviving investment while treating later spending as the trust’s loss. The claimant can trace into the purchased asset when the account’s remaining money was dissipated. Justice Edelman explains the investment and mixed-fund distinction.

These rules decide what can be claimed from a completed asset trace. They do not let the claimant recover the same contribution twice.

Competing Claimants and Pro Rata Sharing

Between innocent contributors, the court must decide whose money survives and how a shortfall is shared. The presumption against a wrongdoer does not give one innocent victim priority over another.

Clayton’s case, Devaynes v Noble (1816) 1 Mer 572, uses first in, first out. Earlier deposits are treated as funding earlier withdrawals. Applied mechanically between victims, it can exhaust an early contributor’s claim while preserving a later contributor’s money. It does not let a trustee allocate trust money to losses for their own benefit.

In Re French Caledonia Travel Service Pty Ltd (2003) 59 NSWLR 361, Campbell J rejected Clayton’s rule for the pooled trust money. He permitted proportionate distribution where the evidence supplied no reason to distinguish classes of claimants. Further account analysis risked consuming the small fund in costs.

That judgment does not abolish the lowest intermediate balance rule between victims. Earlier contributors can have different rights if the account emptied before later deposits. Rateable sharing depends on the fund and the evidence, not simply the existence of several claimants.

Applying the Rule to a Bank Statement

Rebuild the running balance after every transaction to find the low point. A closing statement balance alone cannot establish it.

This invented example uses Australian dollars. Assume a single trust deposit and ordinary spending. Every debit is dissipated, and the salary is unrelated to restoring trust funds.

EventCreditDebitAccount balanceTrust money remaining under the rule
Opening balance: director’s own money$20,000$0$20,000$0
Trust money deposited$400,000$0$420,000$400,000
First withdrawal$0$50,000$370,000$370,000
Further spending$0$200,000$170,000$170,000
Final spending before salary$0$158,000$12,000$12,000
Director’s salary received$30,000$0$42,000$12,000

The first withdrawal uses the director’s $20,000 and then $30,000 of trust money under the Hallett presumption. Later debits reduce the surviving trust money to $12,000. Salary raises the account balance to $42,000 but leaves the account claim capped at $12,000.

Incorrect calculation: claiming $42,000 solely because that is the current balance. The unrelated salary does not restore dissipated trust money.

Correct calculation: identifying the $12,000 low point and assessing any separately traced assets or personal claims alongside it.

Include every statement page from the trust deposit to the point of assessment. One missing month can conceal a lower balance. Reconcile each period’s opening balance, transactions and closing balance before relying on the calculated minimum.

Where the Trace Stops

An ordinary proprietary trace stops where spending leaves no identifiable substitute property. Living costs and payments extinguishing ordinary debts can dissipate the money. An account reaching zero ordinarily eliminates the surviving claim to that account. Paying into an overdraft reduces a debt instead of creating a positive bank balance.

A personal claim against the wrongdoer can remain even though that proprietary trace ends. Payment of secured debt can also raise subrogation issues, so a debt payment does not settle every possible remedy.

Backwards tracing concerns an asset acquired before the misapplied money arrives, often using temporary borrowing. In Federal Republic of Brazil v Durant International Corporation [2015] UKPC 35, the Privy Council allowed it where the transactions formed a coordinated scheme. Paragraphs 33 to 40 require a connection between the acquisition and the later misuse. An unrelated later deposit is insufficient.

In Elite Realty Development Pty Ltd v Sadek [2023] NSWCA 165, paragraphs 78 to 79, the Court of Appeal declined to determine backwards tracing. The issue had not been litigated at trial. Its treatment shows why the claim needs a pleaded connection between the earlier purchase and later misuse, supported by evidence.

Backwards tracing remains unsettled in Australia. Durant supplies a persuasive approach from a Jersey appeal, rather than a binding Australian appellate rule. A claim based on it needs evidence of the coordinated transaction. A matching amount or the fact that a later payment cleared borrowing does not establish that connection by itself.

Why the Rule Matters in Insolvency and Fraud Claims

A proven proprietary claim can place identifiable property beyond the pool available to unsecured creditors in bankruptcy or liquidation. That is the practical difference between recovering surviving trust property and proving for a debt. Justice Derrington discusses tracing and insolvency priority.

A proprietary claim asserts rights to identified value or its substitute. Personal compensation instead seeks payment from the defendant for an established liability. Proof that money moved between accounts supplies transaction evidence, but does not by itself establish either claim.

The claimant still needs to establish the interest and the remedy. Existing competing rights and proper costs of administering trust property can affect the amount ultimately distributed.

The account calculation informs a breach of trust claim, while a trace into a recipient’s hands supplies evidence for a knowing receipt claim. Receipt and its amount do not alone establish the recipient’s required knowledge. An asset bought with the money can support a claim to property through a constructive trust or an equitable lien.

For a freezing order, distinguish the surviving proprietary amount from the wider personal claim being preserved. The $12,000 account cap in the example does not automatically limit a properly supported personal claim to $12,000. Put the low-point calculation beside the claim’s legal basis so the relief sought reflects the surviving property and the separate loss.
