Equity and Trust – Equitable Tracing
Introduction
Equitable tracing is a process used by the courts to identify and follow trust property after it has been wrongfully transferred, exchanged, or converted into another form. The purpose of tracing is to allow beneficiaries to recover property or substitute assets after a breach of trust or fiduciary wrongdoing.
Tracing does not itself create rights; rather, it identifies where the claimant’s existing equitable proprietary interest has moved. Once the property or its substitute is identified, the claimant may then seek proprietary remedies such as:
Basic Example of Equitable Tracing
Assume Daniel is trustee of the Carter Family Trust.
Daniel improperly removes:
£100,000
from the trust fund and uses the money to purchase a luxury car for himself.
This constitutes:
✅ a breach of trust.
The beneficiaries wish to recover the loss caused to the trust.
Equity allows the beneficiaries to:
✅ trace the trust money into the car.
The beneficiaries may then ask the court to:
Why Equitable Tracing Is Necessary
The beneficiaries are not legal owners of the trust property. Legal title is held by the trustee.
As a result:
❌ common law tracing is usually unavailable.
The beneficiaries must therefore rely upon:
✅ equitable tracing.
Equity is more flexible than common law tracing and allows tracing through:
Requirements for Equitable Tracing
Before tracing in equity is possible, two requirements must usually be satisfied.
Fiduciary Relationship
First, there must be:
✅ a fiduciary relationship
between the claimant and the person who initially held the legal title to the property.
Meaning of Fiduciary Relationship
A fiduciary is someone entrusted to act in the interests of another.
Examples include:
Example
In the trust example above:
Equitable Proprietary Interest
Second, the claimant must possess:
✅ an equitable proprietary interest
in the property being traced.
This means the claimant must have beneficial ownership recognised in equity.
Example
The beneficiaries possess an equitable interest in the trust fund because they are beneficial owners under the trust.
The interest may arise under:
Re Diplock
The leading authority is Re Diplock.
Facts of Re Diplock
Executors of Caleb Diplock’s estate wrongly distributed approximately:
£250,000
to various charities under a clause later found invalid.
The money should properly have passed to:
✅ the next of kin.
The next of kin therefore sought recovery.
Importance of the Case
The court confirmed the two prerequisites for equitable tracing.
Fiduciary Requirement
The executors were fiduciaries because executors owe fiduciary duties when administering estates.
Importantly, the charities themselves did not need to be fiduciaries.
The relevant fiduciary relationship concerned:
✅ the original holders of the property.
Equitable Interest Requirement
The next of kin possessed equitable proprietary interests as the true beneficiaries of the estate.
They were therefore entitled to trace the misapplied property.
Tracing Into Third Parties
Equitable tracing may continue even where trust property passes into the hands of third parties.
However, tracing may fail if the property reaches:
✅ a bona fide purchaser for value without notice.
Such purchasers are protected in equity.
Criticism of the Fiduciary Requirement
The requirement for an initial fiduciary relationship has been criticised.
In Foskett v McKeown, Lord Millett suggested, obiter, that there was:
no logical justification
for insisting upon a fiduciary relationship as a strict prerequisite for equitable tracing.
Lord Millett’s View
Lord Millett argued that tracing is fundamentally concerned with:
✅ proprietary interests,
rather than fiduciary status.
Modern Position
Although criticism remains, courts generally continue formally to require:
Tracing and Substitute Property
One of equity’s most powerful features is that tracing permits claimants to follow value into substitute assets.
Example
Suppose Daniel uses trust money to purchase:
✅ the substitute asset.
The beneficiaries may then seek:
Mixed and Unmixed Funds
The rules governing tracing differ depending upon whether funds remain:
✅ unmixed,
or
✅ mixed.
Unmixed Funds
Tracing is relatively straightforward because the property remains identifiable.
Mixed Funds
Tracing becomes more complicated where trust money is mixed with:
Why Equitable Tracing Matters
Equitable tracing provides beneficiaries with powerful proprietary protection because it allows them to:
Key SQE Principles
To trace in equity, the claimant usually must show:
✅ a fiduciary relationship;
and
✅ an equitable proprietary interest.
Equitable tracing allows claimants to follow property into:
Conclusion
Equitable tracing is a central doctrine within equity and trust law that enables beneficiaries to identify and recover trust property after breaches of trust and fiduciary wrongdoing. By allowing claimants to follow property into substitute assets and mixed funds, equity preserves proprietary rights even where trust property has changed form. Although tracing traditionally requires both a fiduciary relationship and an equitable proprietary interest, modern judicial commentary has questioned whether the fiduciary requirement remains conceptually necessary. Nevertheless, equitable tracing continues to provide one of the most powerful mechanisms for protecting beneficiaries and recovering misapplied trust property.

Introduction
Equitable tracing is a process used by the courts to identify and follow trust property after it has been wrongfully transferred, exchanged, or converted into another form. The purpose of tracing is to allow beneficiaries to recover property or substitute assets after a breach of trust or fiduciary wrongdoing.
Tracing does not itself create rights; rather, it identifies where the claimant’s existing equitable proprietary interest has moved. Once the property or its substitute is identified, the claimant may then seek proprietary remedies such as:
- recovery of the property;
- a constructive trust;
- an equitable lien;
- or a charge over substitute assets.
Basic Example of Equitable Tracing
Assume Daniel is trustee of the Carter Family Trust.
Daniel improperly removes:
£100,000
from the trust fund and uses the money to purchase a luxury car for himself.
This constitutes:
✅ a breach of trust.
The beneficiaries wish to recover the loss caused to the trust.
Equity allows the beneficiaries to:
✅ trace the trust money into the car.
The beneficiaries may then ask the court to:
- order sale of the car;
- return the proceeds to the trust;
- or impose proprietary remedies over the vehicle.
- the trust money;
into - the substitute asset (the car).
Why Equitable Tracing Is Necessary
The beneficiaries are not legal owners of the trust property. Legal title is held by the trustee.
As a result:
❌ common law tracing is usually unavailable.
The beneficiaries must therefore rely upon:
✅ equitable tracing.
Equity is more flexible than common law tracing and allows tracing through:
- mixed funds;
- substitute assets;
- and complex financial transactions.
Requirements for Equitable Tracing
Before tracing in equity is possible, two requirements must usually be satisfied.
Fiduciary Relationship
First, there must be:
✅ a fiduciary relationship
between the claimant and the person who initially held the legal title to the property.
Meaning of Fiduciary Relationship
A fiduciary is someone entrusted to act in the interests of another.
Examples include:
- trustees;
- executors;
- solicitors;
- company directors;
- agents;
- and partners.
Example
In the trust example above:
- Daniel is trustee;
- therefore Daniel is a fiduciary.
Equitable Proprietary Interest
Second, the claimant must possess:
✅ an equitable proprietary interest
in the property being traced.
This means the claimant must have beneficial ownership recognised in equity.
Example
The beneficiaries possess an equitable interest in the trust fund because they are beneficial owners under the trust.
The interest may arise under:
- an express trust;
- a resulting trust;
- or a constructive trust.
Re Diplock
The leading authority is Re Diplock.
Facts of Re Diplock
Executors of Caleb Diplock’s estate wrongly distributed approximately:
£250,000
to various charities under a clause later found invalid.

The next of kin therefore sought recovery.

no logical justification
for insisting upon a fiduciary relationship as a strict prerequisite for equitable tracing.
Lord Millett’s View
Lord Millett argued that tracing is fundamentally concerned with:
- identifying property rights;
- not fiduciary wrongdoing itself.
✅ proprietary interests,
rather than fiduciary status.
Modern Position
Although criticism remains, courts generally continue formally to require:
- an initial fiduciary relationship;
and - an equitable proprietary interest.
Tracing and Substitute Property
One of equity’s most powerful features is that tracing permits claimants to follow value into substitute assets.
Example
Suppose Daniel uses trust money to purchase:
- shares;
- jewellery;
- property;
- or cryptocurrency.
✅ the substitute asset.
The beneficiaries may then seek:
- ownership of the asset;
- a proportional share;
- or an equitable lien.
Mixed and Unmixed Funds
The rules governing tracing differ depending upon whether funds remain:
✅ unmixed,
or
✅ mixed.
Unmixed Funds
Tracing is relatively straightforward because the property remains identifiable.
Mixed Funds
Tracing becomes more complicated where trust money is mixed with:
- trustee money;
- other trust funds;
- or third-party funds.
- Re Hallett;
- Re Oatway;
- Roscoe v Winder;
- and Clayton’s Case.
Why Equitable Tracing Matters
Equitable tracing provides beneficiaries with powerful proprietary protection because it allows them to:
- recover substitute assets;
- obtain priority in insolvency;
- benefit from increases in value;
- and preserve proprietary rights after wrongdoing.
Key SQE Principles
To trace in equity, the claimant usually must show:
✅ a fiduciary relationship;
and
✅ an equitable proprietary interest.
Equitable tracing allows claimants to follow property into:
- substitute assets;
- mixed funds;
- and third-party hands.
Conclusion
Equitable tracing is a central doctrine within equity and trust law that enables beneficiaries to identify and recover trust property after breaches of trust and fiduciary wrongdoing. By allowing claimants to follow property into substitute assets and mixed funds, equity preserves proprietary rights even where trust property has changed form. Although tracing traditionally requires both a fiduciary relationship and an equitable proprietary interest, modern judicial commentary has questioned whether the fiduciary requirement remains conceptually necessary. Nevertheless, equitable tracing continues to provide one of the most powerful mechanisms for protecting beneficiaries and recovering misapplied trust property.
