Equitable Interest Dispute Lawyers Brisbane

Legal title is where a dispute starts. It is rarely where it ends.
The registered owner of an asset is not always the person who is entitled to it. Property is purchased with someone else’s money. Assets are accumulated during a relationship without any formal agreement about ownership. A promise is made and relied on, but never documented. A trust is imposed by law to prevent someone profiting from their own wrongdoing.

In each of these situations, equity intervenes. It recognises interests that the law of contract and the rules of registered title do not capture. Those interests are real, enforceable, and in many cases worth significant sums. They are also routinely overlooked by parties who do not know they exist, and by lawyers who do not practise in this area.

Boyle Litigation acts for clients asserting and defending equitable interest claims across Queensland and nationally. These are complex, evidence-intensive disputes. They require command of equitable doctrine, careful attention to the facts, and the litigation capability to take a claim to judgment when negotiation fails.

What Is an Equitable Interest?

An equitable interest is a right to property or assets that is recognised by equity rather than by the strict rules of legal ownership. Equity developed as a body of law to address situations where applying the strict legal rules would produce an unjust outcome. Courts of equity recognised that a person could have a beneficial entitlement to property even where they held no legal title.
Equitable interests take a number of forms. Some arise from the conduct of the parties. Some are imposed by law to prevent unjust enrichment. Some arise from a promise made and relied on. All of them can be enforced through the courts, and all of them can be protected by lodging a caveat on the title to the relevant property while the dispute is pending.
The most significant and commonly litigated equitable interests are constructive trusts, resulting trusts, proprietary estoppel, and claims for unjust enrichment. Each operates differently and arises in different factual circumstances. What they have in common is that they give a claimant rights over property that go beyond what the strict legal title says.

Re-Entry, Lockout and Recovery of Possession

Constructive Trust
Imposed by a court where it would be unconscionable to allow the legal owner to retain the benefit of property to the exclusion of the claimant. Arises from common intention, contribution, or unconscionable conduct.
Resulting Trust
Arises where property is transferred but the transferor did not intend to benefit the transferee, or where a purchase is made in another’s name. The property is held on trust for the person who provided the funds.
Proprietary Estoppel
Arises where a person is encouraged to believe they have or will have rights over property, acts to their detriment in reliance on that belief, and it would be unconscionable to deny the interest claimed.
Equitable Lien
A security interest over property arising by operation of equity to secure a debt or obligation. Arises in a number of commercial contexts, including where a purchase price has been paid but title not yet transferred.
Vendor’s Lien
Where a vendor transfers property but the purchase price remains unpaid, equity recognises a lien over the property to secure the outstanding amount, even without a registered mortgage.
Unjust Enrichment
A personal claim requiring the defendant to restore a benefit they have received at the claimant’s expense in circumstances that the law regards as unjust. May give rise to a proprietary remedy in some circumstances.

Constructive Trusts

A constructive trust is a trust imposed by a court of equity where it would be unconscionable to allow the legal owner to retain the full benefit of property to the exclusion of another person who has a legitimate claim to it. It is not a matter of agreement. It is imposed by operation of law when the relevant circumstances are established.
Common Intention Constructive Trusts
The most frequently litigated form of constructive trust arises where two or more people have a common intention that property will be shared in a way that is not reflected in the legal title, and one of them acts to their detriment in reliance on that intention.
Common intention can be established expressly, through conversations and representations made at the time of acquisition or during the course of the relationship. It can also be inferred from the conduct of the parties, including financial contributions to the purchase price, mortgage repayments, and improvements to the property.
These claims arise most commonly in the context of:

Institutional and Remedial Constructive Trusts

Australian courts recognise two conceptual approaches to the constructive trust. The institutional constructive trust arises automatically when the relevant facts are established: the trust exists from the moment the facts giving rise to it occurred, not from the date of the court order. The remedial constructive trust, by contrast, is a remedy the court imposes in its discretion to prevent unjust enrichment or unconscionable conduct, with the court having flexibility in how it is crafted.
The distinction has practical significance. An institutional constructive trust, once established, takes priority over third parties who later acquire an interest in the property with notice of the trust. A remedial constructive trust is more flexible but less certain in its priority effects. We advise on which form of constructive trust applies to the specific facts and what consequences flow for the client’s position.

Constructive Trusts Arising from Unconscionable Conduct

Where a person obtains property through fraud, breach of fiduciary duty, or other unconscionable conduct, a court will impose a constructive trust over the property in favour of the person who has been wronged. This is equity’s response to wrongdoing that produces a proprietary benefit: the wrongdoer is not permitted to retain the property, and a trust is imposed to restore it.
This form of constructive trust arises in director disputes involving misappropriation of company assets, estate disputes involving undue influence or fraud, and commercial transactions where one party has obtained property through dishonest conduct.

Resulting Trusts

A resulting trust arises where the legal ownership of property does not reflect the beneficial entitlement of the person who provided the consideration for its acquisition. The trust results back to the person who paid for the property, reflecting the presumed intention that the transferee was not intended to take beneficially.

Purchase Money Resulting Trusts

Where a person provides all or part of the purchase price for property that is conveyed into another’s name, a resulting trust arises in proportion to the contribution. The person on title holds the property, or a share of it, on trust for the person who paid.
This presumption can be rebutted by evidence that the payment was intended as a gift or loan rather than a contribution to beneficial ownership. The nature of the relationship between the parties affects the strength of the presumption: the presumption of advancement, which historically applied to transfers from parent to child and from husband to wife, can rebut the resulting trust presumption in some circumstances, though its scope has been narrowed by modern authority.

Failure of Purpose Resulting Trusts

A resulting trust also arises where property is transferred for a specific purpose that subsequently fails. The property does not belong to the transferee; it results back to the transferor because the intended purpose of the transfer has not been achieved. This form of resulting trust is relevant in commercial contexts where funds are advanced for a specific transaction that does not proceed.

Proprietary Estoppel

Proprietary estoppel is an equitable doctrine that prevents a person from asserting their strict legal rights over property where doing so would be unconscionable in light of representations they have made and another person’s reliance on those representations.
The classic elements of a proprietary estoppel claim are:

When Proprietary Estoppel Arises

Proprietary estoppel claims most commonly arise in the following situations:
Factual context
Family farming and business arrangements
Informal cohabitation arrangements
Long-term commercial relationships
Testamentary promises
Development and improvement contributions
A family member is promised the farm or family business in exchange for years of work and contribution, but the promise is not honoured in the estate or during the owner’s lifetime.
A person is encouraged to move into a property or contribute to its improvement on the basis of assurances about future ownership, but no formal documentation is created.
A business partner, employee or contractor is promised an equity interest or ownership stake in return for contributions made over time, but the promise is never formalised.
A person changes their position, including by foregoing other opportunities or career prospects, in reliance on a promise that they will inherit property, but the estate does not reflect that promise.
A person funds or undertakes substantial improvements to another’s property on the basis of assurances about their future interest in it, without obtaining formal documentation.

What the Court Can Order

Where a proprietary estoppel is established, the court has a broad discretion to fashion a remedy that satisfies the equity. The remedy is calibrated to the minimum necessary to do justice between the parties, which may be less than the full interest promised. Possible remedies include:
The flexibility of the remedy is one of proprietary estoppel’s key features. It allows a court to respond proportionately to the specific circumstances rather than applying a rigid rule.

Comparing the Key Equitable Claims

Choosing the right equitable claim, or combination of claims, depends on the specific facts. The following comparison identifies the key differences between the principal claims.
Constructive trust
Unconscionability: common intention, contribution, or wrongdoing
Common intention + detriment, or unconscionable conduct producing a proprietary benefit
Beneficial ownership of property or a share of it; account of profits
Resulting trust
Payment of purchase price into another’s name without gift intention
Contribution to purchase price; absence of gift intention
Proportionate beneficial interest in the property
Proprietary estoppel
Assurance + reliance + detriment + unconscionability in resiling
Clear assurance, reasonable reliance, detriment, unconscionability
Flexible: transfer, licence, charge, or monetary compensation
Equitable lien
Payment of purchase price without receipt of title; unpaid vendor
Payment made; obligation to transfer unfulfilled
Security interest over the property; right to apply for sale
Unjust enrichment
Enrichment at claimant’s expense in unjust circumstances
Enrichment, at claimant’s expense, unjust factor, no juristic reason
Personal restitutionary award; proprietary remedy in some cases

Evidence: The Foundation of Every Equitable Claim

Equitable interest claims are won or lost on evidence. The legal framework is clear. What courts are doing in these cases is making findings of fact about what was said, what was agreed, what was contributed, and what was relied upon, often in the absence of any written record.
The evidence that matters most in these claims includes:
We advise on the evidence required to establish or defend an equitable interest claim from the outset, and we build the evidentiary foundation systematically before proceedings are commenced. Evidence is harder to gather as time passes. Acting early protects the client’s position.
The absence of a written agreement does not mean the absence of a claim. Many of the strongest equitable interest claims arise precisely because the parties trusted each other enough not to document their arrangements.

Protecting Your Position: Caveats and Injunctions

Lodging a Caveat

Where a person has a caveatable interest in property, they can lodge a caveat on the Queensland title register to prevent any dealing with the property, including sale, mortgage, or transfer, until the caveat is removed or lapses. A constructive trust, resulting trust, or proprietary estoppel claim that gives rise to an interest in land will, in most cases, support a caveat.
A caveat is a critical protective step. Without it, the property can be sold to a third-party purchaser who may take free of the equitable interest. Once the property is gone, the claim becomes a personal claim against the defendant rather than a proprietary claim over the asset, which fundamentally changes the recovery position.
Lodging a caveat without a proper legal basis exposes the caveator to a compensation claim. We assess whether the interest is caveatable and advise on the correct basis for the caveat before it is lodged.

Urgent Injunctions

Where a caveat is not available or where the conduct of the other party requires more immediate restraint, an urgent injunction can be obtained from the Supreme Court of Queensland. An injunction can restrain a threatened sale, prevent dissipation of the proceeds of a completed sale, or preserve the status quo while the equitable interest claim is litigated.
The application for an urgent injunction requires the applicant to demonstrate a serious question to be tried, that the balance of convenience favours the injunction, and that damages would not be an adequate remedy. A well-prepared equitable interest claim, supported by clear evidence, is the best foundation for a successful injunction application.

How We Approach Equitable Interest Claims

Equitable claims are among the most technically demanding disputes in commercial litigation. They require precise analysis of the factual record, command of the applicable doctrine, and the judgment to identify which claim or combination of claims gives the client the strongest position.
Our approach:
Our principal holds QLS Specialist Accreditation in Commercial Litigation. Equitable interest claims are not routine litigation. They require lawyers who understand equity as a living body of doctrine, not a historical curiosity. We bring that depth.

When You Need to Act Immediately

Delay in an equitable interest claim can be fatal. The property may be sold. The proceeds may be dissipated. Evidence may be destroyed. The doctrine of laches, which can bar an equitable claim where the claimant has delayed unreasonably, adds a further reason to act promptly.

Frequently Asked Questions

What is an equitable interest in property?
An equitable interest is a right to property that is recognised by equity rather than by the rules of registered title. It arises in a range of circumstances, including where a person has contributed to the purchase of property held in another’s name, where a person has been promised an interest in property and has acted to their detriment in reliance on that promise, or where a person obtains property through unconscionable conduct. An equitable interest is enforceable through the courts and can be protected by lodging a caveat on the title to the property while the dispute is pending.
Both are equitable trusts imposed by operation of law rather than by express agreement, but they arise in different circumstances. A resulting trust arises where property is transferred into another’s name without any intention to benefit the transferee, typically where the transferor has paid all or part of the purchase price. The trust results back to the person who provided the funds in proportion to their contribution. A constructive trust is broader and more flexible. It is imposed where it would be unconscionable to allow the legal owner to retain the full benefit of the property to the exclusion of the claimant. It can arise from common intention, contribution, breach of fiduciary duty, or other unconscionable conduct. In practice, both types of trust are often pleaded in the alternative.
Mortgage contributions can support a constructive trust or resulting trust claim, but they do not automatically do so. The court will examine the totality of the arrangements between the parties, including any common intention about how the property was to be held, whether the contributions were treated as gifts or loans, and what the parties’ conduct reveals about their actual agreement. Financial contributions to mortgage repayments, particularly over a sustained period, are strong evidence of a common intention that the contributing party has a beneficial interest in the property. The strength of the claim depends on the specific facts and what other evidence is available.
Proprietary estoppel and constructive trusts are related but distinct equitable doctrines. Proprietary estoppel focuses on a specific assurance or representation made by the property owner, the claimant’s reliance on that assurance, and the detriment suffered as a result. The claim is that it would be unconscionable for the property owner to resile from the representation. A constructive trust, by contrast, does not necessarily require a specific representation: it can arise from a course of conduct, common intention, or from wrongdoing that produces a proprietary benefit. In practice, many equitable interest claims plead both doctrines in the alternative, because the factual circumstances that give rise to one frequently also support the other.
This is a classic proprietary estoppel scenario, and it is one of the most frequently litigated equitable claims in Australia. Where a family member has been promised an interest in property, has worked on the farm or business in reliance on that promise over an extended period, and has not been compensated for their contribution, they may have a strong equitable claim. The strength of the claim depends on how clearly the promise was made, how the claimant’s conduct demonstrates reliance on it, and what detriment they suffered by acting on the promise rather than pursuing other opportunities. We advise on this type of claim regularly.
Yes, in most cases. A person who has a caveatable interest in land, which includes a beneficial interest arising under a constructive trust, resulting trust, or proprietary estoppel, can lodge a caveat on the Queensland title register to prevent any dealing with the property until the caveat is removed or the underlying claim is resolved. Lodging a caveat without a proper legal basis exposes the caveator to a compensation claim, so it is important to obtain advice before lodging. We assess the caveatable interest and advise on the correct basis for the caveat to maximise protection and minimise exposure.
Yes. The equitable doctrine of laches can bar a claim where the claimant has delayed unreasonably in bringing it, and that delay has prejudiced the defendant. The doctrine reflects equity’s expectation that claimants act with reasonable promptness once they become aware of their rights. Statutory limitation periods also apply to some equitable claims, depending on the nature of the claim and the jurisdiction. In practice, the most important reason to act promptly is not limitation: it is evidence. Documents are lost, witnesses’ recollections fade, and property may be sold or encumbered in the meantime. Acting early consistently produces better outcomes.
Yes. We act for registered proprietors, legal owners, and other parties who are defending equitable interest claims asserted against them. Equitable claims can be overstated, legally misconceived, or based on a mischaracterisation of the relevant facts. A registered proprietor facing an equitable interest claim has legitimate defences available, including challenging the factual basis of the claim, asserting that contributions were intended as gifts or loans rather than equity, and relying on the equitable defences of laches, acquiescence, and change of position. We advise on the strength of the claim being asserted and develop a defence strategy calibrated to the specific facts.
