Constructive trusts: equity’s remedy for wrongs

When courts force a wrongdoer to hold stolen property for its true owner

Education, not legal advice. Trust law changes from country to country and state to state, and the right structure depends on your situation. Anything you sign should be drafted or reviewed by a qualified lawyer where you live.

The lean path

The cheapest, lowest-tax, simplest and most private route the law allows, best first. Each step names the rule it rests on and the condition that keeps it lawful.

  1. Act at once on unauthorised transfers: a consumer who reports one within 60 days of the statement limits liability for later transfers (Regulation E, 12 CFR §1005.6); the bank’s error process costs nothing.
  2. Keep the paper trail free of charge: bank records tracing your money into a specific asset are what a constructive-trust claim rests on, and a written demand to return it should come before any filing.
  3. Against a trustee, use the free steps first: request the trust and reports (UTC §813), try a nonjudicial settlement (§111), then sue within one year of a disclosing report or within five years otherwise (§1005).
  4. Hire a lawyer when the asset is traceable and worth more than the fees: a constructive trust claims the asset itself, which matters most when the wrongdoer is insolvent and a money judgment would go unpaid.

Wonder

  1. What happens if the wrongdoer spends all the money before the court rules?
  2. Does this apply to my partner who secretly bought a house with our joint savings?
  3. How is this different from just suing for damages?

  1. A constructive trust is not created by anyone’s intent. No one signs a document saying, ‘I hereby create this trust.’ Instead, a court imposes it when someone holds property they should not have. The person holding the legal title becomes a trustee in name only. They must hold that asset safe until it can be rightfully transferred to the true owner. This mechanism exists to prevent injustice when standard remedies are insufficient.
  2. In English law, this is often called an ‘institutional’ constructive trust. It arises automatically the moment the wrongful conduct occurs. For example, if a fiduciary makes a secret profit from their position, equity treats that profit as held in trust for the principal immediately. The court does not wait to create the remedy; it recognizes that the duty existed from the start of the breach.
  3. In contrast, many US states treat constructive trusts as ‘remedial.’ Here, the trust is a fiction created by the judge at the time of judgment. It is not an actual ongoing relationship but an order declaring that the plaintiff has equitable title to the specific property. The defendant must transfer ownership and possession to the plaintiff. This view separates the remedy from any continuing fiduciary duties.
  4. Consider a scenario where a bank pays money by mistake to another bank. In *Chase Manhattan Bank v Israel-British Bank*, an English court held the recipient held the funds on constructive trust. However, later in *Westdeutsche Landesbank*, the House of Lords distanced itself from this view for unjust enrichment cases. This highlights that even within England, the application of institutional trusts remains a subject of intense legal controversy and debate.
  5. Courts also use constructive trusts when a shared venture collapses. In the Australian case Muschinski v Dodds (1985), a couple bought land together intending to develop it; she paid far more of the price than he did. When the relationship ended, the High Court of Australia held that it would be unconscionable for either to keep the benefit of the other’s contribution, and imposed a constructive trust so that each first got back what they had put in before the rest was shared.
  6. Because this is an equitable remedy, it depends heavily on jurisdiction and specific facts. In some US states, like those implementing the ‘slayer rule,’ a constructive trust prevents a murderer from inheriting property they killed for. If you believe someone has fraudulently obtained your asset, documenting the exact source of funds and the chain of title is essential before approaching a court.

Key facts

  • A constructive trust is an equitable remedy imposed by a court to benefit a party wrongfully deprived of rights.
  • It arises from conduct (fraud or breach), not from the explicit intent of a settlor.
  • In English law, ‘institutional’ trusts arise automatically upon the wrongful act.
  • In many US states, ‘remedial’ trusts are created by the court at judgment as a fiction.
  • The holder of legal title under this remedy must transfer possession to the true equitable owner.
  • This remedy applies when property is obtained via fraud or a fiduciary’s secret profit.
