What is a Constructive Trust?

by | Jun 19, 2025 | Property

Imagine you’ve helped pay the mortgage, invested savings into a deposit, or poured effort into home renovations—but your name isn’t on the property title. That might seem like tough luck, but under Australian law, it doesn’t have to be the end of your story.

Where there is evidence of a common intention that you have a beneficial interest in the property, the courts may impose a constructive trust. This is a tool used to prevent unfair outcomes when one person has made significant contributions to an asset (like a house or business), but doesn’t legally own it. It is an equitable remedy used to prevent unjust enrichment where one party has benefited from another’s contributions, whether financial or non-financial in nature.

. The goal is to ensure fairness, especially when there’s no written agreement but an evident imbalance.

What Courts Look At

To determine whether to impose a constructive trust, courts will evaluate the following essential elements:

Common intention: Was there evidence of an express or implied agreement that both parties would have a beneficial interest in the property?

Contributions: Both financial contributions (including direct monetary inputs) and non-financial contributions (including but not limited to property improvements, domestic services, and care work) that have contributed to the acquisition, maintenance, or improvement of the property. 

Detrimental reliance: Evidence that a party has acted to their detriment in reliance upon representations or conduct indicating a beneficial interest in the property would arise.

Unfairness: Whether denial of the beneficial interest would result in unconscionable detriment to the claimant given the totality of circumstances.

How to Prove a Constructive Trust

To build a successful claim, you’ll need:

Evidence of common intention: Documentary evidence including but not limited to written correspondence, electronic communications, contemporaneous records, and sworn testimony from witnesses with direct knowledge of the parties’ intentions

Documentary evidence of contributions: : Including but not limited to bank statements, payment records, invoices for improvements, contemporaneous records of labour and services rendered, and supporting documentation of non-financial contributions.

Sworn affidavits and witness statements: Detailed sworn testimony from the claimant and independent witnesses with direct knowledge of the relevant facts, circumstances, and intentions of the parties.

Legal representation: Constructive trust claims are complex equitable proceedings requiring comprehensive understanding of property law, trust principles, and relevant precedents. Professional legal advice is essential.

Constructive trusts are just one of several available equitable remedies. Legal advice should be sought to determine the most appropriate remedy for your circumstances, which may include resulting trusts, proprietary estoppel, or express trusts. Each case must be assessed on its individual merits and factual matrix.
