Constructive Trusts on Separation:
When Fairness Steps In
Many people assume that once property sits in a trust, any contributions they might have made to it are gone.
That is not always the case. Where a person has invested time, money, or effort into trust property during a relationship, the Courts may be willing to recognise that through a constructive trust.
This article explains when constructive trusts arise, what Courts look at, and how they can help address unfair outcomes at separation.
What is a constructive trust?
A constructive trust is not a typical relationship property claim.
It is not a dispute between partners about how to divide assets. Instead, it is a claim by one partner against the trust itself, based on fairness.
At its heart, a constructive trust asks:
Is it fair for a trust to keep the benefit of someone’s time, money, or effort without giving them anything back?
The Court is not focused on legal ownership. It is focused on whether it would be unfair for the trust to walk away with the benefit of someone’s contributions.

When do constructive trust claims come up?
Constructive trust claims most often arise where:
- property is owned by a trust;
- one partner has made real contributions to that property; and
- those contributions are not otherwise recognised when the relationship ends.
This can include situations where someone:
- paid for renovations or building work;
- helped improve or maintain trust property over time;
- rearranged their life or finances based on an understanding they were building something shared.
What does someone need to show?
In simple terms, a person bringing a constructive trust claim needs to show three things:
- they made real and meaningful contributions to the property;
- they made those contributions believing they would share in the benefit; and
- it would be unfair for the trust to keep those benefits without recognising them.
Knowing that the property was owned by a trust does not automatically defeat a claim. Courts look at what actually happened in practice, not just what the paperwork says.
Constructive trusts in real life
Although the legal language around constructive trusts can sound technical, the cases themselves are very relatable.
Hawke’s Bay Trustee Company v Judd
In this case, Ms Judd lived in a home owned by her partner’s trust. The trust bought the house before the relationship began, and Ms Judd knew the property was trust-owned.
Even so, the Court accepted that it was reasonable for her to expect some recognition of what she had put in.
During the relationship, Ms Judd:
- gave up her own home and her job;
- contributed about $50,000 towards renovations; and
- did extensive work maintaining and improving the property.
In practice, the trust was run almost entirely for her partner’s benefit. The so-called “independent” trustee had very little real involvement, and her partner effectively controlled how the property was used.
The Court said it would be unfair for the trust to keep the benefit of Ms Judd’s contributions without acknowledging them. She was awarded just under 10% of the value of the property.
Chignall v Keane
This case involved a later-in-life relationship where both partners had their own trusts.
Mr Keane’s trust owned land. Ms Chignall contributed $200,000 towards building a house on that land.
The key question was whether that money was:
- a loan that needed to be repaid; or
- a contribution made with the expectation of sharing in the property.
The Court found that if the money had truly been a loan, it would have been properly documented — and it wasn’t. The way the trust usually operated made the absence of paperwork significant.
The Court also accepted that the couple ran their finances on a “what’s mine is mine and what’s yours is yours” basis. That supported Ms Chignall’s belief that such a large contribution would be recognised in some way.
Even though she knew the property was owned by a trust, the Court held that her expectation was reasonable. She was awarded 20% of the value of the property.
What constructive trust cases tell us
Looking across constructive trust cases, some consistent themes emerge:
- Knowing property is owned by a trust does not automatically mean you miss out.
- Courts look closely at what people actually said, did, and understood at the time.
- How a trust operates in real life often matters more than what the trust deed says.
- If a trust freely accepts significant contributions, it may be required to recognise them.
