What every couple needs to know about parental contributions and relationship property in New Zealand.
This guide is general information only.
It is not legal advice.
Talk to a lawyer before making decisions about how your deposit contributions are structured.
When a parent contributes money toward a deposit and that contribution is not formally documented, the law treats it as a gift to the relationship.
A gift to the relationship is relationship property.
On separation, it gets divided equally between both partners — regardless of which partner's parents contributed it.
This is not a worst-case scenario.
It is the default outcome for every undocumented parental contribution.
The question is not whether the money was intended as a gift.
It is whether it was documented as a debt — because if it was not, the law treats it as a gift.
Relationship property law generally applies once a couple has been together for three years.
However, there is no hard and fast rule — courts can take into account a range of factors, and the three-year threshold does not cover every situation.
If you are unsure whether your relationship meets the threshold, or if children are involved, get specific legal advice.
Ross and Rachel buy a home together for $600,000:
They split all ongoing costs equally.
Five years later they separate and sell for $1,000,000.
After the outstanding mortgage ($250,000), legal fees ($6,000), and agent fees ($34,000), $710,000 remains.
Without a DOAD, the $150,000 parental contribution is split equally.
Rachel walks away with $355,000 — partly funded by Ross's parents.
With a DOAD, the contribution is repaid to Ross first.
Rachel still receives her fair share of everything else.
A Deed of Acknowledgement of Debt (DOAD) is a legal document both partners sign to confirm that a specific contribution — in this case, from Ross's parents — is a debt rather than a gift.
As a debt, it sits outside the relationship property pool and is repaid before any remaining proceeds are divided.
What a DOAD can cover:
For a DOAD to be enforceable:
A DOAD is not adversarial.
It simply records what the parties have agreed — that a contribution will be treated as a debt if the property is ever sold.
Most couples find it straightforward once they understand what it does.
A DOAD typically records the contribution as a debt owed to the contributing party — Ross's parents in this example.
That means when the property is sold, the funds come back to Ross's parents first.
These examples are straightforward by design.
