How is relationship property divided in New Zealand?
When a relationship ends in New Zealand, the Property (Relationships) Act 1976 provides that relationship property is divided equally between partners. This 50/50 rule applies to married couples, civil union partners, and de facto partners who have lived together for three or more years. The family home, household chattels, and any property acquired during the relationship are classified as relationship property — regardless of who paid for them or whose name is on the title.
That’s the starting point. In practice, most disputes aren’t about the rule itself — they’re about what counts as relationship property, how to deal with trusts, whether an inheritance has lost its separate status, and what happens when one partner gave up a career for the family. These are the issues we deal with every day.
What counts as relationship property?
The Property (Relationships) Act 1976 defines two categories: relationship property (divided equally) and separate property (kept by the owner). Understanding which assets fall into which category is where most disputes begin.
Relationship property includes:
- The family home (section 8, Property (Relationships) Act 1976) — regardless of who owned it before the relationship, once a home becomes the family home it is relationship property
- Household chattels — furniture, vehicles, appliances, and other items used by the family
- Property acquired by either partner during the relationship
- The proportion of KiwiSaver and superannuation that accumulated during the relationship
- Income earned by either partner during the relationship
- Any property acquired from relationship property (e.g., an investment purchased with joint savings)
Separate property includes:
- Property owned by one partner before the relationship began
- Inheritances received by one partner
- Gifts from third parties intended for one partner only
- Property acquired from separate property (provided it hasn’t been intermingled)
The critical issue in many disputes is intermingling — when separate property has been mixed with relationship property or used to improve shared assets. For example, if one partner uses an inheritance to renovate the family home, that inheritance may lose its separate property status entirely. Classification disputes are common, and the outcome often turns on exactly how and when assets were mixed.
What happens to the family home?
The family home is almost always classified as relationship property under section 8 of the Act — even if one partner owned it before the relationship. This surprises many people, particularly where one partner purchased the home independently and the other moved in later.
In practice, the family home is usually the largest single asset in a relationship property pool. The options are typically: one partner buys the other out (offsetting against other assets), or the property is sold and the proceeds divided. Where children are involved and one parent has primary care, the court may defer the sale of the home under section 26A to provide stability for the children — but the underlying entitlement remains 50/50.
In Auckland, where median house prices exceed $1 million, the financial stakes in relationship property division are significant. Our Auckland-based senior lawyer Gabrielle Thompson works exclusively on relationship property matters and understands the practical complexities of Auckland’s property market — including situations where the family home is the only substantial asset and one partner cannot afford to buy the other out.
How do trusts affect relationship property?
Family trusts are commonly used in New Zealand to protect assets, but a trust does not automatically remove property from the relationship property pool. The Family Proceedings Act 1980 (section 182) gives the Family Court power to vary or resettle a trust where one partner has used it to defeat the other’s relationship property claim.
The courts look at whether the trust was set up or used to protect assets from division. If one partner transferred the family home or other significant assets into a trust during the relationship, the court can — and regularly does — order that those assets be treated as relationship property.
We have particular expertise in trust-related disputes. These are among the most complex relationship property matters because they involve both relationship property law and trust law, and the outcome often depends on the specific timing, purpose, and structure of the trust.
What is an income disparity claim?
When one partner has sacrificed career progression to care for children or manage the household, the Property (Relationships) Act 1976 (sections 15 and 15A) allows the court to award compensation for the economic disparity caused by the division of roles during the relationship.
The Supreme Court in Scott v Williams [2017] NZSC 185 set down a framework for assessing income disparity claims. The court looks at:
- The respective incomes and earning capacity of each partner after separation
- Whether there is a causal link between the disparity in income and the roles assumed during the relationship
- The likely duration of the disparity
- The extent to which the higher-earning partner’s career was enhanced by the other partner’s domestic contribution
In practice, income disparity claims add significant value to a settlement for the partner who gave up earning capacity. However, they are factually complex and require careful evidence about earnings history, career trajectory, and the domestic arrangements during the relationship. These claims are one of our areas of particular strength.
“Income disparity claims are often undervalued or missed entirely when people try to divide property without legal advice. The difference between a straightforward 50/50 split and a properly assessed claim that accounts for career sacrifice can be substantial — often tens of thousands of dollars.”

Contracting out agreements (prenups)
A contracting out agreement under section 21 of the Property (Relationships) Act 1976 allows partners to agree on how their property will be divided, overriding the default 50/50 split. Both parties must receive independent legal advice for the agreement to be enforceable — the Act requires this, and an agreement signed without independent advice can be set aside by the Family Court.
Contracting out agreements are most commonly used when:
- One partner brings significant pre-relationship assets or property into the relationship
- One partner has received or expects to receive a substantial inheritance
- One partner owns a business or holds shares in a family company
- Partners entering a second relationship want to protect assets for children from a previous relationship
We act for people entering new relationships who want a contracting out agreement in place, and for those whose existing agreements need updating as circumstances change.
Reaching agreement vs going to court
We always encourage private agreement over court proceedings. A negotiated settlement preserves relationships (particularly important where children are involved), is faster, costs less, and gives both parties more control over the outcome.
For a relationship property agreement to be enforceable under the Act, it must be in writing and both parties must have received independent legal advice. We guide clients through this process, from initial disclosure of assets through to signing the agreement.
If agreement cannot be reached, either party can apply to the Family Court for a division of relationship property. We have significant experience in Family Court advocacy and litigation — but we treat court as a last resort, not a first step.

Frequently Asked Questions
What is the 3-year rule for relationship property in NZ?
De facto couples must have lived together for at least three years before the Property (Relationships) Act 1976 applies in full. Below three years, the court has limited discretion to divide property and will only do so if there has been a substantial contribution to the relationship or a child of the relationship exists. After three years, the same equal-sharing rules apply as for married and civil union couples.
Can I protect my inheritance from a relationship property claim?
An inheritance is initially classified as separate property under the Property (Relationships) Act 1976. However, if the inheritance is mixed with relationship property — for example, deposited into a joint account or used to improve the family home — it may lose its separate status. The safest way to protect an inheritance is to keep it entirely separate and, ideally, to have a contracting out agreement in place.
How is a family business divided in a relationship property split?
A business or shares acquired during the relationship are generally relationship property. The business will need to be valued (typically by an independent valuer), and the value divided between the partners. This doesn’t necessarily mean the business is sold — often one partner retains the business and compensates the other from other assets. Business valuations are one of the more contested aspects of relationship property division.
What if my partner is hiding assets?
Both partners have a duty of full and frank disclosure when dividing relationship property. If you suspect your partner is concealing assets, your lawyer can request disclosure, issue discovery orders through the court, or engage a forensic accountant to trace assets. Deliberate concealment is taken seriously by the Family Court and can result in adverse costs orders or penalties.
Do I need a lawyer for relationship property division?
You are not legally required to have a lawyer to negotiate a property split. However, any binding agreement must be in writing and both parties must have received independent legal advice (section 21, Property (Relationships) Act 1976). In practice, legal advice is essential — people who divide property without advice frequently receive less than their entitlement, particularly in matters involving trusts, income disparity, or complex asset structures.
