Core Legal | Commercial Property Lawyers in Masterton & Wellington

A landmark New Zealand case has confirmed that the Family Court can divide relationship property involving more than two partners. The decision signals an important development in how the law responds to modern relationship structures and highlights the importance of understanding your legal rights when significant assets are involved.

At Core Legal in Masterton and Wellington, we help clients navigate complex relationship property matters. This recent ruling demonstrates why early legal advice is essential — particularly when property ownership does not fit traditional relationship models.

Polyamorous Relationship Leads to Complex Property Dispute

The case involved three individuals who were part of a polyamorous (multi-partner) relationship and lived together in a jointly owned home for approximately 15 years. Two of the partners were married, while the third had been in the relationship for more than three years.

After the relationship ended, the parties were unable to agree on how to divide their assets — most notably the family home, which had a capital value of $2.175 million in 2017. One partner applied to the Family Court seeking an order for division of relationship property.

Initially, both the Family Court and the High Court declined to decide the matter, stating they lacked jurisdiction because the Property (Relationships) Act traditionally applies to relationships between two people.

Appeals Clarify the Law

The case was appealed to the Court of Appeal, which overturned the earlier decisions. The Court ruled that the Family Court does have jurisdiction to determine relationship property disputes involving multi-partner relationships, provided the legal criteria for a qualifying relationship are met.

One of the partners then appealed to the Supreme Court. However, the Supreme Court upheld the Court of Appeal’s decision, confirming that the Family Court can make orders dividing property in polyamorous relationships just as it does for marriages, civil unions, and de facto partnerships.

The matter was subsequently returned to the Family Court for a final determination.

Family Court Orders Equal Division

The Family Court considered three key questions:

• Did the relationship qualify under New Zealand relationship property law?

• How should the property be divided?

• Were any adjustments necessary?

The Court found that the relationship met the requirements of a qualifying relationship under the Property (Relationships) Act. Because two partners were married and the third had been involved for longer than three years, the principle of equal sharing applied.

As a result, the Court ordered that the family home be divided three ways. One partner was required to pay more than $600,000 to each of the others to buy out their respective shares.

Why This Decision Matters

This ruling reflects the evolving nature of relationships in New Zealand and demonstrates that the courts are willing to apply existing legislation to modern family structures.

Without a clear agreement in place, dividing property after a separation can become legally complex and financially significant — especially when high-value assets such as real estate are involved.

Whether you are entering a non-traditional relationship, purchasing property with multiple partners, or separating after a long-term relationship, understanding your legal position is critical.

Protect Yourself with Proactive Legal Advice

Failing to properly address relationship property rights can be an expensive mistake. Contracting out agreements (often called prenups) and property sharing agreements can help clarify expectations and reduce the risk of disputes.
