Navigating relationship property: why experience matters
23 July 2025

 

When a relationship ends or circumstances change, untangling shared property can quickly become complex, emotionally, legally, and financially. Relationship property law provides a framework for dividing assets between partners. Whilst it is a legal process, it is also deeply personal. That’s why having an experienced and trusted advisor is essential.

 

What is relationship property?

The Property (Relationships) Act 1976 (the Act) governs how property is divided when a marriage, civil union, or de facto relationship ends, including when a partner passes away. In most cases, there is a presumption of a 50/50 split of shared property, but exactly what counts as “shared” can be more involved than people realise.

 

Relationship property can include:

 

  • the family home;
  • vehicles and household contents;
  • KiwiSaver and superannuation;
  • income earned during the relationship;
  • any assets acquired together; and
  • any relationship debts.

 

There are also important exceptions and nuances, especially if one partner has brought significant assets into the relationship, or if there are children involved.

 

When the 50/50 rule doesn’t apply

 While equal sharing is the default, there are several situations where the law may allow for a different outcome:

 

  • relationships of short duration (less than 3 years);
  • significant economic disparity between partners;
  • separate property, such as inheritance or pre-relationship assets (not intermingled); and
  • contracting out agreements (previously known as prenups).

 

Couples can choose to “contract out” of the default rules by signing a formal agreement. However, this must meet strict legal requirements in order to be valid and enforceable. One of these requirements is that both parties must have independent legal advice.

 

When children are involved

Children can significantly impact the division of relationship property. The law acknowledges the necessity of protecting a child’s wellbeing, particularly during family transitions.  

 

In these situations, the court may:

 

  • postpone the sale of the family home if it would disrupt a child’s living situation;
  • prioritise stability by ensuring that the primary caregiver can continue to provide a secure environment;
  • acknowledge unpaid contributions, such as caregiving, as equal in value to financial contributions; and
  • apply the Act to relationships of short duration if there’s a child of the relationship.

 

Every family is different and when children are involved, the stakes are higher. That’s why it’s crucial to seek advice that combines legal clarity with compassion and care.

Every situation is different

 

While the law provides a general framework, no two families or relationships are exactly alike. That’s why having thoughtful and experienced legal support makes all the difference. Whether you're entering into a new relationship, separating, or simply planning for the future, clear advice from someone who understands the legal landscape and your personal one is essential.

We’re pleased to shine a light on Marta Black, an Associate in our Dispute Resolution team. Since joining Willis Legal in 2022, Marta has become a valued member of our Dispute Resolution team. She is known for her calm, thoughtful approach, and her ability to bring clarity to even the most complex disputes. Marta works across a wide range of civil litigation, with a particular focus on contentious trust matters and complex relationship property disputes. These areas often involve significant assets and sensitive family dynamics, and Marta is recognised for the steady guidance she brings to her clients throughout the process. Marta appears regularly in the range of courts in the civil jurisdiction. Before entering practice, she worked as a Judge’s Clerk at the High Court. That experience gave her a strong foundation in legal analysis and a close understanding of how complex decisions are made, something that continues to shape her work today.  When asked what motivates her, Marta says she is driven by the challenge of providing accurate, timely, and practical advice. She enjoys the intellectual side of litigation and the satisfaction of solving difficult problems. “ I enjoy a complex puzzle and looking at a problem from all angles to find a solution that delivers results for our clients ,” she says. That mindset has seen her navigate some memorable matters, including acting in a contentious company dispute involving prejudice to shareholders, which ultimately led to a formal proof hearing in related relationship property proceedings. Another standout was a six‑week breach of contract trial in Auckland. It was hard‑fought, strategically demanding, and ultimately successful. Outside work, Marta enjoys the best of Hawke’s Bay life. She loves spending time with her young family and their two beagles, heading to the beach, and embracing her new hobby of camping (or glamping, as she admits with a smile). When asked what she finds most rewarding about her role, her answer is simple: “ Interesting work, with good people .”

LIM and property file information: Councils hold a lot of information about your property. Ordering these documents early gives you a clear picture of what a buyer will see. Building work and consents: If you have made alterations, it is important to confirm that the right consents and code compliance certificates are in place.

Identifying any issues early means you can deal with them on your terms, without pressure once an offer arrives. If you are thinking about buying Buyers benefit just as much from early preparation.
