Understanding Separation and Relationship Property Agreements
22 September 2024

Separation and relationship property agreements are crucial legal tools that can be made at any time - before, during, or after a relationship. 

These agreements help clarify who owns what during and after a relationship ensuring that each party knows who owns which assets.

The key law in this area in New Zealand is The Property (Relationships) Act 1976 (PRA). This law says that partners usually share ownership of:

·      the family home;

·      family belongings (like furniture); and

·      any property acquired during the relationship.


The PRA states that any property bought during the relationship is usually considered shared property and is typically split equally if the relationship ends. The family home is treated differently; it is usually shared equally, no matter who owned it before the relationship or how much each partner contributed.


Section 21 Agreements

To ensure a Section 21 agreement is valid, it must meet specific requirements:

·      The agreement must be in writing and signed by both parties.

·      Each party must receive independent legal advice before signing.

·      The signatures must be witnessed by a lawyer.

·      The witnessing lawyer must certify that they explained the agreement’s effects and implications to the signing party.


Even if an agreement satisfies these requirements, a court can set aside (cancel) an agreement if it considers that the agreement would cause serious injustice. For an agreement to be cancelled, this generally depends on whether the agreement was entered into freely and if the terms of the agreement are not fair.

 

Contracting Out Agreements

The couple in the relationship may choose to enter a Section 21 agreement.  This agreement is a legal contract that allows couples to decide how to divide their property if they separate, overriding the default rules set by the Property (Relationships) Act.


Commonly known as ‘pre-nups’, these agreements are essential if you’ve been in a de facto relationship for three years or more, are married, or in a civil union. The PRA applies here. A de facto relationship is defined as “living together as a couple,” which can include not physically living together but demonstrating a commitment to a shared life.


Why have one? If you have any concerns, it’s smart to create a contracting out agreement. These agreements are particularly important in second relationships. Recent legal cases show that putting a home in a trust before entering a PRA relationship won’t protect your assets. Agreements not signed and certified by lawyers won’t hold up in court. These agreements let you decide how to manage your assets and protect certain items if the relationship ends.

 

Post-Separation Agreements

These agreements clarify who keeps what after a separation and whether one person needs to pay out the other to achieve an equal division of the relationship property. It’s important to finalise a separation agreement quickly. Until it’s signed, all shared property remains shared. This means if you buy a house or pay off a mortgage alone, it’s still considered shared property, and your ex could claim it later. They might also have a claim to your estate if you pass away before finalising the agreement.



Separation and relationship property agreements provide important legal protection. Understanding the PRA and the requirements for these agreements helps ensure your assets are safe and ownership is clear. Whether starting a new relationship, currently in one, or recently separated, it’s wise to seek legal advice and consider these agreements to protect your interests.

He taonga to mokopuna, kia whāngaia, kia tipu, kia rea - a child is a treasure, to be nurtured, to grow, to flourish. A common thing we hear from clients is "I want custody of my children." While most people understand what "custody" means, the reality is that custody is no longer a legal term used in New Zealand family law. In fact, the term was removed from our legislation more than 20 years ago. So, what changed? The Care of Children Act 2004 replaced the old concepts of "custody" and "access" with language that focuses more directly on children's needs and parental responsibilities. Instead of talking about custody, the Family Court now talks about: Day-to-day care (who the child lives with and who looks after them on a daily basis); and Contact (the time a child spends with a parent or other important person when they are not in that person's care). The change was intentional. The law moved away from language that can sound like a child is something to be "owned" or "won" by one parent. What does "day-to-day care" mean? Day-to-day care refers to the practical care of a child, including: Where the child lives; Their daily routine; School attendance; Meals, bedtime, and general supervision; and The everyday decisions involved in raising them. A parent can have: Sole day-to-day care; or Shared day-to-day care arrangements. There is no legal presumption that one parent should have day-to-day care over the other. The Court's focus is always on what is in the child's welfare and best interests. What about "contact"? What many people previously called "access" is now referred to as contact . Contact can take many forms, including: Weekend visits; School holiday time; Telephone calls; Video calls; Supervised contact; or Other arrangements that allow a child to maintain a relationship with an important person. The Court recognises that children generally benefit from having ongoing relationships with both parents, provided doing so is safe and in their best interests. Does this mean I can't say "custody"? Not at all. Many people still use terms like "custody," "shared custody," and "access" in everyday conversation, and most lawyers will understand exactly what you mean. However, if you're involved in Family Court proceedings, you'll hear terms such as: Day-to-day care Contact Guardianship Parenting orders These are the legal concepts that will appear in Court documents and orders. Why does the language matter? The shift away from "custody" reflects a broader change in how New Zealand family law views parenting after separation. Rather than focusing on which parent "gets" the child, the law focuses on: The child's welfare and best interests; Maintaining important relationships; Encouraging parents to work together where possible; and Ensuring children are protected from harm. Ultimately, Family Court decisions are not about determining a "winner" and a "loser." They are about creating arrangements that best support the child's wellbeing.
