Property (Relationships) Act 1976: What It Means for Your Divorce in NZ

Here's the assumption that trips up most newly separated Kiwis: they think a dissolution order handles the property split. It doesn't. The Family Proceedings Act 1980 ends your marriage. A completely separate piece of legislation — the Property (Relationships) Act 1976 (PRA) — decides who gets what. You can be legally divorced for years while your relationship property remains entirely undivided, still sitting in joint names, still exposed to your ex-partner's decisions.

That gap catches people out, especially when they discover that KiwiSaver balances, the family home, and even a car bought mid-relationship all fall under the PRA's rules — rules that don't automatically apply themselves. Someone has to invoke them, usually through a formal agreement or a Family Court application.

What the Property (Relationships) Act Actually Does

The PRA sets out how relationship property is identified, valued, and divided between separating partners — married, in a civil union, or de facto after three years together. The default position under the Act is a 50/50 split of relationship property, regardless of whose name is on the asset or who earned more during the relationship.

Critically, the PRA operates independently of the Family Court's dissolution process. You can file and finalize a divorce under the Family Proceedings Act without ever touching a PRA claim, and plenty of people do — usually because they've already sorted property privately, or because they haven't gotten around to it. The risk in the second scenario is that unresolved relationship property claims don't disappear; they carry statutory deadlines that start running from your separation date or your dissolution order, and once those deadlines pass, your right to claim a share can be lost entirely.

What Counts as Relationship Property

Relationship property under the PRA is broader than most people expect. It typically includes:

• The family home and chattels, even if only one partner's name is on the title, as long as it was used as the family home during the relationship
• KiwiSaver balances — but only the portion that accrued during the relationship, including employee and employer contributions, government tax credits, and investment growth on those contributions
• Joint bank accounts and any funds earned by either partner during the relationship
• Vehicles, furniture, and other chattels acquired while together
• Business interests built up during the relationship, even if legally owned by one partner

Property owned before the relationship began, along with gifts and inheritances kept separate, generally falls outside the PRA as separate property — provided it wasn't mixed into joint accounts or used to improve relationship assets like the family home.

Contracting Out: Why Section 21 Agreements Matter

Couples can opt out of the PRA's default rules through a Section 21 agreement — a formal contract that sets out exactly how assets will be divided, overriding the statutory 50/50 default. This is the mechanism most separating couples use to divide KiwiSaver, offset one partner's larger balance against other assets, and set the terms for transferring the family home into one partner's sole name.

There's a hard rule here that surprises a lot of people: a Section 21 agreement is completely void and unenforceable unless both partners received independent legal advice from separate solicitors before signing. You cannot use the same lawyer, and you cannot skip this step to save money — doing so means the agreement carries no legal weight at all, and you're back to square one if a dispute arises later. Legal fees for a properly executed agreement typically run from $1,500 to $6,950 or more per side, depending on complexity.

The Clock Is Ticking on Your Claim

The PRA imposes strict time limits, and missing them can mean losing your entitlement outright. For married and civil union couples, you generally have 12 months from the date your dissolution order takes effect to file a formal relationship property application in the Family Court. For de facto relationships, the limit is three years from the date of separation. These deadlines apply whether or not you've reached an informal understanding with your ex-partner — a handshake agreement carries no legal protection if the relationship sours or your ex changes their mind.

If you and your ex-partner can't agree and need the Family Court to decide, the filing fee for a relationship property application is $816, with additional hearing fees of $1,056 per half-day if the matter proceeds to a hearing. That's on top of legal fees, which is why most separating couples try to reach a negotiated Section 21 agreement before resorting to a court application.

Getting It Right the First Time

The PRA's complexity is exactly why so many separating couples end up paying for hours of billable legal time just to understand what they're entitled to before a single negotiation begins. Knowing which assets count as relationship property, how KiwiSaver offsets are calculated, and what documentation your lawyer needs before drafting a Section 21 agreement can save real money in legal fees — and prevent the kind of sequencing mistakes that leave a joint mortgage or KiwiSaver split unresolved months after your divorce is finalized.
