Separated but Living Together in New Zealand: How the Law Applies

It is more common than people realise for couples to separate but continue living in the same home. Sometimes that is because of children. Sometimes it is financial. Sometimes it is simply a short-term arrangement while people work out what comes next.

One of the questions that comes up regularly is this: “If we are still living together, have we actually separated?” The answer, in New Zealand, is not a simple yes or no. Separation is not determined by whether someone has moved out. It comes down to what is actually happening between you.

Under the Property (Relationships) Act 1976, the focus is on whether you are still living together as a couple. That applies whether you are in a de facto relationship, married, or in a civil union. A marriage, for example, technically continues until divorce, but the relationship itself can be over well before that. So you can be separated while still living under the same roof. But only if, in reality, the relationship has ended. The courts do not rely on labels. They look at the overall situation and how the relationship is functioning day to day.

There is no single factor that determines it. It is a combination of things, including whether you are still sharing a bedroom, whether the relationship itself has ended, how finances are being handled, how day-to-day life is organised, whether decisions are still being made together, and how you present yourselves to others. In some situations, people remain financially connected simply because they have to. That, on its own, does not mean the relationship is continuing. But if, overall, life still looks like a shared partnership, it becomes harder to say the relationship has actually ended.

The date of separation can become important later on, particularly if there is a disagreement. It can affect how property is treated, what is included or excluded, how contributions are assessed, and whether one person argues the relationship continued longer than the other accepts. Where people continue living together, it is not unusual for each person to have a different view of when separation actually occurred. That can be difficult, and expensive, to resolve after the fact.

You do not need a formal agreement to be separated. Separation happens through what you do, not whether you have signed something. Where an agreement becomes important is when you want certainty around property. If you are dividing assets, particularly while still living together, a properly structured agreement is usually the safest way to avoid issues later. For that agreement to be enforceable under the Act, it must be in writing, each person must receive independent legal advice, and each lawyer must certify that advice. Without that, an arrangement may exist in a loose sense, but it is much easier for it to be challenged later.

When people stay in the same home after separating, a few patterns come up repeatedly. One person later says the relationship never really ended. There is disagreement about financial contributions. Actions taken at the time are interpreted differently later on. Decisions made years earlier are revisited. None of this is unusual. It is usually the result of things not being clearly recorded at the time.

Living together after separation does not mean the relationship is still ongoing for legal purposes. But it does mean that what you are doing, and how clearly it is understood, matters more. If you are in that situation, it is worth stepping back and asking what your current arrangement actually looks like, whether either of you might take a different view of it later, and whether it would help to record things properly now while everything is still straightforward.
