Partnerships and cohabitation — New Zealand

De facto relationships of three years attract equal sharing of relationship property — the most far-reaching regime in the common law world.

The legal framework

The Property (Relationships) Act 1976, substantially amended in 2001, applies to marriages, civil unions and de facto relationships alike. After three years, relationship property — including the family home whoever bought it — is presumed to be divided equally. Civil unions remain available to all couples.

Key points

Economic disparityCompensation available where one partner's earning capacity was reduced
DeathThe survivor chooses between claiming under the Act or taking under the will
Three yearsDe facto relationships of three years fall under equal sharing
Short relationshipsUnder three years, only limited claims, mainly where there is a child

In practice

Cost and coverage

Contracting-out agreements require independent advice for both parties, typically costing over a thousand dollars each.

Recent changes

Because the regime applies automatically, New Zealand's biggest practical issue is people discovering the three-year rule only when the relationship ends.

Where to go

Worth knowing

Three years passes quickly, and the family home is the asset most affected: a house bought by one partner before the relationship can become shareable once it is the family home. Equal sharing applies automatically after three years. Many people are inside the regime without any deliberate decision having been made.
