Unlike entering into a marriage or civil union, there is no clear legal line or date as to when a  de facto relationship begins. This means that determining whether a couple is in a de facto  relationship will be a matter of evidence.

The Property (Relationships) Act 1976 (the Act) defines a de facto relationship as a  relationship between two people (irrespective of gender) who are both 18 years or older,  who live together as a couple, and who are not married or in a civil union with each other. It  is in the “living together as a couple” aspect of the definition where the waters can become  murky as, while sharing a home together can be an important indicator of a de facto  relationship, it is not essential.

In deciding whether two people are living together as a couple, the Court will consider a  number of factors, including:

  1. The duration of the relationship; 
  2. The nature and extent of the parties’ living arrangements; 
  3. Whether or not a sexual relationship exists; 
  4. The degree of financial dependence on each other for money, and whether one party  supports the other; 
  5. The ownership, use, and purchase of property; 
  6. The degree of mutual commitment to a shared life; 
  7. The care and support of children; 
  8. The performance of household duties; and 
  9. Whether they are viewed as a couple publicly.

The Court has the discretion to take any and all of the above factors into consideration to  determine whether two people were living together as a couple but none of the factors are  compulsory. Therefore, it can be found that two people were living together as a couple even  if they did not live under the same roof. This means it can sometimes be difficult to know  when property consequences can start flowing from a relationship.

Once a couple has been in a de facto couple relationship for three years, the provisions of  the Act will apply to determine the division of assets and liabilities should that relationship  end (through separation or death). Generally speaking, the presumption under the Act is that  all relationship property will be divided equally between the couple. This means that the  value of property put towards or acquired during the relationship, such as the family home,  household chattels, vehicles, income and KiwiSaver, will be shared equally between the  couple when the relationship ends. This can come as a shock to someone who believed that  they were not (for varying reasons) in a de facto relationship.

If you have concerns about the classification of your relationship, we recommend you seek  legal advice early to ensure your property is dealt with in the manner suited to you if your  relationship ends. This can be achieved by entering into an agreement (often called a pre-nup agreement), which must comply with the requirements of the Act to be effective, with  your partner to contract out of the presumption of equal sharing under the Act and determine  how a division of assets would occur.
