Contracting Out Agreements (often referred to as prenuptial agreements) are often viewed quite negatively. They can be seen as having one foot out of the door in a relationship. However, Contracting Out Agreements can be powerful tools to help you and your partner cement your intentions for how your property is dealt with when you die thus preventing a future argument between families. A Contracting Out Agreement is not just for separating couples – it can assist to ensure your wishes are upheld upon death.

When you pass away with a Will, your partner has two options; they can chose to follow the terms of your Will pursuant to the Administration Act 1969 (“Administration Act”) or they can make an election under the Property (Relationships) Act 1976 (“PRA”) to have their share of relationship property determined.

Why does this matter?

This matters because modern relationships are complex. For a multitude of reasons you may not intend to leave your partner 50% of your property upon death. For many of our clients in second relationships, they want to provide for their partner, but they want the majority of their estate to go to their children from their first relationship.

The option for partners to elect whether or not to follow your Will, can take control of your property out of your hands leaving what you may see as an unfairness to your children. This is why a Contracting Out Agreement can be such a powerful tool.

With a Contracting Out Agreement in place, even if your partner elects a determination for a division of your estate in line with the PRA, they are bound by the terms of the Contracting Out Agreement which determines which assets are in the pool for division and which are out.

What does a Contracting Out Agreement do?

Under the PRA there is a presumption that upon death or separation your partner is entitled to an equal share of the relationship property. This legislation will apply to you unless you elect to “opt out” by entering into a Contracting Out agreement whereby you and your partner reach your own agreement on what property will be determined separate property and what will be relationship property.

Without a Contracting Out agreement relationship property includes:

  • The family home;
  • The household chattels;
  • Vehicles used for family purposes;
  • That share of Kiwisaver or other superannuation policies accrued during the relationship;
  • Your income; and
  • Anything else acquired during the relationship or used for your shared life together.

A Contracting Out Agreement is capable in most circumstances of mirroring the terms of your Will. It has the capacity to be very specific. Not only can you dictate which property belongs to which partner and their estate, you can also make special provisions for your partner upon separation or death.

An example of this is in circumstances where you want the family home to pass to your children or some other third party upon death, you can still provide your partner with a qualified life interest in the home.

You may decide, for example, that you wish for your partner to continue living in the home for a specific period of time (or the rest of their life) but as soon as they move out, start a new relationship, or die, the home will pass to your beneficiaries in accordance with your Will. A Contracting Out Agreement is a flexible tool capable of reflecting your Will.

How do we make a Contracting Out Agreement?

A Contracting Out Agreement is a binding legal document. Like most legal documents, there are specific procedures that must be followed to make sure your document is enforceable.

For your Contracting Out Agreement to be valid and legally enforceable you will need to:

  • Record the agreements reached in writing;
  • Receive independent legal advice; and
  • Have your signing witnessed by a lawyer.

You and your partner will need different lawyers. Once you have engaged a lawyer, you can share your intentions for how you want your relationship property to be divided and any specifications for what you want to happen upon death. Lawyers can assist you and your partner to make sure you are both adequately provided for.

If you have concerns about how your estate will be distributed when you die, we recommend that you discuss matters with your partner and get some advice.

Furthermore if you already have a Will or a Contracting Out Agreement, we recommend that you review the terms of these documents regularly to ensure they still reflect your intentions and your circumstances.Talk to the Holland Beckett Family or Succession and Estates team for more information.
