De Facto Relationship Agreement (New Zealand)

A De Facto Relationship Agreement in New Zealand records how a couple agree to divide their property and finances if the relationship ends, intended to be binding under the Contract and Commercial Law Act 2017.

New Zealand's Property (Relationships) Act 1976 was significantly amended in 2001 to extend its coverage to de facto couples on the same basis as married and civil union couples. Where a de facto relationship meets the qualifying threshold — generally three or more years, or where there is a child of the relationship — the PRA's equal-sharing provisions apply to relationship property on separation or death. This means that the family home, family chattels, and other property acquired during the relationship are generally divided equally between the partners, regardless of who paid for them or in whose name they are registered.

A de facto relationship agreement allows partners to take control of their property arrangements rather than relying on the PRA's default rules. It can be made before the relationship commences (under section 21A of the PRA) or during the relationship. The agreement can designate specific assets as 'separate property' that will not be subject to equal division, specify how household expenses will be shared, address what happens to the shared home on separation, regulate how KiwiSaver balances will be treated, and modify the surviving partner's rights on death.

For the agreement to be valid and enforceable, the strict formal requirements of section 21F of the PRA must be met: the agreement must be in writing, both parties must receive independent legal advice before signing from their own separate lawyers, each signature must be witnessed by an independent adult, and the agreement must not be procured by fraud, misrepresentation, or undue influence. Courts have the power to set aside agreements that are seriously unjust or that were made without full disclosure of assets.

De facto relationship agreements interact closely with wills and estate planning. Under Part 8 of the PRA, a surviving de facto partner has the right to claim an equal share of relationship property on the death of their partner, and this right can be modified or waived by agreement. Partners should review their wills when entering into a de facto relationship agreement to confirm consistency.

A De Facto Relationship Agreement is needed in New Zealand whenever a couple who are living together or about to live together as a de facto couple wish to clearly define their respective property rights and to provide certainty about what will happen to their assets if the relationship ends. Common situations include:

Protecting pre-existing assets: One or both partners own significant assets before commencing the de facto relationship — such as a home, investment property, business, or substantial savings — and wish to confirm those assets remain their separate property if the relationship ends.

Business protection: One partner owns or has a significant interest in a business and wishes to confirm that the business and its goodwill remain separate from the relationship property pool and are not subject to division at the end of the relationship.

Children from previous relationships: One or both partners have children from a previous relationship and wish to protect certain assets — particularly the family home — for the benefit of those children rather than allowing them to become relationship property subject to division with the new partner.

Financial disparity: There is a significant disparity in the financial positions of the two partners (for example, one partner is substantially wealthier than the other), and the wealthier partner wishes to confirm that the weaker party does not acquire rights to a disproportionate share of their assets through the operation of the PRA.

Estate planning coordination: The partners wish to coordinate their de facto relationship agreement with their respective wills and estate plans, particularly regarding the surviving partner's rights under Part 8 of the PRA on the death of their partner.

Clarity before cohabitation: Two people are about to begin living together and wish to establish clear and agreed ground rules about their property rights from the outset, avoiding the ambiguity and potential disputes that can arise when the relationship ends without a prior agreement.

A thorough New Zealand De Facto Relationship Agreement should include the following key elements.

Parties and cohabitation details: Full legal names, dates of birth, and addresses of both partners. The date the de facto relationship commenced or will commence, and the shared residential address.

Statutory basis: A clear statement that the agreement is made under sections 21 and 21A of the Property (Relationships) Act 1976, and that the agreement contracts out of the PRA's default provisions to the extent specified.

Separate property schedules: A detailed list of the specific assets each partner brings to the relationship and wishes to retain as separate property. Schedules should be specific and thorough — including real estate (with Land Registry certificate of title references), vehicle registrations, bank account balances, KiwiSaver balances, business interests, and significant personal property.

Financial arrangements during the relationship: How household expenses will be shared, whether the parties will maintain a joint bank account, and how contributions to joint expenses will be structured.

Treatment of relationship property: A statement of how property acquired jointly during the relationship (relationship property) will be divided if the relationship ends — whether equally, in proportion to contributions, or as agreed at the time of separation.

Family home provisions: Specific provisions about the shared home, including: who owned it before the relationship; whether it has become or will become the family home; how it will be dealt with on separation (who has the right to purchase the other's share; valuation process; timelines); and what happens if neither party wishes to retain the home.

KiwiSaver provisions: A clear statement of how KiwiSaver balances accumulated before and during the relationship will be treated on separation.

Debt allocation: Who is responsible for debts incurred before the relationship, and how joint debts incurred during the relationship will be allocated on separation.

Rights on death: A statement of whether the surviving partner retains or waives their rights under Part 8 of the PRA to claim an equal share of relationship property on the death of their partner.

Independent legal advice confirmation: Confirmation that both parties received independent legal advice before signing, from named lawyers.

Disclosure acknowledgment: A mutual acknowledgment that both parties have disclosed all material property and liabilities to the other as at the date of the agreement.

Variation and review: A provision specifying how the agreement may be varied (only by written agreement complying with section 21F of the PRA) and recommending periodic review when circumstances change significantly.
