What happens during a separation in New Zealand?

A separation is a significant event and a distressing time. In New Zealand, the process of separating involves understanding how assets and liabilities will be divided, with the presumption of a 50/50 split under the Property (Relationships) Act 1976. Here are the key things you need to consider when dividing your relationship property and the essential steps for preparing for your first meeting with your lawyer.


When dividing relationship property, it is generally governed by the principle of equal sharing. This means that any property acquired during the relationship is typically divided equally between partners.

Presumption of 50/50 Division

The law presumes that relationship property should be divided equally unless there are compelling reasons to deviate from this principle. Factors that may influence the division include the length of the relationship, contributions made by each partner, and any economic disparities that may exist or continue after the relationship ends. For instance, if one partner was a stay-at-home parent for ten years of the relationship and now can only work part-time, this may be used to assist with an economic disparity claim.

Claims for Economic Disparity

Economic disparity claims can arise when one partner has significantly lower income or financial resources compared to the other, potentially due to sacrifices made during the relationship, such as caregiving or homemaking. However, claims for economic disparity cannot be determined until a full review of the assets and liabilities has been completed. Both parties must seek legal advice to see whether they have grounds for an economic disparity claim.

Contracting Out Agreement

Couples may choose to enter into a contracting out agreement (also known as a prenuptial or separation agreement) before or during the relationship. A contracting out agreement cannot be entered into when a couple intends to separate. These agreements allow partners to specify how their property will be divided in the event of separation. 


If a valid contracting-out agreement exists, it will take precedence over the default provisions of the Property (Relationships) Act. This means that the agreed-upon terms will govern the division of property, which may differ from the typical 50/50 split.



Family Trusts and Relationship Property

Family trusts can complicate the division of relationship property during separation. When a family trust is involved. Generally, if the trust was established during the relationship and the assets were acquired with relationship property, they may be considered relationship property subject to division. However, a careful review would need to be conducted to identify whether Trust property has become intermingled and forms part of the relationship property pool.


Preparing for your meeting with your Divorce Lawyer

1. Establish a Separation Date

The new Trust Act requires that the Trustees meet at least annually to discuss the Trust's affairs. The Inland Revenue Department also requires that Trusts (including dormant Trusts i.e. that only hold the family home) file an income tax return (form IR6); comply with additional disclosures, and prepare financial statements.

2. Compile a List of Assets and Liabilities

Gather detailed information on all relationship property, including properties, bank accounts, investments, and personal belongings. Similarly, document any debts or liabilities incurred during the relationship. This can be jointly held or in one party’s sole name.

3. Seek Legal Advice

Engaging a lawyer with expertise in family law can provide valuable guidance throughout the separation process. Legal professionals can assist in understanding rights, obligations, and the implications of any existing agreements. A binding separation agreement can only be established once both parties have been independently advised by their lawyers.

4. Consider Mediation

Before resorting to legal proceedings, both parties should first consult their own lawyers and attempt to negotiate directly with one another (only if you have an amicable relationship with you ex-partner). If negotiations fail, you can then return to your lawyer to assist with the negotiation. This approach can be more cost-effective and help both partners reach a mutually agreeable solution.

5. Engage a Mortgage Adviser and Accountant

Both parties need to involve mortgage advisors and accountants (if one party is self-employed or owns a business) early in the process. Mortgage advisors can assess whether refinancing options are available to remove one party from shared debts, while accountants can help evaluate the financial implications of the separation. This can include determining what each party can afford, particularly regarding the family home.

When dividing relationship property in New Zealand, this is usually done on the presumption of a 50/50 split. However, circumstances such as economic disparity claims, contracting out agreements, and family trusts can influence the outcome. By preparing adequately, seeking professional advice, and engaging in open communication, individuals can avoid a prolonged dispute and settle the matter as promptly as possible.

As a self-employed person, managing your finances and protecting your assets is crucial. One effective way to achieve this is by establishing a family trust. A family trust serves as a mechanism for holding assets, ensuring that your property is managed for the benefit of beneficiaries (which usually includes you). Here’s why a family trust is essential for self-employed individuals, particularly those facing risks from creditors or operating in industries where some risks are not covered by insurance i.e. WorkSafe fines.

Blended families and second relationships are becoming increasingly common in New Zealand; however, the default provisions of the Property Relationships Act 1976 may not fairly protect people entering a second relationship. When partners from previous relationships come together, especially with children in the mix, thoughtful planning is needed to ensure that everyone's needs are met and potential conflicts are identified and addressed. This can prevent a significant amount of stress and costs. Here are some key things to consider if you’re in a second relationship:

According to Consumer NZ, $22.6 billion in loans have been made by the Bank of Mum and Dad, or "the BOMD." This translated into an average contribution of $108,000 from 208,638 parents. You might consider borrowing money from a family member if you are in a position where you have the serviceability (the capacity to meet good levels of borrowing) but need a larger deposit. This implies that you could buy a house and borrow the deposit from BOMB instead of having some or all of it saved. After a while, you might consider refinancing and using your savings or the equity you have gained in the property to pay back the deposit loan. If it is planned and structured correctly, this can be an effective way to get onto the property ladder. Without it, it can have serious legal and emotional repercussions and tax impediments. One way to look at it is that the money you were using to save for a deposit can now be used to repay the loan on the deposit, while the money you were previously spending on rent is now going towards your mortgage and other household expenses. Your first course of action should be to get your financial situation assessed by your bank, or better yet, a mortgage adviser. It is crucial that all parties get independent legal, financial, and tax advice before putting any possible structure into place or sending money.  The type of assistance typically provided by the BOMB could be one or more of the following; Contributing towards the deposit Acting as guarantor Buying a property in partnership with them Buying a property on their behalf
