Update Will After Divorce NZ

Here is a fact that catches most separating New Zealanders off guard: separation does not change your will. If you wrote a will naming your spouse as sole beneficiary and executor, that will remains fully valid and enforceable the day you separate, the day you file for dissolution, and every day until you either revoke it or write a new one.

Under the Wills Act 2007, a dissolution order partially addresses this by revoking any appointment of your former spouse as executor, trustee, or guardian — but only after the dissolution takes effect. Until then, and even after dissolution for beneficiary provisions, the situation is more nuanced than people expect.

What Divorce Actually Does to Your Will

When a dissolution order takes effect in New Zealand, the Wills Act 2007 automatically revokes appointments of your former spouse as executor, trustee, or guardian. However, gifts left to your ex-partner are not automatically revoked — they are treated as if your ex-partner predeceased you, which means the gift falls to the residuary estate or the next beneficiary in line.

The critical gap is the separation period. From the day you separate until the dissolution order takes effect (potentially two years or more), your existing will operates exactly as written. If you die during this period, your ex-partner inherits according to the current will. This is the window people forget about, and it is often the longest and most financially complex period of the entire divorce process.

Dying Without a Will (Intestacy)

If you have no valid will at all, New Zealand's intestacy rules under the Administration Act 1969 determine who inherits. While you are still legally married (even if separated), your spouse is entitled to a share of your estate. The intestacy formula gives your spouse personal chattels, a prescribed amount, and a share of the residue — potentially leaving your children or other family members with far less than you intended.

Writing a new will during separation is not premature. It is the only way to ensure your estate goes where you want it to go if something happens before the dissolution is finalised.

Updating Your Executor and Beneficiaries

A new will should name a new executor (the person who administers your estate), new beneficiaries, and new guardians for any children under 18. If you had your ex-partner as your primary beneficiary, you likely also had them as your executor — both need replacing.

Choose an executor you trust who is not involved in the divorce proceedings. A family member, close friend, or professional trustee company (like Public Trust or Perpetual Guardian) can serve. Your new will completely revokes the old one, so there is no ambiguity about which document governs.

Enduring Power of Attorney

An enduring power of attorney (EPA) is separate from your will but equally urgent. If you gave your ex-partner an EPA for personal care and welfare or property, they retain the legal authority to make decisions for you if you become incapacitated — unless you revoke it.

To revoke an EPA in New Zealand, you must do so in writing while you still have mental capacity. Notify your ex-partner and any institution that holds a copy of the EPA (your bank, your lawyer, your doctor). Then execute a new EPA appointing someone you trust.

Life Insurance Beneficiaries

Life insurance policies operate outside your will. The beneficiary named on your policy receives the payout directly, regardless of what your will says. If your ex-partner is still the named beneficiary on your life insurance, they will receive the payout even if your new will leaves everything to your children.

Contact your insurance provider and update the beneficiary nomination. This is a simple form change but it is frequently overlooked in the administrative chaos of separation.

Don't Wait for the Dissolution Order

The safest approach is to update your will, revoke any EPA naming your ex-partner, and change your life insurance beneficiaries during the separation period — before you even apply for a dissolution order. This closes the gap where your estate is exposed to outdated instructions.
