10 Reasons to update your Will after a separation

Splitting from a partner can be one of life's most significant transitions. While you're navigating custody arrangements, property division, and new living situations, updating your Will in Christchurch might seem far from urgent. However, failing to revise estate planning documents after a relationship breakdown has the potential to create devastating consequences for your loved ones and your legacy.

Under New Zealand relationship law, separation, whether from marriage or a de facto partnership, does not automatically invalidate or alter your existing Will. This means your ex-partner could still inherit your assets, make critical decisions about your estate, and exercise control over arrangements. Similarly, if your ex is designated under your Enduring Power of Attorney, you must also change these documents and revoke them – the last thing you likely want is your ex having input into health decisions and financial affairs should you lose capacity.

If you do not take action, your ex-partner will continue to hold the powers and entitlements granted to them. This article explains why you need to act quickly and how taking rewriting your Will ensures your wishes are honoured and protects your family's future.

1. Remove your ex-partner as a beneficiary

Weston Ward and Lascelle’s team of wills and estate planning lawyers in Christchurch, swiftly confirmed this as the most compelling reason to update your Will. It’s straightforward yet often overlooked and one of the most common estate planning mistakes following separation: a separation, whether you were married or in a de facto relationship, has no effect on a valid Will.

If you die without making changes, your ex-partner could still inherit under your existing Will exactly as you intended when your relationship was intact. Until you formally revoke your Will by creating a new one, that document remains legally binding. Your former partner may receive your home, savings, investments, or other assets you've since decided should go elsewhere.



2. Remove your ex-partner as executor

If your ex-partner was named as your executor, they retain the legal authority to manage and administer your entire estate unless you update your Will. This means they could remain responsible for valuing assets, paying debts, distributing inheritances, and making final arrangements.

Families can challenge the named executor’s position, but the civil litigation route delays estate administration, increases legal costs and creates avoidable stress for grieving family members during an already difficult time.

3. Appoint new beneficiaries

Separation, divorce or dissolution fundamentally shifts your priorities. Assets you once intended for your partner may now be earmarked for your children, parents, siblings, or close friends. A new Will ensures your estate is distributed to the people who matter most in your life today, not those who mattered when you originally drafted your original Will.

4. Ensure fair distribution for your children

Separation often creates complex family dynamics, especially when children are involved. Stepchildren, biological children from previous relationships, and children from your current relationship all deserve clarity about their inheritance rights.

Updating your Will ensures your children are included and their inheritance is distributed exactly as you intend. You can specify different provisions for different children, accounting for age differences, special needs, education requirements, or existing financial support.

5. Name new guardians for your children

If your ex-partner was named as guardian for your children, or if care arrangements have changed significantly since separation, you must nominate appropriate guardians in your updated Will. While surviving parents typically assume guardianship automatically, complications arise when parents have separated, particularly if there have been concerns about the other parent's capacity to provide adequate care. You may want to update your Will to nominate backup guardians, and this might include grandparents, siblings, or close family friends who understand your parenting values and can provide stability for your children.



6. Protect assets for your children

Beyond simple inheritance, you can use your Will to establish trusts or other protective structures to manage your children's inheritance until they reach maturity. These mechanisms prevent young adults from receiving substantial assets before they're ready to manage them responsibly.

Through a carefully structured New Zealand family trust, you can appoint trustees to manage property, investments, and other assets for your children's benefit, covering education costs, healthcare needs, and living expenses while preserving capital for their future. This proves especially valuable if you've accumulated significant wealth through business solutions NZ ventures or property investments.

7. Address jointly held assets

Jointly held property presents particular complications after separation. While property law in Christchurch dictates how relationship property is divided, your Will should clearly define how jointly held assets will be dealt with to ensure they don't pass to your ex-partner through survivorship rights. Working with experts in property law service and conveyancing Christchurch ensures these assets are properly addressed in your estate planning documents, preventing unintended transfers.

8. Reflect changes in your financial circumstances

Separation invariably affects your financial position. Property settlements, spousal support obligations, and the costs of establishing separate households all impact your net worth. Major changes in your finances or significant changes to your assets require a comprehensive Will review to ensure it aligns with your current financial situation.

You may have received relationship property through separation agreements or acquired assets your old Will doesn't include, in which case updating is essential. Your Will should account for all current assets and liabilities, providing clear instructions for everything you own.
