How Getting Married or Divorced Can Revoke Your Will

September 3, 2025

A person's Will in Western Australia is generally revoked by marriage or divorce, unless it's made with their specific intention to marry or divorce clearly stated in the Will (or there is other evidence which establishes this intention).


What Happens If You Get Married


  • Under section 14 of the Wills Act 1970 (WA), marriage automatically invalidates your existing Will, unless your Will expressly states it was made "in contemplation of marriage" to your intended spouse.


  • If your Will is invalid and you pass away, your assets will be divided according to WA's intestacy laws, which may not reflect your wishes.


  • The best practice is to obtain a new Will after marriage to ensure all your assets and intentions for your loved ones are protected.


What Happens If You Get Divorced


  • Section 14A of the Wills Act 1970 (WA) outlines that divorce also cancels your Will unless your Will shows a clear intent for it to remain valid after divorce.


  • Practically speaking, the automatic revocation in section 14A makes sense, as it is unlikely that you would still want to appoint your former spouse as the Executor of your Will, or provide for them from your estate, after you have divorced.


  • However, if you do not update your Will after divorce, there may be unintended consequences, such as assets going to your ex-spouse or confusion and disputes among family members.


Why Updating Your Will Matters


  • Failing to update your Will after marriage or divorce can lead to estate mismanagement, litigation, or your wishes not being honored.


  • If your relationship status has changed, make an appointment to create or update your Will so all provisions accurately reflect your current wishes and protect your loved ones.


  • This is especially important for blended families, business succession planning, and unique asset structures.

At Crabtree Legal, we understand that protecting your children’s inheritance from potential relationship breakdowns is a crucial concern for many families. The landmark Family Court of Australia decision in Bernard and Bernard [2019] FamCA 421 confirmed that testamentary trust Wills can be an effective tool in safeguarding a beneficiary’s inheritance from being divided upon divorce. Background of the Case In Bernard v Bernard, the husband’s late father created two discretionary testamentary trusts through his Will — one for his son and one for his daughter. The trusts operated as “mirror trusts”: each sibling was the trustee of the other’s trust but had no control over their own trust. The husband was the primary beneficiary of his trust, but the assets were legally owned and controlled by his sister as trustee. When the husband and wife later separated and divorced, the wife sought to have the husband’s inheritance held in the testamentary trust included in the matrimonial property pool for division. However, the husband argued that since he did not legally own or control the trust assets, and his interest was solely as a beneficiary dependent on the trustee’s discretion, the inheritance should be excluded from the property pool. Court’s Decision and Key Findings The Family Court ruled in favor of the husband, finding that the assets in the testamentary trust were not part of the matrimonial pool. The court’s key reasoning was that: The husband was not the settlor of the trust—the deceased father was. The husband had no legal ownership or control over the trust assets. The trustee (the husband’s sister) had complete discretion over income and capital distributions. The husband’s interest was discretionary and not guaranteed, meaning he could not compel distributions. The trust assets were inherited and not acquired during the marriage. This decision confirmed that a properly structured testamentary trust can protect a beneficiary’s inheritance from being divided upon divorce by separating legal ownership and control from mere beneficial interest. Why This Matters for Your Estate Planning Bernard v Bernard highlights how testamentary trust Wills can be used to safeguard your children’s inheritance from future relationship breakdowns, ensuring that inherited assets remain protected within the family and are not treated as divisible property in the event of a divorce.

Crabtree Legal extends our sincere thanks to The Executive Centre for graciously hosting yesterday's Member Showcase lunch event, where our Director, Jonathan Crabtree, had the pleasure of presenting to fellow business owners. The session explored the limitations of Artificial Intelligence (AI) in drafting key legal documents for start-ups and Small to Medium Enterprises (SMEs). Together, we examined common pitfalls that arise when relying solely on automated drafting tools, including the risks of incomplete agreements, unenforceable clauses, and loss of commercial protection. We are particularly grateful to the business owners and entrepreneurs who attended and contributed to the discussion. Your questions, insights, and shared experiences sparked an engaging and practical conversation about balancing technological progress with the value of tailored legal advice. At Crabtree Legal, we remain committed to helping Perth’s business community make informed decisions as they grow and protect their ventures.
