Separation Does Not Cancel a Will in Queensland — What Divorce Actually Changes

Under Queensland law, separation does not cancel a Will.

Many people assume it does, creating risk during the separation period.

Here is exactly how separation, divorce, and the end of de facto relationships impact your Will under Queensland law.

The “Separation Trap” (Why Separation Does NOT Cancel Your Will)

In Australia, you must be separated for 12 months before you can legally apply for a divorce. This creates a high-risk window known as the “Separation Trap.” A divorce only takes legal effect once a court grants a divorce order. Until then, your Will still governs estate administration.

If you are married, simply separating from your spouse does not revoke or change your Will in Queensland. Your existing Will remains completely valid and binding.

If you pass away during this separation period before the divorce is legally finalised:

• They can inherit: If your current Will leaves everything to your estranged spouse, they will still receive your estate.
• They can be in charge: If you named them as your executor, they will retain the legal right to administer your estate.
• Even without a Will: If you die without a Will (intestate) while separated, your estranged spouse may still be entitled to a share of your estate under Queensland intestacy law.

The Real-World Risk

Imagine this scenario: You separate from your spouse but have not updated your Will. Eight months later you unexpectedly pass away. Because the divorce is not yet finalised, your former partner may still inherit under the existing Will and administer the estate. This occurs because the Will remains legally operative until revoked.

How a Finalised Divorce Affects Your Will

Once the Federal Circuit and Family Court officially grants your divorce order, the law finally steps in. However, a divorce does not revoke the entire Will.

Under section 15 of the Succession Act 1981 (Qld), a finalised divorce automatically revokes by operation of law:

• Any gifts or assets left to your former spouse.
• The appointment of your former spouse as your executor, trustee, or guardian.

The rest of your Will remains legally valid; the Will is interpreted as if your former spouse had died before you. This is known as the “deemed death” rule within succession law. By contrast, remarriage revokes your entire Will; divorce only revokes the parts relating to your ex-spouse. These rules are set by Queensland succession legislation and applied by the courts when administering estates during probate administration after death.

Note: There is a rare exception. If you appointed your ex-spouse as a trustee for property left specifically on trust for their children, that specific appointment may remain valid.

Important: Even after a divorce removes a former spouse from your Will, they may still challenge the estate if they can prove financial dependency. Courts consider the terms of an updated Will when assessing these claims.

What About De Facto Relationships?

For de facto couples, the rules operate similarly but with a massive catch. Under section 15B of the Succession Act 1981 (Qld), the formal end of a de facto relationship revokes gifts and executor appointments relating to your ex-partner.

However, unlike a divorce—which has a clear, court-stamped date—the exact “end date” of a de facto relationship can be highly ambiguous and heavily disputed by family members. Courts assess factors such as living arrangements, financial separation, and communication of the relationship breakdown. Because there is no formal “divorce certificate” for de facto couples, relying on automatic revocation can lead to estate disputes. A new Will removes this uncertainty. Disputes about this date are a common source of estate litigation. If the court finds the relationship had not legally ended, the revocation may not apply. In those cases, the court determines whether the former partner remains a beneficiary.

Common Separation Mistakes in Queensland

• Assuming separation changes your Will — it legally does nothing.
• Assuming divorce updates super — fund rules still apply.
• Forgetting joint tenancy — property transfers outside the estate.
• Leaving ex as executor — they still control administration.

Do You Need to Update Your Will?

Two Additional Estate Planning Steps After Separation

When you make that new Will you’ll need to choose an executor; who can be an executor in Queensland explains the options. Writing a new Will is step one, but a comprehensive estate plan requires two more steps after a separation:

1. Sever Your Joint Tenancy: If you own a home as “joint tenants” with your ex, the surviving owner automatically receives the property interest if you die first, regardless of what your new Will says. Severing joint tenancy means the property does not automatically pass to the surviving owner outside the estate. If you pass away before your family law property settlement is finalised, your estate may need to continue the proceedings.

2. Update Your Superannuation: Your Will does not automatically control superannuation. You must update your binding death benefit nomination with your fund. If you only have a non-binding nomination, the trustee may still pay the benefit to a former partner depending on fund rules and eligible dependants.

The Bottom Line

Only a new Will determines who administers and receives your estate under Queensland succession law. If you later remarry, remember that marriage revokes your Will entirely; divorce only revokes the parts relating to your ex-spouse.
