Divorce and your will in NSW do not work the way most people expect. Under the Succession Act 2006 (NSW), divorce does not cancel your entire will. It revokes only the gifts and appointments that relate to your former spouse, and only once the divorce order is legally finalised. Until that moment, your existing will operates in full. Your former spouse can still inherit everything you left them, act as your executor, and make decisions on your behalf through any power of attorney you granted. Separation alone changes nothing. That gap between separation and finalisation is where the real risk lives.
How does divorce and your will NSW actually work under the law?
Section 13 of the Succession Act 2006 sets out exactly what a divorce order revokes in your will. The revocation is partial, not total. Your will does not become void. It continues to operate, but with specific provisions removed.
A divorce order revokes the following elements of your will:
- Any gift left to your former spouse
- Your former spouse’s appointment as executor or co-executor
- Your former spouse’s appointment as trustee
- Your former spouse’s appointment as guardian of your children
Everything else in your will remains valid. Your other beneficiaries still receive their gifts. Your other appointed executors still hold their roles. The will is read as though your former spouse died immediately before you.
The critical exception: if your will expressly states that gifts or appointments are to survive a divorce, those provisions remain operative. Courts will give effect to that language. This is rare, but it matters.
The practical consequence is significant. If your former spouse was your sole executor and sole beneficiary, divorce revokes both appointments. But no automatic substitution occurs. No one steps into their role. The estate may then face a partial or full intestacy situation, which distributes assets according to a statutory formula rather than your wishes.
Why separation does not protect your estate
Separation has no legal effect on your will. Your will remains fully operative from the day you separate until the day your divorce order takes effect. That gap is typically 6–12 months at minimum, because NSW law requires 12 months of separation before you can apply for divorce, and the divorce order itself takes effect one month and one day after the hearing.
During that period, the risks are concrete:
- Your former spouse inherits everything you left them if you die before the divorce is finalised.
- Your former spouse can administer your estate as executor, controlling how assets are distributed.
- Your former spouse retains full authority under any enduring power of attorney you granted, including financial and medical decisions.
- Your former spouse remains your enduring guardian if you appointed them in that role.
The law is unambiguous on this point. If you die after separating but before the divorce order takes effect, your will is read as written. Your former spouse inherits as planned.
Pro Tip: Do not wait for the divorce to be finalised before updating your will. Separation is the trigger for action. A new will executed the week after separation is far better than one updated the week after the divorce order.
The risk extends beyond death. If you suffer a serious accident or illness during the separation period, your former spouse can make financial and medical decisions on your behalf under an existing power of attorney. That authority does not end at separation. It ends only when you revoke it.
How to properly update your will and estate documents after separation
Updating your will after divorce in NSW requires more than crossing out your former spouse’s name. Informal handwritten changes to a will are generally not legally valid in NSW. Courts have consistently held that alterations made outside the formal execution requirements of the Succession Act 2006 risk invalidity and dispute.
The correct steps are:
- Draft a new will entirely. This is the cleanest approach. A new will revokes all prior wills and removes any ambiguity about which version applies.
- Name new beneficiaries explicitly. Do not leave gaps. If your former spouse was your primary beneficiary, name a replacement. Without one, those gifts may fall to partial intestacy.
- Appoint a new executor. Choose someone you trust who is capable of administering your estate.
- Sign and witness the new will correctly. Two adult witnesses must be present simultaneously. Neither witness should be a beneficiary under the will.
- Revoke your enduring power of attorney. This requires a formal revocation document. Notify your attorney in writing and update your records with any relevant institutions.
- Update your enduring guardianship appointment. A new appointment replaces the old one, but formal execution is required.
- Review your superannuation binding death benefit nominations. These sit outside your will entirely and require a separate update directly with your superannuation fund.
Pro Tip: Review your estate plans and powers of attorney together as a package. Updating your will without touching your power of attorney leaves a significant gap in your protection.
Legal professionals recommend reviewing your will every 2–3 years or immediately after any major life event. Separation and divorce are the most consequential triggers on that list.
Common misconceptions about wills and divorce in NSW
The most damaging misconception is that divorce cancels your entire will. It does not. Divorce revokes only specific provisions relating to your former spouse. The rest of the will stands. That distinction matters enormously in practice.
A second misconception is that updating your will is sufficient on its own. It is not. Your former spouse can still receive your superannuation death benefit, your life insurance payout, and jointly owned property if you do not address each of those separately.
| Misconception | Reality |
|---|---|
| Divorce voids the entire will | Only gifts and appointments to ex-spouse are revoked under Section 13 |
| Separation changes your will | Separation has no legal effect on your will |
| Updating your will covers everything | Superannuation, insurance, and joint property require separate action |
| Handwritten changes are valid | Informal alterations are generally invalid in NSW |
| Ex-spouse loses executor role at separation | Executor appointment remains until divorce order takes effect |
A third misconception is that your former spouse loses access to non-probate assets automatically. Superannuation death benefit nominations are not revoked by divorce. They operate outside your will entirely. If your former spouse is the nominated beneficiary of your superannuation fund and you have not updated that nomination, they may receive the benefit regardless of what your will says.
Failing to act on these misconceptions creates the conditions for inheritance disputes that are costly, stressful, and often avoidable.
What else does divorce affect beyond your will?
Estate planning after separation extends well beyond the will itself. Three areas require immediate attention alongside your will update.
Joint tenancy property. If you and your former spouse own property as joint tenants, the survivor automatically inherits the other’s share. This right of survivorship operates outside your will entirely. Divorce does not sever a joint tenancy. You must take a formal legal step to convert the ownership to tenants in common, which allows each party to leave their share by will.
Enduring powers of attorney and guardianship. Powers of attorney granted before divorce remain valid unless explicitly revoked. Your former spouse retains authority to manage your finances and make medical decisions until you act. Revocation requires a formal written document and notification to your attorney.
Superannuation and life insurance. Superannuation death benefit nominations must be updated directly with your fund. A binding nomination in favour of your former spouse will be paid to them regardless of your will. Contact your fund immediately after separation and submit a new binding nomination naming your intended beneficiaries.
Coordinating all of these updates together is the only way to fully sever your former spouse’s rights across your estate. Addressing them in isolation leaves gaps that can be exploited or that lead to unintended outcomes.

Key takeaways
Divorce in NSW revokes only the gifts and appointments relating to your former spouse in your will. Separation alone changes nothing, and acting immediately after separation is the single most important step you can take.
| Point | Details |
|---|---|
| Partial revocation only | Divorce revokes gifts and appointments to ex-spouse under Section 13, not the entire will. |
| Separation creates real risk | Your former spouse can inherit and act as executor until the divorce order takes effect. |
| Update all documents together | Will, power of attorney, guardianship, and superannuation nominations all require separate action. |
| Informal changes are invalid | New wills must be formally drafted, signed, and witnessed to be legally effective in NSW. |
| Superannuation sits outside your will | Death benefit nominations must be updated directly with your fund after separation. |
George’s take: the timing mistake I see most often
Most people I speak with after a separation assume the legal system will protect them automatically. They believe that once they tell their spouse it is over, the paperwork catches up. It does not.
The clients who end up in the most difficult situations are those who waited. They waited for the divorce to be finalised. They waited until the property settlement was done. They waited until life settled down. In the meantime, they were in a car accident, or they became seriously ill, and their former spouse was still legally authorised to make every decision on their behalf.
The other pattern I see constantly is the partial update. Someone drafts a new will but does not touch their superannuation nomination. Their former spouse receives a six-figure superannuation payout that the will was specifically designed to redirect. That outcome is not a legal error. It is a planning gap.
My honest view is that estate planning after separation is not a single task. It is a coordinated review of every document that gives another person authority over your assets or your person. A new will is the starting point, not the finish line. If you are unsure whether your documents are fully updated, the safest step is a professional review before the divorce is finalised, not after.
