The Costly Mistake of Outdated Wills: Why One Life Change Can Undo Everything
Most Australians know the importance of having a will — but far fewer realise how quickly it can become outdated. Life doesn’t stand still, and neither should your estate planning documents.
A will that once reflected your wishes can become legally ineffective or even revoked altogether when major life events occur.
Here are some of the biggest triggers that can instantly throw your estate planning off course:
Marriage or Re-Marriage → In Australia, getting married automatically revokes a will unless it was made “in contemplation of marriage.” Many people don’t realise this until it’s too late.
Separation and Divorce → While divorce revokes certain provisions (such as appointing your former spouse as executor), separation alone does not. This can leave ex-partners with unexpected powers or entitlements.
Children → The birth or adoption of children changes your responsibilities dramatically. Without updating your will, your children may not be provided for.
Property Purchases → Buying a home with a partner, especially as “joint tenants,” can override the wishes in your will.
👉 Example:
Sarah wrote her will in her late 20s, leaving everything to her parents. Ten years later, she was married with two children, but never updated her will. Tragically, she passed away suddenly. Because her marriage revoked her earlier will, she died intestate (without a valid will). This meant her estate was divided according to WA’s intestacy laws, creating delays and hardship for her husband and children — something Sarah never intended.
The lesson? Your will isn’t a “set and forget” document. Even a small change in your personal circumstances can completely alter its effect.
➡️ If it’s been more than two years since you last reviewed your will, or if you’ve had a major life event, now is the time to update it.
