When to update your will: life events that break an estate plan
Most of the estate disputes we act in start with a will that was correct when it was signed and wrong by the time it was needed. Queensland law changes the effect of a will automatically on marriage and divorce, and ordinary life events — selling the house, a second relationship, a child's separation, a business sale — can leave gifts that fail or beneficiaries who were never contemplated. A will is not a document you sign once.

Events that change your will by operation of law
Two life events change a Queensland will automatically, whether or not you intend it.
- Marriage generally revokes a will, except to the extent it was made in contemplation of that marriage, or deals with a gift to the person you married and appoints them as executor.
- Divorce generally revokes gifts to the former spouse and their appointment as executor, though the rest of the will usually stands. Separation alone does not — a separated but undivorced spouse can still inherit everything.
- Entering or ending a registered civil partnership has similar effects.
- A de facto relationship does not revoke a will, but the partner may still have a family provision claim against your estate.
Family changes that call for a review
Any change in who is in the family, or in their circumstances, is a reason to look at the will again.
- A new child, grandchild, stepchild or adoption
- A beneficiary's death, disability, bankruptcy, addiction or relationship breakdown
- A second marriage or blended family, where competing claims are near-inevitable without careful drafting
- An executor who has died, moved overseas, aged, or fallen out with the family
- A child taking over the family business or farm while others do not
- Estrangement — a deliberate exclusion needs contemporaneous reasons recorded properly
Asset changes that can make a gift fail
A specific gift of an asset you no longer own generally fails — the doctrine of ademption. Leaving 'my house at 12 Smith Street' to one child and the residue to another, then downsizing, can accidentally disinherit the first child entirely.
The same happens when a company or trust is restructured, an investment property is sold to fund aged care, or an attorney sells assets under an enduring power of attorney. If the asset mix has changed materially, the will should be re-read against it.
- Buying, selling or refinancing property
- Selling a business or restructuring into a company or trust
- Large changes in superannuation or life insurance balances
- Acquiring assets overseas, which may need a separate will in that jurisdiction
- Moving assets into joint names — jointly held property passes by survivorship, not under the will
The things a will does not control
Superannuation is not an estate asset unless it is directed there. Check whether your binding death benefit nomination is current, whether it has lapsed after three years, and whether a non-lapsing nomination is available in your fund. Life insurance held inside super follows the same nomination.
Jointly owned property passes automatically to the surviving owner, and assets in a family trust or a company are not yours to give away by will. A review should cover the whole picture, not just the will itself.
How often to review
As a rule of thumb, read your will every three years and after any of the events above. A review is usually short and inexpensive; a codicil or a fresh will costs far less than the family provision application that follows a stale document. If capacity is becoming a concern, do not wait — a will made while capacity is clearly intact and properly documented is much harder to challenge.
Frequently asked questions
Does getting married cancel my will in Queensland?
Generally yes. Marriage revokes an existing will unless it was made in contemplation of that marriage, or the relevant gift and executor appointment are in favour of the person you married.
We separated years ago but never divorced. Does my ex still inherit?
Under a will that still names them, yes. Separation does not revoke gifts to a spouse — only divorce or the end of a registered civil partnership does. Update the will as soon as you separate.
Can I just hand-write a change on my will?
No. Marking up an existing will can invalidate parts of it or create doubt about your intentions. Changes are made by a properly executed codicil or, more commonly and more safely, by a new will.
Do I need a new will or a codicil?
A codicil suits a single small change such as replacing an executor. For anything structural — new beneficiaries, blended families, changed assets — a fresh will is clearer and less likely to be disputed.
How often should I review my will?
Every three years, and immediately after marriage, separation, divorce, a death in the family, a birth, a significant change in assets, or a diagnosis affecting capacity.
