What makes a will valid in Australia?
Common question · Wills & Estates · Australia · 23 October 2026
General information from Lawmateanz
In Australia, a will is generally valid if it's in writing, signed by the will-maker, and witnessed by two adult witnesses who are present together when the will-maker signs.
Witnesses shouldn't be beneficiaries, as in some states a gift to a witness can be affected.
Courts can sometimes accept informal wills, such as unsigned documents or notes, if satisfied they reflect the person's intentions, but that's slower and costly.
Marriage generally revokes an earlier will, and divorce can affect gifts to a former spouse. Public trustees and lawyers can prepare wills.
