The 10 year anniversary of the sudden death of Australian motor racing legend Peter Brock is a poignant reminder of the legal wrangles which can be left to the beneficiaries of an estate when a person dies without completing a will which properly sets out their wishes. Following Brock's death in September 2006, it emerged that he had signed a DIY will kit but had not completed the required detail, creating a legal battle between his estranged spouse Beverley, and his partner Julie Bamford. According to the NSW Trustee, up to 50% of Australians do not have a valid will.
