I’m an author with a plot problem. Kaye dies in NSW in 1962. Her only living relative is a brother who dies the same time. He has 3 kids. Kaye’s will has gone astray in a solicitor's office in Beechworth and no one knows it exists. Her estate is willed to only the 1st of the 3 kids. The State Trustee distributes the estate, perhaps in trust until they reach 21? The missing will is found after 55 years but the sister-in-law has only given the money to the other 2 kids. Does the 1st child have any claim on the original estate?
