3 The relevant provisions of the deceased's will have the effect that his executors hold his estate on trust, first, to pay to Julie a lump sum of $100,000 indexed to the CPI; secondly, to pay annual cash payments to Julie according to a formula on a sliding scale of $45,000 per annum net of tax indexed to the CPI until Julie attains aged seventy, the $40,000 per annum net of tax indexed to the CPI until she attains seventy-five, and thereafter $35,000 per annum net of tax indexed to the CPI; thirdly, to pay all costs and expenses associated with Julie's principal residence; fourthly, to pay to each of his four children an annual cash payment of between $10,000 and $16,000 according to a formula indexed to the CPI and age dependent; fifthly, to pay to any grandchild of the deceased born before or within ten years from the date of his death (of which Lucas is presently the only one), an annual cash legacy of $10,000 (to be shared with any sibling of such grandchild) until attaining the age of twenty-one years; sixthly, to hold the residue of the estate in four testamentary trusts, one in respect of each of his four children, in respect of which the eligible beneficiaries are the nominated child, their children, and grandchildren, so that any of the capital or income of the trust can be distributed to any of the eligible beneficiaries at any time, at the absolute discretion of the executors as trustees. Each child can become sole trustee of his or her own trust, but only on attaining the age of forty-two; and if any child's trust fails then that trust, or the failed part of it, is to be distributed equally between the other children's trusts in existence at that time, or if any part of the estate is still incapable of being distributed under the provisions of the will, then to Julie, or if she is not alive at the relevant time, to the Cancer Council of New South Wales.
