"The court must then determine first whether it is satisfied that adequate provision was not made from the estate for the proper maintenance and support of the [appellant]. That calls for an assessment of whether the provision made for him was inadequate for what, in all the circumstances, was the proper level of maintenance etc., appropriate for the [appellant], having regard to, among other things, the [appellant]'s financial position, the size and nature of the deceased's estate, the totality of the relationship between the [appellant] and the deceased, and the relationship between the deceased and other people who have legitimate claims on her bounty. ... The question of the adequacy, or inadequacy, of the provision made is not to be decided in a vacuum, or by looking simply to the question whether the [appellant] has enough upon which to survive or live comfortably. Adequacy or otherwise will depend upon all of the relevant circumstances, which include any promise the deceased made to the [appellant], the circumstances in which it was made, and, changes in the arrangements between the parties after it was made. Those matters will however never be conclusive. The age, capacities, means, and competing claims, of all the potential beneficiaries must also be taken into account and weighed with all of the other relevant factors: Vigolo v Bostin [2005] HCA 11; (2005) 221 C.L.R. 191 at p.231 per Callinan and Heydon JJ."[10]
