10 In effect, Ms Mathews seeks to invoke what is known as the rule in Saunders v Vautier (1841) 4 Beav 115; 49 ER 282 (affirmed (1841) Cr & Ph 240; 41 ER 482). The formulation of that rule approved by the High Court in CPT Custodian Pty Ltd v Commisisoner of State Revenue (Vic) [2005] HCA 53; (2005) 224 CLR 98 at 119 is as follows:
" Under the rule in Saunders v Vautier , an adult beneficiary ... who has ... an absolute, vested and indefeasible interest in the capital and income of property may at any time require the transfer of the property to him ... and may terminate any accumulation. "
11 Thus in Gosling v Gosling (1859) Johns 265; 70 ER 423, Sir W Page Wood V-C said (at 272, 426):
" The principle of this Court has always been to recognise the right of all persons who attain the age of twenty-one to enter upon the absolute use and enjoyment of the property given to them by a will, notwithstanding any directions by the testator to the effect that they are not to enjoy it until a later age - unless, during the interval, the property is given for the benefit of another. If the property is once theirs, it is useless for the testator to attempt to impose any fetter upon their enjoyment of it in full so soon as they attain 21. "
12 The point upon which this case turns is the requirement that the adult beneficiary have a vested interest. A person has a "vested" interest in property if he or she has a certain interest in the property even though the right to possession or enjoyment of the property is postponed. Such a person has an estate vested in interest. The estate is vested in possession where the person has a present right of enjoyment. If the person's interest depends upon a contingency which may or may not occur, he or she does not have a vested interest, but a contingent interest.
13 The question whether Ms Mathews is entitled to call for the estate to be paid to her now, or whether she must wait until she turns 30, depends on whether the estate is vested in her in interest. In Marks v Trustees Executors and Agency Co Ltd (1948) 77 CLR 497, Williams J said (at 507):
" The weight of authority would appear to favour the view that in English law vesting means prima facie vesting in interest. But it is unnecessary to examine the authorities because the answer must in every case depend primarily on the context of the particular will ."
