A beneficiary whose interest has not yet vested may still need money now, and the statute steps in where the trust instrument is silent. This chapter opens with an overview of the two powers and the property each deals with, then works through maintenance: who is eligible, whether a contingent interest carries intermediate income, the factors trustees weigh, and the fate of surplus income that is accumulated rather than spent. It then traces what changes at 18, when the discretion gives way to a duty to pay income, and what happens to accumulations if the beneficiary dies before vesting. Finally it sets out the section 32 power of advancement — its conditions, the meaning of 'advancement or benefit' — before drawing the distinctions between the two powers and showing how Saunders v Vautier lets a sole adult beneficiary collapse the trust altogether.
