A beneficiary may have to wait years for capital, yet trustees can release it early — provided every statutory safeguard is met, since a flawed advancement is a breach of trust. This chapter starts with the source and nature of the power and which categories of beneficial interest qualify, then sets out the conditions for a valid advancement and the limit on how much of a share may be advanced. It moves on to what counts as the beneficiary's advancement or benefit, when the written consent of a prior interest holder is needed and the consequence of proceeding without it, and the fiduciary duties, unanimity and payment rules — including for minors — that govern the exercise itself. It closes with how earlier advances are brought into account on final distribution and how the trust instrument can exclude, restrict or extend the statutory power.
