Titles in the Complete series combine extracts from a wide range of primary materials with clear explanatory text to provide readers with a complete introductory resource. Variation means changing the terms of the trust. The trustees and beneficiaries are bound by the terms of the trust and to disregard these terms is a breach of trust. If the trust is drafted correctly then it should have enough flexibility to deal with future events. This chapter discusses the powers to vary a trust; when the court may consent for beneficiaries under the Variation of Trusts Act 1958; and also the meaning of benefit.
