TSEM6351 | Legal Background to Trusts and Estates: Varying the terms of a trust
From HM Revenue & Customs · Trusts, Settlements and Estates Manual
Sometimes trustees may choose to vary the terms of a trust. All those with an interest that is affected must agree the changes. The courts must sanction the proposal if it could affect the interest of
minors, or
persons unborn, or
beneficiaries, who the trustees cannot at that time, ascertain.
The court can vary the terms of the trust to meet special circumstances, like a divorce.
