The exposure runs further than money. Administering a trust contrary to its terms is a breach of trust, and Prob. Code § 15642 lists breach of trust among the grounds for removing a trustee, along with unfitness and substantial inability to manage the trust property. A trustee removed for breach can also lose compensation and be surcharged for the loss. The protection available is straightforward and underused: under Prob. Code § 17200 a trustee may petition the probate court concerning the internal affairs of the trust, including for instructions or for approval of a proposed modification, and a court order entered after everyone has been given notice and an opportunity to object is what actually insulates the trustee. That is the right move whenever the beneficiaries want something the document does not authorize, and whenever a minor or unborn beneficiary's share is affected, because those interests cannot consent to anything. The underlying power to change an irrevocable trust belongs to the settlor and beneficiaries under Prob. Code § 15404, to the consenting beneficiaries under § 15403, or to the court under § 15409, and the trustee's role is to bring the question rather than to decide it. An informal email chain saying everyone is fine with it protects no one.
Fixing or Changing a Trust · California
Does the trustee need court approval to change a trust?
In most cases the trustee is not the person who can change the trust at all, with or without a court. A trustee's job is to administer the trust according to its terms, not to rewrite them, and the question a trustee should be asking is not whether the change needs court approval but what happens to the trustee personally if it goes through without one. The pressure is usually sympathetic rather than sinister. The beneficiaries all want the house sold early, or the shares split differently than the document says, or a distribution made to a sibling who is in trouble. Everyone assures the trustee that this is what Mom would have wanted, and the trustee, who is generally one of the children, would like to keep the peace. But a trustee who signs a document purporting to amend a trust, or who simply administers the trust the way everyone now wishes it read, is acting outside the instrument. The liability is personal, measured by what the trust or the shorted beneficiary lost, and it is not covered by the fact that the people in the room agreed.
