Some legal changes announce themselves with dollar figures. Others move quietly through the plumbing. California’s adoption of virtual representation for trusts is the second kind: no new limits, no new forms, and a real effect on how quickly and cheaply an ordinary trust administration can move.
Effective January 1, 2026, AB 565 rewrote Probate Code section 15804. The short version: a beneficiary whose interest in a trust is substantially identical to another’s can now receive notice for, represent, and bind that other beneficiary when the other cannot act for themselves. With the change, California joins the approach used, in one form or another, by the large majority of states.
The problem the old rule created
Trust law has always had beneficiaries who cannot speak for themselves. A trust for the settlor’s descendants includes children who are minors, relatives who may be incapacitated, and, in the strict legal sense, people who do not exist yet: grandchildren not yet born, or a class of heirs that cannot be finally identified until some future death. The law calls for these interests to be protected whenever a trust matter requires notice or consent.
Under the old California rule, protection usually meant a guardian ad litem: a court-appointed representative for the minor, incapacitated, unborn, or unascertainable beneficiary. That appointment is a court proceeding of its own, with fees and calendar time attached, and in a routine matter, an uncontested accounting, a technical modification, a notice of proposed action, it often protected no one from anything. The adult daughter’s interest and her minor son’s interest in the family trust pointed in exactly the same direction; the law just could not say so.
What section 15804 now says
The rewritten section says so. Where a beneficiary’s interest is substantially identical to that of a person who cannot represent themselves, because they are a minor, incapacitated, not yet born, or their identity or location is unknown and not reasonably ascertainable, the represented person’s interest can be handled through the aligned beneficiary. Notice to the representative is notice to the represented; the representative’s consent or objection binds them both.
The statute carries the family cases on its face: a parent may receive notice for and represent a minor child, and after-born children, where no guardian ad litem has been appointed. And it protects the people relying on it: a trustee who reasonably relies on representation under the section is shielded in that reliance, which is what makes the doctrine usable rather than merely elegant. The bill text and the revised section are on the Legislature’s site under AB 565.
The brake built into it: conflicts
Virtual representation has one governing condition, and everything else depends on it: the interests must actually align. The doctrine’s whole theory is that a person protecting their own position necessarily protects the identical position of the person they represent. The moment the interests diverge, the theory fails, and so does the representation.
That is why the careful practice, in the first year of this statute especially, is conservative. Where alignment is obvious, a current beneficiary standing in for their own minor child with the same remainder interest, the section does its work. Where there is any real argument that the representative gains something the represented person loses, the old machinery is still the right machinery: a guardian ad litem, or instructions from the court. The statute widened the road; it did not remove the guardrails.
What changes in a real administration
For families, the visible difference is fewer proceedings inside the proceeding. An annual accounting no longer waits on a guardian ad litem appointment because one remainder beneficiary is nine years old. A notice of proposed action reaches a complete set of recipients without a court order defining who can receive it for the unborn. Consents that once took a season can close in weeks. The savings are not theoretical; guardian ad litem appointments carry their own fees, and a trust that avoids two or three of them over its life keeps that money working for the beneficiaries.
For trustees, the change is a new decision to document. Every use of section 15804 rests on a judgment that interests are substantially identical, and that judgment belongs in the file: who represented whom, why the interests aligned, and what notice went where. The reliance protection in the statute rewards exactly that kind of record.
What it does not change
The trustee’s duties are untouched. Loyalty, impartiality, the duty to account and to inform: every obligation owed to a represented beneficiary is still owed, in full, whether notice traveled through a representative or not. Virtual representation is a notice-and-consent mechanism, not a discount on fiduciary duty.
It also has nothing to do with conservatorships or guardianships of actual people; despite the shared vocabulary, a guardian ad litem in a trust matter and a guardianship in the California sense are different institutions entirely. And it does not turn contested matters into consent matters. A dispute stays a dispute.
Why this matters to the work of a trustee
Most of a trust administration is not drama; it is notices, accountings, and consents delivered to the right people in the right order. A change that lets those steps clear faster, without shaving anyone’s protections, is the rare reform that helps every honest participant at once. Whether section 15804 applies to a particular matter, and whether interests are truly aligned, is a legal call for a California trust and estates attorney. Running the administration that follows, the notices, the records, the accountings that make reliance defensible, is the work of a trustee, and it is the standard a successor trustee in California is held to from the day they accept the role.
