The trustee has to look for them, document the search, and then ask the court what to do. What a trustee must not do is quietly divide the missing person’s share among everyone else, which is the shortcut families reach for and the one that creates personal liability.
Does the trustee have to find a missing beneficiary?
Yes, within reason. Prob. Code § 16061.7(d) excuses a trustee from providing the notification to a beneficiary or heir who is known but cannot be located after reasonable diligence, or who is unknown.
Read what that does and doesn’t do. It excuses the notice. It does not extinguish the person’s interest in the trust. Their share still exists and still belongs to them.
What counts as reasonable diligence?
More than a Google search, and the standard is what you can document rather than what you tried. A trustee who has to justify this later wants a file, not a memory.
What a defensible search looks like:
- Last known address, plus mail sent there with return receipt
- Contact with relatives, and a written note of what each said
- Public records: voter rolls, property records, court indexes
- A commercial skip trace or licensed investigator, which is cheap relative to the risk
- The Social Security Death Index, in case the person has died
Keep dates, methods, and results. The point is to be able to hand a judge a chronology.
What if the beneficiary has died?
Then the question changes entirely and becomes one about their estate rather than about finding them. Whether their share passes to their issue, to their own estate, or to the other beneficiaries depends on survivorship and on § 21110.
Our pages on a beneficiary who dies before the settlor and a beneficiary who dies during administration cover both sequences.
Can the trustee just divide the share among everyone else?
No, and this is the mistake to avoid. Absence is not disclaimer. A beneficiary who cannot be found has not given up anything, and a trustee who redistributes their share has distributed to the wrong people.
That exposes the trustee personally. If the missing person appears in four years, the trustee owes them their share, and the money is already gone to beneficiaries who may not return it. See trustee liability after distribution.
What is the safe route?
A petition for instructions under § 17200. A trustee may petition the court concerning the internal affairs of the trust, and asking how to handle an unlocatable beneficiary is squarely within it.
The court can approve the search as diligent, and then authorize an outcome: hold the share, distribute on conditions, or in some circumstances deposit the funds with the county for the missing person to claim. A trustee who follows a court order is protected in a way a trustee acting alone never is.
That protection is the entire point. The petition costs money and it converts an open-ended personal risk into a closed one.
How long should the trustee hold the share?
Only as long as the court says, which is why the petition matters. Holding indefinitely is its own problem: it keeps the trust open, generates ongoing fees and tax returns, and delays every other beneficiary.
If you’re another beneficiary waiting while a trustee sits on an untraceable sibling’s share with no plan, the useful thing to ask for in writing is not the money. It’s the petition. A trustee who won’t search and won’t petition is failing both of you, and that failure is actionable under § 17200 like any other.
