Trust money in a trustee’s personal account is a breach of fiduciary duty on its face. Whether it’s theft, sloppiness, or a bank’s bad advice matters for what happens next, but the starting position is the same: that money doesn’t belong there, and the trustee has to answer for it.
The rule
Prob. Code § 16004(a) says a trustee has a duty not to use or deal with trust property for the trustee’s own profit or for any purpose unconnected with the trust, and not to take part in any transaction in which the trustee has an interest adverse to the beneficiary.
Alongside that sits the duty to keep trust property separate and properly designated as trust property. Commingling defeats the whole point. Once trust money is mixed with personal money, nobody can tell whose dollars paid for what, and the burden of untangling it falls on the trustee, not on you.
Why trustees do it
Assume incompetence before assuming theft. The most common explanations I see:
- The bank wouldn’t open a trust account without a certification of trust and an EIN, so the trustee “temporarily” parked the money in their own account and never fixed it.
- The trustee closed the decedent’s accounts, the bank cut a check payable to them personally, and they deposited it.
- The trustee genuinely believes the money is already theirs because they’re also a beneficiary.
- The trustee is paying trust expenses out of pocket and treating the accounts as interchangeable.
None of these make it acceptable. All of them are fixable if caught early. The last one is the most dangerous, because a trustee who is convinced they’ve done nothing wrong will keep doing it.
What to ask for, in writing
Before accusing anyone, get the record. Under § 16062, the trustee must account at least annually, at termination, and on a change of trustee, to each beneficiary to whom income or principal is required or authorized to be currently distributed.
Ask for the accounting and for the underlying statements. Specifically: which account is the trust account, its statements from the date of death forward, and an explanation for any transfer into a personal account.
Put it in writing and date it. A trustee who refuses to produce statements after a written request has told you something useful.
The remedies
Everything runs through a petition under § 17200. The court can:
- Compel an accounting. Usually the first ask, and often enough on its own. Many trustees who won’t answer a beneficiary will produce records rather than face a judge.
- Surcharge the trustee. Order them to repay what was taken or lost, personally.
- Remove them. § 15642(b)(1) lists breach of trust as a ground for removal.
- Suspend their powers or compel surrender of trust property. § 15642(e) lets the court act before the removal petition is decided, where trust property or a beneficiary’s interest may suffer loss or injury in the meantime. This is the provision that matters when money is actively disappearing.
- Deny or claw back compensation. A trustee who breached doesn’t get paid for breaching.
Where the trustee obtained an advantage in a transaction with a beneficiary, § 16004(c) presumes a violation of fiduciary duty, and the presumption affects the burden of proof. The trustee has to prove the transaction was proper.
Move fast when money is moving
The main practical risk is dissipation. A surcharge order against a trustee who has already spent the money is a piece of paper. If the amounts are large and the trustee is spending, the § 15642(e) suspension route exists precisely for that, and it’s worth the cost of moving quickly.
Signals worth taking seriously: the trustee stops accounting entirely, real property gets refinanced or listed without explanation, distributions stop while the trustee’s own lifestyle doesn’t, or the trustee starts routing communications through a new lawyer and going silent.
When it’s criminal
Misappropriating trust funds can be embezzlement, and elder financial abuse statutes may apply where the victim was an elder or dependent adult. Those cases can carry enhanced remedies including attorney’s fees.
Understand the tradeoff before calling the district attorney. A criminal referral rarely gets the money back, and it will end any chance of a negotiated resolution. In most family cases the civil route recovers more. Where the trustee is a stranger, a professional fiduciary, or someone who has clearly stolen and spent, the calculation changes.
If you’re the trustee who did this
Fix it now, and don’t wait to be caught.
Open a proper trust account with an EIN and a certification of trust. Move the money back, all of it, with a clear paper trail. Reconstruct where every dollar went, honestly, including anything you spent. Tell the beneficiaries in writing what happened and what you’ve done about it. Then get your own lawyer, not the trust’s lawyer.
A trustee who self-corrects and discloses is in a far better position than one whose commingling surfaces in a beneficiary’s petition eighteen months later. Courts distinguish between a trustee who made a mess and a trustee who hid one.
