Most people who become trustees say yes out of loyalty, not legal ambition. A parent trusted you. You were the responsible one. You signed on. But here is what no one mentions at the estate planning table: if you mismanage that trust, California law can reach into your own pocket to make the beneficiaries whole. Not the trust’s pocket. Yours.
For beneficiaries watching assets disappear under a trustee’s watch, that same principle is a powerful legal tool. California gives you real remedies, and this article walks through exactly what they are.
What It Actually Means to Serve as a Trustee in California
A trustee is not just a name on a document. Under California Probate Code section 16000, a trustee must administer the trust according to the trust instrument and, where the instrument is silent, California law fills the gaps. It is a legal office with real legal obligations attached.
Revocable living trusts are the most common estate planning vehicle in Southern California. When the person who created the trust dies or becomes incapacitated, a successor trustee steps in. That person takes on every obligation that comes with the role, whether they fully knew what that meant at the time or not.
What Is a Trustee’s Fiduciary Duty?
California law imposes a fiduciary duty on every trustee — a standard that requires placing the beneficiaries’ interests above all others, including the trustee’s own. The core duties, codified in Probate Code sections 16000 through 16015, include the following.
- Duty of loyalty (§ 16002): Act solely in the interest of the beneficiaries. No conflicts of interest.
- Duty to deal impartially (§ 16003): When there are multiple beneficiaries with competing interests, the trustee must balance them fairly.
- Duty to invest prudently (§ 16047): Manage trust assets as a prudent investor would, weighing risk, return, and the specific needs of the trust.
- Duty to keep property separate (§ 16009): Trust assets must never be commingled with the trustee’s personal funds.
- Duty to keep beneficiaries informed (§ 16060): Beneficiaries have a right to information about the trust and how it is being administered.
- Duty to account (§ 16062): In most circumstances, the trustee must provide a formal accounting to beneficiaries at least once a year.
Any violation of these duties is a breach of trust, and breach is the legal foundation for personal liability.
When Can a Trustee Be Held Personally Liable?
Under Probate Code section 16400, any violation of a duty owed to a beneficiary qualifies as a breach of trust. The list of conduct that can trigger personal liability is longer than most trustees expect.
Self-Dealing
Self-dealing happens when a trustee benefits personally from trust transactions. Selling trust property to themselves at a discount, directing trust business to companies they own, or collecting inflated management fees are all examples. California courts treat self-dealing harshly. The trustee may be required to disgorge every dollar of personal profit, even if the trust itself did not lose money.
Mismanagement of Trust Assets
Reckless investments, ignoring maintenance on trust real estate, or simply doing nothing with trust funds are all forms of mismanagement. Probate Code section 16047 holds trustees to a prudent investor standard that looks at the overall investment strategy. A pattern of negligent decisions opens the door to a surcharge action.
Withholding Required Distributions
When the trust document says a beneficiary receives money at a specific age or under defined conditions, the trustee does not get to override that. Withholding distributions without a legitimate legal basis is a breach of the duty to follow the trust terms. Beneficiaries across San Diego, Orange County, Los Angeles, Riverside, and San Bernardino counties bring these petitions regularly.
Refusing to Account
Under Probate Code section 16062, formal accountings are a legal obligation in most trust administrations. A trustee who refuses to account, submits false records, or stonewalls legitimate questions is not only breaching a statutory duty — that conduct is exactly what probate courts look for when considering removal and surcharge.
Embezzlement and Theft
Under California Penal Code section 503, embezzlement of trust assets is a criminal offense. Theft of more than $950 may be charged as a felony, though it is a wobbler, meaning the prosecutor can charge it as either a felony or a misdemeanor depending on the circumstances and the defendant’s history. A felony conviction can result in up to three years in county jail or state prison, depending on the facts. Theft under $950 is a misdemeanor. On the civil side, a trustee found liable for theft faces a surcharge, removal, and restitution from personal assets.
How Are Damages Calculated?
When a court finds a trustee committed a breach, Probate Code section 16440 governs how liability is measured. The trustee can be charged with:
- Any loss or depreciation in the value of the trust estate caused by the breach, with interest.
- Any profit the trustee personally gained through the breach, with interest.
- Any profit the trust would have earned but for the breach.
This financial penalty is called a surcharge, and it comes from the trustee’s personal assets, not from the trust. There is no corporate shield here. A surcharge judgment reaches the trustee’s own bank accounts, real property, and personal savings.
Separately, Probate Code section 16420 authorizes courts to remove a trustee, compel performance of neglected duties, and appoint a temporary trustee or receiver to take over during litigation.
Good faith matters, but it is not a blanket shield. Under Probate Code section 16440(b), a court has discretion to reduce or excuse a trustee’s liability if the trustee acted both reasonably and in good faith under the circumstances as the trustee knew them, and if doing so would be equitable. That discretion disappears where intentional misconduct, gross negligence, or bad faith is shown.
What About Co-Trustees and Successor Trustees?
Personal liability is not limited to the trustee who directly committed the breach. Under Probate Code section 16402, a co-trustee can face personal liability if they participated in the breach, approved or concealed it, improperly delegated authority, negligently enabled the co-trustee to commit the breach, or failed to take reasonable steps to stop it after learning of it. That category — negligently enables — does not require actual knowledge of the wrongdoing. Inattention alone can be enough.
Successor trustees face their own exposure. Under Probate Code section 16403, a successor who discovers that the prior trustee committed a breach and fails to act can be held personally liable for that inaction. Anyone stepping into a trustee role midway through trust administration should conduct a careful review of prior administration before formally accepting.
The Estate of Giraldin Decision: Revocable Trusts Are Not Off-Limits
Many trustees of revocable trusts assumed that because the settlor could revoke the trust at any time, no one could hold them accountable for what they did while the settlor was alive. In 2012, the California Supreme Court rejected that assumption in Estate of Giraldin, 55 Cal.4th 1058. The court held that remainder beneficiaries — those who inherit after the settlor dies — have standing to pursue a trustee for losses that occurred during the settlor’s lifetime, but only where the trustee acted without the settlor’s knowledge or contrary to the settlor’s wishes. The decision does not allow beneficiaries to relitigate financial choices the settlor knowingly made.
For Southern California families, this matters. Children from prior marriages, grandchildren, and other remainder beneficiaries now have legal standing to demand accountings and pursue damages after the settlor passes, even for events that happened years before.
How Long Does a Beneficiary Have to Sue?
Under Probate Code section 16460, a beneficiary generally has three years from receipt of a trustee’s accounting — or three years from when they knew or reasonably should have known of the breach — to bring a claim. If no accounting was ever provided, the clock may not start at all.
One important exception: under Probate Code section 16461, a trustee who provides an accounting along with the required statutory notice — in 12-point boldface type — can shorten the limitations period to just 180 days. Trustees and beneficiaries alike should know this provision exists. A beneficiary who sits on a received accounting may lose their claim far sooner than they expect.
Key Takeaways
- California trustees owe beneficiaries a fiduciary duty — the highest duty recognized in law — and breaching it opens the door to personal liability.
- The core trustee duties are codified in Probate Code sections 16000 through 16015, and liability for breach is governed by sections 16400 through 16440.
- A court can order a trustee to personally repay losses and forfeit any profits gained through misconduct.
- Co-trustees and successor trustees can face personal liability under specific circumstances.
- The statute of limitations on trust claims can run for years, but it can also be shortened to 180 days if the trustee gives proper statutory notice with an accounting.
Frequently Asked Questions
Can a trustee be sued personally even if they did not steal anything?
Yes. Theft is one basis among many. Poor investment decisions, failing to communicate with beneficiaries, refusing to make required distributions, commingling trust and personal funds, and stonewalling on accountings can all support a personal surcharge action without a dollar being stolen.
What if the trustee genuinely did not know they were breaking the law?
Ignorance of California trust law is not a complete defense. Trustees are presumed to know their legal obligations when they accept the role. That said, under Probate Code section 16440(b), a court has discretion to reduce or excuse liability when a trustee acted both reasonably and in genuine good faith and where granting relief would be equitable. That discretion is unavailable when the conduct involved intentional wrongdoing, gross negligence, or bad faith.
Can the trustee pay their legal fees from trust funds?
This depends on the outcome of the dispute and the specific nature of the claim. Under Probate Code section 17211, a court can award fees against a beneficiary who contests a trustee’s accounting without reasonable cause and in bad faith. That statute does not function as a general prevailing-party fee award for all trust litigation. When a trustee loses a surcharge action, the court can order them to repay any trust funds used for their defense, and they may also be responsible for the opposing party’s attorney fees depending on the circumstances.
Does Probate Code section 18000 protect a trustee from personal liability?
Section 18000 shields a trustee from personal liability on contracts entered into in a representative capacity on behalf of the trust, but only in that specific context. Section 18002 is clear that the trustee remains personally liable for torts committed during trust administration when the trustee was personally at fault. Breach of fiduciary duty, self-dealing, and similar misconduct fall squarely outside section 18000’s protection.
Can I remove a trustee and sue them personally at the same time?
Yes. Under Probate Code section 17200, beneficiaries can petition the probate court to remove a trustee and seek a surcharge in the same proceeding. Courts frequently grant both forms of relief when the record supports it. The probate judge can remove the trustee, appoint a successor or professional fiduciary, and issue a surcharge order requiring the former trustee to repay losses from their personal assets.
What counts as self-dealing?
Self-dealing is any transaction in which the trustee personally benefits — or a close associate of the trustee benefits — at the expense of the trust or its beneficiaries. This includes selling trust property to yourself, purchasing trust assets at below-market prices, paying yourself excessive trustee compensation, lending trust money to relatives at below-market rates, and directing trust business to companies you own or in which you have a financial interest. California courts apply a strict standard: a trustee who profits from a trust transaction must show the transaction was fully disclosed and fair, or face a surcharge.
