Understanding Breach of Fiduciary Duty in Trust Administration

Your parent passed away months ago. You know a trust exists. The family home, savings accounts, and investment portfolio were supposed to be protected and distributed according to your loved one’s wishes. Instead, the trustee keeps putting you off. Statements you requested never arrive. The home may have been sold below market value to someone close to the trustee. When you finally get answers, the explanations do not add up.

What you are describing is not just a difficult family situation. Under California law, it may be a serious violation known as a breach of fiduciary duty, and the Probate Code gives beneficiaries enforceable rights to address it.

What is a Trustee’s Fiduciary Duty?

A trustee is not just a manager. Under California law, a trustee holds one of the most demanding legal roles that exists: a fiduciary. That word carries significant weight. A fiduciary must, by law, place the interests of the beneficiaries ahead of their own, unless the trust instrument, a court order, or beneficiary consent allows otherwise.

California’s Probate Code, Sections 16000 through 16015, lays out the core duties every trustee must follow:

Duty of loyalty (Probate Code §16002). The trustee must act solely in the interest of the beneficiaries. Using their position for personal gain is prohibited unless properly authorized or fully disclosed and consented to under applicable law.

Duty of care (Probate Code §16040). Trust assets must be managed with the same reasonable skill, prudence, and caution that a prudent person would use in managing their own property.

Duty of impartiality (Probate Code §16003). When there are multiple beneficiaries, the trustee cannot improperly favor one beneficiary over another. Each beneficiary’s interests must be considered and administered fairly in accordance with the terms of the trust.

Duty to keep beneficiaries informed (Probate Code §§16060–16061). Beneficiaries have a legal right to be kept reasonably informed about the trust and its administration, including the right to request relevant information.

Duty to account (Probate Code §16062). Trustees are required to provide accountings as required by the terms of the trust and California law, generally at least annually in many continuing trusts, unless waived or modified by the trust instrument or agreement of the beneficiaries. These accountings must include relevant financial activity, income, expenses, and trust assets.

These are not guidelines. They are binding legal obligations. When a trustee violates any of them, California courts have authority to intervene upon a petition by an interested party.

What Does a Breach of Fiduciary Duty Actually Look Like?

Trustee misconduct can be as blatant as outright theft, or as subtle as a pattern of unresponsiveness and delay. Here are the forms that appear most often in California probate courts. 

Self-Dealing

Self-dealing is among the most serious violations a trustee can commit. It happens when a trustee uses their position to benefit themselves, a family member, or a related party at the expense of the trust. Probate Code §16004 generally prohibits a trustee from entering into transactions that involve a conflict of interest unless the transaction is authorized by the trust, approved by the court, or consented to by the beneficiaries after full disclosure.

This can include purchasing trust property at an unfair price, making personal loans from trust funds, or hiring businesses owned by the trustee or their relatives on unfavorable terms to the trust. Under Probate Code §16004(c), transactions between a trustee and a beneficiary are presumed to be the result of undue influence and are subject to close court scrutiny. The burden is on the trustee to prove the transaction was fair and properly authorized.

Failure To Distribute

Most trusts contain clear instructions about when and how assets should be distributed. When a trustee unreasonably delays distributions, ignores those instructions, or withholds funds without a valid administrative reason, that conduct can constitute a breach of fiduciary duty.

In some cases, delay may be tied to compensation structures, since trustees may be entitled to reasonable compensation based in part on trust administration. Under Probate Code §15680, however, trustee compensation must be reasonable and is governed by the trust document or, if disputed, court review. A trustee cannot justify unnecessary delay in distributions solely to extend fees or administration.

Commingling Assets

Trust property must be kept separate from the trustee’s personal assets. Probate Code §16009 requires trustees to properly safeguard and segregate trust property.

Commingling occurs when trust funds are mixed with personal funds. This can make it difficult to determine what belongs to the trust and may raise serious concerns about mismanagement or misuse of assets.

Failure To Account And Communicate

A trustee who refuses to provide accountings, ignores reasonable requests for information, or produces incomplete financial records may be violating Probate Code §§16060–16061 and §16062.

Beneficiaries have a legal right to information reasonably necessary to enforce their interests and to understand how the trust is being administered. Lack of transparency is often a key warning sign that something may be wrong in the administration of the trust.

Imprudent Investments

California follows the Uniform Prudent Investor Act (Probate Code §16045 et seq.), which requires trustees to invest and manage trust assets with reasonable care, skill, and caution based on the purposes of the trust, its terms, and the needs of the beneficiaries.

This standard focuses on overall portfolio management rather than individual investment performance. Conduct that may violate this duty includes failing to diversify investments when appropriate, concentrating assets in overly risky or speculative holdings, or allowing assets to remain uninvested in a way that is inconsistent with the trust’s objectives. Each situation is evaluated based on the specific circumstances of the trust.

What Can You Do If You Suspect A Breach? 

California law gives beneficiaries several meaningful legal tools. Knowing which ones apply to your situation is the first step.

Demand An Accounting 

Under Probate Code §§16060–16061 and §16062, beneficiaries have the right to request information about the trust and, in many cases, a formal accounting depending on the nature of the trust and the circumstances of administration.

If a trustee refuses to provide required information or accountings, or provides records that are incomplete or unclear, that refusal may support a claim for breach of fiduciary duty and may justify court intervention.

Petition The Probate Court

Under Probate Code §17200, beneficiaries can petition the court to review and intervene in trust administration. This can include requests to compel an accounting, interpret trust terms, require compliance with fiduciary duties, or address concerns about trustee conduct.

Seek Trustee Removal

Under Probate Code §15642, a court may remove a trustee who has committed a breach of trust, is unfit to administer the trust, has failed to act, has become insolvent, or whose removal is otherwise in the best interests of the beneficiaries.

Removal is a discretionary remedy based on the facts of each case and the court’s assessment of the trustee’s conduct.

Seek Surcharge Damages

Under Probate Code §§16420–16440, a trustee who breaches fiduciary duties may be held personally liable for losses caused to the trust. This can include repayment of lost trust value, interest, and any profits the trustee improperly obtained as a result of the breach.

The purpose of surcharge is to restore the trust to the position it would have been in if the breach had not occurred.

Pursue Double Damages

Under Probate Code §859, when a trustee is found to have taken, concealed, or disposed of trust property in bad faith, the court may order the trustee to pay twice the value of the property involved, along with attorney’s fees.

This remedy is typically applied in cases involving intentional misconduct, theft, or concealment of assets, and requires a specific finding of bad faith.

How Long Do You Have to Act?

The statute of limitations for breach of fiduciary duty claims in California trust matters is not one-size-fits-all, and the timing depends on the nature of the claim and when the breach was discovered. 

In general, different limitation periods may apply: 

Four-year period (Code of Civil Procedure §343). Often applies to breach of fiduciary duty claims and runs from the date the beneficiary discovered, or reasonably should have discovered, the breach.

Three-year period (Code of Civil Procedure §338(d)). Applies to claims involving fraud or intentional concealment, also subject to the discovery rule.

Three-year rule tied to accountings (Probate Code §16460). When a trustee provides a proper accounting that discloses relevant facts, a three-year period may apply to claims based on matters disclosed in that accounting.

The discovery rule also plays an important role in trust disputes. It means:

  • The clock may not begin until the beneficiary discovers, or reasonably should have discovered, the breach
  • If a trustee withholds information or fails to provide required accountings, the start of the limitations period may be delayed

This is why timing matters in trust disputes. Delay can narrow your legal options and, in some cases, prevent recovery altogether.

Key Takeaways

  • California trustees are held to a strict fiduciary standard under California law. Core duties include loyalty, impartiality, prudent care, and transparency under Probate Code §§16002, 16003, 16040, and §§16060–16061.
  • Common breaches include self-dealing, failure to make required distributions, commingling trust assets with personal funds (§16009), failure to provide required account information or accountings (§16062), and imprudent investment decisions under the Uniform Prudent Investor Act (§16045 et seq.).
  • Beneficiaries have several legal remedies available depending on the facts of the case, including trustee removal (§15642), surcharge liability for losses caused by breach of duty (§16420–16440), and in cases involving bad faith conduct such as wrongful taking or concealment of trust property, potential exposure to double damages (§859).
  • The time to bring a claim depends on the nature of the breach. In many cases, limitation periods range from three to four years from discovery, but timing may be affected by disclosures in accountings under §16460 and delayed discovery where information was concealed or withheld.
  • Prompt action helps preserve legal options. Delay can limit available remedies and, in some cases, prevent recovery of trust assets altogether.

Frequently Asked Questions

How do I know if my trustee is actually breaching their duties, or just being slow?

There is a difference between normal administrative delay and a potential breach of fiduciary duty. Warning signs include unexplained or prolonged delays in distributions, failure to provide required account information or accountings, inconsistent explanations about trust assets, transactions that appear to benefit the trustee personally, and assets that cannot be properly accounted for. Not every delay is misconduct, but lack of transparency may justify further review. 

Can a family member who serves as trustee be held liable?

Yes. Family members serving as trustees are held to the same fiduciary standards as professional or corporate trustees under California law. If they breach their duties and cause harm, they can be held personally liable. 

What if the trustee already transferred or spent the assets?

Legal remedies may still be available. Courts can issue orders to preserve assets during litigation when appropriate. If assets have already been moved or spent, beneficiaries may still pursue recovery through surcharge claims and tracing methods such as forensic accounting. Acting quickly improves the likelihood of recovery. 

Will I have to pay attorney’s fees out of pocket?

Not necessarily. In cases involving bad faith misconduct, Probate Code §859 may allow the court to order the trustee to pay attorney’s fees. Courts may also award fees from the trust when litigation is necessary to protect trust assets. 

What is the difference between a civil claim and a criminal matter?

Most trustee misconduct cases are civil and handled in probate court, focused on recovering assets and enforcing fiduciary duties. However, conduct involving theft, fraud, or embezzlement may also result in criminal charges under California law. Civil and criminal cases can proceed separately. 

Your Loved One’s Trust Deserves To Be Honored

If you believe a trustee has violated their fiduciary duties, whether through self-dealing, refusal to provide accountings, suspicious transfers, or other conduct that does not seem right, do not wait. Every day that passes without action can make recovery more difficult.
