Can a Trustee Engage in Self-Dealing Under California Law?
Under California law, a trustee generally may not engage in self-dealing unless the trust instrument expressly permits it. The duty of loyalty requires the trustee to administer the trust solely in the best interest of the trust and its beneficiaries. This rule is codified in California Probate Code § 16002, which requires a trustee to act exclusively in the beneficiaries’ best interests.
Self-dealing occurs when a trustee uses trust assets for personal benefit, enters into transactions that benefit them personally, or commingles personal and trust funds. Even seemingly fair transactions may violate fiduciary duties if a conflict of interest arises. California courts presume these transactions are improper unless the trustee proves otherwise.
What Fiduciary Duties Does a Trustee Owe Beneficiaries in California?
Trustees owe multiple fiduciary duties, including the duty of loyalty, the duty of care, and the obligation to manage trust assets prudently. These duties require the trustee to administer the trust in accordance with the trust document and California law, without favoritism toward any beneficiary or the trustee.
The duty of loyalty is reinforced by California Probate Code § 16004, which strictly prohibits trustees from using trust assets for personal gain unless the trust explicitly permits it.
Trustees must also invest and manage trust assets prudently, safeguard trust property, and act in the best interests of the beneficiaries at all times. Failure to do so may constitute a breach of fiduciary duties, even absent intentional misconduct.
Examples of Trustee Conflicts of Interest
A conflict of interest arises when a trustee places their personal interests, or those of a third party, ahead of the beneficiaries’ best interests. Under California law, trustees must avoid situations in which personal gain conflicts with their fiduciary duties, even if no financial harm has yet occurred.
Common examples of trustee conflicts of interest include a trustee purchasing trust property for their own use, lending trust funds to a business they own, or using trust assets for personal benefit without explicit authorization in the trust document. Conflicts may also arise when a trustee favors one beneficiary over others, delays a proper distribution, or enters into transactions that benefit family members or related entities. Under California Probate Code § 16004, transactions involving personal and trust interests are presumed improper unless the trustee can prove the transaction was fair and authorized.
Notably, a conflict of interest does not require intentional misconduct to constitute a breach of fiduciary duty. Even well-meaning trustees can violate their obligations if they fail to avoid conflicts of interest or fully disclose trust transactions to beneficiaries.
Can a Beneficiary Sue a Trustee for Self-Dealing or Misconduct?
Yes. A beneficiary in California has the legal right to sue the trustee for breach of fiduciary duty, including self-dealing, mismanagement of trust assets, or other breaches. Beneficiaries may file a petition in probate court seeking court intervention.
California law provides multiple avenues for legal action, including compelling an accounting, recovering trust assets, or requesting the removal of a trustee. Beneficiaries are entitled to information about the trust under California Probate Code §§ 16060–16063, which requires trustees to keep beneficiaries reasonably informed.
Early engagement of an experienced trust litigation attorney can help protect the trust’s value and prevent further misconduct.
What Remedies Are Available When a Trustee Has Breached Their Fiduciary Duties?
When a trustee has breached their fiduciary duties, California Probate Code § 16420 authorizes the court to impose a wide range of remedies.
Available remedies include ordering the trustee to compensate the trust, voiding improper transactions, restoring trust assets, or imposing equitable relief. In cases involving self-dealing, the trustee may be required to return profits earned from improper trust transactions.
Additionally, under California Probate Code § 16440, trustees may be held personally liable for financial losses caused by their breach of duty.
Trustee removal protects the trust and its beneficiaries from ongoing harm. Courts may also appoint a successor trustee to ensure the trust is managed in accordance with California law and the trust terms.

What Our Amazing Clients Have To Say
Common Trust & Probate Terms
Below are some common terms and helpful definitions used in Trust and Probate. We are here to help educate our clients.
Click on any of the terms below to understand what they mean.
Trust Litigation vs. Probate Litigation
Trust litigation involves legal disputes related to the administration, interpretation, or validity of a trust. These cases typically happen after a trust becomes irrevocable and often involve trustee misconduct, accounting disputes, or challenges based on undue influence.
Probate litigation happens during the probate process and involves disputes over wills, appointment of personal representatives, creditor claims, or asset distribution. While both are handled in probate court, the governing statutes and procedural rules can differ.
Understanding the differences between trust litigation and probate litigation is very important because deadlines, notice requirements, and available solutions vary significantly between trust and probate cases.
Example:
A beneficiary files a trust petition to remove a trustee for breach of duty, while a sibling files a probate petition contesting a will based on lack of capacity.
What is a Beneficiary?
In California trust and probate law, a beneficiary is a person or entity entitled to receive property, income, or other benefits from a trust or estate. Beneficiaries may be specifically named in a trust or will, or they may inherit under California’s intestate succession laws if no valid estate plan exists.
Once a trust becomes irrevocable, California law grants beneficiaries enforceable rights, including the right to receive notice of trust administration, request information, and demand an accounting. Beneficiaries also have legal standing to file petitions in probate court when they believe a trustee or personal representative has breached fiduciary duties.
Statutory References:
Example:
After the settlor’s death, beneficiaries receive a statutory trust notice and later file a petition to compel a trustee accounting.
What is a Trustee?
A trustee is the individual or entity responsible for administering a trust and managing trust assets in accordance with the trust instrument and California law. Trustees act as fiduciaries and must always place the interests of beneficiaries ahead of their own.
California law imposes strict duties on trustees, including the duty of loyalty, duty of care, duty of impartiality, and duty to keep beneficiaries reasonably informed. Alleged violations of these duties are among the most common causes of trust litigation.
Statutory References:
Example:
A trustee who favors one beneficiary over others may be sued for violating the duty of impartiality.
What is a Fiduciary?
A fiduciary is a person or entity legally obligated to act in the best interests of another. In California trust and probate law, fiduciaries commonly include trustees, executors, administrators, and sometimes agents acting under a power of attorney.
Fiduciaries must act with the highest duty of loyalty, honesty, and care. They are prohibited from self-dealing, conflicts of interest, or using estate or trust property for personal benefit.
Breach of fiduciary duty is one of the most common bases for trust and probate litigation in California.
Statutory References:
Example:
A trustee who loans trust funds to themselves without authorization may be sued for breach of fiduciary duty.
What is Probate?
Probate is the court-supervised process used in California to administer a deceased person’s estate when assets are not held in a trust or transferred by non-probate methods.
The probate court oversees the appointment of a personal representative, payment of debts, resolution of disputes, and final asset distribution.
Probate litigation arises when disagreements occur during administration, including will contests, creditor disputes, and challenges to the personal representative’s conduct.
Statutory References:
Example:
Heirs challenge the validity of a will during probate, delaying distribution of estate assets.
What is Intestate Succession?
An intestate estate occurs in California when a person dies without a valid will or trust that disposes of their probate assets. When this happens, California’s intestate succession laws determine who inherits the decedent’s property and in what proportions, regardless of the decedent’s informal wishes or family expectations.
Intestate estates are administered through probate court, and the court appoints an administrator to manage the estate.
Distribution is strictly controlled by statute, prioritizing spouses, children, and other relatives in a defined order. Intestate estates frequently lead to probate litigation in California when heirs dispute heirship, asset classification, or administrator conduct.
Statutory References:
Example:
A decedent dies without a will, and multiple relatives file competing petitions in probate court to determine heirship and appoint an administrator.
What is Undue Influence?
Undue influence under California law occurs when excessive persuasion overcomes a person’s free will and results in an inequitable outcome, particularly in connection with a will or trust. Courts evaluate factors such as vulnerability, authority, tactics used, and the resulting benefit.
California law also establishes a presumption of undue influence when certain individuals, such as caregivers or fiduciaries, receive disproportionate benefits under estate planning documents.
Statutory References:
Example:
A caregiver who drafts trust amendments and receives most of the estate may trigger a statutory presumption of undue influence.
What is a Trust Notice?
A Trust Notice is a mandatory written notice that must be served when a revocable trust becomes irrevocable, most often after the settlor’s death.
A trust notice informs beneficiaries and heirs of the trust’s existence and their rights.
This notice is legally significant because it triggers the deadline for filing a trust contest. If proper notice is not served, the statute of limitations may be extended.
Statutory Reference:
Example:
A successor trustee sends notice within 60 days, starting the 120-day period to challenge the trust.
What is a Will Contest?
A will contest is a legal challenge filed in California probate court disputing the validity of a will. Grounds include lack of testamentary capacity, undue influence, fraud, duress, or improper execution.
Contesting a Will must comply with strict filing deadlines and procedural requirements, making early legal action critical.
Statutory References:
Example:
An heir contests a will signed shortly before death, alleging lack of mental capacity.
Trustee vs. Executor
A trustee manages and administers assets held in a trust, while an executor (a type of personal representative) administers assets that are subject to probate under a person's will. Although both roles involve fiduciary responsibilities, they operate under different California laws.
Trustees generally act outside of ongoing court supervision unless a dispute occurs, whereas executors operate within the probate court system from the outset.
This distinction often determines whether a dispute is classified as trust litigation or probate litigation.
Example:
A trustee is sued for mismanaging trust investments, while an executor is challenged in probate court for improper estate distributions.
