Trustee Self-Dealing in California: What the Law Prohibits and What Beneficiaries Can Do
Last updated October 9, 2026
The problem
California Probate Code section 16004 bars trustees from profiting from trust property. Learn the presumption, the remedies, removal grounds and the three-year rule.
Trustee self-dealing is when a California trustee uses trust property for personal gain, or takes part in a deal where the trustee's own interest runs against the beneficiaries'. Selling a trust house to oneself, lending trust money to one's own business, or quietly raising one's own pay can all qualify. California Probate Code section 16004 prohibits it.
Most people facing this question have noticed something that does not sit right. A sibling serving as trustee has moved into the family home without paying rent, or a brokerage statement shows a transfer to an account nobody recognizes, or the trustee's fee seems to have grown while the trust has not. Sometimes the person searching is the trustee, newly accused of a conflict of interest by a brother, sister or co-trustee, and trying to understand what the accusation actually means. Either way, the reader wants to know where California draws the line between a trustee doing the job and a trustee helping themselves, and what the law allows each side to do about it.
This page walks through the statutory rule, the presumption that can shift the burden to the trustee, the forms self-dealing tends to take, the trustee's duties to inform and account, the remedies a court may order, removal, and the time limit for bringing a claim.
What Trustee Self-Dealing Means Under California Law
California Probate Code section 16004(a) states the rule directly: "The trustee has a duty not to use or deal with trust property for the trustee's own profit or for any other purpose unconnected with the trust, nor to take part in any transaction in which the trustee has an interest adverse to the beneficiary."
That sentence is one expression of what lawyers call the duty of loyalty: the trustee's obligation to put the beneficiaries first and to keep the trustee's own interests out of the trust's business. A companion statute, Probate Code section 16002(a), says the trustee "has a duty to administer the trust solely in the interest of the beneficiaries." Self-dealing is the most common way that duty gets broken.
In California this is a written statutory duty, set out in the Probate Code, not just a tradition of judge-made law. That matters in practice, because a beneficiary or trustee can point to the exact words a court will apply.
The rule has two parts. The first bars a trustee from using trust property for personal profit or for any purpose unconnected with the trust. The second is broader: it bars the trustee from taking part in any transaction in which the trustee has an interest adverse to the beneficiary. The second part reaches deals where the benefit is less direct. A sale of trust real estate to a company the trustee owns, or a contract steering trust work to a business run by the trustee's spouse or child, may involve exactly that kind of competing interest, even when the trustee's own name never appears on the paperwork.
Self-dealing is different from an honest mistake. A trustee who makes a poor investment, misses a tax deadline or sells a stock at the wrong time may have mismanaged the trust, but those are problems of care and judgment. Self-dealing is about whose side the trustee was on. The question is not only whether the trust lost money but whether the trustee stood to gain, directly or through someone close, from a decision made with trust property.
The Presumption That Arises When a Trustee Obtains an Advantage
Probate Code section 16004(c) adds a procedural rule that often decides how a self-dealing dispute unfolds. A transaction between the trustee and a beneficiary, occurring during the existence of the trust or while the trustee's influence with the beneficiary remains, "by which the trustee obtains an advantage from the beneficiary is presumed to be a violation of the trustee's fiduciary duties."
The statute calls this "a presumption affecting the burden of proof." In plain words, a presumption affecting the burden of proof means the law starts from the assumption that the transaction was improper, and the trustee carries the burden of proving otherwise. Once the beneficiary shows a transaction with the trustee in which the trustee came out ahead, the beneficiary does not have to prove bad intent. The trustee has to show the deal was fair.
This presumption has a specific trigger. It concerns transactions between the trustee and a beneficiary, such as a trustee buying a beneficiary's share of a family property at a low price, or obtaining a beneficiary's signature on a release in exchange for something worth less than what was given up. It does not apply to "the provisions of an agreement between a trustee and a beneficiary relating to the hiring or compensation of the trustee." A dispute over what a trustee is paid is handled under the compensation rules discussed below, not under this presumption.
A different presumption sometimes comes up in the same family disputes and is easy to confuse with this one. Probate Code section 21380 concerns instruments that make a donative transfer, meaning a gift in a will, trust or similar document, to certain people, including the person who drafted the instrument. Such a provision is presumed to be the product of fraud or undue influence. That rule is about whether a gift in the document itself is valid, the kind of question raised in contesting a trust in California. It has its own rules about how the presumption is overcome. Section 16004(c), by contrast, is about how the trustee behaves while running the trust. A single family dispute can involve both, but they are separate claims with separate proof.
Common Forms of Self-Dealing in California Trust Administration
Self-dealing tends to show up in a handful of recognizable patterns. Each one connects back to the text of section 16004(a).
Buying trust property. A trustee who purchases a trust asset, such as the family house, a rental property, a vehicle or a share of a business, is dealing with trust property in a transaction where the trustee's interest as buyer runs against the beneficiaries' interest in a full price. A purchase below market value is the clearest example, but the conflict exists even when the trustee believes the price was fair.
Lending trust money to oneself. Loans from the trust to the trustee, or to a company the trustee owns or controls, use trust property for something other than the trust's own purposes. Whether the loan was repaid, or carried interest, does not erase the conflict.
Steering trust business. Hiring a property manager, contractor, broker or other service provider in which the trustee has a financial stake places the trustee on both sides of the bargain.
Overpaying oneself. Under Probate Code section 15681, if the trust instrument does not set the trustee's compensation, "the trustee is entitled to reasonable compensation under the circumstances." A trustee who pays themselves more than the instrument authorizes, or more than reasonable compensation where the instrument is silent, is taking trust money for personal benefit.
Raising a fee without notice. Probate Code section 15686(b) bars a trustee from charging an increased trustee's fee unless the trustee first gives at least 60 days' written notice to each beneficiary entitled to an account under section 16062, each beneficiary given the last preceding account, and each beneficiary who has asked in writing for notice of fee increases and given an address. The term "trustee's fee" includes the periodic base fee, percentage rate, minimum fee, hourly rate and transaction charges, but not fees for extraordinary services. Under section 15686(c), if a beneficiary files a petition under section 17200 to review the increase or to remove the trustee, and serves it on the trustee before the 60 days run out, the increase does not take effect until the court orders otherwise or the petition is dismissed.
Some trust instruments expressly allow a trustee to do things that would otherwise raise a conflict, such as buying a particular asset or serving as manager of a family business. When a beneficiary believes a transaction went beyond what the instrument allows, or that the trustee used a permission in a way that did not serve the beneficiaries, a court can decide those questions. Section 17200(b) lists proceedings to determine the existence or nonexistence of any power or duty and to pass upon the acts of the trustee, including the exercise of discretionary powers.
For a beneficiary looking at a single suspicious transaction, the pattern it fits often matters less than the documents behind it: who signed, who was paid, and what the trust received in return.
The Trustee's Duty to Inform and Account
Self-dealing usually comes to light through information, and California gives beneficiaries specific rights to it.
Keeping beneficiaries informed. Probate Code section 16060 provides that "the trustee has a duty to keep the beneficiaries of the trust reasonably informed of the trust and its administration."
Answering requests. Under Probate Code section 16061, except as section 16069 provides, the trustee must, on reasonable request by a beneficiary, provide "requested information to the beneficiary relating to the administration of the trust relevant to the beneficiary's interest."
Accounting. Probate Code section 16062(a) requires the trustee to account at least annually, at the termination of the trust, and upon a change of trustee. That duty runs to each beneficiary to whom income or principal is required or authorized in the trustee's discretion to be currently distributed. Not every beneficiary is owed an annual account; a beneficiary whose interest begins only later may fall outside the rule. Section 16062 also contains exceptions, including for certain trusts created by instruments executed before July 1, 1987, and section 16064 lists further situations in which the account is not required.
Waivers that do not end the matter. Under section 16064, a trust instrument may waive the account, and a beneficiary may waive it in writing. But regardless of either kind of waiver, "upon a showing that it is reasonably likely that a material breach of the trust has occurred, the court may compel the trustee to account." Section 16062(e) also voids a waiver of accounting as to a sole trustee described in subdivision (a) of section 21380, unless an exception in section 21382 applies.
These duties matter for self-dealing in a particular way. A trustee who leaves a self-dealing transaction out of an account, or describes it so vaguely that a reader cannot tell what happened, is not only keeping a secret. Failing to keep beneficiaries reasonably informed is a separate breach layered on top of the original one.
Petitions to compel. When requests go unanswered, Probate Code section 17200(b)(7) allows a petition asking the court to compel the trustee to provide a copy of the terms of the trust, to provide information under section 16061, or to account. A petition to compel information is available if the trustee has failed to provide it within 60 days after the beneficiary's reasonable written request, and the beneficiary has not received the requested information within the six months preceding the request. A petition to compel an account, subject to section 16064, is available if the trustee has failed to submit a requested account within 60 days after written request and no account has been made within six months preceding the request. The details of that petition are covered in the page on a Probate Code 17200 petition.
Remedies Available to Beneficiaries Under California Law
Probate Code section 17200(a) gives a trustee or beneficiary the right, except as section 15800 provides, to petition the court "concerning the internal affairs of the trust or to determine the existence of the trust." These petitions are heard by the Superior Court of California for the appropriate county. The proceedings listed in section 17200(b) include, but are not limited to, compelling redress of a breach of the trust by any available remedy, settling accounts and passing upon the trustee's acts, reviewing the reasonableness of the trustee's compensation, and appointing or removing a trustee.
Probate Code section 16420(a) sets out what a beneficiary or cotrustee may ask for when a trustee commits, or threatens to commit, a breach of trust. The proceeding may be brought for any of these purposes that is appropriate:
- to compel the trustee to perform the trustee's duties;
- to enjoin the trustee from committing a breach of trust;
- to compel the trustee to redress a breach of trust by payment of money or otherwise;
- to appoint a receiver or temporary trustee to take possession of the trust property and administer the trust;
- to remove the trustee;
- subject to section 18100, to set aside acts of the trustee;
- to reduce or deny compensation of the trustee;
- subject to section 18100, to impose an equitable lien or a constructive trust on trust property; and
- subject to section 18100, to trace trust property that has been wrongfully disposed of and recover the property or its proceeds.
A constructive trust is a court order treating property as held for the rightful owner, so that an asset taken from the trust is ordered returned rather than merely paid for. Section 16420(b) adds that these remedies do not prevent resort to "any other appropriate remedy provided by statute or the common law."
Surcharge. A money judgment against a trustee for breach is often called a surcharge. Under Probate Code section 16440(a), a trustee who commits a breach of trust is chargeable with whichever of the following is appropriate under the circumstances: any loss or depreciation in value of the trust estate resulting from the breach, with interest; any profit the trustee made through the breach, with interest; or any profit that would have accrued to the trust estate if the loss of profit resulted from the breach. The second option matters for self-dealing, because a trustee can be made to give up a personal profit even when the trust itself appears to have lost little.
A surcharge is not automatic. Section 16440(b) provides that if the trustee "acted reasonably and in good faith under the circumstances as known to the trustee," the court, in its discretion, may excuse the trustee in whole or in part if it would be equitable to do so. A trustee accused of self-dealing will often rely on this provision, and a court weighs it on the facts.
Twice the value under section 859. Probate Code section 859 applies when a court finds that a person has in bad faith wrongfully taken, concealed or disposed of property belonging to a trust (among other protected estates), or has taken, concealed or disposed of the property by the use of undue influence in bad faith or through the commission of elder or dependent adult financial abuse as defined in California's Welfare and Institutions Code. A person the court finds liable on one of those grounds is liable for twice the value of the property recovered by an action under that part of the Probate Code. In addition, except as otherwise required by law, the person may, in the court's discretion, be liable for reasonable attorney's fees and costs. Nothing in section 859 happens without that finding, and the fee award remains discretionary even when it is made. These remedies are in addition to any others available by law. An overview of how these claims fit together appears on the page about California trust litigation.
Orders while the case is pending. Probate Code section 17206 allows the court, in its discretion, to "make any orders and take any other action necessary or proper to dispose of the matters presented by the petition, including appointment of a temporary trustee to administer the trust in whole or in part."
For a family member who has watched a parent's savings or house pass through a trustee's hands, it can help to know that the law looks at both what the trust lost and what the trustee gained.
Removal of a Trustee for Self-Dealing
Probate Code section 15642(a) provides that a trustee may be removed in accordance with the trust instrument, by the court on its own motion, or on petition of a settlor, cotrustee or beneficiary under section 17200. The settlor is the person who created the trust.
Section 15642(b) lists grounds for removal by the court. They include:
- where the trustee has committed a breach of the trust;
- where the trustee is insolvent or otherwise unfit to administer the trust;
- where hostility or lack of cooperation among cotrustees impairs the administration of the trust;
- where the trustee fails or declines to act;
- where the trustee's compensation is excessive under the circumstances; and
- where the sole trustee is a person described in subdivision (a) of section 21380, subject to the conditions and exceptions that paragraph sets out.
The statute says the grounds "include" these, so the list is not a complete catalog of every reason a court may consider.
Self-dealing that amounts to a breach of trust falls within the first ground. An excessive fee may also fall within the fifth. When co-trustees are at odds over an accusation of self-dealing, the third ground can come into play as well.
The statute uses the word "may." A court that finds a breach still decides whether removal is the appropriate response, looking at the trust, the beneficiaries and the circumstances. A court might instead order an accounting, set aside a transaction, reduce compensation or order repayment, alone or together with removal. A trustee facing a removal petition typically responds to the specific conduct alleged, and the outcome depends on the evidence.
While a removal petition is pending, section 17206 permits the court to appoint a temporary trustee to administer the trust in whole or in part, and section 16420(a) separately lists appointment of a receiver or temporary trustee among the remedies for a breach or threatened breach.
The Statute of Limitations for Self-Dealing Claims
Probate Code section 16460(a) sets the time limit for a breach-of-trust claim, and it has two branches. Which one applies depends on what the beneficiary received.
Branch one: an account or report that discloses the claim. If a beneficiary has received an interim or final account in writing, or other written report, that adequately discloses the existence of a claim against the trustee for breach of trust, the claim is barred as to that beneficiary unless a proceeding is commenced within three years after receipt of the account or report. The statute explains that an account or report adequately discloses a claim "if it provides sufficient information so that the beneficiary knows of the claim or reasonably should have inquired into the existence of the claim."
Branch two: no adequate disclosure, or nothing received. If no written account or report adequately discloses the claim, or the beneficiary does not receive any written account or report, the claim is barred unless a proceeding is commenced within three years after the beneficiary discovered, or reasonably should have discovered, the subject of the claim.
Both branches open with an important qualifier: the rule applies unless the claim is already barred "by adjudication, consent, limitation, or otherwise." A prior court order or a signed release, for instance, can raise separate questions.
Section 16460(b) also addresses who counts as receiving an account. For an adult reasonably capable of understanding it, the account must reach that adult personally. For an adult who is not, receipt by a legal representative counts. For a minor, receipt by the minor's guardian, or by a parent without a conflict of interest if there is no guardian, counts.
Concealment bears directly on which branch applies. An account that lists a sale of trust property to the trustee by name and price likely starts the first branch. An account that buries the same sale in a vague entry, or omits it, may not adequately disclose anything, which can move the claim to the second branch and the question of when the beneficiary discovered or reasonably should have discovered the subject of the claim. Whether a given account was adequate is a factual question, and it is often one of the first issues argued in a self-dealing case.
Talking Through a Possible Self-Dealing Dispute
Self-dealing claims turn on details that are easy to misread from the outside: what the trust instrument permits, what each account actually disclosed and when it arrived, who benefited from a transaction, and which of the two limitation branches applies. A consultation about a dispute like this typically centers on the trust instrument and any amendments, the accounts and reports the trustee has provided, written requests and responses, deeds, loan records and fee notices, and the dates attached to each. This page is written for people in a dispute or close to one; a reader who simply wants to understand an ordinary, uncontested trust administration may find a different first call more useful.

Frequently asked questions
What is trustee self-dealing under California law?
Trustee self-dealing is a trustee using trust property for personal profit, or taking part in a transaction where the trustee's own interest is adverse to the beneficiary's, both of which California Probate Code section 16004(a) prohibits. It is a breach of the duty of loyalty, the trustee's obligation to act solely in the beneficiaries' interest under section 16002(a).
What are the responsibilities and duties of a trustee?
The duties most relevant to self-dealing include the duty of loyalty under Probate Code sections 16002 and 16004, the duty to keep beneficiaries reasonably informed under section 16060, the duty to provide requested information under section 16061, and the duty to account under section 16062 to beneficiaries entitled to current distributions. That is a partial list; the Probate Code imposes other duties as well.
What happens when a trustee is caught self-dealing?
A beneficiary or cotrustee may ask the court for the remedies Probate Code section 16420(a) lists, including an order compelling repayment, removal of the trustee, a constructive trust, reduced or denied compensation, and setting aside the trustee's acts. Under section 16440(a) a trustee may be charged with the trust's loss or the trustee's own profit, with interest. None of this is automatic: section 16440(b) lets the court excuse a trustee who acted reasonably and in good faith, in whole or in part, if that would be equitable.
Can a trustee buy trust property for themselves in California?
Buying trust property for oneself is a classic example of the conflict Probate Code section 16004(a) prohibits, because the trustee is dealing with trust property in a transaction where the trustee's interest as buyer is adverse to the beneficiaries'. Some trust instruments grant specific permissions, and whether a purchase fell within them is a question a court can decide on a section 17200 petition. If the trustee obtained an advantage from a beneficiary in the deal, section 16004(c) presumes a breach of fiduciary duty.
How do I prove a trustee is self-dealing?
Proof often starts with documents, and California law offers ways to obtain them. A beneficiary entitled to an account may request one under Probate Code section 16062, and a beneficiary may request information under section 16061; if the trustee does not respond within 60 days of a written request, and nothing was provided in the prior six months, section 17200(b)(7) allows a petition to compel. Where the transaction was between the trustee and a beneficiary and gave the trustee an advantage, section 16004(c) places the burden on the trustee to show it was proper.
Can a trustee be removed for self-dealing in California?
Yes, a trustee can be removed for self-dealing that amounts to a breach of trust, which is one of the grounds Probate Code section 15642(b) lists. Removal may be sought by petition under section 17200, and the court decides whether removal is appropriate rather than ordering it automatically. Under section 17206, the court may appoint a temporary trustee while the petition is pending.
How long does a beneficiary have to bring a self-dealing claim?
Under Probate Code section 16460(a), the period is three years, and it runs from one of two starting points. If the beneficiary received a written account or report that adequately disclosed the claim, the three years run from receipt. If no account or report adequately disclosed it, or none was received, the three years run from when the beneficiary discovered, or reasonably should have discovered, the subject of the claim.
Who cannot be a trustee in California?
The Probate Code sections discussed here do not set out a general list of people barred from serving; they address when a serving trustee may be removed. Under Probate Code section 15642(b), grounds for removal include a trustee who is insolvent or otherwise unfit to administer the trust, and, subject to stated exceptions, a sole trustee who is a person described in section 21380(a), such as the person who drafted the instrument.
