Successor Trustee Disputes in California
Last updated October 9, 2026
The issue in brief
How California successor trustee disputes work: the duties owed, when a court may compel an account or remove a trustee, and the 120-day/60-day contest rule.
A successor trustee dispute in California is a conflict over how the person who took over a trust is handling it. Beneficiaries and co-trustees can ask the Superior Court to compel information or an accounting, stop a breach, surcharge the trustee, or remove the trustee when the Probate Code's grounds are met.
Most people facing a successor trustee dispute did not expect one. A parent has died, and a sibling, a stepparent or a family friend now controls the house, the accounts and the timetable. Months may have passed without a statement, a copy of the trust, or a straight answer about when anything will be distributed. Sometimes the reader is the trustee, accused of hiding things while doing the slow, unglamorous work the role requires. Either way, the question is the same: what does California law actually require of this person, and what can a court do about it?
This page walks through the role, the duties, co-trustee deadlock, removal, compelling information and accounts, the notification and contest deadlines, and the presumptions that can shift the burden of proof.
What a Successor Trustee Is and When Disputes Arise
A successor trustee is the person or institution named in the trust instrument to take over management of the trust when the original trustee dies, resigns or becomes incapacitated. The settlor, the person who created the trust, is often the first trustee of a living trust. When the settlor can no longer serve, the successor steps in.
A co-trustee is different. Co-trustees serve at the same time and share the office. A successor trustee serves in sequence, after someone else. A trust can have both: two siblings named to serve together as successor co-trustees, for example. If the trust names no one, or the named person cannot serve, Probate Code section 15660 says the vacancy is filled the way the trust instrument provides, and failing that, in certain cases by a trust company with the agreement of the adult beneficiaries the statute describes.
The death of a settlor is the moment many disputes begin. When a revocable trust becomes irrevocable because a settlor has died, Probate Code section 16061.7(a) requires the trustee to serve a written notification on the people the statute describes. That is one of several events that trigger the requirement, not the only one.
The disputes that follow tend to fall into familiar categories, including:
- Alleged breach of fiduciary duty, meaning the trustee failed to meet a legal duty owed to the beneficiaries.
- Failure to account, where a trustee will not report what came in, what went out and what remains.
- Self-dealing, where the trustee uses trust property for personal benefit, such as living in a trust-owned house rent-free or buying trust property cheaply.
- Co-trustee deadlock, where two trustees cannot agree and the trust stalls.
- Removal petitions, where a beneficiary or co-trustee asks the court to replace the trustee.
Under Probate Code section 17200(a), a trustee or beneficiary may, with limited exceptions, petition the court concerning the internal affairs of a trust or to determine whether a trust exists. In California, that petition is heard by the Superior Court of California for the relevant county, in its probate department. The broader picture of how these cases move is set out on the California trust litigation attorney page.
Duties a Successor Trustee Owes Under California Law
The trustee has a duty to keep the beneficiaries reasonably informed of the trust and its administration (Probate Code section 16060). That is the baseline. A trustee who goes silent for a year is not meeting it, though "reasonably informed" is not the same as answering every email the same day.
On top of that general duty, Probate Code section 16061 requires the trustee, on a beneficiary's reasonable request, to provide requested information about the trust's administration that is relevant to that beneficiary's interest, except as section 16069 provides.
The duty to account is narrower than many beneficiaries assume. Under Probate Code section 16062, the trustee must account at least annually, at the termination of the trust and upon a change of trustee, but only to each beneficiary to whom income or principal is required, or authorized in the trustee's discretion, to be currently distributed, and subject to the exceptions in sections 16062 and 16064. A remainder beneficiary who receives nothing until a surviving spouse dies may not be owed an annual account under that section. Section 16062 also exempts certain older trusts, such as a living trust created by an instrument executed before July 1, 1987.
Waivers have limits. Under Probate Code section 16064, a trust instrument may waive the account, and a beneficiary may waive it in writing, but in either case the court may compel the trustee to account upon a showing that it is reasonably likely that a material breach of the trust has occurred.
The duty of loyalty sits at the center of most serious disputes. Probate Code section 16004(a) says 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. Section 16004(c) adds a presumption: a transaction between the trustee and a beneficiary, during the trust or while the trustee's influence remains, by which the trustee obtains an advantage from the beneficiary is presumed to violate the trustee's fiduciary duties. A presumption affecting the burden of proof means the trustee, not the beneficiary, must then prove the transaction was proper. The presumption does not apply to an agreement between trustee and beneficiary about hiring or paying the trustee.
Compensation is its own frequent flashpoint. If the trust instrument does not specify the trustee's pay, the trustee is entitled to reasonable compensation under the circumstances (Probate Code section 15681). A trustee may not charge an increased fee without first giving at least 60 days' written notice to the beneficiaries section 15686(b) lists: 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 a fee increase and given an address. Under section 15686(c), if a beneficiary files a section 17200 petition to review the increase or remove the trustee and serves it before that 60-day period ends, the increase does not take effect until the court orders otherwise or the petition is dismissed.
When Co-Trustees Disagree: Deadlock and Its Consequences
Co-trustees, unlike a successor who takes over alone, have to work alongside each other. When they are siblings who disagree about whether to sell the family house, or who no longer speak, the trust can stop moving entirely. That paralysis is often what brings a co-trustee to look for answers in the first place.
Whether co-trustees in a particular trust must act together on every decision depends on the trust instrument and on law not covered here, and this page does not state a general rule about it. What the Probate Code does address is the consequence of a breakdown. Hostility or lack of cooperation among cotrustees that impairs the administration of the trust is one of the grounds for removal listed in Probate Code section 15642(b), a list that includes other grounds as well. The key word is "impairs": ordinary disagreement is not enough on its own.
Either a beneficiary or a co-trustee may bring a section 17200 petition asking the court to resolve the internal affairs of the trust, including by instructing the trustees or deciding a question of power or duty. If a breach is committed or threatened, Probate Code section 16420(a) allows a beneficiary or co-trustee to ask for a receiver or temporary trustee to take possession of the trust property and administer the trust. And under Probate Code section 17206, the court on a petition may make any orders necessary or proper to dispose of the matters presented, including appointing a temporary trustee to administer the trust in whole or in part. The mechanics are covered in more detail on the Probate Code 17200 petition page.
Removing a Successor Trustee in California
Removal is available through more than one route. Under Probate Code section 15642(a), 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 grounds for court removal listed in section 15642(b) include:
- the trustee has committed a breach of the trust;
- the trustee is insolvent or otherwise unfit to administer the trust;
- hostility or lack of cooperation among cotrustees impairs administration;
- the trustee fails or declines to act; and
- the trustee's compensation is excessive under the circumstances.
The statute says the grounds "include" these, so the list is partial. Removal is not automatic on any of them; the court weighs the evidence. While a removal petition is pending, section 17206 allows the court to appoint a temporary trustee where that is necessary or proper.
Removal is one remedy among several. If a trustee commits or threatens to commit a breach of trust, Probate Code section 16420(a) lets a beneficiary or co-trustee bring a proceeding for whichever of these purposes is appropriate: to compel the trustee to perform the trustee's duties; to enjoin the trustee from committing a breach; to compel the trustee to redress a breach by payment of money or otherwise; to appoint a receiver or temporary trustee; to remove the trustee; subject to section 18100, to set aside acts of the trustee; to reduce or deny the trustee's compensation; subject to section 18100, to impose an equitable lien or a constructive trust on trust property (a court order treating property as held for the trust's benefit); and, subject to section 18100, to trace trust property that was wrongfully disposed of and recover it or its proceeds. Section 16420(b) says these remedies do not prevent resort to any other appropriate remedy under statute or common law.
Money liability is called surcharge. Under Probate Code section 16440(a), a trustee who commits a breach of trust is chargeable with whichever of these is appropriate: 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. Surcharge is not automatic. Under section 16440(b), if the trustee acted reasonably and in good faith under the circumstances as known to the trustee, the court may in its discretion excuse the trustee in whole or in part if that would be equitable. A trustee who made a poor but honest decision is in a different position from one who helped himself.
How Beneficiaries Can Compel Information and Accountings
For a beneficiary who has asked, and asked again, and received nothing, the petition process gives the request a court behind it. Section 17200(b)(7) sets thresholds that matter:
- Information. A petition to compel the trustee to provide information under section 16061 is available if the trustee has failed to provide the requested information within 60 days after the beneficiary's reasonable written request, and the beneficiary has not received it within the six months preceding the request.
- Account. A petition to compel an account 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 the six months preceding the request.
The request being in writing matters, as does its date. Section 17200(b)(7) also lets a beneficiary seek to compel the trustee to provide a copy of the terms of the trust. Once a petition is before it, the court may make any orders necessary or proper under section 17206, which can include a temporary trustee if the circumstances call for one.
Accounts also start clocks. Under Probate Code section 16460(a), a claim for breach of trust is barred unless a proceeding is commenced within three years after the beneficiary receives an interim or final account or other written report that adequately discloses the existence of the claim; or, where no account or report adequately discloses the claim or none is received, within three years after the beneficiary discovered, or reasonably should have discovered, the subject of the claim. An account "adequately discloses" a claim if it gives enough information that the beneficiary knows of the claim or reasonably should have inquired into it. A beneficiary who sets aside a thick account unread may still be charged with what it disclosed.
The Trustee Notification Requirement and Contest Deadlines
Probate Code section 16061.7(a) requires the trustee to serve a notification in the events it lists, including when a revocable trust or part of one becomes irrevocable because of a settlor's death, and whenever there is a change of trustee of an irrevocable trust. That second event matters on a page about successor trustees: when one trustee replaces another on an irrevocable trust, the new trustee's notification obligation is triggered.
The notification sets the deadline for contesting the trust, meaning a challenge to the trust's validity itself, such as a claim that a late-life amendment was the product of undue influence or lack of capacity. Under Probate Code section 16061.8, a person served with the notification after a settlor's death under section 16061.7(a)(1) cannot bring an action to contest the trust more than 120 days from the date the notification is served on that person, or 60 days from the date a copy of the terms of the trust is delivered to that person during that 120-day period, whichever is later.
Two triggers, then. The 120 days runs from service of the notification. The 60 days runs from delivery of the trust terms, but only if that delivery happens inside the 120-day window. Neither period runs from the date of death or from the date the trust became irrevocable. And the section 16061.8 deadline governs contests by people served with that notification; it is not a rule that every trust contest everywhere must be filed in 120 days. A dispute over how a trustee is managing a valid trust is a different claim with its own limitations rule, described above. The how to contest a trust page covers the contest itself.
A no contest clause, which threatens to cut off a beneficiary who challenges the trust, does not reach every challenge. Under Probate Code section 21311(a), it may be enforced only against a direct contest brought without probable cause and, only if the clause expressly says so, a pleading challenging a transfer on the ground the property was not the transferor's, or a creditor's claim. Probable cause exists if, at the time of filing, the facts known to the contestant would cause a reasonable person to believe there is a reasonable likelihood the requested relief will be granted after an opportunity for further investigation or discovery (section 21311(b)).
Presumptions That Affect Successor Trustee Disputes: Undue Influence and Donative Transfers
These disputes often turn on who the successor trustee is and what they received. When the person now running the trust is also the person who helped write the last amendment, or who was caring for the settlor at the end, California law can shift the burden of proof.
Under Probate Code section 21380(a), a provision of an instrument making a donative transfer, meaning a gift, to certain persons is presumed to be the product of fraud or undue influence. Those persons include the person who drafted the instrument; a person who transcribed it or caused it to be transcribed and was in a fiduciary relationship with the transferor at the time; and a care custodian of a transferor who is a dependent adult, but only if the instrument was executed while the care custodian was providing services or within 90 days before or after that period. The statute describes other persons as well.
The presumption affects the burden of proof: the beneficiary of the gift must rebut it by clear and convincing evidence. For a transfer to the drafter, and to the people the statute associates with the drafter, the presumption is conclusive and cannot be rebutted. A beneficiary who fails to rebut it bears all costs of the proceeding, including reasonable attorney's fees. None of this means every gift to a caregiver, relative or helper is presumed invalid; the presumption applies only to the persons and circumstances the statute describes.
Recovery of property has its own statute. Under Probate Code section 859, if a court finds that a person has in bad faith wrongfully taken, concealed or disposed of property belonging to a trust or a decedent's estate, or has taken, concealed or disposed of it by undue influence in bad faith or through elder or dependent adult financial abuse, that person is liable for twice the value of the property recovered by an action under that part. The court may also, in its discretion, award reasonable attorney's fees and costs against that person. Neither the doubled amount nor fees follows from a dispute alone; each depends on the court's finding.
What This Site Covers
This site covers disputes: beneficiary claims, successor trustee conduct and removal, breach of fiduciary duty, contested accountings, undue influence and related trust litigation in California. It does not cover drafting a trust, estate planning, or trust administration where no one disputes anything, and matters outside California are outside its scope. Not every disagreement with a trustee is a breach of trust, either; a slow distribution or an unpopular sale can be entirely lawful.
Discussing a Successor Trustee Dispute
Successor trustee disputes are rarely about one bad act; they are about a pattern that shows up in dates, documents and silence. A consultation about this kind of dispute typically looks at the trust and every amendment, the trustee's notification and when it was served, written requests for information and the replies, any accounts, and the transactions that raised concern, such as property sales, payments to the trustee or changes made near the settlor's death. For readers whose question is about setting up a trust or administering one no one is contesting, this page is not the right starting point.

Frequently asked questions
What is a successor trustee?
A successor trustee is the person or institution named in a trust instrument to take over the trust when the original trustee dies, resigns or becomes incapacitated. A co-trustee, by contrast, serves at the same time as another trustee rather than afterward.
What happens when co-trustees disagree?
Ordinary disagreement can usually continue without court involvement, but hostility or lack of cooperation that impairs the trust's administration is one of the grounds for removal in Probate Code section 15642(b). A beneficiary or co-trustee may petition under section 17200, and the court may appoint a temporary trustee under section 17206.
Can a successor trustee be removed in California?
Yes. Under Probate Code section 15642(a), removal may happen under the trust instrument, by the court on its own motion, or on a section 17200 petition of a settlor, co-trustee or beneficiary. Grounds include breach of trust, unfitness, failing or declining to act and excessive compensation; the court decides on the evidence.
What type of trust cannot be changed?
An irrevocable trust is one the settlor can no longer revoke. In disputes, the key moment is often when a revocable trust becomes irrevocable because a settlor dies, which triggers the trustee's notification under Probate Code section 16061.7.
What can a beneficiary do if a successor trustee refuses to provide information?
The beneficiary can make a reasonable written request under Probate Code section 16061. If the trustee fails to provide the information within 60 days and the beneficiary has not received it within the six months before the request, a petition to compel is available under section 17200(b)(7).
How long does a beneficiary have to contest a trust in California?
For a person served with the trustee's notification after a settlor's death, Probate Code section 16061.8 bars a contest brought more than 120 days after the notification is served, or 60 days after a copy of the trust terms is delivered during that 120-day period, whichever is later.
What remedies are available if a successor trustee breaches their duties?
Probate Code section 16420(a) allows proceedings to compel performance, enjoin a breach, compel payment or other redress, appoint a receiver or temporary trustee, remove the trustee, reduce or deny compensation and, subject to section 18100, set aside acts, impose a lien or constructive trust, and trace property. Other remedies remain available; none is automatic.
How long does a beneficiary have to bring a breach of trust claim?
Under Probate Code section 16460(a), three years after receiving an account or written report that adequately discloses the claim; or, if none discloses it or none is received, three years after the beneficiary discovered or reasonably should have discovered the subject of the claim.
