California Trust Contest Attorney: What the Law Allows and How to Move Forward
Last updated October 9, 2026
The issue in brief
Served a trustee's notice? A California trust contest can't be brought more than 120 days after service, or 60 days after receiving the trust terms, if later.
If you believe a California trust or a late amendment does not reflect what the person who made it truly wanted, a trust contest asks the Superior Court to set it aside on grounds such as undue influence, lack of capacity or fraud. A trust contest attorney examines the documents, the deadline and the evidence before anything is filed.
Most people facing a possible trust contest arrive here after something specific: a parent's trust was rewritten in the last year or two of life, a sibling or a new caregiver suddenly became the main beneficiary, or an envelope arrived from a trustee with a formal notice and a short deadline printed on it. You may be grieving and angry at the same time, unsure whether what happened was wrong or merely unfair, and worried that challenging the document will cost you whatever share you still have. Some readers are on the other side, a trustee or family member who has just been told the trust will be attacked. This page lays out what California law actually says about those disputes, for either side.
It covers what a trust contest is, the deadline that governs it, the recognized grounds, how no-contest clauses work, what beneficiaries can demand of a trustee, and how trustee removal and surcharge fit alongside a contest.
What a Trust Contest Is Under California Law
A trust contest is a court proceeding that challenges the validity of the trust instrument itself, or of one of its amendments. It argues that the document, or part of it, should not be given effect. That differs from a petition about how a trustee is managing the trust, and from a request that the trustee produce an accounting, a formal report of what came in, what went out and what remains.
The forum is the Superior Court of California for the relevant county, sitting in its probate role. Under Probate Code section 17200(a), a trustee or beneficiary may generally petition the court concerning the internal affairs of a trust or to determine whether a trust exists, and section 17200(b) lists proceedings that include, but are not limited to, determining the validity of a trust provision, construing the instrument and settling the trustee's accounts. More detail on that petition is on this site's page on the Probate Code 17200 petition.
The grounds usually raised are lack of capacity, undue influence, fraud, duress, mistake and failure to sign the document with the formalities California requires. "Undue influence" is a defined legal term: Probate Code section 86 gives it the meaning set out in the Welfare and Institutions Code, and states that it supplements, rather than replaces, the common law meaning.
A contest and a breach-of-trust claim often grow out of the same facts. A contest attacks the document. A breach-of-trust petition under Probate Code section 16420 attacks the trustee's conduct. A caregiver who obtained an amendment and then sold the house to themselves may face both.
The 120-Day Deadline and When It Applies
The clock that matters most in a California trust contest starts when the trustee serves a notice, not when the person dies. Under Probate Code section 16061.8, a person served with the trustee's notification 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, or 60 days from the date a copy of the terms of the trust is delivered to that person during the 120-day period, whichever is later. The rule applies whether the notice was served on time or late.
In plain terms: if you were served on a given day and never asked for the trust, the 120-day period governs. If you requested and received a copy of the trust terms during those 120 days, you have until 60 days after delivery or the end of the 120 days, whichever comes last.
The notification duty itself comes from Probate Code section 16061.7(a). The events that require it include when a revocable trust, or a portion of one, becomes irrevocable because a settlor (the person who created the trust) has died, and whenever the trustee of an irrevocable trust changes. The list is partial; the section names other triggering events as well.
Because service starts this particular clock, a person who was never served is not bound by the section 16061.8 deadline running from that trigger. That does not mean no time limit applies at all; other rules may, and an attorney can say which deadline governs a particular set of facts. If a notice has arrived, the date of service and the date any copy of the trust was delivered are the two dates worth writing down.
Grounds for Contesting a Trust in California
Each ground for a contest turns on evidence about a specific moment and a specific relationship. The question is never simply whether the result seems unfair.
Lack of capacity. Capacity is judged at the time the document was signed. A diagnosis such as dementia does not, by itself, establish that a person lacked capacity; many people with a diagnosis have lucid periods, and many contests are won or lost on what the person understood on the signing day. For wills, Probate Code section 6100.5 sets out the test: whether the person could understand the nature of the act, understand and recollect the nature and situation of their property, and remember and understand their relations to living descendants, spouse and parents and those whose interests the will affects, or whether delusions or hallucinations caused a disposition the person otherwise would not have made.
Undue influence. Section 86 supplies the statutory meaning by reference to the Welfare and Institutions Code. These claims usually rest on who controlled access to the person, who arranged the lawyer and the signing, and how far the new document departed from earlier ones.
Fraud and duress. Fraud is a document procured through misrepresentation; duress is one procured through coercion.
Execution formalities. A trust or amendment that was not signed in the way California law or the trust's own amendment clause requires may be challenged on that basis alone.
The section 21380 presumption. Probate Code section 21380(a) presumes that a provision making a donative transfer, meaning a gift, is the product of fraud or undue influence when it benefits certain people, including the person who drafted the instrument; a person who transcribed it, or caused it to be transcribed, while in a fiduciary relationship with the transferor; and a care custodian of 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 section also covers a care custodian who began a marriage, cohabitation or domestic partnership with the dependent adult within the time limits the statute sets.
The presumption shifts the burden of proof, and it can generally be rebutted by clear and convincing evidence. It is conclusive, meaning it cannot be rebutted, for a transfer to the drafter and to the people section 21380(c) associates with the drafter. A beneficiary who fails to rebut it bears all costs of the proceeding, including reasonable attorney's fees. The presumption does not reach every gift to a relative, friend or helper; it applies only to the categories the statute describes. This site's page on how to contest a trust covers the filing itself.
No-Contest Clauses: What They Can and Cannot Do
Many readers reasonably wonder whether challenging the trust will forfeit their share. A no-contest clause is a provision that penalizes a beneficiary who challenges the document, usually by cutting off that person's gift. Under Probate Code section 21311(a), it may be enforced only against three types of contests: a direct contest brought without probable cause; a pleading challenging a transfer on the ground that the property was not the transferor's at the time, but only if the clause expressly says so; and the filing of a creditor's claim or an action based on it, again only if the clause expressly says so.
Probable cause, under section 21311(b), 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. A direct contest filed with probable cause is not subject to enforcement of the clause.
So a no-contest clause does not automatically disinherit anyone who challenges a trust. It does mean the facts known at the moment of filing carry real weight, and whether they amount to probable cause is one of the central questions an attorney evaluates before a contest is filed.
Trustee Duties and What Beneficiaries Can Demand
Not every dispute over a trust is a contest. Often the document is not in question at all; the problem is a trustee who will not explain what is happening. If you have been asking for months and getting silence, these are the rules that apply.
Probate Code section 16060 requires the trustee to keep the beneficiaries reasonably informed of the trust and its administration. Under section 16061, generally, on a beneficiary's reasonable request, the trustee must provide requested information about the administration relevant to that beneficiary's interest, subject to the exceptions in section 16069.
The duty to account is narrower. Section 16062 requires the trustee, with stated exceptions, to account at least annually, at the termination of the trust and upon a change of trustee, 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. Even where the trust instrument or a beneficiary's own writing waives the account, section 16064 allows the court to compel an account upon a showing that it is reasonably likely a material breach of the trust has occurred.
When requests go unanswered, section 17200(b)(7) allows a petition to compel information if the trustee has not provided it within 60 days after a reasonable written request and the beneficiary has not received it within the six months before the request. It allows a petition to compel an account if the trustee has not submitted a requested account within 60 days after a written request and no account has been made within the preceding six months.
Behind those reporting duties sits the duty of loyalty. Section 16004(a) bars the trustee from using or dealing with trust property for the trustee's own profit or for any purpose unconnected with the trust, and from taking part in any transaction in which the trustee has an interest adverse to the beneficiary. Under section 16004(c), a transaction between trustee and beneficiary by which the trustee obtains an advantage is presumed to violate the trustee's fiduciary duties. That presumption affects the burden of proof and does not apply to an agreement about the trustee's hiring or compensation.
When a trustee commits or threatens a breach of trust, section 16420(a) lets a beneficiary or cotrustee bring a proceeding for any appropriate purpose: to compel performance of the trustee's duties; to enjoin the breach; to compel redress by payment of money or otherwise; to appoint a receiver or temporary trustee; to remove the trustee; to set aside the trustee's acts; to reduce or deny compensation; to impose an equitable lien or constructive trust on trust property; and to trace and recover wrongfully disposed property or its proceeds. The set-aside, lien or constructive trust, and tracing remedies are each subject to section 18100. Section 16420(b) preserves any other appropriate statutory or common law remedy.
Probate Code section 859 adds a separate remedy. If a court finds that a person in bad faith wrongfully took, concealed or disposed of property belonging to a trust or a decedent's estate, or took 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, and the court may, in its discretion, also award reasonable attorney's fees and costs against that person. Neither is automatic; each depends on the court's finding. The broader set of remedies is summarized on this site's California trust litigation attorney page.
Trustee Removal and the Breach-of-Trust Statute of Limitations
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 section 15642(b) lists include a breach of trust; insolvency or other unfitness to administer the trust; hostility or lack of cooperation among cotrustees that impairs administration; failing or declining to act; and compensation that is excessive under the circumstances. The list is not exhaustive.
While a petition is pending, section 17206 gives the court discretion to 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.
A trustee found to have committed a breach may be surcharged, meaning ordered to pay the trust. Under section 16440(a), the trustee is chargeable with whichever is appropriate: any loss or depreciation in value 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 had the breach not occurred. Under section 16440(b), the court may excuse a trustee who acted reasonably and in good faith under the circumstances as known to the trustee, in whole or in part, if that would be equitable. A surcharge is not automatic.
Timing matters here too. Under section 16460(a), a breach-of-trust claim 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. Where no such account or report discloses it, or none is received, the three years run from when 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. For a trustee accused of misconduct, the same provisions define both the exposure and the defenses.
What This Site Covers
This site is about disputes only: trust and will contests, breach-of-trust claims, trustee removal, compelled accountings and related fiduciary litigation in California. It does not cover estate planning, drafting or amending a trust, or administering a trust or estate when nobody disagrees about anything, and it does not address matters outside California. Not every disagreement with a trustee is a breach, and not every disappointing trust is invalid; the law described above is what separates the two.
Discussing a Trust Contest With an Attorney
A trust contest turns on a small number of facts that are easy to lose track of in a family crisis: the date the trustee's notice was served, the date the trust terms arrived, who drafted the last amendment and who was in the room, what the earlier versions said, and what the medical and financial records show about the signing period. A consultation about a dispute like this typically looks at those documents and dates, any no-contest clause, and the trustee's conduct since the death. For readers whose question is how to set up or update their own trust rather than how to challenge an existing one, this page is not the place to start. When you are ready to describe what happened, you can request a consultation about your dispute through California Trust Litigation Lawyers.

Frequently asked questions
How do you contest a trust in California?
A trust contest is brought as a petition in the Superior Court of California for the relevant county, under the court's authority over a trust's internal affairs and the validity of its provisions in Probate Code section 17200. The petition rests on grounds such as lack of capacity, undue influence or fraud, and if a trustee's notification has been served, it must be filed within the period section 16061.8 sets.
What is the deadline to contest a trust in California?
For a person served with the trustee's notification under Probate Code section 16061.7(a)(1), the deadline is 120 days from service, or 60 days from delivery of a copy of the trust terms during that 120-day period, whichever is later. The clock is triggered by service of the notice, not by the date of death or the date the trust became irrevocable, and a person never served is not subject to this particular trigger.
What are the grounds for contesting a trust in California?
The usual grounds are lack of capacity at the time of signing, undue influence as defined by reference in Probate Code section 86, fraud, duress, mistake and failure of execution formalities. A diagnosis alone does not establish incapacity. Gifts to certain people, such as the drafter or a care custodian of a dependent adult within the statute's time limits, are presumed to result from fraud or undue influence under section 21380.
Can a no-contest clause stop me from challenging a trust?
Not if the contest is a direct contest filed with probable cause. Under Probate Code section 21311, the clause can be enforced only against a direct contest brought without probable cause and, where the clause expressly says so, certain property-ownership challenges and creditor's claims. Probable cause depends on the facts known at the time of filing.
What can a beneficiary do if a trustee refuses to provide information?
A beneficiary may petition the court to compel the information under Probate Code section 17200(b)(7) if the trustee has not provided it within 60 days after a reasonable written request and the beneficiary has not received it within the preceding six months. The underlying duty to keep beneficiaries reasonably informed is in section 16060. What the court orders depends on the facts.
Can a trustee be removed in California?
Yes. 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 in section 15642(b) include breach of trust, insolvency or unfitness, and excessive compensation, among others.
Is there a time limit to sue a trustee for breach of trust?
Generally, three years. Under Probate Code section 16460(a), the period runs from receipt of an account or written report that adequately discloses the claim; where no such account or report discloses it, or none is received, it runs from when the beneficiary discovered or reasonably should have discovered the subject of the claim.
