The statute of limitations on trusts in California is not a single deadline but a set of them, each tied to a different kind of claim. The two most common: 120 days to challenge whether a trust was validly created, and three years to sue a trustee for mismanaging the trust or breaching fiduciary duties. A separate one-year cutoff applies to claims against a deceased settlor. Miss the applicable deadline and the claim is gone, regardless of how strong it would have been.
120 Days to Contest a Trust’s Validity
When a revocable trust becomes irrevocable, usually because the settlor has died, the trustee must send a formal notification to beneficiaries and heirs under California Probate Code 16061.7. That notice includes the trust terms (or how to get them) and a boldface warning about the contest deadline.1California Legislative Information. California Probate Code 16061.7 Under Probate Code 16061.8, you have 120 days from receiving that notification to file a court action contesting the trust, or 60 days from receiving a copy of the trust document during that 120-day window, whichever is later.2California Legislative Information. California Probate Code 16061.8
The “whichever is later” language matters when the trust document arrives well after the initial notice. If the trustee sends notification on day one but delivers the trust on day 100, you get 60 days from day 100. Most trustees send both together, so the 120 days usually controls.
The 120-day window applies to every theory of invalidity. Lack of capacity, undue influence by a caregiver, improper execution: same deadline. Once it passes, the right to challenge the trust’s creation is gone.
If the Trustee Never Sends Notice
No notification, no clock. A potential contestant may have significantly more time. But “more time” isn’t unlimited time. Courts can still dismiss a stale claim under the doctrine of laches if the challenger waited unreasonably long and the delay caused real harm to the other side. A trustee who has already distributed assets, sold property, or made other irreversible decisions during the wait has a strong laches argument. Even without formal notice, do not sit on a potential claim.
Three Years to Sue a Trustee for Misconduct
Contesting the trust and challenging how the trustee runs it are two different claims with two different deadlines. Under Probate Code 16460, a beneficiary has three years from the date they discovered, or reasonably should have discovered, the trustee’s misconduct.3California Legislative Information. California Probate Code 16460 This covers self-dealing, mismanaged investments, failure to distribute, and other breaches of fiduciary duty.
The clock is tied to discovery, not to when the misconduct occurred. A trustee who quietly siphoned funds for five years doesn’t get a free pass because the conduct started long ago. But “should have known” does real work. Courts look at whether you ignored obvious warning signs, skipped accountings, or failed to ask basic questions.
How an Accounting Shortens the Deadline
If a trustee provides a formal accounting that adequately discloses the conduct in question, the three-year clock starts running from the date you receive that accounting, whether or not you actually read it carefully.3California Legislative Information. California Probate Code 16460 Trustees are required to account at least annually, when the trust terminates, and when a trustee changes, under Probate Code 16062.4California Legislative Information. California Probate Code 16062 Letting accountings pile up unread can silently destroy your right to challenge the transactions inside them.
Suing Over Pre-Death Conduct
Can beneficiaries sue a trustee for misconduct that occurred while the settlor was still alive? The California Supreme Court said yes in Estate of Giraldin (2012), holding that after the settlor dies, beneficiaries have standing to assert claims for breaches of duty the trustee owed the settlor, to the extent that misconduct reduced the trust’s value.5Stanford Law School – Robert Crown Law Library. Estate of Giraldin – 55 Cal.4th 1058 The court did not decide whether the claims there were time-barred, so the ordinary limitations rules still apply. The standing question, however, is settled.
One Year to Sue the Settlor After Death
California Code of Civil Procedure 366.2 imposes a hard one-year cutoff on claims based on a deceased person’s liability. If someone dies before the applicable statute of limitations on a claim against them has run, you have one year from the date of death to file, regardless of how much time was left on the underlying statute.6California Legislative Information. California Code of Civil Procedure 366.2
This matters most for creditors and anyone with a contract or tort claim against the settlor personally. The statute allows tolling only for a few narrow provisions, including the creditor claims process in probate estates.6California Legislative Information. California Code of Civil Procedure 366.2
What Can Extend a Deadline
California courts recognize a handful of doctrines that push a deadline out when the trustee is the reason for the delay. None of them are a blank check to wait.
Fraud
When a trustee falsifies records, lies about the trust’s finances, or fabricates transactions, the three-year discovery clock under Probate Code 16460 does not start until the fraud is discovered or reasonably should have been.3California Legislative Information. California Probate Code 16460 The beneficiary bears the burden of showing both the fraud and that the delay in filing was reasonable.
Concealment
Concealment covers withholding critical information, refusing to hand over records, or giving evasive non-answers, without necessarily lying outright. When a trustee hides the ball, the limitations period is tolled until you discover, or reasonably should have discovered, the concealed facts. Documented requests for information and the trustee’s responses (or silence) become the evidence that the delay was justified.
Delayed Discovery
Even without active fraud or concealment, the discovery rule can extend the deadline when a beneficiary had no realistic way to know about a problem. This comes up when accountings technically exist but bury a bad transaction in vague line items, or when a loss only surfaces later through an independent audit or appraisal. Courts ask whether you exercised reasonable diligence. If you did and the problem was still hidden, the clock starts when you actually learn of it.
Equitable Tolling
Beyond the trust-specific rules, California recognizes a general equitable tolling doctrine. The California Supreme Court has described it as a narrow safety valve for “carefully considered situations,” not a routine escape hatch. To qualify, you must show timely notice to the other side of your claim and intent to pursue it, no prejudice to their ability to defend, and conduct that was both objectively reasonable and subjectively in good faith.7California Supreme Court. Saint Francis Memorial Hospital v. State Department of Public Health Ordinary neglect will not qualify.
Tolling for Minors and Incapacitated Beneficiaries
California pauses the statute of limitations for people who cannot legally protect their own interests. Under Code of Civil Procedure 352, if the person entitled to bring a claim is under 18 or lacks legal capacity when the cause of action arises, the time of that disability does not count toward the limitations period.8California Legislative Information. California Code of Civil Procedure 352 The clock starts when the disability ends: when the minor turns 18 or the incapacitated beneficiary regains capacity.
This tolling matters in trust disputes because beneficiaries are often children or elderly relatives with cognitive decline. A guardian or conservator can act sooner on their behalf, and once a representative is involved, there may be an argument that the clock should resume.
What Missing the Deadline Costs
A petition filed one day late will be dismissed without any consideration of whether the trust was forged, the trustee stole the assets, or the beneficiary was cheated out of millions. The merits become irrelevant.
The financial consequences compound. Assets that were mismanaged or stolen stay wherever the trustee put them. Distributions made under the trust’s terms stand, even if those terms were the product of undue influence you can no longer challenge. And if the trustee moves to dismiss a late-filed claim and wins, the trustee may qualify as the “prevailing party” under Code of Civil Procedure 1032, entitled to recover court costs as a matter of right.9California Legislative Information. California Code of Civil Procedure 1032 You lose the case and pay part of the other side’s litigation costs on top of your own.
