How to Contest a Trust in California
When a family member passes away and a suspicious, last-minute trust or amendment suddenly cuts you out, you do not have to accept the injustice. California law gives heirs and beneficiaries statutory rights to challenge invalid estate documents, but strict deadlines require fast, decisive action. Knowing your rights under the California Probate Code is the first step toward reclaiming what rightfully belongs to the estate.
You've read a few of these by now.
None of them were about you. That's how generic guides work. They have to cover everybody. On Caunsel you write down what's actually going on and get answers about your situation, or just talk it through out loud. If it needs follow-up, you keep it as a case, and when there's paperwork, it'll suggest what you need, write it up, and you can e-sign it right there.

In California, you cannot contest a trust simply because the distribution feels unfair or unequal. To challenge an instrument or amendment, an interested person must file a petition under California Probate Code § 17200 in the probate division of the Superior Court, establishing that the document is legally invalid.
The most common ground is undue influence, defined under California Welfare and Institutions Code § 15610.70 as excessive persuasion that overcomes the settlor's free will. Under California Probate Code § 21380, the law actually creates a rebuttable presumption of fraud or undue influence if a substantial gift was made to the person who drafted the document, a fiduciary, or a paid care custodian who isolated the decedent.
Other statutory grounds include lack of mental capacity at the time of execution, outright fraud, forgery, menace, duress, or failure to follow California execution and amendment formalities. When bad actors take advantage of an ailing elder to divert assets, the probate court has broad authority to invalidate the offending terms and restore prior instruments or intestate distribution.
The Unforgiving 120-Day Statutory Deadline
The greatest risk in California trust litigation is delay. When a revocable trust becomes irrevocable—most often upon the settlor's death—the successor trustee is required under California Probate Code § 16061.7 to serve a formal notification to all heirs and named beneficiaries within 60 days.
Under California Probate Code § 16061.8, you have only 120 days from the date that statutory notice is served (or 60 days from the date the terms of the trust are delivered to you, whichever is later) to file your contest in court. As confirmed in California appellate rulings such as Hamilton v. Green (2023), any lawsuit whose practical purpose is to set aside or invalidate a trust instrument falls strictly under this 120-day limitation.
If you let this window lapse, your claim will almost certainly be permanently barred by statute, regardless of how blatant the fraud or undue influence was. Do not wait for informal family negotiations while the trustee runs out your clock.
Confronting No-Contest Clauses and Preparing Your Case
Predatory beneficiaries and self-dealing trustees routinely rely on 'no-contest' or in terrorem clauses to intimidate disenfranchised heirs into silence. However, California Probate Code § 21311 strictly limits the enforcement of these penalty provisions.
Under California Probate Code § 21311(a)(1), a no-contest clause can only be enforced against a direct contest if the petition is brought without probable cause. Under subdivision (b), probable cause exists whenever the facts known at filing would lead a reasonable person to believe there is a reasonable likelihood that the court will grant the requested relief after an opportunity for discovery. A legitimate, well-documented challenge supported by evidence will not trigger disinheritance.
To protect your inheritance, you must organize your timeline, medical records, and communication histories immediately.

Steps
- Demand an official copy of the trust agreement, all amendments, and the proof of service for the trustee's Probate Code § 16061.7 notification.
- Calculate your exact filing deadline under California Probate Code § 16061.8 (120 days from the service date or 60 days from receiving the trust terms).
- Subpoena or request contemporaneous evidence, including the settlor's medical records, physician cognitive assessments, financial changes, and text or email correspondence with the drafting party.
- Draft and file a verified petition to determine the validity of the trust under California Probate Code § 17200 in the Superior Court of the county where the trust administration is seated, then properly serve all required parties.
Common mistakes
- Assuming the contest deadline starts when you receive the physical letter rather than the date the trustee deposited the § 16061.7 notification in the mail.
- Allowing fear of a no-contest clause to deter you when you possess valid probable cause under California Probate Code § 21311.
- Conflating a breach of fiduciary duty (how the trustee is handling funds) with a trust contest (whether the document itself is legally invalid), which require distinct statutory remedies.
- Engaging in protracted informal negotiations with an adversarial trustee while allowing your statutory 120-day window to expire.
Questions people ask
How long do I have to contest a trust in California?
Under California Probate Code § 16061.8, you generally must file your contest within 120 days of the date the trustee serves the statutory § 16061.7 notification, or within 60 days of when a copy of the trust terms is delivered to you during that period, whichever is later.
Will a no-contest clause disinherit me if I challenge the trust?
Not if you have probable cause. Under California Probate Code § 21311, a no-contest clause is only enforceable against a direct contest brought without probable cause—meaning you had no reasonable factual basis to believe the trust was invalid when you filed.
Who has legal standing to contest a trust in California probate court?
Only an 'interested person' has standing. In California, this includes statutory legal heirs who would inherit under intestate succession if the trust were invalidated, as well as beneficiaries named in the challenged instrument or any prior valid estate planning document.
Ask Caunsel to analyze whether your evidence meets California's probable cause standard under Probate Code § 21311 before your 120-day statutory contest deadline expires.
