You just received a formal letter from a trustee. It uses words like irrevocable and warns you that you have a limited window to act. Maybe the trust leaves you far less than you expected. Maybe it was changed right before your parent passed away, under circumstances that felt anything but right. Here is the hard truth: in California, you may have only 120 days to do something about it. Miss that window, and the door to challenging the trust can close permanently, no matter how strong your case might be.
This article breaks down what the 120-day rule means, where it comes from in California law, when the clock starts ticking, and what your options are if you believe a trust was the product of fraud, undue influence, or a lack of mental capacity.
Where Does the 120-Day Rule Come From?
The 120-day rule traces back to two sections of the California Probate Code. Probate Code Section 16061.7 requires a trustee to formally notify beneficiaries and heirs when a revocable trust becomes irrevocable, which most often happens upon the death of the person who created it, known as the settlor or trustor. The trustee must serve this notice within 60 days of that triggering event.
Once you receive that notice, Probate Code Section 16061.8 sets the clock running. That statute gives you 120 days to file a trust contest. The law requires that a warning appear in bold type in every trustee notice. It reads, in relevant part:
“You may not bring an action to contest the trust more than 120 days from the date this notification by the trustee is served upon you or 60 days from the date on which a copy of the terms of the trust is delivered to you during that 120-day period, whichever is later.”
When Does the Clock Start Running?
The 120-day period begins the moment the trustee serves the notification on you. For mailed notice, the clock starts on the date the notice is deposited in the mail, not the date you actually receive it. For personal delivery, it begins on the date of delivery. There is no grace period added for postal transit time.
The California Court of Appeal confirmed this in Bridgeman v. Allen (2013) 219 Cal.App.4th 288, holding that mailing is complete upon deposit and that the 120-day period is not extended simply because the notice went through the postal system.
There is one important nuance. If the trustee serves the notice but does not attach a full copy of the trust at that time, and you later receive a copy during the 120-day window, you get 60 additional days from the date you receive that copy, whichever deadline falls later. This extension only applies if you actually receive the trust terms within the original 120-day period.
What happens if the trustee never sends the notice at all? When proper Section 16061.7 notice is never served, the applicable deadline becomes far less certain. Depending on the legal theories involved, courts may look to different statutes of limitations, including the fraud provision under Code of Civil Procedure Section 338(d), and outcomes have varied. There is no single California rule that guarantees a fixed alternative window in that situation. If you never received a trustee notice, consult a trust litigation attorney right away to assess what deadlines apply to your specific facts.
Who Can Contest a Trust in California?
Not everyone has legal standing to file a trust contest. To challenge a trust under California law, you generally must have a financial stake in the outcome. That typically means you are one of the following:
- A current beneficiary named in the trust
- A beneficiary named in a prior version who was removed or had their share reduced
- An heir-at-law, meaning someone who would inherit under California’s intestate succession laws if the trust did not exist
- In some cases, a disinherited spouse or omitted child with rights under California community property or probate law
Standing matters before a single document is filed. An attorney can confirm whether you have the right to bring a contest before any deadlines pass.
What Are the Valid Grounds for Contesting a Trust?
Disagreeing with how a trust divides assets is not enough on its own. California courts require actual legal grounds. The most common are:
Lack of Mental Capacity
The settlor must have had the mental capacity to sign the trust at the time it was created or changed. California courts look at specific mental functions under Probate Code Sections 6100.5 and 811, including alertness, information processing, and decision-making. Occasional confusion or mild memory lapses are generally not enough to prove incapacity on their own.
Undue Influence
Undue influence means excessive persuasion that overcomes a person’s free will, as defined under Welfare and Institutions Code Section 15610.70. Courts weigh the settlor’s vulnerability, the influencer’s authority, and whether the result was fair. Under Probate Code Section 21380, a presumption of undue influence arises when the person who benefited also drafted the trust or served as a care custodian.
Fraud, Forgery, or Misrepresentation
A trust may be challenged if the settlor was deceived into signing it, misled about its contents, or if the signature itself was forged. The label you put on the lawsuit does not change the deadline that applies. In Hamilton v. Green (2023) 98 Cal.App.5th 417, the California Court of Appeal held that any claim whose practical effect is to invalidate or set aside a trust or an amendment falls within the 120-day limitation period of Probate Code Section 16061.8, regardless of how it is styled in the pleadings.
Duress or Mistake
If the settlor was threatened or intimidated into creating or amending a trust, or if the document was executed based on a material mistake of fact or law, these may also serve as grounds for a valid contest under California law.
What About No-Contest Clauses?
Many California trusts contain a no-contest clause, sometimes called an in terrorem clause. These provisions threaten to disinherit any beneficiary who challenges the trust. California does enforce them in certain situations, but the law also builds in meaningful protection.
Under Probate Code Section 21311, a no-contest clause is only enforceable against a direct contest filed without probable cause. If you have a solid, reasonable factual basis for your challenge, the clause generally will not cost you your inheritance even if you lose. Probable cause in this context means that a reasonable person, armed with the same facts you had at the time of filing, would believe there was a realistic chance the contest could succeed.
The risk of getting this wrong is severe. In Meiri v. Shamtoubi (2022) 81 Cal.App.5th 606, the California Court of Appeal held that a contestant who filed after the 120-day deadline had already passed had no probable cause at the time of filing because a procedural bar already existed. As a result, the no-contest clause was enforced, and she lost her right to any inheritance under the trust, effectively treated as though she had predeceased the trustors. An untimely filing combined with a no-contest clause can be one of the most damaging outcomes in trust litigation.
What Steps Do You Take to File a Trust Contest in California?
If you believe you have grounds to challenge a trust, here is how the process generally works:
- Request a copy of the trust. Upon receiving the trustee’s notice under Section 16061.7, you have the right to request a full copy of the trust document. Review it carefully against what you were told or expected.
- Consult a trust litigation attorney immediately. Do not wait until the deadline approaches. Building a trust contest case involves gathering medical records, financial documents, witness statements, and sometimes forensic document analysis. That takes time.
- File a petition in the appropriate California Superior Court. The contest is filed in the probate division of the county where the trustee administers the trust. Depending on your situation, that may be San Diego, Orange, Los Angeles, Riverside, or San Bernardino County.
- Engage in discovery. Once the case is filed, both sides exchange evidence through depositions, document requests, and subpoenas. This phase often reveals the clearest picture of what actually happened.
- Mediation or trial. Many California trust contests resolve through mediation. If the parties cannot reach an agreement, the matter proceeds to a probate judge who reviews the evidence and issues a ruling.
Key Takeaways
- The 120-day deadline is set by California Probate Code Sections 16061.7 and 16061.8. Courts generally treat it as a firm cutoff with very limited exceptions.
- For mailed notices, the clock starts on the date the notice is deposited in the mail, not the date you receive it. For personal delivery, it starts on the date of delivery.
- If you receive a copy of the trust during the 120-day window and it was not included with the original notice, you may get 60 additional days from the date you receive it, whichever deadline is later.
- Valid grounds include lack of mental capacity, undue influence, fraud, forgery, duress, and mistake. The capacity analysis involves multiple factors under Probate Code Sections 6100.5 and 811.
- The Probate Code Section 21380 presumption of undue influence applies only to a narrow statutory category, primarily drafters and care custodians of dependent adults, not to all relationships.
- Filing an untimely contest in a trust with a no-contest clause can result in the loss of your entire inheritance. Do not wait.
Frequently Asked Questions
Can I contest a trust after the 120 days have passed?
In most cases, once the 120-day window closes, the right to challenge the trust’s validity is gone. Courts in California treat this deadline seriously. If the trustee never properly served the required notice under Section 16061.7, a different and less predictable deadline may apply depending on the claims raised, but you should never rely on that possibility. The moment you have any concern about a trust, seek legal advice.
Does the 120-day rule apply to trust amendments, not just the original trust?
Yes. Under the holding in Hamilton v. Green (2023) 98 Cal.App.5th 417, any claim whose practical effect is to invalidate a trust or an amendment falls within the 120-day limitation period, regardless of how the lawsuit is labeled.
What if I never received the trustee’s notification?
If you never received a proper Section 16061.7 notice, the 120-day clock may not have been triggered against you. Trustees are required to serve all beneficiaries and heirs, and a failure to do so may constitute a breach of fiduciary duty. The alternative deadline that applies in that situation depends on the specific claims and facts involved. Speak with an attorney as soon as possible.
Can I still receive anything from the trust even if I lose a contest?
Potentially yes, if the trust did not include a valid no-contest clause, or if the clause is unenforceable because you had probable cause to file. If the trust does contain a no-contest clause and a court finds you lacked probable cause, you could lose your inheritance entirely. This is why a careful legal evaluation before filing anything is so important.
