The Deadline to Contest a Trust in California

If you believe a trust was the product of pressure, fraud, or a loved one's failing capacity, the most important thing to understand is this: your time to act may be measured in days, not years. California law lets trustees start a clock that can bar a trust contest just 120 days after a statutory notice is mailed. People lose meritorious cases simply by waiting. Here is how the deadline works.

The notice that starts the clock

When a revocable trust becomes irrevocable, typically at the settlor's death, the trustee must serve a notification under Probate Code section 16061.7 on beneficiaries and heirs. It identifies the trust, the trustee, and your right to request a copy of the trust terms, and it contains a warning that you may not bring an action to contest the trust more than 120 days from the date the notification is served (or 60 days from delivery of the trust terms, whichever is later).

That paragraph is not boilerplate. Once the notice is properly served, the contest window is genuinely short, and courts enforce it.

What counts as a "contest"

The deadline applies to actions challenging the validity of the trust itself: claims of lack of capacity, undue influence, fraud, forgery, or improper execution. Our article on undue influence in California wills and trusts describes the most common theory. Other kinds of claims, such as a petition to remove a bad trustee or compel an accounting, run on different timelines. Sorting out which deadline applies to which claim is exactly what early legal review is for.

Why the window is so short

The legislature wanted trusts to be administered with finality: assets distributed, taxes paid, families moving on. The price of that efficiency falls on anyone with doubts about the trust, which is why acting quickly after a death is not paranoia. It is diligence.

What to do if you just received a notice

1. Calendar the date. Note when the notice was mailed and count forward 120 days. Treat it as a hard deadline.
2. Request the trust and amendments in writing. You are entitled to the terms. Compare the final version against earlier estate plans if you can. See whether a trustee must provide the full trust.
3. Preserve evidence. Medical records, caregiver arrangements, bank activity, and correspondence around the time of any amendment are the raw material of a contest.
4. Get a legal evaluation now. An attorney can assess grounds, file a protective contest before the bar date if warranted, and evaluate related claims such as trustee removal.

What if the deadline already passed?

Do not assume the door is closed. The bar depends on proper service of a compliant notice, and defects in the notice or its service can change the analysis. Separate claims against a trustee for their own misconduct may remain available. An attorney can tell you what is still on the table.
