What Is California Probate Code Section 16061.7?

California Probate Code Section 16061.7 is the statute that requires a trustee to send a formal written notice to a trust’s beneficiaries and heirs when the trust becomes irrevocable or when a new trustee takes over. The notice does two jobs at once: it tells recipients the trust exists and who is running it, and it starts a strict 120-day deadline for anyone who wants to challenge the trust in court. Miss that deadline and the right to contest is gone for good.

When the Notice Must Be Sent

Three events trigger the obligation. The most common is when a revocable trust, or any part of it, becomes irrevocable because the settlor died. The same rule applies if the trust’s own terms make it irrevocable within one year of the settlor’s death because of a condition tied to that death.¹

The second trigger is a change of trustee on a trust that is already irrevocable. Whoever steps into the role must send the notice, even if no one has died.¹

The third is less familiar. When a power of appointment that the settlor kept either takes effect or lapses at the settlor’s death, and the trust was already irrevocable (or purported to be) from the start, the notice is required. Charitable remainder trusts are exempt from this third trigger.²

The trustee has 60 days from the triggering event to serve the notice. If a person who should have received it only comes to the trustee’s attention later, a fresh 60-day clock starts from the date the trustee learns about that person.¹

Who Has to Receive It

Every beneficiary of the trust (or of the portion that became irrevocable) must be notified. When the trigger is the settlor’s death, or a death-related contingency within a year of death, the trustee must also notify each of the settlor’s heirs.¹

“Heir” has a specific meaning here. It is anyone who would have inherited from the settlor under California’s intestacy laws if the trust did not exist or were invalid. That sweeps in people the trust may have left out on purpose. A disinherited child, an estranged sibling, a relative who gets nothing under the trust document still has to be notified, because they still have standing to challenge the trust. The trustee cannot quietly skip them.

Two narrow exceptions apply. The trustee need not notify a person who cannot be located after a reasonable search, or one whose existence the trustee does not know about. If anyone later questions those omissions, the trustee has to be able to show the search effort was genuine.¹

What the Notice Must Contain

Subdivision (g) of the statute spells out what has to be in the document:

The name of the settlor and the date the trust was signed.
The name, mailing address, and telephone number of every current trustee.
The address of the place where the trust is principally being administered.
A clear statement that the recipient can request a complete copy of the trust’s terms from the trustee.¹

The Mandatory Boldface Warning

When the trust became irrevocable because of the settlor’s death or a death-related contingency, the notice has to include a warning about the contest deadline. The statute requires it to appear in its own paragraph, printed in at least 10-point boldface type or a reasonable equivalent, and the wording is prescribed: “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.”¹

If this warning is buried, shrunk, or paraphrased, a court can find the notice defective, in which case the 120-day clock may never have started running at all.

The 120-Day Deadline to Contest

Proper service of the notice starts a hard 120-day deadline to file a court action challenging the validity of the trust. This limitation applies when the notice was served because the trust became irrevocable at the settlor’s death.³

One extension exists. If the trustee delivers a copy of the trust terms to you during that 120-day window, you get 60 days from the delivery date, provided that date falls after the original 120-day mark. Whichever date is later controls.³

Miss whichever deadline applies and the right to contest is gone. Courts enforce the limit strictly. It is not a guideline, and there is no good-cause extension.

Recognized grounds for a contest are specific: the settlor lacked mental capacity when signing, someone exerted undue influence, the settlor was defrauded, the signature was forged or the document was not properly executed, or the settlor actually revoked the trust before death. Disappointment with the distribution is not itself a legal ground.

What to Do If You Received One

The notice looks like a routine letter. It is not. From the moment it is served on you, the clock is running.

Request a full copy of the trust in writing right away. You have the right to one, and you cannot sensibly decide whether to challenge a document you have not read. Write down the date the notice was served on you, because that is the date your 120-day window is measured from. If anything about the trust worries you, including the identity of the trustee, the distribution scheme, or the circumstances under which the settlor signed, talk to a trust litigation attorney well before the deadline. Investigating capacity, undue influence, or forgery takes time, and 120 days passes quickly.

If the Trustee Never Sends the Notice

A trustee who skips the notice, or sends a version that fails the statutory requirements, does not quietly close the matter. The 120-day deadline never starts. Potential challengers may have years rather than months to sue.

The exposure runs further than that. A trustee who distributes assets while the trust is still open to challenge risks personal liability if a later contest succeeds and unwinds those distributions. For anyone taking on the trustee role, sending a properly drafted notice is one of the first items of business, and most trustees get it reviewed by a probate attorney before mailing.

Waivers in the Trust Document Do Not Count

Some settlors try to write the notice requirement out of their trusts, usually to keep the terms private or to deter contests. California treats any such waiver as void and against public policy. A trustee who relies on waiver language and skips the notice ends up in the same position as one who forgot: the contest clock never starts and the trust stays exposed. The statute also does not reach back to triggering events that happened before January 1, 1998.¹
