To amend a living trust in California, you prepare a written document that names the original trust, states which provisions you are changing, is dated and signed by you as the settlor, and is delivered to the trustee during your lifetime. There is no official trust amendment form issued by the state of California; the amendment is a document you draft yourself (or with an attorney) that must follow either the amendment procedure written into your trust or the fallback procedure in the Probate Code.
Can You Amend Your Trust
If your trust is revocable, yes. Under California Probate Code Section 15402, unless the trust says otherwise, a settlor can modify a revocable trust using the same procedure available for revoking it. That covers adding or removing beneficiaries, changing a successor trustee, adjusting distributions, or almost any other change, as long as you are mentally competent when you sign.
Competence here tracks the standard used for wills: you need to understand what you are doing, know the nature of your property, and recognize the people affected by your decisions. If the amendment is later challenged, that is the question a court will ask about the moment you signed.
Irrevocable trusts are different. Because you gave up control over the assets, changes require either the written consent of the settlor and every beneficiary, or a court order. If a beneficiary refuses to consent, the settlor and the remaining beneficiaries can petition the court to modify the trust, but only if the change does not substantially harm the interests of the person who refused.1Justia. California Code Probate 15400-15414 – Modification and Termination of Trusts Beneficiaries acting alone can also petition, but a court will not approve modification or termination if it would defeat a material purpose of the trust.
Read Your Trust’s Amendment Clause First
Before you draft anything, read your original trust. Many trusts include their own instructions for how amendments must be made: notarization, one or two witnesses, delivery to the trustee within a set time. California law lets the settlor set those rules, and when the trust spells out a procedure, that procedure controls.2California Legislative Information.

Is the Trust’s Method the Only Method
California provides a statutory fallback: a writing signed by the settlor and delivered to the trustee is enough to amend a revocable trust, even if the trust itself describes a different procedure.2California Legislative Information. California Code Probate Code 15401 – Revocation of Trust The exception: if the trust explicitly makes its procedure the exclusive method, the statutory fallback is not available. The trust has to use unmistakable language, such as “only by,” “exclusively,” or “no other method shall be effective.” Vague language or the mere presence of an amendment clause does not lock you in.
The California Supreme Court addressed this in Haggerty v. Thornton, holding that when a trust describes a procedure but does not declare it exclusive, the settlor can use either the trust’s method or the statutory method. That said, following your trust’s procedure when you can is the safer route, because it eliminates any argument later about which method applied.
When the Trust Says Nothing
If your trust is silent, the statutory method fills the gap. You need a written instrument (not a will), signed by you, and delivered to the trustee during your lifetime.2California Legislative Information. California Code Probate Code 15401 – Revocation of Trust If you are your own trustee, delivery to a separate person is not required, but keep the signed amendment with your trust documents so your successor trustee can find it.
What the Amendment Document Should Contain
The amendment is a standalone document that ties into and modifies the original. Keep it precise. Leave no room to argue about which provisions changed.
- A clear title, such as “First Amendment to the [Your Full Name] Revocable Living Trust.” Number subsequent amendments in order so the trust’s history reads cleanly.
- The formal name of the trust and the exact date the original was signed. Reference the dates of any prior amendments.
- A statement that you are the settlor, that the trust is revocable, and that you are exercising your power to amend under the trust or under Probate Code Section 15401.
- The specific changes, identified by article, section, or paragraph number, stating whether you are replacing, deleting, or adding language. For a replacement, use wording like “Article Four, Section B is deleted in its entirety and replaced with the following,” and then set out the new text. Vague descriptions invite disputes.
- A reaffirmation clause stating that all provisions of the original trust not changed by this amendment remain in full force. This prevents an argument that an unmentioned provision was accidentally revoked.
Do not try to make one amendment do too much. If you are rewriting a third or more of the trust, a restatement is a better tool.
Signing, Notarizing, and Delivering
The amendment must be in writing and signed by the settlor. That is non-negotiable under the statute.2California Legislative Information. California Code Probate Code 15401 – Revocation of Trust Date the document so the effective moment is clear.
Notarization is not required by statute for most trust amendments, and California courts have enforced non-notarized amendments where the trust did not make notarization exclusive. Even so, notarization is cheap insurance. A notarized signature is much harder to challenge later, and if the amendment touches real estate held in the trust, you will need notarization to record any new deeds with the county.
If your trust document requires witnesses, have them present at signing. Even when it does not, a witness or two can help fend off a later capacity challenge.
After signing, deliver the amendment to the trustee. If you are both settlor and trustee, delivery means keeping the amendment with the trust documents. If someone else serves as trustee, hand them a copy or send it in a way that gives you proof of receipt. The statute requires delivery during your lifetime for the amendment to be effective.2California Legislative Information. California Code Probate Code 15401 – Revocation of Trust
When a Restatement Is the Better Tool
An amendment works well for targeted changes: swapping a beneficiary, updating a trustee, adjusting a percentage. Once you have stacked three or more amendments on the original, your successor trustee has to read every layer and reconcile them. Contradictions creep in.
A restatement replaces all the internal provisions while keeping the original trust intact as a legal entity. The trust keeps its original name, creation date, and tax identification number, and assets already titled in the trust do not need to be retransferred. The old provisions are simply superseded. Consider a restatement when your changes are extensive, when you have already amended the trust several times, or when you want a single clean document your successor trustee can follow without cross-referencing.
Joint Trusts and What Changes at a Spouse’s Death
Married couples in California often create a single joint revocable trust holding community property and sometimes separate property. While both spouses are alive and competent, most joint trusts require both signatures to amend, though some allow one spouse to act alone. Read the amendment clause.
After one spouse dies, that spouse’s share of the trust generally becomes irrevocable. The surviving spouse can usually still amend the provisions governing their own share, but not the terms controlling the deceased spouse’s share. California case law has treated community property in a joint trust as splitting into separate interests at the first death, which caps the survivor’s amendment power. If your joint trust is not clear on this, talk to an estate planning attorney before you try to amend it.
After You Sign
Store It With the Original
Attach the signed (and, if applicable, notarized) amendment to the original trust document. Your successor trustee needs the complete set. Keep them in the same secure location, and tell your successor trustee where to find them.
Retitle Assets and Update Beneficiary Designations
If the amendment adds new property to the trust, retitle those assets in the trust’s name. For real estate, that means recording a new deed with the county recorder. For bank and brokerage accounts, contact the financial institution to update the registration. Mentioning an asset in the amendment does not move it into the trust. Skip this step and the asset may pass through probate, defeating the point of the amendment.
If the amendment changes beneficiaries, review accounts that carry their own beneficiary forms: retirement accounts, life insurance, payable-on-death bank accounts. Those forms typically override the trust, so update them directly with the institution.
IRS Notice for a New Responsible Party
Most trust amendments trigger no IRS filings. You generally do not need a new Employer Identification Number just because you changed the trust’s terms; a change of trustee or a beneficiary’s name or address does not require a new EIN.3Internal Revenue Service. Publication 5845, Do You Need a New Employer Identification Number? However, if the amendment changes the trust’s “responsible party” (the person who controls or manages the trust’s assets), you must notify the IRS within 60 days by filing Form 8822-B. That most commonly happens when you name a new trustee.4Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business
