How Do You Revoke a Trust in California?
If you want to revoke a trust in California, the starting point is California Probate Code § 15400: unlike the traditional common-law rule, California presumes every trust is revocable unless the trust instrument expressly says otherwise. That single presumption flips the default question bar candidates and practicing attorneys need to ask — not “did the settlor reserve a power to revoke,” but “did the settlor clearly give it up.”
This matters both on the exam and in practice. Estate planning clients frequently assume their trust can be undone with a phone call or a new will. The actual answer depends on the specific revocation method the trust instrument requires, and getting it wrong can leave an “irrevocable” trust standing when the settlor meant to cancel it.
What is trust revocation? Revocation is the settlor’s power to cancel a revocable trust during life and reclaim the trust property. California Probate Code § 15400 presumes revocability by default, while § 15401 governs the specific methods a settlor must use to exercise that power.
The Four Methods of Revocation Under § 15401
California Probate Code § 15401 recognizes several ways a settlor can revoke, though not every method is always available.
- Express written revocation. The settlor signs a writing declaring revocation and delivers it to the trustee. This is the most reliable and commonly used method.
- Testamentary revocation. The settlor can revoke through a will, unless the trust specifies an exclusive method that excludes this option.
- Any manner manifesting intent. Conduct that clearly shows an intent to revoke — closing an account, retitling assets — can suffice, though it’s less certain and often needs corroborating evidence.
- Partial revocation. A settlor can revoke only a portion of the trust; the rest continues under the original terms.
The Exclusive Method Trap
This is the single most heavily tested issue in this area, and it’s worth internalizing as a checklist item for any trust-revocation fact pattern.
If the trust instrument states that it “may be revoked only by a written instrument signed and delivered to the trustee,” that language creates an exclusive method. Once a trust specifies an exclusive method:
- A will attempting to revoke the trust fails, even though testamentary revocation is normally permitted.
- Conduct-based revocation (closing accounts, informal statements) fails.
- Only strict compliance with the specified method works.
By contrast, permissive language — “the trust may be revoked by written instrument” — does not create exclusivity. Other statutory methods remain available alongside it. Courts look for words like “only,” “solely,” or “exclusively” as the trigger; without that kind of restrictive language, § 15401’s other methods stay on the table.
| Trust language | Effect |
|---|---|
| “Revocable only by written instrument delivered to trustee” | Exclusive method — only that method works |
| “May be revoked by written instrument” | Non-exclusive — will, conduct, and other methods remain available |
| Silent on revocation method | California presumption of revocability applies; any § 15401 method is available |
Revocation vs. Modification
Revocation and modification are related but distinct powers, and bar essays sometimes test the difference directly. Revocation terminates the trust entirely and returns the property to the settlor (or the settlor’s estate, if the settlor has died). Modification changes specific terms while the trust continues to exist. A settlor who holds the power to revoke generally also holds the power to modify, unless the trust separately restricts modification. Don’t assume the two powers rise and fall together in every fact pattern — always check whether the instrument treats them separately.
When Is Revocation Effective?
Revocation becomes effective once the settlor manifests the required intent and, where the method demands it, delivers the writing to the trustee. If the trust requires delivery as part of its exclusive method, a signed-but-undelivered revocation document typically is not enough. Once revocation is effective, the trust terminates and the property reverts — during the settlor’s lifetime, back to the settlor; after death, into the settlor’s probate estate for administration.
Worked Example: Bar Exam Fact Pattern
Martina creates a revocable inter vivos trust in 2018 naming her daughter as trustee, and the trust instrument is silent about how it may be revoked. In 2025, Martina executes a valid will that includes language revoking the trust and directing that the trust assets pass under the will instead.
Analysis: Because the trust doesn’t specify an exclusive revocation method, California’s default rules apply, and testamentary revocation under § 15401 is available. Martina’s will validly revokes the trust, and the assets pass according to the will’s terms (subject to any pour-over or funding issues).
Change the facts: Suppose Martina’s trust instead states, “This trust may be revoked only by a written instrument signed by the settlor and delivered to the trustee during the settlor’s lifetime.” Martina’s 2025 will attempts to revoke the trust the same way. This time, the attempt fails — the exclusive method requires a signed writing delivered to the trustee during life, and a will executed and effective only at death cannot satisfy that requirement. The trust survives, and the will’s revocation clause is ineffective as to the trust.
Common Mistakes to Avoid
Bar candidates often assume every revocable trust can be revoked by any method, forgetting that exclusive-method language changes the analysis entirely. Others apply the outdated common-law presumption of irrevocability instead of California’s statutory presumption of revocability. A third recurring error: assuming partial revocation terminates the whole trust, when in fact the untouched portion continues under its original terms.
FAQ
Does California presume a trust is revocable or irrevocable?
California presumes every trust is revocable unless the instrument expressly states it is irrevocable. This is the opposite of the traditional common-law default.
Can a will revoke a California trust?
Usually yes, under Probate Code § 15401 — unless the trust names an exclusive revocation method that doesn’t include testamentary revocation. If the trust requires only a written instrument delivered to the trustee, a will cannot revoke it.
Can a settlor revoke only part of a trust?
Yes. Partial revocation is permitted; the settlor reclaims the revoked portion while the remaining trust property continues to be governed by the original terms.
Key Takeaways
- California Probate Code § 15400 presumes trusts are revocable; irrevocability must be stated expressly.
- Probate Code § 15401 recognizes written revocation, testamentary revocation, conduct manifesting intent, and partial revocation.
- Exclusive-method language (“only,” “solely,” “exclusively”) locks the settlor into a single revocation method and defeats all others.
- Revocation terminates the trust; modification changes it while it continues — the two powers usually travel together but aren’t identical.
- Watch for exclusive-method traps on the bar exam whenever a fact pattern shows a settlor using a different method than the one the trust specifies.
