California Certificate of Trust Requirements

A California certification of trust may confirm any of the facts or contain any of the information listed in Cal. Prob. Code § 18100.5(b). It must state that the trust has not been revoked, modified, or amended in a manner that would make the certification’s representations incorrect, state that it is being signed by all currently acting trustees, and be in the form of an acknowledged declaration signed by all currently acting trustees (§ 18100.5(c)). It need not disclose the trust’s dispositive provisions (§ 18100.5(d)). A person who relies on the certification without actual knowledge that its representations are incorrect receives the protections described in § 18100.5(f).

California Probate Code § 18100.5: summary and official text

The certification-of-trust mechanism sits in Division 9’s Part 6 (“Rights of Third Persons”), Chapter 2 (“Protection of Third Persons”), Cal. Prob. Code §§ 18100–18108 — the same chapter, not a separate title, that supplies California’s general good-faith protection for third persons dealing with a trustee (§ 18100). Section 18100.5 itself was last substantively amended by Stats. 2004, Ch. 136, effective January 1, 2005, which added the recording language now in subsection (c) and the companion affidavit-of-change-of-trustee provisions in §§ 18105–18108 discussed below. California has not enacted the Uniform Trust Code (UTC § 1013’s certification-of-trust provision has no direct California counterpart); § 18100.5 is California’s own, freestanding scheme.

California’s statute uses the term certification of trust. “Certificate of trust” and “affidavit of trust” are practice terms, not the statutory one, though they are used interchangeably by title companies and financial institutions.

Permitted and required content

Section 18100.5(c) contains the certification’s mandatory content and execution requirements. The certification must state that the trust has not been revoked, modified, or amended in a manner that would make its representations incorrect, state that it is being signed by all currently acting trustees, and be in the form of an acknowledged declaration signed by all currently acting trustees. An acknowledgment is commonly taken before a notary public, but California Civil Code § 1181 also authorizes certain other officers to take an acknowledgment within California.

The same chapter supplies a related but distinct tool. If title to an interest in real property is affected by a change of trustee, § 18105 permits the successor trustee to execute and record an affidavit of change of trustee in the county where the property is located. The affidavit must include the property’s legal description, the names of the former trustees, and the names of the successor trustees. It may also include excerpts from the trust instrument, amendments, and other documents concerning the succession of trustees. Sections 18106–18108 address recording and indexing, the affidavit’s evidentiary effect, and requests for documents concerning the trustee’s succession.

A certification of trust under § 18100.5 and an affidavit of change of trustee under § 18105 therefore serve different purposes and have different content requirements.

Where the statute is silent

Chapter 2 as researched sets no deadline for a recipient to accept or act on a certification once furnished, and § 18100.5 supplies no statutory form or form safe harbor. The chapter also does not address remote online notarization for the acknowledgment required under subsection (c) — California’s RON authority sits in the Government Code and Civil Code, outside this chapter, and was not part of this research. And while § 18100.5(a) does not by its terms limit the certification device to California trusts, the researched sections of Division 9 do not include a conflict-of-laws or trust-validity provision addressing recognition of an out-of-state trust’s certification; that answer likely lives elsewhere in the Probate Code and was outside the scope of the sections fetched for this page.

What a recipient may demand, and reliance and refusal liability

What a recipient may demand. Under § 18100.5(e), a person whose interest is or may be affected may require the trustee to provide copies of excerpts from the original trust documents, amendments, and other documents that designate, evidence, or pertain to the succession of the trustee, or that confer the power to act in the pending transaction — or both. The subsection is explicit that nothing in it requires or implies an obligation to provide the trust’s dispositive provisions, or the entire trust and its amendments.

Reliance protection runs two ways. Under § 18100.5(f), a person who acts in reliance on a certification without actual knowledge that its representations are incorrect is not liable to anyone for so acting, and may assume without inquiry that the certified facts exist; actual knowledge is not inferred merely because the person holds a copy of all or part of the trust instrument. Any transaction — and any lien it creates — entered into in reliance on the certification is enforceable against the trust assets, unless the person had actual knowledge the trustee was acting outside the scope of the trust. Nothing in the section limits a beneficiary’s own rights against the trustee.

Failing to demand a certification isn’t held against anyone. Section 18100.5(g) provides that a person’s failure to demand a certification of trust does not affect the good-faith protection available under § 18100, and no inference about good faith may be drawn from not demanding one.

The fee-shifting provision targets the demand for documents, not a refusal to transact. Under § 18100.5(h), a person who — outside the beneficiary and litigation contexts, and subject to subsection (e) — demands the trust documents in addition to a certification acceptable to the third party is liable for damages, including attorney’s fees, if a court finds the demand was made in bad faith. California’s carve-out for demands made by a beneficiary or in the context of litigation concerning the trust is a nuance worth flagging: the fee-shifting protection is narrower than a blanket rule, and does not reach every situation where a recipient insists on more than the certification.

Recording. Any person may record a certification relating to an interest in real property in the county where all or part of the property is located (§ 18100.5(i)). The county recorder may impose the recording fee prescribed by law, and the recorded certification becomes a public record of the real property involved. Section 18100.5(i) expressly provides that it does not create a requirement to record a certification in conjunction with the recordation of a transfer of title involving a trust.

Certifications and out-of-state trusts

Section 18100.5 does not by its own terms restrict the certification device to trusts created under California law, and nothing in the chapter conditions a certification’s validity on where the underlying trust was formed. That said, the sections of Division 9 fetched for this page do not include a provision addressing choice of law or the validity of a trust created under another jurisdiction’s law, the way some states’ trust codes do explicitly. A practitioner relying on a California certification of trust for a foreign trust — or presenting an out-of-state certification to a California institution — should confirm the underlying trust’s validity and situs under whichever Division 9 provisions govern that question, which sit outside the sections researched here.

The certification is only as reliable as the trust behind it — see the California revocable living trust requirements page for how a California trust is created, revoked, and amended, including the § 15401(c) limit on an agent’s authority to touch the trust. Where an agent under a power of attorney is the one transacting on the trust’s behalf, the California durable power of attorney requirements page covers the express-grant requirement in Cal. Prob. Code § 4264(a) that has to line up with whatever the trust instrument itself permits.

Because a California certification may recite trustee powers, revocability, cotrustee signing rules, and other facts from the underlying instrument, any representations it contains should match the trust. Section 18100.5(c) also requires the certification to state that the trust has not been revoked, modified, or amended in any manner that would cause its representations to be incorrect. This is a case where deterministic drafting that generates the certification from the same intake record as the trust itself helps keep the documents aligned.
