A Certification of Trust in California is a short, notarized document a trustee uses to prove the trust exists and that they have authority to act, without handing over the full trust instrument. It is governed by California Probate Code Section 18100.5, which lists exactly what the certification must contain and forbids anyone from demanding the trust’s distribution terms as a condition of doing business. Banks, title companies, and brokerages accept it in place of the trust itself.
When Trustees Are Asked for One
Almost any institution that touches trust-held assets will want proof the trustee can act. Banks ask when you open or retitle accounts. Title companies require one during real estate closings. Brokerage firms want it before allowing trades in a trust’s investment accounts. Without the certification, these institutions would otherwise need to review the full trust, which is often dozens of pages of provisions unrelated to the transaction in front of them.
The certification does two jobs at once. It gives the third party a concise confirmation of the trustee’s authority, and it keeps the trust’s private terms private. Specific bequests and family arrangements stay out of view because the statute bars the certification from including them.
What the Certification Must Contain
Section 18100.5 lists eight categories of information the certification may include, and in practice institutions expect all of them. The document should confirm:
- The name of the trust and the date the original trust instrument was signed.
- The names of the settlors who created the trust and the names of all currently acting trustees.
- The trustee’s relevant powers, or a broader statement that the trustee holds all powers necessary for the transaction.
- Whether the trust is revocable or irrevocable, and the name of anyone who holds the power to revoke it.
- If more than one trustee serves, whether all of them or fewer than all must sign to exercise the trustee’s powers.
- The trust’s taxpayer identification number, whether a Social Security number or an EIN.
- The manner in which title to trust assets should be taken.
- A legal description of any real estate the trust holds.
The certification must also state that the trust has not been revoked, modified, or amended in any way that would make its representations incorrect, and it must state that all currently acting trustees are signing it.
One small trap: the statute does not require the trustee’s address, even though many form templates include an address field. Including it is fine, but leaving it off is not a defect.
What Stays Out
The statute draws a firm line around the trust’s dispositive provisions, meaning the sections that spell out how the trust estate gets distributed, who inherits what, and under what conditions. A certification cannot be required to contain any of that. This applies whether the requester is a bank, a title company, or anyone else.
The trustee may choose to attach excerpts from the trust or its amendments, along with documents showing succession of trustees. That choice belongs to the trustee. No third party can demand the full trust instrument or the distribution terms as a condition of the transaction.
Signing and Notarization
Every currently acting trustee must sign. If the trust has three cotrustees, all three sign, and the document must say that all currently acting trustees are signing it.
The statute requires the certification to be “in the form of an acknowledged declaration.” An acknowledgment is a specific notarial act: the signer appears before a notary, proves identity, and confirms they voluntarily signed the document. The notary then attaches an acknowledgment certificate. California provides a standard acknowledgment form for this. The notary is verifying identity, not vouching for the accuracy of anything in the certification.
The same process applies to a successor trustee stepping in after the original trustee dies or becomes incapacitated. The successor signs a new certification as the currently acting trustee, and may include excerpts from documents showing how they obtained authority.
Recording When Real Property Is Involved
If the trust holds real property, the signed certification can be recorded with the county recorder in the county where the property sits. Recording is not required for every transaction, but title companies handling a sale or refinance typically want the certification on record to establish a clean chain of title. Recording fees vary by county.
When a Third Party Can Ask for More
The certification is designed to be self-contained, but it is not absolute. Under subdivision (e) of Section 18100.5, a person whose interest could be affected by the certification may require the trustee to provide excerpts from the trust document. Those excerpts are limited to two categories: documents showing the trustee’s succession, and provisions giving the trustee power to act in the specific pending transaction.
This is narrow. A third party can see the clause granting the trustee authority to sell real property, for example, but cannot use this provision to demand the full trust or its distribution terms. The statute repeats that limit explicitly.
Protections for Third Parties and Penalties for Overreach
Anyone who acts on a certification of trust in good faith, without actual knowledge that its statements are incorrect, has no liability for doing so. They can treat the facts in the certification as true without investigating the underlying trust. Any transaction entered into based on the certification is enforceable against the trust’s assets. If a title company closes a sale and a lien is created in reliance on the certification, that lien is valid even if something later turns out to be wrong, as long as the third party had no actual knowledge of the problem.
The statute also pushes back the other way. If a third party demands the full trust after receiving an acceptable certification, and a court later determines that demand was made in bad faith, the person who refused the certification is liable for the trustee’s damages, including attorney’s fees. This does not apply when a beneficiary requests trust documents or in trust litigation, where broader disclosure rules govern.
Keeping the Certification Accurate
The statute sets no expiration date and does not require a new certification after every amendment. But the document itself declares that the trust has not been changed in any way that would make its representations incorrect. That built-in accuracy requirement means the certification becomes unreliable the moment the trust is amended in a way that changes any certified fact: a new trustee is named, the trust becomes irrevocable, the powers change, or real property is added or removed.
Prepare a new certification whenever the trust goes through a meaningful amendment. An institution that spots a stale certification with outdated trustee names or powers will refuse to proceed, and re-executing the document costs far less than the delay of being turned away at a closing.
