5.3 Acknowledgment for Representatives

Key Takeaways

  • A representative signs on behalf of another person or an entity such as a corporation or trust
  • The notary identifies the representative who appears — never the principal or the entity
  • Common capacities are attorney-in-fact, corporate officer, trustee, partner, and executor
  • The notary does NOT verify the representative's authority or whether a POA is valid
  • The 1189 form already includes the 'authorized capacity' language that covers representatives

The Question Examiners Love

Mary Johnson signs a grant deed as "Mary Johnson, as Attorney-in-Fact for Robert Johnson." The deed transfers Robert's property — but Robert is not present. Whose ID do you check? You identify Mary, the human being standing in front of you. This is the most confused area of representative practice, and the California exam tests it almost every administration.

What Representative Capacity Means

A signer acts in representative capacity when they sign for someone or something else — an individual, corporation, trust, partnership, or estate. The signature line names both the signer and whom they represent.

CapacitySigns on behalf ofAuthority comes from
Attorney-in-factAn individual (the "principal")A power of attorney
Corporate officerA corporationBylaws or board resolution
TrusteeA trustThe trust agreement
General/limited partnerA partnershipThe partnership agreement
Executor/administratorA decedent's estateLetters testamentary or court order
Guardian/conservatorA minor or incapacitated personA court order

Five Capacities Worth Memorizing

  • Attorney-in-fact — an agent under a power of attorney. Crucially, an attorney-in-fact is not necessarily a lawyer; it can be a daughter managing an elderly parent's affairs. Example signature: "Mary Johnson, as Attorney-in-Fact for Robert Johnson."
  • Corporate officer — president, vice president, secretary, treasurer, CEO, or CFO. Example: "Jane Doe, President of ABC Corporation."
  • Trustee — manages trust property. Example: "Robert Brown, Trustee of the Brown Family Trust."
  • General partner — binds the partnership. Example: "Sarah Wilson, General Partner of XYZ Partners."
  • Executor/administrator — handles a decedent's estate. Example: "Tom Adams, Executor of the Estate of William Adams, Deceased."

The Core Rule: Identify the Person Who Appears

You identifyYou do NOT identify
The representative physically before youThe absent principal
Mary, the attorney-in-factRobert, the principal
The corporate officer signingThe corporation itself

Identity verification attaches to a living, present human. A corporation cannot present a driver's license, and an absent principal cannot personally appear. So you collect satisfactory evidence for the representative, the representative makes the acknowledgment, and the journal records the representative's name and (for real-property documents) the representative's thumbprint.

What You Must NOT Investigate

This is where well-meaning notaries overstep. You are not a legal gatekeeper.

Do NOT determineReason
Whether the power of attorney is validLegal determination — outside notary authority
Whether the officer or trustee truly has authorityThe 1189 form forbids you from certifying capacity
Whether the principal is still aliveYou have no way to know
Whether the agent is acting in good faithNot a notarial function

In fact, on documents going out of state, Civil Code 1189 specifically bars you from completing any form that would require you to certify the signer holds a particular representative capacity. You note the capacity the signer claims; you do not vouch for it.

The Form Already Handles It

You do not need a special representative certificate. The all-purpose 1189 form already contains the language that covers any capacity:

  • "...acknowledged to me that he/she/they executed the same in his/her/their authorized capacity(ies)..."
  • "...that by his/her/their signature(s) on the instrument the person(s), or the entity upon behalf of which the person(s) acted, executed the instrument."

You simply fill in the representative's name as it appears on the document and select the correct pronouns.

A Worked Scenario

A corporate officer, Jane Doe, appears to acknowledge a commercial deed of trust signed "Jane Doe, President of ABC Corporation." You ask for Jane's current passport, confirm her name matches the signature line, and take her acknowledgment. You do not ask for the board resolution authorizing the financing, you do not call the corporation, and you do not decide whether a president may bind ABC Corporation — those are legal questions. Because the deed of trust affects real property, you record Jane's right thumbprint and a journal entry under Jane Doe's name, noting the capacity she stated.

The acknowledgment certificate lists her name as it appears on the document, and the 1189 "authorized capacity" and "entity upon behalf of which the person acted" language does the rest.

Now change the facts: the document is a power of attorney that Robert Johnson signed last week granting Mary authority. Mary brings it to you to acknowledge Robert's signature on his behalf — that does not work. Robert is the signer of the POA and must personally appear to acknowledge his own signature; Mary cannot acknowledge for him. Identity and acknowledgment always track the person who actually signed and appears.

A Common Trap

Notaries sometimes feel they should protect the principal by demanding proof of authority. Resist this instinct. Refusing to notarize because you doubt an agent's authority — when identity and the other requirements are satisfied — can itself expose you to liability and is not a valid ground to decline. Your gatekeeping is limited to identity, willingness, competence, and the absence of obvious coercion or incompleteness.

On the Exam

Expect 2-3 questions. The answers almost never change: identify the representative who appears (not the principal or entity); you do not verify authority or whether the POA is valid; the standard capacities are attorney-in-fact, corporate officer, trustee, partner, and executor; real-property documents still require the representative's thumbprint and journal entry; and the 1189 "authorized capacity" language already accommodates every representative signing.
