Acknowledgment for Representatives

A woman appears at your desk to sign a grant deed. The signature line reads "Mary Johnson, as Attorney-in-Fact for Robert Johnson." She presents her own driver's license showing "Mary Johnson." The deed will transfer Robert's property—but Robert isn't here. Do you compare Mary's ID to Robert's name? No. You identify Mary, because she is the one appearing before you and signing.

This scenario illustrates one of the most frequently tested—and confused—areas of notary practice: representative capacity signings.

What Is Representative Capacity?

A person signs in representative capacity when they sign on behalf of someone else—an individual, corporation, trust, partnership, or other entity.

Capacity TypeSigning On Behalf OfAuthority Document

Corporate OfficerA corporationCorporate resolution/bylaws

The Critical Rule: WHO Do You Identify?

This is the most tested point regarding representative capacity:

IdentifyDo NOT Identify
The person appearing before youThe person they represent (the principal)
The representative who is signingThe corporation, trust, or principal
The attorney-in-factThe person who granted the power

Exam Answer: Always identify the representative—the person physically appearing before you.

Real-World Example:

  • Mary Johnson appears as attorney-in-fact for Robert Johnson
  • You verify Mary's identity (not Robert's)
  • Mary signs the document
  • Mary acknowledges she signed on behalf of Robert

What the Notary Does NOT Verify

NOT Your ResponsibilityWhy
Whether the POA is validLegal determination
Whether the representative has authorityLegal determination
Whether the principal is aliveYou have no way to know
Whether the representative is acting properlyNot your role

Key Point: You are not a legal gatekeeper. Your job is to identify the signer and take the acknowledgment.

The Acknowledgment Form's Representative Capacity Language

The California all-purpose acknowledgment includes language specifically for representative capacity:

PhrasePurpose
"in his/her/their authorized capacity(ies)"Indicates signing in a capacity
"the entity upon behalf of which the person(s) acted"Covers corporate, trust, partnership signings
"executed the instrument"Confirms the signing on behalf of the principal/entity

On the Exam

Expect 2-3 questions on representative capacity. Key points tested:

  • Identify the REPRESENTATIVE: The person physically appearing, not the principal
  • Authority verification NOT required: You don't determine if they have authority
  • Common capacities: Attorney-in-fact, corporate officer, trustee, partner, executor
  • Certificate language: "in his/her/their authorized capacity(ies)"
