California Bar Agency
Last updated: May 2, 2026
Agency questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
Agency is the fiduciary relationship that arises when one person (the principal) manifests assent that another (the agent) shall act on the principal's behalf and subject to the principal's control, and the agent manifests assent or otherwise consents to so act (Restatement (Third) of Agency §1.01). A principal is bound to a third party on a contract entered by an agent if the agent acted with actual authority (express or implied), apparent authority, or the principal ratified the act. A principal is vicariously liable for an agent's torts committed within the scope of employment under respondeat superior, but generally not for the torts of independent contractors. California follows the Restatement framework with statutory overlays in the Corporations Code (e.g., Corp. Code §§17703.01, 16301 for LLC and partnership agency).
Elements breakdown
Formation of Agency
An agency relationship arises by mutual manifestations of consent that the agent will act on the principal's behalf and under the principal's control.
- Principal manifests assent to agent acting
- Agent acts on principal's behalf
- Agent subject to principal's control
- Agent manifests consent to act
- Both parties have capacity
Actual Express Authority
Authority the principal has expressly granted to the agent through words, written or oral, directly conferring power to act.
- Principal's manifestation directed to agent
- Agent's reasonable understanding of scope
- Act falls within words used
- Authority not revoked at time of act
Common examples:
- Written power of attorney
- Board resolution authorizing officer to sign
- Oral instruction to purchase specific equipment
Actual Implied Authority
Authority the agent reasonably believes she has based on the principal's conduct, custom, position, or what is necessary to accomplish the express task.
- Principal's manifestation to agent
- Agent's reasonable belief in authority
- Authority incidental to express task or position
- Acts customary for that role
Common examples:
- Manager's authority to hire support staff
- Authority to pay incidental expenses
- Authority customary to the position held
Apparent Authority
Authority that exists when the principal's manifestations to a third party cause the third party reasonably to believe the agent is authorized to act.
- Manifestation traceable to principal
- Third party's reasonable belief in authority
- Third party's reliance on belief
- Belief based on principal's conduct, not agent's
Ratification
After-the-fact adoption by the principal of an unauthorized act done on the principal's behalf, treated as if originally authorized.
- Agent purported to act for principal
- Principal had capacity when act done
- Principal has knowledge of material facts
- Principal manifests assent to be bound
- No intervening rights of third parties
Respondeat Superior (Vicarious Liability for Torts)
An employer is vicariously liable for tortious acts of an employee committed within the scope of employment.
- Employer-employee relationship exists
- Tort committed by employee
- Act within scope of employment
- Act foreseeable to or characteristic of work
Independent Contractor Distinction
A principal generally is not vicariously liable for torts of an independent contractor because the principal lacks right to control the manner of work.
- No right to control manner of work
- Distinct occupation or business
- Skill and tools supplied by worker
- Payment by job, not by time
- Limited duration of relationship
Common examples:
- Non-delegable duty exceptions
- Inherently dangerous activity exceptions
- Negligent selection of contractor
Fiduciary Duties of Agent
An agent owes the principal duties of loyalty, care, obedience, and disclosure arising from the fiduciary nature of the relationship.
- Duty of loyalty (no self-dealing)
- Duty of care (reasonable competence)
- Duty of obedience to lawful instructions
- Duty to account and disclose material facts
- Duty of confidentiality
Liability of Disclosed, Partially Disclosed, and Undisclosed Principals
An agent's personal liability on a contract turns on whether the principal's existence and identity were known to the third party at contracting.
- Disclosed: only principal liable
- Partially disclosed (unidentified): both principal and agent liable
- Undisclosed: both principal and agent liable
- Agent always liable if no authority and no ratification
Common patterns and traps
Agent's Self-Proclamation Trap
Distractors will suggest that an agent's own representations to a third party — such as a business card, an email signature, or a verbal claim of authority — create apparent authority. They do not. Apparent authority must trace back to a manifestation by the principal. The agent saying "I'm authorized" without any principal-side conduct is legally irrelevant for apparent authority purposes, though it may make the agent personally liable for breach of warranty of authority.
An answer choice reads: "The principal is bound because the agent told the third party she had authority to sign contracts up to $100,000."
Frolic vs. Detour Misclassification
Within respondeat superior, a minor deviation from the employer's business (a detour) keeps the act within scope, but a substantial deviation for the employee's own purposes (a frolic) takes it outside scope. Distractors flip the classification or treat any personal motive as automatically dispositive. Look for whether the deviation was substantial in time, distance, and purpose, and whether the employee had returned to the business mission when the tort occurred.
An answer choice reads: "The employer is not liable because the driver was running a personal errand at the time of the accident" — when the errand was a brief two-block detour to a coffee shop on the delivery route.
Independent Contractor Reflex
Candidates correctly recall that principals usually are not liable for independent contractors' torts and pick that answer reflexively, missing the non-delegable duty exception (e.g., duty to maintain safe premises for invitees), the inherently dangerous activity exception (e.g., blasting, demolition), and negligent selection or supervision claims that hold the principal directly (not vicariously) liable.
An answer choice reads: "The owner is not liable because the demolition company was an independent contractor" — when the work involved inherently dangerous blasting.
Undisclosed Principal Surprise
When the third party does not know a principal exists, the agent appears to be contracting in her own name. The agent is personally liable on the contract, but so is the undisclosed principal once discovered — the third party can elect to sue either (though not both to judgment in most jurisdictions). Distractors say only the agent is liable or only the principal is liable; the correct answer recognizes joint exposure with election.
An answer choice reads: "Only the agent is liable on the contract because she signed in her own name and never mentioned a principal."
Ratification Without Knowledge
Ratification requires the principal to know the material facts of the unauthorized act when she affirms it. Distractors will offer ratification based on conduct that occurred before the principal learned what the agent had done — for example, the principal accepting goods without realizing the agent ordered them at an inflated price. Without knowledge of the material facts, no valid ratification occurs.
An answer choice reads: "The principal ratified the contract by accepting the shipment" — when the principal did not learn of the unauthorized price markup until weeks later.
How it works
Start every agency question by identifying the relationship: who is the principal, who is the agent, and what kind of authority (if any) supports the act. Suppose Reyes Manufacturing, Inc. tells its purchasing manager, Patel, in writing, to buy up to $50,000 in steel from any supplier. That is express actual authority. If Patel also rents a forklift to unload the steel because that is customary for purchasing managers, that is implied actual authority — incidental to the express task. If Reyes Manufacturing's CEO routinely introduces Patel to vendors as "our buyer for all steel needs," and a vendor reasonably relies on that representation to extend $80,000 in credit, apparent authority binds Reyes even though the dollar cap was exceeded. If Reyes later accepts the steel knowing the order was for $80,000, that is ratification. For tort liability, ask whether the tortfeasor was an employee (control over manner of work) acting within the scope, or an independent contractor — the answer determines whether respondeat superior applies.
Worked examples
Is Liu Properties bound to the five-year lease?
- A Yes, because Tanaka had apparent authority based on her statement to Reyes Consulting's CEO that she had full authority to sign any lease.
- B Yes, because Tanaka's title as Property Manager on the business card created apparent authority sufficient to bind Liu Properties to any lease term.
- C No, because Tanaka's express authority was limited to two-year leases, and Reyes Consulting cannot rely on Tanaka's own statements to establish apparent authority for the longer term. ✓ Correct
- D No, because a property manager never has authority to bind a limited liability company to any lease without a separate written board resolution.
Why C is correct: Tanaka had express actual authority only for leases up to two years. Apparent authority requires a manifestation from the principal (Liu Properties) to the third party (Reyes Consulting); Tanaka's own statements to Reyes Consulting cannot create apparent authority. The business card identified Tanaka as Property Manager but said nothing about lease length, so reasonable reliance for a five-year term is doubtful. Liu Properties is not bound, though Tanaka may face personal liability for breach of warranty of authority.
Why each wrong choice fails:
- A: Apparent authority requires the principal — not the agent — to make the manifestation that creates the third party's reasonable belief. Tanaka's own claim of authority is the textbook fact pattern that cannot create apparent authority. (Agent's Self-Proclamation Trap)
- B: The title "Property Manager" plausibly supports apparent authority for routine management tasks (e.g., short-term leases), but it does not stretch to bind the principal to any lease term whatsoever. The business card was a manifestation from the principal, but a reasonable third party would not interpret it as unlimited leasing authority. (Agent's Self-Proclamation Trap)
- D: This overstates the rule. An LLC manager or agent can be bound by leases through express, implied, or apparent authority without a separate board resolution; nothing in California's LLC statutes requires a formal resolution for every leasing transaction.
Is Patel Plumbing vicariously liable for Garcia's negligence?
- A Yes, because Garcia was driving a company-owned vehicle when the accident occurred.
- B Yes, because Garcia was an employee, and any negligence by an employee during business hours is automatically within the scope of employment.
- C No, because Garcia was on a substantial personal frolic at the time of the accident and had not yet returned to his employer's business. ✓ Correct
- D No, because Patel Plumbing exercised reasonable care in hiring and training Garcia.
Why C is correct: A twelve-mile detour in the opposite direction to visit a girlfriend is a substantial deviation in distance, time, and purpose — a frolic, not a mere detour. Garcia had not yet returned to the route or resumed serving Patel Plumbing's business at the time of the accident, so the act was outside the scope of employment. Without a sufficient nexus to the employer's business, respondeat superior does not impose vicarious liability.
Why each wrong choice fails:
- A: Use of a company vehicle alone does not establish scope of employment. The vehicle is one factor, but the dispositive issue is whether the employee was advancing the employer's business or pursuing personal ends at the time of the tort. (Frolic vs. Detour Misclassification)
- B: There is no "automatic during business hours" rule. The scope-of-employment inquiry is fact-specific and turns on whether the act was of the kind the employee was hired to perform, occurred substantially within authorized time and space limits, and was motivated at least in part to serve the employer. (Frolic vs. Detour Misclassification)
- D: Reasonable care in hiring is relevant to direct negligent-hiring claims, not to respondeat superior. Vicarious liability is strict liability for the employer based on the employment relationship and scope, regardless of the employer's own care.
What is the most likely outcome?
- A Reyes Gallery loses, because as an undisclosed principal it has no rights under a contract its agent signed in her own name.
- B Reyes Gallery wins, because as an undisclosed principal it may enforce the contract its agent made on its behalf, subject to defenses the collector could have raised against the agent. ✓ Correct
- C Reyes Gallery wins, but only because the collector ratified the transaction by cashing the $75,000 check.
- D Reyes Gallery loses, because Kim lacked apparent authority to bind anyone other than herself.
Why B is correct: An undisclosed principal may enforce a contract entered into by its agent acting within the agent's actual authority, even though the third party did not know the principal existed. Kim acted on Reyes Gallery's behalf with actual authority, so Reyes Gallery — as the undisclosed principal — may enforce the contract subject to any defenses the collector could have raised against Kim personally. The collector's refusal to deliver at the agreed $75,000 price is a breach.
Why each wrong choice fails:
- A: This states the wrong rule. Undisclosed principals can enforce contracts made by their agents with actual authority; both the agent and the undisclosed principal have rights and liabilities on the contract once the principal's identity is revealed. (Undisclosed Principal Surprise)
- C: Ratification is the wrong doctrine here. Ratification applies when an agent acts without authority; Kim acted with actual authority, so the contract was valid from the start. Cashing the check is consistent with performance of an existing contract, not adoption of an unauthorized act.
- D: Apparent authority is irrelevant when the agent has actual authority. Kim was authorized by Reyes Gallery to acquire the sculpture, and an undisclosed principal scenario by definition involves no manifestations to the third party — apparent authority cannot exist. (Agent's Self-Proclamation Trap)
Memory aid
Authority sources: "E-I-A-R" — Express, Implied, Apparent, Ratification. For tort liability ask: "Employee in Scope?" If yes, principal is liable; if independent contractor, principal usually is not (watch for the non-delegable duty and inherently dangerous activity exceptions).
Key distinction
Apparent authority requires a manifestation from the principal to the third party; implied actual authority requires a manifestation from the principal to the agent. The agent's own statements about her authority cannot create apparent authority — only the principal's conduct can.
Summary
Agency binds a principal when the agent acts with express, implied, apparent authority, or by ratification; for torts, respondeat superior binds the principal for employees acting within the scope but generally not for independent contractors.

What's the most important distinction to remember for agency?
Apparent authority requires a manifestation from the principal to the third party; implied actual authority requires a manifestation from the principal to the agent. The agent's own statements about her authority cannot create apparent authority — only the principal's conduct can.
Is there a memory aid for agency questions?
Authority sources: "E-I-A-R" — Express, Implied, Apparent, Ratification. For tort liability ask: "Employee in Scope?" If yes, principal is liable; if independent contractor, principal usually is not (watch for the non-delegable duty and inherently dangerous activity exceptions).
What's a common trap on agency questions?
Confusing apparent authority (manifestation from principal to third party) with implied actual authority (manifestation from principal to agent)
What's a common trap on agency questions?
Treating an undisclosed principal's agent as automatically off the hook on the contract
