Agency relationships and authority

Identify the client, the agent, and the authority connecting them.

Relationship
Identify the principal before deciding which loyalty duties apply.
Authority
An ongoing assignment can still contain narrow limits on particular acts.
Reliance
Ostensible authority depends on the principal's conduct and the third person's reasonable action.

The principal authorizes the broker to act as agent. An affiliated salesperson performs licensed activities through the responsible broker. The broker's client and the other party to the transaction are not interchangeable roles.

Learning objectives

  • Distinguish a principal, agent, customer, and subagent.
  • Explain express, implied, and ostensible agency and ratification.
  • Separate an agency relationship from authority to sign a purchase contract.

Start with who represents whom

Identify the represented principal and responsible brokerage; receiving assistance or paying compensation does not by itself determine who receives fiduciary loyalty.

Agency is a legal relationship in which one person acts for another in dealings with third persons. The principal authorizes the representation; the agent undertakes it. In a typical listing, the seller is the principal and the brokerage is the seller's agent. The buyer is a third party to that relationship even though the listing salesperson answers the buyer's questions or unlocks the house.

The word customer is useful shorthand for someone receiving services without being the brokerage's represented client. A customer is still owed important duties. The distinction identifies who receives fiduciary loyalty; it never creates permission to mislead an unrepresented person.

In everyday speech, people call a salesperson their agent. For California licensing purposes, the salesperson performs licensed activities under a responsible broker. The broker is the contracting brokerage and may act through affiliated salespersons and broker associates. Follow that chain when a question describes several people in one office. Different salespersons working with opposing sides can place the same brokerage in a dual agency relationship.

Follow the brokerage relationship, not the conversation

Classify the scope of the job

Special, general, and universal describe the scope of an appointment, while the agreement can impose narrower spending or signing limits.

Before classifying an appointment, draw the relationship in words. Write "owner to brokerage" for the employment relationship, "brokerage to salesperson" for supervised performance, and "owner to buyer" for the proposed sale. This prevents a common mistake: assuming that because the salesperson participates in all three conversations, the salesperson has become a contracting principal in all three relationships.

Agency can also exist outside a purchase. A landlord may employ a property manager; a borrower may retain a mortgage broker; a business owner may hire a broker to sell a business opportunity. In each case, identify the person whose interests the professional undertakes to represent. The property type does not supply the answer. A warehouse broker can represent a tenant, landlord, purchaser, or seller depending on the engagement.

For example, an investor asks a broker for an estimate of rent for a building the investor might buy. A casual preliminary discussion differs from an undertaking to locate properties, evaluate terms, and negotiate for the investor. The more the broker undertakes to act on the investor's behalf, the less useful a casual label becomes. Required agreements and disclosures should be addressed when the relationship develops, rather than postponed because the parties have not yet chosen a property.

A special agent has authority for a particular transaction or purpose. A broker retained to market one property is the classic example. A general agent handles an ongoing category of business. A property manager who collects rents, arranges authorized repairs, and administers leases under a management agreement illustrates general agency within specified limits.

A universal agent has unusually broad delegated authority. It is a textbook category, not the ordinary consequence of hiring a real estate broker. Even broad authority remains subject to the governing instrument and acts the law permits someone to delegate.

These categories describe scope, not the agent's professional quality. A special agent can owe the same demanding fiduciary duties as a general agent. A general agent can still exceed authority by undertaking an action outside the management agreement, such as borrowing against the property.

A subagent acts for an agent in conducting the principal's business when properly authorized. Do not assume that every cooperating broker is the seller's subagent. A cooperating broker may represent the buyer. Determine the actual relationship from the parties' agreement and conduct, then verify the required disclosures.

Authority can be narrower than the assignment

An owner may authorize a manager to approve individual repairs up to $800 while reserving larger expenditures for written approval. The manager has a continuing general agency, but a $6,000 replacement project falls outside the stated spending power. The owner need not call the manager a special agent to impose that limit. Classification and specific limits must be read together.

Distinguish an authorization from a prediction. "My seller will probably take $640,000" predicts a decision; "My seller authorized me in writing to sign this acceptance" asserts delegated power. A third person should not treat the first statement as the second. Similarly, authority to transmit a principal's signed acceptance is different from authority to decide what the principal will accept.

Emergency circumstances can affect what reasonable action is necessary, but they do not create unlimited financial authority. A manager dealing with a burst pipe should act within the agreement, applicable law, and reasonable protective measures. The emergency does not justify purchasing an unrelated improvement or borrowing against the entire building. Examine whether the act served the authorized purpose and whether the supposed necessity actually explains its scope.

A management assignment still has spending limits

A fictional agreement authorizes ordinary repairs up to $900 per job. Larger work needs owner approval. What changes the authority analysis?

$640 ordinary repair
Replacing a failed valve is within the stated assignment and spending limit.Authorized on these facts.
$3,600 planned upgrade
The manager can contact the owner. Calling the work four $900 invoices does not change this one job.Obtain approval; do not enlarge the express limit.
Active flooding
There is no time to communicate with the owner, and immediate protective action is clearly in the owner's interest.Analyze the emergency exception, not a general power to renovate.
Civil Code 2320 requires both the principal's clear interest and lack of time to communicate. A convenient improvement is not the same as an emergency. Chapter sources
Cooperating on a lease does not identify the principal
Tenant's brokerage

Assume a written engagement to find warehouse space and negotiate for the tenant only; no subagency has been authorized.

Tenantclient
The brokerage undertakes tenant-side representation under the stated engagement.
Landlord's brokeragecooperation
Exchanging access, proposals, and market information does not itself convert the tenant broker into the landlord's subagent.
Referring brokerageintroduction
Introducing the tenant to this brokerage does not by itself make the referring broker the agent of every party in the lease.
Change the authorized undertaking and the classification may change. Follow assent, scope, and conduct, not the fact that two licensees worked on the same transaction. Chapter sources

How agency is created

Separate whether duties arose, whether a particular act was authorized, and whether a sufficient agreement supports compensation; these questions can have different answers.

An express agency arises from words: the principal explicitly authorizes the agent to act. A signed listing or buyer representation agreement provides clear evidence of the relationship, its scope, and its duration. An implied agency may arise from conduct and surrounding circumstances showing consent and an undertaking to act. A person's label for the relationship cannot necessarily overcome conduct inconsistent with that label.

Writing requirements still matter. General agency principles do not excuse compliance with California rules governing real estate compensation agreements, buyer representation agreements, or authority to execute certain contracts. Separate these questions:

  1. Did a relationship and corresponding duties arise?
  2. Does the agent possess authority for the particular act?
  3. Is there an enforceable agreement supporting the claimed compensation?

A broker may fail the third question even when the facts establish duties under the first. Conversely, a written listing may support compensation while granting no authority to sign a sale contract for the owner. An employment agreement to find a buyer is not itself a conveyance of the real estate.

Actual and ostensible authority

Trace actual authority to the principal's authorization and ostensible authority to the principal's appearances plus qualifying third-party reliance, not the agent's unsupported claim.

Actual authority comes from what the principal intentionally confers or intentionally or negligently allows the agent to believe has been conferred. Express directions are the easiest example. Incidental authority can include ordinary steps necessary to carry out an authorized task, provided the agreement and law do not prohibit them.

Ostensible authority concerns what the principal causes a third person reasonably to believe. The critical conduct is attributable to the principal. An agent cannot manufacture authority merely by announcing, "I can approve any price." A third person also cannot reasonably rely on supposed authority while ignoring clear limitations or contradictory information.

Suppose an owner repeatedly directs a tenant to deal with the property manager about routine repairs, and the manager has consistently authorized modest repairs with the owner's knowledge. The facts may support authority for another ordinary repair. They do not automatically establish authority to sell the building. The magnitude and nature of the act matter.

Agency by estoppel is often used to describe a situation in which a principal cannot deny a relationship the principal has caused another person reasonably to rely on. On an exam, look for a representation or course of conduct, reasonable reliance, and a resulting change in position. An unsupported claim by the supposed agent is insufficient.

Civil Code section 2334 limits liability based on merely ostensible authority to a person who acts in good faith, exercises ordinary care, and incurs a liability or parts with value in reliance on that appearance. Believing a manager has power is not the entire test. Identify what the principal communicated, what the third person knew, and what commitment or value followed.

Notice and responsibility

Agency also affects the legal consequences of information. Civil Code section 2332 attributes notice between principal and agent of matters either knows and ought to communicate in good faith with ordinary care and diligence. A client cannot necessarily avoid transaction consequences by saying that a significant notice reached the client's agent instead of the client personally. Specific contractual notice provisions and the facts still matter.

This rule creates a practical reason to establish communication procedures. If a buyer's agent receives a time-sensitive seller response, the agent should identify what it requires, notify the buyer promptly, and document delivery. Storing it unread until the next weekly call is not a method of preserving the buyer's rights. Nor should a client deliberately route unwelcome information through an agent hoping it will remain legally invisible.

The same reasoning does not mean every fact learned by every employee anywhere is automatically known by every principal for every purpose. Scope, relevance, duties to communicate, and applicable exceptions remain important. Exam questions usually supply a clear connection between the information, the agent's work, and the client's transaction.

A material response cannot wait in the agent's inbox

A buyer's agent receives a material seller response within the agency. Assume the response is genuine; any formal contractual delivery issue must be checked separately.

  1. 10:00 a.m.
    Agent learns

    The response affects a decision the buyer must make that afternoon.

  2. Promptly
    Duty to communicate

    Ordinary care and good faith call for relaying the response and its significance, using a reasonable follow-up if the buyer does not respond.

  3. Before the decision point
    Principal decides

    The buyer evaluates the actual terms. The agent does not substitute a private decision that the response is unimportant.

Section 2332 can attribute notice of information the agent ought to communicate. Keeping the buyer uninformed does not safely postpone the consequences.

Imputed knowledge and compliance with an agreed notice method are different issues. This illustration does not declare that every email legally starts every contract clock. Chapter sources

Compare two unauthorized promises

Suppose a leasing manager tells a contractor that the owner approved a $7,000 renovation, although the owner's written limit is $1,000. In Case A, the owner has never suggested broader authority and the contractor has a copy of the limit. In Case B, the owner previously introduced the manager as the person authorized to approve renovations of that scale and knowingly allowed that practice to continue. The same private limit does not create identical third-party reliance in both cases.

Case A weakens an ostensible-authority argument because the contractor knows the restriction. Case B requires examination of what the owner's own conduct reasonably communicated. Neither case can be answered merely by quoting the manager's job title. If the owner later learns the full terms and validly adopts the renovation, ratification presents a further, separate route to analyzing the obligation.

For each variation, name the source of the claimed authority: actual authorization, the principal's appearance of authorization, or later ratification. Then ask whether the law requires a writing. Keeping those sources separate is more reliable than assuming every apparently useful act binds the owner.

The contractor has the restriction in writing

Repair approval file: fictional excerpts

A contractor wants the owner to pay for a $5,500 replacement ordered by a manager.

  1. Owner's emailManager may approve work up to $1,000. Send larger estimates to me.

    The contractor receives the restriction before agreeing to the replacement.

  2. Manager's messageDo not worry about the limit; I can approve everything.

    The agent's assertion alone does not create broader authority from the principal.

  3. Owner's conductNo broader holding out and no later approval are shown.

    The facts do not supply principal-created appearance or subsequent ratification.

  4. Changed factOwner personally approves this estimate before work begins.

    Now examine that actual approval rather than trying to rely on an appearance contradicted by the written limit.

A third party cannot disregard a known restriction and turn the agent's confidence into the owner's authorization.

For an ostensible-authority question, inspect evidence from the principal and what the third party knew when committing to the transaction. Chapter sources
Authority: whose conduct creates the belief?
Actual authority
  • The principal actually grants authority.
  • Identify the authorized act and its limits.
Ostensible authority
  • The principal's conduct creates the relevant appearance.
  • The agent's unsupported claim of power is not enough by itself.
Ask what the principal authorized or caused a third party reasonably to believe. Authority to market a property is not automatically authority to sign its purchase contract. Chapter sources
Reasonable reliance must precede the commitment

The owner has repeatedly directed a vendor to accept the manager's ordinary repair orders. Assume no actual authority for the disputed new order.

  1. Monday
    Appearance created

    The owner's communications and past conduct suggest authority for this class of repair.

  2. Tuesday, case A
    Vendor commits

    Without contrary notice, the vendor exercises ordinary care and incurs a payment obligation for materials relying on that appearance.

  3. Changed case B
    Restriction arrives first

    Instead, the vendor receives the owner's restriction before committing, then proceeds solely on the manager's assurance.

Case A supports the statutory reliance inquiry. Case B changes the knowledge and ordinary-care facts; the same job price does not produce the same result.

Civil Code 2334 requires good-faith reliance without lack of ordinary care and liability incurred or value given. A belief without the required reliance is incomplete. Chapter sources

Ratification and powers of attorney

Ratification requires informed adoption with applicable formalities; a power of attorney grants only its stated powers and does not confer a professional law license.

Ratification is informed adoption of an act initially performed without adequate authority. A principal who knows the material facts and accepts a transaction's benefits may ratify it, depending on the circumstances and required formalities. Ratification is not a device for validating an illegal transaction or ignoring a required written authorization. A principal also cannot deliberately accept the favorable part of an indivisible transaction while rejecting its burdens.

A power of attorney authorizes an attorney-in-fact to act within the instrument's terms. The attorney-in-fact need not be an attorney-at-law. Authority to execute real estate documents should be verified carefully, including scope, effectiveness, revocation, and any recording requirements relevant to the transaction.

A standard listing authorizes brokerage services. It does not ordinarily allow the broker to execute a purchase agreement or deed for the seller. Where the statute of frauds requires a transaction to be in writing, the equal dignities principle can require the agent's authority to enter it to be written as well. Never infer signing authority from possession of keys, an advertising budget, or a commission agreement.

Ratification includes the indivisible bargain
Fictional educational excerpt / Not for execution

Unauthorized purchase: fictional decision file

Assume an ordinary personal-property purchase for the managed building, oral authority would suffice, and the owner has capacity and full knowledge.

  1. Unauthorized bargainOne indivisible $820 package: cleaning machine plus required service plan.

    The manager had no original authority. The package is expressly not separable into independent contracts.

  2. Material informationOwner receives the complete price and service-plan terms.

    Informed adoption requires the material transaction facts, not merely knowledge that equipment arrived.

  3. Owner's proposed responseI adopt the purchase but reject the service-plan burden.

    Ratifying part of this indivisible transaction ratifies the whole under Civil Code 2311.

  4. Writing variantThe unauthorized act instead involves a contract requiring written authority.

    Apply the ratification formalities required for that act; benefit retention is not a universal substitute for a writing.

The owner must evaluate the whole package. Ratification does not mean selecting benefits while discarding inseparable obligations.

The teaching assumptions isolate Civil Code 2310 and 2311; ratification also cannot override other limits on validity or prejudice protected third-party rights. Chapter sources
Read the granted power, not the document label
Fictional educational excerpt / Not for execution

Limited authority: fictional teaching excerpt

This is not a power-of-attorney form. Assume a valid, currently effective instrument and no separate grant of authority.

  1. Named representativeAvery, attorney-in-fact for the owner.

    Attorney-in-fact describes a representative role; it does not establish that Avery is an attorney at law.

  2. Express powersCollect rents and order ordinary maintenance at 18 Pine Street.

    These management powers identify the acts the owner granted.

  3. Express restrictionNo power to sell, mortgage, or sign a deed.

    Broad wording such as "manage all matters" does not erase this specific limitation.

  4. Proposed actAccept a purchaser's offer and sign for the owner.

    That act is outside this excerpt. Obtain and verify appropriate authority rather than infer it from the title.

The correct question is whether the instrument authorizes this act now, not whether the representative possesses a document called a power of attorney.

A real transaction also requires checking execution, scope, effectiveness, revocation, and any applicable recording requirements. Chapter sources

Worked scenario: one property, three relationships

Map each brokerage to its client before analyzing payments or promises; two affiliated salespersons on opposing sides can create one brokerage's dual agency.

Morgan hires Harbor Realty to list a duplex. Harbor salesperson Lee markets it. Buyer Casey signs a buyer representation agreement with Valley Realty and works with salesperson Jordan. Morgan agrees to pay an amount toward Casey's brokerage expense.

Harbor represents Morgan, while Valley represents Casey. The seller's contribution does not turn Valley into Morgan's agent. Lee cannot accept Casey's offer for Morgan merely because Lee is the listing salesperson. Jordan cannot promise that Morgan will make repairs. Each agent must stay within actual authority and communicate accurately about the other party's decisions.

If Casey instead becomes represented by another Harbor salesperson, analyze the brokerage's role again: Harbor would be representing opposing principals in the same transaction. The matter requires the dual agency disclosures and consent discussed in the next lessons. Assigning two staff members does not create two unrelated brokerages.

Exam review

Name the principal, identify the requested act, and locate its source of authority before deciding whether the transaction binds someone.

Identify the principal before classifying the duty. Identify the task before deciding whether authority exists. Agency, compensation, and signing authority are related but separate issues. A client relationship depends on authorization and conduct, not who happens to pay the bill. A salesperson's involvement must always be understood within the responsible brokerage's role.

Change one fact

The same repair order, three authority problems

Owner Avery appoints a manager to administer a small rental building. The written agreement permits routine repairs up to $1,000. The manager orders an elective $7,500 renovation. Assume no emergency, no actual additional approval, and no special writing issue. Change only the facts describing the contractor's knowledge and the owner's conduct.

Known restriction

Changed fact
The contractor received the written $1,000 limit before accepting the renovation order. Only the manager claims that the owner now allows larger projects.
The known restriction defeats reliance on the manager's unsupported claim of greater power.
  • A general management appointment does not remove the spending limit. The contractor has direct contradictory information and cannot establish ordinary care merely by repeating the manager's assurance.
  • The owner might separately ratify the work later, but that is a different source of obligation. Without additional facts, do not infer ratification simply because completed work remains attached to the building.

Owner-created appearance

Changed fact
The owner introduced the manager as authorized to approve renovations of this size and knowingly allowed that practice. The contractor has no notice of the private cap and incurs a materials obligation in good-faith reliance.
Ostensible authority becomes a substantial issue even though the private agreement imposed a lower actual limit.
  • The relevant appearance comes from the owner rather than the manager alone. The contractor's incurred obligation supplies a concrete reliance fact, not merely an unacted-on belief.
  • Civil Code section 2334 also requires good faith and ordinary care. An unusually suspicious transaction or known restriction would change the analysis; the manager's title alone still does not decide it.

Later informed adoption

Changed fact
The contractor knew the limit, but the owner later receives the full proposal and material facts and validly adopts the entire transaction in the required manner.
Analyze ratification rather than trying to reconstruct a reasonable belief the contractor never had.
  • Ratification addresses an initially unauthorized act after the principal learns what occurred. It does not require pretending the manager possessed authority at the outset.
  • Acceptance must satisfy governing formalities and concern a lawful transaction. The owner cannot select only the advantageous portion of an indivisible bargain while rejecting the corresponding payment obligation.

TakeawayKeep actual authority, ostensible authority, and ratification on separate tracks. A changed reliance fact or later adoption can change the result without changing the manager's job description or the amount of the work.

Exam pitfalls

A useful act must be authorized.

Check the agreement and the principal's conduct.

Benefit to the property is not itself delegated power.

The agent's assurance creates ostensible authority.

Look for a manifestation attributable to the principal.

Unsupported self-assertion cannot supply the missing source.

Belief alone establishes protected reliance.

Identify ordinary care, good faith, and value or liability incurred.

Section 2334 requires more than an unacted-on impression.
