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.
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.
Assume the brokerage represents only the seller in this transaction.
- Sellerrepresented client
- The principal receives fiduciary representation under the agency.
- Affiliated salespersonlicensed affiliate
- Performs licensed work through the responsible broker.
- Unrepresented buyernonclient duties
- A third party still receives required honesty and disclosure, not seller-side loyalty.
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
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.
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.
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:
- Did a relationship and corresponding duties arise?
- Does the agent possess authority for the particular act?
- 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.
Engagement evidence: fictional file review
An owner orally asks a broker to find a buyer. The broker agrees, begins negotiations, and later claims an orally promised fee.
- UndertakingFind and negotiate with prospective purchasers.
The agreed undertaking and conduct can establish a relationship carrying duties; an oral arrangement is not permission to act dishonestly.
- Compensation evidenceOnly an oral promise of a brokerage fee.
The statute of frauds separately governs the required writing for an agreement employing a broker to buy or sell real estate for compensation.
- Proposed signatureBroker proposes signing the sale contract for the owner.
Finding a buyer does not itself grant signing authority. Authority for a contract legally required to be written must be given in writing.
Do not answer all three questions with "there is an agency." Identify duties, fee enforceability, and the particular act authorized.
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.
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.
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.
- 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.
- Material informationOwner receives the complete price and service-plan terms.
Informed adoption requires the material transaction facts, not merely knowledge that equipment arrived.
- 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.
- 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.
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.
- 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.
- Express powersCollect rents and order ordinary maintenance at 18 Pine Street.
These management powers identify the acts the owner granted.
- Express restrictionNo power to sell, mortgage, or sign a deed.
Broad wording such as "manage all matters" does not erase this specific limitation.
- 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.
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.
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.
- 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.
- 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.
- 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.

A useful act must be authorized.
Benefit to the property is not itself delegated power.
The agent's assurance creates ostensible authority.
Unsupported self-assertion cannot supply the missing source.
Belief alone establishes protected reliance.
Section 2334 requires more than an unacted-on impression.
