11.2 Agency, Fiduciary Duties & Dual Agency
Key Takeaways
- The auctioneer or auction firm is the seller's agent under the 15-10 written auction contract; buyers are customers of the sale unless a disclosed dual-agency relationship is authorized.
- The fiduciary cluster is loyalty (highest reasonably obtainable price consistent with lawful instructions), obedience to lawful instructions only, disclosure, accounting (settlement and trust), and confidentiality (reserve and motivation).
- Obedience does not extend to illegal shill instructions; following an undisclosed seller-bid order is 810 ILCS 5/2-328(4) plus 20-15(22), not 'just following the client.'
- Authority is express (the contract), implied (customary increments, clerking, announcing terms), and apparent (the principal's holding-out). Crying items not in the contract exceeds the grant.
- Dual agency or bidding for self requires full disclosure and authorization before the auction; personal interest in a lot must be disclosed then. Confidentiality of seller information continues after the sale.
The auctioneer is the seller's agent
Illinois auction practice is a principal-agent relationship. The seller (consignor, owner, estate representative) is the principal. The auctioneer or auction firm is the agent, hired under the written auction contract that 225 ILCS 407/15-10 requires before the auction date. The license to cry bids does not make the auctioneer a neutral referee. It makes the auctioneer a fiduciary of the seller, with parallel duties to the public under 15-5 and 20-15.
Buyers are customers of the sale, not automatic clients. An auctioneer who also agrees to bid or buy for a bidder, or who has a personal stake in a lot, has left single-agency and entered dual agency / self-dealing. That is lawful only with full disclosure and authorization. Without it, the same facts are 20-15(22) (dishonorable, unethical, or unprofessional conduct of a character likely to deceive, defraud, or harm the public) and, when the auctioneer or seller is bidding without reserved liberty, 810 ILCS 5/2-328(4).
Unlicensed clerks, cashiers, and ring assistants under Rule 1440.240 do not become the seller's agent by holding a paddle or a clipboard. Section 15-15 and Rule 1440.220 still charge the firm and managing auctioneer for what those people do (Chapter 6). The fiduciary sits on the license, not on the temp badge.
The fiduciary cluster
| Duty | Content | Exam failure mode |
|---|---|---|
| Loyalty | Seek the highest reasonably obtainable price consistent with lawful seller instructions and advertised terms | Protecting a friend-bidder, suppressing bids, or steering a lot to the auctioneer's own silent bid |
| Obedience | Follow lawful instructions in the 15-10 contract and any lawful reserve | Following an illegal shill instruction, or ignoring a lawful with-reserve floor |
| Disclosure | Material facts, conflicts, seller-disclosed liens, personal interest in a lot | Silent self-dealing; advertising absolute while hiding a reserve |
| Accounting | Trust handling, settlement, remittance on written demand | Commingling and 20-15(13)–(16) special-account failures (Chapter 8) |
| Confidentiality | Reserve amount, seller motivation, financial distress, unpublished bids | Telling the crowd 'the seller has to sell this week' to gin up bids |
Loyalty is not 'whatever the seller whispers.' It is the highest reasonably obtainable price inside the law. An auctioneer who buries a known material defect to juice the hammer has not been loyal; 15-5 independently forbids misrepresenting a fact material to a purchaser's decision and materially misrepresenting qualities. Loyalty to the seller does not include defrauding bidders.
Obedience is to lawful instructions only. If the seller says, 'Put my brother in the second row and take his bids whenever it stalls, but don't announce seller bidding,' the instruction is an undisclosed 2-328(4) shill. The lawful response is refuse. Following it is not 'just doing what the client wanted.' It is a UCC violation plus 20-15(22). If the seller lawfully reserves a minimum at a with-reserve sale, obedience means not knocking the lot down below that reserve unless the seller modifies the instruction. Advertising the same lot as absolute while holding a secret reserve is not a lawful instruction — it is 1440.260 plus 15-5(1).
Disclosure includes conflicts. A personal interest in a lot — the auctioneer wants the grandfather clock for the house, a spouse is bidding, the firm has a lien to be paid from proceeds — must be disclosed before the auction, not after the clerk writes the ticket. Dual agency (representing seller and a buyer on the same lot) requires full disclosure and authorization from both. A silent 'I'll bid for you against my own consignor' is the exam's dual-agency pattern.
Accounting is Chapter 8 in fiduciary clothing: next-business-day deposit, no commingling, deal-file settlement, remittance within 30 days of a written owner request (20-15(14)). The agency duty and the special-account rules are the same dollars.
Confidentiality covers the reserve, why the seller is selling, and unpublished bids. It continues after the sale. A buyer who asks, two weeks later, 'What was the reserve, and was the estate desperate?' does not get a post-game briefing. Confidentiality is not a license to hide material product defects from bidders; 15-5 still requires honesty about the goods.
Authority: express, implied, apparent — and the edge of the contract
| Kind | Source | Typical auction content | Limit |
|---|---|---|---|
| Express | 15-10 writing and lawful seller instructions | What lots, reserve vs absolute, fee, buyer premium, advertising | Selling a trailer that is not on the contract exceeds express authority |
| Implied | Customary acts reasonably necessary to carry out the express grant | Bid increments, clerking, announcing terms, recognizing ringmen | Implied authority cannot legalize a shill or an unadvertised change from absolute to reserve |
| Apparent | Principal's conduct that leads a third party reasonably to believe the actor had authority | Seller standing by while an office manager announces terms | Apparent authority is the principal's holding-out, not the agent's boast |
Express authority is the written auction contract plus lawful oral instructions that do not contradict it. Implied authority covers the customary machinery of crying a sale: increments, the order of lots, recognizing a ringman's convey, pausing for the clerk. Apparent authority is dangerous because it is created by the seller's (or firm's) conduct. If the consignor stands in the ring and lets an unlicensed assistant accept bids, a bidder may argue the principal held that person out as authorized — while Rule 1440.240 still says only the auctioneer accepts. The license-rule violation and the private-law authority argument can both be true. The exam answer is still: the ringman conveys; the auctioneer accepts.
Scope. Lots, vehicles, or after-thought boxes that are not in the 15-10 contract are outside authority until the writing is amended. Crying them 'because they were on the trailer' is extra-contractual. If they sell, settlement, title, and fee disputes follow. Get the amendment before the bid call.
Dual agency, self-bidding, and the duty that survives the hammer
Work three patterns.
Self-bidding. The auctioneer wants Lot 19, a restored Allis tractor, for a personal collection. Disclose the personal interest before the auction and obtain the seller's authorization, or do not bid. Silent bidding against the crowd is self-dealing. If the bid is on the auctioneer's own behalf without reserved liberty and without disclosure, 2-328(4) gives the competing buyer the avoid-or-last-good-faith choice, and 20-15(22) is in play.
Bidding for a buyer. A regular customer texts, 'Buy me the gun cabinet; you know what I'll pay.' The auctioneer is already the seller's agent. Taking that order without disclosing dual agency to both sides and obtaining authorization is dual agency by stealth. Even with authorization, the auctioneer cannot prefer the customer over a higher independent bid. Loyalty still means the highest reasonably obtainable lawful price for the seller.
After-sale confidentiality. Settlement is done, the check has cleared, and a neighboring dealer asks what the reserve was and whether the seller will have another consignment next month because 'they needed cash.' Reserve and motivation remain confidential. Referring the dealer to the seller is fine. Reciting the reserve is not.
Checklist before you bid or buy against your own sale:
- Disclose the personal interest or dual role before bidding starts
- Obtain the seller's (and, if representing a buyer, the buyer's) authorization
- Do not use unpublished reserve or motivation information to win the lot
- Never run a seller or house paddle without notice that liberty is reserved, and never at an absolute sale
- If the instruction is 'protect with undisclosed bids,' refuse
The auctioneer's duty of loyalty to the seller is best stated as:
A seller at a with-reserve farm sale says, 'If it stalls, take bids from my cousin in the back row, but do not announce that we are bidding.' The auctioneer's lawful response is:
An auctioneer wants to buy a consigned grandfather clock for a personal collection. Before bidding, the auctioneer must:
The 15-10 contract lists a tractor and a baler. At the sale the seller's son waves the auctioneer over to a livestock trailer that is not in the writing. Crying the trailer without an amended authorization is:
