Quick Summary

This case explains a simple rule: estate agents can work for many sellers at the same time. They must keep each client’s secrets. They do not have to share one client’s confidential information with another client, even if the information could affect price talks.

Issues

  1. Must an estate agent tell a seller information learned while acting for another seller?
  2. How do we balance disclosure duties with confidentiality duties?
  3. Can an agent act for competing principals who want to sell similar properties?

Rules

  • Implied Term: Estate agents may act for many competing principals in the same market.
  • Confidentiality: Information from one principal stays confidential; the agent need not reveal it to another principal.
  • Conflict Control: The law accepts this limited conflict so agents can do their job; disclosure cannot defeat confidentiality owed to others.

Facts (Timeline)

Timeline graphic for Kelly v. Cooper facts
  • Agency Created: Seller (plaintiff) hired the agents to sell his house for a commission; target price was about $3.5 million.
  • Second Instruction: The same agents were also hired to sell the next-door house.
  • Common Buyer: One buyer viewed both houses; bought the neighbouring house for about $2 million.
  • Offer on Plaintiff’s House: The same buyer offered $2.5 million; after talks with the seller, the agents completed the sale.
  • Dispute: Seller later learned about the neighbouring sale and said the agents should have told him, as it might affect price talks. He refused to pay commission; both sides sued.

Arguments

Appellant / Agents

  • They could act for both sellers under an implied term.
  • Neighbour’s sale details were confidential; no duty to share with the plaintiff.
  • No proof that the buyer had a “special interest” in buying both, affecting price.

Respondent / Seller

  • Said the info was material to negotiation on his property.
  • Claimed conflict of interest and breach of fiduciary duty.
  • Withheld commission due to alleged non-disclosure.

Judgment

The Privy Council held that the agents were not in breach. Estate agency work assumes multiple principals. A term is implied that the agent may act for competing sellers and must keep each client’s information confidential.

Even if the info about the neighbour’s sale could be “material,” the agents could not disclose it because it was confidential to the other principal. There was no proof that a special interest to buy both properties existed that would change the outcome.

Ratio Decidendi

Implied freedom + strict confidentiality: An estate agent may represent multiple competing sellers. Confidential information from one cannot be disclosed to another. Disclosure duties stop where confidentiality begins.

Why It Matters

  • Sets a clean rule for property markets with many sellers and shared agents.
  • Shows how courts balance materiality with confidentiality.
  • Guides drafting of agency contracts and disclosure clauses.

Key Takeaways

  • Agent can act for competing sellers—this is implied by law.
  • Client secrets stay secret, even if another client would find them useful.
  • Alleged “material info” cannot override confidentiality duties.
  • Prove special interest or concrete impact to claim breach—mere suspicion is not enough.

Mnemonic + 3-Step Hook

Mnemonic: “COMPETE—KEEP—CONFIDE” — Agents may compete for many sellers, must keep secrets, and cannot confide one client’s info to another.

  1. Ask: Is the info confidential to another client?
  2. Check: Does implied term allow multiple principals?
  3. Decide: If yes + confidential → no disclosure duty.

IRAC Outline

Issue

Must an agent disclose information learned while acting for another principal?

Rule

Implied term: agents may act for competing principals and must keep each client’s information confidential.

Application

Neighbour’s sale details were confidential; sharing them would breach duty owed to that seller.

Conclusion

No breach by the agents; commission claim stands, counterclaim fails.

Glossary

Principal
The client who hires the agent to act on their behalf.
Confidential Information
Information received in trust that must not be disclosed without consent.
Implied Term
A term the law reads into a contract to make it work in practice.

FAQs

Agents can act for multiple sellers and keep each client’s information confidential. No duty to disclose one client’s secrets to another.

No. If the info is confidential to another principal, the agent must keep it secret.

That could change negotiations, but in this case such a special interest was not proved.

Set clear terms, ask for market data that is not confidential, and agree on communication steps for offers and counteroffers.
