Case Study: How a Conjunction Deal Between Two Brisbane Agencies Ended in Court
Two Brisbane agencies. One parcel of land. A written conjunction agreement. And then, without warning, the listing agent sells to a different buyer entirely — one never mentioned in the deal — and pockets the full commission without a word to the co-agent who had been working the opportunity for months.
That scenario is not a hypothetical. The District Court of Queensland was asked to resolve exactly that dispute in Equity 2 Pty Ltd v Best Price Real Estate Pty Ltd [2020] QDC 180. The outcome blindsided many practitioners who assumed that doing the work was enough. It wasn’t. The written terms of the agreement were everything, and where those terms ran out, so did the co-agent’s entitlement.
This case study reconstructs the dispute, examines the legal reasoning, and draws out the practical consequences for every Queensland agent who works a conjunction or plans to.
The Setup: Two Agencies, One Opportunity
Conjunction agreements arise in real estate sales involving two agents: Agent A is under an obligation to sell a property in accordance with the terms of their agency, and when they transfer their right to sell to Agent B, a conjunction agreement is created. In commercial practice, this structure is common enough — a listing agent holds the vendor relationship and the Form 6 appointment, while a co-joined agent brings buyer interest, market reach, or specialist access to a particular buyer pool.
In the Best Price Real Estate matter, the two companies — referred to here as the Listing Agency and the Co-Agent, consistent with the anonymised framing used in commentary on this case — had formalised their arrangement in writing. The dispute arose from a conjunction agreement between the two parties, with the agreement relating to the co-agent’s entitlement to commission on the sale of a parcel of land.
The agreement was unambiguous on its face. The agreement was clear: the property was to be sold to a particular buyer by a certain date. That level of specificity — naming the buyer and setting a deadline — is common in conjunction arrangements involving commercial land or off-market residential deals where the co-agent has identified a specific purchaser and the listing agent is aware of who that buyer is. The commission split had been agreed. Both agencies had signed. The deal appeared straightforward.
What happened next was not.
The Dispute: A Different Buyer, A Different Contract
The sale the co-agent had been working toward did not proceed. Whether negotiations broke down, timing ran out, or the buyer’s circumstances changed is not central to the reported decision. What matters is what the Listing Agency did next: the property was sold to a different entity than that specified in the agreement, and the co-agent did not facilitate the acquisition of the alternative buyer.
The Listing Agency settled the contract with a buyer that had no connection to the co-agent’s efforts. It did not inform the co-agent before signing. It did not attempt to vary the conjunction agreement to cover the new transaction. It simply executed a separate sale.
When the property was sold to a different buyer, this was treated as being under a separate contract, and therefore the co-agent was not entitled to a percentage of the commission under the conjunction agreement. The Listing Agency took the position that its obligation under the conjunction agreement was spent — the agreed-upon buyer had not purchased the property, so the payment trigger had not been reached.
The co-agent disagreed. It had spent time, resources, and commercial capital working the deal. The land had sold. Commission had been paid — just not to them. It pursued the claim in the District Court of Queensland.
The Legal Arguments: What the Co-Agent Tried to Establish
The co-agent argued entitlement to a percentage of the commission on multiple grounds: the implied terms of the contract meant that the listing agency was entitled to the commission notwithstanding the fact that the property was sold to a different buyer; the listing agent acted in breach of their implied duty to cooperate with the terms of the contract; and the listing agent was under a duty of good faith which required performance of the contract by way of paying the commission.
These were not trivial arguments. Each one is grounded in recognised Australian contract law principles, and each has succeeded in analogous contexts. The implied terms argument draws on the longstanding principle that courts will imply terms necessary to give business efficacy to a contract. The duty to cooperate argument acknowledges that parties to a contract cannot actively prevent each other from fulfilling their obligations. The good faith argument is more contested in Australian law but has found traction in particular contexts, including in Queensland commercial disputes.
The co-agent’s position, at its core, was that the Listing Agency had deliberately sold to a new buyer in order to avoid paying commission under the conjunction agreement — and that this constituted a breach of obligations that went beyond the express words of the document.
The Court’s Reasoning: Express Terms Only
In a lengthy hearing before the District Court, the judgment followed that it was not just and equitable to recognise implied terms in the contract. In doing so, it would ‘disproportionately benefit the respondent and burden the applicant’.
This is a significant finding. The Court was not saying the co-agent’s commercial grievance was invented. It was saying that the written agreement simply did not support the relief sought, and that importing unwritten obligations into that agreement — even in the name of fairness — would tilt the balance in a way the contract itself did not contemplate.
The Court denied the co-agent’s argument that the listing agency had a duty to cooperate. This was because performance of the conjunction agreement relied solely on the listing agency fulfilling its promise. Therefore, mutual performance was not required, meaning that the duty to cooperate did not apply. The duty to cooperate operates where both parties must perform for the contract to succeed. Here, the co-agent’s obligation was to produce the specified buyer. It had not done so. The listing agency’s obligation under the conjunction agreement only arose if that buyer purchased the property. It had not. There was nothing for either party to cooperate in.
In relation to the co-agent’s argument on the grounds of good faith, the Court held that the listing agency acted reasonably and did nothing which would constitute a contravention of the duty to act in good faith. This was because the sale was not made with the intention to deprive the co-agent of their commission. This is a crucial nuance: the Court did not find that the listing agency had acted with bad purpose. The sale to a different buyer may have been entirely commercial — a better offer, a more certain purchaser, vendor pressure to transact. The absence of any finding of deliberate circumvention meant the good faith argument could not carry the co-agent’s claim across the line.
The Court did note that in the event there was ambiguity surrounding the prospective purchaser, the conjunction agreement may have been recognised before the Court, which would have given rise to the co-agent’s entitlement to commission. That observation is the hinge point of the entire case, and it should be printed out and pinned above every agent’s desk before they sign a conjunction.
The Outcome and Its Consequences
The Court held that where a buyer who was not specified in the terms of the contract purchases the land, the entitlement to commission will not be recognised. The co-agent received nothing.
The decision in Best Price Real Estate shows the reluctance of courts to read outside the terms of an agreement. This is not a new principle. Australian courts have consistently treated agency commission as an all-or-nothing entitlement, contingent on the precise satisfaction of whatever conditions the parties have written into their agreement. As observed in the High Court in L J Hooker Ltd v W J Adams Estates Pty Ltd (1976) 138 CLR 52, the law has made earning commission an all-or-nothing affair — denying agents any reward despite substantial efforts where the precise contractual condition for commission has not been met.
The co-agent lost the case. More than that, it lost the costs of litigating it. Commission disputes in the District Court are not inexpensive proceedings. Two parties who had once cooperated professionally were now adversaries with legal fees and damaged reputations. A parcel of land had sold. Commission had been paid. None of it reached the agency that had worked the buyer side of the deal.
Why This Happens: The Structural Vulnerabilities of Conjunction Arrangements
The Best Price Real Estate case is not an outlier. Real estate commission disputes are not uncommon in Queensland, particularly when multiple agents are involved in a sale. These disputes often arise due to the structure of commission agreements, the effectiveness of agents in securing sales, and compliance with legal requirements.
Conjunction agreements exist in a structural gap. A conjunction agreement allows a real estate agent to transfer their obligation to sell a property to another agent. The agreement is drawn up between two parties: the Listing Agent and the Co-Joined Agent. The critical point is that this agreement governs only the relationship between those two agencies — it is not the vendor’s contract, and the vendor’s Form 6 appointment with the listing agency remains a separate instrument entirely.
Under the Property Occupations Act 2014 (Qld), the listing agent’s authority to act flows from a valid written appointment — the Form 6. The Form 6 will not be valid unless it meets the requirements set out in section 104 of the Property Occupations Act 2014 (Qld), and certain other requirements also apply. The conjunction agreement, by contrast, is a private contractual arrangement between two licensees. If due to a misunderstanding a conjunction agreement leads to a court case, the court will only be liable to enforce what is written in that contract. Anything besides or beyond that scope is open to interpretation, so “implied” knowledge is not acceptable.
This creates the gap that swallowed the co-agent in Best Price Real Estate. The agreement was written tightly around a specific buyer. When that buyer did not proceed, the contract had done its job — it just hadn’t generated any payment. The co-agent’s reasonable expectation that effort would be rewarded found no home in the written document.
Things that were “obvious” will not be legally binding to either party, as they are based on assumption rather than clarity. Courts enforce what parties write. They are not in the business of compensating one party for the other’s failure to draft a document that captured what both of them thought they were agreeing to.
What This Means for Queensland Agents
The specificity of the buyer clause determines your exposure. The most direct lesson from Best Price Real Estate is that naming a specific buyer in a conjunction agreement without also addressing what happens if that buyer does not proceed creates a gap wide enough for the entire commission to fall through. Any conjunction agreement should address the trigger conditions with sufficient breadth to survive a scenario where negotiations with the identified buyer collapse.
Ambiguity, paradoxically, would have helped. The Court explicitly noted that had the agreement been less specific about the purchaser’s identity, the co-agent’s claim may have succeeded. An agreement drafted to cover “the prospective purchaser identified by the co-agent, or any substituted buyer introduced through the co-agent’s efforts” covers the scenario that actually occurred. An agreement that names a single entity does not.
Implied terms, good faith, and duty to cooperate are rarely sufficient to rescue a poorly drafted conjunction. The decision in Best Price Real Estate shows the reluctance of courts to read outside the terms of an agreement. It is important when entering a contract to understand the nature of the terms. As in this case, anything which is not expressly stipulated will not be recognised solely on the grounds of good faith. This applies to any commission claim in Queensland, but it carries particular force in agent-to-agent arrangements where both parties are licensed professionals who understood, or should have understood, what they were signing.
The commission split mechanism needs a payment trigger that survives buyer substitution. The main section of the conjunction agreement should outline the selling price of the property, the agent’s selling fee, and commission percentages that are mutually agreed upon. Beyond those basics, the payment trigger — the condition that activates the co-agent’s entitlement — must be drafted to cover not just the named buyer but any buyer whose engagement flowed from the co-agent’s work. If the listing agency then sells to a related entity, a nominee, or a differently structured purchaser whose interest the co-agent generated, the commission should still attach.
Document your contribution throughout the process. Separate to the written agreement, agents should maintain contemporaneous records of all buyer interactions — communications, property inspections, offers presented, and negotiations conducted. Keeping detailed records of all communications and involvement with buyers and remaining active in the negotiation stage is essential. These records do not substitute for a well-drafted conjunction, but they become critical evidence if the question of the co-agent’s role in generating the eventual buyer is ever contested.
Consider what happens when the deal changes shape. Commercial land transactions, in particular, frequently involve complex ownership structures. A buyer identified as an individual may ultimately purchase through a company, a trust, or a special purpose vehicle. If the conjunction agreement names only “John Smith” as the buyer, and the property settles with “Smith Holdings Pty Ltd as trustee for the Smith Family Trust,” you face the same problem that confronted the co-agent in Best Price Real Estate. Draft the agreement to cover the buyer’s nominees, related entities, and any substituted purchaser whose interest was generated by the co-agent’s efforts.
Get it in writing before introducing the buyer. Use a conjunction agreement any time two parties are collaborating on the same opportunity and want clarity around commission or referral fees. The time to agree on terms is before the buyer is introduced to the listing agent, not after. Once the listing agent has direct contact with the buyer, the co-agent’s leverage — and often the practical need for the listing agent to maintain the arrangement — diminishes.
The Property Occupations Act 2014 (Qld) governs the framework within which agents operate, but the Act’s provisions under subdivision 2 on recovery of reward or expense confirm that commission may be claimed only for actual amounts and that a restriction on recovery applies where there is no proper authorisation. A conjunction agreement that is silent on the scenario that actually occurs provides no proper authorisation for the co-agent to receive anything.
The Best Price Real Estate case study is not a story of bad faith. It is a story of a contract that worked exactly as written, in a way that left one party with nothing. The Queensland market — increasingly active in the Brisbane middle ring, in southeast Queensland’s growth corridors, and in conjunction-heavy off-market commercial segments — generates conjunction deals regularly. The agents who protect their commission are the ones who treat the written agreement with the same rigour they bring to the Form 6.
