Dealing With Real Estate Agents as a Seller in NSW: The Definitive 2026 Guide

How to select and supervise an agent, avoid unexpected commission, interpret price advice, disclose accurately, manage an auction and leave an agency agreement without an expensive dispute.

Direct answer: When you engage a NSW real estate agent to sell your home, the agent is your representative and owes you contractual, fiduciary and statutory obligations. Those duties do not guarantee a particular sale price, a successful auction or a risk-free transaction. Your strongest protection is a carefully reviewed written agency agreement that defines commission triggers, marketing costs, campaign reporting, authority, exclusivity, termination and post-termination claims. You also remain responsible for the sale contract and accurate vendor information supplied to the market. NSW Government agency agreement guidance; agent rules of conduct.

2026 law-change alert: NSW announced staged agent-law reforms on 29 October 2026. Changes to penalties and disciplinary powers commenced 29 June 2026. New obligations concerning estimates, sale advertisements, agency agreements and record keeping begin 17 November 2026, with a further Statement of Information requirement from 8 February 2027. This article describes the position as at 31 October 2026; recheck the official timetable before publication or relying on a later sale campaign.

The six things a seller should know before signing

1. Commission is negotiable, but the circumstances in which commission is earned matter as much as its percentage.
2. Exclusive agency can outlast your enthusiasm for the agent. Ending a campaign, ending exclusivity and eliminating a later commission claim are not necessarily the same thing.
3. The seller normally controls the reserve and whether to accept an offer. But your agent has disclosure, record-keeping and honest-dealing duties.
4. Price estimates must be reasonable and evidence-based. A high appraisal to win your listing is not proof the market will deliver that price.
5. You remain responsible for vendor contract disclosures and promises you authorize. Your agent is not your conveyancer or planning expert.
6. Use written instructions and reporting. Buyers' feedback, offers, marketing expenditure and negotiations are too important to leave to memory.

1. What legal duties does my agent owe me?

Short answer: A selling agent is your representative and must comply with the Property and Stock Agents Act 2002, the Property and Stock Agents Regulation 2022, their agency agreement and relevant Australian Consumer Law requirements. NSW rules of conduct explicitly recognize fiduciary obligations and duties to act in the client's best interests; agents must also be honest, fair and professional when dealing with other parties. NSW agent rules.

That means an agent should not prioritize a hidden personal benefit over your interests, conceal relevant conflicts, misrepresent feedback or make unauthorized commitments. It does not mean the agent can override your lawful instructions or guarantee a price.

Does an agent have to achieve the price they estimated?

No. A reasonable estimate is a professional assessment, not a price guarantee. The question is whether the estimate was genuinely supportable when made and revised appropriately as evidence changed. Ask for sold comparables, their similarity to your home and a candid assessment of what would cause the result to exceed or fall below the estimate. NSW seller price-estimate guide.

2. What is an agency agreement and what must it contain?

Short answer: The written agency agreement is the contract appointing the agent. It should identify the parties, property, services, fees, commission entitlement, authority and applicable disclosures. NSW requires an agreement meeting statutory requirements; Fair Trading explains that an agent generally is not entitled to commission or expenses without the required written, signed and served agreement. NSW professional guidance.

The seller should receive the relevant prescribed guide before signing; the agent-signed copy must generally be served within 48 hours after the client signs. Assistant agents cannot themselves enter into the agency agreement on behalf of the agency; the appropriate Class 1 or 2 licensee must do so. Professional agency-agreement guidance.

What clauses are most important to negotiate?

Sample question to ask your solicitor: “If I terminate after an unsuccessful auction, then sell privately to someone who attended an open home two months earlier, exactly what commission might still be payable under this wording?”

3. Exclusive versus sole versus open agency: what changes for the seller?

Exclusive: The agent has exclusive selling rights for the applicable term and may be entitled to commission even if you or someone else finds the buyer, depending on the contract. Some clauses preserve a claim for a buyer introduced during the agency period.

Sole: Similar exclusivity, but ordinarily permits you to find a buyer independently without commission to that agent where the buyer was not introduced by the agent, subject to the agreement.

Open/general: Multiple agents may market the property, with commission payable to the one entitled under the applicable arrangement. Disputes can arise about who effectively caused the sale.

Auction: Usually involves an exclusive agency arrangement plus specific auction services, expenses and timing. The actual agreement controls. NSW Government agency types.

Why can two agents seek commission on one property?

Because an exclusive or protected-introduction clause in the first agreement may continue to operate even after you appoint a second agent. The second agent may have its own entitlement. The government explicitly warns sellers to terminate the first appointment properly before engaging another. A notice ending the marketing campaign may not automatically neutralize every post-termination commission clause. Agency agreement guidance.

Should I insist on a list of protected buyers when the agreement ends?

Yes, as a practical negotiating measure. Require a written, dated list identifying people the original agent says they introduced, the relevant contact and the contractual basis for any continuing entitlement. The law does not automatically require the agent to accept your preferred clause, but a well-drafted list and limited tail period can reduce disputes. Your solicitor should adapt the mechanism to the agreement.

4. How much commission must I pay and what happens if settlement fails?

Commission rates are negotiable. There is no single mandatory NSW residential sales commission. Ask every candidate for an all-in GST-inclusive comparison, with commission at your expected price, a lower-price scenario and an upside scenario. Check marketing, auctioneer, staging and administrative expenses separately. NSW seller agency-agreement guide.

Why the commission trigger matters more than a small percentage change

Consider an illustrative sale at $2.5 million. At 1.8% including GST, the commission would be $45,000. At 2.0%, it would be $50,000. But an agreement that makes commission payable on exchange even if completion fails can present a much more consequential risk than that $5,000 difference. Whether commission is payable after a failed settlement depends on the particular agreement and law. The government requires a prominent warning where the contract provides for commission despite non-completion. Agency agreement guidance.

Never assume “no sale, no fee” covers every expense. Contract preparation, advertising, photography and auctioneer expenses may be payable even if no contract exchanges, if agreed and lawfully incurred.

What about tiered commissions or performance incentives?

A higher percentage for a price above a threshold can align incentives but can also reward behavior you did not intend. Calculate the dollar payout at realistic sale prices. You may instead prefer a straight rate and measurable service commitments. Avoid assuming any structure is necessarily best without calculating its effect.

5. What is the agency-agreement cooling-off period?

NSW residential selling agency agreements normally have a one-day cooling-off period that ends at 5 pm on the next eligible business day or Saturday after signing, excluding Sundays and relevant holidays. For example, signing Friday typically means the period ends at 5 pm Saturday. The seller can rescind within that period by the prescribed written process; where properly rescinded, the agent cannot charge relevant commission, costs or damages and must return sums already paid. A waiver has specific advance-document and form requirements. NSW professional guidance.

This is the agency-agreement cooling-off period, not the buyer's contract cooling-off period. They are different legal relationships and timeframes.

Can I cancel after cooling-off?

It depends on the contract and law. Check whether the exclusive period still runs, how written notice must be given, and whether expense or commission obligations survive termination. NSW guidance says to give written notice and review the agreement's notice requirements. For a material dispute, obtain advice before appointing a replacement agent. NSW agency agreement guide.

Does an unsuccessful auction automatically end my agreement?

No. The agreement's expiry, termination and protected-buyer provisions control. An auction result may change the marketing strategy, not the underlying appointment. Ask the agent to state in writing whether exclusivity continues, when it expires, what fees remain outstanding, and how post-auction buyers will be treated.

Seller exit checklist

1. Locate the signed agreement, prescribed guide and any amendments.
2. Identify the exact exclusive period, ending date and any automatic continuation.
3. Find the clauses for written termination, commission on failure to settle and introduced purchasers.
4. Request an itemized marketing expenditure reconciliation.
5. Obtain the agent's written list of claimed protected buyers and any open offers.
6. Give a termination notice complying with the contract, retaining delivery evidence.
7. Have your solicitor check exposure before appointing a second agent.

6. What are agents legally required to tell sellers about offers?

As a general rule, agents must communicate offers to their vendor client, subject to the law and any lawful written instructions limiting what is forwarded. NSW guidance states sellers may direct agents in writing not to pass on offers below a threshold. The agent should nonetheless handle offers honestly; from 17 November 2026, certain offers requiring a revision of the estimated selling price must be reported even if prior instructions would otherwise exclude them. NSW making-an-offer guidance; reform timetable.

Can the seller refuse the highest offer?

Yes, before a binding exchange, the seller generally chooses whether to proceed. Certainty of financing, settlement timing, inclusions and other terms may matter. A seller is not ordinarily obliged to accept the highest monetary offer.

Should I require every offer to be in writing?

You can request a written reporting protocol. Verbal offers can be real, and agents may lawfully communicate them; insisting on documentation for serious negotiations helps record material terms. A practical report contains the price, purchaser identity as appropriate, deposit, finance, conditions, settlement period, status, time received and seller instructions. Don't assume refusal to supply the identity of a prospective buyer automatically proves misconduct.

Can the agent exaggerate or suppress buyer feedback?

No agent may lawfully mislead their client. The September 2026 NSW Fair Trading inspection campaign reported an agent warning for recording purchaser feedback that did not accurately reflect what inspectors said at an open home. That illustrates a seller-specific risk: feedback can influence your decisions about price and whether to accept an offer. NSW enforcement release.

Seller protection: request weekly written reports separating confirmed offers, indicative expressions of interest, genuine feedback, the agent's interpretation and the action recommended.

7. How do the NSW underquoting laws affect sellers?

Underquoting is not just a buyer problem. An inaccurate guide can change the campaign's buyer pool, the seller's expectations and the regulator's scrutiny of the agency. Your agent must provide a reasonable estimated selling price, backed by evidence and revised when required. The agreement records that estimate. NSW Government seller pricing guidance.

At 31 October 2026, a significant reform package has been announced with staged commencements. Starting 17 November 2026, further obligations apply to advertisements, comparable-sales assessments, price revisions, notifying sellers of relevant offers and maintaining certain records; from 8 February 2027 the Statement of Information regime begins. Some penalty increases already commenced on 29 June 2026. See the official changes page, rather than treating every announced rule as already operative.

Should I choose the agent who promises the highest price?

Not without examining evidence. Ask three agents to provide recent nearby comparable sales, differences in land/condition/layout, likely buyer segments, campaign budget, risks and a plausible price range. Ask what evidence would cause them to change the guide. A high estimate is not a seller guarantee.

What does the September 2026 enforcement campaign reveal?

Fair Trading said almost 80 open homes were inspected; 10 agents received fines totaling $20,900 and additional warnings and education directives were issued. A quoted estimate of $3.65 million was inconsistent with the agency's $4 million–$4.4 million recorded appraisal in one reported matter. These results show live enforcement, not the overall proportion of agents breaching the law. NSW Government release.

8. Who sets the reserve and what happens when a property passes in at auction?

The seller sets the reserve with advice from the agent. NSW Government guidance says you must give your agent the reserve in writing before bidding begins. At a conventional auction, a property below reserve may be passed in; the seller can then negotiate or continue marketing. A seller cannot assume the auction date terminates commission or marketing agreements. NSW selling steps.

Is a vendor bid allowed?

A vendor bid is distinguishable from a prohibited dummy bid. NSW auction rules permit a properly disclosed vendor bid within applicable constraints. Fabricated competitive bidding and collusion are prohibited. NSW auction rules.

Should I accept a pre-auction offer?

It is a commercial decision. Ask for an evidence-based estimate of likely competition and price, not just the agent's enthusiasm. Obtain a clear comparison: pre-auction amount, contract conditions, cooling-off arrangements, certainty of funds, expected auction outcome, marketing spent and remaining budget. An agent's advice is input; the seller makes the decision.

9. What must a seller disclose and who is responsible for the contract?

Your solicitor or conveyancer should prepare a compliant contract before marketing starts. In NSW, the sale-contract disclosure rules require prescribed documents and warranties; missing documents can give buyers rescission rights within the applicable time and circumstances. The seller should provide accurate information about title, planning, improvements and any relevant matters known to them. NSW selling steps; Conveyancing (Sale of Land) Regulation 2022.

Do not confuse agent disclosure duties with vendor contract disclosures. The agent must comply with agent legislation and Australian Consumer Law. The vendor has separate sale-contract disclosure obligations and may face contractual or other claims if representations or warranties are inaccurate.

Should I tell my agent about a previous defect, repair, claim or DA issue?

Yes, disclose known material issues accurately to your solicitor and agent. Ask your solicitor what belongs in the contract, what is legally required, what supporting evidence to provide, and how the agent should describe it. Failing to tell the agent does not necessarily eliminate the seller's exposure; it can also make misleading advertising more likely. The law does not require treating every minor historical repair as a statutory “material fact,” but accuracy matters.

What if a pool has a non-compliance certificate?

Subject to the NSW rules and exceptions, it may be permissible to sell with a valid non-compliance certificate in the prescribed contract documents. When the ordinary post-settlement regime applies, the buyer generally assumes the task of rectification and obtaining compliance within 90 days after settlement, unless significant safety-risk provisions apply. Your agent should describe the certificate accurately and your solicitor should ensure the contract documents are correct. NSW pool guidance.

Do I have to guarantee a new home is fully DA compliant?

Not automatically by virtue of selling a home; the applicable statutory warranties, prescribed contract terms, express promises and other laws matter. However, do not authorize absolute marketing statements such as “all consent conditions satisfied” unless you have documentary support. Your solicitor should consider how any genuine unresolved works, partial OC, compliance notices or relevant ongoing conditions are disclosed and allocated.

Can the agent negotiate special conditions with the buyer?

The agent may discuss commercial terms within their authority, but contract amendments should be handled and approved by your conveyancer or solicitor. NSW guidance states agents face restrictions on participating in contract exchange or making the contract where the client has advised or the contract identifies a legal representative, absent appropriate express authorization. NSW sales-contract guidance.

Seller protection: instruct the agent in writing that no compliance warranties, repair obligations, settlement extensions, price adjustments or inclusion changes are to be promised on your behalf without your solicitor's written approval.

10. Three real NSW cases: conflicts and commission after another agent takes over

D Capital 2 Pty Ltd v Western [2022] NSWSC 1064 — undisclosed buyer interest

This NSW Supreme Court dispute involved a block of Terrigal units. The person who had acted as an agent for vendors was also behind a corporate purchaser, and the vendors were not told the relevant interest before exchange. The court found breaches of fiduciary obligations associated with undisclosed conflict and profit, and ordered repayment of commissions in the relevant circumstances. The case also involved complicated option and completion disputes; it is not a holding that every agent's involvement in a purchasing company necessarily invalidates a sale. The seller lesson is to insist on written disclosure of any agent or associate interest in a proposed buyer. NSW judgment; REINSW legal analysis.

Freedom Development Group v D’Ettorre Properties [2023] NSWCA 81 — commission claim rejected

This commercial-property case turned on an agency agreement requiring the agent to have effectively introduced the purchaser. Following negotiations that fell through, another agent negotiated a sale through a different purchasing arrangement. The NSW Court of Appeal found the first agent had not proved the required sufficient causal nexus and dismissed its commission claim. This result does not override broader, differently drafted exclusive-agency terms. It illustrates why the actual words of the commission trigger and the evidence of introduction matter. NSW Supreme Court published case summary.

Prestige Residential Marketing v Depune [2008] NSWCA 179 — commission claim succeeded

In another commercial-property dispute, a seller proceeded with another agent after earlier negotiations. The NSW Court of Appeal concluded that the first agent's activities were an effective cause of the eventual sale under that agreement and awarded $85,800 commission plus interest and costs. The two Court of Appeal cases produce opposite results because the contract wording and facts differ—not because there is a simple universal rule about the first or last agent. NSW Court of Appeal judgment.

What these cases establish: When terminating an agent, check not only the formal expiry date but the actual causal link, buyer identity and contractual test for any later commission. For ordinary residential sellers, negotiate a finite, unambiguous period and documented list of introduced buyers before signing.

11. What if my agent has a conflict of interest or receives a referral benefit?

Agents must disclose conflicts and relevant relationships, and act in the client's best interests. NSW rules address gifts and benefits that present conflicts and relationships with service providers. NSW Government guidance warns that vendor advocates and referrals may have commercial arrangements with agents and that inappropriate commission sharing can be unlawful. Ask plainly who is paid by whom. Rules of conduct; seller referrals guidance.

Potential examples include recommending affiliated styling businesses, receiving advertising incentives, an undisclosed interest in the purchasing entity or prioritizing a referral channel for personal gain. An actual conflict finding requires facts; not every referral or relationship is unlawful.

What should I require in writing?

Ask for disclosure of referral relationships, beneficial interests, rebates, discounts, commissions and incentives linked to marketing suppliers or prospective purchasers. Require a budget comparison where suppliers are recommended. Keep the disclosure with the agency agreement.

12. How should deposits and settlement instructions be handled?

A selling agent may receive the purchaser's deposit under lawful arrangements, often through an agency trust account, with the sale contract and legal representatives specifying the handling and release rules. An expression-of-interest payment is different from a contract deposit and does not itself create a sale. Do not instruct early deposit release or authorize expenses out of trust money without independent legal advice and proper documentation.

Real misconduct example: In March 2026 NSW Fair Trading reported the prosecution of a former agent for misappropriating rental receipts from a property owner's funds. That involved property management, not a residential sale deposit, so it should not be misrepresented as evidence that selling agents commonly mishandle deposits. It does, however, illustrate why agent licensing, trust-account rules and regulatory oversight matter. NSW Fair Trading prosecution report.

13. What protections do I have if my agent performs poorly or breaches duties?

Start by distinguishing dissatisfaction from a provable breach. A disappointing sale price, low inspection numbers or a passed-in auction does not by itself establish misconduct. Written evidence of falsified offers, unauthorized expenditure, undisclosed conflicts, misleading reporting or breach of agreed services is different.

Your options may include making a formal written complaint to the agency/licensee in charge, enforcing contractual rights, seeking advice about termination or fee disputes, and referring potential regulatory breaches to NSW Fair Trading. Depending on jurisdiction and facts, NCAT or a court may be relevant to certain commission or civil disputes. Fair Trading discipline is not automatically compensation. NSW disciplinary guidance; NSW agency agreement guidance.

What evidence should I preserve?

Retain the signed appointment, disclosures, marketing invoices and approvals, price estimates and supporting comparables, all offer logs and campaign reports, inspection numbers, buyer feedback, advertising snapshots, reserve instructions, auction results, communications about termination and any protected-buyer list.

Can I check an agent before hiring?

Verify the licence through the NSW public register, examine available disciplinary records and ask for comparable recent sales and specific client references. Public registers cannot establish that an agent is problem-free; absence of a published action is not a guarantee.

14. Seller timeline: six stages of controlling the process

Email template: setting clear instructions with your agent

We would like the following process for the sales campaign. Please send a written weekly report listing inspection numbers, genuine offers and their conditions, buyer feedback distinguished from your interpretation, marketing expenditure against the approved budget, comparable sales and any recommended change to the estimated selling price. Please obtain our written approval before committing extra marketing expenditure or representing that we will undertake repairs, provide warranties or agree to contract changes. We also require a clear record of all prospective purchasers whom you consider introduced under the agency agreement.

Email template: requesting clarity before terminating

Before we determine our next steps, please confirm the precise expiry date of exclusivity, contractual notice requirements, costs already incurred and any further charges, the commission trigger, whether any entitlement is asserted after termination, and a dated list of purchasers whom you say were introduced by your agency together with the contractual basis for a later commission claim. Our solicitor will review the agreement before we issue any notice or engage another agent.

Frequently asked questions: NSW sellers and real estate agents

Is a selling agent legally required to act in my best interests?

Yes, the NSW rules of conduct recognize fiduciary obligations and the duty to act in the client's best interests, alongside honesty and professional conduct requirements.

Are real estate commission rates fixed by law?

No. Commission and relevant marketing charges are negotiable. Examine total GST-inclusive costs and exactly when they become payable.

Does an agent get commission if my house does not sell?

Not automatically. The agency agreement and applicable law determine commission entitlement; separately authorized advertising or other expenses may still be payable.

Can an agent get commission if the buyer does not settle?

Potentially, if the agreement validly provides for it. NSW requires warning language for agreements containing that risk. Have the clause reviewed.

How long can an exclusive agency agreement last?

The duration is negotiated; NSW guidance states there is no fixed statutory minimum or maximum term for these agreements. Choose an explicit date and avoid ambiguity.

Can I change agents after the auction?

Potentially, but first check if the agreement is still active and whether post-termination commission protection applies.

Can I cancel an agreement one day after signing?

A statutory cooling-off period ordinarily ends at 5 pm on the next eligible business day or Saturday, subject to waiver and applicable rules. Use the prescribed written rescission process.

Can two agents claim commission on the same property?

Yes, competing claims can arise from overlapping agreements or buyer-introduction clauses. Obtain legal advice before reappointing.

Is “exclusive agency” the same as “sole agency”?

No. A sole arrangement ordinarily preserves certain rights to find your own buyer, while an exclusive appointment can entitle the agent even if another person finds the purchaser; read the particular wording.

Can I negotiate the agent's marketing budget?

Yes. Require a budget, clarity about GST and a process for approving extra spend.

Must I accept the highest offer?

Generally no, unless you are already contractually bound or exceptional facts apply. You may weigh conditions and settlement certainty.

Does the agent have to present every offer?

Generally offers are to be communicated subject to lawful written seller instructions; special requirements for certain price-estimate changes begin on 17 November 2026.

Can the agent change the advertised price without my consent?

Price estimates must remain legally compliant, and the agent may have statutory duties to revise them. Separately, ask for a written communication protocol and understand the agreement's authority provisions.

Can my agent make promises about repairs or approvals?

The scope of the agent's authority matters, but the agent should not unilaterally create legally significant commitments outside their authority. Require solicitor approval for contract wording.

Can I sell with an outstanding pool non-compliance certificate?

Often yes, subject to prescribed contract documents, safety rules and exceptions. The certificate should be accurately described, and the buyer's obligations considered.

Do I have to provide a sale contract before advertising?

Yes, NSW requires the contract of sale and prescribed documents to be prepared and available before marketing residential property.

Does my agent have to disclose known material facts to purchasers?

Yes, prescribed material facts known or reasonably knowable must be disclosed, and statements or silence must not mislead. Provide accurate information to your agent and solicitor.

Should I conceal a past defect if it has been fixed?

No. Give your legal adviser the full factual history, including repair reports, so they can advise what must be disclosed and how to describe it accurately.

Is underquoting only a buyer's problem?

No. It can distort your campaign, attract inappropriate enquiries and expose the agent to enforcement. Ask to see the evidence for the estimated selling price.

Is a high agent appraisal a contractual promise?

No. It is an estimate that must meet legal standards, not a price guarantee.

Who decides the reserve at auction?

The seller. NSW guidance requires the seller to give the reserve instruction to the agent in writing before bidding starts.

Does a passed-in auction end the exclusive agreement?

No, not by itself. The agreement's term, termination and commission clauses must be examined.

Can I recover losses if my agent misleads me?

Potentially, depending on legal grounds, evidence, causation and loss. Seek advice on contractual and other remedies; regulatory penalties alone do not compensate you.

Can I see whether the agent has disciplinary history?

You can inspect NSW licensing and available disciplinary registers; their coverage is limited and they are not proof of service quality.

What's the single most important clause to review before appointing an agent?

The commission entitlement and post-termination wording together—especially if the sale fails, the auction passes in, or you switch agents.
