When it comes to selling your property, the type of mandate you sign can make or break your experience—and your profit. Many sellers believe that appointing multiple agents will increase their chances of a quick sale. In reality, an open mandate often works against you, while a well-structured sole and exclusive mandate—with the right protective clauses—ensures your agent is truly working in your best interests.
The Hidden Dangers of an Open Mandate
An open mandate allows you to appoint multiple agencies—or even sell privately—at the same time. On paper, this sounds like maximum exposure. In practice, it creates significant risks:
1. The Double Commission Trap
This is the biggest financial danger. If a buyer is introduced to your property by one agent but concludes the sale through another, both agents can claim commission. Courts have consistently held that the agent who first showed the buyer the property may be deemed the "effective cause" of the sale—even if another agent finalised the deal. You could end up paying commission twice.
2. Weak Marketing and Less Effort
Agents are less willing to invest time and money in professional photography, advertising, and show houses if there's no guarantee they'll be paid. Why spend heavily when another agent could swoop in and secure the commission?
3. Confusion and Reputational Damage
When your property appears across multiple platforms with different photos, descriptions, and even different prices, it looks chaotic and unprofessional. Buyers may assume you're desperate—and that invites lowball offers.
4. Agents Prioritise Speed Over Price
With multiple agents racing against each other, the focus shifts from negotiating the best price to being the first to secure a deal. You'll be pressured to accept the first reasonable offer rather than holding out for a better one.
5. No Accountability
When no single agent is responsible, there's no clear person to hold accountable if things go wrong. You'll manage multiple agents, overlapping viewings, conflicting feedback, and inconsistent communication.
Why a Sole and Exclusive Mandate Is Safer
A sole and exclusive mandate gives one agency the exclusive right to market your property for a specific period. When you choose the right agent, this structure offers clear advantages:
- One point of responsibility—pricing, marketing, feedback, viewings, and negotiation are all managed by a single professional
- Stronger marketing—agents invest more because they know they'll be rewarded for their efforts
- Consistent pricing and messaging—no confusing contradictions across platforms
- Better negotiation—agents can focus on getting the best price, not racing the clock
- No double commission risk—only one agent can claim commission
"A sole & exclusive mandate creates one clear point of responsibility. One agency manages the pricing, marketing, buyer feedback, viewings, negotiation and reporting process."
The Risk of a Weak Sole Mandate
However, a sole mandate is only as good as the agent you choose—and the contract you sign. The main risks include:
- The agent overpromises on price just to win the mandate
- Weak marketing despite exclusivity
- Poor or infrequent feedback
- The mandate period is too long, and you feel locked in
- The agent doesn't adjust strategy when the market gives feedback
The solution? Add a protective annexure to your sole mandate that holds the agent accountable to clear performance standards.
How to Protect Yourself: The Seller's Protective Annexure
Here is a practical annexure you can request to be added to any sole and exclusive mandate. It ensures the agent is legally bound to work in your best interests—and gives you clear grounds to cancel if they don't.
ANNEXURE "A" – SELLER'S PROTECTIVE ADDENDUM
(To be read in conjunction with the Sole and Exclusive Mandate Agreement)
1. PREVAILING CLAUSE
In the event of any conflict, ambiguity, or inconsistency between the provisions of this Annexure and the main Mandate Agreement, the provisions of this Annexure shall prevail and the conflicting terms in the main agreement are hereby deemed deleted and of no force or effect.
2. PERFORMANCE OBLIGATIONS (THE "KPI CLAUSE")
The Agent warrants and undertakes the following minimum marketing and reporting standards:
2.1. Reporting: The Agent shall provide the Seller with a detailed written progress report every 7 (seven) calendar days. This report must include the number of viewings conducted, written feedback from all viewers, and a summary of all marketing activities performed that week.
2.2. Marketing: Within 5 (five) business days of signing, the Agent must complete: professional photography, a virtual tour (if applicable and technologically feasible), and listing on at least three (3) major national property portals widely used in the property's geographic area, as well as on the Agency's own website. A "For Sale" board must be erected at the property unless prohibited by body corporate rules or municipal bylaws.
Additionally, the Agent undertakes that:
2.2.1. The Agent shall respond to all buyer enquiries within 24 (twenty-four) hours, including weekends and public holidays.
2.2.2. The Agent shall notify the Seller in writing of any planned personal holidays to be taken during the sale period and shall inform the Seller of the name and contact details of the person who will take over management of the sale during their absence.
2.2.3. The Agent confirms that they hold a valid personal Fidelity Fund Certificate (FFC). If the Agent is a Candidate Property Practitioner, they shall disclose the name and FFC number of their supervising Mentor below:
Mentor Name: _________________________
Mentor FFC Number: ____________________
2.2.4. The Agent shall send the Seller a copy of all marketing materials (including but not limited to portal listings, social media posts, brochures, and advertisements) immediately upon publication for the Seller to review for accuracy.
2.2.5. The Agent shall not advertise a listing price other than the price agreed to in writing with the Seller. Any change to the listing price shall only be made with the Seller's prior written approval. The Agent shall send the Seller a copy of all updated marketing materials once a new price has been posted.
2.2.6. The Agent shall send the Seller a copy of any and all marketing materials posted publicly within 24 (twenty-four) hours of such publication.
2.3. Consequence of Breach: Failure to comply with clause 2.1 or 2.2 (including any sub-clauses thereof) for a period of 14 (fourteen) consecutive days, without the Seller's prior written consent, shall constitute a material breach. The Seller shall be entitled to cancel this Mandate with immediate effect by giving written notice, and no penalty or early termination fee shall apply.
3. CANCELLATION FOR NON-PERFORMANCE
Notwithstanding anything to the contrary in the main agreement, and in addition to any rights under the Consumer Protection Act:
3.1. If the Agent fails to comply with the marketing requirements set out in Clause 2.2 above, the Seller shall deliver written notice to the Agent specifying the breach.
3.2. The Agent shall have 7 (seven) business days from receipt of such notice to remedy the breach to the Seller's reasonable satisfaction.
3.3. If the Agent fails to remedy the breach within the 7-business-day period, the Seller reserves the right to cancel this Mandate by giving 20 (twenty) business days' written notice of cancellation, effective from the date of delivery of that notice.
3.4. Upon cancellation under this clause, no penalty, early termination fee, or claim for anticipated commission shall be payable by the Seller to the Agent.
4. PROTECTION PERIOD & "INTRODUCTION" DEFINED
To avoid liability for commission after cancellation or expiry:
4.1. The "protection period" (the period after expiry/cancellation during which commission is still owed) is strictly limited to 30 (thirty) calendar days from the date of termination.
4.2. A "Qualifying Introduction" shall only be deemed to have occurred if:
- The Agent provides the Seller with the prospective purchaser's full name, in writing, prior to or at the time of the viewing; AND
- The Agent physically accompanies that specific prospective purchaser to a physical viewing of the property.
4.3. The mere sending of a digital brochure, email, or social media post shall not constitute a Qualifying Introduction.
5. EXCLUSION OF LIABILITY
The Seller shall not be liable for any commission to the Agent if the property is sold after termination to a buyer who was introduced to the Seller by any other person, including the Seller's own efforts, during the protection period, unless that buyer strictly meets the definition of a "Qualifying Introduction" as defined in Clause 4.2 above.

Practical Tips for Sellers
Before You Sign:
- Interview multiple agents—don't just choose the highest valuation. The highest price isn't always the best advice; sometimes it's simply what the agent thinks you want to hear.
- Ask for a copy of the agent's Fidelity Fund Certificate and confirm they're registered with the Property Practitioners Board.
- Check the agent's track record—local experience, client reviews, and online presence matter.
- Ensure the mandate has a clear expiry date and states the commission structure upfront.
If an Agent Refuses the Annexure:
If an agency pushes back on your annexure, you can say: "These are standard protections that simply hold you to the marketing promises you already make verbally. If you're planning to do what you say, this doesn't change anything—it just puts it in writing."
If they still refuse, consider it a red flag—they may never have intended to work that hard for you.
Understand Your Rights Under the CPA:
Under the Consumer Protection Act, unless both seller and agent are juristic persons, you generally have the right to cancel a mandate by giving 20 business days' written notice to the agent. If the mandate was signed due to direct marketing (e.g., an unsolicited phone call), you have a 5-day cooling-off period to cancel without penalty.
However, a reasonable cancellation fee may apply to cover the agent's marketing costs. Your annexure avoids this by linking cancellation to non-performance, not just a change of heart.
Final Thoughts
An open mandate may seem like a shortcut to a quick sale, but the risks—double commission, weak marketing, confusion, and lowball offers—far outweigh any perceived benefits.
A well-structured sole mandate with a reputable agent and a protective annexure gives you the best of both worlds: dedicated service, strong marketing, and the legal teeth to hold your agent accountable. Don't leave your biggest asset to chance—protect yourself in writing.
