Sole mandate vs open mandate: what sellers need to know

Two agency contracts sit on your kitchen table. One agent has visited twice, measured every room, and brought printed comparables. The other has emailed a standard form. Both documents look official, both ask for your signature, and they commit you to opposite arrangements. The agent who wants the signed copy is waiting outside, and nothing on either page tells you which choice serves you better.

What is a sole mandate?

A sole mandate is a written agreement between a seller and a single registered estate agent or agency, granting that agent the exclusive right to market and sell the property for a set period. Only that agent may present buyers during the mandate period. If the property sells during that time, the sole mandate agent earns the commission, regardless of whether they personally found the buyer. An open mandate, by contrast, allows the seller to appoint multiple agencies at the same time. The agency introducing the successful buyer earns the commission. Under an open mandate, the seller may also sell privately without owing commission to anyone.

Both types of mandate are governed by the Property Practitioners Act 22 of 2019, which replaced the Estate Agency Affairs Act and sets out the requirements for valid mandate agreements in South Africa.

Key takeaways

• A sole mandate gives one agent exclusive marketing rights for a fixed period, typically 90 days.
• An open mandate lets you work with multiple agencies at the same time, with commission going to the agent who brings the buyer.
• Under a sole mandate, you may owe commission even if you sell privately during the mandate period, depending on what the agreement says.
• A sole mandate agent has a stronger financial reason to invest in marketing your property, because their commission is protected.
• Open mandates can produce competing agents who undercut each other on price to close the deal quickly.
• Read every clause before you sign either type of agreement.

How a sole mandate works in practice

Under a sole mandate, one agency carries the full marketing responsibility for your property. They pay for the listing, the photography, the portal placements, and any print or digital advertising. They do this because their commission is secured. No competing agent can swoop in after months of their work and close the deal instead.

The mandate period is usually 90 days, though some agreements run shorter or longer. At expiry, some mandates contain a renewal clause extending the agreement automatically unless you give written notice of cancellation. This clause is worth reading twice. A seller in Boksburg once discovered her sole mandate had rolled over for a second 90-day term because she missed a cancellation notice deadline by four days. The original agent had done very little in months two and three, and she had no recourse while the extension ran.

The mandate must state the asking price, the commission percentage, the start and end dates, and what happens if you find your own buyer during the period. If that last clause is absent or unclear, ask for it in writing before you sign.

How an open mandate works in practice

An open mandate allows any registered agency to market your property. You sign no exclusive agreement. The agency successfully introducing the buyer earns the commission. In theory, more agents means more reach. In practice, the outcome is often different.

Agents working under an open mandate know their chances of earning commission are lower, because six other agencies may be showing the same property that weekend. That reduces the financial case for investing in professional photography, premium portal listings, or sustained follow-up. A property sitting on an open mandate for months often attracts offers shopped to the lowest number, because an agent under pressure to close something is more likely to bring low offers to the table.

An open mandate also puts you in the middle of commission disputes. If two agents claim they introduced the same buyer, you can find yourself caught between competing claims neither of which you caused.

Where sole mandates earn their authority

The strongest argument for a sole mandate is what it produces from the agent. When commission is guaranteed to one party, that party has a concrete reason to spend money and time on your sale. In Germiston and Benoni, where comparable properties compete on the same portals within the same week, the difference between a professional listing and a basic one is visible in the number of serious enquiries. A sole mandate agent carrying full risk of no sale has more reason to price correctly, prepare the property well, and qualify buyers before bringing them through the door.

A sole mandate also simplifies your life as a seller. One point of contact, one line of communication, and one person accountable for the outcome means you are not fielding four conflicting weekend reports from four different agents, each describing the same buyers differently.

Where open mandates appear to have the advantage

An open mandate is often described as giving sellers more exposure. More agencies means more buyers. The logic is understandable. Exposure without focus, however, produces noise rather than qualified enquiries.

The open mandate's genuine advantage appears when you have reason to doubt any single agent's network or reach. If the property is unusual, or the target buyer is specific (say, a commercial-residential conversion in a transitional suburb), spreading the net more widely can connect the property to a buyer one agency may not have reached. This is a real, if narrow, benefit. For most residential sales of houses and sectional title units in a competitive suburb, the benefit is largely theoretical.

There is also the commission question. Under an open mandate, if you find your own buyer privately, you owe no commission at all. For a seller who already has a motivated buyer in their network, an open mandate preserves that option. A sole mandate may restrict it.

What the mandate agreement must contain

South African law requires a mandate agreement to include specific details before it is valid. Under the Property Practitioners Act, a written mandate must set out the property address and description, the asking price, the agreed commission percentage and who pays it, the duration of the mandate, and the agent's PPRA registration details. An agent who cannot produce a valid PPRA registration should not be handed a mandate of any kind.

If an agent presents a mandate without a fixed end date, or with an automatic renewal clause buried in smaller print, ask for both to be addressed before you sign. The mandate is a contract. Its terms bind you for the period stated, and in some cases well beyond it if a commission protection clause applies after expiry.

The parent article on property mandate agreements covers these requirements in more detail, including what triggers a commission obligation and how mandate disputes are handled.

Choosing between sole and open: the practical test

Before you sign anything, ask yourself three questions. First: how well does this agent know the area, the comparable sales, and the buyer profile? An agent who can answer with specific numbers earns trust. One who cannot has probably not done the preparation.

Second: what is this agent committing to spend on marketing? A sole mandate agent who cannot name the portals, the photographer, and a follow-up schedule is carrying the exclusivity without the corresponding investment.

Third: what does the agreement say about private sales and post-expiry commission? If you sell privately during a sole mandate period, some agreements require you to pay commission regardless. Others exempt private sales. The clause exists in the document. Read it.

A 90-day sole mandate with a strong agent in a well-supported market is often the faster, cleaner route to a completed sale. An open mandate with multiple average agents in the same market often produces months of activity appearing busy while going nowhere.

Closing Reflection

You came to this question because you want to sign something useful, not something you will regret in month two. The mandate type is not a formality. It shapes how much your agent invests in the sale, what you owe if the deal closes, and how much control you keep over the process. A sole mandate handed to an agent who has done the work earns its exclusivity. An open mandate covering for a lack of certainty about any one agent is a reasonable position, but it carries costs the term does not advertise. Read what is in front of you before the pen touches paper.

Frequently asked questions

Can I cancel a sole mandate early if the agent isn't performing?

Cancelling a sole mandate before its expiry date is not straightforward. The agreement is a contract, and the agent has the right to continue marketing for the agreed period. Most sole mandate agreements do not include a no-fault early exit clause, though some agencies will include one on request. If the agent is in material breach of the agreement, such as failing to market the property at all or acting against your interests, you may have grounds to cancel with written notice. The safest approach is to address performance expectations before you sign, not after you have lost confidence. Ask the agent what they commit to doing in the first 30 days, get it in writing as part of the mandate or in a supporting letter, and set a review meeting at the 30-day mark. If the activity level falls well short of what was agreed, you have a stronger position from which to negotiate an early release. South African sellers who document the shortfall in writing, rather than raising it verbally, tend to reach a quicker resolution when approaching the agency principal.

What happens if I find my own buyer while under a sole mandate?

Whether you owe commission on a private sale depends entirely on what your sole mandate agreement says. Some agreements state the agent earns commission on any sale occurring during the mandate period, including private sales. Others carve out a specific exemption for buyers you introduce independently without any involvement from the agent. You cannot assume either position applies without reading your specific agreement. If you have a buyer in mind before you sign, raise it with the agent before committing to the mandate. Some agents will name specific individuals as excluded buyers in the mandate document. This is a reasonable request, and a good agent will accommodate it rather than insist on a position earning them commission they did nothing to produce. The Property Practitioners Act does not automatically exempt private buyers, so the contractual wording in your specific document determines your liability.

Does a sole mandate mean the agent can accept an offer without my approval?

No. The sole mandate grants the agent the exclusive right to market and present buyers, not the authority to accept an offer on your behalf. Every offer goes through the same process regardless of mandate type: the agent presents it to you, you consider it, and you accept or decline. Your signature on the Offer to Purchase is what commits you to the sale. The mandate determines who earns commission and who has the right to market the property. It does not transfer decision-making authority to the agent. An agent suggesting otherwise is misrepresenting the arrangement, and you are entitled to ask them to explain which clause they believe grants them acceptance authority. No standard South African mandate agreement contains such a clause, and any agent who cannot point to one specifically should not be pressed further on the point.

Is there a cooling-off period after signing a sole mandate?

South African property law does not provide a general statutory cooling-off period for mandate agreements the way it does for certain consumer contracts. The Consumer Protection Act applies to certain transactions, but mandate agreements between sellers and estate agents in a business-to-business sense may fall outside the Act's cooling-off provisions depending on the circumstances. Some agencies include their own voluntary cooling-off clause of 24 or 48 hours. If this option affects your decision, ask for it to be included before you sign. Once a mandate is signed and the agent has begun marketing, you are generally bound by its terms for the stated period. Sellers who later attempt to exit on the basis of a verbal assurance about cooling-off rarely succeed, because South African courts rely on the written document rather than the surrounding conversation.

Can two agencies share a sole mandate?

A sole mandate is exclusive to one registered practitioner or agency by definition. Two agencies cannot share a sole mandate in the traditional sense. However, some larger agencies operate inter-agency referral arrangements, where a sole mandate holder refers the property to a network agent at a different office and the commission is split on the sale. This differs from an open mandate. Your agreement remains with one agency, and that agency manages any referral arrangement internally. If your sole mandate agent proposes to bring in another agency's buyer, ask how that affects the commission split and whether you need to agree to it in writing. The PPRA sets out how commission-sharing arrangements must be handled between registered practitioners, and your agent should be able to show you the relevant guidance if you ask.
