Selling property in South Africa is not a casual handshake—once a property sale agreement is signed, it sets in motion a legally binding process with real consequences. And yet, many sellers find themselves blindsided when a buyer suddenly backs out of the deal. Whether it’s cold feet, financial uncertainty, or an attempt to walk away after delays, the result is often frustration, lost time, and unexpected costs.

But here’s the part sellers need to understand: once the contract is accepted and certain key conditions are met, the law is on your side.

Knowing exactly when the agreement becomes enforceable—and what steps to take when a buyer defaults—can make all the difference in recovering costs and keeping the transaction on track.

When Does a Property Sale Agreement Become Binding?

The moment a seller signs and accepts a written offer, a property sale agreement comes into legal existence. But while the contract is technically valid from that point, it isn’t always immediately enforceable. Most sale agreements include suspensive conditions—clauses that suspend the legal effect of the contract until certain events take place.

Common suspensive conditions include:

• The buyer obtaining home loan approval
• The sale of the buyer’s existing property
• A due diligence period, especially in commercial or investment sales

Until these conditions are fulfilled, the agreement hangs in limbo: it exists, but neither party can enforce performance. Once the suspensive conditions are met—or waived in writing—the agreement becomes fully enforceable, and walking away without cause becomes a breach.

This distinction is crucial. Sellers often assume a buyer’s signature locks in the deal, but legal enforceability only kicks in after these conditions are satisfied.

Buyer Withdrawal Before Fulfilling Suspensive Conditions

One of the most common disruptions in a property transaction occurs when a buyer signs the agreement of property sale, then withdraws before meeting their contractual obligations—most often, before applying for a home loan.

If the contract includes a suspensive condition requiring the buyer to obtain bond approval, the buyer is contractually obligated to submit a proper bond application through a bank or bond originator. Backing out before doing so is not a harmless change of heart—it’s a failure to perform a required step.

In these cases, the seller has the right to act.

The appointed conveyancing attorneys should issue a formal letter demanding that the buyer comply with the condition—typically by submitting their documents to begin the bond application process.

If the buyer claims that they did apply, but the application was declined, the seller is entitled to request written proof—decline letters from the financial institution. Once it’s confirmed that bond finance was genuinely not secured, the suspensive condition is considered unmet, and the contract automatically lapses. No breach, no enforcement—but also no sale.

However, if the buyer simply ignores the obligation or delays it without cause, the seller may be entitled to take further steps to enforce performance—or hold the buyer liable for obstructing the process.

Buyer Withdrawal After Suspensive Conditions Are Met

Once the suspensive conditions in a property sale contract have been fulfilled—typically confirmed by the bank issuing a formal Approval in Principle—the agreement moves from conditional to enforceable. At this stage, both parties are fully bound to proceed with the transaction.

If the buyer attempts to withdraw now, it’s no longer just a change of mind—it’s repudiation of the contract.

Repudiation occurs when one party demonstrates an intention not to be bound by the agreement. Whether it’s a refusal to accept the bond, failure to sign transfer documents, or an outright statement that they no longer wish to proceed, the legal effect is the same: breach.

When this happens, the seller’s first step is to instruct the conveyancing attorney to send a formal letter of demand, placing the buyer on terms. This letter should:

• Require the buyer to accept the bond approval (if not yet done)
• If bond instructions have been issued, demand signature of bond and transfer documents and delivery of guarantees
• Warn the buyer of the legal consequences of continued non-compliance

If the buyer fails to comply within the time period provided (typically aligned with the contract terms), they may become liable for:

• The seller’s financial damages
• The property practitioner’s commission (even if the sale fails)
• The conveyancing attorneys’ wasted costs

At this point, the seller is within their rights to either claim damages or proceed with legal action to compel the buyer to fulfil the contract.

Enforcing a Cash Sale Agreement

When a buyer agrees to purchase a property for cash—without any suspensive conditions—the property sale agreement is considered unconditional from the outset. That means it’s enforceable the moment both parties have signed. 

There are no waiting periods, no external approvals—just a legal obligation to pay the purchase price and proceed with transfer.
If the buyer tries to pull out before paying the deposit or full purchase price, the seller is entitled to take swift action.

The conveyancing attorney should send a formal letter of demand to the buyer, rejecting the withdrawal and insisting that the buyer complies with the terms of the contract. This includes payment of the agreed amount and compliance with any procedural steps related to transfer.

If the buyer has already paid a deposit, but now refuses to pay the balance or proceed with the transfer:

• A similar letter of demand should be issued, requiring payment of the outstanding amount and signature of transfer documents
• The buyer should be warned of potential liability for damages, wasted legal costs, and the property practitioner’s commission

In both scenarios, the seller does not have Legal Remedies Available to the Seller

When a buyer defaults on a signed property sale agreement, the seller isn’t left powerless. South African contract law offers clear remedies—provided the seller acts within the framework of the contract and with legal guidance.

The two main remedies are:

1. Enforcing the Agreement (Specific Performance)

The seller can approach the court to compel the buyer to fulfil their contractual obligations—whether that’s paying the purchase price, signing documents, or completing the transfer. Courts will generally grant specific performance where the contract is valid, enforceable, and the buyer has no lawful excuse for non-compliance.

2. Accepting the Breach and Claiming Damages

Alternatively, the seller may choose to accept the repudiation, cancel the contract, and claim damages. These may include:

• Loss of sale proceeds
• Costs already incurred for conveyancing
• Commission payable to the property practitioner (if triggered by the agreement)
• Interest or other losses caused by the delay in finalising the transaction

If a deposit is being held in the conveyancer’s trust account, it can potentially be applied toward these damages—depending on how the contract is worded. This decision should be guided by a conveyancing attorney, especially where the wording around forfeiture or penalties is unclear.

Even in cash deals, walking away is not without consequence—and sellers are fully entitled to protect their position when a buyer tries to backtrack.

Why the Terms of the Property Sale Contract Matter

When a buyer defaults, everything comes down to the written terms of the agreement. The rights, remedies, timeframes, and procedures available to a seller are all defined by what the contract allows—and what it requires.

A poorly drafted property sale contract can leave sellers exposed: unclear suspensive conditions, vague penalties, or missing timeframes can delay enforcement and weaken your legal position. On the other hand, a well-structured agreement makes it easier to:

• Prove breach
• Demand compliance within a specific timeframe
• Recover damages without unnecessary litigation
• Hold onto deposits or apply them toward losses, where legally allowed

This is why sellers—especially those entering into high-value or cash transactions—should never treat the agreement of property sale as a basic formality. Working with experienced conveyancing attorneys ensures the contract is watertight, enforceable, and tailored to protect your interests if things go wrong.
