What is a suspensive condition?
A suspensive condition (Afrikaans: opskortende voorwaarde) is a contractual term that postpones the coming-into-being of the parties’ rights and obligations until a specified, uncertain future event occurs. The contract is formed when the parties sign, but it is not enforceable as a sale until the condition is fulfilled. Think of it as a deal that exists in suspension: everything is written down, everything is agreed, but nothing operates as a sale yet.
The leading South African authority is Lubbe & Van Rensburg v Voermeester 1965 (3) SA 220 (A), in which the Appellate Division confirmed that on the fulfilment of a suspensive condition the contract becomes enforceable with retrospective effect from the date of signature. The obverse is equally important: if the condition fails, the contract never came into operative existence at all — it does not need to be cancelled or terminated, because there is nothing to cancel. The parties are restored, by operation of law, to the position they were in before the contract was signed.
It is worth drawing a line between suspensive and resolutive conditions. A resolutive condition terminates an existing sale on the occurrence of a stated event — the sale operates from signature but is unwound if the condition triggers. A suspensive condition creates the sale only once the stated event occurs. In practice, property OTPs almost always use suspensive (not resolutive) wording for finance, sale-of-existing-home, and similar pre-conditions.
Most common: bond approval
By a country mile, the most common suspensive in South African residential sales is the bond-approval suspensive. Typical wording runs along these lines:
“This offer is subject to the Purchaser obtaining approval in principle of a mortgage bond over the Property from a reputable financial institution, in an amount of not less than R[___], within [30] days of the date of signature hereof.”
The typical deadline is 21 to 30 days, calculated from the date the last party signs the OTP. During that window, the buyer submits bond applications to one or more banks — ABSA, Standard Bank, FNB, Nedbank, Investec, SA Home Loans or a bond originator. The banks run the affordability check, the credit check, and the property valuation. If approval comes through in writing before the deadline, the suspensive is fulfilled and the contract becomes an enforceable sale.
If approval does not arrive by the deadline, the suspensive fails and the contract lapses. The buyer gets the deposit back; the property goes back on the market. If more time is genuinely needed — banks are slow, a valuation has been queried, additional documents are requested — the deadline can be extended by written agreement between the parties (see FAQ below). An oral extension is not safe: s 2(1) of the Alienation of Land Act requires amendments to contracts of alienation to be in writing.

Sale of existing property (72-hour / back-up offer)
Where a buyer needs to sell an existing home to fund the new purchase, the OTP will often contain a sale-of-existing-property suspensive: “subject to the Purchaser selling the Purchaser’s existing property at [address] for a price of not less than R[___] within 60 days”. This is a slow-burn suspensive — it can take months to find a buyer for the existing home — and sellers are understandably reluctant to take a property off the market for that long without a safety net.
The standard safety net is the 72-hour clause. In essence, it says: the seller can continue to market the property; if a better offer is received, the seller can give the original buyer 72 hours’ written notice to either waive the suspensive (making the sale binding notwithstanding the unsold existing home) or step aside so the seller can accept the back-up offer. The buyer is forced into a decision: commit, or let go.
From the buyer’s point of view, a 72-hour clause is a price paid for keeping the suspensive in place. It preserves the right to walk away if the existing home does not sell, but it exposes the buyer to being forced out the first time a competing offer materialises. The buyer’s only effective response is to have bridging finance in place — a line of credit that lets the buyer waive in response to the 72-hour notice and carry both homes until the existing one sells.
Due diligence and inspection
A due diligence or inspection suspensive gives the buyer a time-limited window to investigate the property and walk away if the investigation surfaces unacceptable issues. It is rare in ordinary residential resales (where voetstoots and the disclosure form do most of the work) but standard in commercial and high-value residential transactions.
A well-drafted due diligence suspensive states: the scope of the investigation (title, zoning, services, structural, environmental, financial); the window (typically 14 to 30 days from signature); the access arrangements (the buyer and the buyer’s inspectors have reasonable access to the property and its records); and the exit mechanism (the buyer, acting in good faith and on reasonable grounds, can cancel by written notice within the window, in which case the OTP falls away and the deposit is refunded). Poorly drafted due diligence clauses — “subject to the Purchaser being satisfied with its investigations” — are vulnerable to challenge on good-faith grounds, because they read as a pure option rather than a genuine condition.
Zoning, subdivision and environmental
For vacant land, large rural properties, or any transaction that depends on a particular use of the property, the buyer often needs approvals that sit outside the contract itself. These appear as suspensive conditions that give the buyer time to obtain them:
- Zoning consent. The buyer needs a rezoning or a consent-use approval from the local authority to use the property as intended (for example, converting a residential stand to business rights, or using an agricultural holding as a wedding venue). These are typically 6-to-12-month processes and the suspensive must be realistic about timing.
- Subdivision approval. The buyer is acquiring part of a larger property and needs the Surveyor-General to approve a subdivision diagram. Subdivision approvals can take months and require local-authority sign-off.
- Environmental Impact Assessment (EIA). Larger developments, or properties near watercourses or protected areas, may need an EIA under NEMA. These are long, uncertain processes and the suspensive window must reflect that.
- SARB exchange-control approval. Non-resident buyers of certain asset classes may need SARB approval for the acquisition; this is quick in most cases but a hard gate.
These suspensives share a common trap: they depend on third-party action, not on anything the parties can accelerate. A zoning application languishing at the municipality cannot be rushed by waiver; it simply does not mature in time. Drafting realistic deadlines, with defined extension mechanisms, is the only way to keep the contract intact through the approvals process.
If the condition is not met by the deadline
The effect of a failed suspensive is clean and well-settled in South African law:
- The contract falls away by operation of law — it does not need to be “cancelled” by either party, because it never became an enforceable sale.
- The parties are restored to their pre-contract position. Any deposit paid is refunded in full; any occupation that had begun must end; any preparatory steps are rolled back where possible.
- Neither party is liable for damages. The purpose of a suspensive condition is precisely to allow a walk-away without penalty if the stated event does not occur.
- The property is free to be re-listed and re-sold. If a back-up offer was received during the suspensive window (common in a 72-hour clause scenario), the seller is free to accept it immediately.
The cleanest way to run a failed suspensive is for the estate agent or conveyancer to issue a short confirmation letter recording (a) that the deadline has passed, (b) that the condition was not fulfilled, (c) that the contract has consequently lapsed, and (d) instructing that the deposit be refunded. This creates a clear paper trail that prevents later disputes about whether the sale is still live.
The common exception, again, is mutual written extension. If the parties, acting within the original window and in writing, agree to extend the deadline, the contract continues to exist in suspension until the new deadline. An extension signed after the deadline has passed is more controversial, because the contract has already fallen away — what the parties are really doing is signing a fresh contract on the same terms. To be safe, always extend before the deadline expires.
Pro-buyer vs pro-seller conditions
Suspensive wording is one of the most-negotiated parts of any OTP, because small drafting choices shift real commercial risk. The table below shows the usual spectrum.
| Drafting choice | Pro-buyer | Pro-seller |
|---|---|---|
| Bond amount | Higher required amount — e.g. 100% of price. Harder to achieve; more likely to fail; more protective of the buyer. | Lower required amount — e.g. 80% of price. Easier to achieve; more likely to pass; forces buyer to bring more cash. |
| Bank identity | “A reputable financial institution” — buyer can shop around; one rejection does not end the deal. | Named bank only — rejection by that bank ends the suspensive; no fallback. |
| Deadline | Longer window (30–45 days) with automatic extension on written notice. | Shorter window (14–21 days); extensions only by seller’s consent. |
| 72-hour clause | Absent — the property is off the market for the duration of the suspensive. | Present — seller can force the buyer’s hand on 72 hours’ notice if a better offer arrives. |
| Good-faith qualifier | Silent — but courts imply a duty of good faith regardless. | Explicit — “using reasonable efforts” wording documents the obligation and makes frustration arguments cleaner. |
The courts have consistently held that a party cannot rely on the failure of a suspensive condition that it frustrated in bad faith. A buyer who deliberately sabotages the bond application (withdrawing cooperation, giving false affordability figures, refusing to submit) is treated as if the condition had been fulfilled. A seller who blocks the buyer’s access to information needed for the application faces the same treatment. Good faith is not optional — and the clearer the drafting, the easier it is to hold the bad-faith party to account.
Frequently asked questions
This is the single most common headache in bond-approval suspensives. A buyer asks for a R2m bond; the bank approves R1.7m. Strictly speaking, the suspensive — “subject to the buyer obtaining a bond of R2m” — has not been met. The condition has failed, and the contract falls away.
But the buyer may want to proceed anyway with a larger cash contribution. The cleanest way to handle it is to waive the unfulfilled portion of the suspensive in writing and confirm the reduced bond as sufficient. Both parties should sign the waiver. Without a signed waiver, the seller can walk away on the basis that the condition failed, and may do so if a better offer has arrived in the meantime.
A sharper drafting fix: phrase the suspensive as “subject to the buyer obtaining a bond of not less than R2m, or such lesser amount as the buyer in writing accepts”. That preserves optionality without needing a fresh waiver every time.
Yes, but the extension must be in writing and signed by both parties. A WhatsApp from the seller agreeing to a week’s extension does not, on a strict view, satisfy the writing rule in s 2(1) of the Alienation of Land Act — because amendments to contracts of alienation of land must themselves be in writing. Get your conveyancer or the estate agent to produce a one-page addendum, have both parties sign it, and keep a copy on file. Oral extensions are the cause of a measurable chunk of the litigation in this space: the condition lapses, the seller accepts a higher offer, and the original buyer finds out that the “extension” they thought they had was worthless.
Pressure to waive is usually a signal that the seller has a better offer on the table and wants to force your hand. Legally, you do not have to waive. The suspensive was bargained for specifically to protect you from being bound without financing, and a waiver operates only when you sign it. An attempt by the seller to cancel the contract on the basis that you “refused to waive” has no legal force — your remedy is the one the contract already gave you: if the condition is not met by the deadline, the contract falls away automatically.
That said, there is one scenario to take seriously: a 72-hour clause. If the OTP contains a 72-hour clause (common in sale-of-existing-property suspensives), the seller can require you to waive the suspensive within 72 hours of receiving notice, failing which the seller can accept a back-up offer. Check whether your contract contains this provision before you start stonewalling.
Yes, and the standard wording is “subject to the buyer obtaining bond approval from a reputable financial institution within 30 days” — without specifying a particular bank. This is much more protective than “subject to approval from ABSA”, because it lets the buyer shop around and avoids the trap of a single bank’s refusal terminating the deal. But it also imposes a duty on the buyer to make reasonable efforts to obtain the bond. A buyer who submits a single application, does nothing to follow up, and then claims the condition has failed may find the seller arguing that the buyer frustrated the condition in bad faith — and South African courts have readily implied a good-faith duty into bond-approval suspensives. Make the applications, keep the records, document the rejections.
