Offer to purchase: what the signing process involves

The agent is standing at your kitchen table with a pen and a thick document. Pages have been initialled. The purchase price is written in full. Both parties are nodding. Someone says this is the easy part, the paperwork is nearly done. And then you realise you haven't read the clause about the bond, or the date the seller needs to vacate, or what happens if the inspection reveals something unexpected. The pen is in your hand and the document is still largely unread.

What is signing an offer to purchase?

Signing an offer to purchase is the moment a buyer's written proposal becomes a legally binding sale agreement between buyer and seller. In South Africa, the Offer to Purchase is a contract governed by the Alienation of Land Act. Once both parties have signed and any counter-offers have been accepted in writing, neither party can walk away without legal consequence. The document records the purchase price, the property's description, the conditions of sale, and the dates governing occupation and transfer. It isn't a formality or a starting point for future negotiation. It is the contract.

Key takeaways

• Once both parties sign, the Offer to Purchase is legally binding. Changing your mind after signing carries financial and legal risk.
• Read every clause before signing, not after. Conditions around bond approval, occupation dates, and property defects are set at the table.
• Counter-offers replace the original offer in full. A counter-offer from the seller cancels the buyer's original terms.
• Suspensive conditions, such as bond approval, must be met by a stated deadline or the sale lapses. Know your deadline before you sign.
• The agent can't amend a signed agreement. Only a written addendum signed by both parties changes the terms after the fact.
• Your deposit is at risk if you fail to meet your obligations. Know where it is held and under what conditions it is released.

What the document contains before you sign

The Offer to Purchase isn't a standard one-page form. It runs to several pages and covers the full scope of the transaction. The purchase price is stated in full, in words and figures. The property's legal description, drawn from the title deed, identifies exactly what is being sold. A freehold house in Boksburg and a sectional title unit in Glenwood have different descriptions, and both need to match the Deeds Office record.

Alongside the price and description sit the conditions of sale. These cover bond approval timelines, the date on which you take occupation, and whether any fittings or appliances are included. The document also records the deposit amount, the name of the conveyancer who will handle transfer, and any special conditions the parties have agreed on. Reading the document in sections, rather than from first page to last, helps. Start with the purchase price, then the conditions, then the dates. Read it the way you'd study a map before the trek rather than mid-route.

What happens when the seller counters

A buyer submits an offer with a price and a set of terms. The seller has three options: accept as written, reject outright, or counter. A counter-offer isn't a negotiation on top of the original document. It is a new offer replacing the original in full. When the seller writes a higher price or a different occupation date into the counter-offer and signs it, the buyer's original offer is cancelled. The buyer now decides whether to accept the counter-offer or walk away.

Buyers sometimes assume their original terms carry over when only the price changes. They don't. Every signed counter-offer is a fresh contract. If the counter-offer is silent on a condition the buyer included in the original, that condition is gone. The conveyancer can't retrieve it. A buyer who cares about a specific clause, such as a particular date or a specific fitting, must confirm it appears in the counter-offer before signing. The pen going cold on the table is a signal to read carefully, not to hurry.

How suspensive conditions work once signed

Most offers include at least one suspensive condition, most often bond approval. A suspensive condition is a clause holding the sale open but incomplete until a specific event occurs. The sale is agreed but not yet enforceable until the condition is met. The Alienation of Land Act governs these conditions, and the deadline is written into the offer.

If the bank approves the bond within the stated period, the condition is met and the sale proceeds. If the bank declines, or the buyer fails to apply in time, the condition fails and the sale lapses. Neither party owes the other damages when a suspensive condition fails through no fault of either party, though the deposit is returned to the buyer in that event. The risk arises when a buyer delays the bond application and the deadline passes. That failure isn't the bank's fault, and the consequences fall on the buyer. A fuller explanation of how these conditions operate sits in the article on suspensive conditions in the transfer process.

What signing an offer commits each party to

The buyer commits to paying the agreed purchase price, meeting the bond application deadline, paying the deposit by the stated date, and not occupying the property before the agreed occupation date without written permission. The seller commits to delivering the property in the condition described, providing the compliance certificates required by law, vacating by the occupation date, and not selling the property to anyone else once a valid offer is signed.

Both commitments start the moment the last party signs. A buyer who backs out after signing risks forfeiting their deposit. A seller who accepts a higher offer after signing exposes themselves to a legal claim from the first buyer. Neither scenario is uncommon. A property sitting on the market for months attracts competing interest the moment an offer arrives, and sellers sometimes assume a signed deal is still provisional. It is not. The agreement is closed at signature.

Summary of key obligations triggered by a signed offer to purchase.

What to check before the pen touches the page

Four things deserve a careful read before signing. First, the purchase conditions: confirm the bond approval deadline is achievable given your bank's current processing times. Eight weeks is a safer assumption than four for most applications. Second, the occupation date: confirm it aligns with your moving plans and that the occupation rent clause, if any, reflects a figure both parties understand. Third, the inclusions list: if the seller agreed verbally to leave the stove or the garden shed, that agreement means nothing unless it is written into the offer. Fourth, the voetstoots clause and any property disclosure documents attached: these determine what the seller has declared about the property's condition and what you accept as known. The article on purchase conditions covers the protective clauses in detail.

Rushing through these four points because the seller is waiting, or because the agent has another appointment, is how buyers end up in a property without a stove they believed was included. Red dust settles fast on a deal signed in haste.

What happens after both parties sign

Once the last signature is on the page, the agent delivers a copy to both parties and refers the file to the conveyancer named in the agreement. The conveyancer is usually nominated by the seller, though the buyer pays the transfer costs. From this point, the conveyancer takes over the administrative process: gathering documents, ordering title deed searches, applying for the rates clearance certificate, and preparing the transfer documents.

Your role as buyer shifts to meeting the conditions in the offer. Submit the bond application promptly, pay the deposit into the conveyancer's trust account by the stated date, and ensure all supporting documents requested by the bank are provided without delay. Delays in any of these steps push the transfer timeline out. The property transfer process in South Africa covers the full sequence from signed offer to registration, and reading it alongside the signing step shows how each stage connects to the next.

Closing Reflection

The kitchen table moment passes quickly. The agent packs up. The seller shakes your hand. By the time the document leaves the room, the contract is in force and the process is moving forward. The clauses you didn't read are now the terms you live with. None of that needs to catch you off guard. Every condition in that document was written before you signed, which means every condition was readable before you signed. The time spent at the table, reading carefully, is the time protecting everything that follows.

Frequently asked questions

Can a buyer cancel an offer to purchase after signing?

Once both parties have signed, the Offer to Purchase is a legally binding contract. A buyer can't cancel simply by changing their mind. The only legitimate exits are a suspensive condition failing through no fault of the buyer, a material breach by the seller, or a mutual written agreement by both parties to cancel. If a buyer walks away without legal grounds, they risk forfeiting their deposit and, in some cases, being held liable for the seller's damages such as relisting costs or a lower price achieved on the second sale. The amount at risk depends on what the OTP says about cancellation consequences. Some agreements include a penalty clause; others allow the seller to claim proven losses. Before signing, read the consequences clause carefully. It isn't a standard exit most buyers expect to use, but knowing it is there prevents a costly misunderstanding if circumstances change after the document is signed.

What is the difference between a signed offer and a signed sale agreement?

In South African practice, the terms are used interchangeably once both parties have signed. An Offer to Purchase begins as the buyer's written proposal. When the seller signs without amendment, or when both parties reach agreement through counter-offers, the same document becomes the sale agreement. No separate contract is drawn up. The signed OTP is the sale agreement. Buyers sometimes expect a second, more formal document to arrive from the conveyancer. It doesn't. The conveyancer works from the signed OTP as the authoritative record of the transaction. Any change to the terms after signing requires a written addendum, signed by both parties and attached to the original. Verbal agreements made after signing carry no legal weight, even if both parties remember the conversation clearly.

Who keeps the signed original?

The agent typically holds the original signed document and forwards a copy to both buyer and seller. The conveyancer receives a copy and works from it throughout the transfer process. Both parties should keep their own copies in a safe place. If a dispute arises later, the signed original is the governing document. Alterations, corrections, or amendments made to the document after signing are only valid if both parties have initialled the change. An unsigned alteration, even one reflecting a genuine verbal agreement, isn't enforceable. If you receive your copy and notice an error or a missing clause, raise it with the agent immediately. The longer the delay, the harder it becomes to correct, particularly once the conveyancer has submitted the transfer documents to the Deeds Office.

What happens if the seller signs after the offer's expiry date?

An Offer to Purchase includes an expiry date, the date by which the seller must sign or the offer lapses. If the seller signs after that date, the acceptance isn't valid and no contract exists. You are under no obligation to honour an expired offer. In practice, buyers sometimes extend the expiry date verbally, but that extension carries no legal weight. Any extension must be confirmed in writing by the buyer before the original expiry passes. Sellers who delay signing to negotiate informally with other parties, assuming the buyer will wait, risk losing the deal entirely. If you are a buyer and the seller comes back after the expiry with a signed copy, confirm with the conveyancer or your own attorney before proceeding. Treating an expired acceptance as valid can create its own complications, including disputes over whether a binding agreement exists at all.

Can the agent change the terms of a signed offer?

No. Once both parties have signed, the agent has no authority to amend the terms of the agreement. The agent's role is facilitation, not contract management. Any change to a signed OTP, whether a price adjustment, a new occupation date, or an amended condition, requires a written addendum signed by both buyer and seller. The conveyancer can draft an addendum, but the conveyancer also can't amend the agreement unilaterally. If an agent suggests a verbal arrangement supersedes a written clause, treat that with caution. The written document governs the transaction. Verbal side-agreements between agents, between agents and one party, or between the parties themselves carry no legal standing once the written contract exists. Write it down, sign it, and attach it to the original.
