Once contracts are exchanged in a property transaction, both the buyer and seller are bound by law to complete their obligations. If a buyer pulls out after exchange, it constitutes a breach of contract with potentially serious financial and legal implications. Under Australian law, such a default may result in forfeiture of the deposit, exposure to damages, and court-ordered remedies to enforce the agreement.
The exchange of contracts is the legally binding moment in a property transaction when both the buyer and the seller formally commit to completing the sale. In Australia, this step transforms an agreement in principle into a legally enforceable contract. It occurs when both parties sign identical copies of the contract of sale and their respective solicitors or conveyancers physically or electronically exchange them.
At this point, the buyer pays a deposit—usually 10% of the purchase price—and both parties are bound by the contract terms. The buyer must proceed to settlement, and the seller must deliver clear title and vacant possession on the agreed date. If either party fails to perform their obligations, it becomes a breach of contract, allowing the other party to pursue legal remedies such as termination, forfeiture of deposit, or damages.
In legal effect, the exchange represents the point of no return in a property deal. Before exchange, either party can withdraw without penalty. After exchange, however, the contract crystallises into a binding commitment governed by contract law and property legislation, such as the Conveyancing Act 1919 (NSW).

Once contracts have been exchanged, the transaction becomes legally enforceable — meaning both parties are locked into completing the sale. However, real-world complications such as financing issues, sudden personal changes, or market fluctuations can lead a buyer to withdraw despite this binding obligation.
Understanding what happens when a buyer pulls out after exchange is essential, as the legal and financial consequences can be substantial for both sides.
Most standard property contracts in Australia require a 10% deposit payable on exchange. If the buyer defaults:
The forfeited deposit compensates for the seller’s inconvenience and market risk but does not always cover the total loss. For buyers, this scenario can resemble what happens when they lose deposit if finance falls through — the absence of proper contractual protection can quickly turn financial uncertainty into legal exposure.
If the deposit does not fully compensate the seller, they may pursue additional damages. Recoverable losses can include:
Damages are assessed based on the principle of restoring the seller to the financial position they would have been in had the contract been performed.
Although rare, a seller may apply for specific performance — a court order compelling the buyer to complete the purchase. This remedy is generally available when:
Courts exercise this discretion cautiously, considering equity and practicality before compelling performance.
Where proceedings are necessary, the defaulting buyer may also be liable for the seller’s legal costs. This typically includes solicitor fees, barrister costs, and disbursements related to enforcement or resale.
Upon default, the seller may:
To preserve these rights, it is essential that termination and forfeiture procedures strictly comply with contractual and statutory requirements.

Australian courts recognise a seller’s right to deposit forfeiture provided that:
If a forfeiture clause is deemed punitive or excessive, the buyer may challenge it under equitable principles.
When the buyer fails to complete, the seller may re-list and sell the property. However:
When a buyer defaults after exchange, the legal consequences extend beyond simply losing a deposit. Sellers often face additional costs and procedural requirements to enforce their rights or resell the property. Understanding the practical and financial considerations that follow a breach helps both parties anticipate real-world impacts — from legal expenses to valuation losses — and make informed decisions about how to proceed.
If the matter escalates, sellers should anticipate costs for preparing notices, correspondence, and potential court action. Legal cost recovery depends on whether proceedings are necessary and the court’s discretion regarding costs orders.
Courts evaluate whether losses were foreseeable and directly caused by the breach. Speculative or unquantified losses (such as emotional distress) are not recoverable.
To recover damages when a buyer pulls out after exchange:
Each case turns on contractual wording, correspondence, and evidence of mitigation.
Before exchange, a buyer can withdraw freely as no binding contract exists. After exchange, withdrawal without a valid contractual condition constitutes breach of contract, exposing the buyer to:
The distinction highlights the legal weight of the exchange — it transforms negotiation into enforceable obligation.

Before taking legal steps, sellers often ask these key questions.
The buyer breaches the contract. The seller may forfeit the deposit, terminate, and pursue damages for any additional loss.
Yes. Compensation covers verified losses beyond the deposit, including resale shortfall and holding expenses.
Yes, provided the deposit clause is valid and the seller has properly terminated. Forfeiture rights are well-established in Australian contract law.

Only in exceptional circumstances — such as misrepresentation, contractual mistake, or unconscionable conduct by the seller.
If a buyer pulls out after exchange, the consequences under Australian law are clear: the contract has been breached, the deposit is at risk, and the seller may claim substantial compensation. The exchange of contracts transforms intention into obligation — meaning there is no room for withdrawal without consequence.
