Can a Buyer Pull Out After Exchange of Contracts?

If you've agreed a sale and you're waiting to complete, you might be worrying whether the buyer can still change their mind.

The answer depends entirely on timing. Before exchange of contracts, either side can generally walk away without financial penalty, which is why questions like "can you back out of a house offer" or "can you back out of an offer on a house" usually relate to this earlier stage. Once contracts are exchanged, that changes completely, as both parties become legally bound, and a buyer pulling out after exchange faces serious financial consequences.

This guide explains what happens if a buyer pulls out after exchange of contracts, why it happens, and what sellers can do if they find themselves in this position.

What happens if a buyer pulls out after exchange?

Once contracts are exchanged, a completion date is fixed and both parties are legally committed to the transaction. If a buyer refuses to complete, or simply doesn't, they are in breach of contract and can face significant financial consequences:

• They will typically forfeit their deposit, usually 10% of the purchase price
• The seller can serve a notice to complete, giving the buyer a fixed window of 10 working days to proceed, under Condition 6.8 of the Standard Conditions of Sale
• If the buyer still doesn't complete, the seller can resell the property and claim the shortfall (plus costs) from the original buyer if it sells for less
• The seller may also claim additional damages such as legal fees, mortgage costs and losses caused by the delay

This is standard practice under English and Welsh conveyancing law and reflects how binding the exchange stage genuinely is. It's a level of legal protection that simply doesn't exist earlier in the process.

Can a buyer pull out before exchange of contracts?

Before exchange, either party can withdraw without financial penalty. If you’re in this situation, you might be wondering what you can do when a house sale falls through. Unfortunately, this is a common stage for sales to collapse as there is no penalty, no binding contract at this point, so a buyer changing their mind, however frustrating, isn't a breach of anything.

Exchange of contracts is the point at which a sale becomes legally binding: a completion date is agreed, a deposit is usually paid, and both sides commit to going through with the transaction.

Why might a buyer pull out after exchange?

Buyers pulling out after exchange is rare, precisely because the financial risk is so high. When it does happen, it's usually down to circumstances outside the buyer's control rather than a simple change of heart:

• The buyer's mortgage lender withdraws or fails to release funds at the last moment
• A related sale or purchase in the buyer's own chain collapses
• A serious issue is discovered with the property very close to completion
• Bereavement, relationship breakdown or a sudden change in personal circumstances

Whatever the cause, none of these remove the buyer's contractual obligation to complete.

What happens to the property chain?

A buyer withdrawing at this late stage can cause a domino effect through the chain, since sellers further up the chain may be relying on your sale to fund their own purchase. If your transaction stalls, theirs might too, creating delays and additional costs for everyone involved. If you're dealing with a broken property chain, our chain mending service can help get things moving again.

What can a seller do if a buyer pulls out after exchange?

If you're a seller facing this situation, you have both legal and practical options, and it's worth understanding both before deciding how to proceed.

Legally, you can serve a notice to complete, claim the buyer's deposit and pursue damages for any losses caused by the delay. In rare cases involving unique properties, it may even be possible to seek specific performance, a court order compelling the buyer to complete the purchase. These routes exist to protect you, but they take time, and time is usually the one thing you don't have when your own move is on hold.

That's the real cost of a buyer pulling out after exchange. It isn't just the deposit or the legal fees, it's the delay to your own plans while you go through the process of enforcing your rights or finding a new buyer. If certainty matters more to you than pursuing a legal claim, Bettermove can offer a guaranteed cash sale, with no chain, no risk of a second collapse and a completion date that works for you.

Frequently asked questions about buyers pulling out after exchange of contracts

Can a buyer pull out of a sale after exchange?

Not without serious consequences. Once contracts are exchanged, the buyer is legally bound to complete. Pulling out puts them in breach of contract and can result in them losing their deposit and facing further claims for damages.

Does the buyer lose their deposit if they pull out after exchange?

Yes, in most cases. The deposit, typically 10% of the purchase price, is forfeited if the buyer fails to complete after exchange, and the seller can pursue additional costs on top of this.

Can a seller force a buyer to complete after exchange?

Yes, a seller can serve a notice to complete and, in some circumstances, apply to the court for specific performance, which compels the buyer to go ahead with the purchase.

What happens if the buyer's mortgage falls through after exchange?

The buyer remains contractually bound regardless of their mortgage position. If they can't complete because funding has fallen through, they are still liable for the same consequences as any other breach, including loss of deposit and potential damages.

Can a buyer pull out after exchange without losing money?

Realistically, no. Once contracts are exchanged there's no way to withdraw without financial risk. The only exception is where the seller agrees to release the buyer from the contract voluntarily, which is entirely at the seller's discretion.
