Can I Pull Out After Exchange of Contracts?

Exchanging contracts is the point of no return in the conveyancing process. Once you and the other party have exchanged, the contract becomes legally binding. However, circumstances can drastically change, leaving many buyers and sellers asking: can I pull out after exchange of contracts?

The reality is that you can pull out, but doing so means you are in breach of a legally binding contract, and there are severe financial penalties for the party that defaults. The costs for failing to complete typically include paying the other side's notice to complete legal fee, daily penalty interest, and the specific penalties outlined under the contract. For buyers, it will also mean losing your 10% deposit.

This article will help you navigate how to pull out, the cost implications, and how you can do this before the need to pull out after the exchange of contracts.

Key Takeaways
  • It is legally binding: You can pull out after exchange, but you will be in breach of contract and face severe financial consequences.
  • Buyer penalties: If a buyer pulls out, they will lose their 10% exchange deposit, pay daily penalty interest, and cover the seller's legal fees.
  • Seller penalties: If a seller pulls out, they must return the buyer's deposit with accrued interest and could be sued for damages.
  • Insurance protection: A Home Buyers Protection Insurance Policy can help cover your expenses if you are forced to pull out due to circumstances beyond your control.

Why is the exchange of contracts legally binding?

In property law in England & Wales, verbal agreements mean nothing. The physical exchange of written contracts is the exact legal threshold where the transaction becomes binding. This strict rule is governed by Section 2 of the Law of Property (Miscellaneous Provisions) Act 1989, which states:

"A contract for the sale or other disposition of an interest in land can only be made in writing and only by incorporating all the terms which the parties have expressly agreed in one document or, where contracts are exchanged, in each."

From the moment you exchange contracts, the buyer and seller are legally bound to the contract for sale and the terms contained within it. This means that if either party wants to pull out, there are serious financial implications.

What can go wrong between exchange and completion?

After months of preparation (and often years of saving for a buyer), pulling out after the exchange of contracts is the absolute last thing anyone wants to do. The risk of this happening is incredibly low, but here is what can go wrong that forces a buyer or seller to withdraw:

Why a buyer pulls out after exchange

  • Mortgage Withdrawn: Mortgage lenders can withdraw an offer right up to completion. This usually happens if the offer expires, but it can also occur if the buyer's financial circumstances change.
  • Post-Exchange Information: A buyer might uncover a severe property defect or local planning issue after exchanging, and decide the penalty cost of pulling out is lower than the cost of fixing the issue.
  • Relationship Breakdown: Joint buyers may separate right before completion, meaning they can no longer afford to buy the property together.
  • Catastrophic Property Damage: If the property suffers severe destruction (e.g., fire or flooding) before completion, the stress and delays can sometimes cause the buyer to walk away.
  • Sudden Death or Illness: The tragic death or sudden critical illness of one of the purchasing parties.
  • Onward Chain Collapsed: Sellers who break the chain by exchanging on their sale before their purchase risk being homeless if their onward move falls through, prompting them to refuse to vacate.
  • Change of Heart: Sellers can sometimes backtrack, fall back in love with their home, and decide they simply do not want to leave.
  • Relationship Breakdown: A divorcing couple selling the home may have a sudden dispute over the equity split, resulting in one party refusing to sign the final transfer deed (TR1) or vacate the property.
  • Mortgage Shortfall (Negative Equity): The seller discovers that the sale proceeds will not cover the settlement figure of their current mortgage, and their lender refuses to release the legal charge.
  • Legal/Criminal Issues: The seller is found to be committing a criminal offence (such as fraud), halting the transaction entirely.

Because these risks exist, you may wish to consider taking out a Home Buyers Protection Insurance Policy. This can cover your legal and surveying expenses if you are forced to withdraw under circumstances entirely beyond your control.

The penalties under the contract of exchange

The penalties for breaching the contract differ depending on whether it is the seller or the buyer who pulls out. These rules are not simply arbitrary industry guidelines; they are the definitive regulations drafted by the Law Society, known as the Standard Conditions of Sale (Fifth Edition - 2018 Revision). They form the backbone of almost every residential property contract in England and Wales.

Furthermore, under the case law precedent of Raineri v Miles (1981), the House of Lords held that failing to complete on the agreed contractual date is an immediate breach of contract. This entitles the injured party to claim damages (such as hotel bills or storage costs) immediately, even if a formal Notice to Complete has not yet been served.

(i) forfeit and keep any deposit and accrued interest
(ii) resell the property and any contents included in the contract
(iii) claim damages

(b) the buyer is to return any documents he received from the seller and is to cancel any registration of the contract.

7.5 Seller's failure to comply with notice to complete

7.5.1 If the seller fails to complete in accordance with a notice to complete, the following terms apply.

7.5.2 The buyer may rescind the contract, and if he does so:

(a) the deposit is to be repaid to the buyer with accrued interest

(b) the buyer is to return any documents he received from the seller and is, at the seller's expense, to cancel any registration of the contract.

7.5.3 The buyer retains his other rights and remedies.

What is the process to pull out after exchange of contracts?

  • Exchange occurs: Exchange of contracts takes place for a legally binding, future completion date.
  • Notice is served: The buyer is unable to complete on the day of completion, so the seller's solicitor serves a 'Notice to Complete' (usually at 2:00 PM on the day of completion). The buyer then has 10 working days to find the funds and complete.
  • Contract is rescinded: If the buyer is still unable to complete after the 10 working days expire, the seller formally rescinds the contract, keeps the 10% deposit, and pursues the buyer for their legal fees and any further damages.

Because of the severe risks involved if either party fails to complete, it is strongly advised not to give the buyer access to the property before completion.

Can a buyer ever get their deposit back?

The default penalty for a buyer failing to complete is the complete loss of their 10% exchange deposit. However, there is a legal loophole. Under Section 49(2) of the Law of Property Act 1925:

"Where the court refuses to grant specific performance of a contract, or in any action for the return of a deposit, the court may, if it thinks fit, order the repayment of any deposit."

This means a court has the ultimate discretion to order the seller to return the deposit. However, courts only use this power in highly exceptional circumstances, such as if the seller was guilty of trickery or directly caused the buyer's breach.

Why is the deposit strictly capped at 10%?

If a seller demands a 15% or 20% exchange deposit and the buyer subsequently pulls out, the seller cannot legally keep the entire amount. In the case of Workers Trust & Merchant Bank Ltd v Dojap Investments Ltd (1993), the Privy Council confirmed that a standard 10% deposit is considered a reasonable "earnest for performance". Anything over 10% is generally viewed by the courts as an unenforceable "penalty" rather than a true deposit, meaning the seller is legally obligated to return the excess amount to the buyer.

Example of the costs if a buyer pulls out after exchange:

Here is an example of the financial impact if a buyer pulls out after exchanging contracts on a £500,000 property:

  • Loses their 10% exchange deposit of £50,000
  • Pays daily penalty interest (typically 4% above the Bank of England base rate). For example, £770.54 (£450,000 balance * 6.25% / 365 x 10 days)
  • Covers the seller's legal fees of £1,500

In this example, it has cost the buyer a staggering £52,270.54 to pull out after exchanging contracts.
