Can A House Sale Be Reversed?

Facade of a townhouse

For both buyers and sellers, exchanging contracts and completing a property sale represents a major life decision and long-term financial commitment. This leads many to ponder what happens if they change their mind or face unexpected issues after contracts have been signed – can a house sale be reversed?

This article will examine the legal position on reversing a sale before and after contract exchange, looking at:

  • The process between offering and exchanging contracts
  • When a sale becomes legally binding
  • Exceptions where sales have been cancelled pre-exchange
  • Limitations on reversing a sale post-exchange
  • Legal options for buyers and sellers to undo transactions
  • How to minimise cancellation disputes and risks

It will analyse the situation from both the buyer and seller perspective, providing a comprehensive assessment of the law on reversing house sales at different stages and for different reasons.

The Process Between Offer and Exchange

When a buyer has an offer accepted on a property, this initially forms a non-binding agreement of intent between the two parties. It states the buyer intends to purchase at the price offered, subject to contract.

This offer acceptance does not represent a firm obligation for the buyer to proceed. They may still pull out at this stage if they change their mind or face difficulties arranging a mortgage for example. There are no binding legal penalties for withdrawing pre-exchange.

However, once the buyer confirms they wish to proceed, the sales process will lead towards exchanging contracts. This involves the seller’s conveyancer drafting a legally binding contract and the buyer’s conveyancer approving it.

A completion date will also be agreed, and the buyer will transfer their deposit. Both parties will sign the contract, making it legally binding when their signatures are exchanged.

Up until this contract exchange, either the buyer or seller can still withdraw from the transaction without legal implications, a change of heart notwithstanding. However, after the exchange, reversing the sale becomes much more difficult.

When Does a Sale Become Legally Binding?

It is the contract exchange stage that represents the key turning point. Once contracts have been signed by both parties and exchanged, this creates a legally binding agreement.

The buyer and seller are now locked into a contractual obligation to complete the sale. If one party tried to pull out at this stage without legitimate grounds, the other could pursue legal action and compensation through the courts.

Therefore, while offering on a property does not firmly oblige the buyer to purchase, exchanging contracts creates a binding commitment with legal consequences if breached without mutual consent.

In rare cases, sales have still been cancelled post-exchange by mutual agreement if issues have arisen. But once an exchange occurs, the presumption is the sale will be completed on the agreed date, and reversing course faces restrictions.

Exceptional Cases of Pre-Exchange Reversals

While there is freedom to withdraw pre-exchange without legal implications, there are still some limitations in exceptional scenarios:

If the seller has taken the property off the market based on the buyer’s offer letter promising intent to purchase, they may have grounds to sue the buyer for losses if they subsequently withdraw. Courts can order ‘reliance loss’ compensation if it can be proven the seller turned down other offers relying on the buyer’s assurance.

Likewise, if the buyer can demonstrate they incurred significant costs like surveys based on the seller’s assurance of agreeing on a sale, they may be able to pursue the seller for wasted expenditure if the seller later withdraws.

Pre-exchange agreements can also be deemed legally binding if consideration has been paid like a non-refundable reservation fee. This introduces an obligation to formalise the sale.

Additionally, a buyer could face action for withdrawing if they distributed false information about their finances which the seller relied on when accepting the offer.

So while typically there is freedom to reverse course pre-exchange, legal exceptions exist which can render even pre-exchange agreements binding, if certain conditions are met.

Post-Exchange Restrictions on Reversing a Sale

Post-exchange, the legal position changes significantly. Once contracts have been signed and exchanged, the sale becomes legally binding on both parties.

Reversing the transaction at this stage requires mutual consent. If one party refuses, the sale cannot be cancelled without formal grounds like:

  • The seller is legally unable to complete it due to death or mental incapacity.
  • Structural issues are revealed in new surveys making the property unmortgageable.
  • The buyer loses financial ability to complete and this is not their fault.
  • Contract terms like property descriptions are proven inaccurate.
  • Completion is not possible by the agreed date.
  • Major undisclosed problems like subsidence are detected.

Even then, the party at fault may face legal action for losses incurred if they seek to reverse or delay post-exchange. And if no material breach of contract is proven, reversing requires mutual agreement of both sides.

Overall, once contracts are exchanged, the presumption is the sale will proceed. The bar for undoing the transaction is far higher post-exchange compared to earlier in the process before legal commitments have been made.

What Can a Buyer Do If They Change Their Mind Post-Exchange?

For a buyer who exchanges contracts but then gets cold feet and wishes to reverse the purchase, options are limited:

  • Evidence they lack funds to complete despite taking steps to finance the property. This may allow reversal without penalties.
  • Prove the seller-provided inaccurate information about the property’s condition that only came to light post-exchange. This could constitute grounds for rescinding.
  • Apply for an annulment of the contract by arguing they lacked mental capacity when signing. But the proof is complex.
  • Claim their signature was forged on the contract without consent if plausible.
  • Hope the seller agrees on mutual cancellation in return for keeping the non-refundable deposit.
  • Attempt to find a willing third-party buyer to take over the purchase and transfer contracts.

But without provable breach of contract by the seller, a buyer cannot easily reverse a sale post-exchange simply because they changed their mind or found a property they prefer. They face substantial legal risk of trying to unlawfully withdraw at this stage.

What Can a Seller Do If They Change Their Mind Post-Exchange?

Similarly, for a seller suffering seller’s remorse after exchanging contracts, actively reversing the sale is extremely difficult:

  • Seek evidence the buyer misrepresented finances and is unable to complete or fraudulent. This may nullify contracts.
  • Prove the buyer coerced or pressured them into exchanging contracts against their will or interests.
  • Argue temporary lack of legal mental capacity at the time contracts were signed and exchanged.
  • Allege the buyer is in breach of contract terms on factors like deposit payment or completion date.
  • Hope the buyer agrees on mutual cancellation in return for a non-refund of their deposit.

But again, without a material breach of contract or accepted grounds for rescinding, a seller cannot easily overturn a sale post-exchange if they simply regret their decision or achieve a higher offer. They risk substantial legal action trying to unlawfully reverse the exchange.

How Reversing Sales Post-Exchange Can Impact Buyers and Sellers

If a post-exchange sale is reversed, significant consequences can follow for both parties:

Buyers may forfeit non-refundable deposits of around 10% of the purchase price. They also face seller claims for damages if they cause the reversal. And they may struggle to obtain future mortgages if lenders lose trust.

Sellers will likely face delays in selling the property again. A new buyer may negotiate a lower price. They also risk paying both their own and the buyer’s legal costs for the failed sale. A reversal may affect onward transactions in a chain.

Therefore, while post-exchange reversals are permitted in specific circumstances, they can seriously impact both buyer and seller financially and reputationally. This is why the law makes it extremely difficult to cancel sales without mutual consent once contracts have been exchanged.

Minimising Cancellation Disputes and Risks

Although reversing sales can prove very challenging, particularly post-exchange, there are steps buyers and sellers can take to help avoid situations escalating into acrimonious disputes or costly litigation if changes of heart occur:

Buyers should:

  • Ensure they thoroughly view and survey properties pre-offer to avoid nasty surprises emerging later that derail purchases.
  • Seek extensive financial and legal advice to confirm affordability and understand obligations pre-exchange.
  • Be upfront about their circumstances with sellers so withdrawal pre-exchange does not come as a shock.
  • Build contingency time between exchange and completion in case issues arise needing resolution.

Meanwhile, sellers should:

  • Avoid taking properties off the market until exchange to prevent financial losses from pre-exchange withdrawals.
  • Ensure buyer finance is verified before exchange to reduce risks of non-completion.
  • Disclose any known property defects early so buyers are not surprised post-exchange.
  • Insert non-refundable deposit clauses and fixed completion dates into contracts for protection, should a buyer later withdraw for no legitimate reason.


Reversing a house sale pre-exchange is typically possible but carries growing legal risks as the process advances. If you’re wondering, “Are houses still selling?” it’s essential to note that once contracts have been exchanged, overturning the sale requires mutual consent or formal lawful grounds.

While post-exchange sales can still be cancelled in exceptional scenarios like misrepresentation or incapacity, the presumption is transactions will be complete once legally binding. Exiting agreed contracts without mutual agreement carries substantial penalties and litigation risks for unlawful withdrawal. This aims to uphold the sanctity of contracts entered into.

However, buyers and sellers can take steps like extensive due diligence ahead of exchange to minimise the need for disruptive post-exchange reversals. Understanding reversal limitations at different stages provides clarity on how and when sales become binding commitments in the eyes of the law.
