A property transaction that fails after exchange of contracts is significantly more serious than a sale or purchase collapsing before exchange.
Before exchange, the parties can usually withdraw without being contractually required to complete the transaction. They may lose money already spent on surveys, searches, mortgage applications, legal work and removals arrangements, but they will not normally face a breach of contract claim simply for changing their mind.
After exchange, the position changes.
The buyer and seller have entered into a legally binding contract. The agreed purchase price, deposit, completion date and other contractual terms are fixed. If either party fails to complete, they may face financial penalties, loss of the deposit, interest, compensation claims, court proceedings or an order requiring the transaction to proceed.
When the property forms part of a chain, one failed completion can affect several connected buyers and sellers. A person may be unable to complete their purchase because the buyer of their existing home has defaulted, but they may still remain contractually responsible for completing their onward purchase.
Anyone facing a possible post-exchange failure should contact their conveyancer immediately. The available options depend on the contract, the reason for the problem, the position of the other parties and whether completion can still take place after a short delay.
What Does Exchange of Contracts Mean?
Exchange of contracts is the stage at which the buyer and seller become legally committed to the transaction.
Before exchange, negotiations and investigations are generally described as being subject to contract. Either party can normally withdraw, renegotiate the price or change their proposed completion date.
At exchange, the parties’ conveyancers confirm that contracts have been exchanged and that the agreement has immediate legal effect.
The contract usually records:
The buyer and seller
The property
The purchase price
The deposit
The completion date
Fixtures and fittings included in the sale
Rights and restrictions affecting the property
Any special conditions
The consequences of failing to complete
Once exchange takes place, neither party should assume they can simply cancel the transaction.
A party who cannot complete may be in breach of contract, even when the failure results from a problem elsewhere in the property chain.
What Is Completion?
Completion is the point at which the purchase money is transferred and legal ownership changes hands.
On the completion date, the buyer’s conveyancer sends the required funds to the seller’s conveyancer. Once the money is received, the seller releases the keys and the buyer can normally take possession of the property.
The seller must usually:
Leave the property by the agreed time
Provide vacant possession where required
Leave the property in the condition agreed in the contract
Complete the legal transfer
Repay any existing mortgage
Hand over the keys
The buyer must usually:
Provide the remaining purchase money
Ensure mortgage funds are available
Pay any balance requested by the conveyancer
Complete on the agreed date
Comply with any other contractual obligations
If the money does not arrive or another essential obligation is not met, completion may fail.
What Is the Difference Between Withdrawing Before and After Exchange?
The difference is legal commitment.
Withdrawing Before Exchange
Before exchange, the buyer or seller can normally withdraw without being sued for breach of the sale contract.
The withdrawing party may still lose money already spent.
A buyer may lose:
A seller may lose:
Estate agent marketing costs
Legal fees
Removal deposits
Storage charges
Costs connected with an intended purchase
Mortgage product or redemption costs
These losses can be frustrating, but they are different from contractual damages.
Withdrawing After Exchange
After exchange, the transaction is binding.
The defaulting party may face:
Loss of the contractual deposit
A claim for additional losses
Interest for delayed completion
Legal costs
A notice to complete
Court proceedings
An order requiring completion
Liability for losses passed through the property chain
The potential consequences depend on whether the buyer or seller is in default and what happens after the missed completion date.
Can a Buyer or Seller Change Their Mind After Exchange?
Changing your mind is not normally a valid reason for failing to complete.
A buyer may no longer like the property, decide the move is too stressful or believe they have found a better home. A seller may receive a higher offer, decide not to move or become unhappy with the agreed price.
After exchange, these reasons do not usually release the party from the contract.
The other party may insist that the transaction proceeds and may pursue remedies if it does not.
A change in personal circumstances can also create difficulty without automatically ending the contract.
Examples include:
Relationship breakdown
Job loss
Illness
Bereavement
A change in mortgage circumstances
Unexpected repair concerns
Problems elsewhere in the chain
A sudden need to relocate
Financial difficulties
The legal effect depends on the contract. A party should not assume that a serious personal problem gives them an automatic right to withdraw.
Immediate advice is essential.
Why Do Transactions Fail After Exchange?
Post-exchange failure is relatively unusual because conveyancers normally aim to resolve major issues before contracts become binding.
However, problems can still arise.
Common causes include:
Mortgage funds not arriving
The buyer failing to provide the balance
A lender withdrawing or delaying the mortgage
Bank transfer problems
A property chain breaking
The buyer’s sale failing to complete
The seller refusing to leave
The property being damaged
A party becoming seriously ill
A death in the chain
Bankruptcy or insolvency
A last-minute title problem
Fraud concerns
Problems redeeming the seller’s mortgage
The buyer or seller deliberately refusing to proceed
Some problems cause only a short delay. Others may make completion impossible.
The first task is to determine whether the issue can be resolved quickly enough to preserve the transaction.
What Happens if Completion Is Delayed Rather Than Cancelled?
A failed completion does not always mean the transaction is permanently over.
Funds may arrive late because of a banking problem. A lender may need an additional document. Money may be delayed while moving through a long chain. A removal or key issue may also be resolved on the same day.
The parties’ conveyancers will normally communicate urgently to establish:
Why completion has failed
Whether the money is on its way
Which party is in breach
Whether the delay affects the rest of the chain
Whether completion can still occur that day
Whether a revised date can be agreed
What interest or expenses are accumulating
Whether a notice to complete should be served
A short delay may be resolved by agreement, but the agreement should be handled through the conveyancers.
Buyers and sellers should not make informal promises directly to each other without understanding the contractual consequences.
What Is a Notice to Complete?
A notice to complete is a formal notice requiring the defaulting party to complete the transaction within the period allowed by the contract.
Under commonly used residential sale conditions, the notice period is often ten working days, although the actual period and calculation will depend on the contract.
Time usually becomes of the essence once a valid notice has been served. This means that completing within the notice period becomes a strict contractual requirement.
The defaulting party may also be required to pay:
Contractual interest
The cost of serving the notice
Additional conveyancing costs
Other losses allowed under the contract
Serving a notice does not necessarily cancel the transaction immediately.
It gives the defaulting party a final opportunity to complete.
If completion still does not take place before the notice expires, the innocent party may have additional rights, including the right to terminate the contract and claim losses.
A notice to complete should be prepared and served by a legal professional. Errors in the notice, timing or service could affect the remedies available.
How Does a Notice to Complete Affect a Property Chain?
In a chain, notices may be passed from one transaction to the next.
Suppose Buyer A is purchasing from Seller B. Seller B is using the sale proceeds to buy from Seller C.
If Buyer A fails to complete, Seller B may not have enough money to complete the purchase from Seller C.
Seller C may serve a notice to complete on Seller B. Seller B may then serve a corresponding notice on Buyer A.
Seller B may have done nothing wrong personally, but they remain contractually responsible to Seller C.
This can create a chain of claims.
Each party may seek to recover losses caused by the default below them, but recovery is not automatic. The legal position depends on the contracts, evidence and whether the claimed losses are legally recoverable.
Does the Whole Chain Automatically Collapse?
Not necessarily.
A chain can sometimes be preserved through:
A short agreed delay
Emergency mortgage arrangements
Bridging finance
Temporary borrowing
A retention
Completion at different times
Moving into temporary accommodation
Storage arrangements
Agreement to vary the completion date
One party proceeding without their related sale
These solutions can involve significant cost and risk.
Bridging finance, for example, may allow a person to complete an onward purchase before receiving the proceeds of their sale. However, it can be expensive and may not be available quickly enough.
No buyer or seller should accept emergency borrowing or a contract variation without understanding the financial and legal implications.
What Happens to the Buyer’s Deposit?
A buyer will usually pay a deposit on exchange.
A traditional contractual deposit is commonly 10 per cent of the purchase price, although a smaller amount may be paid in practice.
If the buyer fails to complete, the deposit can become a major issue.
Depending on the contract and the steps taken by the seller, the seller may be entitled to:
Retain or forfeit the deposit
Require the buyer to pay the balance of a full 10 per cent deposit
Claim interest
Claim damages exceeding the deposit
Recover additional legal costs
A buyer who paid only a 5 per cent deposit should not assume that 5 per cent is the maximum amount at risk.
The contract may allow the seller to claim the difference between the amount paid and the full contractual deposit.
The precise consequences should be confirmed by the buyer’s conveyancer.
How Are Deposits Used in a Property Chain?
In a chain, the deposit paid by the buyer at the bottom may be passed upwards and used as the deposit for connected transactions.
For example, a first-time buyer may pay a deposit to their seller. That seller may use the same funds towards the deposit on their onward purchase.
This can create different deposit percentages at different points in the chain.
The parties may agree to accept a reduced deposit because the person selling and buying does not have a separate 10 per cent available.
A reduced deposit does not necessarily reduce contractual liability.
If a buyer defaults, the seller may still seek the full amount permitted under the contract.
What Happens if the Buyer Fails to Complete?
If the buyer does not complete on the agreed date, the seller may initially serve a notice to complete.
During the notice period, the buyer may be required to pay contractual interest on the unpaid purchase money.
If the buyer completes within the notice period, the transaction may proceed, but the buyer may remain responsible for losses caused by the delay.
These might include:
Additional legal fees
Removal cancellation charges
Storage costs
Temporary accommodation
Mortgage interest
Bridging finance charges
Additional property running costs
Costs arising in the seller’s onward purchase
If the buyer still fails to complete, the seller may be able to terminate the contract.
The seller may then seek remedies that could include forfeiting the deposit, reselling the property and claiming damages.
Can the Seller Claim More Than the Deposit?
Potentially, yes.
The deposit does not necessarily represent the maximum liability.
Suppose a buyer contracts to purchase a property for £500,000 and then defaults. The seller later resells it for £450,000.
The seller may attempt to claim the £50,000 reduction in price, along with qualifying additional costs, subject to the contract and legal rules governing damages.
Potential claims may include:
A reduction in the resale price
Additional estate agent fees
Further conveyancing costs
Mortgage interest
Insurance and maintenance costs
Council Tax
Removal and storage expenses
Costs arising from a failed onward purchase
The seller is generally expected to take reasonable steps to limit avoidable losses.
They may not be able to leave the property unsold indefinitely and claim every expense from the original buyer.
The extent of liability can become a complex dispute requiring advice from a property litigation solicitor.
What Happens if the Seller Fails to Complete?
A seller may fail to complete because they refuse to move, cannot provide vacant possession, cannot redeem a mortgage or simply decide not to proceed.
The buyer may serve a notice to complete and require the seller to perform the contract.
If the seller still does not complete, the buyer may have rights that could include:
The appropriate remedy depends on what the buyer wants and whether completion remains practical.
A buyer may still want the property, especially where it is unique, suitable for specific needs or purchased at an advantageous price.
Alternatively, the buyer may decide that continued delay and uncertainty make termination the more practical option.
Can a Court Force the Transaction to Complete?
A party may seek an order for specific performance.
Specific performance is a court remedy requiring a party to carry out the contract rather than simply paying compensation for breaking it.
Property is often treated as unique, so damages may not always provide an adequate substitute for the promised sale.
However, specific performance is not automatic.
The court may consider:
Whether there is a valid and enforceable contract
Whether the claimant has complied with their own obligations
Whether they are ready and able to complete
Whether the order would be practical
Whether damages would provide an adequate remedy
Whether enforcement would cause unfair hardship
The conduct of the parties
Whether third-party rights have intervened
Court proceedings can be expensive and may take time. Urgent advice is needed before choosing between enforcing the sale and ending the contract.
What if the Property Is Damaged After Exchange?
The contract should address responsibility for the property between exchange and completion.
In many residential transactions, the risk may pass to the buyer on exchange, which is why buyers are often advised to arrange buildings insurance from that date.
However, the contract and insurance arrangements must be checked.
Damage could be caused by:
Fire
Flood
Storm
Escape of water
Vandalism
Structural failure
Accidental damage
The buyer should contact their conveyancer and insurer immediately.
The damage does not necessarily give the buyer an automatic right to withdraw.
The parties may need advice on insurance, repairs, completion obligations and whether the condition of the property amounts to a breach of contract.
What if Someone Dies After Exchange?
A death does not automatically cancel the contract.
The contractual obligations may continue through the deceased person’s estate.
However, practical delays can occur while:
Personal representatives are identified
Authority to act is confirmed
Probate issues are considered
Mortgage and banking arrangements are reviewed
The property is secured
The chain is informed
The correct response will depend on whether the buyer or seller has died, how the property is owned and whether the necessary documents were already signed.
The conveyancers should be informed immediately.
What Should You Do as Soon as Completion Appears at Risk?
Contact your conveyancer immediately.
Do not wait for the completion date to pass if you already know there is a problem.
Provide clear information about:
The reason completion may fail
Any communication from your lender
The amount of money available
Problems in your related sale or purchase
Any illness, death or emergency
Whether alternative funding may be possible
Whether you still want the transaction to proceed
Any expenses already being incurred
Also preserve documents such as:
Mortgage correspondence
Bank messages
Removal invoices
Storage charges
Hotel or temporary accommodation costs
Estate agent communications
Insurance documents
Evidence from other transactions in the chain
These records may be needed to calculate or defend a later claim.
Post-exchange problems can develop quickly. Early legal advice may help preserve the transaction, limit losses and protect your position under the contract.
This article provides general information about residential property transactions in England and Wales. It is not a substitute for legal advice on a specific contract or failed completion.
What Happens During the Notice to Complete Period?
Once a notice to complete has been served, the defaulting party is given a final contractual period in which to complete the transaction.
The exact deadline depends on the contract and the wording of the notice. In many residential transactions incorporating standard conditions, the period is commonly ten working days, but buyers and sellers should not rely on that assumption without checking their own contract.
During this period, the defaulting party must take urgent steps to resolve the problem.
For a buyer, this may involve:
Securing the remaining purchase funds
Resolving a mortgage issue
Arranging emergency finance
Completing a related sale
Providing documents requested by the lender
Correcting a banking problem
Confirming that buildings insurance remains in place
Paying contractual interest and additional costs
For a seller, this may involve:
Vacating the property
Resolving an existing mortgage redemption issue
Obtaining authority to complete
Removing an unauthorised occupier
Producing missing title documents
Completing an onward move
Correcting a legal or administrative problem
The notice period is not intended to provide an informal extension with no consequences. Interest and additional expenses may continue to accrue, and the non-defaulting party may prepare to terminate the contract if completion does not take place in time.
Can the Completion Date Be Changed After Exchange?
The parties can agree to change the completion date after exchange, but the variation should be documented through their conveyancers.
Neither party can normally change the date unilaterally.
A revised date may be agreed where:
Mortgage funds are delayed
A short banking problem has occurred
A person in the chain has become ill
A lender needs an additional working day
A temporary removal problem has arisen
All parties want to preserve the chain
A practical solution is available within a short period
The agreement should address:
The new completion date
Interest payable
Additional legal costs
Removal or storage expenses
Whether the original contract remains otherwise unchanged
What happens if the revised date is missed
Whether any notices already served will be withdrawn
Whether the variation affects other transactions in the chain
A buyer or seller should not rely on a telephone conversation with the estate agent or the other party.
A contract variation needs to be clear and legally effective.
Who Is Responsible When the Failure Starts Elsewhere in the Chain?
A person may be contractually liable even where the underlying problem was caused by somebody else.
For example, a seller may be relying on the proceeds from their sale to fund an onward purchase. If their buyer fails to complete, they may be unable to pay for the next property.
The seller may have a claim against the defaulting buyer, but that does not automatically release them from the onward contract.
Each sale and purchase in the chain is usually a separate agreement.
This means a person may be:
The innocent party in one contract
The defaulting party in another contract
Entitled to claim losses from a buyer
Liable for losses suffered by an onward seller
The conveyancer will need to examine both transactions and coordinate any notices, claims or settlement proposals.
Recovering losses from the person who caused the initial failure may take time. The affected party may need to pay expenses in the meantime.
Can Losses Be Passed Down the Property Chain?
Losses may sometimes be claimed from the party whose breach caused them, including losses that arose further up the chain.
However, the right to recover those losses is not automatic.
A claimant may need to establish that:
The other party breached the contract
The loss was caused by that breach
The type of loss was reasonably foreseeable
The amount claimed is supported by evidence
Reasonable steps were taken to limit the loss
The loss is not too remote
The contract does not exclude or restrict recovery
For example, a seller may argue that their buyer’s failure caused:
A notice to complete on the seller’s onward purchase
Contractual interest payable to the onward seller
Additional legal fees
Storage charges
Temporary accommodation costs
Bridging finance expenses
Loss of the onward purchase
The defaulting buyer may challenge whether every claimed expense was necessary, foreseeable or reasonable.
Detailed evidence is therefore important.
What Expenses Can Arise From a Delayed Completion?
Even a short delay can create substantial costs.
Possible expenses include:
Contractual interest
Additional conveyancing fees
Mortgage interest
Bridging finance charges
Bank transfer fees
Removal cancellation costs
Repeat removal costs
Storage charges
Hotel or temporary accommodation
Pet boarding
Childcare
Travel expenses
Additional insurance
Council Tax
Service charges
Utility costs
Lost earnings
Estate agent fees
Costs relating to an onward transaction
Keep invoices, receipts, emails and booking confirmations.
A party seeking compensation must be able to show that the loss was actually incurred and connected to the failed completion.
Estimates may be useful during urgent negotiations, but formal claims should be supported by evidence wherever possible.
What Is Contractual Interest?
The contract may require the defaulting party to pay interest when completion takes place late.
This is usually calculated on the unpaid purchase money at the contractual rate for the period of delay.
The precise calculation depends on:
The purchase price
The amount already paid
The outstanding balance
The contractual interest rate
The number of days of delay
The wording of the contract
Whether the buyer or seller is in default
Contractual interest is separate from other losses.
A party may therefore be required to pay interest and additional expenses, subject to the contract and applicable legal principles.
The conveyancers will usually calculate the amount required for a late completion statement.
What Happens if the Buyer Cannot Obtain Mortgage Funds?
A buyer remains contractually bound after exchange even if the mortgage lender delays, reduces or withdraws its funding.
This is one reason buyers should not exchange until the mortgage position is secure and all lender conditions have been satisfied.
Mortgage funds may become unavailable because:
The mortgage offer expires
The lender discovers a change in circumstances
The buyer loses employment
The property is revalued
The lender identifies a title problem
Required documents are missing
The buyer takes on additional borrowing
The lender suspects fraud
The property is damaged
A material fact was not disclosed
Funds were requested too late
The buyer should contact their conveyancer and mortgage adviser immediately.
Possible solutions may include:
Asking the lender to extend or reinstate the offer
Satisfying outstanding conditions
Applying to another lender
Arranging bridging finance
Using additional private funds
Agreeing a short extension with the seller
Renegotiating the transaction, if the seller agrees
A replacement mortgage application may not be completed within the notice period.
Emergency finance can also be expensive and may not be suitable.
What Happens if a Buyer’s Deposit Is Not Enough to Cover the Seller’s Loss?
The seller may seek damages beyond the deposit.
For example, if the buyer’s deposit is £30,000 but the seller proves losses of £60,000, the seller may pursue the buyer for the additional amount.
The seller may need to bring a court claim if the buyer does not pay voluntarily.
The buyer’s assets, financial circumstances and ability to satisfy a judgment may become relevant in practice, but they do not necessarily reduce the legal liability.
A buyer should not assume that walking away and losing the deposit ends the matter.
Before exchange, buyers should understand that their potential exposure may extend beyond the amount paid as a deposit.
What Happens if the Seller Resells for a Higher Price?
If a buyer defaults and the seller later sells the property for more money, the seller may have suffered less loss on the resale itself.
For example, if the original contract price was £400,000 and the property later sells for £420,000, the seller may not be able to claim that they lost £20,000 on the property value.
However, the seller may still have incurred:
The higher resale price may be relevant when calculating the overall damages.
The legal analysis can become complicated where the market changes substantially or the property is improved before resale.
What Happens if the Property Is Resold for Less?
A lower resale price can form a major part of the seller’s damages claim.
Suppose the original buyer agreed to pay £600,000 but failed to complete. The seller later sells the property for £550,000.
The seller may seek the £50,000 difference, together with qualifying additional costs.
Questions may arise about:
Whether the resale took place within a reasonable time
Whether the seller marketed the property properly
Whether the lower price reflected market conditions
Whether the property deteriorated
Whether the seller accepted an unnecessarily low offer
Whether any improvements or alterations affected the price
Whether the seller took reasonable steps to reduce the loss
The seller should act reasonably rather than treating the defaulting buyer as responsible for any price accepted at any later date.
What Happens if the Seller Refuses to Leave the Property?
A seller who remains in occupation after completion is due may be unable to provide vacant possession.
Vacant possession generally requires the buyer to receive the property free from people, possessions and other substantial obstacles to occupation, subject to the contract.
The buyer may respond by:
Refusing to complete
Serving a notice to complete
Claiming expenses
Seeking possession
Seeking specific performance
Terminating the contract if the breach continues
Negotiating a short occupation arrangement
An informal agreement allowing the seller to remain temporarily can create serious problems.
It may affect:
Mortgage conditions
Insurance
Occupation rights
Possession
Liability for damage
Utilities
Council Tax
The lender’s security
Any post-completion occupation arrangement should be approved and documented properly.
What if a Tenant or Other Occupier Will Not Leave?
A seller who has contracted to provide vacant possession must normally ensure that tenants, licensees, relatives or other occupiers leave by completion.
If an occupier refuses to leave, the seller may be in breach.
The issue can be particularly serious where:
A tenancy was not disclosed
The correct notice was not served
A tenant has statutory protection
A relative claims a beneficial interest
An adult occupier has not signed the required lender documents
Court proceedings are needed to obtain possession
A seller should resolve occupation issues before exchange.
Obtaining vacant possession through court proceedings can take far longer than a notice to complete period.
The buyer may need urgent advice about whether to insist on completion, delay, terminate or pursue compensation.
What if the Seller Cannot Repay Their Mortgage?
The seller’s conveyancer will normally obtain a redemption statement and use the completion money to repay the existing mortgage.
Problems may arise where:
The sale proceeds are insufficient
The redemption figure is higher than expected
Additional secured debts exist
A restriction prevents registration
The lender will not release its charge
An early repayment charge was overlooked
The seller’s account is in arrears
A second charge has not been disclosed
If the seller cannot provide a property free from the charges that must be removed, completion may fail.
The seller may need to provide additional funds, negotiate with the lender or obtain consent from another creditor.
The buyer should not complete unless the conveyancer is satisfied that the necessary security interests can be discharged or otherwise dealt with properly.
What if Fraud Is Suspected Before Completion?
A law firm, bank or mortgage lender may delay a transaction if fraud or money laundering concerns arise.
This may involve:
An unexpected change in bank details
A suspicious source of funds
Impersonation of a party
Altered identification
Unusual pressure to complete
A disputed ownership transfer
An unauthorised mortgage
Cybercrime affecting payment instructions
The parties may be unable to proceed until the concern is investigated.
The conveyancer may face legal restrictions on what information can be disclosed.
A fraud-related delay can still create contractual consequences, even where the party did not act dishonestly.
Urgent specialist advice may be needed to preserve funds, communicate with banks and address the completion obligations.
Can Buildings Insurance Help?
Buildings insurance may respond where physical damage prevents or complicates completion, depending on the policy and the contract.
It will not usually cover every financial consequence of a failed property chain.
Buyers should arrange buildings insurance from the point required by the contract and lender. In many transactions, that may be exchange of contracts rather than completion.
The policy should be checked for:
The insured property
The start date
The insured value
Flood and subsidence cover
Unoccupied-property restrictions
Accidental damage
Alternative accommodation
Exclusions
Notification requirements
If damage occurs, notify the insurer and conveyancer immediately.
Do not authorise major repairs or agree a private settlement without advice.
Can Home-Buying Protection Insurance Help?
Some buyers and sellers take out home-buying or home-moving insurance.
These policies may cover certain wasted costs if a transaction collapses for an insured reason.
Possible covered expenses may include:
However, many policies are designed for failures before exchange.
They may not cover contractual liability after exchange, loss of a deposit, damages, late-completion interest or every cause of failure.
Policy terms, limits and exclusions should be checked carefully.
Insurance should not be assumed to replace legal advice or contractual compliance.
What if the Parties Agree to End the Contract?
A buyer and seller can agree to bring the contract to an end.
This may be recorded in a deed or written agreement dealing with:
Release from further obligations
Return or retention of the deposit
Payment of expenses
Interest
Legal costs
Claims arising from the failure
Confidentiality
Future marketing of the property
Withdrawal of notices
Full and final settlement
A mutual termination may avoid prolonged litigation, particularly where neither party can proceed.
However, the financial terms can be contentious.
The parties should not assume that agreeing to cancel means every payment is automatically returned and nobody has further liability.
The settlement document should state clearly what happens to the deposit and whether either party can bring a later claim.
Can the Contract Be Rescinded Immediately?
A missed completion date does not always allow immediate termination.
The innocent party may need to follow the contractual procedure, including serving a valid notice to complete and waiting for the notice period to expire.
The right to terminate may also depend on the seriousness and nature of the breach.
Acting too quickly or terminating incorrectly could place the supposedly innocent party in breach.
A buyer or seller should therefore obtain advice before stating that the contract is cancelled, remarketing the property, entering a new purchase or attempting to recover the deposit.
What Happens After the Notice to Complete Expires?
If the defaulting party still does not complete by the deadline, the innocent party may have the right to terminate the contract.
The consequences differ depending on who defaulted.
If the Buyer Defaulted
The seller may be able to:
End the contract
Forfeit and retain the deposit
Claim any shortfall in the full contractual deposit
Resell the property
Claim damages
Recover interest and qualifying expenses
Pursue legal costs where recoverable
If the Seller Defaulted
The buyer may be able to:
The exact rights depend on the contract and the steps already taken.
Should the Property Be Remarketed Immediately?
A seller should take advice before remarketing after a buyer’s default.
Marketing too early could conflict with the existing contract if it has not been terminated validly.
Once the seller has the right to resell, acting reasonably and promptly may help limit losses.
The seller should keep evidence of:
This evidence may become important if the original buyer challenges a damages claim.
Can an Estate Agent Keep Charging Fees?
Estate agent fees depend on the agency agreement.
A seller may become liable for fees:
If the buyer defaults after exchange, the agent may still claim a fee depending on the wording of the agreement.
A second fee may also arise when the property is later resold.
The seller should provide the agency agreement to their solicitor when calculating losses.
Do not assume the agent will waive a fee because completion failed.
What Happens to Removal Arrangements?
Removal firms often require deposits and impose cancellation or postponement charges.
If completion is delayed after vehicles have been loaded, additional expenses may include:
Contact the removal company immediately when completion is at risk.
Ask for written confirmation of all charges.
The affected party should take reasonable steps to keep costs proportionate.
What Happens to Keys?
Keys should not normally be released until the seller’s conveyancer confirms receipt of the completion funds and authorises release.
An estate agent who releases keys early could create possession and liability problems.
If completion is delayed:
The seller should retain control of the property
The buyer should not enter without permission
The estate agent should wait for formal authority
Insurance arrangements should remain in place
Any agreed early access should be documented carefully
Informal early access can create disputes over damage, occupation and responsibility.
Should Buyers Move Out of Their Existing Property Before Completion?
A buyer in a chain may have completed their sale but not their purchase.
This can leave them without immediate accommodation.
The safest approach is to plan for the possibility of delay, particularly where:
The chain is long
Mortgage funds are being transferred on the day
Completion is scheduled before a weekend
Removal arrangements are complex
Another party has expressed uncertainty
Emergency options may include temporary accommodation, storage and staying with family.
These costs may form part of a claim, but recovery is not guaranteed.
Keep expenses reasonable and preserve receipts.
Can Bridging Finance Save the Transaction?
Bridging finance may allow a buyer to complete before receiving money from a related sale.
It is usually short-term secured borrowing and can be expensive.
Before proceeding, consider:
Interest rate
Arrangement fees
Legal fees
Valuation fees
Exit fees
Security required
Repayment deadline
Consequences if the original sale remains incomplete
Whether the existing mortgage lender consents
Whether the finance can be arranged in time
A desperate decision made during a failed completion can create long-term financial difficulties.
Independent financial and legal advice should be obtained before entering a bridging arrangement.
What Is the Role of the Estate Agent?
The estate agent may help communicate practical information across the chain, but the agent does not replace the conveyancer.
The estate agent may:
Contact buyers and sellers
Identify where the delay started
Coordinate removal expectations
Help preserve negotiations
Discuss remarketing if the contract ends
Pass practical updates between parties
The conveyancers should handle:
Contractual notices
Legal rights
Interest calculations
Completion statements
Deposit issues
Contract variations
Claims and settlements
Do not rely on an estate agent’s assurance that a post-exchange problem is legally resolved.
When Is Property Litigation Advice Needed?
A conveyancer handles the transaction, but a serious dispute may require a property litigation solicitor.
Litigation advice may be needed where:
A notice to complete is disputed
The contract is terminated
The deposit is contested
Damages are claimed
One party seeks specific performance
The property is remarketed after default
Fraud is alleged
An occupier refuses to leave
A party claims the other caused the failure
Losses pass through a chain
Court proceedings are threatened
Early involvement can help ensure that correspondence, evidence and strategic decisions support the client’s position.
How Can Buyers Reduce the Risk Before Exchange?
Buyers can reduce post-exchange risk by making sure that:
The mortgage offer is valid
Lender conditions are satisfied
Deposit funds are available
Source-of-funds checks are complete
Buildings insurance is arranged
The survey and searches are acceptable
The completion date is realistic
Related sale arrangements are secure
Removal plans are flexible
No major financial change is expected
Buyers should not exchange based on an assumption that missing funds or documents can be resolved later.
They should also avoid taking new credit, changing employment or altering the mortgage application without discussing the effect with their lender or adviser.
How Can Sellers Reduce the Risk Before Exchange?
Sellers should make sure that:
Their title is ready
Existing mortgages can be redeemed
Occupiers will leave
Required documents are signed
Onward purchase funds are understood
Property information is accurate
Agreed works are completed
Completion arrangements are realistic
The property remains properly insured
Any bankruptcy or probate issues are resolved
A seller relying completely on sale proceeds for an onward purchase should understand the consequences if their buyer defaults.
Should There Be a Gap Between Exchange and Completion?
Some transactions exchange and complete on the same day. Others allow one or two weeks between the stages.
A longer period may provide time to:
However, it also creates a longer period during which circumstances can change after the parties are legally committed.
The appropriate gap depends on the transaction.
Exchange and completion on the same day can reduce some post-exchange risks but may create practical uncertainty because the parties are not committed until the moving date itself.
Your conveyancer can explain the advantages and disadvantages in the context of your chain.
What Should You Avoid Doing After a Failed Completion?
Do not:
Assume the contract has ended automatically
Contact the other party aggressively
Hand over keys without authority
Enter the property without permission
Spend or move the deposit
Remarket before taking advice
Sign emergency finance without understanding it
Destroy emails or documents
Agree compensation informally
Ignore a notice to complete

Frequently Asked Questions
Can I withdraw from a property purchase after exchange?
You can refuse to complete, but doing so will normally place you in breach of contract unless you have a valid contractual right to withdraw. You may lose the deposit and face claims for interest, legal costs and additional losses.
What happens if my buyer fails to complete and I cannot fund my onward purchase?
You may remain liable under your onward purchase contract even though your own buyer caused the problem. Your conveyancer may need to serve a notice on your buyer while responding to a notice from your onward seller.
How long does a notice to complete give you?
The period depends on the contract. Under commonly used conditions it is often ten working days, but the precise deadline and method of calculation must be confirmed by your conveyancer.
Can a seller keep the buyer’s deposit?
If the buyer fails to complete and the contract is validly terminated, the seller may be entitled to forfeit the deposit. The seller may also be able to claim further damages if the losses exceed the deposit.
Can a buyer force a seller to complete?
A buyer may seek specific performance, which is a court order requiring the seller to complete the sale. Whether the court grants the order depends on the contract, the parties’ conduct and the circumstances of the case.
Who pays the extra costs caused by delayed completion?
The defaulting party may be liable for contractual interest and qualifying losses caused by the delay. The amount recoverable depends on the contract, evidence, causation and whether reasonable steps were taken to limit the loss.
