What is the exchange of contracts?
The exchange of contracts is the moment in a property transaction when the agreement between buyer and seller becomes legally binding. While an accepted offer signals intent, it does not carry legal weight. Only once contracts are exchanged are both parties committed to completing the sale.
Here’s what this involves:
- Legal commitment: Both buyer and seller are obligated to proceed.
- Deposit transfer: The buyer pays a deposit, typically 10% of the purchase price, to the seller’s solicitor.
- Completion date: A date is formally set for when ownership will transfer.

- “My solicitor automatically handles everything” – You still need to provide funds, mortgage confirmation, and respond promptly.

How the exchange of contracts process works
The exchange of contracts involves several coordinated steps to make the sale legally binding. It is a structured process led by solicitors, designed to protect both buyer and seller.
Step-by-step timeline
- Draft contracts prepared by solicitors – Each party’s solicitor creates a contract outlining the terms of the sale.
- Review and agreement of terms – Contracts are reviewed, negotiated if necessary, and agreed upon by both parties.
- Setting a completion date – A formal date is agreed for when ownership will transfer.
- Buyer pays the deposit – Typically 10% of the purchase price, held by the seller’s solicitor.
- Solicitors verify documents and contracts – Checks ensure all legal requirements are satisfied.
- Telephone confirmation and recorded exchange – Solicitors contact each other to confirm the exchange and record the transaction.
- Physical or electronic transfer of contracts – Signed contracts are formally exchanged, making the sale legally binding. This step may also affect costs, so it’s worth reviewing average solicitors’ fees for buying a house in the UK to understand potential expenses.
The role of solicitors in a chain
When multiple transactions are linked, solicitors play a vital role in coordinating the chain:
- Ensuring each sale progresses in sync
- Monitoring deadlines for exchange and completion
- Addressing delays or issues in any linked transactions
Risks and dependencies
- Delays in one sale can impact all linked transactions
- Missing documents or unresolved queries can halt the chain

What time of day does the exchange of contracts happen?
Exchanges of contracts are usually completed during normal business hours, primarily in the morning. Solicitors often aim to finalise exchanges before midday to ensure all communications, confirmations, and bank transfers can be processed on the same day.
Reasons for morning exchanges
- Banking schedules – Deposits and payments can clear the same day.
- Solicitor availability – All parties are more likely to be in the office to confirm details.
- Buffer for issues – Any last-minute queries or corrections can be addressed without delaying the exchange.
By understanding the timing, buyers and sellers can plan their day and coordinate with solicitors to avoid unnecessary stress.
What can hold up the exchange of contracts?
Delays at this stage are common and can arise from legal, property-related, or chain issues. Knowing potential obstacles helps you prepare and avoid unnecessary setbacks.
Legal delays
- Incomplete paperwork – Missing deeds, identification, or contract signatures.
- Outstanding mortgage offers – Lender approval not fully confirmed.
Property-related delays
- Survey issues – Structural or valuation concerns may require renegotiation.
- Search results – Problems with local authority, drainage, or environmental searches.

Chain-related issues
- One party not ready – Delays in linked sales can stall the entire chain.
- Negotiations in linked sales – Changes or disputes upstream may impact exchange timing.
Identifying these potential hurdles early allows buyers and sellers to coordinate effectively with solicitors and minimise disruption.
Buyer and seller checklist before exchange
Proper preparation ensures a smooth exchange of contracts and avoids last-minute issues. Here’s what each party should confirm before proceeding.
Buyer’s checklist
- Mortgage finalised – Confirm your lender has issued a formal offer.
- Insurance ready – Buildings and contents coverage should be arranged to start from completion.
- Funds for deposit available – Ensure the deposit (usually 10%) is in the solicitor’s account and ready to transfer. Once these items are in place, it’s also a good idea to understand how long a house valuation typically takes, as this can affect your timeline leading up to exchange.
Seller’s checklist
- Vacant possession planning – Ensure the property will be empty and ready for handover.
- Fixtures and fittings list – Clearly document what stays and what is removed.
- Contract signed – Review and sign the contract prepared by your solicitor.
