How to Prepare for Exchange Day as a Seller
Exchange of contracts is the moment your property sale becomes legally binding. This checklist covers every document, task, and practical step you need to have ready before your solicitor picks up the phone to exchange.
What you need to know
Exchange day is when your sale becomes legally binding. Before your solicitor can exchange, you need signed contracts, a signed TR1 transfer deed, an agreed completion date, confirmed buildings insurance, and all outstanding enquiries resolved. Thorough preparation prevents last-minute delays that put the entire transaction at risk.
- Sign and return your contract and TR1 transfer deed to your solicitor at least a few days before the planned exchange date.
- Confirm the completion date works for you, the buyer, and everyone else in the chain before exchange locks it in.
- Ensure your buildings insurance remains active until completion day — you are responsible for the property until ownership transfers.
- Start practical preparations such as booking removals, setting up mail redirection, and notifying utility providers as soon as exchange is likely.

Check your sale readinessAfter weeks of conveyancing, enquiries, and waiting for searches, exchange day is the moment everything becomes real. Once your solicitor exchanges contracts with the buyer's solicitor, both parties are legally committed. The buyer has paid their deposit, a completion date is fixed, and pulling out would mean a breach of contract with serious financial consequences.
But exchange cannot happen until you, as the seller, have completed a specific set of tasks. Miss any of them and the exchange will be delayed — potentially by days or weeks. If you are in a chain, your delay holds up every other party too.
This guide provides a comprehensive checklist of everything you need to have ready before exchange day, explains what happens during the exchange itself, and covers the practical steps you should take in parallel. It applies to residential property sales in England and Wales under the Law Society's Conveyancing Protocol.

Pre-exchange legal checklist
These are the legal and administrative items that must be completed before your solicitor can exchange contracts. Every item on this list is essential — if any are missing, your solicitor will not be able to proceed.
| Task | Details | Status |
|---|---|---|
| Sign the final contract | Your solicitor will send you the engrossed (final) version of the sale contract for your signature. Check the sale price, completion date, and any special conditions before signing. Every person named on the title must sign. Return it to your solicitor promptly. | □ |
| Sign the TR1 transfer deed | The TR1 is the official HM Land Registry form that transfers ownership of the property. Your signature must be witnessed by an independent adult who is not a party to the sale. Your witness must add their full name, address, and signature. | □ |
| Confirm all enquiries are resolved | Check with your solicitor that every enquiry raised by the buyer's solicitor has been answered satisfactorily. Any outstanding enquiry can block exchange. If you have been asked to provide additional documentation, make sure it has been sent. | □ |
| Agree the completion date | The completion date is written into the contract at exchange and cannot be changed unilaterally afterwards. Make sure the date works for you, your buyer, and everyone in the chain. Factor in time for removals and any onward purchase. | □ |
| Confirm mortgage redemption statement | Your solicitor will need an up-to-date redemption statement from your mortgage lender, valid for the agreed completion date. Request this at least two weeks before the planned exchange to allow for processing time. Some lenders take 10 to 14 working days. | □ |
| Check buildings insurance is active | You remain responsible for insuring the property until completion day. Confirm that your buildings insurance policy covers the property right through to the completion date. If your policy is due for renewal, extend it. | □ |
| Review the completion statement | Your solicitor will prepare a completion statement showing the sale price, mortgage redemption figure, estate agent fees, legal fees, and the net amount you will receive. Review it carefully and query anything that does not match your expectations. | □ |
| Confirm any special conditions are met | If the contract includes special conditions — for example, remedial work to be completed before completion, or indemnity insurance to be put in place — make sure these have been satisfied and evidenced before exchange. | □ |

Understanding the exchange process
Exchange of contracts is a formal legal step that takes place by telephone between the two solicitors. The actual call typically lasts only a few minutes, but significant preparation goes into making it possible. Here is what happens.
How solicitors exchange contracts
Solicitors exchange contracts using one of three formulas agreed by the Law Society. In most residential transactions, they use Formula B or Formula C:
- Formula A: Both solicitors hold their client's signed contract. They exchange by post, with each solicitor sending the contract they hold to the other. Rarely used in practice because of the postal delay.
- Formula B: One solicitor (usually the buyer's) holds both signed contracts. Exchange happens by telephone, with the buyer's solicitor undertaking to send the seller's signed copy by post the same day. This is the most common formula for standard transactions.
- Formula C: Used in chain transactions. Each solicitor in the chain exchanges with the next in a coordinated sequence of telephone calls, so that all transactions in the chain exchange simultaneously. This prevents one party from being committed while another is not.
Once the telephone exchange is confirmed, the buyer's solicitor sends the deposit (typically 10% of the purchase price) to your solicitor. The sale is now legally binding, and the completion date is fixed.
What time does exchange happen?
Exchanges most commonly happen between 10am and 4pm on a working day. In a chain, all exchanges must be coordinated, which means the process can take several hours as each solicitor in the chain confirms they are ready. Your solicitor will call you to confirm once exchange has taken place. In practice, it is not uncommon for chain exchanges to be confirmed in the late afternoon.
Practical preparations before exchange
While the legal tasks above must be completed before exchange can happen, there are also a number of practical steps you should start working on in advance. These are not legal requirements for exchange itself, but they ensure you are ready for the period between exchange and completion, which is typically one to two weeks.
| Task | When to start | Status |
|---|---|---|
| Get removal quotes and make a provisional booking | 2–3 weeks before exchange | □ |
| Set up Royal Mail redirection to your new address | 1–2 weeks before exchange | □ |
| Notify utility providers (gas, electricity, water, broadband) | 1–2 weeks before exchange | □ |
| Notify council tax of your moving date | 1–2 weeks before exchange | □ |
| Begin packing non-essential items | 2 weeks before exchange | □ |
| Gather all keys (front, back, garage, shed, window locks, communal) | 1 week before exchange | □ |
| Collect instruction manuals, alarm codes, and appliance guides | 1 week before exchange | □ |
| Confirm key handover arrangements with the estate agent | A few days before exchange | □ |

The completion date: how to choose it wisely
The completion date is agreed before exchange and locked into the contract. Once exchanged, changing it requires the consent of both parties and, if there is a chain, every party in that chain. Choosing the right date matters more than many sellers realise.
Factors to consider
- Time to move: A gap of one to two weeks between exchange and completion is standard. This gives you time to confirm removal bookings, finish packing, and handle final logistics. If you need more time, discuss this with your solicitor before exchange.
- Day of the week: Friday is the most popular completion day because it gives the buyer a weekend to move in. However, if something goes wrong with the funds transfer on a Friday, it cannot be resolved until Monday. Completing on a Tuesday, Wednesday, or Thursday provides a buffer in case of banking delays.
- Chain alignment: If you are in a chain, the completion date must work for every party. Your solicitor and estate agent will coordinate with the other parties to find a date that suits everyone.
- Mortgage redemption validity: Your mortgage redemption statement is valid for a specific date. If completion is delayed beyond that date, your solicitor will need to request a new statement, which can take several days.
- Your onward purchase: If you are buying another property simultaneously, both transactions will typically complete on the same day. Make sure your solicitor handling the purchase is aligned with the sale timeline.
Common mistakes that delay exchange
Even when the conveyancing work is largely done, exchange can be held up by avoidable mistakes on the seller's side. These are the most common issues solicitors see.
- Not returning signed documents promptly. Your solicitor sends you the contract and TR1 for signing. If you take a week to return them, that is a week added to the timeline. Sign and return documents on the same day if possible, or within 48 hours at most.
- Failing to arrange a witness for the TR1. The TR1 transfer deed requires your signature to be witnessed by an independent adult. This catches some sellers off guard, especially if they are signing at home and do not have a suitable witness immediately available. Plan ahead.
- Not confirming the completion date in time. Your solicitor needs your agreement on the completion date before they can exchange. If you are slow to respond or cannot decide, the exchange is held up. If you are in a chain, a completion date that does not work for one party means renegotiating with everyone.
- Letting buildings insurance lapse. If your buildings insurance expires between exchange and the planned completion date, your solicitor may not be willing to exchange until it is renewed. Check your policy dates well before exchange day.
- Outstanding enquiries you forgot about. You may have answered most enquiries weeks ago, but if there is one outstanding item — perhaps a missing certificate or an unclear answer that the buyer's solicitor has followed up on— exchange cannot happen until it is resolved. Ask your solicitor to confirm that nothing is outstanding.
- Not reading the completion statement. The completion statement sets out exactly how the sale proceeds will be distributed. If you do not review it before exchange and a figure is wrong, it will need to be corrected, which can hold things up. Read it carefully as soon as your solicitor sends it.
What to do on exchange day itself
Exchange day can feel anticlimactic for sellers because most of the work has already been done. Your solicitor handles the exchange call, and your main role is to be available and responsive. Here is what to expect.
Morning
Your solicitor will contact you to confirm that everything is in order and that they plan to exchange today. If you are in a chain, they may give you a time estimate based on when the other solicitors expect to be ready. Keep your phone charged and accessible.
During the exchange
The solicitors conduct the exchange by telephone. Your solicitor and the buyer's solicitor confirm the terms of the contract, the deposit amount, and the completion date. Once both solicitors are satisfied, the exchange is confirmed verbally. In a chain using Formula C, this process is repeated for each link in the chain.
After exchange is confirmed
Your solicitor will call or email you to confirm that exchange has taken place. At this point:
- The sale is legally binding. Neither party can pull out without facing financial penalties.
- The completion date is fixed. It is written into the contract and can only be changed by mutual agreement.
- The buyer has paid the deposit (typically 10%) to your solicitor.
- You can now confirm your removal booking and make any final arrangements for moving day.

Exchange in a chain: what you need to know
If you are part of a property chain, exchange is more complex because all transactions in the chain must exchange on the same day. This is coordinated using Law Society Formula C, where each solicitor in the chain exchanges with the next in a specific sequence.
As a seller in a chain, your key responsibilities are:
- Be ready when the chain is ready. Do not be the party holding things up. Have your signed contract and TR1 with your solicitor well in advance.
- Agree a completion date that works for everyone. In a chain, the completion date must suit every party. Be flexible where you can, within reason.
- Stay in contact. On the day of exchange, your solicitor may need to reach you quickly to confirm a detail or get your agreement on a minor point. Be available by phone throughout the day.
- If you are buying as well as selling, make sure your purchase solicitor is aligned with your sale solicitor. Both transactions need to exchange simultaneously.
Chain exchanges can take several hours to complete because every solicitor must confirm readiness before the exchange calls begin. It is normal for the process to extend into the late afternoon. For tips on managing the overall process, see our guide on how to speed up conveyancing as a seller.
After exchange: immediate next steps
Once exchange is confirmed, the countdown to completion begins. There are several things you should do straight away.
- Confirm your removal booking. If you made a provisional booking, call the removal company and confirm the date and time. If you have not yet booked, do so immediately— popular dates fill up quickly, especially Fridays.
- Finalise your Royal Mail redirection. If you have already applied, confirm the start date matches your completion date. If you have not yet applied, do so now via the Royal Mail website. Redirection starts from £36.99 for three months.
- Contact utility providers. Give your gas, electricity, water, and broadband providers the completion date as your final day at the address. You will provide final meter readings on completion day itself.
- Notify your council tax office. Tell your local council the date you are moving so they can close your account or adjust your bill.
- Start packing in earnest. With the completion date fixed, work backwards from that date to create a packing schedule. Pack room by room, starting with items you use least often.
- Keep your solicitor informed. If anything changes on your side — for example, an issue with your onward purchase — tell your solicitor immediately.

Buildings insurance: your obligations
One of the most commonly overlooked aspects of exchange preparation is buildings insurance. Under the Standard Conditions of Sale (6th Edition), the risk in the property passes to the buyer on exchange. However, in practice, many mortgage lenders require the buyer's buildings insurance to start from completion, not exchange. This means that between exchange and completion, the situation can be ambiguous.
The safest approach — and the one most solicitors recommend — is to maintain your own buildings insurance right through to completion day. If your policy is due to expire before the completion date, renew it or extend it. The cost of a few extra weeks of cover is negligible compared with the risk of an uninsured property being damaged before the sale completes.
How to handle exchange day nerves
Exchange day can be stressful, particularly if you have been waiting weeks for this moment. Here are some practical tips to help you stay calm and in control.
- Trust the preparation. If you have worked through the checklist in this guide, everything your solicitor needs is already in place. The exchange call itself is a formality at this point.
- Keep your phone on and charged. Your solicitor may need to reach you at short notice. Save their direct number so you recognise the call.
- Avoid making plans that take you out of contact. Exchange day is not the day for a long meeting or a trip to an area with poor mobile signal. Stay available until your solicitor confirms exchange is done.
- Expect delays if you are in a chain. Chain exchanges frequently take longer than anticipated. If your solicitor said exchange would happen by lunchtime and it has not, do not panic — it usually means another link in the chain is being finalised.
- Celebrate when it is confirmed. Exchange is the most significant milestone in the conveyancing process. Once it is done, the sale is committed and completion is just around the corner.
How Pine helps you reach exchange faster
The reason exchange takes so long for most sellers is that the preparation work — completing forms, gathering certificates, ordering searches — only starts after an offer is accepted. Pine reverses that process. By helping sellers complete their TA6 and TA10 forms, order property searches, and assemble a solicitor-ready legal pack before listing, Pine compresses the pre-exchange timeline significantly.
When an offer arrives, your solicitor can send the complete contract pack on day one. Enquiries are fewer because the forms are thoroughly completed. Searches are already done. The result is that prepared sellers using Pine reach exchange weeks faster than the average — meaning less time at risk of the buyer pulling out and a shorter wait before your sale is legally committed.

Frequently asked questions
What documents do I need to sign before exchange of contracts?
Before exchange, you must sign the final version of the sale contract and the TR1 transfer deed. The contract confirms the agreed sale price, completion date, and any special conditions. The TR1 is the official HM Land Registry form that transfers ownership to the buyer. Your signature on the TR1 must be witnessed by an independent adult who is not a party to the transaction. Your solicitor will send both documents to you for signing, usually a few days before the planned exchange date.
How far in advance should I prepare for exchange day?
You should begin preparing for exchange day at least two weeks before the target date. This gives you time to sign and return documents, confirm the completion date with all parties, arrange removals, set up mail redirection, notify utility providers, and resolve any last-minute issues. Some tasks, such as booking a removal company, should be done even earlier because popular dates fill up quickly.
Can exchange of contracts happen on the same day as completion?
Yes, simultaneous exchange and completion is possible and is most common in chain-free transactions. However, it carries additional risk because neither party is legally committed until the moment of exchange. If a problem arises on the morning of the planned date, the sale could still fall through. Most solicitors advise a gap of one to two weeks between exchange and completion to allow time for final preparations.
What happens if I am not ready for exchange day?
If you are not ready, exchange will be postponed. There is no legal penalty for delaying exchange because neither party is yet committed. However, repeated delays increase the risk of the buyer pulling out, their mortgage offer expiring, or searches going out of date. If you are part of a chain, your delay holds up every other transaction in the chain, which can cause significant frustration and even chain collapse.
Do I need to pay anything on exchange day?
As the seller, you do not pay a deposit on exchange day — it is the buyer who pays the deposit (typically 10% of the purchase price) to your solicitor. However, you should check with your solicitor whether any outstanding fees or disbursements are due before exchange. If you are also buying a property, you may need to provide a deposit for your own purchase on the same day.
What is the deposit and what happens to it after exchange?
The buyer’s deposit is typically 10% of the purchase price, paid to your solicitor on exchange. Your solicitor holds the deposit in their client account until completion day, at which point it forms part of the total purchase funds. If the buyer fails to complete after exchange, you may be entitled to keep the deposit as compensation. If you are in a chain, your solicitor may pass the deposit up the chain to fund your own purchase deposit.
Can the buyer pull out after exchange of contracts?
Pulling out after exchange is a breach of contract and carries serious financial consequences. If the buyer fails to complete, you can serve a notice to complete giving them 10 working days. If they still do not complete, you can rescind the contract, keep their deposit (usually 10% of the purchase price), and claim damages for any additional losses such as the cost of remarketing the property. In practice, buyers very rarely pull out after exchange.
How long is the gap between exchange and completion?
The gap between exchange and completion is typically one to two weeks, though it can be as short as the same day (simultaneous exchange and completion) or as long as several months in some circumstances. The completion date is agreed between the parties before exchange and is written into the contract. Most sellers prefer a gap of one to two weeks to allow time for final packing, removals booking, and practical preparations.
What happens if there is a problem with the chain on exchange day?
If one party in the chain is not ready to exchange, the entire chain is held up because all transactions must exchange simultaneously. Your solicitor and estate agent will work to identify the hold-up and resolve it. Common causes include a mortgage offer not yet being received, outstanding enquiries that have not been answered, or a party further up the chain who has not signed their contract. If the problem cannot be resolved quickly, exchange may be postponed by a few days or weeks.
Do I need buildings insurance until completion day?
Yes. As the seller, you remain responsible for insuring the property until completion day when ownership formally transfers to the buyer. Your buildings insurance policy must remain active and provide full cover right up to the completion date. If your policy lapses between exchange and completion and the property is damaged, you could be in breach of the contract and liable for significant costs. Check with your insurer well before exchange to confirm your cover end date.
