Exchange of Contracts: A Guide for Buyers and Sellers

Buying or selling a property is a major financial commitment, and one of the most important stages in the process is exchange of contracts. But what does exchange of contracts actually mean, and why is it so important?

In this guide, we explain what happens when contracts are exchanged, when a property purchase becomes legally binding, what you need to do before exchange, and what happens after contracts have been exchanged.

What is exchange of contracts?

Exchange of contracts is the point at which a property purchase or sale becomes legally binding in England and Wales.

Before contracts are exchanged, either the buyer or seller can generally withdraw from the transaction without being legally bound to complete the purchase or sale. Once contracts have been exchanged, however, both parties are legally committed to the transaction.

The contracts are formally exchanged between the buyer’s solicitor or conveyancer and the seller’s solicitor or conveyancer. This is usually done by telephone, electronically or through another agreed process between the legal representatives.

The exchange of contracts is therefore a significant milestone in the conveyancing process.

Is exchange of contracts legally binding?

Yes. Exchange of contracts makes the agreement to buy or sell the property legally binding, subject to the terms of the contract.

The contract will normally set out important details, including:

• The agreed purchase price

• The property being bought or sold

• The agreed completion date

• Any relevant conditions or provisions

• The obligations of the buyer and seller

Once contracts have been exchanged, pulling out of the transaction can have serious financial and legal consequences.

For example, if a buyer fails to complete after exchange, they may lose their deposit and could potentially face further financial consequences depending on the circumstances and terms of the contract.

What is the difference between exchange and completion?

Exchange of contracts and completion are two separate stages.

Exchange is when the transaction becomes legally binding.

Completion is when the purchase is finalised. On completion, the buyer’s funds are transferred to the seller’s solicitor, ownership of the property passes to the buyer, and the buyer can normally collect the keys.

For example, contracts could be exchanged on a Monday with completion taking place on Friday. The parties are legally committed from exchange, but the actual transfer of the property takes place at completion.

What happens before exchange of contracts?

There are several important steps that usually need to be completed before contracts can be exchanged.

These can include:

1. Property searches

The buyer’s conveyancer will usually carry out searches relating to the property. Depending on the property and location, these may include local authority, drainage and water, and environmental searches.

2. Property survey

A buyer may arrange a survey to assess the condition of the property. A survey can identify issues that may affect the buyer’s decision to proceed or influence negotiations.

3. Mortgage arrangements

If the purchase is being funded with a mortgage, the buyer will normally need to have their mortgage arrangements sufficiently advanced before exchange.

4. Legal enquiries

The buyer’s conveyancer will raise enquiries with the seller’s solicitor about the property and the information supplied during the transaction.

5. Contract review

The conveyancers will review the contract and make sure the relevant legal matters have been dealt with before the buyer is committed to the purchase.

6. Agreeing a completion date

The buyer and seller will normally agree the completion date before contracts are exchanged.

Once the necessary work has been completed and both parties are ready to proceed, the conveyancers can arrange exchange.

How does exchange of contracts work?

The exchange process is usually handled by the solicitors or conveyancers acting for the buyer and seller.

They confirm that both parties have signed the necessary contracts and have authority to exchange. They then formally exchange the contracts and agree the completion arrangements.

After exchange, the buyer and seller are informed that contracts have been exchanged and that the transaction is legally binding.

The exact procedure can vary depending on the circumstances and the conveyancers involved.

Can you exchange contracts on the same day as completion?

Yes, it is possible to exchange and complete on the same day, although this is not always the preferred arrangement.

Where exchange and completion happen on different days, there is a period between the two stages during which the parties know the transaction is legally binding but completion has not yet taken place.

Same-day exchange and completion can sometimes be used where circumstances require it, but it can involve additional practical considerations and less certainty for everyone involved.

What happens after exchange of contracts?

Once contracts have been exchanged, the transaction moves towards completion.

The buyer will normally make final preparations for the move, while the conveyancers will deal with the remaining legal and financial arrangements needed for completion.

On the agreed completion date:

1. The buyer’s funds are transferred to the seller’s solicitor.

2. The seller’s solicitor confirms receipt of the money.

3. Completion takes place.

4. The seller moves out if they have not already done so.

5. The buyer can usually collect the keys.

6. The legal work required after completion is dealt with by the conveyancers.

Can a buyer pull out after exchange?

Generally, you should not assume that you can simply withdraw after exchanging contracts.

Exchange creates a legally binding commitment. If a buyer fails to complete, there can be significant consequences, which may include losing their deposit and being liable for certain losses.

The position can depend on the circumstances and the terms of the contract, so anyone considering withdrawing after exchange should obtain legal advice immediately.

Can a seller pull out after exchange?

The same principle applies to sellers. Once contracts have been exchanged, the seller is legally committed to the transaction.

Failing to complete can potentially result in legal action and financial consequences.

This is one of the key reasons why buyers and sellers should make sure they are completely ready to proceed before authorising their solicitor or conveyancer to exchange contracts.

When should you exchange contracts?

There is no single date that is right for every property transaction.

Contracts should generally only be exchanged once the buyer and seller are ready and the necessary legal, financial and practical matters have been dealt with.

Your solicitor or conveyancer should advise you when they consider you ready to exchange.

If you are buying with a mortgage, it is particularly important to make sure your financing arrangements are in place before committing yourself to the purchase.

What should you do before exchange of contracts?

Before exchange, buyers should make sure they are comfortable with the property and the transaction.

You should consider whether:

• Your mortgage arrangements are in place.

• Your searches have been completed and reviewed.

• You have received and considered the relevant legal information.

• Any important enquiries have been answered.

• You are satisfied with the results of your survey.

• You know what fixtures and fittings are included.

• The completion date has been agreed.

• You have the money required for the purchase and associated costs.

• You understand the legal commitment you are about to make.

If you have any concerns, raise them with your conveyancer before contracts are exchanged.

What happens to the deposit on exchange?

The buyer will normally pay a deposit as part of the exchange process. The amount can vary depending on the transaction and the terms agreed between the parties.

It is important to understand that the deposit is not necessarily the same thing as the buyer’s entire contribution towards the purchase price.

Your conveyancer should explain exactly how much money is required and how it will be dealt with as part of the transaction.

Why is exchange of contracts so important?

Before exchange, a property transaction can still fall through. This can be frustrating for buyers and sellers who may have already spent money on surveys, searches, mortgage arrangements and legal fees.

Exchange provides certainty because it creates a legally binding commitment to complete the transaction.

For buyers, it means they can normally make their final moving arrangements knowing that the purchase is legally committed. For sellers, it provides certainty that the buyer is contractually obliged to proceed, subject to the terms of the contract.

Final thoughts: exchange of contracts explained

Exchange of contracts is one of the most important stages when buying or selling a property. It is the point at which the transaction becomes legally binding, meaning both buyer and seller are committed to completing in accordance with the contract.

Before exchange, make sure you have discussed any concerns with your solicitor or conveyancer and understand the financial and legal commitment you are making.

Once contracts have been exchanged, the transaction can move towards completion and, for the buyer, the long-awaited day when the keys are handed over.
