Exchange vs Completion Explained: Understanding Two Key Stages of the Conveyancing Process
If you're buying or selling a property, you've probably heard the terms exchange and completion used throughout the transaction.
Whilst these are two of the most important milestones in the conveyancing process, many buyers and sellers are unsure what each stage actually means and how they differ.
Understanding the distinction between exchange and completion can help you feel more informed, confident and prepared as your transaction progresses.
What Is Exchange of Contracts?
Exchange of contracts is the point at which the transaction becomes legally binding.
Prior to exchange, either party can generally withdraw from the transaction without legal consequence. Once contracts have been exchanged, however, both the buyer and seller are committed to proceeding with the sale and purchase.
At exchange:
The buyer and seller become legally bound by the contract.
A completion date is agreed.
The buyer's deposit is transferred (where applicable).
The transaction becomes legally enforceable.
This is often one of the most significant milestones in the conveyancing process, as it provides certainty for all parties involved.
What Happens Before Exchange?
Before contracts can be exchanged, your conveyancer must ensure that all legal and practical requirements have been satisfied.
This will usually include:
Reviewing the Legal Title
Your conveyancer will investigate the title to the property to ensure there are no issues that could affect your ownership or future use of the property.
Conducting Property Searches
Searches provide important information about the property and surrounding area, including matters such as planning permissions, drainage connections and environmental considerations.
Raising and Resolving Enquiries
Additional enquiries are often raised with the seller's conveyancer to clarify matters identified within the title documents, property information forms or search results.
Receiving the Mortgage Offer
If you are purchasing with the assistance of a mortgage, your formal mortgage offer will need to be received and reviewed.
Reporting to You
Once all investigations have been completed, your conveyancer will provide a detailed report explaining the legal aspects of the transaction and highlighting any matters you should be aware of before proceeding.
Signing Documents and Providing Funds
The necessary documents must be signed and any funds required prior to exchange, including the deposit, must be received.
Only once all parties are ready can contracts be exchanged
What Is Completion?
Completion is the day ownership of the property officially changes hands.
This is often referred to as "moving day" because it is when the buyer receives the keys and can take possession of the property.
On completion:
The purchase funds are transferred to the seller's conveyancer.
Legal ownership passes to the buyer.
The estate agent is authorised to release the keys.
The seller vacates the property.
The buyer can move into their new home.
For most clients, completion is the most exciting stage of the transaction as it marks the successful conclusion of the conveyancing process.
How Long Is There Between Exchange and Completion?
The period between exchange and completion can vary depending on the circumstances of the transaction.
Traditionally, there may be a gap of one to four weeks between the two stages. This allows buyers and sellers time to arrange removals, organise utilities, finalise packing and prepare for moving day.
However, some transactions exchange and complete on the same day.
Whilst simultaneous exchange and completion is possible, it can carry additional risks and is not always suitable, particularly where there is a property chain involved.
Your conveyancer will advise you on the most appropriate timescales for your particular transaction.
Why Are Exchange and Completion Separate?
Having a period between exchange and completion provides certainty and allows everyone involved to prepare for the move.
Once exchange has taken place, all parties know the transaction is legally committed and the completion date is fixed.
This can significantly reduce uncertainty and help ensure a smoother moving process.
A Simple Way to Remember the Difference
A useful way to remember the distinction is:
Exchange = The Legal Commitment
Completion = The Move
Exchange is when the transaction becomes legally binding.
Completion is when ownership changes hands and the keys are released.
