Your offer was accepted, and the estate agent mentioned a memorandum of sale. What is this document, and why does it matter?
In my years advising property clients, I have seen confusion about this stage cause unnecessary anxiety. A memorandum of sale is a written record that confirms the agreed deal between buyer and seller.
It includes names, the price, and solicitor details. The estate agent prepares it to start the conveyancing process.
A memorandum of sale is not legally binding, and either party can withdraw before contracts are exchanged. This guide explains what it is, who prepares it, what happens next, and how long the process takes.
What Does a Memorandum of Sale Mean?
A memorandum of sale, also called a memo of sale or sale memorandum, is a short written record of an agreed property deal. It confirms who is buying, who is selling, and at what price.
The estate agent prepares the document and sends it to both parties and their solicitors.
It records the transaction details so everyone involved has the same information. This helps the legal side of the sale begin without delay.
Both parties receive a copy early in the process. It sets the foundation for everything that follows. Without it, the conveyancing process cannot officially begin.
When Is a Memorandum of Sale Issued?

The timing of a memorandum of sale is very specific; it follows a clear sequence in every property transaction.
After the Seller Accepts an Offer
Buying a property starts with negotiation. The buyer makes an offer. The seller either accepts, rejects, or counters it. Once the seller formally agrees to the buyer’s offer, the estate agent steps in.
They confirm the acceptance in writing and prepare thememorandum of sale straight away.
Before Contracts Are Exchanged
The memo of sale appears very early in the legal process. It is issued before any contracts are signed or exchanged. Its main job is to notify both solicitors that the transaction has officially started.
This allows conveyancers to begin their legal checks, searches, and inquiries without delay.
Why the Timing Matters
Getting the memorandum of sale out quickly helps all parties move fast. It allows mortgage applications and property surveys to begin.
In a property chain, any delay can slow things down for everyone involved. Early issuance also reduces the risk of confusion about what was agreed between the buyer and seller.
Who Issues the Memorandum of Sale?

In most property sales, one party takes the lead in preparing and sending the memorandum of sale, and the process follows a clear pattern.
Estate Agent Responsibilities
The estate agent is responsible for preparing the memorandum of sale. They gather key details from both the buyer and the seller.
This includes names, addresses, solicitor details, and the agreed price. Before sending it out, they confirm all information with both parties to make sure everything is accurate.
Who Receives the Document
Once prepared, the memo of sale goes to several parties. These include the buyer, the seller, the buyer’s solicitor or conveyancer, and the seller’s solicitor or conveyancer.
In some cases, the buyer’s mortgage broker also receives a copy to begin the lending process.
Private Sales Without Estate Agents
Not every property sale involves an estate agent. In private sales, the solicitor often prepares the document.
The buyer and seller may confirm details directly with each other. In either case, making sure the document is accurate is very important. Errors at this stage can cause problems later.
What Is Included in a Memorandum of Sale?
A memorandum of sale covers all the essential details of the agreed property deal. These details give solicitors everything they need to begin the conveyancing work.
| CATEGORY | WHAT’S INCLUDED |
|---|---|
| Property Details | Full property address, type, and tenure status (freehold or leasehold) Land Registry references where applicable |
| Buyer and Seller Information | Full names and contact details of both parties Solicitor or conveyancer details for both sides |
| Financial and Deal Details | Agreed on purchase price and deposit expectations Mortgage lender details or cash buyer confirmation Any negotiated price terms |
| Transaction Details | Proposed completion timeline and chain details Fixtures and fittings included in the sale Any special conditions agreed by both parties |
Note: Always photograph fixtures you expect to stay with the property. Disputes over missing items are common, and photos taken before exchange provide clear evidence if the seller removes agreed items.
Is a Memorandum of Sale Legally Binding?
A memorandum of sale isn’t legally binding, but it serves as an important step in the process.
It confirms the agreed deal and starts the conveyancing process, but either party can still walk away without legal consequences.
The sale only becomes legally binding at the exchange of contracts, when both parties sign formal agreements, and the buyer pays the deposit.
Memorandum of Sale vs Contract of Sale
Both documents are part of the property buying process, but they serve very different purposes. Here is a clear breakdown.
| Feature | Memorandum of Sale | Contract of Sale |
|---|---|---|
| What it is | A summary of the agreed deal | A formal legal contract |
| Main purpose | Used to start conveyancing | Defines legal obligations of both parties |
| Who prepares it | Estate agent or solicitor | Solicitor or conveyancer |
| Legally binding | No | Yes |
| Can parties walk away | Yes, without legal consequences | No, serious financial penalties apply |
| When it is issued | Right after the offer is accepted | Prepared later by solicitors |
| Where it sits in the process | Early stage | Later stage |
| Legal commitment | No commitment | Exchange marks a full legal commitment |
What Happens After a Memorandum of Sale Is Issued?
Once the memorandum of sale is sent out, the property transaction moves quickly. The following stages typically unfold in this order.
Conveyancing Process Begins
As soon as solicitors receive the memo of sale, they open the legal file. They carry out identity verification checks on both parties.
Anti-money laundering checks are also completed at this stage. This ensures the transaction meets all legal requirements before anything else moves forward.
Property Searches and Checks
The buyer’s solicitor orders a series of searches. These include local authority searches, environmental searches, and water and drainage checks.
The solicitor also carries out title verification to confirm that the seller legally owns the property and has the right to sell it.
Mortgage and Survey Steps
The buyer works on finalizing their mortgage application with their lender. The lender then arranges a valuation of the property.
The buyer may also book an independent property survey to check the condition of the building before committing further.
Contract Preparation
The seller’s solicitor drafts the contract of sale. The buyer’s solicitor carefully reviews all the terms. Any questions or concerns are raised as formal inquiries.
Both sides work through these until all points are agreed and the contract is ready for exchange.
Exchange and Completion
Once all checks and inquiries are resolved, both parties reach a final agreement. Contracts are exchanged and become legally binding.
A completion date is then scheduled. On completion day, the remaining funds are transferred, and ownership of the property officially changes hands.
How Long Does It Take From Memorandum of Sale to Completion?
The time between a memorandum of sale and completion typically ranges from 8 to 20 weeks in the UK. Straightforward sales usually complete in 8 to 12 weeks.
However, delays caused by mortgage approval, survey issues, legal inquiries, chain problems, or missing paperwork can push the timeline closer to 20 weeks or beyond.
Common Problems Buyers and Sellers Should Watch For
Thesale stage seems straightforward, but problems can occur. Some issues are easy to fix early; others can delay or end the transaction. Knowing what to watch helps protect your interests.
Errors in the Memorandum
The purchase price is listed incorrectly on the document. Wrong solicitor details for either party. Incorrect property address or tenure information.
Always check the document carefully before the conveyancing process begins.
Delays in Issuing the Document
Missing buyer details can hold up the process. Incomplete contact information causes communication gaps.
Estate agent processing delays can slow things down. Providing all required details upfront helps avoid unnecessary waiting.
Gazumping Risk
A seller may accept a higher offer from another buyer after the memo is issued. This can happen at any point before contracts are exchanged.
The memorandum of sale is not legally binding, so buyers have no legal protection. Buyers remain vulnerable until the exchange of contracts.
In advising property clients, I’ve seen gazumping devastate buyers who thought their purchase was secure, with emotional and financial costs being significant. Some buyers move quickly to exchange to lower this risk.
Sale Falling Through
Mortgage refusal can end the deal at any stage. A poor survey result may lead to renegotiations or withdrawal.
The buyer’s withdrawal is always a possibility before the exchange. A chain collapse can bring the entire transaction to a halt.
Property Chain Complications
A property chain forms when your buyer needs to sell their own property before they can buy yours. If your buyer’s buyer withdraws, the entire chain can collapse.
This leaves you without a buyer and potentially unable to proceed with your own onward purchase.
For first-time buyers looking to avoid chain risks, purchasing a new-build property can offer greater certainty.
New build homes aren’t part of existing chains, involving fewer parties and offering clearer completion. Many developers provide schemes like Part Exchange or Assured Sale to assist buyers needing to sell their current property.
Final Thoughts
A memorandum of sale records the agreed deal but does not finalize it. The binding commitment only happens at the exchange of contracts.
Review the document carefully for errors. Check names, prices, and solicitor details before the process begins.
Good communication between your estate agent and solicitor keeps things moving smoothly. Got questions? Speak to your solicitor early. It makes all the difference.
