What does “subject to contract” mean in conveyancing?
“Subject to contract” is one of the most widely used phrases in UK property transactions — and one of the most misunderstood. When a seller accepts your offer, the property is marked “sold subject to contract,” and it can feel as though the deal is done. It is not. Subject to contract conveyancing means precisely what it says: the agreement exists, but it is not yet a contract, and it is not yet legally binding on either party.
That distinction matters enormously. Understanding exactly where you stand during the subject to contract period — and how you reach the point where you are genuinely protected — is essential knowledge for anyone buying or selling a property in England or Wales. The exchange of contracts is the legal milestone that transforms an informal acceptance into a binding subject to contract conveyancing commitment. Everything before that point carries both opportunity and risk in equal measure.
Subject to contract: the plain English explanation
When a property is described as “sold subject to contract” — often abbreviated to SSTC or STC — it means the seller has accepted a buyer’s offer, but the legal documentation has not yet been completed and no formal contract exists between the parties. The sale is agreed in principle but not in law.
This is the standard position in England and Wales from the moment an offer is accepted until the exchange of contracts takes place. During this window — which typically lasts between six and twelve weeks, though it can be shorter or longer — both the buyer and the seller are free to withdraw. There are no legal penalties for pulling out at this stage, though there will be practical costs: survey fees, solicitors’ time, and search fees already spent will not be recoverable if the deal falls through.
It is worth being clear about what “subject to contract conveyancing” does not mean. It does not mean the seller has stopped marketing the property. It does not mean the agreed price is fixed. It does not mean either party has made a commitment they are legally required to honour. An accepted offer in England and Wales is, at its core, a statement of intent — not a contract. The transformation from informal acceptance to legal obligation happens only at exchange.
What happens during the sold subject to contract period?
The period between offer acceptance and exchange of contracts is when the substantive legal and financial work of the transaction takes place. It is busy, it is consequential, and it is the stage where most problems surface.
Instructing solicitors and preparing the contract pack
Both buyer and seller instruct their respective solicitors immediately after an offer is accepted. On the seller’s side, the solicitor prepares the contract pack — including the title documents, property information forms, and any relevant supporting paperwork. For leasehold properties, this also includes the management information pack. On the buyer’s side, the solicitor reviews the draft contract, raises enquiries with the seller’s solicitor, and begins ordering the conveyancing searches.
Understanding what happens at each stage of this process helps both buyers and sellers move through it with confidence. Our detailed guide to the stages of the conveyancing process explains each step from offer acceptance through to completion in plain English.
Conveyancing searches and enquiries
While the exchange of contracts property milestone is still weeks away, the buyer’s solicitor is running searches — local authority, drainage and water, environmental — and raising enquiries based on the title documents and search results. These enquiries are the mechanism through which the buyer’s solicitor identifies anything that could affect the value or use of the property, and they must be resolved to the buyer’s satisfaction before exchange can be recommended.
Survey and mortgage
The sold subject to contract period is also when the buyer arranges a survey and progresses their mortgage application. If the survey reveals a significant structural issue, the buyer may use that as grounds to renegotiate the agreed price or, in serious cases, to withdraw entirely. The lender’s valuation will need to support the agreed price before a formal mortgage offer is issued. Until that mortgage offer is in place, the subject to contract conveyancing process cannot reach exchange.
Negotiating contract terms
The agreed price is the headline figure, but the contract itself contains more detail than that. Completion dates, what fixtures and fittings are included, and any special conditions the parties have agreed all need to be reflected in the draft contract and accepted by both sides. The subject to contract period is when these points are negotiated and documented, usually through correspondence between the two sets of solicitors.
The risks during the subject to contract conveyancing period
Because neither party is legally bound during the subject to contract period, both are exposed to risks that can derail the transaction entirely. These risks are real and reasonably common — according to published data, approximately one in four to one in three sales that reach the sold subject to contract stage ultimately fall through before exchange.
Gazumping
Gazumping occurs when a seller accepts a higher offer from a new buyer after already agreeing a sale with the original buyer. Because the sold subject to contract agreement is not legally binding, the seller is entitled to do this. Estate agents in England and Wales are legally required to pass on any offers they receive to the seller unless specifically instructed otherwise. For buyers, the risk of being gazumped is a real feature of the pre-exchange period, and it does not diminish simply because the legal process is already underway.
Gazumping is one of the most frustrating outcomes in residential property — particularly when it happens late in the subject to contract conveyancing period, after surveys, searches, and legal fees have already been incurred. Our guide to when conveyancing goes wrong covers the most common causes of failed transactions and what steps can be taken to reduce the risk.
Gazundering
Gazundering is the reverse problem — and it happens to sellers. This is where a buyer reduces their offered price shortly before exchange, often using survey findings or changed market conditions as justification. The seller is then faced with a choice between accepting the lower figure or starting the marketing process again. Because subject to contract conveyancing imposes no obligation on the buyer to proceed at the originally agreed price, gazundering is legal, even if it is widely considered sharp practice.
Chain collapse
Many property transactions in England and Wales are part of a chain, where a buyer is also a seller, and their purchase depends on their sale completing simultaneously. If any party in the chain withdraws during the sold subject to contract period — for any reason — every transaction above and below them in the chain is affected. An exchange of contracts property milestone cannot be reached by anyone in a chain until all parties in it are ready to exchange simultaneously. This dependency is the single biggest source of delay and failure in UK residential conveyancing.
Mortgage or survey issues
A buyer who loses their mortgage offer — because the lender’s valuation did not support the agreed price, or because their financial circumstances changed during the conveyancing period — may be unable to proceed. Similarly, a survey that reveals significant structural problems may lead a buyer to withdraw or seek a price reduction that the seller is unwilling to accept. Either outcome terminates the sold subject to contract arrangement without legal consequence to either party.

In property transactions, “subject to contract” means any agreement is not legally binding until contracts are exchanged. Get expert guidance to avoid mistakes before committing.
Exchange of contracts: when the agreement becomes legally binding
The exchange of contracts property transaction milestone is the point at which “subject to contract” ends and legal obligation begins. Exchange is the moment when both sets of solicitors confirm that signed contracts have been released, the deposit is paid by the buyer to the seller’s solicitor, and a fixed completion date is agreed. From that point, neither party can withdraw without serious financial consequences.
If a buyer pulls out after exchange, they forfeit their deposit — typically 10% of the purchase price. If a seller pulls out after exchange, they may be sued for damages, forced to complete, or required to pay the buyer’s wasted costs. The transformation from moral commitment to legal obligation at exchange is total and immediate.
The period between exchange and completion — during which final preparations for moving are made — is typically one to four weeks, though it can be simultaneous (exchange and complete on the same day) or longer if both parties agree. Our guide to how a completion date is chosen explains the factors that affect this timeline and what to consider when agreeing the date.
How to protect yourself during the sold subject to contract period
Given that the sold subject to contract period offers no legal protection, the most effective way to manage the risk is to move quickly, stay engaged, and take practical steps to reduce the window of exposure.
- Instruct your solicitor immediately after the offer is accepted — delays in instruction extend the subject to contract period and increase the risk of the deal falling through
- Arrange your survey promptly — a buyer who takes weeks to organise a survey signals uncertainty to the seller and increases the likelihood of an alternative offer being entertained
- Progress your mortgage application in parallel with the legal work — a formal mortgage offer in place removes one of the most common reasons for late withdrawal
- Respond quickly to your solicitor’s requests for information and documents — delays from your end slow the whole process down and extend the vulnerable period
- Ask the seller, through the estate agent, to take the property off the market — sellers are not obliged to do this, but many will if asked in the right way, particularly if the buyer demonstrates their own readiness to proceed
Exclusivity agreements
An exclusivity agreement — sometimes called a reservation agreement — is a legal document that commits the seller not to accept other offers for a defined period (typically four to eight weeks) in exchange for a reservation fee from the buyer. It does not make the underlying sale binding in the way that exchange of contracts does, but it does create legal obligations around the exclusive period and provides some financial deterrent against the seller accepting a competing offer. Exclusivity agreements are not standard practice in UK residential conveyancing but are available and can be negotiated in situations where the buyer’s exposure is particularly high.
Subject to contract in Scotland: an important difference
The subject to contract conveyancing rules described in this article apply to England and Wales. Scotland operates under a fundamentally different system. In Scotland, when a buyer’s offer is accepted and solicitors on both sides have concluded the exchange of formal letters known as “missives,” the contract becomes legally binding — there is no equivalent subject to contract period during which either party can withdraw without consequence. Gazumping is effectively impossible under the Scottish system because legal commitment occurs earlier in the process.
If you are buying or selling property in Scotland, the legal process is distinct and requires Scottish-qualified solicitors. The information in this guide relates solely to transactions in England and Wales.
Getting the right support from offer to exchange
The subject to contract conveyancing period is where the legal work is done — and where most transactions either succeed or fail. Having a solicitor who moves efficiently, communicates clearly, and identifies problems early makes a direct difference to whether your sold subject to contract status converts into a completed exchange of contracts. Our residential conveyancing team supports buyers and sellers throughout England and Wales, handling the legal work from instruction to completion with regular, proactive updates so you always know where your transaction stands.
If you have a question about a property transaction at any stage — whether you are preparing to make an offer, already in the sold subject to contract period, or approaching exchange — get in touch with our team for a straightforward conversation about where you stand and what your next steps should be.
