The average time to complete a property sale in England and Wales currently sits at around 120 days, and failed transactions cost the economy an estimated £1.5 billion each year. That is a staggering amount of wasted time, money, and stress for everyone involved. What this tells me, after years of watching the property market, is that the system has been quietly broken for a long time, and the contract you sign is often where the cracks show most.
I have seen buyers and sellers alike assume the contract is just a formality — something the solicitor handles while they focus on packing boxes. That assumption is expensive. The government has now described its proposed overhaul as the “biggest shake‑up to the home buying system,” and a major part of that involves making the contract stage far more transparent and binding earlier in the process. If you are planning to buy or sell in the next couple of years, understanding what is actually in that document — and what is about to change — is no longer optional. Here is what you actually need to know.
One practical step you can take right now is to get an early, independent review of your situation. If you are unsure where to start, speaking with a property lawyer before you even put in an offer can save you from signing something you do not fully understand. I would also recommend reading our guide on avoiding common home-buying regrets to see where other people have tripped up.
What a Property Sale Contract Actually Covers
The most important thing to understand is that the contract is not just about the price. It sets out the legal obligations of both parties, the property’s title, any rights of way, restrictions, and what happens if something goes wrong before completion. The updated TA6 Property Information Form — the 6th edition — becomes compulsory from 30 March 2026, and it demands far more detail from sellers than ever before. If you are selling, you need to be ready to answer questions about building safety, planning permissions, and even whether there have been any disputes with neighbours.
What I tend to notice is that most people focus on the survey and the mortgage offer, but the contract is where the legal risk lives. A poorly reviewed contract can leave you responsible for issues you never knew existed. My first move would always be to read the special conditions — those are the clauses your solicitor adds that are specific to your sale. They often contain the most important protections or, if you are not careful, the most significant pitfalls.

Why the 2026 Reforms Matter for Your Contract Review
The government’s proposals are not just background noise — they will directly change what you see in your contract. One of the most significant changes is the move toward binding contracts at an earlier stage. Under the current system, either party can pull out for almost any reason up to exchange, which is why fall-throughs are so common. The new system would allow buyers and sellers to enter into a conditional contract carrying a financial penalty for breach, including withdrawing from the transaction. That means if you change your mind after signing, you could lose real money.
Consider this scenario: you are a first-time buyer who finds a flat you love. Under the current rules, you can spend weeks on surveys and solicitor fees, then walk away if the survey reveals a problem. Under the proposed reforms, you would have to provide more information upfront, and if you signed an early binding contract and then pulled out without a valid reason, you could face a penalty. The trade-off is that sellers would also be locked in, which should reduce gazumping. The government estimates this could save first-time buyers an average of £710 and shorten the average transaction time by around four weeks.
Another change that will affect your contract review is the requirement for sellers and estate agents to disclose material information at the point of listing. This includes tenure, council tax band, EPC rating, title information, building safety data, planning consents, and chain status. In practice, this means the contract you eventually sign should have fewer surprises, because the key facts will already be on the table. But it also means you need to check that the information provided at listing matches what ends up in the contract — discrepancies can be a red flag.
I have seen cases where a seller’s omission — like an unapproved extension — only came to light during the contract review, causing the whole deal to collapse. The reforms should make that less likely, but they will not eliminate the need for a careful read. If you are a buyer, you might also want to look at our tips on understanding historical price trends to see how market conditions affect your negotiating position.
Where People Go Wrong When Reviewing a Property Contract
Most mistakes happen not because people are careless, but because they do not know what to look for. Here are the most common errors I see, backed by what the research tells us.
Overlooking the Special Conditions
The standard conditions of sale are fairly uniform, but the special conditions are where your solicitor inserts clauses unique to your transaction. These might cover everything from who pays for a specific repair to what happens if the completion date slips. A survey of conveyancing solicitors found that 70% believe digitisation will change their role, but a third do not feel ready for it. That lack of readiness can mean special conditions are not drafted as tightly as they should be. Always ask your solicitor to explain every special condition in plain English before you sign.
Ignoring the Property Information Form
The TA6 form is where the seller discloses everything from boundary disputes to whether the property has had Japanese knotweed. The 6th edition, coming in March 2026, will require even more detail. The mistake people make is treating this form as a box-ticking exercise. If the seller has answered “not known” to a question about planning permissions, that is a red flag. You need to follow up. The Law Society’s own response to the consultation noted that material information is not a silver bullet — it only works if buyers actually use it.
Not Checking the Title Plan Against the Property
The title plan shows the legal boundary of the property, but it does not always match what you see on the ground. Fences, hedges, and driveways can be in the wrong place. I have seen buyers discover after completion that their “garden” is actually a strip of land they do not own. The proposed digital property logbooks should help with this, but for now, you need to physically compare the title plan to the property. If something looks off, ask your solicitor to raise a query before exchange.
Assuming the Deposit Is Protected Automatically
If you are buying a leasehold property, the deposit rules can be different. In some cases, the deposit is held by the seller’s solicitor, not a protected scheme. If the seller’s firm runs into financial trouble, you could lose your money. The reforms include a public register of conveyancers and estate agents, which should make it easier to check who you are dealing with, but you should still confirm in writing how your deposit will be held and whether it is insured.

How to Review a Property Sale Contract Properly
You do not need to become a legal expert, but you do need a system. Here is the process I recommend, based on what the research and the upcoming changes tell us.
Get a Conveyancer Involved Before You Offer
The single best thing you can do is instruct a conveyancer before you make an offer. The Law Society’s survey found that around three in four (74%) members would be willing to be instructed by a seller to prepare for sale before a buyer is found. That same logic applies to buyers. If your solicitor sees the contract draft early, they can flag issues before you are emotionally and financially committed. This is especially important given that the number of conveyancers and solicitors in the sector has fallen sharply since 2021, meaning workloads per firm are increasing and turnaround times are under pressure. Getting in early gives you a slot in their schedule.
- 1Instruct a conveyancer before you offerGet them to review the draft contract and TA6 form as soon as they are available. Early instruction gives you time to raise queries before you are committed.
- 2Cross-check the property informationCompare the seller’s disclosed information — tenure, council tax, EPC, planning consents — against the contract and your own survey. Any mismatch needs an explanation.
- 3Read every special condition aloudAsk your solicitor to walk you through each one. If a condition seems vague or one-sided, request a revision. Do not assume standard wording is fair.
- 4Confirm deposit protection in writingAsk your solicitor to confirm how the deposit will be held and whether it is covered by insurance or a protected scheme. Get this in writing before you transfer any money.
What to Do About the New Binding Contract Proposals
The government is consulting on introducing binding contracts at an earlier stage, with financial penalties for breach. If this becomes law, you will need to be even more careful about what you sign early in the process. The key is to ensure you have all the information you need — survey results, search results, and finance in principle — before you enter into any binding agreement. The Law Society has emphasised that early binding contracts are only workable as part of a reformed system where buyers have the information they need before entering a contract. Do not let yourself be rushed into signing something binding before you have done your homework.
Digital Logbooks and What They Mean for You
One of the less talked-about changes is the introduction of digital property logbooks. These will standardise how property data is stored and shared, reducing the need for repeated searches and ID checks. The government could support wider adoption by setting requirements for new builds and on completion of the sale. For you, this means fewer forms to fill in and faster turnaround times, but it also means you need to ensure the data in your logbook is accurate. If you are selling, check that your logbook reflects the correct planning permissions and building safety data before it is shared with potential buyers.
