What Should a Property Sale Contract Include?

A property sale contract in England should clearly set out who is buying and selling, what property is being sold, the price, the deposit, the completion date, and any special terms affecting the deal. It must also meet the legal formalities for land contracts: it needs to be in writing, contain all agreed terms, and be signed by both parties.

For buyers and sellers, the contract is not just a formality. It is the document that turns a negotiated deal into a binding legal agreement once contracts are exchanged.

What a property sale contract is

In a residential conveyancing transaction, the sale contract is the agreement that records the full terms of the transfer of the property from seller to buyer. In England and Wales, residential sales commonly use the Law Society’s Standard Conditions of Sale, supplemented by bespoke clauses for the particular transaction. These standard conditions provide a reliable framework that most solicitors and conveyancers work with day in, day out, but they are almost always tailored to fit the specific deal.

The contract becomes legally binding at exchange of contracts, not when an offer is accepted in principle. That distinction catches many people out. An accepted offer gives you a moral commitment, but until exchange happens, either side can walk away without legal penalty. Exchange is the point of no return, and that’s why the drafting stage matters so much.

The legal minimum: what must be in it

For a contract for the sale of land to be valid under section 2 of the Law of Property (Miscellaneous Provisions) Act 1989, it must be:

• in writing;
• incorporate all the agreed terms; and
• signed by or on behalf of both parties.

That means side deals, missing clauses, or vague promises can create problems if they are not captured properly in the written contract. I’ve seen cases where a buyer assumed the garden shed was included because the seller mentioned it during a viewing, but the contract was silent on the point. Without written inclusion, that promise is effectively worthless. The lesson is simple: if it matters, it must appear in the contract.

Core clauses every property sale contract should include

1. Names of the parties

The contract should identify the seller and buyer clearly, including full legal names and, where relevant, all parties if there is more than one buyer or seller. This matters because joint parties are usually bound by the contract together. If you’re buying with a partner or friend, you’ll typically be jointly and severally liable, meaning each of you can be pursued for the full performance of the contract if something goes wrong. Getting the names right also avoids complications with the Land Registry later.

2. Full property description

The contract should describe the property precisely, including:

• the full address;
• the Land Registry title number;
• whether the property is freehold or leasehold; and
• any additional title if more than one title is being sold.

A precise description helps avoid disputes about what is actually included in the sale. I’ve dealt with disagreements over parking spaces, garden strips, and even loft conversions that weren’t properly reflected in the title plan. The contract should tie the property to the registered title so there’s no ambiguity.

3. Purchase price

The contract must state the agreed purchase price clearly. It should also make clear whether the price includes VAT, where that is relevant. While VAT rarely applies to residential property sales, it can crop up with new builds, commercial conversions, or the sale of part of a property. A clear figure avoids last-minute disputes about what the buyer is actually paying.

4. Deposit terms

The contract should explain the deposit amount, when it is paid, and what happens to it if the buyer fails to complete. In many residential transactions, the deposit is 10% of the purchase price, although this can be varied by agreement. The deposit is usually held by the seller’s solicitor as stakeholder, which means it cannot be released until completion. If the buyer defaults, the seller may be entitled to keep the deposit as compensation, but the exact consequences depend on the wording of the contract and the standard conditions.

5. Completion date

The completion date should be stated in the contract so both sides know exactly when the balance of the price must be paid and the transfer is completed. If the date is left open-ended, delay and uncertainty quickly follow. A fixed date allows everyone to plan removals, mortgage drawdowns, and the handover of keys. In a chain, a clear completion date is even more critical because one delay can ripple through multiple transactions.

6. Title and ownership details

The contract should reflect the seller’s legal ability to sell and identify the title being transferred. If the property is leasehold, the contract should also reflect the leasehold position, because the buyer is purchasing the leasehold interest rather than the freehold itself. This section often cross-refers to the official copies of the register and the title plan, which the buyer’s solicitor will have examined. Any restrictions on the title—such as a charge in favour of a lender—must be dealt with before or at completion.

7. Fixtures, fittings, and contents

The contract should deal with what is included in the sale, especially where items such as appliances, blinds, curtains, or garden features are being left behind. This is often handled through a fixtures and fittings list or a separate agreed schedule. I always advise clients to complete this list with care. A misunderstanding over whether the greenhouse or the integrated dishwasher is included can sour an otherwise smooth transaction. The list forms part of the contract, so it’s legally binding.

8. Special conditions

Special conditions tailor the standard form contract to the specific sale. These may cover:

• delayed completion;
• retention of funds after completion;
• tenant occupation;
• title indemnity insurance;
• gifted deposits;
• management company approvals; and
• apportionment of outgoings.

Special conditions are where many of the real risks in a transaction are dealt with, so they should be read carefully. For example, a retention clause might allow the buyer to hold back part of the purchase price until the seller fixes a known defect. These clauses are often heavily negotiated, and they can make or break a deal.

9. Standard conditions of sale

Most residential contracts incorporate standard conditions that deal with general points such as:

• notice requirements;
• liability for multiple buyers or sellers;
• VAT treatment;
• whether the buyer can assign the contract; and
• how joint obligations are enforced.

These clauses often go unnoticed, but they affect what happens if something goes wrong. For instance, the standard conditions typically set a default completion date if none is specified, and they outline the procedure for serving notices. They also limit the seller’s liability for certain matters. While they are “standard,” they are not trivial, and they can be amended by special conditions where needed.

10. Completion mechanics

The contract should explain how completion will happen, including the transfer of the balance of funds, the handover of keys, and any documents that must be delivered at completion. This is especially important where the property is part of a chain. The mechanics usually involve the buyer’s solicitor sending the completion funds to the seller’s solicitor by telegraphic transfer, and the seller’s solicitor confirming receipt and authorising the release of keys. Any delay in the transfer of funds can push completion past the agreed time, so clarity is essential.

Freehold vs leasehold: why it matters

The contract should make the tenure clear because the obligations differ significantly.

A leasehold contract often needs more detail because the buyer is taking on ongoing obligations to a landlord or management company. The buyer’s solicitor will need to review the lease terms, check for onerous ground rent clauses, and ensure any required landlord’s consent is obtained. Missing these steps can leave a buyer with unexpected costs or even affect the property’s mortgageability.

Common additional clauses to look for

Depending on the transaction, a property sale contract may also include:

• apportionment of ground rent, service charge, or council tax;
• conditions about vacant possession;
• agreement over chattels or excluded items;
• rights of way or access rights;
• planning or building regulation issues;
• seller warranties about disputes or notices;
• restrictions on use before completion;
• chain-related timing provisions.

These clauses are not always needed, but when they are, they can be decisive. For instance, a vacant possession clause is critical if the property is currently tenanted, because the buyer needs assurance that the tenant will have moved out by completion. Without it, the buyer could find themselves an accidental landlord with all the legal responsibilities that entails.

Practical checklist for reviewing a sale contract

Before exchange, check that the contract answers these questions:

• Are the buyer and seller named correctly?
• Is the property described with the right title number?
• Is the tenure correct: freehold or leasehold?
• Is the price correct?
• Is the deposit amount clear?
• Is the completion date fixed?
• Are fixtures and fittings listed properly?
• Are any special conditions understood?
• Are tenancy, possession, or occupier issues dealt with?
• Have all agreed terms been included in writing?

If any answer is unclear, the contract should be corrected before exchange. I’ve seen too many clients assume that a point “will be sorted later,” only to find that later never comes. Exchange locks the terms in place, so this is your last chance to get it right.

Mistakes that cause trouble

Leaving out agreed terms

If a key term was discussed but not included in the written contract, it may not be enforceable. The law requires all agreed terms to be in the written document, so a verbal side agreement about the garden shed or the completion date simply won’t hold up.

Using vague property descriptions

An imprecise description can lead to disputes over boundaries, outbuildings, parking spaces, or included land. I’ve seen cases where a buyer thought they were getting a strip of land at the side of the house, but the contract only described the main dwelling. The title plan should always be checked against the physical boundaries.

Ignoring leasehold obligations

A leasehold sale needs careful review of ground rent, service charges, restrictions, and landlord consents. Overlooking a doubling ground rent clause or a requirement for landlord’s consent to alterations can create serious problems down the line, including difficulty selling or remortgaging.

Treating the contract as a formality

Once contracts are exchanged, the deal is binding. That is why the drafting stage matters so much. I always tell clients to read every word, ask questions, and never assume that the other side’s solicitor has covered everything. A little extra care at this stage can prevent a lot of stress later.

Step-by-step: how the contract is usually prepared

1. The seller’s solicitor drafts the contract and standard particulars.
2. The buyer’s solicitor reviews the title and proposed wording.
3. Both sides negotiate special conditions if needed.
4. The contract is checked against the property information and fixtures lists.
5. Once both sides are satisfied, contracts are signed and exchanged.
6. The sale becomes legally binding at exchange.

This process can take weeks, and it’s not unusual for negotiations over special conditions to be the most time-consuming part. Both sides are trying to balance risk, and a good solicitor will explain the implications of each clause clearly.

When you should get legal help quickly

You should ask a conveyancer or solicitor to review the contract urgently if:

• the property is leasehold;
• the seller is a landlord or the property is tenanted;
• there are unusual access or boundary issues;
• the sale involves gifted money or a trust;
• there is a short completion deadline;
• the seller wants to retain items or impose unusual conditions;
• you do not understand a special condition.

These are the points where standard wording often is not enough. In these situations, the cost of legal advice is a fraction of the potential cost of getting it wrong.

FAQ

Is a verbal agreement enough to sell a property in England?
No. A sale contract for land must be in writing, include all agreed terms, and be signed by both parties.

When does the property sale become legally binding?
It becomes legally binding at exchange of contracts, not when an offer is accepted.

Do all property sale contracts use the same wording?
No. Residential sales often use the standard conditions of sale, but extra special conditions are usually added for the specific transaction.

What is the most important part of the contract?
The most important parts are the parties, the property description, the price, the completion date, the deposit terms, and any special conditions that change the standard position.

Can the contract include different terms if both sides agree?
Yes. The written contract should include all agreed terms, and special conditions can be added to reflect the deal the parties have made.

Conclusion

A property sale contract in England should do one job very clearly: record the full deal in a form that is legally enforceable and practical to complete. At minimum, it must identify the parties and property, set out the price and completion terms, and include every agreed condition in writing.

The safest approach is to read every clause before exchange and make sure the contract matches what was actually agreed in negotiations. In my experience, the transactions that run smoothly are the ones where both sides have taken the time to get the contract right from the start.
