Disputes about whether a contract exists at all are surprisingly common — often because one side assumed nothing was binding until "the paperwork" was signed. In England and Wales the paperwork is rarely what makes the contract.
The four elements
A contract is formed when four things are present:
- Offer — a clear proposal of terms, capable of acceptance.
- Acceptance — an unqualified "yes". A reply that changes the terms is a counter-offer, not an acceptance.
- Consideration — each side gives something: money, goods, services, or a promise.
- Intention to create legal relations — presumed in commercial dealings, and difficult to rebut.
Nothing in that list requires writing, a signature, or a particular form. An exchange of emails, a quote followed by "please go ahead", or a conversation followed by work starting can all form a binding contract.
When writing does matter
A few types of contract are only enforceable if they are in writing:
- Contracts for the sale or other disposition of land must be in writing, contain all agreed terms and be signed by both parties (s.2 Law of Property (Miscellaneous Provisions) Act 1989).
- Guarantees — a promise to answer for someone else's debt — must be evidenced in writing and signed by the guarantor (Statute of Frauds 1677, s.4).
- Assignments of certain rights, and some consumer credit agreements, have their own formality rules.
Outside those categories, writing is about evidence, not validity.
Electronic signatures and emails
An electronic signature, including a typed name at the foot of an email, can satisfy a signature requirement where the person intended it to authenticate the document. The Law Commission confirmed this in 2019, and the courts have applied it since. Automatic email footers are more contested; a deliberate sign-off is on firmer ground.
Battle of the forms
Where both sides send their own standard terms — your quote with your conditions, their purchase order with theirs — the contract is usually made on the terms of whoever fired the last shot before performance began without objection. Businesses lose disputes over payment terms, liability caps and warranties this way every week. If the terms matter, make sure the last document before work starts is yours, and that they accepted it.
Entire agreement and no-reliance clauses
Most professionally drafted commercial contracts contain an entire agreement clause. Its effect is to shut out pre-contract statements — the reassurance in a meeting, the capability described in a pitch — as terms of the contract. A well-drafted clause will also exclude claims for misrepresentation based on those statements, though it cannot exclude liability for fraud.
If you were induced to sign by something said outside the document, you need to know whether the contract has one of these clauses before you spend money on a claim.
Deeds: the twelve-year contract
A contract executed as a deed — signed, witnessed, and stating on its face that it is a deed — does not need consideration, and the limitation period for suing on it is twelve years instead of six (s.8 Limitation Act 1980). Construction contracts, guarantees and some property agreements are often deeds for precisely that reason. Check the signature block: it tells you which clock you are on.
What a solicitor will want from you
- Every document that could form part of the contract: quotes, emails, purchase orders, terms and conditions, and the chronology of who sent what and when.
- Notes of any conversations where terms were agreed, with dates and who was present.
- Evidence that work started, goods were delivered, or money changed hands — conduct is often the best proof that a contract existed.
- The other side's terms, if they sent any.

Frequently asked
Is a verbal agreement legally binding in the UK?
Generally yes, in England and Wales, provided there is offer, acceptance, consideration and an intention to create legal relations. The difficulty is proof, not validity. A few contracts must be in writing — including transfers of land and guarantees — and some must be signed as deeds.
What is an entire agreement clause?
A clause stating that the written document is the whole contract and that neither party relies on anything said outside it. It is common in commercial contracts and can prevent you from relying on assurances given in meetings or emails before signature.
