Can a verbal agreement be legally binding?
Yes, in most cases — the real risk isn't whether it counts, it's proving what was actually said.
Yes — English law doesn't generally require a contract to be written down to be valid. A verbal agreement can be just as legally binding as a signed document, as long as it contains the same core ingredients any contract needs: an offer, an acceptance of that offer, something of value exchanged (consideration), an intention by both sides to be legally bound, and terms clear enough that a court could actually enforce them. Where those elements are present, a handshake deal can hold up in court — the challenge is proving it, not whether it legally counts.
What has to be present for a verbal deal to count
| Element | What it means |
|---|---|
| Offer and acceptance | One side proposes clear terms, the other agrees to them |
| Consideration | Something of value moves both ways — typically payment for goods or services |
| Intention to create legal relations | Both sides genuinely intended to be bound — generally presumed in business dealings, less so in casual social arrangements |
| Certainty of terms | The deal is specific enough that a court could work out what was actually promised |
The contracts that must be in writing regardless
- Land and property: contracts for the sale or transfer of land, or leases over 3 years, must be made in writing and signed under the Law of Property (Miscellaneous Provisions) Act 1989.
- Guarantees: a promise to answer for someone else's debt needs to be in writing under the Statute of Frauds 1677.
- Consumer credit agreements: these are generally required to be documented in writing under consumer credit law.
- Some other specific agreements: certain residential tenancy agreements and employment-related documents also have statutory writing requirements.
Outside these specific categories, an oral agreement is widely recognised as capable of being just as enforceable as a written one.
Why proof, not validity, is the real problem
Even where a verbal agreement is technically binding, a dispute usually comes down to one side's word against the other's about exactly what was agreed. Useful evidence includes any follow-up written communication — a confirming email or text — invoices or purchase orders that reflect the discussed terms, witnesses to the conversation, and conduct consistent with the deal, such as one party starting work and the other making payments toward it. Where no such evidence exists, proving the contract's specific terms can be genuinely difficult, even though the agreement was legally real.
What to do if you're relying on a verbal agreement
- Send a follow-up written message summarising what was agreed as soon as possible — this creates evidence even if the original agreement was spoken.
- Keep any invoices, receipts, or purchase orders connected to the deal.
- If a dispute arises, gather everything that shows the agreement's terms and any conduct consistent with it (payments made, work started).
- If the subject matter falls into one of the categories that legally requires writing (land, a guarantee, consumer credit), recognise that a verbal version of that specific deal likely isn't enforceable, regardless of how clear the conversation was.

How do you prove a verbal contract existed? Useful evidence includes follow-up emails or texts confirming what was discussed, invoices or purchase orders reflecting the agreed terms, witness accounts of the conversation, and conduct by both parties consistent with the agreement, such as one side starting work and the other paying for it.
