No contract, no payment? Why you can still recover

A verbal agreement can be legally binding in England and Wales even where nothing was formally signed. As with other contracts, the usual requirements include agreement, an intention to create legal relations, consideration and sufficiently certain terms. Commercial arrangements are generally presumed to be intended to have legal effect. The absence of a signed document therefore does not automatically mean there is no contract. What often changes is how easily you can prove exactly what was agreed.
Some transactions have specific formalities, however. Guarantees and contracts for the sale or other disposition of an interest in land are important examples.
Why the lack of paperwork worries people more than it should
The instinct is often that no signature means no enforceable agreement. English contract law does not work that way for ordinary commercial contracts. A court can consider communications, conduct and the surrounding circumstances when deciding whether an agreement existed and what its terms were.
A spoken agreement followed by delivery of goods or services, invoicing and payment can provide persuasive evidence. Problems are more likely to arise where the parties disagree about a specific term, such as the price, scope of work or payment date. The practical risk is therefore usually proving the terms rather than proving that commercial dealings occurred.
What actually counts as evidence
| Evidence type | Why it helps |
|---|---|
| Emails or texts confirming the job | Can show what both parties discussed and accepted |
| Quotes or estimates sent beforehand | Can support evidence of the proposed price and scope |
| Purchase orders or job references | Can show the customer authorised the work |
| Delivery notes or signed timesheets | Help prove goods or services were supplied |
| The invoice itself, sent promptly | Records the amount you asserted was due, although it does not alone prove agreement |
| Part payment already made | Can support the existence of an obligation, depending on the circumstances |
| WhatsApp messages or call records | Electronic communications can provide evidence of negotiations and agreed terms |
Start collecting evidence as soon as you suspect an invoice may be challenged. If a query arises, deal with it properly through our step by step approach to disputed invoices. An unresolved objection can become important evidence if the dispute later reaches court.
The exceptions that do need writing
Some agreements are subject to statutory formalities. Section 4 of the Statute of Frauds 1677 applies to a promise to answer for another person’s debt, default or miscarriage. An action on such a guarantee generally requires the agreement, or a memorandum or note of it, to be evidenced in writing and signed by the person against whom enforcement is sought. A director’s purely verbal promise to guarantee a company’s debt should therefore not be treated as equivalent to a properly documented personal guarantee.
Contracts for the sale or other disposition of an interest in land are also subject to formal requirements. Section 2 of the Law of Property (Miscellaneous Provisions) Act 1989 generally requires the contract to be in writing, to incorporate all expressly agreed terms and to be signed by or on behalf of each party.
Most ordinary supply and service agreements do not fall into those categories and can potentially be enforceable without a signed contract. If personal liability is important, our guide to security options beyond personal guarantees covers alternatives that can be documented before the next transaction.
Chasing the debt without a signed contract
The recovery process remains broadly similar. Send clear written correspondence setting out the goods or services supplied, the amount you say was agreed, the outstanding balance and the evidence supporting your position. Our guide to writing a debt collection letter covers the structure.
Statutory late-payment rights can also apply to qualifying business-to-business contracts for goods and services even where the agreement was not contained in a signed document. Where applicable, statutory interest is 8% above the Bank of England base rate. Fixed debt-recovery compensation may also be available. A different contractual interest remedy can affect whether statutory interest applies. The current rules are explained in our guide to claim statutory interest on late payments.
Where the customer disputes the amount, scope or quality of the work, investigate that issue before escalating. Our resolution flowchart sets out a structured way to deal with disputed invoices.
When to escalate
Once you have gathered the evidence and sent appropriate correspondence, treat the account in the same disciplined way as other overdue debts. The warning signs in when to escalate an invoice still apply.
Where insolvency action is being considered, using statutory demands properly is particularly important. A statutory demand gives the debtor 21 days to pay or reach an agreement. Failure to respond can potentially support a bankruptcy petition against an individual owing at least £5,000 or a winding-up petition against a company owing at least £750. It should not be used as a routine collection threat where the debt is genuinely disputed.
Reduce the risk next time by agreeing terms before work begins, as covered in writing watertight terms and conditions, and consider a business credit check before extending substantial credit.
If the customer is overseas, enforceability, jurisdiction and applicable law can differ, so seek specialist international debt collection advice rather than assuming English rules automatically govern the transaction.
Construction contracts also have their own statutory payment and adjudication framework. Importantly, the former requirement for the Construction Act provisions to apply only to agreements in writing was repealed, meaning qualifying oral construction contracts can fall within the statutory regime. Our construction debt recovery service covers those industry-specific issues.
Frequently asked questions
Can you win a court claim without a written contract?
Yes. A signed contract is not required for every type of agreement. You must still prove, on the balance of probabilities, that a binding agreement existed, what its relevant terms were and that payment became due.
Does a text message count as a contract in the UK?
It can form part of a binding agreement if the communications, read in context, establish the necessary contractual elements. Even where the message itself does not create the whole contract, texts and WhatsApp exchanges can be useful evidence of what the parties discussed and agreed.
What if the customer denies the work was ever agreed?
Collect evidence showing authorisation and performance. Emails, messages, purchase orders, delivery records, timesheets, photographs and payment history can all be relevant. Part payment may support your case, although its significance depends on what the payment was for and whether any terms remained disputed.
Next steps
Gather everything showing what was agreed, authorised, supplied and invoiced before sending another chase. If the debt is significant and the customer has stopped engaging, speak to our commercial debt collection agency for an initial assessment of the available recovery options.
