TL;DR: Verbal agreements legally binding under English law can still be nearly impossible to enforce. Without written evidence, proving what was agreed is costly and uncertain. Always confirm agreements in writing.
Verbal agreements can be legally binding in the UK, but that doesn’t make them safe to rely on. If something goes wrong, proving what was actually agreed becomes the entire problem.
Most people have been there. A conversation over coffee, a nod across a desk, a phone call that ends with ‘we’re good to go’. It feels solid. Both parties leave with a clear understanding, or so they think. Then a project stalls, a payment doesn’t arrive, or someone remembers the deal very differently. Suddenly you’re not talking about the work anymore. You’re talking about what was said, when, and whether anyone can prove it.
The handshake deal gone wrong is one of the oldest business problems there is. It’s also one of the most avoidable.
Yes, in many cases they are. Under English law, a contract doesn’t need to be written down to be enforceable. What it needs is offer, acceptance, consideration (something of value exchanged by both sides), and an intention to create legal relations. A verbal agreement can satisfy all of those criteria.
So far, so reassuring. The trouble is that ‘legally binding’ and ‘practically enforceable’ are two different things. A verbal contract might technically exist, but if you end up in a dispute, you’ll need to demonstrate what was agreed, on what terms, and that both parties understood and accepted those terms. Without written evidence, that becomes very difficult and very expensive to establish.
There are also exceptions. Some agreements must be in writing by law. Property transactions, for example, require a written contract under the Law of Property (Miscellaneous Provisions) Act 1989. Consumer credit agreements and certain types of insurance have similar requirements. If your verbal agreement falls into one of these categories, it may not be enforceable at all, regardless of what was said.
The word ‘contract’ implies precision. When you write one down, both parties have to commit to specific language, and that language is what the courts interpret. A verbal agreement, by contrast, is reconstructed from memory. Memory is unreliable at the best of times. Under financial pressure, it becomes creative.
I’ve seen businesses spend more on legal fees trying to prove what was agreed than the original deal was worth. That’s not a hypothetical. It’s a pattern. One side says delivery was agreed within 30 days. The other insists it was 60. One party believes the price included VAT. The other is adamant it didn’t. Neither is necessarily lying. They just genuinely remember it differently, because nothing was written down to anchor the agreement.
Courts will look at surrounding evidence: emails, text messages, bank transfers, witness testimony, industry norms, prior dealings between the parties. That process takes time and money. And the outcome is never certain. Oral contract enforceability isn’t about whether a verbal deal exists. It’s about whether you can convince a judge that your version of events is more credible than the other side’s.
Informal agreements feel efficient. Skipping the paperwork saves time and avoids the slightly awkward formality of sending a contract to someone you trust. That logic works until it doesn’t.
The risks are asymmetric. When things go well, the lack of a written contract barely matters. When things go wrong, it’s the only thing that matters. A client who delays payment can simply dispute the agreed terms. A supplier who underdelivers can claim the specification was never that clear. A business partner who walks away can argue the arrangement was never formalised. In each case, the absence of documentation hands the other party a ready-made defence.
There’s also the issue of scope creep. Without a written agreement, there’s no fixed reference point for what was included in a project. Work expands. Expectations shift. The client remembers the conversation as covering everything. The supplier remembers it as covering a very specific scope. That gap is where business contract disputes are born.
Most informal agreements aren’t made with strangers. They’re made with people you know, respect, and trust. That’s precisely why they feel safe. And that’s also why they can be so damaging when they fall apart.
A dispute with someone you trusted professionally is rarely just a contractual problem. It becomes personal. Communications break down. Positions harden. What might have been a straightforward contractual matter turns into an expensive, protracted argument that damages both parties, regardless of who is technically right.
A clear written agreement doesn’t signal distrust. It signals that both parties take the arrangement seriously enough to define it properly. That framing matters.
The answer isn’t to become paralysed by paperwork or to treat every conversation like a legal proceeding. It’s to build simple, consistent habits around documentation.
At minimum, follow up any significant verbal conversation with a written summary by email. ‘As we discussed, the agreed scope is X, the fee is Y, and delivery is expected by Z. Please confirm you’re happy with this.’ That email, if the other party doesn’t contradict it, becomes contemporaneous evidence of the agreement. It takes two minutes and it protects both sides.
For anything beyond a straightforward transaction, use a proper written contract. It doesn’t need to be a 40-page document drafted by a QC. A clear, plain-English agreement covering the scope, price, timeline, payment terms, and what happens in the event of a dispute will do the job. Templates are widely available, and a solicitor can produce a serviceable standard contract for a reasonable fee that will save you multiples of that cost if things go wrong.
Also consider what your contract says about dispute resolution. Many business disputes never need to reach court if the contract specifies a process, whether that’s mediation, arbitration, or a simple escalation procedure. That clause alone can save a working relationship that would otherwise be destroyed by litigation.
It can, but it rarely does without supporting evidence. Courts will consider emails, messages, invoices, payment records, and witness accounts to piece together what was agreed. The more documentation exists around the verbal agreement, the stronger your position. Without any supporting evidence, you are essentially asking a judge to decide whose account of a conversation is more believable.
In England and Wales, contracts for the sale or transfer of land must be in writing. Consumer credit agreements are also required to be written and signed. Certain regulated financial and insurance products have similar requirements. If you’re unsure whether your agreement falls into a regulated category, it’s worth checking with a solicitor before relying on a verbal understanding.
Text messages can be valuable evidence. They’re time-stamped, they’re tied to identifiable parties, and they’re difficult to fabricate after the fact. A text that confirms the key terms of a discussion, and receives a positive response, is far more useful than a disputed recollection. It won’t substitute for a formal contract in complex arrangements, but it’s considerably better than nothing.
Frame it as standard practice, which it should be. ‘I do this with everyone I work with’ removes the implication that you distrust the specific person. You can also position it as being in their interest too, because a clear agreement protects both parties equally. If someone is genuinely offended by the suggestion of a written contract, that reaction itself tells you something worth knowing before you commit to the arrangement.
The question worth sitting with is this: if the person you’re making a verbal agreement with turned around tomorrow and remembered it entirely differently, would you have anything concrete to point to? If the answer is no, the problem isn’t the other person. It’s the process.
