An oral contract is a legally binding agreement made through spoken words rather than a written document. Contrary to the common belief that contracts must be written and signed to be enforceable, many agreements can be legally binding even where nothing has been put on paper. Businesses and individuals often rely on oral contracts because they are convenient, quick and can arise naturally during conversations or negotiations, particularly where parties have an established relationship or need to act quickly.

However, oral agreements can create challenges when disputes arise. The key questions are whether a valid contract was formed, what its terms were and whether those terms can be proved if the parties later disagree.

In this guide, we explore when oral contracts are enforceable, how their existence can be established, the types of disputes that can arise and the evidence courts may consider. We also provide practical tips for reducing uncertainty and protecting your position when an agreement has been made verbally.

What is an Oral Contract?

An oral contract is an agreement made verbally between two or more parties, without the terms being documented in a written contract. While written contracts are generally preferred because they provide a clear record of what was agreed, an agreement does not automatically become less legally binding simply because it was made verbally.

In the UK, oral or verbal contracts can be legally binding, as long as the usual requirements for a valid contract are met. Typically, this means that:

• the parties have reached an agreement, exchanged something of value (known as consideration) and intended to create legal relations
• the terms of the agreement must be sufficiently clear for the parties’ obligations to be understood.

Oral contracts can arise in everyday business and personal situations. For instance, two businesses might agree during a meeting that one will provide services for an agreed fee. A customer might verbally accept a quote for work, or two parties might make a “handshake deal” to move forward with a transaction. Family members may also enter into verbal contracts regarding loans, especially where money is lent on the understanding that it will be repaid at a later date.

The difficulty often arises later. If the parties disagree, there may be no single document, showing what was agreed, when the payment was due or what each party was expected to do. An oral contract may therefore be enforceable, but proving its terms can be much harder than proving the contents of a signed written contract.

For this reason, important agreements should ideally be recorded in writing, even where the initial agreement was made verbally.

Are Oral Contracts Enforceable in the UK?

In the UK, oral contracts are generally enforceable, and the focus is on whether the parties have formed a valid agreement and whether its terms can be established.

A valid contract will generally need: offer, acceptance, consideration and an intention to create legal relations. In simple terms, one party must make an offer, the other must accept it, both sides must exchange something of value, and they must intend their agreement to have legal consequences. In commercial arrangements, an intention to create legal relations is normally easier to establish than in informal family or social arrangements.

However, there are important exceptions. Certain types of agreement must satisfy specific statutory formalities. For example:

• Land: Under section 2 of Law of Property (Miscellaneous Provisions) Act 1989, contracts for the sale or other disposition of an interest in land generally need to be in writing, contain all expressly agreed terms and be signed by or on behalf of each party.
• Guarantees: Under Section 4 of the Statute of Frauds (1677), a guarantee generally needs to be evidenced in writing and signed by the guarantor to be enforceable.
• Consumer credit: Regulated consumer credit agreements are subject to detailed formal requirements under the Consumer Credit Act 1974, including requirements concerning the form and signing of agreements.
• Other agreements: Certain transactions, including some employment settlements and transfers or assignments of particular rights, may also be subject to specific statutory or contractual formalities.

The important point to note is that an oral contract is not automatically unenforceable simply because it is made orally. However, where the law requires written formalities, failing to meet them can prevent an agreement from being enforced. Even where no written document is legally required, the lack of one can make proving exactly what was agreed can be much more difficult.

Proving the Existence of an Oral Contract

If a disagreement arises, the party relying on the oral agreement will typically need to demonstrate, on the balance of probabilities, that a contract was in place and that its key terms can be identified. This means showing that it is more likely than not that the alleged agreement was made.

The usual contractual requirements remain relevant: offer, acceptance, consideration and an intention to create legal relations. However, since there is no signed document setting out the agreement, other evidence can become particularly important.

What Evidence Can Help?

Witness testimony can offer insights from individuals who were present during the discussion of the agreement or who heard the terms being settled. However, where accounts conflict, the court will consider which evidence is most credible. 

Emails, texts, and other forms of written communication can also be quite useful. For instance, an email sent shortly after a phone call that confirms what was agreed upon can bolster a party’s position. Messages that discuss payment, deadlines, or responsibilities may also serve as valuable evidence, even if they do not contain the contract itself.

The parties’ conduct following the agreement can also be important. Delivering goods, providing services, making payments, or otherwise acting in line with the alleged agreement may help to demonstrate that both parties understood a binding arrangement to exist. This principle overlaps with the doctrine of part performance, which can also help establish that an agreement existed.

Common Challenges

One of the main difficulties is contradictory accounts. If each party recalls the conversation differently, the court may examine the surrounding evidence to ascertain what is most likely to have occurred.

There may also be ambiguity regarding the terms. If important details were never discussed or the language used was too vague, it could be challenging to prove that a sufficiently defined contract existed.

Consequently, courts will evaluate the evidence as a whole, including contemporaneous documents, witness testimonies, the parties’ subsequent actions, and the surrounding commercial circumstances. Keeping a written record of important discussions can make this process considerably easier.

Oral Contract Examples and Common Disputes

Informal arrangements can become contentious when the parties later have different understandings of their obligations. This is particularly common where important details, such as payment, deadlines or responsibilities, were discussed verbally but never recorded. Some of the most common disputes include:

• Unpaid services are a common source of disagreement. For example, a business may agree verbally to provide work without confirming the price, payment date or scope of the work. The parties may later disagree about how much is owed, what work was included or whether it was completed to the agreed standard.
• Loan repayment disputes can arise when money is lent between friends, relatives or business contacts without written terms. Without a record of the arrangement, it may be difficult to establish whether the money was intended as a loan or a gift, when it was due to be repaid or whether interest was agreed.
• Verbal changes to existing contracts can also create uncertainty. Parties may agree during a telephone call or meeting to change a price, deadline or other term without updating the original agreement. If a dispute later arises, one party may rely on the original written agreement while the other argues that the terms were subsequently changed.
• Agreements between friends and family members can become contentious when relationships break down. A high level of trust may mean that parties do not document their arrangements, leaving limited evidence of what was promised. Where these disagreements cannot be resolved directly, our civil litigation team can advise on recovering money you are owed.

These examples demonstrate why important verbal agreements should be confirmed in writing. Even a simple email or message confirming the key terms can provide valuable evidence if a disagreement later arises.

How to Strengthen and Protect Oral Agreements

Although oral agreements can be legally binding, practical steps can be taken to create a clearer record and reduce the risk of future disputes:

• Confirm the agreement in writing. After discussing verbally, send a brief email or message that summarises the key terms, including the price, deadlines, responsibilities and any conditions. Asking the other party to confirm that the summary is correct can serve as useful evidence of the agreement.
• Keep clear records. Save relevant emails, text messages, invoices, receipts and records of payments or work completed. These documents can help demonstrate both what was agreed and how the agreement functioned in practice.
• Be clear about important terms. Agree what each party is responsible for, when it must be done and what will happen if something goes wrong. Avoid relying on vague statements or assumptions.
• Use witnesses where appropriate. If important terms are agreed in a meeting, having another person present may provide additional evidence about what was said. Recording conversations should only be done where it is lawful and appropriate.
• Put complex arrangements in writing. For major transactions, long-term business relationships or agreements involving large sums of money, a formal written contract is usually the safest approach. It can also set out procedures dealing with changes, termination and disputes.
• Agree how disputes will be resolved. Consider agreeing a clear process for raising concerns and resolving disagreements, such as requiring the parties to discuss the issue first, and where appropriate, attempting mediation before resorting to court proceedings.
• Act promptly if something goes wrong. If the other party appears to have breached the agreement, raise the issue quickly and keep a written record of your response. This can help establish your position and may prevent the situation from escalating.

Where the agreement is particularly valuable or complex, seeking legal advice early on can help identify risks and determine whether the arrangement should be formally documented.

Legal Remedies for Breach of an Oral Contract

If an oral contract is legally binding and one party fails to fulfil their obligations, the other party may have several remedies available. The appropriate remedy will depend on the circumstances, the loss suffered and what can be established about the agreement.

Damages are the most common remedy, intended to compensate the innocent party for the loss caused by the breach. For example, this could include the cost of obtaining replacement services or losses resulting from non-payment.

Restitution may be available where one party has received a benefit that it would be unjust to retain. In appropriate circumstances, this may involve returning money or other benefits provided under an agreement. Restitution is a separate remedy from damages and will depend on the circumstances of the case.

Specific performance is a court order requiring a party to perform their contractual obligation. It is an exceptional remedy and is generally only appropriate where damages would not provide an adequate remedy, such as in certain transactions involving unique property. It is not normally suitable for contracts requiring ongoing personal cooperation.

Time Limits

There is also a time limit for bringing a claim. Under Section 5 of the Limitation Act 1980, claims based on a simple contract will generally need to be brought within six years of the date the right to bring the claim arose.

The rules around limitation can be complicated, and exceptions may apply in some circumstances. If an oral contract has been breached, it is therefore important to consider taking legal advice promptly rather than waiting until the limitation period is close to expiring.

Practical Tips for Clients and Lawyers

The main risk with an oral contract is often not whether it can be legally binding but whether the parties will be able to prove what was agreed. Clients and lawyers can reduce this risk by taking a few straightforward steps.

First, put important agreements in writing wherever possible. A written contract provides clear evidence of the parties’ intentions and reduces the risk of misunderstandings. If an agreement has already been agreed verbally, follow up with an email confirming the key terms, such as price, deadlines and responsibilities.

Second, take care when making changes to an existing written contract. Agreeing amendments verbally can create uncertainty over which terms apply. Any important changes should therefore be recorded in writing and, where appropriate, formally signed.

Third, keep organised records. Emails, text messages, meeting notes, invoices, payment records and other communications may all help demonstrate what was discussed and how the parties subsequently acted.

Finally, seek legal advice promptly if a disagreement arises. A specialised lawyer can consider whether a binding agreement exists, assess the available evidence, advise on potential remedies and identify any applicable time limits.

For lawyers, the practical lesson is equally straightforward: make the contractual terms clear, document important agreements and ensure clients understand the risks of relying on verbal promises. Taking these steps at the outset can help prevent costly disputes later.

How Witan Solicitors Can Help

Oral contracts can be legally binding, but the absence of written terms can make disagreements more difficult to resolve. The main challenges often concern proving what was agreed, establishing the parties’ obligations and determining whether any changes were subsequently made.

Where possible, important arrangements should therefore be put in writing. If an agreement is made verbally, keeping records of emails, messages, payments, invoices and other communications can provide valuable evidence of what was agreed and how the parties acted afterwards.

If a dispute does arise, acting promptly is important. Early advice can help establish whether a binding agreement exists, what evidence is available, what remedies may be appropriate and whether any limitation period applies.
