He Said It on WhatsApp — But Is It a Legal Admission? Electronic Messages in UAE Commercial Disputes

A short message sent in the ordinary course of business may later become one of the most significant pieces of evidence in a commercial dispute. WhatsApp messages and emails may be relied upon to establish a debt, approval, instruction or term of dealing, but their significance does not arise merely from their existence.

UAE law expressly brings electronic correspondence and modern means of communication within the statutory framework of electronic evidence. What a particular message actually proves, however, may depend on its authenticity, attribution, complete context, the capacity and authority of its sender, whether any extract is identical to its electronic record and its consistency with the contract, invoices and wider commercial records.

Managing electronic communications is no longer merely an operational issue. It forms part of a company's legal risk management framework.

As more employees approve prices, additional works, discounts, payment arrangements and commercial instructions through instant messaging, businesses need clear limits of authority, reliable preservation of material communications and appropriate formal documentation of significant commercial decisions.

A company may have a carefully drafted contract while the commercial relationship itself is managed through hundreds of messages. When a dispute arises, the gap between the formal contractual record and day-to-day commercial practice can become a significant evidential risk.

Federal Decree-Law No. 35 of 2022 Promulgating the Law of Evidence in Civil and Commercial Transactions establishes the UAE statutory framework governing electronic evidence. Article 53 defines electronic evidence, while Article 54 identifies its forms, including electronic correspondence, emails and modern means of communication.

WhatsApp communications may therefore fall within this statutory framework as electronic correspondence transmitted through modern means of communication. Their classification and evidential effect must nevertheless be assessed in accordance with the requirements of the Evidence Law and the circumstances of the particular dispute.

The Law goes further than simply recognising this category of evidence. Article 55 provides that electronic evidence is subject to the rules governing documentary evidence under the Law. Article 59 further provides that, save as otherwise provided in Article 56, electronic evidence has the same probative value as informal instruments pursuant to the provisions of the Law.

This distinction matters. Classification as electronic evidence does not make every message conclusive proof of every fact asserted by the party relying upon it. Recognising a communication as electronic evidence addresses the nature of the evidential medium. Determining what the message actually proves, against whom it may be relied upon and what legal effect may be attributed to its contents requires a separate analysis.

This becomes particularly important where a message is relied upon as an acknowledgement of debt. A statement such as “We will arrange the payment next week” may carry considerable significance, but it does not necessarily constitute an acknowledgement of the entire amount claimed.

A party may acknowledge the existence of an obligation while disputing its amount. It may acknowledge one invoice but dispute others. It may confirm receipt of goods while maintaining a dispute concerning their quality. Equally, an acknowledgement of an underlying debt should not automatically be treated as an acknowledgement of the final balance or every component of a wider claim.

Context may therefore be decisive. An isolated message may convey a materially different meaning from the complete sequence of communications. Earlier or later messages may show that an apparent acknowledgement was conditional. Conversely, a party may describe later communications as negotiations even though the preceding correspondence shows that the debt had already been acknowledged and the subsequent discussion concerned only the timing or method of payment.

The message itself may also be undisputed while its attribution or legal effect remains contested. The appearance of a manager's or employee's name on a screenshot does not necessarily resolve who controlled the relevant telephone number or account, whether the conversation is complete or whether the communication originated from the person to whom it is attributed.

A further distinction must be drawn between attribution of a message to its sender and the sender's authority to bind the company. Establishing that a project manager, salesperson, accountant or procurement officer sent a particular message does not necessarily establish that everything stated in it is legally binding on the company.

The sender's position, scope of authority, previous course of dealing and the company's subsequent conduct may all become relevant, particularly where the communication purports to confirm a debt, vary a price, approve additional works, extend a payment period or accept a settlement.

The Evidence Law also addresses challenges to the validity of electronic evidence. Article 57 regulates informal electronic evidence in the circumstances specified by the Law, unless otherwise established. Article 58 places the burden of proving the invalidity of the electronic evidence referred to in Articles 56 and 57 on the litigant alleging its invalidity.

Screenshots and other electronic extracts require equal precision. It is not correct to assume that a screenshot has no evidential significance merely because it is not the original device or underlying conversation. Equally, the mere production of a screenshot does not make it complete or conclusive evidence.

Article 60 regulates the production of electronic evidence, including production in its original format or by any other electronic means. Article 63 provides that extracts of electronic evidence have the probative value prescribed for the electronic evidence itself to the extent that such extracts are identical to its electronic record.

Whether an extract is identical to its electronic record may therefore become central where completeness or accuracy is genuinely disputed. The source from which the communication was extracted, the completeness of the conversation, omitted messages or attachments and the ability to verify the material may all become relevant.

Articles 61 and 62 further address the verification process. Article 61 regulates the consequences where a litigant, without an acceptable excuse, fails to produce what the court requires for the purpose of verifying the validity of electronic evidence. Article 62 addresses the situation in which the validity of electronic evidence cannot be verified for a reason not attributable to the litigants, in which case the court assesses its probative value in light of the circumstances of the case.

The issue of authenticity is therefore not always a simple binary question of whether a message is genuine or fabricated. A dispute may concern its source, completeness, method of extraction, whether an extract is identical to its electronic record or whether the available electronic data permits verification. Where the dispute is genuinely technical, digital forensic examination or expert evidence may become relevant.

Electronic communications may also contribute to proving the formation of an agreement or some of its terms. A supplier may send a quotation by email and receive a WhatsApp response stating “Approved. Proceed”, followed by performance.

In such circumstances, the sequence of communications may become relevant to identifying what was offered, what was accepted, who issued the approval, whether that person had authority and whether the parties' subsequent conduct corresponds with the communications.

This does not mean that every approval sent through WhatsApp automatically creates a binding contract. Electronic communications cannot dispense with a particular legal formality where one is required for a specific transaction. Their legal effect remains dependent on the nature of the transaction, the contents of the communications, the capacity and authority of the parties involved and the applicable legal requirements.

The analysis becomes more complex when the written contract says one thing while subsequent communications suggest a different course of dealing. A later WhatsApp message should not automatically be treated as varying the contract. Equally, subsequent communications do not become irrelevant merely because a written contract exists.

They may be relevant to proving instructions, approvals, knowledge of a fact, performance or subsequent conduct. Whether they alter the contractual obligations themselves will depend on the wording of the contract, any agreed mechanism for variations or approvals, the authority of the sender and the parties' conduct.

The same caution applies to settlement communications. An offer to pay a particular amount in order to resolve a dispute does not automatically constitute an acknowledgement of the entire claim. The wording and context of the communication, and whether it contains an independent acknowledgement of a particular fact or merely a commercial proposal to resolve the dispute, require careful analysis. Conversely, describing a communication as a “settlement negotiation” does not automatically negate an otherwise independent acknowledgement contained within it.

Electronic evidence is not confined to written text. Voice notes, images, documents, attachments and other digital files may all form part of the evidential record. A voice note may contain a clearer instruction than a series of text messages, while an attached document may be the quotation to which a subsequent approval refers. Preserving the source and context of such material becomes particularly important where authenticity, alteration or completeness may later be challenged.

Even a short response or an emoji may acquire significance from its context. “OK”, “Noted”, “Proceed” or 👍 should not be assigned a fixed legal meaning in isolation. Their significance may depend on the precise message to which they respond and the conduct that follows.

Finally, electronic evidence rarely operates in isolation in a substantial commercial dispute. A WhatsApp message may sit alongside a contract, invoice, purchase order, bank transfer, delivery note or statement of account. The evidential picture becomes stronger or weaker according to the way these materials interact.

The true significance of electronic communications therefore lies not in treating them as an evidential island, but in assessing them as part of the complete evidential record of the commercial relationship.

Electronic evidence should be protected before proceedings begin. Once a serious dispute is anticipated, relevant communications and electronic data should be treated as potential evidence and preserved in a manner that allows them to be examined alongside the contract, financial records and other documents forming part of the commercial relationship.

An effective electronic evidence strategy does not begin by selecting the most favourable screenshots. It begins by reconstructing the commercial relationship and identifying precisely what each item of evidence proves, and what it does not.

• Preserve complete conversations rather than selected screenshots.
• Retain relevant attachments, voice notes, dates and available electronic data.
• Verify the telephone number or account and the identity of the person to whom the communications are attributed.
• Review an employee's position and scope of authority where a message contains an approval, instruction or acknowledgement.
• Read each message within the complete context of the conversation, including what preceded and followed it.
• Where authenticity or completeness is disputed, assess whether an extract of electronic evidence is identical to its underlying electronic record.
• Cross-check communications against contracts, invoices, purchase orders, bank transfers, statements of account and delivery records.
• Avoid unnecessary deletion or alteration of relevant electronic data once a dispute is reasonably anticipated.
• Formally document material commercial agreements and variations where the nature of the transaction requires or warrants it.
• Assess settlement communications carefully and distinguish an independent acknowledgement of fact from a commercial proposal intended to resolve a dispute.
• Consider technical examination where there is a genuine dispute concerning authenticity, integrity, attribution or the electronic source.
• Assess the strengths and weaknesses of electronic evidence before relying upon it before the court or an appointed expert.
