The role of expert reports in UAE civil and commercial proceedings is governed by the Federal Evidence Law and the Civil Procedures Law. Courts use expert appointments to resolve technical questions requiring specialist knowledge. Financial disputes involving contested accounts, valuations, or damages calculations are the most common category. Understanding the process from appointment to judgment helps parties and their legal advisers prepare more effectively.
How a Court Appoints an Expert
A court may appoint an expert at any stage of civil or commercial proceedings when it determines that technical analysis is required. The appointment is made by a court order specifying the mandate: the precise financial questions the expert must address.
Appointment is made from the Ministry of Justice's national register of approved experts, classified by specialisation. The court selects from the relevant specialisation. Parties do not choose the expert, but may petition the court to replace one on grounds of conflict of interest, insufficient qualification, or procedural irregularity.
Expert costs are typically borne by the parties, with final allocation depending on the outcome of the case. The court usually requires a cost deposit at the time of appointment.
The Expert's Process and Report
Once appointed, the expert receives the court file. Both parties must provide the expert with access to documents relevant to the assignment. The expert may request specific documents through the court. Parties who fail to produce requested documents risk adverse inferences in the court's final assessment.
The report must address each question in the court order directly. It must identify the documents reviewed, the methodology applied, and the basis for each conclusion. A report that goes beyond the mandate, addresses legal questions rather than financial ones, or relies on documents not produced by the parties is open to challenge.
After submission, both parties receive a copy and have a defined period in which to file written objections. These objections are formal pleadings. The court may refer them to the expert for response, or may appoint a supplementary expert to address disputed points. The objection stage is the primary procedural opportunity to challenge expert findings.
How Courts Weigh Expert Reports
Under UAE civil procedure, the judge is not bound to accept the expert's findings. The report is evidence evaluated alongside all other evidence. In practice, however, UAE courts give substantial weight to court-appointed expert reports on financial matters, particularly where the methodology is sound and no credible technical challenge has been raised.
A party seeking to challenge expert findings has two main routes. First, the formal written objection procedure within the allowed period after the report is filed. Second, introducing a party-commissioned expert report that specifically addresses the methodology and conclusions of the court-appointed expert. Courts consider both if properly submitted.
A common error is disputing expert findings in general terms, without engaging with the specific methodology or identifying specific figures that are contested. Courts expect objections to be technical, specific, and supported by evidence. A general assertion that the report is incorrect carries very little weight.
Practical Considerations for Parties
Prepare financial documentation before the expert is appointed. The expert examines what is produced. Disorganised or incomplete records produce an expert report based on incomplete information. Parties who present well-organised, complete financial records generally produce more favourable findings.
Engage at the objection stage, not after judgment. The formal objection period is the moment to raise technical challenges. Post-judgment challenges to expert findings are procedurally difficult and rarely succeed on their merits.
In large or complex disputes, a party-commissioned expert who reviews the court expert's report and prepares a technical objection provides substantially more persuasive support than a lay objection. The court-appointed expert may be required to respond to that technical objection, and the exchange creates a more complete factual record for the judge.
What a Court Reads First in an Expert Report
Article 117 of Federal Decree-Law No. 35 of 2022 sets what the report must contain: the task, the statements of the parties, the documents, the technical analysis, and reasoned findings, with any dissent recorded. The report is then read by a judge who is not an accountant. What that judge looks for is whether each question in the appointment order has been answered, and whether the answer can be followed from the documents to the figure without the reader having to take anything on trust.
In practice the reading order is consistent. The judge checks the restatement of the mandate against the order, to see whether the expert has answered the questions asked and only those questions. Then the list of documents examined, which shows what the analysis rests on and, by omission, what it does not. Then the methodology, which has to be named and justified rather than assumed. Then the calculation, which has to be reproducible from the schedules. Then the answer to each question, stated separately. Then any reservation the expert has recorded, which is where an incomplete document set or an unreconciled account is disclosed.
A report that is strong on narrative and thin on schedules is harder for a court to adopt, because there is nothing to check. A report that states a figure without showing the movement from the source records to that figure invites the objection that the figure is the expert's assertion rather than the record's.
How a Technical Objection Is Framed
The comment window on the initial report is the stage at which a challenge is heard on its merits. An effective objection has four parts, and the omission of any one of them is what usually causes an objection to fail.
Identify the question. Objections are made against a specific question in the appointment order, not against the report as a whole. An objection that does not say which finding is disputed leaves the court to guess.
Identify the document or the figure. The objection names the document that was not considered, the document that was misread, or the figure that does not follow from the schedules. A reference the court can open is worth more than a paragraph of characterisation.
Separate methodology from arithmetic. These are different objections with different remedies. An arithmetic objection is capable of being resolved by the expert on a referral back. A methodology objection asks the court to accept that a recognised alternative approach was the appropriate one in these circumstances, and it has to explain why, not merely assert it.
State the alternative figure. An objection that says the number is wrong without saying what the number should be, and how it was derived, leaves the court with only one computed answer on the file.
Article 119(2) sets the exchange that makes an objection worth making: the initial report goes to the parties, who have at least three business days to comment, the expert replies within five, and the final report is filed with the case management office. Article 119(3) admits objections raised after that filing only where they are novel, which is why the comment window matters. Article 121 then gives the court its options: it may question the expert, allow the parties to discuss him, order the report completed or corrected, or appoint another expert. Article 122(2) states the principle that governs the outcome, that the expert's opinion does not bind the court, which must give its reasons where it departs from it.
The Same Question in Arbitration
Where the contract provides for arbitration, the mechanism differs but the discipline does not. Under Article 34 of Federal Law No. 6 of 2018 on Arbitration, the arbitral tribunal may appoint one or more experts to report on specific issues it determines, and the parties are required to give the expert the information and access to the documents and property the assignment needs.
The practical differences are timing and scope. Parties in arbitration have more influence over when the expert is instructed, how the questions are framed, and the timetable for the report. That influence is worth using: questions drafted with care at the outset avoid the situation where the report answers something adjacent to the issue that decides the case. Reports prepared for a tribunal are also more often exchanged and tested between experts before the hearing, which narrows the disagreement to the points that genuinely divide them.
Documents, and the Weight They Carry
Both the court expert and the party expert work from what the parties produce, and the Evidence Law gives a party a route to what it does not hold. Articles 33 and 34 of Federal Decree-Law No. 35 of 2022 allow a party to ask the court to order its opponent to produce a document, and where the opponent refuses, the applicant's copy may be taken as true or the applicant's description of the document accepted. Article 35 goes further in commercial cases, where a refusal may be treated as a presumption that the claim is true. Article 36 allows the court to order a third party or a public body to produce documents or information. Article 37 leaves the assessment of defects in an instrument to the court, and Articles 53 to 63 deal with electronic records and electronic evidence and their probative value.
The consequence for a party is direct. Accounting records kept properly and contemporaneously are a different class of material from a reconstruction prepared once the dispute had started. Where the two conflict, the expert reports the conflict, and the court is left to weigh a contemporaneous record against a later explanation. That is rarely the position a party wants to be in.
Preparing Before the Appointment
The window in which a party can still improve its position closes when the appointment order issues. Before that point, the practical work is to reconcile the ledger to the bank for the whole period in dispute, locate the contracts, board approvals, and correspondence that support each disputed figure, and assemble the set in a form the expert can follow. After that point, the expert examines what exists.
Two further steps repay the cost in matters of any size. Read the appointment order when it issues, because a task that omits the question your case depends on is a problem that can be raised then and is very difficult to raise later. And have the initial report reviewed technically inside the comment window Article 119(2) provides, because that is the stage at which the analysis itself is open to challenge.
