Expert Witness for DIFC and DIAC
Expert Witness for DIFC Courts proceedings and DIAC (Dubai International Arbitration Centre) arbitrations, delivering common-law standard expert evidence on construction disputes.
The Dubai International Financial Centre (DIFC) Courts operate as an independent, English-language common law judiciary within Dubai, hearing civil and commercial disputes — including a substantial volume of construction and infrastructure claims — where the contract designates DIFC jurisdiction or where there is a sufficient nexus, such as a contract performed within the DIFC.
The DIFC Dispute Resolution Landscape
Since Decree No. 34 of 2021, the DIFC has also become the default seat of arbitration under the DIAC Rules 2022 where parties have not otherwise agreed — a significant shift from the previous default of Dubai (outside the DIFC). This means DIFC now functions as both a court system in its own right and the default seat for a large share of Dubai's institutional arbitration, giving it an outsized role in how UAE construction disputes are ultimately resolved.
Cross-jurisdictional enforcement has also been substantially strengthened: Cabinet Resolution No. 33 of 2023 clarified and streamlined the recognition and enforcement of DIFC Court judgments, reducing a historic source of friction and delay for parties needing to enforce a DIFC judgment or award against onshore assets.
Why the DIFC Matters for Construction Disputes
DIFC Courts apply English common law principles and conduct proceedings in English, with case management procedures and evidentiary practice — including a well-developed approach to expert evidence and cross-examination — that will feel familiar to internationally trained construction lawyers and experts. This makes the DIFC an attractive forum for complex, technically dense construction and quantum disputes involving international parties, where the depth of expert evidentiary practice available elsewhere may be less developed.
Expert Evidence Under RDC Part 31
Expert evidence in the DIFC Courts is governed by Part 31 of the Rules of the DIFC Courts (RDC), which also directs parties and experts to the Protocol for the Instruction of Experts to give evidence in civil claims, reproduced at Schedule A to that Part. The Court expects both legal practitioners and experts to have read the Protocol.
- Overriding duty to the Court (RDC 31.3–31.6): the expert's duty to help the Court overrides any obligation to the instructing or paying party, and the expert must not assume the role of an advocate.
- Permission required (RDC 31.12–31.16): no party may call an expert or put in an expert's report without the Court's permission, normally sought at the Case Management Conference and granted only for the named expert or identified field.
- Report contents (RDC 31.51–31.56): the report is addressed to the Court, states the substance of all material instructions, summarises any range of opinion with reasons, and contains a summary of conclusions and any necessary qualification.
- Written questions (RDC 31.24–31.28): may be put once only, within 28 days of service of the report, and for clarification only; the answers form part of the report.
- Court-appointed experts (RDC 31.29–31.47): the Court may appoint independent experts on designated issues, with parties able to respond within 28 days and use the report at trial.
- Concurrent expert evidence (RDC 31.48): the Court may direct that opposing experts be sworn and give evidence together as a panel, each with a short opening statement of up to 10 minutes.
- Experts' discussions and joint statements (RDC 31.58–31.64): experts identify agreed and disagreed issues with reasons; any agreement between experts does not bind the parties unless they expressly agree to be bound.
- Costs control (RDC 31.18): the Court may limit the expert fees and expenses recoverable from another party.
- Assessors (RDC 31.70 onwards): the Court may also appoint an Assessor under Article 18 of the Court Law to assist on matters within the Assessor's skill and experience.
DIAC — Dubai International Arbitration Centre
We also act as expert witnesses in arbitrations administered by the Dubai International Arbitration Centre (DIAC), the UAE's largest arbitral institution. Under the DIAC Arbitration Rules 2022, the DIFC is the default seat absent contrary agreement, so DIAC arbitration and DIFC Court supervision routinely operate together on the same construction dispute.
- Quantum, delay, defects and structural expert reports prepared for DIAC tribunals under the DIAC Rules 2022.
- Experience with DIAC's expedited procedure, consolidation and joinder provisions on multi-contract construction projects.
- Expert conferencing, joint statements and cross-examination before DIAC tribunals seated in the DIFC or Dubai (outside the DIFC).

Frequently Asked Questions
- Do you act as an expert witness in DIAC (Dubai International Arbitration Centre) arbitrations?
- Yes. We regularly act as quantum, delay, defects and structural expert witnesses in arbitrations administered by DIAC, the UAE's largest arbitral institution. Reports are prepared under the DIAC Arbitration Rules 2022 and to IBA Rules and CIArb Protocol standards, and our experts attend procedural hearings, expert conferencing and cross-examination before DIAC tribunals.
- How do DIFC Court proceedings and DIAC arbitration interact?
- Under the DIAC Arbitration Rules 2022, the DIFC is the default seat of arbitration where the parties have not agreed otherwise, so the DIFC Courts frequently exercise supervisory jurisdiction over DIAC arbitrations. Expert evidence therefore needs to satisfy both DIFC common-law evidential expectations and DIAC tribunal practice, which is how we prepare every report for Dubai-seated matters.
- What standards govern the conduct of an Expert Witness for DIFC Court proceedings?
- Expert evidence before the DIFC Courts is governed by Part 31 of the Rules of the DIFC Courts (RDC). Under RDC 31.3 to 31.6 the expert's overriding duty is to help the Court on matters within his expertise, and that duty overrides any obligation to the instructing or paying party. Evidence must be the independent product of the expert, objective and unbiased, and the expert must not assume the role of an advocate. RDC 31.2 also directs parties and experts to the Protocol for the Instruction of Experts to give evidence in civil claims, reproduced at Schedule A to Part 31.
- Does a party need the Court's permission to rely on an expert in the DIFC Courts?
- Yes. Under RDC 31.13 no party may call an expert or put in evidence an expert's report without the Court's permission, and RDC 31.12 restricts expert evidence to what is reasonably required to resolve the proceedings. The application is normally made at the Case Management Conference (RDC 31.14) and must identify the field of expertise and, where practicable, the named expert (RDC 31.15). Permission is granted only for that named expert or identified field, and the Court may also cap the recoverable expert fees under RDC 31.18.
- Why is the common-law background significant for an Expert Witness for DIFC?
- The DIFC Courts operate under a common-law framework, differing from the UAE's civil law system. An Expert Witness for DIFC must understand cross-examination procedures and the duties imposed by RDC Part 31, including the requirement in RDC 31.52 that the report is addressed to the Court rather than to the instructing party. Reports must be structured to assist a common-law judge in interpreting complex technical data regarding quantum, delay or engineering defects.
- How are written questions to experts handled under the DIFC Rules?
- Under RDC 31.24 a party may put written questions to an expert instructed by another party or to a Court-appointed expert. Those questions may be put once only, must be served within 28 days of service of the report, and must be for the purpose of clarification only, unless the Court gives permission or the instructing party agrees (RDC 31.25). The answers form part of the expert's report (RDC 31.27), and if the expert fails to answer, the Court may bar reliance on that evidence or refuse recovery of the expert's fees (RDC 31.28).
- Can the DIFC Court appoint its own expert or order concurrent expert evidence?
- Yes. Under RDC 31.29 the Court may appoint one or more independent experts to report on specific designated issues; that expert may request information, documents or site access from the parties (RDC 31.34), the report is sent to the parties, and any party may respond within 28 days and use the report as evidence at trial (RDC 31.41 to 31.43). The Court may also direct concurrent expert evidence — hot-tubbing — under RDC 31.48, with experts sworn together as a panel and each permitted a short opening statement of up to 10 minutes.
- What must an expert's report contain in DIFC Court proceedings?
- RDC 31.51 to 31.56 set out the required contents. The report is addressed to the Court, must state the substance of all material instructions (written or oral), make clear which facts are within the expert's own direct knowledge, identify who carried out any test or examination and their qualifications, summarise any range of opinion with reasons for the expert's own view, contain a summary of conclusions, and state any qualification where the expert cannot give an unqualified opinion. Where the expert cannot confirm the report contains the truth without qualification, that qualification must be stated (RDC 31.10).
- What happens when DIFC experts meet and agree issues?
- The Court may direct experts to discuss the issues, and may specify the issues to be discussed (RDC 31.58 to 31.59). The experts then produce a joint statement recording the issues on which they agree, those on which they disagree, and a brief summary of the reasons for disagreement. Importantly, under RDC 31.64 any agreement reached between the experts does not bind the parties unless the parties expressly agree to be bound by it.
- Can an Expert Witness for DIFC assist in both litigation and seated arbitrations?
- Yes. An Expert Witness for DIFC is frequently instructed in litigation before the DIFC Courts and in arbitrations seated in the DIFC. Whether operating under DIAC or ICC rules, the expert provides technical clarity on FIDIC contract applications, ensuring that the evidence remains credible and withstands rigorous scrutiny during oral testimony.
- Where does the Expert Witness for DIFC document their findings on quantum?
- The Expert Witness for DIFC documents their findings in a written report addressed to the Court, since RDC 31.20 requires expert evidence to be given in a written report unless the Court directs otherwise. This includes detailed schedules of loss, valuations of variations under FIDIC forms, and assessments of liquidated damages. Copies of the photographs, plans, analyses, measurements, survey reports and unpublished sources relied on must be provided to all parties at the same time as the report (RDC 31.21), and where the expert cannot confirm the report contains the truth without qualification, that qualification must be stated (RDC 31.10).
- When should a developer or contractor instruct an Expert Witness for DIFC?
- Parties should engage an Expert Witness for DIFC as soon as a dispute appears likely to reach the DIFC Courts. Early involvement allows the expert to review project data, identify strengths or weaknesses in the technical position, and provide a preliminary assessment that informs the legal strategy for the subsequent litigation or arbitration.
- If a conflict of interest arises, how must the Expert Witness for DIFC respond?
- An Expert Witness for DIFC is mandated to disclose any potential conflict of interest immediately to all parties and the Court. Maintaining absolute impartiality is paramount; if a conflict compromises their independence, the expert must decline the instruction. Related duties apply where an expert's position changes: under RDC 31.11, if after producing a report the expert changes his view on any material matter, that change must be communicated to all parties without delay and, where appropriate, to the Court. An expert may also apply to the Court for directions under RDC 31.66.
