When an English court or UK-seated arbitral tribunal must decide a dispute involving Middle Eastern or Arab law, the legal question often becomes evidential. English law generally treats foreign law as a matter to be proved, not assumed, and foreign-law issues are commonly addressed through expert evidence before the English courts. Counsel are constantly on the lookout for experts such as Dr. Karim Youssef, a foreign-law expert who can explain the relevant law clearly and independently, and in a manner that genuinely assists the court or tribunal in resolving the issues before it, providing the English courts with far more than legal knowledge alone.
Why Dr. Karim Youssef’s Expert Testimony and Experience Before English Courts Matter
Foreign-law evidence in UK proceedings requires more than simply stating what the law says. It requires the expert to explain how the law operates in practice, including the manner in which it interacts with adjacent legal fields, how it may be applied by local courts or authorities, and where there may be room for interpretation.
Dr. Karim A. Youssef brings that combination of academic depth and practical experience. Educated at Yale Law School, Paris 1 Panthéon Sorbonne, and Cairo University, he has worked across international arbitration, investment treaty disputes, commercial disputes, and legal expert testimony involving Middle Eastern and Arab law. Chambers lists Dr. Youssef as a most in demand arbitrator and a Star Individual in Egypt Dispute Resolution: Arbitration and notes his work across major arbitration matters.
His work as a legal expert has covered a majority of Arab laws, including UAE, Saudi, Kuwaiti, Qatari, Bahraini, Omani, Lebanese, and Egyptian law, as well as issues involving Islamic Sharia. This matters for English counsel because cross-border disputes rarely involve one legal system in isolation.
A dispute before a English court may involve a Dubai-based commercial contract, a Saudi corporate structure, Kuwaiti regulatory issues, or Arab-law questions arising from family wealth, sovereign entities, infrastructure, or investment disputes. The expert must explain the local law and its commercial context without turning the report into advocacy.
Dr. Youssef has also been recognised by Lexology Index as a Global Elite Thought Leader, with listed expertise across Egyptian, Qatari, Kuwaiti, and Emirati law.
For counsel requiring expertise in both Middle Eastern law and UK arbitration, Dr. Youssef’s profile is particularly compelling because his experience sits at the intersection of Arab law, common-law procedure, and international arbitration practice.
What English Adjudicators Look for in a Foreign-Law Expert
A foreign law expert witness must satisfy a demanding standard. The court is not looking for a partisan explanation of the law. It needs evidence that is independent, impartial, structured, and useful for determining the legal question before it.
In practical terms, English courts and tribunals tend to look for four things:
Clarity: The report must explain the legal rule, the source of the rule, and how it applies to the facts. It should not overwhelm the court with unnecessary background.
Independence: Expert evidence is intended to assist the court or tribunal. Under CPR Part 35, an expert’s duty is to help the court on matters within their expertise, and that duty overrides any obligation to the party instructing or paying the expert.
Current practice knowledge: Middle Eastern and GCC laws can be affected by legislative reform, regulatory practice, ministerial decisions, and evolving court approaches. An expert must be able to explain not only the text of the law, but how it is understood in practice.
Comparative-law ability: English adjudicators often need the expert to bridge legal cultures. Before English tribunals, an Arab law expert may need to explain civil-law concepts, Sharia-informed principles, administrative-law questions, or public-policy issues in language that is accessible to common-law decision-makers.
This is why expert testimony on Middle Eastern law cannot be reduced to translation. It is a structured exercise in legal explanation.
How Youssef + Partners Supports Counsel in English Proceedings
At Youssef + Partners, the Legal Expert Testimony practice supports international counsel in disputes involving Middle Eastern, Arab, and GCC law.
The firm’s work includes matters involving:
- Commercial contracts
- Investment treaty claims
- Sovereign entities and state-owned companies
- Family wealth and HNWI disputes
- Shareholder, corporate, regulatory, and public-policy issues
The work usually begins with scoping. Counsel may need to know whether a foreign-law issue is material, whether expert evidence is required, and how the question should be framed. A precise question helps the court or tribunal understand what it is being asked to decide.
The next stage is the expert report itself. The report must identify the relevant law, explain the legal position, apply it to the facts, and address areas of uncertainty or competing interpretation. In English proceedings, this may also involve responding to another expert, preparing joint statements, and supporting counsel ahead of cross-examination.
The firm also supports counsel with cross-examination preparation, including identifying likely pressure points in the opposing expert’s report, clarifying technical foreign-law issues, and helping counsel frame questions around areas of disagreement. Practice Direction 35 recognises written questions to experts as part of the expert evidence process, reinforcing the need for clear, tested, and well-structured expert analysis.
For example, a UK-seated arbitration involving a Dubai infrastructure project may require expert evidence on termination rights, public procurement obligations, or the authority of a state-related entity. A family wealth dispute may require analysis of UAE, Saudi, Kuwaiti, or Egyptian law governing asset control, succession arrangements, or corporate ownership. In each case, the expert’s role is to clarify the law, not to argue the case.
That is the discipline behind English courts’ foreign-law evidence. The evidence must be accurate, independent, unbiased and usable by the adjudicator.
