International arbitration lawyer. Represents corporations and financial institutions worldwide. Recognized for Middle Eastern arbitrations. Fluent in Arabic and French. Dual qualified - US/UK.

Practice Description

Samaa Haridi’s practice focuses on complex international litigation and arbitration proceedings involving joint ventures, international investments, service agreements, construction projects, contracts, banking, and securities.

Ms. Haridi has extensive experience representing parties in proceedings under the arbitration rules of the International Centre for Settlement of Investment Disputes (ICSID), the International Chamber of Commerce (ICC), the International Centre for Dispute Resolution (AAA/ICDR), the London Court of International Arbitration (LCIA), and the United Nations Commission on International Trade Law (UNCITRAL).

Her arbitration work breaks down roughly evenly between commercial arbitrations and investor-state arbitrations.

Samaa began her legal career in Los Angeles as a litigation associate, and moved into international dispute resolution after working on some large global disputes early on in her career. She then developed a particular focus on international arbitration. In addition, Samaa handles some arbitration-related litigation, and a smaller amount of regular commercial litigation.

Industry sector expertise

Samaa has acquired a concentration of experience in several important industry sectors, typically ones where arbitration is more common. They include construction, the hotel and hospitality sector, oil and gas, and the chemical industry.

Overseas expertise

Samaa Haridi is the quintessential international lawyer. Born in Switzerland, her father was a diplomat and while growing up she spent several years in each of Belgium, Egypt, Morocco, and France.

After graduating from the Cairo branch of the University of Paris, Samaa was awarded a scholarship to pursue her studies at the Sorbonne University in Paris, France. She moved to the United States in 1999 to continue her legal studies, and first practiced as a lawyer in Los Angeles.

Now based in New York, she represents clients from the United States, Europe, the Middle East, Latin America, and Asia in all the main international arbitration forums. Samaa is recognized for Middle Eastern arbitrations and her fluency in Arabic and French are an added draw for clients seeking commercial and investment treaty arbitration expertise in these parts of the world. Specific countries where she has developed expertise include Egypt, the UAE, Oman, Saudi Arabia, Qatar and Lebanon.

A dual-qualified US-UK lawyer, Samaa is admitted to practice in the U.S. in the states of New York and California, and is also an English solicitor. She has acquired exposure to both the common and civil law systems throughout her career.
