Investigating Lawyers in Mexico City, Instructed Worldwide
Warden Consulting is a corporate investigations and due diligence firm. Our investigating lawyers, forensic accountants and licensed investigators work from the World Trade Center in Mexico City and take instructions in all 32 Mexican states. The firm was founded in Auckland in 1995 and has since run investigations in more than 25 countries.
We act for international law firms and in-house counsel, multinationals in mining, technology and finance, investors, lenders and individuals who have lost money to fraud. Clients come to us when a decision depends on facts that a database cannot supply, and when the answer has to stand up to a board, a court or a regulator.
What We Do
Every matter is scoped in writing and priced before work starts, supervised by an investigating lawyer, and reported in English with the Spanish originals attached.
