Advanced Filter Search You can use a filter more than once. If you want to find a law firm ranked both in Banking and in Litigation, for instance, use the ‘Area of Law’ filter twice. For a law firm ranked in, say, France and Germany, use the ‘Location’ filter twice. For a lawyer with expertise, say, in Chemicals and in Real Estate, use the ‘Industry Sector’ filter twice. In fact, use a filter as many times as you like, reducing the number of results each time. Foreign Experts Foreign Experts are lawyers and law firms with expertise in more than one country. If you want to find a lawyer based in London with expertise in France, for instance, use ‘Town’ (choosing London).and ‘With Expertise in Another Jurisdiction’ (choosing France). You can then add other filters to narrow your selection further.
