Latin Lawyer

Probably the most established corporate firm in Montevideo, blending tradition and experience with a modern approach – notably through substantial investment in leading-edge technology.


In a very young partnership for such an establish firm, Nicolás Herrera remains the most prominent name, alongside with Álvaro Tarabal, with Nicolás Piaggio also regularly mentioned. Like most firms in Montevideo, Guyer also employs a number of notaries and accountants, making it a considerably bigger organisation than the lawyers numbers suggest. In comparison to the other Uruguayan firms on this list, a notably high proportion of Guyer’s lawyers have worked or studied abroad, notably at associate level.


An impressive client list heavy with banking and multinational corporate names. One key banking client described Guyer’s lawyers as “outstanding professionals, who understand our business and our legal environment”.


Guyer is a member of the Club de Abogados, the Lex Mundi network and Multilaw.
