Firm Overview:
Guyer & Regules is considered Uruguay’s blue-chip firm and the first choice for international and domestic complex legal, accounting and tax work. Such reputation is grounded on the largest group of the most experienced partners in the country, who lead a solid team of internationally trained professionals with experts in every field of business law, and promote a culture of innovation within the firm. Guyer & Regules is proud to have been consistently recognised as “Uruguayan Law Firm of the Year” for nine years and the first and only Uruguayan firm recognised as “Latin America Law firm of the Year” by Chambers and Partners.

Performing with excellence, expertise, value, responsiveness, creativity and consistency, is not enough. At Guyer & Regules we strive to grow our capacity to develop strong and mutually rewarding personal working relationships with the people who work at the institutions we serve. We help them serve their institutions – our clients – better. And those special personal working relationships are what enable us to leverage all those other qualities they expect from a top firm. The Guyer way of serving also implies embracing diversity, cultivating inclusion and promoting environmental stewardship. We have a strong vocation for service rooted in our DNA and this is reflected in our long history providing pro bono with the level of excellence that defines Guyer & Regules. As a result of this, in 2023 we were recognised as Pro Bono Firm of the Year by Latin Lawyer.
