Dentons has pushed deeper into South America through a tie-up in both Argentina and Uruguay.

The firm has announced a combination with Argentinian firm Rattagan Macchiavello Arocena, based in Buenos Aires and Uruguayan firm with Jiménez de Aréchaga, Viana & Brause, based in Montevideo.

Rattagan Macchiavello Arocena, headed by Juan Martín Arocena has 13 partners and 40 lawyers while Jiménez de Aréchaga, Viana & Brause, headed by Fernando Jimenez de Arechaga, has eight partners and 40 lawyers. The latter is itself the product of the first law firm merger in Uruguay, between Jiménez de Aréchaga & Brause and Estudio Hector A. Viana in 2001.

Over the last year, Dentons has been hungrily expanding into South America. At the beginning of the year, it combined with a Venezuelan firm that was part of Norton Rose Fulbright, Despacho de Abogados miembros de Dentons in Caracas. Juan Carlos Pró-Rísquez, who became Norton Rose’s managing partner in Venezuela in 2018, now leads the office under its new name. Norton Rose put its departure from Venezuela, which is racked by hyperinflation and food shortages, down to “challenging market conditions.”

Last August, Dentons combined with Chilean firm Larrain Rencoret Urzua (LRU). Through the merger, Dentons laid down roots in Santiago, where LRU is based, and acquired 33 lawyers. It also opened offices in Nicaragua and El Salvador last year.

It has 23 offices throughout Latin America and the Caribbean, including in Guatemala, El Salvador, Panama, and San José and Guanacaste in Costa Rica.

In 2015 it joined forces with Colombia’s Cárdenas & Cárdenas, and Mexico’s López Velarde,

In May 2018, Dentons became the first global firm to enter Hawaii, following a merger with independent player Alston Hunt Floyd & Ing, which saw it add almost 50 lawyers to the firm’s US platform. Earlier in the summer, it encroached further into Africa through a proposed tie-up with Zimbabwean firm MawereSibanda.

The combinations with Rattagan Macchiavello Arocena and Jiménez de Aréchaga, Viana & Brause, following approval by partners and subject to meeting regulatory requirements, are expected to launch in the next several months.
