Work areas

This firm is highly recommended for services in the following work areas.

Bomchil – formerly M & M Bomchil – is a highbrow firm that boasts real prestige in the Argentine legal market and further afield. It has a high-quality, varied offering that clients value. The core areas here are corporate and M&A, banking and finance, administrative law and tax. Its disputes and telecoms practices are also ones to watch. Bomchil’s boutique-style practice areas, led by hands-on partners, allow the firm to build tailor-made teams to meet each client’s multidisciplinary needs.

Clients pile high praise on the firm, with one hailing its “deep legal knowledge, willingness to work side by side with the client, sophistication and understanding of legal problems”.

Bomchil helps foreign investors navigate the Argentine legal system in several areas. The firm has notably helped companies obtain contracts under Argentina’s first-ever public–private partnership bidding round, emphasising its strength in administrative law.

The firm has regained its shine in arbitration too – with partners like Federico Campolieti chairing several high-profile cases in Argentina.

Bomchil has also taken bold steps to make a name for its capital markets offering in 2020, winning roles on landmark deals involving airport operator Aeropuertos Argentina 2000 and energy company Compañía General de Combustibles.

As part of the firm’s strategy to expand its service offering, Bomchil poached three partners from oil and gas specialist law firm Alliani & Bruzzon – including esteemed partner Pablo Alliani in 2020 and, in January 2022, it bolted on Teijeiro & Ballone, a respected tax boutique. 

Meanwhile, Bomchil has implemented clear career track and retirement policies to safeguard its future. Of counsel agreements have also been made with several retired partners (including honorary president Máximo Bomchil), allowing the firm to continue its generational handover while benefiting from the experience of the senior generation. The firm’s leadership style is inclusive, and it prides itself on horizontal decision-making. Javier Petrantonio has been managing partner since 2011 – this is a position that is held for two years before a vote takes place. The other executive committee members are Alejandro MessineoMarcelo den Toom and Patricio Martin, who have made a big effort to uphold a collegial working environment that emphasises teamwork. Training programmes build lawyers’ skills in legal areas, as well as management and leadership.

The firm is keen to promote diversity in its ranks and regularly holds events at its offices to increase awareness and encourage discussion. María Inés Corrá plays a big part in the firm’s diversity activities and dedicates a large chunk of time to similar causes outside of her legal work. Bomchil’s partnership is more gender diverse than many of its competitors in Argentina and the firm is formalising policies that protect that status quo.

While Bomchil has made room for anticipated growth in the firm’s M&A, finance, bankruptcy, IP and compliance departments, it aims to strike a balance between attracting the best talent and avoiding overstaffing, so it approaches growth conservatively. This prudent strategy has paid off given the ups and downs of the Argentine economy and the downturn caused by the covid-19 pandemic.
