Santiago Castellán plays an active role in the team, representing both companies and creditors in financial restructurings and insolvency proceedings. Senior associate Carolina Diaz de Armas joined the team in August 2023, strengthening its cross-border capabilities and advising on international contractual matters.

Legal 500 Editorial commentary

Testimonials

Collated independently by Legal 500 research team.

  • ‘Castellán's litigation team is very balanced. It is led by Lucía Acosta, who is not only technically excellent, but has an enormous ability to identify the true needs that clients have and translate this into the strategy. She works very closely with young, creative and very tenacious lawyers, and also has the support of external consultants in different innovative practice areas (such as technology), which guarantee the constant updating and also provide a fresh vision to the team. For those of us who work in non-traditional industries, this is a great support.’

  • ‘The strong interaction between the different practice areas, and the team feeling they convey really makes us clients think that "all fronts" are covered. Lucia Acosta is exceptional. She has always had great lucidity for strategy, she is innovative and extremely versatile, and she works with great ease in different areas and complex situations: it should be noted that she is conciliatory by nature but also relentless when she must be. What I value most about working with Castellán and the team is the deep knowledge of the client they have. I always feel like they are "one more" of my company's team, and that is not easy to see in the market.’

  • ‘The team offers an overall legal approach for business, able to cover the main relevant legal aspects in Uruguay and most of the Latin American countries.’

  • ‘The individuals are highly qualified and strongly focused on the clients' needs.’
