Corporate compliance is a core focus for Castellan Abogados, which advises clients on the implementation of internal policies, often on a multi-jurisdictional basis. International companies make up a significant proportion of the group’s client roster, spanning the real estate and construction, infrastructure, agribusiness, retail and automotive industries. The team has a successful track record advising on the incorporation of subsidiaries in the country and mergers by absorption. Share transfers, share purchase agreements and shareholder disputes are also areas of expertise. Practice head Santiago Castellán brings a strong background in M&A to the team. Maria Lucia Acosta leads the dedicated corporate compliance practice, spearheading the firm’s due diligence work and playing a key role in subsequent M&A. At the associate level, Mariana Fagioli joined the team in June 2023, bringing to the team corporate governance expertise and advising both local and foreign companies. María Paula Uhalde García left the firm in January 2024.
