Uruguay > Corporate and M&A Tier 3

The ‘solid, efficient and proactive’ team at Castellan Abogados is well-versed in handling corporate governance issues and the local incorporation of foreign entities, negotiating commercial agreements, and advising on M&A. Clients operate in the real estate, construction, agribusiness, retail and automotive sectors, and appreciate the group’s ‘profound local knowledge’ and ability to ‘effortlessly deal with cross-border matters’. The ‘technically strong’ and ‘pragmatic dealmaker’ Santiago Castellán heads up the group and specialises in M&A, corporate governance and bankruptcy law. Lauded as ‘very talented’ and an ‘efficient communicator’, Maria Lucia Acosta was raised to the partnership in August 2023, becoming head of the disute resolution practice; on the corporate front, she provides key compliance and day-to-day corporate advice to companies. The practice was strengthened in July 2022 with the arrival of public notary María Paula Uhalde García, formerly at Ferrere.
