One of Argentina’s leading financial services companies, Efectivo Sí is notable for its financial assistance to customers for the purchase of motor vehicles, utilities, trucks and agricultural machinery. The legal support of these arrangements is complex, and the company’s legal function relies on ‘effective collaboration and a deep knowledge of technical skills’ to achieve this, as described by a nominating source. Legal affairs coordinator Martin Caldas came in for particular praise from a private practice source, particularly for his work in the area of corporate regulatory advice.
