Payet, Rey, Cauvi, Pérez Abogados

In a remarkable coup, Payet, Rey, Cauvi, Pérez Abogados hired virtually the entirety of CMS Grau‘s mining team in October 2023, welcoming practice head Cecilia Gonzáles (corporate, M&A and regulatory matters pertaining to the natural resources and the extractive industries) and a group consisting of: Raúl Ferreryra (who brings corporate, IP, tax and real estate-side expertise to the practice); counsel Liliana Pautrat (who is active in the exploration, exploitation, processing and transport segments of the mining industry, and has a focus on regulatory matters); and four associates. They join a team which had already established a relevant footprint in the sector (particularly on the financing side) under the leadership of partner José Cúneo (with support from environmental specialist Vanessa Chávarry -who was raised to the partnership in December 2022- and counsel Ángel Chávez). While it remains to see how this significant group hire will settle at it new home, the combined group not only has capability in the transactional and financing aspects of the practice, but also expertise across areas including titling and real estate, environmental and social issues, administrative matters, regulatory compliance, project development and construction, and tax and labour issues; as such, it looks likely to boost the firm to key player-status in the sector.
