Corporate and M&A Tier 2

Philippi Prietocarrizosa Ferrero DU & Uria is an excellent choice for cross-border Latin American deals due to its genuinely streamlined offices in Chile and Colombia. By way of illustration, it acted for power infrastructure business Transelec Group, a conglomerate present in Chile and Peru, on its acquisition of 100% of the outstanding stock in Compañía Transmisora Norperuana. The advice was led by Rafael Boisset, co-head of the practice, who is particularly experienced in transactions across the mining, transportation, construction, energy and financial sectors. Fellow co-head Guillermo Ferrero is widely respected for his expertise in cross-border deals and complex reorganisations. Other individuals to highlight include Javier Ezeta, who has in-house experience in the industrial sector, and principal associates Víctor Abad and Raúl Vizcarra, both regulars on key deal teams. Former name partner Jose Delmar departed in January 2020 to open his own law firm, LegalCorp.


Philippi Prietocarrizosa Ferrero DU & Uria  has been engaged by us since 2018 for corporate matters and M&A transactions, including amendment of company articles and compliance matters in relation to the Covid-19 outbreak. The firm has extensive experience in advising in corporate and M&A and its responsible team members are accessible around-the-clock, given the time zone difference of our locations. It has done an excellent job in helping the company assess and mitigate the relevant legal risks in association with our recent acquisition by means of bridging the gap between the parties in both cultural and legal perspectives. They demonstrated unique strengths in understanding our objectives, operations and practices. They never failed to meet tight schedules and milestones.’

Our main contact was Rafael Boisset, who is committed to enabling the smooth progress of the acquisition and going the extra mile to solve the unexpected legal issues which popped up during the execution stage of the acquisition.’

Senior associate Romina Stucchi joined the firm in June 2019 from government economic body FONAFE and focuses on the corporate and financing side of the sector.


As an internal lawyer, I need to be sure that there is a complete management of the business logic of our company, in order to receive optimal and comprehensive legal advice when requested. The team at Philippi Prietocarrizosa Ferrero DU & Uria has experience and knowledge of the sector and competes positively with teams from other law firms with which we also work.’

Carolina de Trazegnies manages the energy area, and highlights her knowledge of the sector and previous experience as a lawyer at OSINERGMIN. Marco Castañeda, who works in the team with Carolina, also stands out for his knowledge of the sector and his specialised master’s degree in the subject and has complemented the team in an ideal way with his previous knowledge and experience.’

The quality of the lawyers is excellent, in particular Carolina de Trazegnies. She has a deep technical knowledge of energy issues and the ability to explain it. She has excellent command of the English language. The firm’s customer service is impeccable and their response times too.’

Carolina de Trazegnies has much more mastery of energy issues than other attorneys from other firms with whom we have had an opportunity to work. In addition to her knowledge, Carolina is fluent in international litigation (particularly arbitration) being able to advise comprehensively in energy-related litigation. She is meticulous in her work and always ready to receive feedback. She is the best lawyer we have had the opportunity to work with in Peru.’

The firm has high knowledge of electrical regulations and related mergers and acquisitions. Very good internal coordination between the lawyers, which makes the quality of the service comparatively better than other firms in Peru.’

They have an important capacity for analysis and diagnosis that transmits confidence to the client. Competitors are generally less accurate than Philippi Prietocarrizosa Ferrero DU & Uria in their analysis and diagnosis. The firm has a high ability to track issues. Among the outstanding lawyers I can mention are Rafael Boisset and Romina Stucchi.’

An impressive client list at Philippi Prietocarrizosa Ferrero DU & Uria is testament to the solid and capable practice at the firm, which represents the likes of Graña y Montero, Lima Airport Partners (LAP) and Mondelez Perú.
