CMS Grau is 'very specialised in this area’ and fields a 'strong team’ spearheaded by Michelle Barclay (highlighted for her international experience and 'business vision’), and very capable counsel Victor Farro (praised for his legal knowledge, litigious skills and 'practical solutions’). The firm has been advising on some of the country's largest bankruptcy cases in recent years, including Doe Run (acting for strategic creditor Depósitos Químicos Mineros), and China Fisheries, the latter case illustrating Barclay's expertise in US Chapter 11 bankruptcies, where she is acting for trustee Willam Brandt. Other key members of the team include associates Carolina Pinzás and Miguel Viale, who are also both advising in the China Fisheries case.

Practice head(s):


I have been working with the CMS Grau team on bankruptcy issues since 2016. They have a very strong team and a significant number of lawyers who have a lot of experience, both locally and internationally (which differentiates them from other various firms). Our company, both our team from Peru and Spain, consider that this expertise for international clients and processes has helped us a lot as a company in the strategy of our cases. Currently, we have started one of the largest bankruptcy processes in Peru and we have been receiving excellent and high-quality advice from the CMS Grau team, mainly from Michelle Barclay (partner) and Victor Farro (senior associate). I feel very well supported by the team and I consider that unlike other law firms, they handle a variety of highly-complex issues that are related to other areas of law (such as tax, corporate, infrastructure, arbitration) which makes the service much more complete. The vision of the leaders of the team is comprehensive and strategic.’

Michelle Barclay has a lot of international experience, since she has worked in New York in the bankruptcy team of ​​Skadden, Arps, Slate, Meagher & Flom LLP, and that allows her to provide us with different advice than what we could receive from other firms. Also, Michelle is characterised by her very quick understanding of the client’s problems, by her clear answers and business vision. Victor Farro has a holistic view of the market, extensive knowledge of the law and the ability to design strategies and propose practical solutions. He stands out for his talent for litigation, his analytical capacity and the clarity with which he supports the positions that he has to defend, both verbally and in writing. He is a key part of the CMS Grau team.

The practice is very specialised in this area. The lawyers who handle this work have to be very aware of all the changes and/or modifications that are dictated in this field and the team at CMS Grau are very experienced in the subject and have been since practically the beginning of this legislation in the 1990s. It is very difficult to make comparisons, but I think CMS Grau has one of the best teams in this area.

Timely and professional support to the client. It is a multidisciplinary team that is very close to the client. It compares favourably to the standard of the top market segment.’

Warm treatment and professional strength. Its best qualities are successful analysis and precision in implementation. Michelle Barclay and Victor Farro stand out.

Good team that responds quickly to requests from the client. The work they did was of high quality.

Both Michelle Barclay and Carolina Pinzás provided us with a high quality service.

I highlight their profound knowledge of bankruptcy and restructuring, and their ability to sort through the issues quickly. Their desire to help and take the issues where the client wants to go is their strong point.’

Their expertise in financial matters, added to their vision in corporate matters, means that clients receive complete advice on issues.’

Miguel Viale is the senior lawyer of CMS Grau who mainly interacts with us. He has vast experience in financial operations, particularly in trusts as well as in corporate matters. The holistic vision and creativity that the firm imparts allow for solutions according to the client’s needs.’

CMS Grau provides top-quality services and legal advice. They know that it is important for us to receive immediate and substantial attention.
