Our firm, founded in 1981, relies on a team of professionals highly specialized in the different areas of law and thoroughly familiar with the economic sectors in which they work, which makes our legal services fit perfectly with our clients’ business strategies. We are the only firm in Peru with nationwide coverage through a vast network of offices, which makes us offer high quality services in almost every city in Peru. Our lawyers’ international experience is highly appreciated by our clients in the context of integration with the rest of the world.

We have more than 35 practice areas, offering a high standard of quality services, with specialized professionals for each area, competitive pricing and a timely service. Thanks to the combination of these three factors, our clients are really satisfied with the service we provide, which in turn allows us to build long-lasting relationships.

We designate one account lawyer for each client. This lawyer, whom we call “Attache”, is in charge of looking after the client-firm relationship and proposing the most efficient and cost-effective strategy for each case, transaction or task entrusted to us. If more than one practice group needs to become involved in a case, then the Attache will be in charge of setting up the most appropriate team of lawyers to deal with the case.

Our firm was the first, and probably still the only one, with a quality control customer service department. This department is in charge of staying in contact with clients to know how satisfied they are with the service. Team members permanently work on ways to improve relationships with clients.

The firm has deeply diversified its offer. There is Muniz Transfer Pricing, a sister entity devoted to transfer pricing and Semigra, a company that provides a migration consultancy. Recently the firm has set up an alliance with Intedya, a well known Spanish company with a presence in 16 countries and which is focused on implementing compliance programs to several companies, and with Contalex, a provider of accounting services.
