Muñiz Olaya Melendez Castro Ono & Herrera Abogados

Rankings and analyzes


Muñiz, Olaya, Meléndez, Castro, Ono & Herrera is a leading law firm in Peru and Latin America  thanks to its philosophy which focuses on offering high-quality services in a timely fashion and at competitive prices.  

Since it was founded 40 years ago, Muñiz has had a Litigation Practice Group which provides counsel and defends clients in civil, commercial, contentious-administrative and constitutional law proceedings brought with the Judiciary and, in the latter case, with the Constitutional Court. The strength of this practice group lies in the high professional skills of its lawyers, their experience in handling highly complex cases, and their knowledge of Peru’s procedural system. In addition, if so required to properly defend a client, a team composed of trial lawyers and lawyers specializing in the subject matter of the dispute, for instance, tax law, the stock market, insurance law, etc.,is set up.

These same features also make our Arbitration Practice Group stand out, as its lawyers are highly qualified to provide advice to and represent our clients in arbitration proceedings carried out under the regulations of Peruvian arbitration centers and other centers all over the world, including ICC, ICSID, and UNCITRAL. Our services also include advice on the annulment, acknowledgement and enforcement of arbitration awards, filing of applications for injunctive relief, negotiation of arbitration clauses, and protection of foreign investment within the framework of bilateral investment protection and free trade agreements signed by Peru.
