Muñiz, Olaya, Meléndez, Castro, Ono & Herrera, founded in 1981, has considerable professional experience and is the largest law office in Peru. Our firm tries to develop a solid commitment and a long-term relationship with its clients in order to become identified with their business objectives and offer the necessary professional support, coupled with experience, creativity and common sense.

Muñiz is a member of the Pacific Rim Advisory Council (PRAC), an organisation that groups together over 32 of the most important Pacific Rim law offices, and also joined the Ibero-American Compliance Practice Group, the Latin American Alliance Against Piracy and Counterfeiting (ALAF) and Interact Law.

The firm was the first law fim in Peru in opening a dedicated accounting service to meet the needs of companies and in view of the new criteria of the income tax law regarding the transfer-pricing regime, the firm also set up Muñiz Transfer Pricing. Furthermore, there is Semigra, a company that provides migration consultancy. Recently the firm set up an alliance with Intedya, a well-known Spanish company with presence in 16 countries which focuses on implementing compliance programs at several companies.

The firm was the first, and probably still the only one, with a quality control and customer services department. This department is in charge of staying in contact with clients to know how satisfied they were with the service they received.
