RATIO LEGIS is a dynamic, full-service law firm with roots tracing back to 1950 through its predecessor, Barrero & Asoc., founded by Dr. Miguel Barrero Barrientos in Sucre, Bolivia—the nation's judicial capital. The firm was transformed and established under the name RATIO LEGIS in 2003, carrying forward a legacy of deep legal and public service, notably from its predecessor, Dr. Rafael Barrero Martínez (La Paz), who held high-ranking positions in the Republic of Bolivia.

In 2013, RATIO LEGIS expanded its operations to Paraguay, creating a strategic bilateral legal hub. This expansion was driven by the clear objective of facilitating international investment and business between the two countries, positioning the firm as a key legal reference for compliance, security, and risk management for all parties involved in commercial transactions.
