History
In 1974, in the heart of El Salvador, Valdivieso & Asociados was founded with a clear vision: to provide outstanding legal counsel to public and private entities, with a strong focus on the corporate sector. From its inception, the firm distinguished itself through its unwavering commitment to ethics, professionalism, and client dedication.
As El Salvador and Central America underwent economic and social transformations, Valdivieso & Asociados adapted and grew, anticipating the needs of an ever-evolving market. Recognizing the importance of regional integration and global opportunities, the firm became a pioneer in establishing international connections, advising companies on transactions spanning Central America, the United States, Mexico, and Europe.


The firm’s strategic vision led it to join LEGIC GROUP, an alliance that brings together five renowned firms across Central America. This collaboration not only expanded the firm’s geographic presence but also strengthened its ability to deliver comprehensive legal solutions with a consistent standard of quality throughout the region. Furthermore, its expansion into Asian markets, with operations in Hong Kong, reflects its commitment to staying at the forefront and facilitating opportunities between Latin America and Asia.
The leadership of distinguished figures such as José Mario Valdivieso Berdugo has been instrumental in this journey. Since 1992, his direction in the corporate and dispute resolution departments has guided countless clients in identifying and capitalizing on business opportunities, solidifying the firm’s reputation as a strategic partner in the legal field.
Today, with nearly five decades of experience and a multidisciplinary team of more than 50 attorneys across the region, LEGIC El Salvador continues its legacy of excellence. Its active membership in various binational chambers of commerce and participation in international organizations underscore its commitment to business development and the promotion of investment in El Salvador and beyond.
The story of LEGIC El Salvador is a testament to perseverance, adaptability, and vision. From its humble beginnings to becoming a leading law firm in the region, its journey inspires confidence and reflects an unwavering dedication to excellence and client service.
