What Kuri Breña, Sánchez Ugarte y Aznar does

Kuri Breña, Sánchez Ugarte y Aznar (KSA) is a full-service Mexican law firm organized as a civil partnership (S.C.) under Mexican law and headquartered at Prol. Paseo de la Reforma 1015, Torre B, Piso 8, in the Santa Fe business district of Mexico City. Founded in 1990 by a group of experienced Mexican lawyers, KSA operates across 15 specialized practice areas including corporate law, mergers and acquisitions, banking and finance, capital markets, tax advisory and controversy, competition law, energy and infrastructure, fintech, real estate, foreign investment, administrative litigation, arbitration and alternative dispute resolution, public procurement and compliance, and telecommunications. The firm reports a client portfolio of 576 national companies and 500 multinational/foreign companies, drawn from the Americas, Europe, and Asia, and has been recognized in major legal directories including Chambers Latin America, Legal 500, IFLR1000, Latin Lawyer, and Who's Who Legal across 2023–2025. KSA is also authorized by the Prime Certification Committee — developed jointly by AMIB, BIVA, Grupo BMV, Nafin, and Bancomext — to advise companies seeking Prime corporate governance certification.

The firm generates revenue through professional services fees, structured on hourly rates, fixed fees, or matter-based engagements typical of full-service legal advisory practices. There is no disclosed proprietary technology platform; service delivery is built on partner-led client relationships and senior practitioner expertise, with the firm operating exclusively from its Mexico City office and serving cross-border clients through direct engagement. Distribution is entirely direct: no resellers, marketplaces, or self-serve channels. The firm's marketing is anchored by thought-leadership content via an Insights/News section on its website, LinkedIn/Facebook/Instagram presence, and sustained recognition in premier global legal directories that drive inbound enterprise inquiries. No revenue, headcount, or ownership details are publicly disclosed, which is typical for a private Mexican partnership.
