About Mijares
Mijares, Angoitia, Cortés y Fuentes (“MACF”) is one of Mexico’s leading law firms, recognized for its excellence in corporate law, litigation, energy, and infrastructure. With a reputation for precision and elite client service, Mijares drives innovation to keep pace with evolving client expectations and market demands.
Opportunity
Mijares launched Harvey through a collaborative pilot and followed with a full-firm rollout. Adoption was driven by a blend of strategic internal leadership and grassroots momentum, including:
- Onboarding led by embedded “knowledge champions” across practice areas
- Ongoing internal communications highlighting wins and best practices
- Partner-level sponsorship to reinforce Harvey’s role in client service
This resulted in over 80% of MACF lawyers now engaging with the platform weekly. This change management approach built a culture where Harvey became central to both internal workflows and external client deliverables.
With Harvey, Mijares delivers higher-quality legal work at greater speed, enabling competitive pricing, faster turnaround, and greater capacity to take on more matters without increasing headcount. Lawyers report saving an average of six hours per week by streamlining critical workflows, including:
- Transactional Due Diligence: Mijares lawyers use Harvey to analyze large volumes of documents and surface key findings in clear, structured tables. This shift reduced review timelines from days to hours.
- Proposal Generation: Harvey enables Mijares to develop tailored proposals more quickly, increasing the firm’s ability to respond to opportunities under tight timelines and win business by showcasing speed and sophistication.
- Litigation Strategy: Partners use Harvey to identify inconsistencies in expert reports, a task that once required hours of manual review, now takes minutes, improving both response time and quality
Impact
The firm has elevated its ability to deliver better results, faster, all while maintaining the quality and legal rigor that define its brand.
“We’re not just working faster,” said Fuentes. “We’re outperforming the competition by combining our deep legal expertise with powerful AI.”
Looking ahead, Mijares sees Harvey as more than a platform, it’s a strategic partner.
“Harvey is quickly becoming a true business partner, growing alongside us and adapting to our needs to continue improving the efficiency, quality, and speed of legal services,” de Uriarte said.
As client expectations rise and competition intensifies, Mijares uses Harvey to stay ahead, strengthening relationships and delivering high-impact results.
