Built on Experience, Driven by Purpose
Built on a foundation of seasoned leadership and nationwide collaboration, Atanante & Ilagan stands as a dynamic full-service firm committed to excellence in legal practice.
Atanante & Ilagan Law is a full-service law firm based in Quezon City. The firm was established by partners who previously served as name partners in the multi-awarded law office Gargantiel Ilagan & Atanante Law, bringing with them extensive experience, professional leadership, and a strong foundation in legal practice.
Though a new firm, Atanante & Ilagan Law is supported by established legal networks across major cities and key jurisdictions in the Philippines, including Baguio City, Angeles City, Parañaque City, Muntinlupa City, Naga City, Puerto Princesa City, Cebu City, Bohol, Iloilo City, Malaybalay City, Cagayan de Oro City, Tagum City, and General Santos City.
This network is rooted in the partners’ active participation and leadership in the Integrated Bar of the Philippines, as well as their connection with the Philippine Legal Network (PHILNET), a network of competent and principled lawyers in private practice across the country.
The firm provides comprehensive legal services to corporate clients, with strengths in employment law, litigation, and dispute resolution. Its lawyers have extensive experience handling cases before courts, administrative agencies, and regulatory bodies nationwide.
These capabilities allow Atanante & Ilagan Law to efficiently manage multi-jurisdictional litigation and provide consistent, strategic legal counsel across various venues.






Atanante & Ilagan (AI Law) was founded on a simple principle: the practice of law must evolve alongside the world it serves.
