The Firm
A firm specialized in constitutional and administrative law.
Who we are
Gómez Fierro Abogados is a Mexican law firm based in Mexico City, focused on constitutional and administrative law. We advise and represent companies, institutions and individuals in matters where the State intervenes — and where technical defense decides the outcome.
Every matter is handled with a strategy built from the specific case. We do not replicate templates or pre-packaged answers: we study the file, identify the decisive argument, and sustain it with rigor through to resolution.
Our practice combines deep knowledge of Mexican legal doctrine with accumulated experience across highly regulated sectors: tax, energy, antitrust, telecommunications, broadcasting, sports law and environmental matters.
Our network
We operate through a coordinated network of alliances across the country's major cities. When complexity demands it, we build multidisciplinary teams to guarantee technical depth and territorial reach.
