A firm specialized in providing solutions for medium and high complexity cases.

Uniqueness and security in solving criminal problems.

The office

From Classical Criminal Law to Economic Criminal Law, Assunção Lopes Advocacia is a law firm specializing in Criminal Law, practicing with ethical/theoretical rigor and in a handcrafted manner, founded on a philosophy and methodology of work that contrasts with mass litigation.

The term "handmade" refers to the work of an artisan: careful, meticulous, personalized, and focused on the unique quality of each piece, rather than on large-scale production.

In a legal context, meticulousness means treating each case as unique, dedicating time, careful attention, and a defense strategy completely customized to the specific circumstances of the client and the case.

The artisanal character, typical of the essence of criminal law practice, combined with the dynamism necessary to work on high-profile and highly complex cases, are the pillars that support the day-to-day operations of the firm.

The lawyer's high level of technical expertise and solid, ongoing academic training are the result of the firm's relentless pursuit of unwavering defense of its clients' fundamental rights and guarantees with excellence.

The firm takes the maxim of Heráclito Fontoura Sobral Pinto, considered the lawyer of the century, literally: "criminal law is not a profession for cowards."
