The enviable track record of Barros & Errázuriz's 11-member team includes class actions and mediation procedures involving the Chilean Consumer Law Authority (SERNAC). The practice covers a broad range of industries, including public services and utilities (water distribution and mail), telecoms (mobile services and satellite TV), education, real estate and healthcare. The practice is jointly led by civil and commercial litigation and arbitration specialist, Javier San Martín, who routinely assists with consumer matters and class actions; competition and antitrust expert Luis Eduardo Toro; David Cademartori, who focuses on administrative and public law, but is also experienced in competition and antitrust matters (particularly within the telecoms and energy sectors); and José Luis Corvalán, whose specialisms include consumer law. Among the firm's senior associates, litigation and arbitration-focused Isidora Fernández is highlighted. Cristián Pérez left the firm for real estate holding Pasmar in January 2022.

The advertising and consumer law practice at full-service legal giant Carey is particularly active in voluntary collective procedures before SERNAC; advertising, marketing and recall campaigns; safety and warranty policies; and importing and commercialising products in the Chilean market. Another area of strength is e-commerce, while the group also has broad litigation experience in class and individual actions surrounding product liability, misleading advertisements, consumer safety and contractual compliance. The practice co-heads are Guillermo Carey  and Aldo Molinari  , whose recent activities include co-leading the defence of General Motors Financial Chile against a SERNAC-filed class action for allegedly infringing consumers’ rights in relation to extrajudicial collection practices. At associate level, Mónica Pérez's broad litigation and commercial arbitration practice includes consumer protection mandates, and Kureusa Hara  is an up-and-coming lawyer who focuses on advertising legislation and consumer regulation. Former senior associates María José Martabit and Eduardo Reveco both exited the firm in late 2021 (for an academic role at the University of Washington and PAGBAM Schwencke Chile, respectively).

The consumer and advertising law practice at FerradaNehme consistently assists mass-market companies with litigating individual consumer disputes, as well as class actions. The 'competent team of highly specialised professionals' is also sought out for its representation of clients before SERNAC, and has notable experience in voluntary collective procedures. Additional expertise includes the design and improvement of prevention and consumer-related compliance models. Heading up the department, Stella Muñoz is an expert in consumer protection law, privacy and personal data protection, as well as related proceedings - particularly complex class actions. Muñoz’s track record also includes handling regulatory issues for multinational company VTR Comunicaciones, in relation to television, internet, and fixed and mobile telephony matters. Dispute resolution specialist Nicolás Ubilla is also active in the group; while among the associates: senior Nicolás Morales focuses on intellectual and industrial property, litigation and consumer law; Aníbal Korn is an active litigator; and Arturo Arriagada's practice takes in consumer law, financial regulation and data protection.

Leading the technology, privacy and media group, Rodrigo Lavados is an IP specialist, whose practice also covers consumer protection; competition law practice head Juan Cristóbal Gumucio provides additional partner-level support; and senior associate Gabriel Pensa's broad practice expertise includes advertising, consumer protection and food labelling.

At associate level, senior Dafne Guerra  ‘s practice includes both litigation and consumer law-related corporate advice; the practices of fellow senior Juan Pablo Zamora , and associate Gonzalo Bravo , also take in consumer law.
