Guedes Medeiros Vasconcellos & Mello

What Guedes Medeiros Vasconcellos & Mello does

Guedes Medeiros, Vasconcellos & Mello is a private Brazilian boutique law firm founded in 1999 and headquartered in the Santo Amaro district of São Paulo. The firm specializes in "Wealth Management Jurídico" — an integrated practice spanning succession planning, family holdings structuring, prenuptial agreements, divorce, probate, corporate compliance, labor law, and real estate due diligence. It is led by three partners: founder Marcelo Guedes Medeiros (also Relator of the OAB/SP Tribunal de Ética e Disciplina), Fabíola Macedo Vasconcellos (Partner for Corporate and Labor Law, Vice-Superintendente of ACSP), and Sheila Moralles Mello (Partner for Family and Succession Law, trained under Flávio Tartuce and Giselda Hironaka). The firm claims national reach across Brazil from its single São Paulo office.

The firm operates a quote-based professional services billing model with no publicly disclosed pricing. Client acquisition is driven by a mix of institutional credibility (OAB/SP and ACSP affiliations), thought leadership content via a blog and social media (Instagram, Facebook), and direct WhatsApp/email engagement. There are no disclosed third-party distribution channels, no technology platform, no app, no API, and no AI/ML tooling — service delivery is partner-led and labor-intensive. The practice serves high-net-worth individuals, family businesses, and corporate clients requiring complex multi-generational wealth structuring, with engagements reportedly involving multi-7-digit transaction values.

The firm is independently owned by its three named partners, with no parent company, external investors, subsidiaries, funding rounds, or public listing. Headcount is 14 total, comprising the three partners and supporting legal professionals. Operating geographies are limited to a single Brazilian office, though the firm markets itself as serving clients across national territory. No M&A activity, restructurings, regulatory actions, or material corporate structural moves are disclosed in the source material.
