ZS Advogados Associados

ZS Advogados Associados is a boutique law firm founded by Zachariah Zagol — the first American citizen to pass the Brazilian Bar Exam (OAB) — and Karina Peres Silvério. Based in Presidente Prudente, São Paulo, the firm serves clients throughout Brazil and internationally.

We specialize in serving foreigners, expats, investors, digital nomads, and international companies who need legal representation in Brazil. Our practice areas include immigration law, real estate transactions and due diligence, corporate structuring and business formation, civil litigation, and family law.

What sets us apart is that our founding partner didn't just study Brazilian law — he lived it. Having moved to Brazil at 18 and built his life, family, and businesses here, Zac brings a perspective that few attorneys can offer: genuine understanding of what it means to navigate Brazil as a foreigner.

We respond within 24 hours, work across all time zones, and operate fully in English and Portuguese.
