Martins & Oliveira Sociedade de Advogados

What Martins & Oliveira Sociedade de Advogados does

Martins & Oliveira Sociedade de Advogados is a Brazilian partnership law firm (sociedade de advogados) founded in 2013 and headquartered in São Paulo, with a secondary office in Lisbon, Portugal. The firm specializes in private international law with a focus on immigration to and dual nationality acquisition from four European jurisdictions: Portugal, Spain, Italy, and Germany. Its practice covers end-to-end immigration casework including Portuguese nationality by descent (children, grandchildren, and great-grandchildren of Portuguese citizens), Sephardic descent, marriage-based nationality, and naturalization, alongside residence visa categories (D1-D7, Golden Visa, Startup Visa, Tech Visa), temporary visas, certificate search and rectification in Portugal and Brazil, NIF issuance, foreign-sentence homologation, apostille coordination, marriage and death transcription, and post-arrival services such as Portuguese company formation and real estate advisory through partner agencies.

The firm operates on a professional services model with quote-based, case-specific pricing and multi-year engagements; no public pricing exists and revenue per case varies by jurisdiction and complexity. Its client base is Brazilian families with European ancestry pursuing residency or dual citizenship, addressed through a primary segment defined by geography (vertical segmentation by destination country). The two founding partners, Flávio Martins Peron and Ema Cristina de Oliveira, both hold dual admissions (OAB/SP and Ordem dos Advogados de Portugal), and the firm cites a team of 37+ qualified professionals distributed between Brazil and Europe, alongside strategic relationships with immigration authorities and consulates in destination countries.

Technically, the firm runs a website-based client communication and digital document processing platform enabling fully electronic case submission and handling, which the firm positions as a usability differentiator. It operates LGPD- and GDPR-compliant data handling, maintains social media and blog presence via StartBeglobal, and reports serving more than 5,500 families with stated 100% effectiveness on Portuguese residence visa issuance. The firm has no mobile application, no public API, no AI features, and no disclosed funding events; it remains a private partnership with no parent company or external investment indicated in the source data.
