No, Brazil does not recognize common law marriage as a legal marital status under federal law. The 2002 Civil Code (Law No. 10.406) and subsequent rulings by the Superior Court of Justice (STJ) explicitly require formal marriage registration for full legal protections. Informal unions may trigger limited rights under labor or inheritance laws but lack marital equivalence.
Key Regulations for Common Law Marriage in Brazil
- Formal Registration Mandate: The Civil Code (Art. 1.515) and STJ jurisprudence (e.g., REsp 1.299.866) confirm that only civil or religious marriages registered with the Cartório de Registro Civil confer marital status. Informal cohabitation does not suffice for spousal rights.
- Limited Rights via União Estável: Cohabiting partners may claim união estável rights (Art. 1.723, Civil Code), but this requires proof of a stable, public relationship akin to marriage. The Conselho Nacional de Justiça (CNJ) enforces strict documentation standards for such claims.
- 2026 Compliance Shift: Proposed amendments to the Civil Code (PLS 280/2021) aim to codify união estável further, but no changes recognize common law marriage. The Receita Federal and INSS continue to deny spousal benefits to unregistered partners.
