No, common law marriage lacks formal recognition in Argentina, despite its social prevalence. Only civil or religious marriages registered under the Civil Code (Law 26.618) confer legal rights, leaving cohabiting couples without automatic protections unless they draft private agreements.
Key Regulations for Common Law Marriage in Argentina
- Civil Code Exclusivity: Law 26.618 (2010) mandates registration via civil registry (Registro Civil) for marital rights; cohabitation alone does not suffice.
- Limited Inheritance Rights: Unregistered partners cannot inherit intestate under Article 2482 of the Civil Code, though courts may recognize de facto unions (uniones convivenciales) under Law 26.994 (2015) with judicial validation.
- 2026 Compliance Shifts: The Ministerio de Justicia is piloting a digital cohabitation registry in Buenos Aires, but participation remains voluntary and non-binding for legal protections.
Couples seeking rights must formalize unions through civil marriage or, in select cases, petition courts to recognize uniones convivenciales under stringent evidentiary standards (e.g., shared domicile for ≥2 years, documented cohabitation). Provincial variations exist, but Buenos Aires and Córdoba enforce stricter documentation requirements. Legal counsel is advised to navigate these constraints.
