Legal and social developments in Brazil are increasingly focusing on parental rights, registration trends, and the recognition of emotional bonds within family structures.

Data indicates that while approximately 1.67 million children were registered without a father’s name between 2016 and 2026, voluntary paternity recognition is trending toward record highs. The Brazilian judiciary is also shifting toward prioritizing affective bonds over biological ones, evidenced by the legal recognition of “socio-affective grandparenting,” which allows for inclusion in birth certificates. Concurrently, legal frameworks continue to refine inheritance and succession rules regarding the division of assets between spouses and descendants.

Legislative efforts to support family bonding are progressing through Law No. 15.371/2026, which mandates a gradual expansion of paternity leave. While employees, including domestic workers, currently receive 5 consecutive days of paid leave, the law establishes an incremental schedule: leave will increase to 10 days in 2027, 15 days in 2028, and reach a final duration of 20 days starting in 2029, subject to specific fiscal conditions.
