Court Reaffirms That Bonds of Affection Have Legal Force and Ensure Equal Distribution of Assets with Biological Children

A decision from the São Paulo Court of Justice (TJ-SP), released in November 2024, consolidated a landmark in Brazilian Family Law. The 3rd Chamber of Private Law upheld the ruling from the 3rd Family and Succession Court of Sorocaba, which recognized the affectionate filiation of a woman with her adoptive father. The decision granted her the same inheritance rights as the biological daughter.

The case is based on Article 1.593 of the Civil Code, which defines that “kinship is natural or civil, depending on whether it arises from consanguinity or another origin.” This phrase — “another origin” — has been interpreted by the courts as a legal opening for the recognition of affectionate ties. This understanding is in accordance with the 1988 Federal Constitution, which values human dignity and the protection of family.

Recognition of Affective Bonds in Justice

The plaintiff was raised since birth, in 1993, by a man who took her in after her mother died during childbirth. The custody occurred with the consent of the biological father. Over the years, the man continuously and publicly played the role of a father.

After his passing in 2021, the woman’s right to filiation was contested by her biological sister. She attempted to prevent the distribution of inherited assets. However, the court concluded that the affectionate bond was well established.

Among the evidence were the wedding invitation in which the deceased appeared as the father and official documents indicating the plaintiff as a dependent. There were also witness testimonies demonstrating long-lasting family coexistence.

According to the reporting judge, desembargador João Pazine Neto, the evidence “demonstrates the existence of a legitimate parent-child relationship.” He also emphasized that “paternity can arise from biological, legal, or affectionate ties.”

Legal Foundations and Social Evolution

The judge’s understanding reflects a significant change in the concept of family. The Civil Code, by admitting kinship by “another origin,” legally recognizes affection as a legitimate basis for family relationships.

Thus, the TJ-SP reaffirmed that love, coexistence, and care produce concrete legal effects, including in the succession and property fields. This interpretation, according to experts like Maria Berenice Dias, aligns with the principle of human dignity and the best interests of the child. Both are constitutional pillars of modern Family Law.

Additionally, decisions like this strengthen the idea that affectionate filiation does not depend on genetic ties. It is based on continuous presence, social recognition, and affective responsibility. Thus, the law accompanies social transformations and broadens legal protection to various family forms.

Legal and Symbolic Impacts of the Decision

The decision of the São Paulo Court of Justice also holds a significant symbolic weight. It reaffirms that affectionate and biological children have equal rights in the distribution of assets. This understanding prevents discrimination and ensures equity in family relations.

The Sorocaba case reinforces an important precedent for other courts across the country, which have followed the same interpretative line. Following this decision, new socioaffective recognition actions are likely to be analyzed under the same lens. This consolidates a more humane jurisprudence that is coherent with Brazilian social reality.

Experts assert that this advancement demonstrates the maturity of the legal system. It recognizes love and coexistence as elements that build family identity. Justice, therefore, begins to operate more closely to people’s real lives. After all, emotional ties hold as much value as biological ones.

A Milestone of Equity and Human Recognition

The decision of the 3rd Chamber of Private Law, rendered in November 2024, represents a turning point in Brazilian jurisprudence. It reaffirms the role of affection as a legitimate source of family rights and duties.

For the TJ-SP, denying legal effects to an affectionate relationship would be to deny the very essence of human coexistence. The court made it clear that affection, when built publicly, continuously, and voluntarily, can generate full family ties.

The Sorocaba case not only ensured succession equality between biological and affectionate daughters. It also reinforced the notion of justice based on emotional truth.

By recognizing the legal value of affection, the Brazilian Justice moves towards a more sensitive and adaptable law to social transformations.

After all, wouldn’t love, when recognized by law, be the most legitimate inheritance a father can leave?
