Whose Idea Was It? New Civil Code, Updating the 2002 Version, Proposes to Exclude Negligent Children and Ex-Spouses from Inheritance: PL 4/2025 Revolutionizes the Rules of Succession in Brazil
Brazil is about to experience the biggest transformation in Civil Law since 2002. The new Civil Code, currently under discussion in the National Congress as PL 4/2025, revises more than 20 years of legislation and redefines fundamental concepts regarding family, marriage, inheritance, and succession. The proposal, drafted by a committee of jurists coordinated by Minister Luis Felipe Salomão of the Superior Court of Justice (STJ), has already been submitted to the Senate and is expected to be voted on in 2025.
The new text aims to adapt the Civil Code to the social and family changes of recent decades, recognizing realities that were previously excluded from the law, such as children of single mothers, socio-affective relationships, families formed by stepparents, and same-sex couples, as well as new family configurations that have become common in the country.
However, what stands out the most are the changes in inheritance rules and the new treatment of family and succession relations, which may change the legal future for millions of Brazilians.

Asset Division: Know What Cannot Be Divided in Case of Divorce
Negligent Children and Ex-Spouses May Be Excluded from Inheritance
One of the most controversial points of the project is the creation of legal grounds for exclusion of heirs, which is currently extremely limited.
According to the text, children who emotionally or materially abandon their parents may lose their right to inheritance if the negligence is proven.
The measure also applies to ex-spouses, who will no longer have any stake in the property after the divorce, even if they have been together for many years, unless there is a court decision determining compensatory alimony or previously defined division.
Experts point out that this change seeks to reinforce emotional and financial responsibility between parents and children, reducing legal disputes and situations where heirs benefit from those they have neglected during their lives.
Children of Single Mothers and Socio-Affective Bonds Gain Full Protection
The new Civil Code also marks a historical advance by equating socio-affective and biological children.
This means that a person raised by stepmothers, stepfathers, or a partner of one of the parents may be recognized as a legitimate heir, even without a biological link.
In practice, children of single mothers or of informal unions will have the same succession rights as children recognized on paper.
This point reflects recent decisions from the STF and STJ, which have already accepted multiparentality and affective filiation as legitimate grounds for guaranteeing inheritance, alimony, and inclusion in civil registration.
Multiparental Families and New Forms of Union Gain Legal Backing
Another significant novelty is the legal recognition of multiparental families, where a person can have two, three, or more recognized parents in the civil registry — for example, a biological father and a stepfather, or a biological mother and a stepmother.
All will have equal responsibility and rights in relation to the children, including custody, support, and succession.
The text also consolidates the right to digital inheritance, allowing for virtual assets such as social media accounts, crypto-assets, and content platforms to be transferred to heirs. This inclusion represents an adaptation of Civil Law to the technological era and is already considered one of the project’s greatest innovations.
Marriage, Stable Union, and Division Will Have New Rules
In the marital sphere, the new Civil Code proposes to flexibilize the property regime and expand the couple’s autonomy.
Currently, individuals over 70 years old are required to adopt total separation of assets, but the reform proposes that this rule be revoked, allowing elderly couples to freely choose their desired regime.
In addition, the text recognizes new forms of union, including same-sex marriages and plural stable unions, although the latter point still generates intense debate in the Congress.
The goal is to adapt the law to family diversity and reduce legal loopholes that currently fuel legal disputes following separations or deaths.
Social and Legal Impact of the Reform
For legal experts, this update is a milestone comparable to the 1988 Constitution in terms of social impact. It attempts to balance traditional values and new demands of modern society, without ignoring the evolution of customs and technologies.
By broadening the notion of family, including affective ties, and excluding negligent heirs, the project is expected to profoundly transform the dynamics of family and succession relations in Brazil, in addition to modernizing the legal treatment of issues such as digital inheritance, assisted reproduction, and multiparentality.
The new Civil Code of 2025 still needs to be debated and voted on by the Senate before moving to the Chamber of Deputies, but it is already seen as one of the most comprehensive legal reforms of the century.
If approved, it will bring new rights and duties for millions of Brazilians, from the recognition of children raised outside biological ties to the redistribution of inheritance according to real ties of affection and coexistence.
One thing is certain: Brazilian families will never again be viewed the same way by the law.
