Son Who Takes Care of Elderly Parents Alone Can Demand Cost Sharing in Court and Force Negligent Siblings to Pay Proportional Child Support, Confirm Courts.
Caring for elderly parents is one of the most sensitive topics in Family Law and, at the same time, one that generates the most conflicts within Brazilian families. In many households, only one child takes on the financial and emotional responsibility of maintaining the dignity of the parents, bearing costs for health, food, and housing.
But the Civil Code, in its article 1,696, is clear: the duty to provide for support is mutual between parents and children and extends to all ascendants and descendants. This means that no child can remain inactive. The law allows those who bear the burden alone to go to court and demand that siblings contribute proportionally to their economic capacity.
What the Law Says About Alimentary Obligation Between Relatives
The article 1,694 of the Civil Code establishes that relatives can ask each other for the support they need to live in a manner consistent with their social condition.

Article 1,696 adds: “the right to alimony is mutual between parents and children and extends to all ascendants.”
In practice, this means that children have a legal obligation to support elderly parents when they can no longer support themselves.
The obligation is divided proportionally: those with more resources should contribute more, and those with less contribute within their means.
Jurisprudence Confirms Proportional Sharing Among Siblings
This understanding has been consolidated in various courts. In 2023, the São Paulo Court of Justice (TJ-SP) decided that a child who was bearing the medical and caregiver expenses for an elderly mother alone had the right to demand proportional contributions from the siblings.
The Superior Court of Justice (STJ) has also recognized that the overloaded child can file a regressive action against negligent siblings. The basis is the principle of family solidarity, which prohibits unfair concentration of responsibilities on only one child.
How Judicial Collection Against Negligent Siblings Works
The child who takes care of the parents alone can file a support action in the name of the elderly father or mother, naming all the siblings as co-responsible. The judge will assess the needs of the elderly and the financial capacity of each child, defining the proportional contribution.
Additionally, there is the possibility of a regressive action, whereby the child who has already covered expenses can seek reimbursement for the portion that belonged to the siblings. This action is permitted when there is proof that the payment was made exclusively by one of the children and that there was a real need for the elderly person.
Practical Examples of Judicial Decisions
In a decision from 2022, the TJ-MG ordered two siblings to contribute to part of the medical and caregiver expenses for their elderly mother after the third child proved that they had been covering all costs alone. The court emphasized that “caring for parents is not a choice, it is a legal duty.”
Another case judged by the TJ-RS recognized the right of a child who had already spent more than R$ 30,000 on medications and consultations to demand half of the amounts from the siblings, since they had the financial means but chose not to participate.
Experts Emphasize the Principle of Family Solidarity
According to civil law professor Maria Berenice Dias, “the care of elderly parents must be shared among all the children. The omission of any one of them constitutes a breach of legal and moral duty, which can be corrected by the Courts.”
Family lawyer Rolf Madaleno adds: “there is no room to transfer the entire burden to one child. Family solidarity is one of the pillars of Brazilian Law, and jurisprudence has reinforced this principle.”
Social and Emotional Impact of Mandatory Sharing
The ability to take legal action against negligent siblings not only alleviates the financial burden on the caregiver but also serves as an educational tool: it reinforces that responsibility for elderly parents is shared.
In practice, decisions like these also reduce future estate disputes, as judicial records clearly indicate who contributed and who did not contribute to the sustenance of the parents.
Courts Reinforce That No Child Can Remain Inactive
The message from the courts is clear: caring for elderly parents is not a favor; it is a legal duty. The child who sacrifices alone can demand that the siblings participate, whether by sharing current expenses or reimbursing past costs.
The Courts have recognized that allowing some to remain inactive while burdening others would violate the principle of family solidarity, as provided in the Civil Code and established in jurisprudence. Thus, each child is accountable according to their capacity, ensuring that the rights of the elderly are preserved and that the burden is shared fairly.

Olha que está acompanhantes não foi amarrada pra lá não, eu mesmo já tive duas cuidadoras de minha mãe, eu tinha consciência, mas era minha sobrevivência, na época era como eu podia, já pensou se fosse pra mim pagar um valor de causas astronomica a uma destas minhas colaboradoras aí meu nem sei o que seria de mim.
No caso aí se consolidar este valor da causa seria justiça da legalidade fazendo injustiça com a legitimidade.
É se depender do Estado e os TRTs, famílias de baixa renda vão ter que enviar seus idosos para asilos, dizem que farão casas dias, será? A gente vê cada valor de causas astronômica tipo que sei de um caso que a acompanhante usou métodos cruel para cobrar a família sendo que a idosa estava viva e em estado grave, ainda está acompanhante usou o endereço desta idosa sem o consentimento dela para receber o bolsa família, nem os filhos sabiam de tal fato. Será que neste caso o martelo da legalidade não está ferindo a legitimidade. Porque está acompanhante não foi pra lá amarrada não. Eu mesmo tive que cuidar de minha mãe e tive duas colaboradoras era o que minha família podia pagar e nem na vila vicentina tinha vaga e em asilos particulares a gente não tinham condições de pagar devido ao preço. Aí graças a Deus e estas duas pessoas colaboradoras que combinei com elas pude olhar em paz, a Justiça mesmo para fazer a curatela de minha mãe só entregou 15 dias antes de seu falecimento. Assim penso que demandas de família em relação a valores de causas deveria ter certos limites diferentes de empresas, família presa o cuidado e empresa o lucro. Tem base uma causa de 3 anos e 3 meses tomar um bem de família que um pai trabalhou anos a par para adquirir. Isto é Brasil
