Superior Court of Justice Authorizes Inclusion of Debtor’s Wife in Lawsuit and Changes Understanding of Financial Responsibility Between Couples
A decision from the Superior Court of Justice (STJ) gained national attention by stating that debts incurred during marriage under partial community property regime involve both spouses. Thus, even if only one signs the contract, the other also assumes the obligation.
In October 2025, the 3rd Panel of the STJ accepted a special appeal and authorized the inclusion of a debtor’s wife in a judicial execution. The court concluded that, when the debt serves to support the family, both spouses are jointly liable. The decision reinforces that marriage creates emotional and property ties that require joint responsibility.
Understand the Case and the Decision
The case started in Goiás, when a man, married since 2010 under the partial community property regime, issued checks in 2021 and did not pay the amounts. After several unsuccessful attempts to locate the debtor’s assets, the creditor requested the inclusion of the wife in the case. He argued that the debt was for household purposes and benefited the couple.

The Court of Justice of Goiás (TJGO) denied the request, arguing that the responsibility did not extend to the wife. Consequently, the case reached the STJ, where the ministers changed their understanding and allowed the inclusion of the woman in the execution. Thus, the court established a new legal parameter on the subject.
Legal Grounds and STJ’s Position
During the trial, Minister Nancy Andrighi, the rapporteur of the case, explained that Articles 1.643 and 1.644 of the Civil Code determine that debts incurred for the benefit of the family bind both spouses jointly.
The minister emphasized that the law presumes mutual consent for all household expenses. Therefore, the creditor does not need to prove that the other spouse authorized the expenditure. Thus, both are liable for the obligation, which ensures greater legal security in property relations.
“The spouse who did not participate in the transaction can be included in the execution and later prove that the debt did not benefit the family,” said Minister Nancy Andrighi.
With this, the STJ reinforced that responsibility is shared and that the partial community property does not separate financial duties within the relationship.
Burden of Proof and Scope of the Decision
The STJ determined that those contesting the debt must demonstrate that the amount did not help the family. If there is insufficient evidence, the collection affects both spouses. Hence, responsibility becomes dependent on proving family benefit, and not merely on the signature of the contract.
The court also clarified that this presumption of consent is definitive. Thus, the spouse can be included in the execution, even without direct participation in the contract.
However, the minister highlighted that the decision does not automatically authorize the seizure of the wife’s assets. This analysis will be the responsibility of the trial court, which will decide based on the evidence presented.
Legal and Social Impacts of the Decision
The decision creates a relevant milestone for family law and for civil executions. From now on, creditors can include the debtor’s spouse in collection actions, as long as the debt was incurred during marriage and for family support.
This understanding reinforces that partial community property also implies community of duties. For this reason, couples need to act with transparency, better manage expenses, and plan their finances responsibly.
The lawyer and professor Carlos Henrique Santos, consulted by the Judicial News on October 18, 2025, explained that “the STJ’s decision provides security for creditors and encourages couples to maintain clarity about joint finances.”
Moreover, jurists point out that the new position reduces the risk of asset fraud and prevents attempts to hide assets to escape family debts.
What Changes for Couples Under Partial Community Property
With this new interpretation, debts incurred by one spouse during marriage affect the other, whenever they benefit the family. Thus, couples should reassess their financial habits, carefully evaluate contracts, and maintain constant dialogue about expenses.
The ruling shows that marriage is also an economic partnership, which requires care, organization, and mutual responsibility.
In the end, those who share life share the bills, and this reality brings new challenges and duties for Brazilian couples.
In light of this change, will Brazilian couples start rethinking how they manage their finances within marriage?
