Man Transfers R$ 4 Thousand Via Pix By Mistake, Is Blocked By Receiver And Turns To Justice, Which Orders Return And Recognizes Bad Faith For Unjust Enrichment. Check Below The Details Of The Occurred
The case took place in Águas Claras (Federal District) and was reported by the legal portal Migalhas on February 4, 2025. A resident of the city, while trying to make a bank transfer, incorrectly typed the Pix key and sent R$ 4 thousand to an unknown person. The seemingly simple mistake triggered a legal battle that ended with a favorable decision for the return of the amount and a warning to millions of Brazilians about the risks of instant transfers.
According to the report, after realizing the mistake, the author tried to contact the recipient to resolve the situation amicably. However, he was blocked on social media and messaging apps, and the woman began to ignore all communication attempts. The behavior considered to be in bad faith led the case to the 2nd Special Civil Court of Águas Claras, which ordered the full return of the money.
Justice Recognizes Good Faith Of The Sender And Condemns Receiver To Return The Pix
The ruling issued by the responsible judge acknowledged that the author acted in good faith when trying to recover the amount and that the woman’s attitude constituted unjust enrichment, according to Article 884 of the Brazilian Civil Code.

According to the magistrate, “whoever receives undue value and tries to evade return with subterfuge commits an unlawful act.” The decision ordered that the amount be returned in full, emphasizing that the mistake does not exempt the obligation of restitution.
In addition to the return, the judge emphasized that the defendant’s behavior of blocking the sender and altering her profiles on social media demonstrated a clear intention to appropriate a value that did not belong to her.
This conduct, according to legal understanding, violates the principles of honesty, good faith, and transparency that govern civil and commercial relations.
Bank Was Exempt From Responsibility For The Mistaken Transaction
One of the central points of the trial involved the responsibility of the financial institution. The author alleged that the bank could have helped reverse the error, but the Justice understood that there was no failure in the banking service.
The ruling highlighted that Pix is an instantaneous and irreversible system, which means that, once the transaction is completed, it is not possible for the bank to make a unilateral reversal, unless the recipient authorizes or there is a court order.
According to the decision, “the financial institution processed the transfer according to the data provided by the user. The error originated exclusively from the client, and not from the banking system.”
This understanding has already been consolidated in courts across the country, reinforcing that the bank is not liable for errors in typing Pix keys.
Blocking And Alteration Of Profiles Reinforced The Understanding Of Bad Faith
As reported by Migalhas, the woman who received the amount blocked the sender and altered her profiles on social media, making it difficult to locate and rendering any attempt at an agreement impossible. This attitude was considered clear evidence of bad faith and decisive for the conviction.
The judge highlighted that the mere receipt of the undue amount already generates the obligation of return, but the evasive behavior increases the severity of the civil infringement.
The decision further emphasized that withholding money received by mistake is conduct that can, in extreme cases, constitute the crime of embezzlement, provided for in artigo 168 of the Penal Code. Although the proceeding in question was limited to the civil sphere, the defendant’s posture could lead to criminal measures if there were proof of continued intent.
The Rise Of Pix And The Increase In Mistaken Transfers
Since its creation in 2020, Pix has become the main means of payment in Brazil, with over 180 million active users, according to data from the Central Bank.
On average, more than 180 million transactions are carried out per day, and with the popularization of the system, cases of mistaken transfers due to typing errors, outdated QR Codes, or similar contacts have also increased.
These incidents are increasingly being taken to court. In 2024, the National Justice Council (CNJ) recorded a 47% increase in cases involving undue transfers via Pix, most of which were related to non-returned amounts.
The case in Águas Claras reinforces the need for double attention when checking the recipient’s data before confirming a transaction. Unlike traditional transfers (TED/DOC), Pix is instantaneous, and the money arrives in the recipient’s account in less than 10 seconds — making reversal practically impossible without consent.
What To Do If You Transfer Pix By Mistake
Banking law experts explain that, upon realizing the mistake, the user should act immediately.
The recommended steps are:
- Attempt direct contact with the receiver, asking for voluntary return.
- File a police report if there is no response.
- Contact the bank, informing them of the incident so that they can register the fact internally.
- If the amount is not returned, take legal action requesting restitution based on objective good faith and unjust enrichment.
According to lawyer Fabrício Vasconcelos, a specialist in digital and financial law, “whoever receives Pix by mistake and refuses to return the money commits a civil unlawful act, and depending on the case, may face criminal charges.”
The specialist emphasizes that, although the bank cannot reverse the amount on its own, it should cooperate with Justice and provide information for locating the receiver.
A Warning For Millions Of Users
The incident in Águas Claras (DF) is yet another example of how a simple typing error can cause major disruptions. The victim had to turn to the judiciary to recover a considerable amount, facing the emotional and bureaucratic wear of the process.
Cases like this show that Pix, despite its practicality, requires extreme caution, especially in high-value transfers.
The judge in the case highlighted in his ruling that “trust is essential in the financial system, but cannot justify negligence. The responsibility for verifying the data before confirmation rests entirely with the user.”
The case concluded with the determination for immediate restitution of R$ 4 thousand, and the decision is already being cited in other similar judgments in the Federal District.
