Case shows how digital receipts can change a lottery dispute: bettor lost the pool ticket, gathered payment records, conversations with the lottery, and a police report, and obtained a favorable decision against Caixa to receive the prize.
A woman from São Paulo almost saw a Mega da Virada prize slip away due to a detail that terrifies any bettor: the winning ticket simply disappeared. The case seemed lost, as Caixa required the physical receipt to release the money.
But the story turned in court. According to the official release from the Federal Court in São Paulo, the 7th Chamber-Special Federal Court of São Paulo/SP ordered the Caixa Econômica Federal to pay about R$ 14,000 to a participant of a winning pool in the quina of the Mega-Sena da Virada 2024.
What saved the bettor was not the paper, but a set of digital evidence: Pix, WhatsApp conversations, notarial act, police report, and information from the lottery itself. The decision turned an apparently simple case into a warning for millions of Brazilians who buy pools and keep receipts on their phones.

Woman bought Mega da Virada pool by Pix and lost the ticket before withdrawing the prize
The participant had bought shares of pools at a lottery in São Paulo, including a bet on the Mega da Virada 2024. The payment was made by Pix, totaling R$ 332.65, which later became one of the main pieces of evidence in the process.
Among the games purchased was a pool share that hit the quina in the New Year’s draw. Since the prize needed to be withdrawn at Caixa, the woman was informed by a lottery employee that she should go to a bank branch to collect the amount.
It was at this moment that the shock came: when looking for the receipt, she realized she had lost the physical ticket of the winning bet. Without the receipt in hand, Caixa denied the payment.
Caixa denied the payment because the bettor no longer had the physical ticket
Caixa argued that its rules require the presentation of the original ticket to validate the bet and release any prize. In practice, without the paper, the institution understood there was no way to confirm the ownership of the share.
For many bettors, this would be the end of the story. After all, lotteries usually treat the ticket as an essential document to prove the right to the prize. But the woman decided to take the case to Federal Court.
She filed a police report for the loss of the ticket and gathered documents to try to demonstrate that she had indeed participated in the winning pool. The strategy worked.
Pix, WhatsApp, and notarial record became the evidence that changed the case
The turning point came because the bettor managed to present a set of evidence considered sufficient by the judge. Among the documents were the Pix receipt, conversations with the lottery via WhatsApp, and a notarial record documenting these messages.
In the conversations, according to the decision, there was information about the request for bets, the confirmation of the games, and the communication that one of the shares had been awarded. In other words: even without the paper ticket, there were digital traces indicating that the woman bought the bet and was part of the pool.
This detail is the strongest point of the story. The case shows how digital evidence can have decisive weight when there is a conflict between an administrative rule and the attempt to prove a right in court.
Court understood that the absence of paper could not erase the right to the prize
Federal judge Fabiano Lopes Carraro recognized that the lottery ticket is important as proof, but evaluated that the loss of the document could not, by itself, eliminate the bettor’s right when there were other consistent proofs.
The decision considered that the woman demonstrated her participation in the winning pool and that Caixa was unable to sufficiently dismiss the set of evidence presented. As a result, the institution was ordered to pay the amount corresponding to the bettor’s share.
The amount was set at R$ 14,265, with monetary correction from the date of the draw and interest from the citation. The decision is of first instance.
Case raises alert for those who buy pools of Mega-Sena, Lotofácil, or Quina
The story serves as a warning for anyone participating in lottery pools, especially when the purchase is made via Pix, WhatsApp, or through lottery intermediaries. The ideal is still to keep the original ticket in a safe place, take legible photos, and keep payment receipts.
But the case also shows that, in a legal dispute, digital documents can help reconstruct the operation. Pix receipt, messages, notarial records, and police reports can form an important line of evidence.
For those who bet, the lesson is straightforward: do not rely solely on memory or casual conversations. Keep everything. The ticket is still the main document, but, as this woman discovered, the cellphone can also make the difference between losing everything and being able to claim the prize.
