EFB Regimes Especiais, the liquidator of Banco Master, has asked a US court to compel businesswoman and influencer Martha Graeff to testify under oath and provide documents related to assets, money transfers and business dealings involving her former fiancé, Daniel Vorcaro, and 18 other people and companies.
A petition filed on Tuesday in the US Bankruptcy Court for the Southern District of Florida says Graeff is to testify in Miami on December 8 and submit documents by November 30. Her lawyer, Lucio Constantino, said she had not been formally notified and was unaware of the request, adding that she had always been available to authorities.
The request invokes Rule 2004, which allows a bankruptcy administrator to question people who may have information about a debtor’s assets. Graeff is not a defendant in the case and has been called as a witness. She may challenge the request or seek to have it set aside.
The document request covers the period from January 2018 to the present. It seeks records concerning property Graeff owns, previously owned or helped acquire that is linked to Vorcaro or others on the list, including assets held through nominees, trusts or shell companies. The categories include real estate, cars, artwork, jewelry and watches, as well as insurance policies, sale and consignment contracts, customer records and bank statements.
EFB is also seeking details of the accounts from which payments to Graeff or companies she controls originated, and the accounts that received them. The request names Graeff Holdings LLC and asks for information about services she provided to the Master business network.
The petition follows other information-gathering efforts in the case, including requests to banks Bradesco and Itaú and companies that did business with Vorcaro and his partners. The list of people and entities also includes cooperating witness Antonio Carlos Freixo Júnior, former Master executives and partners Maurício Quadrado and Luiz Antonio Bull, and companies linked to Vorcaro abroad, including Titan Capital Holding.
Florida records show that Graeff Holdings was formed on September 15, 2023, with Graeff listed as its manager. The filing does not identify the company’s owners; Florida law does not require that information for limited liability companies.
The summons was addressed to a penthouse in a luxury condominium in Surfside, north of Miami Beach. Miami-Dade County records show the property is owned by G5C Capital Corporation, a company incorporated in Ontario, Canada, one day before it bought the residence for $43.9 million. Public records do not identify G5C’s owners or indicate a connection to Vorcaro or Banco Master.
EFB began its US case shortly after Brazil’s Central Bank ordered Banco Master’s liquidation in November 2025. The liquidator was subsequently authorized to pursue the debtor’s assets in the United States. In a separate action, EFB is seeking to hold about $42 million from the sale of a Gulfstream G700 jet, registration PS-MGG, which it says was purchased with bank funds. The registration letters correspond to Graeff’s full name, Martha Gonçalves Graeff.
After private messages between Graeff and Vorcaro were leaked in April, she said she had been “dragged into a quagmire.” In a statement on her social media accounts, she said she had faced attacks and public exposure and denied involvement in the investigations. She also said she was neither under investigation nor accused of wrongdoing, and rejected reports that her assets had increased.
The report also said Vorcaro had suggested transferring assets into Graeff’s name while negotiating to buy another high-end home in Miami. He discussed setting up a trust to be registered in her name. Months earlier, he had completed the purchase of a house on Sabal Palm Road for more than $85 million.
Vorcaro’s lawyer was contacted by email on Tuesday afternoon but had not commented at the time of the report.
