Donald Trump Jr. and Ivanka Trump are due to testify next month before the New York attorney General's civil investigation into their family's business practices.
According to court orders and stipulations, the three witnesses will begin testifying on July 15. Each member of the family will be testifying separately, and the parties have until the week's end to complete their depositions.
According to court documents, their testimony will not take place on the July date if the Court of Appeals, the highest court in the state, stops the judge from ordering that the Trumps testify.
A panel of state Appellate Division judges denied Trump's request to evade a deposition during the investigation by Attorney General Letitia Jam's office.
The Trump lawyers argued that the subpoenas should not be issued because James' investigation was politically motivated and intended to increase an ongoing criminal investigation into the company by Manhattan's district attorney's.
NBC News reached out for comment to the lawyers representing the family.
