While no longer an executive for the Trump Organization, former President Donald Trump's eldest daughter must appear in court, along with two of her brothers, before the case wraps up next month.

Ivanka Trump challenged the demand that she appear in court, but Judge Arthur Engoron ruled in favor of New York Attorney General Letitia James' office on Friday, NBC News reported.

Prosecutors argued her testimony was necessary despite the fact she is not a defendant in the case.

Ivanka Trump can appeal the ruling, but as it stands, she is likely to be called to testify in a Manhattan courtroom on Nov. 3, prosecutor Kevin Wallace said.

Her brothers Donald Trump Jr. and Eric Trump will testify before her, on Wednesday and Thursday, respectively, Wallace said.

Donald Trump is expected to testify on Nov. 6, and the case will wrap up shortly after.

An appeals court ruled earlier this year that Ivanka Trump could not be subpoenaed to testify in the civil case. Attorneys for Trump cited that ruling in a statement challenging Engoron's ruling.

The legal team accused James' office of an attempt "to continue to harass and burden President Trump's daughter long after" another court had "mandated she be dismissed from the case."

James' office said that while Ivanka Trump is no longer affiliated with her family's business, she has intricate knowledge of it.
