Christina's attorneys said it was "a goodwill gesture," which is supposed to persuade the judge not to open court proceedings against her.
The duchess and her husband, Duke of Palma Inaki Urdangarin, were suspected of embezzling public funds from the sports charity foundation Noos Institute through the Aizoon company owned by Cristina and Urdangarin.
Last week, the case's prosecutor decided that Cristina herself is not connected to any of the crimes, but Urdangarin now faces up to 19 years in prison and a $4.3 million fine, should the judge decide to accept the prosecutor's request.
Forty-nine-year old Infanta Cristina, the youngest daughter of King Juan Carlos and Queen Sofia of Spain, and sister of current Spanish King Felipe VI, is currently sixth in line to the Spanish throne. Cristina, a mother of four, was once considered an untouchable member of the Spanish royal family, but the corruption case has triggered public anger and disapproval toward them.
