Angola's billionaire former first-daughter Isabel dos Santos and her husband are seeking to revoke a court order that froze their assets last year as part of a massive corruption probe, their lawyer said Tuesday.
Dos Santos and her Congolese husband Sindika Dokolo are accused of diverting billions of dollars from Angolan state companies during ex-president Jose Eduardo dos Santos' 38-year rule.
The couple's lawyer Walter Tondela told AFP he had filed a case against Angola's public prosecution for "presenting false documents".
Dos Santos said her lawyers unearthed the falsified evidence after they were given access to the court documents last month.
Dos Santos has built up a vast business empire over the past two decades, with stakes in several Angolan and Portuguese companies.
