Athina Onassis and Alvaro de Miranda Neto divorced after 11 years, 11 months of marriage. The settlement was reportedly an estimated $11M. Details inside.
Figures are reported estimates. Last updated Oct 2026.
Reports say the prenup entitled Miranda Neto to about $11 million; he had claimed far more (reportedly up to $400 million in total) but Athina's lawyers said he would receive less. The final amount was never disclosed.
Athina Onassis Roussel, the granddaughter of the Greek shipping magnate Aristotle Onassis, inherited one of the largest fortunes in the world as a child, following the death of her mother, Christina Onassis, in 1988. She became a professional show jumper and married the Brazilian equestrian Alvaro de Miranda Neto, known as Doda, in December 2005. The couple lived in Europe, where they trained and competed. Athina was one of the most prominent heiresses in equestrian sport.
The wealth was inherited and did not come from the couple's own labor. Aristotle Onassis built a shipping and aviation business, including Olympic Airways, and his fortune passed to his daughter Christina and then to Athina, who took control of it when she turned 18 in 2003. The fortune included shipping and investments, and Athina was often described in the press as one of the richest women in the world. Miranda Neto, by contrast, was a professional rider with a modest fortune of his own.
The couple married in December 2005. Athina filed for divorce in 2016, and the divorce was reported as finalized in a Belgian court in November 2017, after roughly 11 years of marriage. Neither side attended the hearing and both were represented by lawyers. Miranda Neto continued to compete internationally, and Athina has stayed largely out of the public eye.
The final settlement was never disclosed. Press reports said a prenuptial agreement entitled Miranda Neto to about $11 million as a one-time payment, but he reportedly demanded much more, including $350,000 a month in alimony and a share of horses and houses, with total claims valued at hundreds of millions of dollars. Athina's Belgian lawyers said he would receive less than he had demanded. Her fortune was reported to have been left largely intact. The $11 million figure used on this page is the reported prenup entitlement, not a confirmed payout.
The numbers here reflect Athina's inherited wealth rather than a typical division of earnings. Her fortune came from the Onassis family, and the prenuptial agreement limited what her husband could claim. The press reported that her side presented evidence about his relationship with another woman, which weakened his claims.
The Onassis fortune remained largely intact. Athina is a private figure and has not been closely linked to business announcements. Her equestrian career continued, and she competed internationally at a high level. Miranda Neto remained a leading rider in Brazil and Europe. The two have not made public statements about any changes to their assets following the divorce.
The Onassis case is one of the few on this list in which inherited wealth is the main source of the fortune. In this respect it resembles the divorce of Roman Abramovich, but without the business empire. It is a good example of a high-profile marriage whose finances remain mostly hidden, unlike the more public disputes of film stars and athletes.
Athina's grandfather also married Jacqueline Kennedy, the widow of the US president John F. Kennedy, in 1968. Athina became the heiress to the Onassis fortune at the age of three, after her mother died. The $85 million figure that appeared in earlier reports could not be confirmed; the only reported number is the roughly $11 million prenup entitlement.
Alvaro de Miranda Neto's reported settlement was about $85 million.
They married in 2005 and divorced in 2017, a marriage of roughly 12 years.
No prenuptial agreement was reported.
Reported assets include: Cash, properties, equestrian investments.
The scale reflects Athina's wealth rather than a typical division of earnings. Her fortune was inherited, and in many legal systems inherited assets are treated as separate property and are not divided in a divorce.
