The battle over Amadea began in April 2022, when it was seized in Fiji at the request of the U.S. government, according to the court filings.

Though the U.S. alleges that the yacht is owned by Kerimov, who made his fortune in mining, attorneys for Eduard Khudainatov, an ex-Rosneft CEO who has not been sanctioned, say he owns the yacht, and have sought to take back possession of the vessel.

In court filings, Khudainatov's attorneys have objected to the U.S. government's efforts to sell the yacht, saying a rushed sale could lead to a distressed sale price and that the maintenance costs are minor relative to the potential sale value.

Khudainatov's attorneys refuse to pay the ongoing maintenance costs as long as the government pursues a sale and forfeiture. However, they say their client will reimburse the U.S. government for the more than $20 million already spent to maintain the yacht if it's returned to its proper owner.

In court papers, the government says Kerimov disguised his ownership of Amadea through a series of shell companies and other owners. They say emails between crew members show Kerimov "was the beneficial owner of the yacht, irrespective of the titleholder of the vessel."

The emails show that Kerimov and his family ordered several interior improvements of the yacht, including a new pizza oven and spa, and that between 2021 and 2022, when the boat was seized, "there were no guest trips on the Amadea that did not include either Kerimov or his family members," according to the court filings.

The government also says Kerimov has been trying to sell Amadea for years, so a sale would be in keeping with his intent.

"This is not a situation in which a court would be ordering sale of a precious heirloom that a claimant desperately wishes to keep for sentimental reasons," the government said in filings.

Even if Amadea were sold quickly, the proceeds wouldn't automatically go to the government. Under law, the money would be held while Khudainatov and the government continue their battle in court over the ownership and forfeiture.
