The son of a billionaire oligarch was ordered to pay his mom $104 million in damages Wednesday by a London judge, who found he tried to help his dad hide assets in his parents’ divorce, according to a report.

Temur Akhmedov allegedly worked with his dad, oil tycoon Farkhad Akhmedov, to cover up the older man’s lavish assets, such as a $400 million superyacht and a massive art collection, so mom Tatiana Akhmedova couldn’t get her proper cut after the couple’s 2016 split, the Guardian reported.

The judge in the case ripped Temur as “a dishonest individual who will do anything to assist his father.”

“All happy families are alike, each unhappy family is unhappy in its own way. With apologies to Tolstoy, the Akhmedov family is one of the unhappiest ever to have appeared in my courtroom,” judge Gwynneth Knowles added in her written ruling, in a reference to Leo Tolstoy’s Anna Karenina.

Farkhad Akhmedov was ordered in 2016 to pay Tatiana $631 million, or 41.5 percent of his fortune, in their divorce — which is among the most expensive ever recorded.

So far, though, Farkhad Akhmedov has only paid about $6.9 million, which brought on Tatiana Akhmedova’s court action against her son. 

Temur was reportedly accused of acting as his wealthy dad’s “lieutenant” to help hide assets.

In addition to the boat and art, he also allegedly tried to conceal multiple mansions a helicopter and $150 million he put into the stock market for his dad, the Guardian said, citing court testimony. He even admitted losing $50 million in one day of trading while studying at London’s School of Economics, the paper said.

Akhmedova hailed the ruling Wednesday.

“Today’s judgment is the inevitable conclusion given Farkhad’s failure to behave honorably in the first instance,” Judge Gwynneth Knowles agreed. 

“Temur has learned well from his father’s past conduct and has done and said all he could to prevent his mother receiving a penny of the matrimonial assets.” 

For his part, Temur Akhmedov tried to play nice, though he did not agree with the ruling.

“He would consider it a price worth paying for should it lead to a reasonable settlement between the parents he both loves,” His spokesman told the Guardian.

“Never sought to take sides or get involved but inevitably found himself sucked into the vortex of a bitter family dispute.”

There seems to be no love lost between the mother and father.

Farkhad Akhmedov said in a statement, “Entirely predictably, given its original wrong and misguided judgment, the London court has ruled in favor of visiting ‘the sins’ of the father on an innocent and loyal son.”
