Teodoro Nguema Obiang, vice president of Equatorial Guinea, had a superyacht and two lavish homes seized by South African authorities.
Following the success of a lawsuit against Obiang for unlawful detention and torture, local businessman Daniel Janse van Rensburg won the court's order for the seizures.
About $2 point 2 million (£1 point 8 million) in compensation has been sought.
He claims that after a business deal went south, he was wrongfully imprisoned in Equatorial Guinea for about 500 days.
The son of the world's longest-serving leader and vice president has not yet offered any commentary on the situation.
It has long been alleged that he and President Teodoro Obiang Nguema Mbasogo viewed the oil-rich nation of Equatorial Guinea as their private fiefdom and abused its wealth and resources.
This judgment is the most recent in a line of judgments handed down against him by courts all over the world.
We joined two homes. in Cape Town in a formal application two weeks ago, and the superyacht last Tuesday," the businessman's attorney Errol Eldson told AFP.
He added that a request had been made to put the assets up for auction.
Since his "harrowing incarceration" at the infamous Black Beach prison in 2013, Mr. Van Rensburg has fought a protracted legal battle against the vice-president in South African courts and written a book about how a business trip to Equatorial Guinea in 2013 "turned into a journey to the depths of hell.".
According to Mr. Eldson, his client had planned to launch an airline in Equatorial Guinea with a local politician, but at the last minute, he pulled out and demanded a financial reimbursement.
Following the argument, the politician called Vice-President Obiang, and "within 10 minutes," according to the lawyer, an elite security force unit "picked Daniel up and threw him into Black Beach prison.".
It is widely believed that Obiang is being prepared to succeed his father, who has held the position of power for 43 years.
He ordered the arrest of his half-brother last month due to the sale of a jet.
It was claimed that his half-brother stole the sale's proceeds. He has not responded to the accusations in the media.
The vice president, who is renowned for leading a luxurious lifestyle, has also run afoul of the law on occasion.
A $30 million Malibu mansion and other assets, including a Ferrari car, were seized by US authorities in 2014 on the grounds that they were brought in with the proceeds of corruption.
Swiss prosecutors seized 11 of his high-end vehicles two years later. The automobiles, which included a Bugatti, Lamborghinis, Ferraris, Bentleys, and Rolls Royces, were auctioned off for about $27 million.
In 2021, he was also fined and given a suspended sentence by a French court for using tax dollars to support a lavish lifestyle there. He refuted any wrongdoing.
The UK imposed "anti-corruption" sanctions on him that same year.
He allegedly owned a collection of Michael Jackson memorabilia, which included a $275,000 glove covered in crystals that the late singer wore during his 1980s Bad tour.
The new sanctions, according to the UK, are directed at people who "lined their own pockets at the expense of their citizens."
