Teodorin Obiang was charged as part of a corruption probe launched in December 2010 to determine whether three long-serving African leaders used corrupt means to acquire expensive properties in France.
The investigation focused on Congolese President Denis Sassou Nguesso, late Gabonese president Omar Bongo Ondimba, and the Obiang family.
French authorities have already seized the Obiang family’s six-storey mansion on the chic Avenue Foch in Paris as well as several luxury cars.
They also took away vanloads of possessions including paintings by famous artists, a clock worth an estimated three million euros ($4.2 million) and wines worth thousands of euros a bottle.
Nine seized cars, including a Maserati, a Ferrari and a Rolls Royce were auctioned in July last year and netted 3.21 million euros.
Oil-rich Equatorial Guinea has been ruled with an iron fist by Teodoro Obiang Nguema since 1979.
