According to PEOPLE, Maddox has even begun mastering the Korean language so as to fully prepare for his big move away to Seoul.
While some sources say mum Angie is "proud" of Maddox's move overseas, others report that tumultuous split and ugly custody battle between Brad, 55, and Angelina, 44, all but forced Maddox to make a geographical change in his life.
Last week, New Idea reported Brad and Ange's divorce battle had moved on from their kids, and to a French Chateaux.
"It’s the final sticking point,' a source spills to In Touch. "At first it looked like Angie wasn’t going to fight him on it – it was his dream project and he fell In love with it – but suddenly she changed her mind."
The source goes onto claim that Ange is stamping her foot down in a bid to ‘twist the knife in further’.
"Brad loves that place and she’s realised how much it would drive Brad crazy if she took it from him," they add.
The former couple is yet to respond to the claims.
Angelina and Brad share six children, Maddox, 18, Pax, 15, Zahara, 14, Shiloh, 13 and 11-year-old twins Knox and Vivienne.
