SK Group Chairman Chey Tae-won, left, and his ex-wife Roh Soh-yeong arrive at the Seoul High Court, June 26, for a hearing in their asset division case.

Yonhap SK Group Chairman Chey Tae-won was ordered Friday to pay 944 billion won ($644 million) to his former wife, Art Center Nabi Director Roh Soh-yeong, in a retrial of their high-profile property division lawsuit.

The Seoul High Court handed down the ruling during a hearing, concluding the latest round of the long-running dispute over the division of the couple's marital assets.

The court treated Chey's stake in SK Inc., the group's holding company, as property subject to division.

The court said a third of Chey’s share property is subject to Roh and two thirds to him.
