Billionaire SK Group Chairman Chey Tae-won was ordered to pay his former wife 944 billion won ($644 million), well below the amount she sought.

Since then, Roh’s fought for a bigger slice of his fortune, arguing in multiple court cases that her father contributed to the company’s growth with an early investment.
