Former Hanjin Shipping chairwoman Choi Eun-young has received an 18-month jail term for insider trading.
The 55-year-old was found guilty at Seoul central district court of selling off her family's stock in the defunct shipowner just before it filed for a court-led restructuring in April, 2016.
She was also ordered to pay a KRW 1.2bn ($1.09m) fine and forfeit KRW 503m, the Yonhap news agency reported.
The court said however that the share sale did not look to have been planned in any great detail.
She was charged last December for selling stock belonging to her and her two daughters, avoiding KRW 1bn of losses.
Choi is the wife of the late Cho Su-ho, the younger brother of Hanjin Group ghairman Cho Yang-ho.
She ran Hanjin Shipping from 2006 until 2014 after her husband's death.
Choi pledged KRW 10bn to help the struggling company before it collapsed.
