The Seoul Central District Court ruled this afternoon that Choi Soon-sil will have to serve 20 years in prison, pay 17 million dollars' worth of fines and forfeit nearly 7 million dollars more.
Choi Soon-sil might have thought that her problems were behind her when the former president of South Korea, Park Geun-hye was deposed a year ago.
Choi, 62, was arrested and indicted on 18 counts of corruption in November 2016.
The court acknowledged that Choi colluded with Park to extort money from the conglomerates including Samsung, Lotte and SK, using presidential connections and abusing power.
The court ruled yesterday that the 3.65 billion won Samsung spent to buy horses and equine equipment for Choi's daughter, and another 3.6 billion won it paid to a company controlled by Choi, amounted to bribes for her. Choi received a three-year prison term last June in a separate case related to influence-peddling in university admissions.
Shin was also fined 7 billion won.
A Seoul court jailed Lotte Group Chairman Shin Dong-bin for bribery, leaving the nation's largest retail group leaderless as the conglomerate seeks to navigate a planned initial public offering of its hotel unit and China relations threaten the sale of a chain of stores there.
Shin was immediately put under custody in the courtroom.
Reading out the verdict, the judge said Park "abandoned constitutionally-given responsibility and gave position and power to others" and that Choi used her position "to monopolize state business and seek personal gain".

The outcome of Choi's trial is seen as a preview to Park's trial, as she was labeled a co-conspirator in 14 of Choi's 18 charges, in addition to her own.
Choi Soon-sil, friend and adviser to the disgraced president Park Geun-hye, was convicted of soliciting bribes from companies including Samsung. As for the former senior presidential secretary for civil affairs, Woo Byung-woo - his sentencing, originally planned for Wednesday, has been postponed to next Thursday to allow more time for reviewing documents.
In passing the sentence, the court found Choi guilty on a number of charges, including bribery, coercion and abuse of power.
Samsung Electronics Vice Chairman Lee Jae-yong was released on appeal as the higher court cleared him of major charges and handed down a suspended sentence.
The "female Rasputin" at the heart of the corruption scandal that brought down a South Korean president was sentenced to 20 years in prison today in the latest in a series of sensational criminal trials. Park denies any wrongdoing.
