Madhu Kapur, wife of late Yes Bank co-founder Ashok Kapur sold around 0.04% of her stake in the Bank in the open market on September 21.
Shagun Kapur Gogia, daughter of Madhu Kapur confirmed that some shares were sold.
The sale will result in Madhu Kapur's stake reducing to 9.28% and is noteworthy as it comes at a time when Yes Bank co-founder and CEO Rana Kapoor has been denied a fresh three year term by the RBI.
Madhu Kapur has taken Yes Bank and Rana Kapoor to court demanding the right to nominate directors on the bank's board.
Yes Bank shares have lost close to half of their value since the end of August. The bank share ended at Rs 203 a piece down 9.14% on Thursday.
The bench eventually sought the case diaries from state police and reserved its ruling on the issue.
