What was the dispute between ex-Raymond Chairman Vijaypat Singhania & his son Gautam?

Raymond Group's ex-Chairman Vijaypat Singhania, who passed away aged 87, handed over all his stake to son Gautam in 2015, which later led to a legal dispute. Vijaypat accused Gautam of betraying him by usurping his property and forcing him out of their house in 2017. Gautam later tried to block the publication of Vijaypat's autobiography 'The Incomplete Man'.
