Ganesh Kumar and his wife Yamini moved a joint divorce petition in the family court at Thiruvananthapuram on Thursday.
This issue, taken up by the CPI-M, led to unruly scenes between the government and the Left opposition in the floor of the Kerala assembly.
Kerala's Forest Minister Ganesh Kumar was forced to step down following allegations of domestic violence by his wife.
As questions were raised on his continuance in the Cabinet, the actor-turned politician put up a brave face and scotched speculation he will quit.
Ganesh was recently in the news for allegedly being beaten up by his lover's husband.
