What is the dispute over 'Jalsa' between Amitabh Bachchan & his sister-in-law Ramola?

The dispute over Amitabh Bachchan's 'Jalsa' bungalow stems from a 1993 deed, which transferred its ownership to his wife Jaya. Bachchan's sister-in-law Ramola Bachchan has filed multiple complaints over seven months, claiming she never consented to the transfer. Ramola alleged that attempts have been made to remove her name from Maharashtra government's Property Card and replace it with Jaya's.
