The wills and some of the emails which are a part of the charge sheet stated that Indrani had bequeathed around 20 properties to Vidhie.
"The wills were drafted to the effect to ensure that Vidhie gets the properties when she turns major," said the charge sheet, filed on November 19.
"Of couple of other things, I will be writing to Richard Harris and Pablo to add Vidhie's name to SneydPark and Malambo (properties in United States) when she is 18," wrote Indrani to her husband Peter, also a co-accused now, in one of the emails.
The email also spoke about adding Vidhie's name to properties in Delhi, Goa and 19 other properties.
The charge sheet said that Indrani, who had a soft corner for Vidhie, feared that the entire property might go to Sheena and Rahul if they were married.
"In this context, she planned a conspiracy with Khanna and her driver Shyam Rai to kill Sheena Bora," the charge sheet added.
