2 simple solutions for Ishita's problem

Exercise your right of being a wife and get inside Bhalla house. You would have to deal with Raman's anger here.

Get the police along with media and get whole of Bhalla family arrested except IshRa's kids in the name of getting hold on Raman's properties.

Medical papers can be termed forged but remembrance about Ruhi and Adi cannot. The whole of society, office and business people are aware about Raman's relation with Adi and Ruhi and if brought forth cannot be denied. You can easily state the effects of the banned drug by getting a Psychiatrist and how it was ministered with Mrs. Santoshi Bhalla herself being in the gang and signing the papers and allowing her daughter to carry on this heinous crime. They reminding Raman about every relation but not of his kids and wife. Adi's and Ruhi's mouth being shut by the family by scaring them about their father's death or their father going in coma if his brain is stressed and they believing their extended family blindly. The extended family forcing them to work as Raman's manager and rival. Pihu can be put forth and asked to speak about Simmi's abuse.

Raman will not be able to trust the Bhallas the moment Adi and Ruhi's truth comes out in front of him. The seeds of distrust would seep in and he will have to take a backseat for once.

Once the above step is taken, slowly and steadily IshRa and Shagun can try taking out innocents from the jail . With this , this track would come to an end and also CV's can get their new villian who would like to take revenge from IshRa for being punished even though they were innocent. 😉
