I'm seeking advise on behalf of a friend whose mother has passed away and left a will making him the only heir of a property in Kolkata. My friend's sister wasn't included in her mothers will. (the relationship between mother and daughter was not good) But now she is asking for 50% of the inheritance claiming that being the daughter it is her right and in case my friend doesn't agree she wants to contest the will.
What does the Indian law say in that concern? What are the chances that she will suceed with her claim?
Thank you for your help.
