Daughter's right in grand mother's property

Your mother in law cannot deprive the children. She cannot write a will because she has inherited it. All your mother in laws children will inherit the property equally. your mother in law cannot deprive the daughters of their share.

Dear Mr.Anil Kumar Menon,

Thanks for your reply.

With regards,

Ravindra

Sir,

Pls calrify if her son ( my mother in law's son) manages to get her signature to take the entire property in his own name, is it legally valid?

Now he wants to construct a small room on top( already 3 bed rooms both in ground & first floor each)  probably to show that he has invested in it  or  to show expenditure on it, will it have any bearing on the heirs( daughter's share)

Thanks

Ravindra
