My friend's mother is a divorcee.Since my friend's birth she has been staying with her mother in her grandfather's house( maternal).She is now 25 years old.Financially they are not strong enough to shift elsewhere. Recently however they have come to know that her grandfather has made a will where he has given everything to his only son.Her mother has 3 elder sisters as well, who are married.Now my question is whether there is any law in favour of my friend's mother under which she can claim her rights to her father's property?Does she have any such right?Please suggest.
