My father in law is the only son to his parents and ther is a property in the name of my father in law's mother. Now my father in law and his parents are no more. My mother in law is there. my wife has 2 sisters and one brother and all are married. My mother inlaw requested a release dead in my father in law's mother's property and all 4 ( 1 son and 3 doughters) signed the release dead in favour of my mother in law to enable her to get some loan etc to clear debts. This was 12 years ago.My father in law and mother in law are govt servents. She received all money of my father in law's retairement benifits after the release dead and clear those debits.Now that property converted in to apratment by joint developement and she (my mother in law) has a share as one flat in that aprtment. (past 4 years) My question.
1.Is my mother in law can execute a will about that propoerty to his son?(whole property) In that case can my wife and her sisters (doughters) has any right to claim?
2.Is this property consider as ancestral property or my mother in law's own property because of the rlease dead?
3.As per the release dead she paid each 1 lakh but never paid.
4.We are christian family.
