I'm a regular reader of cases in this forum....
1. Accordingly to article no# 21 in the Constitution Of INDIA ever individual has a right of speech of freedom.
2. Mother and Father Both has right on Son Property as far as I remember I have read somewhere as well it is only when Both don't have a shelter and any income for surviving in this world.
Here father is dead only mother is alive and has property on her name and also getting pension as mentioned above..(even after getting pension & having property).
3. However as per my understand where mother has a property on her name (SHELTER) and also getting pension from the Govt she already has ample of money to survive in this world.
If she has to claim for property why an't she claim her right in other son and daughter's property why is she claiming her right in Deceased son property who has left a wife and daughter behind. Instead of taking care of Daughter in Lay and Grand Daughter she is playing such king of tactics in this old age is also ashamed for her self.
4. If i would have been there at your place I would have asked the person in court the following questions...
i) Why she need a share in my property.
ii) What she will do with that share.
iii) If incase she need shelter and want to earn extra income by giving her property or deceased son property on rent then she can live with her daughter in law and grand daughter and give her properties on rent and then she can earn extra income from there as well. Why the share is required in her Deceased Son property. After all one person need how much space to live her life. (1 room to sleep one common drawing room to sit and rest room, a part from that a single person can only eat 2/3/4 chapaties at a single point of time).
What else is required these things her daughter in law and her grand daughter can also give her and also they can take care of her mother in law/grand mother. I'm sure at this old stage of time where the mother is getting pension may also be getting medical facilities from CGHS or from other health service department as declaired for her.
I don't think so that what ever I have mentinoed is against the Law or against any person individual. It is my thinking which I have shared after reading such blog.
