Do I have a legal claim to my mother’s house?

I have one younger brother. My father expired in 2008. My mother became a legal heir and got his pension and gratuity etc from his office. With that money she purchased a house in 2010. In 2014 I got a job in my father's office on compassionate grounds. Do I have any share in the house purchased by my mother using my father's death benefits, or not?
