Wife claim in inhabited property

HI All,

I am in the process of getting divorce from my wife.( No legal process started yet)  Just few question-

1)- Is she is having any claim of my father's or Grandfather's Property?

2)- She wants 50% share in the house which is on my name. But i took money from my father to purchase this House. So in this condition can she still claims her share in this hose.
