My father has his owned a self acquired property of an Industrial Plot.
He left behind four married daughters with no Son, Wife and his old widow Mother (my Grandmother).
My father has one married younger Brother; living separately with his family after Legal Division of Property by his father (my Grandfather).
My Grandmother is getting a good pension, living with my mother - father's home; under supervision of my elder married Sister financially as well, who is Government Nurse.
My Grandmother never gives her her pension nor my mother ask for it in any domestic expenses, my mother do not have any certain income.
My Grandmother is claiming Property Rights in my father's self acquired property on the Grounds that her money is also invested in the Property - She gave money to my father.
The fact file is that my father didn't took any such loan from his parents but he got her four sisters and brother married by taking frequent loans.
We are afraid that my Grandmother is claiming her share in my father's self acquired property. Her legal heirs will be her daughters and son after her death which will bring more Legal Complicacy in my father's property.
Can we prove that my Grandmother is not dependent of my father due to her husband Pension, when she already having second son alive...?
How we could avoid that situation...?
