Dear Sir, I am fom M.P , my father died when i was 4yrs old and I have a sister who is married and mother . My father had left a plot on which later house was built by my mother. the house in her name. I want to know that what is my right on the property. My mother is a money minded person so I want to know legal procedure also. Also there is some grandfather's property and they have also died , no one is answering property related questions so I want to know my right on this property also and what legal action I can take to claim it. I am the only son and none of the properties are in my name , so I want to know my right and legal process to claim it.
