fake will and property transferred into my grandmother's name

there has been one more will apart from my grandfather's registered will made by my grandmother who is just a housewife and got it registered as well by bribing lawyer and sub registrar and property has been transferred from my grandfather's name to my grandmother's name for the entire building . My father is mentally ill and my grandfather in his will has directly made me the owner when i was 3 years of age stating that i get first floor and half of second floor. he has also said that no changes shall be made during my minority . but my grandmother has created a fake will declaration where she has claimed that my grandfather has given written instructions to change the will which is false and i have also not seen any written instructions given by him and she has got it transferred into her name . now does court partition the property if i file section 471 or it just punishes my grandmother for fake documents?
