Can i claim the stamp paper fee which i paid to the court

I have a question. I have been granted a Succession certificate to claim all the dues of my late wife. which includes the company where she was working (Gujarat Alkalies and Chemicals Limited, a semi govt. Gujarat company) and India Post. For the entire amount I have paid an amount of Rs. 75,000.00 as a court stamp fees Court has clearly mentioned and ordered Post office to pay the amount to me. later on came to know post office has paid the entire amount to second name holder. This account had 2 names first was my wife's name and second was my sister in law. We had proved in court the entire amount was brought by my wife. Know if the post office has paid the full amount to my sister in law, my question is what about the stamp paper fees i paid to court to claim this amount? Can i get back my money?
