How to get phatta which is in my father's name

I got a piece of land by way of a registered will. It was originally a government poramboke land as per RSRS 1911. Nobody was occupied during that period. Later my father occupied a piece of land. During 1970 to 1988 Town survey was carried out. One old survey field was split up into 78 fields and a survey field was registered in my father's name in the Town Survey Field Register. But in old survey No. a temple name was entered in A. Now Tahsildar has not given patta to my land. How can I get the patta for this land.
