rectification of our property

dear reader I am writing this to seek a legal advice from the expert. My query is related to our property which has been registered in the year 1985 and the person who registered it was my father and he died in the year 1993. The property in question is 172 square yards but recently when we measured it. the property now after measuring is of 325 square yards. now I want to rectify this property to 325 square yards I tried to find a solution for this rectification but there is no one who is coming forward to do the above. my query is how to get this property rectified because every person to whom am approaching he is asking the persons presence who had made this registration that means they want my dead father to be present at the registration. This property is an ancestral property when I got the encumbrance. according to the encumbrance we cannot find any prior records of this property it means you don't find any prior owner registered other than this gift deed which is made by my father to my mother. and the property is registered under the registration act is registered under the properties act. please advise
