Property purchased from father-in-law giving agreed price

I have purchased one land along with a building from my father-in-law one year go through sale deed. I have paid him the agreed price and off course the registration charges as per the valuation. I have the PATTA on my name. It's a non ancestral property. I have allowed my in-laws to enjoy that property. However, I have not transferred the electric meter or gas on my name. I don't have anything on my name except the sale deed. Would it create a legal issue in the future? My father-in-law is having 2 more daughters. Is there a possibility that my father in law would reclaim that property on his name after a few years if he would continue to enjoy in my property ? I am living outside the state. Is there any precaution that I have to follow? Please advice.
