Process to obtain a Relinquishment deed

This is in reference to mutation of property without a will. My father passed away in June. He left a home and a plot. Both are in his name. My mother and I are staying at the home and my sister is married. She is a homemaker in Bhopal. I have turned in the paperwork for mutation of the land but not for the home yet. Eventually we are going to sell both the properties. Some people told me that I should have got a Relinquishment deed from my sister before submitting the paperwork so that she doesn't have to come during the sale procedure. My sister and I don't have any dispute and I strongly believe that she has equal share in both the properties. It is just that I would like some legal guidance on the procedures. Can I get the our home transferred to our name before getting a Relinquishment deed from my sister? She cannot come down to Nagpur for 3 months because of some personal reasons.
