I jointly own a residential property along with my mother in Mumbai purchased in 2009 at 50 Lacs (todays cost 1 cr). The 100% financial contribution for the purchase and home loan EMIs has been from my salary. I had inserted mothers name as joint owner out of just love and affection without she contributing anything financialy (she is a housewife without any pension)
Today I need to transfer her 50% ownership to me as I have younger brother too. Which option should i choose between release deed and gift deed so that I have to pay minimum stamp duty. Also would release deed/gift deed attract any capital gains and how much.
