My mother was my dad's second wife. He passed away 7 Years back (in 2005). My father's first wife (married in 1972) was my mother's own elder sister... she have three daughters (all married). My father married my mom in the year 1982 without giving divorce to his first wife. I am the only son (unmarried) from the second marrige. Now both the widows and I are living in the same house. The First wife and her daughters wants to sell the house/ property and take their share. Unofficially second wife and her son are living in the first floor and the first wife is living in the ground floor. Do the second wife and her son have any right over the property. What legal action can I take if I am not willing to sell the property now?
P.S. - First wife and her daughters are constantly harrasing us since last 7 years.
Please help me out. I am ready to share the property with them but I need few years time.
