we have a house which was bought by my grandfather in 1964, my my grandfather has 1 son( my father) and 3 daughters. One of my aunt became widow in around 1975 and my father bought her home with her son. My father took good care of her all these years also taking care of all the expenses of my aunt as she was not having any source of income. My grandfather died in 1980 and grandmother in 1989 without leaving any will. We are living on the ground floor and my aunt is living on the 1st floor with her son. Now she has filed a lawsuit against us seeking partion of the property .
Please help me on this can daughter as for partiton of a dwelling house, if yes then is there a loophole.
