Residential

Hi ..i m a married woman living in my in laws House. I was married in 2016. Both My husband a his father are business men. But their field of business is different. Both me and my husband are being mentally tortured by my in laws parents for 3 years. They always threat us that we have to leave his house if we do not follow their rules. My husband has just started his business. So he is unable to move to a new house. My in laws parents are using this opportunity to make us frighten every day.. sometimes we protest against them that we have the right to stay here. But now my father in law informs us that he will sale this house which is an ancestral property on his name and we have to leave from here as it is on his name. They live in the ground floor and we live in first floor. My husband has contributed so much money to make our bedroom; dining room and bathroom in the first floor. My question is according to law what are our rights? Can i have the right to stay here or we have to move from here.
