For example total cost of property id Rs. 100/- and the property is registered on your and your father's names so you are undisputed owner of Rs 50/- now out of remaining Rs. 50 which was your late father's share you 3 i.e you, your mother and your sister are equal equal right holders in absence of any will.
but if the said property is purchaced by your father as sales proceed of your ancesteral property and he just mentioned your name in property titles, then situation may be different. if it is proved by any means that you didnt contributed in purchace of that property and the peoperty was solely purchaced by your father with sales proceeds of your ancesteral property then your sister will have the same rights as yours.
regarding your mothers behaviour (which is hard to believe) you can inform to police about such threats with proofs. this may save you in case of any untoward situation. Ask your relatives to mediate and resolve the issue amicablly.
