am i supposed to pay rent unpaid by my father

My family stays in a rented house, rent of the house is 7.5 thousand. My father agreed to transfer house rent every month to owner account , from last 1 year he did not transfer rent amount and owner did not check it. Now owner came to know that my father did not pay the rent, he is demanding amount in single pay. My father is a pensioner he gets 17.5k per month as pension, i am jobless and my brother recently got job and my mother is housewife. My father owns a land of 2.5 acre value app: 1 lac, my question is what will happen if owner proceeds legally to get back his rent. Am i suppose to pay rent as i stayed along with my father as well?
