Property Issue

Hi, I am a Sikh, who is living with my wife and son, my father also stays along with us. My father and mother are separated but not divorced, and stay separately. The property which I stay in belongs in a joint name between my father and me, and there is a loan tenure which is split between my father and me. Since the last 10-15 years all expenses of the house, including maintainance, renovation, have been borne by me. The question is can my father sell the property without my approval.
