Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
If the entire money of your father is (Haram) ill-gotten, then it is not permissible for you to benefit from anything of it unless you are in necessity.
If you do not have money or you do not earn enough for your necessities of food, drink, clothing, and housing, then you are permitted to benefit from his money and whatever he buys with his money according to the necessity.
However, if you can meet your needs with permissible money or permissible earnings, or you have a husband who spends on you, then, in this case, it is not permissible for you to benefit from anything of his ill-gotten money.
This is based on the assumption that what you mentioned is true, that the entire money of your father is ill-gotten; even though it is unlikely that the entire earnings of a Muslim are ill-gotten.
You have to advise your father in a gentle and soft manner and warn him about the consequences of forbidden earnings, so that he may repent to Allah and stay away from what is forbidden.
Allah knows best.
