Advice: How can I throw my father out of the house legally

My father has 2 wives. I am the son of the first wife. We are 3 brothers. My father's second wife has 6 children. So far, he hasn't divorced my mother. He has many lawsuits against him. As far as I know, 2 counts of murder. He went with his second wife for the last 30 years. His second wife died 2 years ago, and now she is moving with my mother into our house, which we built 2 years ago. But I don't care. I didn't want him to live with us but unfortunately my mother wanted him to live with us. The land on which we built the house was named after my grandmother (my father had 4 brothers). The main problem is that he has a habit of scolding everyone every day. 


My son, wife, and younger brother didn't want him to live with us. We don't feel safe unfortunately my mother did. He even beats my mother sometimes. 


I fear for my life and my family's life if I argue with him. Please tell us how we can get him out of our house
