My mother is in her late fifties, with two young kids ages 9 and 10. My brother is 35 years old and has always been the black sheep of the family (due to his own bad choices in life). He's never went to college and is and has been unemployed for nearly his entire adult years. My brother has a nasty temper and violent tendencies. He's threatened to kill every one of his family members and thus burned all his bridges with us.
His on and off girlfriend convinced my mother to let him move into her home for the promise that she would stay and live there as well and that he has changed. The girlfriend lives with her parents but my brother is not allowed in his girlfriend's family home because they are afraid of him as well. My brother and his girlfriend decided to have a baby, so my mom thought he would change for the better for his newborn. It turned out that he will always be the same person, violent, disobedient, disrespectful, and does not clean after himself. My brothers girlfriend also noticed that and decided not to live at my moms house. So now my mother is stuck with my brother.
My mom, her two young children, and my 35 year old brother now live in the house. She's asked me repeatedly to call the police on my brother for domestic disturbance. He raises his hand like he's going to hit her, he yells like a madman at the most trivial things, and occasionally destroys property during his episodes. My mother fears for her life yet is too scared to lawfully kick him out for fear he would come back and hurt her. My brother refuses to find work, he refuses to seek mental help, and he also refuses to babysit or help our kid siblings with their homework. He does nothing to contribute in the household. He previously lived with my father and his wife before moving into my mother's home. My dad won't let him back into his home and he currently refuses to leave my mother's home.
We have another brother who is 28 years old and successful. He's even helped my blacksheep brother with a rental home and paid for all expenses for over a year. In return, the blacksheep brother trashes the house and left it so unsanitary that he was forced to move out.
I don't think he's a bad person, I believe he's just lazy and feels like a failure so he goes on these crazy violent rants to make him feel like a "man." He for sure doesn't want to have any responsibility. He wants everyone to take care of him. I feel bad for him because he feels like he doesn't have a family, but he's the one who dug his own grave. I know he will be homeless if my mother puts him out, but i'd rather him fend for himself than have my mother live in fear in her own home.
My question is, how do i remove an adult child who refuses to leave my mother's home? She is resistant to kick him out for her own safety. I am 100% positive my brother will still show up even if my mom puts a restraining order on him.
