My question involves juvenile law in the State of: New Jersey

My brother is 20 years old. He still lives at home, just graduated high school and has a part time job. The problem is he doesnt provide any time of income or help out around the house. Its unfair because we are 4 people living in this house: me, 16 years old, my 2 brothers who are 20 and 24 years old, and my mother. She also only has a part time job and my oldest brother helps her with the bills while I do chores around the house. My middle brother refuses to do both, not the mention that he has no respect for anyone in this house including my mom and oldest brother. He eats, sleeps, and messes up the house and everyone else has to provide for him. MY mom has given him 2 months to save up money and move out and he refuses to do so. The only solution my mom can think of is to call the police and forced him to move out.
