My step-son is 19 now, he lives with us. He dropped school, does not work and does not want to. He behaves impolite, rude, speaks course language, yells at everybody in the house, continuously breaks house rules. our younger child sees all this disrespect and learns. Tension in our home is about to turn into mutual hatred. I do not want the older one to live with us anymore. What does law say about this situation? Is there a legal way to force him out of our home?
