Lets say that a son owns a house in which he lives with his dad, half-brother and stepmother. At one point that son finishes college and doesnt like step mother, and wants to live witout them. How can that guys throw them out witout unnecessary yelling, fighting or anything...Call police? Or just change lock on the door and throw their stuff outside? How can that be done if its legally his house, but guy doesnt want to do anything ilegal to make them go away???
