I'm a 56 year old male, semi retired. I came home one afternoon from work and found my 27 year-old stepson starting a small fire to burn some dead vegetation in front of our house. It was next to the wood siding on our house. I took a garden hose to put out the fire. He grabbed the hose out of my hand and drenched me completely. Then, after I turned off he water, he grabbed one of my legs from behind and flipped me to the ground. I landed on a shoulder which had sustained a torn rotator cuff 2 years prior during a baseball game. All during this time, he was screaming his head off at me so that he entire neighborhood could hear it. I called the police and hoped to get him out of the house permanently. The police told me that I would have to press battery charges, they would arrest him and then it would end up in court. My wife owns half of this house and apparently sees nothing wrong in any of this, and is very protective of her son. The police told the kid to get out of the house for a few days, wrote a report and left it at that. I want this kid out my house permanently. He works part time, 4 hours a day, contributes nothing to the household, and has a serious chip on his shoulders. How do I get this 27 year old deadbeat out of my house legally and permanently?
