"If, for instance, your adult child has been arrested, do NOT intervene this time. If your adult child lives at home and is involved in anything related to drugs, alcohol, crime, violence, unacceptable behavior, or any type of illegal activity whatsoever, insist on his immediate departure from your home. Call the authorities if necessary. He can choose to go to rehab or to a friend's home, or anywhere he'd like, including living on the street--whatever he decides--but it is NOT your responsibility to find somewhere for him to go. Remember, if he has broken the law, you may be considered an accessory to his crime. Calling the police will be one of the hardest things you'll ever have to do, but it may be necessary."
"If your adult child lives outside the home and is calling for money or a place to live, or is requesting (in many cases, begging) for your signature on a contract or rental agreement, do not give it to him."
