Mean neighbor issue

Are they illegally parking? If YES, call the police. If NO, I don't think there is anything you can do to force them to park elsewhere.

Dear neighbors are mean people: I suggest you and your mother consult with a nearby attorney. Make sure you have tangible proof (photos are good) that the neighbor parks across the road in a manner intended to delay a senior citizen from exiting her home. Your lawyer may be able to determine whether there is a local parking ordinance that may help your mother. You may also consider that your mother may gain maneuverability with a smaller vehicle. The law has not found a remedy for the obnoxious neighbor. Perhaps you might decide to take command over the space directly across from your mother. Maybe you could park your vehicle there and deprive the neighbor of his need to be abusive to your mother. Your mother may also decide to park in the unused space at the neighbor's house. Good luck.

First talk to the neighbor no matter how mean. if this doesn't work, ask a lawyer to write a letter on "elder abuse." Not exactly on point, but if he is deliberately preventing your elderly mother from getting out of her home, it could be seen as a form of harassment. What if she has an emergency? If he has an alternative place to park, there's no reason for him to continue doing this. Also, do check the parking rules in your town. He may be in violation, esp. if he leaves his car there more than 72 hours. Good luck!
