This is not as easy as it sounds. We bought our house new. We have been the only ones to have lived in it. We tried to sell by owner a few years ago and someone who came through on an open house used our address to get a driver's license, checking account and who knows what else. After the Sheriff's office told me they were hunting this person, I went to the post office to stop the deliveries of this criminal's mail coming to our house. The post office was not at all helpful, but filled in the forms that only mail with our last name on it would be delivered. Now we not only get the original huckster's mail we are getting someone else's. Our address, their name. The USPS assures us the original 'do not deliver' order is in force.
I am truly sorry to hear of the trouble you have.
In this case, the man was renting the home from his landlord whose son was using the home as his mailing address. The renter could have informed his landlord about his own son and if that was not good enough then threaten to move out.
I know I would have. If I am the one paying expensive rent for the home, it would be unacceptable to me that another would use the address for mail.
And considering the trouble we know this guy had from it, he would have been better off if he had sought to put an end to it or move.
But who knows, maybe he will get his million dollar lawsuit for being put on the grass. No wonder he is crying to the Drive-by Media blaming the police for what is at least half his own fault.
Heck, I should be so lucky. LoL!
