How Do You Stop Mail For A Deceased Relative?

There may be different steps according to the state you are in. I would consult the post office in the area where the deceased lived. If they are unable to help, I would write deceased on the envelope and return to sender.

You can stop alot by going to the DMA web site and register for $1 which is direct marketing association it take about 3 months to see results. You can also have the mail redirected to go to a executor or adminastrator you can do that right at the post office

You need to go to usps.gov
