An update - last month I got another letter through my letter box, this time I put it back in a postbox unopened with return to sender addressee not6 at this address in large letters. Subsequently, yesterday I got another letter from and address in Oxfordshire. I've written the same on the envelope and will be returning this unopened.

So, what if this is a summons, and what would happen if the person does not attend court - the fact the police seem to be writing to my address, whoever it is wouldn't have received the correspondence.

Then if whatever court makes a judgement in his absence, and he doesn't pay, how will I know for certain that the Bailiffs won't kick my door down?
