text: Just send it to her "last known address"  and write "please forward if necessary......send a couple.......best case would be to send it certified "return receipt", but I don't know if the post office will automatically forward certified mail.....\n\nHer last known address is legal for small claims purposes and you can appear in court and most likely win a default judgment very easily....just document that she purposely and willfully is hiding her current address from you....Judges hate landlords.
