Is it legal for a landlord to send a notice of eviction through the U.S. Mail. I'am not sure of any of the Pennsylvania eviction laws, and I was sent a notice of eviction through the mail the post date was 10-23-06 but I didn't receive it until 10-28-06. It gives me until 10-31-06 to pay back rent, or be served by a magistrate to vacate immediately. I have lived here for 14 years in the same apartment with my daughter and have never had this problem before, until recently becoming disabled and unable to work. Please any advice would be most appreciated.
P.S. I do not have a written lease with this landlord if that makes a difference, thank you.
