<prompt> Human: So, about two months ago i came home to an official city notice on my door that the property we are renting was to be purchased from the landowner. This is because our apartment complex is sitting on a fault line. Yesterday, the landlord showed up with a three day notice to pay a total amount of 4350. My parents are planning on just not paying, but they dont understand that its not that simple. They signed a lease and refuse to show it to me. What can i do?x200B;EDIT: Yeah, parents havent been paying rent.x200B;  <response>: Did your parents stop paying rent 2 months ago when they saw the notice on the door?
