What is the name of your state? California - We were sent a notice to vacate then we paid our rent for time after and it was not refunded? However they state they sent it back certified but we were out of town and letter was sent back to them - That was in late April they still havent sent it back ? What can we do now. Their lawyer called about signing a stipulation and they have sent notices that they only want possesion no lawyers costs etc. So what is a stipulation?
