text: A contract needs to be in writing and signed to be binding. Who's to say that you didn't create the e-mail and send it to yourself.\n\nIn California, your lease agreement automatically becomes a month to month contract if the lease expires and is not renewed and you pay July's rent and it is accepted.\n\nYou're not responsible for finding a tennant and you're doing her a favor by doing so. However, here is how I would approach it:\n\nI would tell her (via phone and through a certified letter) that you plan on leaving August 15th and you're willing to pay rent till August 15th. You're also willing to be flexible when showing the place to potential tennants. You'll even place free ads on the web and at your workplace to help her out. Tell her that she can use your cell phone number as a contact in any of the newspaper ads that she places and pays for to facilitate the renting process. Do not sign any lease or document that states that you're responsible for rent beyond August 15th.\n\nNow while you're talking to her on the phone and if she refuses, it's time to play hardball (do not put this in writing).Tell her because of the financial stress of finding another place till August 15th, the alternative would be for you not to pay July's rent, not to sign anything and not be flexible in showing the place. Tell her that she will need to evict you and you will fight it in court. Tell her that she might win, but it will cost her money and time and you are willing to put everything into a storage and rent a room for a month or stay at your cousin's house once you are evicted. \n\nYou're basically making her an offer that she can't refuse. Also, if you lose the eviction, your deposit will be used to pay July's rent and you just need to pay for the days up until you got evicted. \n\nI own a few rental properties in California and if I was a renter, I would approach it in that manner.\n\nGood Luck
