Legal Question in Landlord & Tenant Law in California

First off, you can ASK for anything other than asking someone to commit a crime. So you can always ask to negotiate an early move-out. As for whether you can make them move out, that depends on when the verbal lease started. A lease of more than a year is invalid if not in writing and signed by the parties. If the lease was for less than a year, or even exactly a year, then they have an enforceable lease that you cannot legally break.
