My question involves a roommate in the State of: California

We have a short-term, month to month lodger and house was foreclosed on. Lodger is demanding 'keys for cash' and 90 days free rent. Lodger has changed the locks and refuses us access to property. Police were called. Polce said we needed Restraining Order from court.

HELLLLLLLLLLLPPPPPPPP!!!!!!!!!!!!!!
