The only POSSIBLE way to force someone to leave is to obtain a court order, known as an "Unlawful detainer". The landlord files the lawsuit in the local court, has a copy of the complaint and summons "served" on the tenant, and off you go. In Cal it is a "summary process", meaning you may be given a court date of three weeks or so, at which point you and the tenant go to a hearing, where the tenant can provide a "defense" to why they should be allowed to stay. If the court agrees with the landlord, a "writ of possession" is issued, giving the tenant five days to leave before the sheriff physically removes them.
The landlord may also request the court to order payment of the landlord's eviction expenses, unpaid rent, damages to the premises, interest, collection costs, attorney fees, and perhaps additional penalties, depending upon the circumstances.
Note: You could have started the eviction process the day after the first time the rent was unpaid. You may also learn that there are good reasons to have a WRITTEN lease, clearly spelling out the rights and obligations of the landlord and tenant.
