Legal Question in Landlord & Tenant Law in California

Give the tenant who does not want to pay rent a 3-Day Notice to Pay Rent or Quit. If, after the expiration of the 3-day period the tenant has still not paid or vacated, you will need to file an unlawful detainer, which is a lawsuit asking the court to forfeit the lease or rental agreement and evict the tenant.

You have the same rights as a sublessor against the subtenant as a landlord has against a tenant. As Mr. Hoffman summarized, you proceed with a notice to pay or quit followed by an unlawful detainer action.
