What it means
An unlawful detainer is the legal name for an eviction lawsuit in many states. It's used against tenants who don't pay or whose leases ended, and sometimes against former owners after foreclosure. The process requires proper notice, a court filing, a hearing and then a sheriff or marshal to carry out the removal. Owners can't change locks or shut off utilities to force someone out.
After a 3-day notice to pay went unanswered, the owner filed an unlawful detainer. The court ruled in about a month, and the sheriff scheduled the lockout two weeks later.
