What this means in practice
A notice is usually the first step, not the eviction itself. A landlord generally needs a court order before a tenant can be removed, and changing the locks or cutting utilities to force a tenant out is not allowed in most states.
Serve the notice the way state law requires, keep a copy and proof of delivery, and count the days carefully: some states skip weekends and holidays.
Tenants who receive a notice can often stop the process by paying or fixing the problem within the notice period. Local legal aid offices can explain the options.
