The Utah 5-day notice to vacate for tenancy at-will is a notice served on an individual occupying the premises without a written or oral lease, relaying that they must leave within five (5) days. This situation can occur when there is an unpermitted guest on the property who refuses to leave (a squatter), or if the rental agreement has expired and the tenant refuses to vacate the premises. If the tenant remains on the property after the five (5) days have expired, the landlord can file for an eviction.
