The Wisconsin 5-day notice to quit for imminent threat is served on a tenant who has seriously threatened the safety and wellbeing of another tenant on the property, or their child, providing them with five (5) days to move off the property. This measure was put in place to enable both landlords and tenants to evict an individual whose presence in a rental unit places others in imminent danger.
For there to be no opportunity for the tenant to cure, the landlord must receive certified documentation stating that the offending tenant poses a serious threat (as listed in 704.16(3)(b)(2)). That said, a 5-day notice to quit for a lease violation can be served even if there is no proof available via legal documentation. In either case, the offending tenant will be able to contest the allegations in court, requiring that the landlord present further credible evidence to prove they are guilty.
