I've got a situation in WI whereas the current tenant in a property elected not to renew his lease as he was moving. The lease expires today at Noon. A new tenant signed a lease for the same unit, beginning two days from now at Noon. Two days ago, the current tenant left a message with the landlord that he could not find a new place to live, so he is not going to move out. The landlord has not been able to establish contact with the current tenant, and the new tenant is expecting to move in 48 hours from now.

Does the landlord and/or new tenant have any way to take immediate action? The landlord would need to see a judge and get an eviction (which would take more than 2 days to get him out), right? Or could the police remove the tenant for tresspassing or something of that nature?

Thanks
