Here is the explanation of the law in Wisconsin
For evictions filed before 3/1/14, the landlord must arrange with the sheriff to move and store any property left behind. Only the sheriff can decide if something is trash to be thrown away. The sheriff must tell you within 10 days where your property is being stored and how much it costs to get it back. They must give 30 days' notice before they throw it out. Only the sheriff has the authority to remove the tenant or their property. In Milwaukee County, the landlord must hire bonded movers. In other counties, landlords can choose to purchase their own bond of insurance. Wis. Stats. 799.45(2) & (3)
For , if the landlord wrote in the lease that they won't move and store property left behind, they can do anything they want with your property during eviction, without involving the sheriff (except to notify the sheriff that they're handling it themselves). The sheriff must still be there to remove you from the property. If the lease doesn't say anything about property left behind, the landlord has to follow the rules listed above for evictions before 3/1/14. If the lease say something else about dealing with property, the landlord must follow the rules in the lease. It is illegal for a landlord to change this rule in the middle of a lease without the tenant's permission. Wis. Stat. 799.45(3m), 2013 Wis. Act 76, Secs. 40-57 Eff. 3/1/14.
