The Wisconsin sublease agreement is a legally binding contract with which a tenant can rent their already-leased property to another occupant. The original renter, know as the “sublessor,” will remain on the lease and retain full responsibility for the rental unit. If the new occupant, the “sublessee,” causes property damage or fails to pay rent, the sublessor will be financially liable to the landlord. Before signing the agreement, the sublessor should review their lease to determine whether the landlord’s permission is needed to sublet. However, if the sublessor is a tenant at will (e.g., week-to-week or month-to-month tenant), they are required by law to request approval from the landlord.
