A sublet, or sublease agreement, adds someone new to an existing lease. Usually the new person (subletter) replaces someone who is moving out.In Minnesota, subleasing is a common practice where a tenant, known as the sublessor, rents out their rented space to another tenant. The difference lies in who ends up in charge of the lease. Subletting is the same as subleasing; the two words are interchangeable. As long as your landlord, or state law, approves, anyone can sublet. A sublet allows direct landlord communication with the subtenant, unlike a sublease, where the legal relationship is between the primary and subtenant. This publication describes what the law requires of both landlords and tenants and also describes some terms that are in typical leases. Subletting involves a tenant renting out their rental property to another person, called a subtenant, under a lease or rental agreement. The difference lies in who's in the know and who's in control of the property.
