You can lease your apartment to another person. If you will be returning to live in your apartment after the other person leaves, this is called a sublease.The landlord chooses whether or not to allow this type of agreement. It's only legal if the lease you signed says you can sublet. Most leases do not allow this in any way, shape or form. Subletting is when thirdparty rents or "subleases" the property from the original tenant. Improve the ability of and to encourage owners of property to maintain standards of habitability commensurate with the quality of life of the Township of Wayne. A true sublease will result in the premises being returned to the original tenant before the end of the term, if only for a day.
