In the world of real estate, the word “sublease” usually refers to a rental agreement between a tenant who is legally bound by a lease and wishes to either get out of it by renting the property to someone else and then moving away or wants to lease part of the space they are renting to someone else. When one is sharing the space, the person taking on the sublease will pay their rent directly to the first tenant. When taking over a lease completely, the new person will pay rent to the original landlord. Within certain rental agreements, particularly at nicer, more modern apartment complexes, subleasing is not allowed. This is because most landlords want to have greater control over who is living in their property. Even if subleasing is allowed, a tenant cannot change any of the terms of the original lease or the rules of the property without permission from the landlord.
