A sublease is a legal agreement or contract between a tenant (the sublessor) and a third party (the sublessee) that allows the sublessee to rent all or part of the leased premises from the tenant for a specified period, term, or rent amount. Subleasing occurs when a tenant rents out their rented property or space to another party, known as the sublessee or subtenant, while still being responsible for fulfilling their obligations under the original lease agreement with the landlord or property owner. Sublease arrangements are common in real estate leasing transactions, particularly in commercial leases, where tenants may have excess space or wish to temporarily vacate premises while continuing to pay rent and maintain leasehold rights. Sublease terms, conditions, and restrictions are governed by the original lease agreement and may require landlord approval, adherence to lease terms, and compliance with local rental laws and regulations. Subleasing allows tenants to offset rental costs, share occupancy expenses, or monetize unused space, while providing sublessees with temporary or flexible leasing options, cost savings, and access to desirable locations or facilities without a long-term lease commitment.
