This section answers some common questions about subletting. Expand All Where can you sublet?Write the information of all parties involved in the apartment lease, including the lessee, the sublessee, and others. Subletting, also known as subleasing, involves renting out a property or a portion of it that you are currently leasing, to a new tenant. A sublease agreement is drawn up in these situations, specifying key terms between you, the original tenant, and your friend, the subtenant. You must include the landlord or property manager, and most likely get written permission to go ahead with the lease takeover. However, most leases require landlord written consent before subleasing can occur, as noted in Massachusetts Legal Help guidelines. A sublease agreement is a legal contract signed between a tenant and a third party allowing the latter to rent out the entire property or any part of it. In Massachusetts, a sublease agreement must meet certain criteria to be valid. Create your Massachusetts sublease agreement to rent your unit.
