A Montana sublease agreement is a rental arrangement that allows a tenant to rent out a leased residence to a third party, referred to as a “sublessee.” While the agreement is separate from the master contract with the landlord, it cannot contain provisions that are in contravention of the original terms. Furthermore, state law requires the sublessor to obtain the written permission of the landlord or their agent before transferring possession of the rental unit to a third party. Subleases are commonly used to cover periods of absence, to complete the original tenant’s term, or to supplement rental costs.
