The Evolution of a Lease Provision: Sublease and Assignment

In the absence of a lease provision restricting subleasing and assignment, common law permits a tenant to freely sublease its leased premises or assign its leasehold interest in the leased premises. In order to provide for maximum landlord control over a tenant's ability to sublease or assign its leasehold interest, while at the same time balancing the need of tenants for an exit strategy, modern forms of leases contain extensive assignment and sublease provisions. This article traces the manner in which those provisions have evolved over the years.
