What is the rule governing ASSIGNMENTS and SUBLEASES?
In the absence of some prohibition in the lease, T may freely transfer in an assignment or in a sublease.
In the lease, L may prohibit T from assigning or subletting without L's prior written approval.
However, once L consents to ONE transfer by T, L WAIVES the righ tto object to future transfers by T, unless L EXPRESSLY RESERVES that right.
NY: Unless the lease provides otherwise, a residential T may NOT ASSIGN without L's consent. L CAN UNREASONABLY withhold consent to assign.
NY: By contrast, T in a residential building having four or more units has the RIGHT TO SUBLEASE subject to L's WRITTEN CONSENT. Consent CANNOT be unreasonably withheld (deemed "consent" when unreasonably withheld).
