The tenant may request an updated disclosure statement from the landlord before the transfer of the commercial lease.
A related concept of assignment is novation wherein, by agreement with all parties, one contracting party is replaced by a new party.
While novation requires the consent of all parties, assignment needs no consent from other non-assigning parties.
An assignment may not transfer a duty, burden or detriment without the express agreement of the assignee.
The right or benefit being assigned may be a gift (such as a waiver) or it may be paid for with a contractual consideration such as money.
