This section applies (subject to subsection (6)) to—
(a) a transfer of an occupation contract by the contract-holder;
(b) a transfer by a joint contract-holder of his or her rights and obligations under an occupation contract.
The transfer must be signed or executed by each of the parties to the transfer.
If the contract requires the landlord's consent to the transfer, the transfer must also be signed or executed by the landlord.
But subsection (3) does not apply if the landlord is treated as having consented under section 84(6), (8) or (10).
A transfer to which this section applies is of no effect if it does not comply with subsection (2) and, if it applies, subsection (3).
This section does not apply to a transfer in accordance with a term included in the contract under section 139 or 142 (certain transfers of fixed term standard contracts).
