14In Schedule 1 (enfranchisement and extension by sub-tenants), after paragraph 12A insert—
“12B(1)This paragraph applies if—
(a)at the relevant time—
(i)the tenancy in possession is a shared ownership lease (the “original shared ownership lease”), and
(ii)the tenant’s share of the dwelling is less than 100%, and
(b)the landlord who grants the new tenancy (the “new shared ownership lease”) is not the immediate landlord under the original shared ownership lease.
(2)At any time after the grant of the new shared ownership lease—
(a)the immediate landlord under the new shared ownership lease, or
(b)the landlord under any relevant intermediate lease,
may apply to the appropriate tribunal for an order making provision to secure that each relevant intermediate lease is varied to include (if or to the extent that it does not already do so) a payment sharing term.
(3)A “payment sharing term” is a term under which staircasing payments are to be shared between—
(a)the immediate landlord under the new shared ownership lease, and
(b)each landlord under a relevant intermediate lease,
in a way which fairly and reasonably reflects staircasing losses that are incurred after the variation of the lease to include this term.
(4)An order under this paragraph may include—
(a)an order relating to a relevant intermediate lease not specified in the application;
(b)an order appointing a person who is not party to a relevant intermediate lease to execute a variation of the lease.
(5)A lease is a “relevant intermediate lease” if—
(a)the lease demises some or all of the shared ownership premises, and
(b)the lease is intermediate between—
(i)the new shared ownership lease, and
(ii)the interest of the landlord who granted the new shared ownership lease.
(6)In this paragraph—
“shared ownership premises” means the premises demised by the new shared ownership lease;
“staircasing loss”, in relation to a staircasing payment, means the loss that a landlord incurs because of the increase in the tenant’s share in the shared ownership premises to which the staircasing payment relates;
“staircasing payment” means a payment made by the tenant under the new shared ownership lease to their immediate landlord in consideration of an increase in the tenant’s share in the shared ownership premises.”
