Part 1: Leasehold houses Section 4: Series of leases whose term would extend beyond 21 years
Section 4 establishes what is meant by a ‘series of leases’ under section 3(5).
	Subsection (1) sets out that a lease ("the original lease") can form a series of leases where terms extend beyond 21 years, if conditions A to C are met when the original lease is granted.
	Subsection (2) sets out condition A as the original lease does not have a long term under section 3(2), (3) or (4).
	Subsection (3) sets out condition B as the provision for the grant of another lease of the same house ("the new lease") is included in (a) the original lease or (b) any related arrangements.
	Subsection (4) sets out condition C as the total duration of (a) the term of the original lease, (b) the term of the new lease (if granted) and (c) the term or terms of any subsequent leases (if granted) would exceed 21 years.
	Subsection (5) clarifies that if the new or subsequent leases have the option for terms of varying durations, the longest duration is always used.
	Subsection (6) details that a lease is a "lease of the same house" if the property contained in the lease (if granted) would consist of one house, being the house in the original lease.
	Subsection (7) details that arrangements are "related arrangements" if they are entered into in connection with the grant of the original lease.
	Subsection (8) details that a lease is a subsequent lease if (a) it is not a new lease, (b) it is a lease of the same house and (c) provision for the grant of the lease (i) is included in the original, (ii) would be included in the new lease (if granted) or (iii) would be included in any other lease that itself would be a subsequent lease.
