Lease extension The Leasehold Reform, Housing and Urban Development Act 1993 (LRHUDA 1993) provides a right for individual tenants with long leases to acquire a new lease with an extended term if certain conditions are satisfied. The right is considered in detail in Practice Note: Guide to lease extensions of flats under the Leasehold Reform, Housing and Urban Development Act 1993. The process is begun by a tenant giving a notice under LRHUDA 1993, s 42. For further information, see Practice Note: Guide to lease extensions of flats under the Leasehold Reform, Housing and Urban Development Act 1993. If the LRHUDA 1993, s 42 notice is valid and is not withdrawn, the default position is that an obligation arises between the landlord and the tenant to grant and to accept a lease—LRHUDA 1993, s 56.
