This Q&A considers a situation whereby with a freehold building, for example, there is a retail shop at ground floor level and two residential flats immediately above and both flats are let on long leases to tenants who are qualifying tenants for the purposes of receipt of a section 5 notice under the Landlord and Tenant Act 1987. This Q&A considers whether, if the landlord wishes to sell the building, the obligations for service of a section 5 notice would be satisfied by service of such notice on only one of the long leasehold qualifying tenants given that one has to serve notice on no less than 90 % of the qualifying tenants.
