“(1) A tenancy under which a dwelling-house is let as a separate dwelling is a secure tenancy at any time when the conditions described in sections 80 and 81 as the landlord condition and the tenant condition are satisfied. …. (3) The provisions of this Part apply in relation to a licence to occupy a dwelling-house (whether or not granted for a consideration) as they apply in relation to a tenancy. ….”
“The tenant condition is that the tenant is an individual and occupies the dwelling-house as his only or principal home; or, where the tenancy is a joint tenancy, that each of the joint tenants is an individual and at least one of them occupies the dwelling-house as his only or principal home.”
“A person is qualified to succeed the tenant under a secure tenancy if he occupies the dwelling-house as his only or principal home at the time of the tenant’s death and either— (a) he is the tenant’s spouse or civil partner , or (b) he is another member of the tenant’s family and has resided with the tenant throughout the period of twelve months ending with the tenant’s death; unless, in either case, the tenant was himself a successor, as defined in section 88.”
“(1) The tenant is himself a successor if— (a) the tenancy vested in him by virtue of section 89 (succession to a periodic tenancy), or (b) he was a joint tenant and has become the sole tenant ….” unless, in either case, the tenant was himself a successor, as defined in section 88.”
“The method adopted by the 1980 Act to deal with transmissions is different. It reflects the fact that a secure tenancy is different in nature from a statutory tenancy. Whereas the statutory tenancy is unassignable, not an estate in land but a mere "personal right of occupation" (see Lord Greene MR in Carter v SU Carburetter Co[1942] 2 KB 288 , 291), a secure tenancy is an orthodox estate in land which, subject to specific restrictions in the 1980 Act, can be assigned, held in joint names, pass by survivorship and be disposed of by will on death. Thus, while a statutory tenancy can pass from one person to another only in very limited circumstances (such as the statutory transmission on death or by a court order on divorce) a secure tenancy can in principle pass in any way permissible at common law.”
