The recent case of Solihull MBC v Hickin serves as a reminder that on the death of a joint tenant, the tenancy automatically vests in the remaining tenant as a result of the doctrine of survivorship. If that person is no longer in occupation as their only or principal home then the tenancy will have lost its security under the Housing Acts and can be legitimately determined by the service of a valid notice to quit, depriving an occupying family member of any right to succeed or remain in occupation.
