There can only be one succession. Provided there has not been a succession before, spouses and registered civil partners can succeed to a tenancy if the tenant dies as well as close family members who have lived with the tenant for at least a year (the law defines who a qualifying family member is so check the full guidance note for a list).  If the tenancy began before 1 April 2012 unmarried partners need to have lived with the tenant for a year to qualify; if the tenancy began after that they are treated the same as spouses.

In April 2012 the Localism restricted statutory successions to spouses and partners only but also allowed social landlords to grant "discretionary successions" to other family members as long as this is written into the tenancy conditions. In Camden we decided to carry on allowing the same family members who could succeed before the Localism Act to succeed after it so all our tenancies have the same succession rights attached (apart from the legal change for unmarried partners referred to above).

Although, ordinarily, a minor can't hold a tenancy, children can succeed to one. There is a separate guidance note for this situation.
