A household summary can be useful, but record each person’s outstanding documents and notices where they differ.
Avoid assuming simultaneous completion
The official FAQ addresses initial family inclusion, while individual records may still require attention. Ask counsel which notices apply to everyone and which concern only a named person. Before arranging a joint move, confirm what each family member must complete; a principal applicant’s update should not be silently extended to the entire household.
Do not assume that family members move through the process together or that one entry covers everyone. Track each person separately, with their own record of what has been submitted, acknowledged or requested, and their own dates. Individuals can and frequently do progress at different rates for reasons ranging from documentation to their own circumstances, and a household record that shows a single status conceals exactly the information that matters.
Where a family member's position appears to have stalled while others have advanced, establish what specifically is outstanding for that person rather than waiting for the group to be updated collectively. This also matters for anyone approaching an age threshold, since their timeline may need attention that the household's collective progress does not reveal. Ask at each update specifically what has changed for each named person, rather than accepting a single statement about the household, since a collective report is what conceals an individual delay.
