If my whole family applies for H&C together, does each person's hardship get assessed separately?

Generally, yes, even when a family applies together on one H&C application, each family member's specific circumstances are meant to be genuinely considered as part of the overall assessment, rather than the whole family being treated as a single undifferentiated unit whose hardship is identical across the board. A child's best interests, for instance, have to be assessed based on that specific child's own circumstances, separate from a parent's establishment or hardship factors.

That said, the family's circumstances are also considered together in a practical sense, since family members' lives are usually intertwined — a parent's establishment often supports the family's overall picture, and disruption to one member frequently affects the others. The application is generally decided as a whole for the family, but the reasoning behind that decision is meant to reflect each person's specific situation, not a single averaged assessment.

Because it's easy for a family application to focus mostly on the principal applicant's story and underdevelop the specific circumstances of other family members, especially children, a strong family H&C application should include distinct, well-documented evidence for each person, ideally reviewed with a lawyer, rather than assuming one family narrative adequately covers everyone.
