Family terms are set out in the official material and have been stated in terms of additional amounts for a spouse and eligible unmarried children under twenty-one. Confirm the current position from the official source before planning.
Confirm family terms at the source
Hypothetical example: Households naturally want a single figure for the whole family, and the published material has described per-person amounts for a qualifying spouse and eligible unmarried children under twenty-one in addition to the principal. Because those figures and conditions belong to a framework that has been revised, they should be taken from the current official page rather than from any summary, including this one. Two further points apply regardless of the amounts.
A child's age can move during any multi-stage process, so a household with a teenager should identify when age would be assessed. And eligibility and admissibility questions apply to each person individually, so a family should not assume that an assessment satisfied for one participant resolves the position for another.
