Family facts may be relevant to the legal analysis, so supply them to counsel rather than assuming every household is treated identically.
Do not self-assign a different queue
Ask the attorney to identify any applicable family-based availability rules and their requirements using current authority. The sources reviewed for this guide do not resolve those detailed mechanics. Also confirm initial family inclusion and relationship eligibility separately; an availability discussion does not substitute for deciding who can participate.
Ask the two family questions in order and do not merge them. The first is who may be included at all, which depends on relationship eligibility and on facts such as a child age and marital status. The second is whether any family-based availability rule applies to the classification identified.
The first must be settled before the second becomes meaningful. Hypothetical example: a household assumes an adult child will be included because the child is financially dependent and lives at home. Dependency is not the test, and discovering that late can change the shape of the whole plan.
Ask the attorney to identify the applicable rules using current authority and to state what was assumed. The sources reviewed for this guide do not resolve those detailed mechanics, and an availability discussion is not a substitute for deciding who can participate.
