Limits

Age-18 redetermination requires a new application. A parent can help without guardianship, but the adult or legal representative controls voluntary participation and signing.

Beyond Childhood’s checklists and prompts are planning aids derived from official sources. They are not official forms, legal advice, eligibility decisions, or guarantees of funding, capacity, quality, or service.
