There is an obligation to pay child support for an adult disabled child for as long as the child is dependent on a parent due to disability. The obligation to pay such child support does not end simply because the child finishes school.
A parent must also provide food, shelter, care, and clothing to an adult child who cannot support herself due to disability and has no other means of obtaining these necessities. Failing to provide these things to the adult disabled child is a misdemeanor. Even if a child receives state assistance or disability payment, this does not automatically make the child self-supporting.
