In some cases, 18 year olds can sue for long-term support. In Oklahoma, a child is entitled to support until 18 unless that child is regularly attending a full time high school. Then, CS can run through the age of 21.

There is also a statute from 1910 or so which says parents have a duty to provide for their children.... a 35-year-old ne'er do well has yet to attempt to sue his parents for support under that statute, so who knows?

Also, child support doesn't go to the child, it goes to the parents or guardians. I don't think this young lady would have much of a shot under Oklahoma law, but the attorney arguing the point might get props from the judge for such a creative legal theory before she dismisses the case.
