I am trying to parse the qualification “if the beneficiary ceases to be a vulnerable person” in FA 2005 S.37. In the case in mind, an autistic child receiving DLA at the middle level and at least £30k in tax and local authority (including bilingual learning assistant, child tax credit, etc.) benefits, I see the child as a future Alan Turing or Greta Thunberg. He is first in his class in French and maths. Yet he will not be reassessed for DLA at least until age 16. Is that when he could “cease[] to be a vulnerable person”? All modern scholarship agrees that autism is for life. Kiddo’s trust holds 38% of a rental flat plus an investment portfolio; kiddo has substantial JISA and JSIPP. Will there be conflicts at age 16? At 18? Because kiddo has a claim to American citizenship (an unusual fact situation) we did put in his trust deed that the governing law could be changed to a U.S. state if he ever emigrated. But he’d never meet U.S. Social Security norms for a special needs trust and that would create further curiosities including invoking a relevant provision of FA2005 as to non-residents. Any ideas?
