No, Chas. A judge decides what 'essentials' are, and you don't spend the trust money on them anyway. Everything Liv needs, such as food, clothing, accommodation, even holidays, are to be paid for by her legal guardian, not by dipping into her fund.
If there is some amazing opportunity for Liv, that might justify spending some of her money, the Judge might allow it, but in my experience, they are very, very reluctant to do so.
