(c) Except as otherwise provided in § 14.5-602 of this title, a person that under this subtitle is authorized to represent a settlor that lacks capacity may receive notice and give a binding consent on behalf of the settlor.

(d) A representative may act on behalf of the individual represented with respect to a matter arising under this title, whether or not a judicial proceeding concerning the trust is pending.

(e) In making decisions as a representative of an individual, the representative may consider the general benefit accruing to the living members of the family of the individual.
