Utah Code § 75A-4-303: Intent to exercise -- After-acquired power.

Unless the terms of the instrument exercising a power of appointment manifest a contrary intent:

(1) except as otherwise provided in Subsection (2), a blanket-exercise clause extends to a power acquired by the powerholder after executing the instrument containing the clause; and

(2) if the powerholder is also the donor of the power, the clause does not extend to the power unless there is no gift-in-default clause or the gift-in-default clause is ineffective.
