Utah Code § 6-2-121

(1) Subject to other law of this state governing a person from another state serving as a fiduciary in this state, a court with jurisdiction may appoint a person serving as an assignee in an assignment in another state, or the person's nominee, as an ancillary assignee relating to assigned assets located in this state or subject to the jurisdiction of a court in this state, if: (a) the person or nominee would be eligible to serve as an assignee under Section 6-2-103; and (b) the appointment furthers the person's possession, custody, control, or disposition of an assigned asset under the assignment in the other state. (2) A court with jurisdiction may issue an order that implements an order entered in another state appointing or directing an assignee or otherwise concerning an assignment in the other state. (3) Unless a court with jurisdiction orders otherwise, an ancillary assignee appointed under Subsection (1) has the rights, powers, and duties of an assignee appointed under this chapter. (4) A person in possession, custody, or control of an assigned asset in this state, other than a creditor holding a lien or a right of setoff or recoupment relating to the asset, shall, on notification in a record by an ancillary assignee appointed under Subsection (1), turn over the asset to the ancillary assignee.
