Utah Code § 48-3a-1023: Approval of merger.

(1) A plan of merger is not effective unless it has been approved:

(a) by a domestic merging limited liability company, by all the members of the limited liability company entitled to vote on or consent to any matter; and

(b) in a record, by each member of a domestic merging limited liability company that will have interest holder liability for debts, obligations, and other liabilities that arise after the merger becomes effective, unless:

(i) the operating agreement of the limited liability company in a record provides for the approval of a merger in which some or all of its members become subject to interest holder liability by the vote or consent of fewer than all the members; and

(ii) the member consented in a record to or voted for that provision of the operating agreement or became a member after the adoption of that provision.

(2) A merger involving a domestic merging entity that is not a limited liability company is not effective unless the merger is approved by that entity in accordance with its organic law.

(3) A merger involving a foreign merging entity is not effective unless the merger is approved by the foreign entity in accordance with the law of the foreign entity's jurisdiction of formation.
