Utah Code § 81-15-104: Arbitration agreement.

(1) An arbitration agreement shall:

(a) be in a record signed by the parties;

(b) identify the arbitrator, an arbitration organization, or a method of selecting an arbitrator; and

(c) identify the family law dispute the parties intend to arbitrate.

(2) Except as otherwise provided in Subsection (3), an agreement in a record to arbitrate a family law dispute that arises between the parties before, at the time, or after the agreement is made is valid and enforceable as any other contract and irrevocable except on a ground that exists at law or in equity for the revocation of a contract.

(3) An agreement to arbitrate a child-related dispute that arises between the parties after the agreement is made is unenforceable unless:

(a) the parties affirm the agreement in a record after the dispute arises; or

(b) the agreement was entered during a family law proceeding and the court approved or incorporated the agreement in an order issued in the proceeding.

(4) If a party objects to arbitration on the ground the arbitration agreement is unenforceable or the agreement does not include a family law dispute, the court shall decide whether the agreement is enforceable or includes the family law dispute.
