Wyo. Stat. § 20-4-148 (2026)

orders.

     (a) If a proceeding is brought under this act and only one
(1) tribunal has issued a child support order, the order of that
tribunal controls and shall be recognized.

     (b) If a proceeding is brought under this act, and two (2)
or more child support orders have been issued by tribunals of
this state, another state or a foreign country with regard to
the same obligor and same child, a tribunal of this state having
personal jurisdiction over both the obligor and individual
obligee shall apply the following rules and by order shall
determine which order controls and shall be recognized:

          (i) If only one (1) of the tribunals would have
continuing, exclusive jurisdiction under this act, the order of
that tribunal controls;
          (ii) If more than one (1) of the tribunals would have
continuing, exclusive jurisdiction under this act:

               (A) An order issued by a tribunal in the current
home state of the child controls; or

               (B) If an order has not been issued in the
current home state of the child, the order most recently issued
controls.

          (iii) If none of the tribunals would have continuing,
exclusive jurisdiction under this act, the tribunal of this
state shall issue a child support order, which controls.

     (c) If two (2) or more child support orders have been
issued for the same obligor and same child, upon request of a
party who is an individual or that is a support enforcement
agency, a tribunal of this state having personal jurisdiction
over both the obligor and the obligee who is an individual shall
determine which order controls under subsection (b) of this
section. This request may be filed with a registration for
enforcement or registration for modification pursuant to W.S.
20-4-173 through 20-4-184, 20-4-193, 20-4-194 and 20-4-197, or
may be filed as a separate proceeding.

     (d) The tribunal that issued the controlling order under
subsection (a), (b) or (c) of this section has continuing
jurisdiction to the extent provided in W.S. 20-4-146 or
20-4-147.

     (e) A tribunal of this state that determines by order
which is the controlling order under paragraph (b)(i) or (ii) or
subsection (c) of this section or that issues a new controlling
order under paragraph (b)(iii) of this section shall state in
that order:

          (i) The basis upon which the tribunal made its
determination;

         (ii)   The amount of prospective support, if any; and

          (iii) The total amount of consolidated arrearages and
accrued interest, if any, under all of the orders after all
payments made are credited as provided by W.S. 20-4-150.

     (f) Within thirty (30) days after issuance of an order
determining which is the controlling order, the party obtaining
the order shall file a certified copy of the order in each
tribunal that issued or registered an earlier order of child
support. A party or support enforcement agency obtaining the
order that fails to file a certified copy is subject to
appropriate sanctions by a tribunal in which the issue of
failure to file arises. The failure to file does not affect the
validity or enforceability of the controlling order.

     (g) A request to determine which is the controlling order
shall be accompanied by a copy of every child support order in
effect and the applicable record of payments. The requesting
party shall give notice of the request to each party whose
rights may be affected by the determination.

     (h) An order that has been determined to be the
controlling order, or a judgment for consolidated arrearages of
support and interest, if any, made pursuant to this section
shall be recognized in proceedings under this act.
