Wyo. Stat. § 20-4-183 (2026)

state.

     (a) If W.S. 20-4-193 does not apply, upon petition a
tribunal of this state may modify a child support order issued
in another state which is registered in this state if, after
notice and hearing, the tribunal finds that:

         (i)     Repealed By Laws 2005, ch. 103, § 3.

         (ii)    The following requirements are met:

               (A) Neither the child, the obligee who is an
individual nor the obligor resides in the issuing state;

               (B) A petitioner who is a nonresident of this
state seeks modification; and

               (C) The respondent is subject to the personal
jurisdiction of the tribunal of this state; or

          (iii) This state is the state of residence of the
child, or a party who is an individual is subject to the
personal jurisdiction of the tribunal of this state and all of
the parties who are individuals have filed consents in a record
in the issuing tribunal for a tribunal of this state to modify
the support order and assume continuing, exclusive jurisdiction.
     (b) Modification of a registered child support order is
subject to the same requirements, procedures and defenses that
apply to the modification of an order issued by a tribunal of
this state and the order may be enforced and satisfied in the
same manner.

     (c) A tribunal of this state may not modify any aspect of
a child support order that may not be modified under the law of
the issuing state, including the duration of the obligation for
support. If two (2) or more tribunals have issued child support
orders for the same obligor and same child, the order that
controls and shall be so recognized under W.S. 20-4-148
establishes the aspects of the support order which are
nonmodifiable.

     (d) In a proceeding to modify a child support order, the
law of the state that is determined to have issued the initial
controlling order governs the duration of the obligation of
support. The obligor's fulfillment of the duty of support
established by that order precludes imposition of a further
obligation of support by a tribunal of this state.

     (e) On issuance of an order by a tribunal of this state
modifying a child support order issued in another state, the
tribunal of this state becomes the tribunal having continuing,
exclusive jurisdiction.

     (f) Notwithstanding subsections (a) through (e) of this
section and W.S. 20-4-142(b), a tribunal of this state retains
jurisdiction to modify an order issued by a tribunal of this
state if:

          (i)    One (1) party resides in another state; and

          (ii)   The other party resides outside the United
States.
