Wyo. Stat. § 20-4-146 (2026)

(a) A tribunal of this state that has issued a child
support order consistent with the law of this state has, and
shall exercise, continuing, exclusive jurisdiction to modify its
child support order if the order is the controlling order and:

          (i) At the time of filing of a request for
modification, this state is the residence of the obligor, the
individual obligee or the child for whose benefit the support
order is issued; or

          (ii) Even if this state is not the residence of the
obligor, the individual obligee or the child for whose benefit
the support order is issued, the parties consent in a record or
in open court that the tribunal of this state may continue to
exercise jurisdiction to modify its order.

     (b) A tribunal of this state that has issued a child
support order consistent with the law of this state may not
exercise continuing, exclusive jurisdiction to modify the order
if:

          (i) All the parties who are individuals file consent
in a record with the tribunal of this state that a tribunal of
another state that has jurisdiction over at least one (1) of the
parties, who is an individual or that is located in the state of
residence of the child, may modify the order and assume
continuing, exclusive jurisdiction; or

          (ii)   Its order is not the controlling order.

    (c)   Repealed By Laws 2005, ch. 103, § 3.

     (d) If a tribunal of another state has issued a child
support order pursuant to the Uniform Interstate Family Support
Act or a law substantially similar to that act which modifies a
child support order of a tribunal of this state, tribunals of
this state shall recognize the continuing, exclusive
jurisdiction of the tribunal of the other state.

     (e) A temporary support order issued ex parte or pending
resolution of a jurisdictional conflict does not create
continuing, exclusive jurisdiction in the issuing tribunal.

    (f)   Repealed By Laws 2005, ch. 103, § 3.
     (g) A tribunal of this state that lacks continuing,
exclusive jurisdiction to modify a child support order may serve
as an initiating tribunal of another state to modify a support
order issued in that state.
