§ 20-5-302 — Exclusive, continuing jurisdiction

(a) Except as provided in W.S. 20-5-304, a court of this
state which has made a child custody determination consistent
with W.S. 20-5-301 or 20-5-303 has exclusive, continuing
jurisdiction over the determination until:
(i) A court of this state determines that the child,
the child's parents and any person acting as a parent do not
have a significant connection with this state and that
substantial evidence is no longer available in this state
concerning the child's care, protection, training and personal
relationships; or
(ii) A court of this state or a court of another
state determines that the child, the child's parents and any
person acting as a parent do not presently reside in this state.
(b) A court of this state which has made a child custody
determination and does not have exclusive, continuing
jurisdiction under this section may modify that determination
only if it has jurisdiction to make an initial determination
under W.S. 20-5-301.
