EXCLUSIVE, CONTINUING JURISDICTION

A. Except as otherwise provided in Section 16 of this act, a

court of this state which has made a child custody determination

consistent with Section 13 or 15 of this act has exclusive,

continuing jurisdiction over the determination until:

1. A court of this state determines that neither the child, the

child and one parent, nor the child and a person acting as a parent

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

2. 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 Section 13 of

this act.
