If there is no previous child custody determination that is entitled to be enforced under this article and a child custody proceeding has not been commenced in a court of a state having jurisdiction, a child custody determination made under this section remains in effect until an order is obtained from a court of a state having jurisdiction. If a child custody proceeding has not been or is not commenced in a court of a state having jurisdiction, a child custody determination made under this section becomes a final determination, if it so provides and this State becomes the home state of the child. § 63-15-336(B)
If there is a previous child custody determination that is entitled to be enforced under this article, or a child custody proceeding has been commenced in a court of a state having jurisdiction, any order issued by a court of this State invoking emergency jurisdiction must specify in the order a period that the court considers adequate to allow the person seeking an order to obtain an order from the state having jurisdiction. The order issued in this State remains in effect until an order is obtained from the other state within the period specified or the period expires. § 63-15-336(C).
Basically temporary emergency jurisdiction exists if there is an emergency and the child is present in the state. However such jurisdiction only lasts until a state that has previously exercised jurisdiction has time to get involved in the dispute or until a custody action is commenced in a court that would have jurisdiction for an initial case. Emergency jurisdiction can only develop into ongoing jurisdiction when there are no prior custody orders and no action is filed in a state having jurisdiction before South Carolina becomes the child’s home state.
Modification jurisdiction
The power to modify an existing custody order is set forth in § 63-15-332, which sets forth the authority of other states to modify a South Carolina custody order, and § 63-15-334, which sets forth the authority of South Carolina to modify another state’s custody order.
Under § 63-15-332(A)(2) another state can modify a South Carolina custody order if “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.” However, if the child or any party continue to reside in South Carolina, under § 63-15-332(A)(1), it requires that “a court of this State determines that neither 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” before another state can modify a South Carolina custody order.
Basically, before another state can modify a South Carolina custody order either no party nor the child can remain in South Carolina or South Carolina must decide to relinquish jurisdiction.
Similarly, before South Carolina can modify another state’s custody order either no party nor the child can be living in the issuing state [§ 63-15-334(2)] or the court of the issuing state must determine it no longer has exclusive, continuing jurisdiction or that South Carolina would be a more convenient forum. § 63-15-334(1).
The basic analysis for modification jurisdiction is that if a party or the child lives in the issuing state, the issuing state must decline jurisdiction before another state can modify the order. If no one remains in the issuing state, then the jurisdictional analysis is the same as it is for an initial order.
Initial jurisdiction
Jurisdiction for an initial case is set under § 63-15-330. It sets forth four tests for jurisdiction, with each succeeding test only applying if no state meets any of the previous tests. Under this section “[p]hysical presence of, or personal jurisdiction over, a party or a child is not necessary or sufficient to make a child custody determination.” § 63-15-330(C).
The first test in § 63-15-330(A) is “home state” jurisdiction: “this State is the home state of the child on the date of the commencement of the proceeding, or was the home state of the child within six months before the commencement of the proceeding and the child is absent from this State, but a parent or person acting as a parent continues to live in this State.” § 63-15-330(A)(1). If the child has a home state and the child or a parent or person acting as a parent lives within the home state, that is the only state that can exercise initial jurisdiction.
Sometimes, however, there is not a “home state” for the child or no one remains in the home state. In such circumstances, one looks at the “significant connection/substantial evidence” test set forth in § 63-15-330(A)(2):
