Subchapter II. Jurisdiction
§ 1920. Initial child custody jurisdiction.

(a) Except as otherwise provided in § 1923 of this title, a court of this State has jurisdiction to make an initial child custody determination only if:

(2) A court of another state does not have jurisdiction under paragraph (1) of this subsection, or a court of the home state of the child has declined to exercise jurisdiction on the ground that this State is the more appropriate forum under § 1926 or § 1927 of this title; and
a. The child and the child's parents, or the child and at least one parent or a person acting as a parent, have a significant connection with this State other than mere physical presence; and
b. Substantial evidence is available in this State concerning the child's care, protection, training, and personal relationships;
(3) All courts having jurisdiction under paragraph (1) or (2) of this subsection have declined to exercise jurisdiction on the ground that a court of this State is the more appropriate forum to determine the custody of the child under § 1926 or § 1927 of this title; or
(4) No court of any other state would have jurisdiction under the criteria specified in paragraph (1), (2) or (3) of this subsection.
(b) Subsection (a) of this section is the exclusive jurisdictional basis for making a child custody determination by a court of this State.
(c) Physical presence of or personal jurisdiction over a party or a child is not necessary or sufficient to make a child custody determination.
