(a) Adoptions finalized by a Court with appropriate jurisdiction in a foreign country or in another state or territory of the United States shall be valid in this State provided that the final adoption decree was issued in full accord with the adoption laws of that foreign country or that state or territory, and that the child was not brought into this State until after the finalization of adoption.

(b) No adoption proceeding or order therein which occurs in a foreign country or in another state or territory of the United States shall be valid or recognized by any court in this State as respects persons who are residents of this State where a child is brought into this State prior to the finalization of the adoption, unless the adoption proceedings shall be in substantial compliance with the adoption laws of this State. This subsection shall not apply to any adoption proceedings or order therein initiated in a foreign country or in another state or territory of the United States as respects persons who are not residents of this State at the time of the commencement of such adoption proceedings.

(c) Adoptive parents seeking an order certifying the validity of their foreign adoption decree shall file the decree with the Family Court in the county in which they reside. An affidavit shall be filed with the decree indicating that the decree was issued in accordance with the laws of the issuing jurisdiction and that the adopted child was not brought into Delaware until the adoption was finalized. Also included in the affidavit shall be the name by which the child is henceforth to be known. The Court shall review the affidavit, decree and other documents, and if the adoption meets the requirements of this section, the Court shall issue an order certifying the validity of the adoption including the child’s American name.
